What's new

Six new games: a two-step De La Riva ladder, a two-step single-leg X ladder, Smash Half Guard, and Duck Under Hit. Two more games now have a reference video.

Why it helps: A coach can climb the Pearson De La Riva games from the shin pin to the sweep or pass, run Smash Half Guard and Duck Under Hit, and climb the Golden Jiu Jitsu single-leg X pair from the finish back to the hip touch. Causing Posts and Connection and Destabilization open a checked reference clip.

Added

• De La Riva Destabilization: Hands or Hips to the Mat vs Shin Pin the Hip (`/game/guard/de-la-riva-destabilization-hands-or-hips-to-the-mat-vs-shin-pin-the-hip/`) — Developing, bottom-advantage, standard safety.

Changed

• Causing Posts and Connection and Destabilization now have a free reference video.
• Find reports 416 games.
• Asset cache `?v=123`. `version.js` is 1.57.7.

Game pages on phones get a one-row header, so the clock and video sit higher.

Why it helps: A coach on a phone opens a game and the clock sits one row higher. Find stays marked, and a wide screen still has the way back to the games.

Changed

• On a game page, phone widths hide the ← Games link in the header. The link stays in the page, so a wide screen still shows it. The logo and Find still open the catalog.
• Find is marked on a game page, the same way it is marked on Find.
• Asset cache `?v=122`. `version.js` is 1.57.6.

Tell the room is the full cue under the timer, a held pin stays on Pins, More stays on the screen, Class and Ladders match the nav, and a forward ladder climbs to the last rung.

Why it helps: A coach reads the whole cue before the round, still sees Coach after opening More, and does not lose a real pin game from the Pins filter. X-guard and clamp climb to the last rung. Single-leg X stays off the stand-up map.

Asset cache `?v=121`. `version.js` is 1.57.5.

The top bar is down to Find, Class, and Ladders. Everything else is still one tap away in More, links open without a redirect, and three dead links now go where they should.

Why it helps: A coach or student landing before class sees three places, Find, Class, and Ladders. Map, Filter & Find, Start here, and the rest are still one tap away in More. Links open on the first request, and the three dead links now go where they should.

Changed

• The header is Find, Class (`/sessions/build`), and Ladders (`/series`). Map moves into More. Nothing is removed.
• More keeps every link, grouped as Start, Learn, and About, and adds Map and Filter & Find. View as Student or Coach stays on that menu.
• The footer keeps Sources, Privacy, and the gym line, and adds a quiet Reference line: Invariants, Library, Map, Film.
• Find is marked on `/` and `/find`. Class is marked on `/sessions`. Ladders is marked on `/series` and Start here. Map and Saved mark their More link.
• Internal links drop the trailing slash. A slash URL still redirects, then opens.
• The method index link now points at `/method`. Class Builder points at `/sessions/build`. Inside Positional Game points at `/game/guard/the-sweep-and-posture-battle`.
• Asset cache `?v=120`. `version.js` is 1.57.4.

The reference video now sits right under Tell the room, one tap from the timer, and the score tally stays out of the way until you turn it on.

Why it helps: A coach on a phone between rounds can show the move without opening Show full game. The clock stays clear until they turn the score on.

Changed

• On a game with a reference video, the video sits under Tell the room. It stays click-to-play. The page has no iframe until Play. Open video still goes to the source. A game with no video shows nothing new.
• The score tally on a game page stays behind Score, off until you turn it on. This phone remembers the choice. Reset still clears the count. The class Run page tally is unchanged.
• Asset cache `?v=119`. `version.js` is 1.57.3.

A four-rung X-guard ladder and a two-rung clamp half guard ladder are in the catalog, along with more free reference videos on games that were already here.

Why it helps: A coach can climb the Pearson X-guard games from single-leg X to the reversal with a free video on each rung, run the Golden Jiu Jitsu clamp half guard pair, and open a checked reference clip on eight more games.

Added

• Single-Leg X to X-Guard: Build the X vs Clear the Hooks (`/game/guard/single-leg-x-to-x-guard-build-the-x-vs-clear-the-hooks/`) — Developing, bottom-advantage, standard safety. Rung 1 of X-Guard Ladder (Pearson Brazilian Jiu-Jitsu). Free YouTube embed at 0:10.
• X-Guard Switch: Change Sides vs Clear the Hooks (`/game/guard/x-guard-switch-change-sides-vs-clear-the-hooks/`) — Proficient, bottom-advantage, standard safety. Rung 2 of X-Guard Ladder (Pearson Brazilian Jiu-Jitsu). Free YouTube embed at 0:46.

• X-Guard Reversal: Sweep or Take the Back vs Clear the Hooks (`/game/guard/x-guard-reversal-sweep-or-take-the-back-vs-clear-the-hooks/`) — Developing, bottom-advantage, standard safety. Rung 4 of X-Guard Ladder (Pearson Brazilian Jiu-Jitsu). Free YouTube embed at 1:49.
• Clamp Half Guard: Free the Knee Line vs Get On Top or Knee Shield (`/game/passing/clamp-half-guard-free-the-knee-line-vs-get-on-top-or-knee-shield/`) — Developing, top-advantage, standard safety. Rung 1 of Clamp Half Guard (Golden Jiu Jitsu Coaches Hub). No free clip of this exact game.
• Clamp Half Guard: Free the Leg and Pin vs Sweep or Open Guard (`/game/passing/clamp-half-guard-free-the-leg-and-pin-vs-sweep-or-open-guard/`) — Developing, top-advantage, standard safety. Rung 2 of Clamp Half Guard (Golden Jiu Jitsu Coaches Hub). No free clip of this exact game.

Changed

• Maintain Arm Isolation credits coach Greg Souders at Standard Jiu-Jitsu. Greg Souders stays on its tags.
• Eight existing games now have a free reference video. Twelve more are stamped VIDEO_SKIPPED after no exact public clip.
• Find reports 410 games.
• Asset cache `?v=118`. `version.js` is 1.57.2.

On a phone, Find opens on the games, and a search that misses only offers a way to clear what is actually set.

Why it helps: A coach between rounds no longer scrolls past a second New games link, a second Class tonight link, and the Student, Coach, and ruleset switches before the list. Those switches stay in Filters, and they still remember the choice in this browser. An empty search names only the filters that are on.

Changed

• The Find header no longer repeats New games or Class tonight. Both stay in the nav.
• Student, Coach, All, ADCC, and IBJJF No-Gi sit in the collapsed Filters panel. Same buttons, same `gg.role` and `gg.ruleset` memory. Only the More menu copies stay.
• An empty Find list names only what is set. A nonsense search with nothing else on shows Clear search. Relax ability, Relax safety, and Clear filters still show when those filters are on.
• Asset cache `?v=117`. `version.js` is 1.57.1.

Read pages: invariants, the library, and the changelog now read like a clean article, easy on a phone between rounds.

Why it helps: A coach or student can read an invariant, the library, or the changelog as one calm column on a phone between rounds. The words and the games stay the same.

Changed

• Invariants, the library, method pages, and the changelog share one article template: a mono kicker, an uppercase title, one gold rule, and a 68-character measure.
• Invariant and method game lists stay in the same order and open the Mat from a row card with the family bar.
• Asset cache `?v=116`. `version.js` is 1.57.0.

Nine catalog games — a 4-rung Standard Jiu-Jitsu all-levels ladder (start connected at the legs, the arm, the hips, then behind, and submit or take the back), a 2-rung Greg Souders ADCC camp ladder (hand fight to get behind and lock your hands, then submit from behind vs turn to face), a Souders standing leg-entanglement game (locked hands at the hips or shoulders vs submit, reverse, or stand), and a 2-rung Legion Jiu Jitsu standing front headlock ladder (hands to the mat vs head back up, then collar tie to front headlock vs strip and disconnect) — each with a free video.

Why it helps: A Proficient room in any leg entanglement can finish on the legs or come up and take the back, or free the leg, counter-submit, or pass. A Developing room can start from a figure-four grip and chain threats until a submission or a back take, or get free and hide the back. A Developing room in side control, arm around the hip, can submit, or reverse, recover seated open guard, or stand. A Developing room from all fours with a waist connection can submit from any pin, or sit to open guard, stand and turn to face, or reverse. A Developing room standing can hand fight to get behind and lock the hands, then a Proficient room can submit from chest to back, or turn to face and get on top or back to their feet. A Proficient room standing and entangled can clear the entanglement and lock the hands at the hips or shoulders, or submit, reverse, or stand if they break apart. A Foundations room can touch the hands to the mat from a standing front headlock, or get the head back up, then lower the head below the armpit and snap on a front headlock from a collar tie and an inside tie, or strip the ties and disconnect. Six of these are elevated safety: the four all-levels rungs, submit from behind, and the standing entanglement. Tap and release stays in the constraints. The other three are standard safety. All nine are nogi-sensible. Free YouTube embeds from Standard Jiu-Jitsu and Legion Jiu Jitsu. Nothing plays until the tap. No invented wins. Those coaches are the sources. This catalog did not write the games.

Rung 2 of Connect, Then Submit or Take the Back: Legs, Arm, Hips, Behind (Standard Jiu-Jitsu All Levels Class). Bottom player on their side, top player with a figure-four grip. Top stays close, separates the arm, and chains threats with no lag until a submission or a back take. Lose every threat and the game is lost. Bottom gets free of the threat and hides the back. Tap and release stays in the constraints. Same Standard Jiu-Jitsu video, later start (4:33).
• Side Control, Arm Around the Hip: Submit vs Reverse, Seated Guard, or Stand (`/game/pins/side-control-arm-around-the-hip-submit-vs-reverse-seated-guard-or-stand/`) — Developing, top-advantage, elevated safety.

Same Standard Jiu-Jitsu video, later start (8:28).
• All Fours, Waist Connection: Submit from Any Pin vs Seated Guard, Stand and Face, or Reverse (`/game/turtle/all-fours-waist-connection-submit-from-any-pin-vs-seated-guard-stand-and-face-or-reverse/`) — Developing, role-rotating, elevated safety. Rung 4 of Connect, Then Submit or Take the Back: Legs, Arm, Hips, Behind (Standard Jiu-Jitsu All Levels Class). Bottom player on all fours, top player connected around the waist.

Not a series rung. Top starts standing and entangled, feet on the outside. Top clears the entanglement and locks the hands around the hips or shoulders. Bottom submits, reverses, or gets up to their feet if the two break apart. Tap and release stays in the constraints. Same ADCC Camp Part 1 video, later start (26:27).
• Standing Front Headlock: Hands to the Mat vs Head Back Up (`/game/front-headlock/standing-front-headlock-hands-to-the-mat-vs-head-back-up/`) — Foundations, role-rotating, standard safety.

Six catalog games — a Coastal Jiu Jitsu winner-stays berimbolo, a 2-rung Standard Jiu-Jitsu standing ladder (overhook versus underhook, then shooter versus upper body), a Standard Jiu-Jitsu submit-while-under-the-elbows pinning game, and a 2-rung Linus von Schrenk head-position defense ladder (single leg, then body lock with the hips apart) — each with a free video.

Why it helps: A Proficient room can play winner-stays berimbolo: the attacker submits from anywhere, and the player getting boloed wins by getting on top for three with the back closed off. A Developing room standing can climb overhook versus underhook (butt or back, or hands around the head), then shooter versus upper body (ankle in the armpit, a lift, or going behind, against putting them on their butt or back). A Developing room can submit while something stays under the elbows, or the bottom player gets both elbows in. A Developing room can defend with head position: disconnect a single, then break a body lock with the hips apart. Two of these are elevated safety: the berimbolo and the under-the-elbows submission. Tap and release stays in the constraints. The other four are standard safety. All six are nogi-sensible. Free YouTube embeds from Coastal Jiu Jitsu, Standard Jiu-Jitsu, and Linus von Schrenk. Nothing plays until the tap. No invented wins. Those coaches are the sources. This catalog did not write the games.

Added

• Berimbolo, Winner Stays: Submit vs Get on Top for Three (`/game/back/berimbolo-winner-stays-submit-vs-top-for-three/`) — Proficient, role-rotating, elevated safety. Not a series rung. Any berimbolo start. The attacker submits from anywhere, and can keep re-attacking the back. The player getting boloed gets on top and holds it for three with the back no longer exposed.

• Overhook vs Underhook: Butt or Back, or Hands Around the Head (`/game/standup/overhook-vs-underhook-butt-or-back-or-hands-around-the-head/`) — Developing, role-rotating, standard safety. Rung 1 of Overhook, Underhook, Then the Legs (Standard Jiu-Jitsu at 10th Planet South Bay). Standing over-under. The overhook stays an overhook. The overhook player puts them on their butt or back, or catches the head and connects the hands.

Rung 2 of Overhook, Underhook, Then the Legs (Standard Jiu-Jitsu at 10th Planet South Bay). Standing, opposite jobs.

Class from a series: one tap on any series builds tonight's class from the rung your room is on, ready to run.

Eleven catalog games from frankthetankjj — a 2-rung standing ladder (grip fight for underhook and wrist control; then lock up a single, a body lock, or a front headlock), a single-leg race, a 3-rung mount ladder (elbows down, two-on-one or double unders vs reverse or guard; same start, submit; one elbow up, head and arm or back take vs elbow down, reverse, or escape), an S-mount both sides game, an open guard three-flanks passing game, a chopping-block side control submission game, and a 2-rung turtle ladder (no connected hands, hip to the mat vs stand and disconnect; seat belt and a hook or hip down past the legs vs guard or stand) — each with a free video.

Why it helps: A Foundations room standing can race to an underhook and wrist control, then lock the hands for a single or a body lock, or snap down to a front headlock. A Foundations room standing can race to pick up a single leg. A Developing room in mount, elbows down, can expose one elbow for a two-on-one or keep both elbows up, or reverse or get back to guard. The same start can go on to a submission or the gift wrap. With one elbow already up, the top player can finish the head and arm or take the back, or the bottom player can get the elbow down, reverse, or get out during the back take. A Developing room in mount with the elbows up can reach S-mount on both sides, or get both elbows back down to the ribs. A Developing room in open guard can flank three times and lock the hands, or get both feet inside and both hands connected. A Developing room in the chopping-block side control can submit, or get the elbow down or sweep. A Foundations room in turtle, hands disconnected, can get the hip to the mat, or stand up and disconnect. A Developing room in turtle can connect a seat belt and a hook, knock the hip down past the legs, or finish a rear-naked choke, or get a guard back or stand up and walk away. Four of these are elevated safety: the mount submission, the head and arm or back take, the chopping block, and the turtle seat belt with the rear-naked choke. Tap and release stays in the constraints. The other seven are standard safety. All eleven are nogi-sensible. Free YouTube embeds from frankthetankjj. Nothing plays until the tap.

Ten catalog games — a 3-rung Eco Submission Grappling ladder (lock your hands vs stand up from bottom on the back; butterfly lock the body vs sweep or stand; side control get the head vs stand or get on top), a 2-rung Andris Brunovskis gi ladder (lasso, keep a sleeve, attach to the shoulder line vs break both sleeves; shoulder line attached, submit or come up on top vs both arms in or out), Charles Roy's Between Two Worlds body-lock game, a 2-rung Red River Judo youth ladder (kumi-kata grip race; grips then a foot off the ground), a frankthetankjj mount game (capture a foot vs double unders), and a Sensei Sandy kids seated stand-up race — each with a free video.

Why it helps: A Foundations room with the bottom player on their back can lock the hands around the head and an arm or the body, or stand up. A Foundations room in butterfly can lock the hands around the body from the waist up, or sweep and come up or stand. A Foundations room in side control can get a hand under the head or wrap over it, or stand up or get on top. A Developing gi room in lasso can keep a sleeve and attach the legs to the shoulder line or get between the legs, or break both sleeves. A Developing room with the legs already on the shoulder line can submit or come up on top, or get both arms in or both arms out and stay on top. A Developing room seated between butterfly and closed guard, with the top player's hands locked behind the lower back, can double-lock the center or a limb, or leg-lock or take the back. A Foundations youth gi room can race sleeve-and-collar against sleeve-and-high-collar, then get a foot off the ground after the grips. A Foundations room in mount, elbows down, can capture a foot or get double unders. A Foundations kids room, both seated, can race to stand up for a 3 count. Three of these are elevated safety: the lasso shoulder-line attachment, the shoulder-line submission game, and Between Two Worlds with its leg and limb double locks. Tap and release stays in the constraints. The other seven are standard safety. Seven are nogi-sensible. The lasso game and the two Red River Judo kumi-kata games are gi only. The Red River Judo ladder is a youth class, and the seated stand-up race is a kids game.

Nine catalog games from The Brinkmanship Lab — a 3-rung Chris Alfar ladder (standing hamstring pressure to the back; leg capture wedge to the back; knee-to-knee race to the back), a 2-rung Charles Roy ladder (circle the body on a hip connection; over the head with a shoulders-and-arm double lock), one more Charles Roy mutual-connection game (kneeling single leg double locks), two gi open guard grip games (stay on the collar; stay on the sleeve), and a half guard get-out game — each with a free video.

Why it helps: A Developing room can stay on both feet, press the hamstrings, and win with a closed connection behind the back, or put the standing player on a hip or both hands. A Developing room from a leg-capture wedge can get chest to back, or take the back or sit them down. A Developing room knee to knee can race to the first chest-to-back connection. A Developing room connected to the hips can circle the body, or lock the legs or get to both knees. A Developing room going over the head can finish the circle or lock the shoulders and an arm, or lock the legs, get to both knees, or connect the hands around the hips with a leg between. A Developing room on a kneeling single can double-lock a limb or lock the center. A Developing gi room can stay on the collar, or stay on a sleeve, while the passer strips that grip for 3 seconds or passes. A Developing room stuck in half guard can sit up, get to the knees, or lock the legs, or the top player can lock the hands around them. Four of these are elevated safety: the over-the-head arm-lock capture, the kneeling single-leg limb game, and the two gi games whose bottom win includes locking a triangle. Tap and release stays in the constraints. The other five are standard safety. Seven are nogi-sensible. The two grip games are gi only. Free YouTube embeds from Chris Alfar and Charles Roy via The Brinkmanship Lab, taught at the Accélérateur Martial 12 camp at Jiu-Jitsu Saguenay; from The Brinkmanship Lab / Jiu-Jitsu Saguenay for the two gi games, seeded by Andris Brunovskis; and from The Brinkmanship Lab / Jiu-Jitsu Saguenay for the half guard game, which credits Greg Souders and John Danaher. Nothing plays until the tap. No invented wins. Those coaches are the sources. This catalog did not write the games. Behind the Head, Elbow to Elbow stayed out: the defender’s double-lock was the coach describing his goal, not a stated win.

Six catalog games — two Chris Alfar standing games (underhook vs overhook connection race; single leg off-balance plus second connection vs cover the head), three Charles Roy ground-to-standing games (double octopus hips plus shoulders or ankle; single-leg guard pull entangle and stand up; off-balance top hips above vs close the legs or wrestle up), and one Joshua Settlage closed guard game — each with a free video.

Why it helps: A Developing room can stay on an underhook or an overhook and win by picking up a leg, locking the body, or covering the head. A Developing room on a standing single can put the partner on two hands or hips and make one more connection, or cover the attacker's head without pulling the leg out. A Developing room in closed guard can pass the hips or take the back, or sweep, take the back, or stand up. A Developing room in double octopus can lock the hips together with the shoulders or the ankle. A Developing room can sit back from a single leg and both entangle and stand up, or take the back or lock the hips and ankle. A Developing room with the top player already off balance can get the hips above and lock the shoulders, or close a leg connection or wrestle up. All six are standard safety.

Three catalog games — one Bodega Jiu Jitsu Kimura Dilemma game (figure-four strangle or twist vs free head and arm) plus two Rob Cole Ecopalooza leg-entanglement games (ashi false grip vs clear the knee line; open 50/50 upgrade or false grip) — each with a free video.

Why it helps: A Developing room can figure-four the legs for a strangle or twist the arm behind the back from a kimura grip with the legs around the head and arm, or free the head and arm. A Foundations room can catch a one-arm false grip on the heel from ashi, or clear the knee line and escape. A Developing room in open 50/50 can upgrade closer to the hip and across the body, or catch a false grip. All three are elevated safety.

Why it helps: A Developing room can get chest-to-chest or chest-to-back from knee-shield half guard, or get both feet between the top player's knees. A Foundations room can complete the three single-leg X conditions on both legs, or free the trapped leg. A Foundations room can capture the toes, get under the heel, and connect the hands on both sides of both legs, or free the leg. The two single-leg games are elevated safety.

Changed

• Find reports 350 games. The index slug stays off that board.
• Asset cache `?v=100`. `version.js` is 1.49.1.

Color-coded games: every list now shows a family stripe and a one-line code, so you can spot passing, guard, legs, or back games at a glance.

Why it helps: A coach scanning Find, a class picker, a ladder, or New games can see the family and the game code on one line, without opening the card. The Mat stays timer-first.

Added

• Family stripe and a mono code line on Find, the Plan picker, Series ladders, New games, Saved, and Recently played. The Mat title block uses the same stripe and a one-line code.
• A collapsed Families key inside Filters, with a dot and a count for each family.
• Asset cache `?v=99`. `version.js` is 1.49.0.

Search from anywhere: press / or tap the magnifier, type a game, position, or code, and jump straight to its Mat.

Why it helps: A coach who already knows the game can open it from any page, on a phone or a laptop, without scrolling back to Find.

Added

• Command palette on every page. Press `/` or Ctrl-K / Cmd-K, or tap the magnifier in the header. Results group games, pages, and tools. Recent games and the last class come from what this phone already remembers. Nothing new is stored.
• Asset cache `?v=98`. `version.js` is 1.48.0.

New look, same mat: tighter layout, ruled panels, and code-style labels so you can scan games and pages faster.

Why it helps: Find, a Mat, and Plan stay in the same order on a phone. Desktop pages sit on a 75rem sheet with 68-character reading lines. Mono labels mark codes, filters, and versions so the gold stays on the action.

Changed

• Scorebook shell: warm surface panels, 1px rules, uppercase page headings, and a self-hosted IBM Plex Mono label face. Dark mat and gold are unchanged.
• Asset cache `?v=97`. `version.js` is 1.47.0.

Not played in 2 weeks: when you build a class, one tap puts games your room hasn't played lately at the top, using only what this phone remembers.

Why it helps: A coach building tonight's class can put games this phone has not played or run in the last two weeks at the top of Add a game and Change game. Recent games stay in the list, with the same quiet date flag. Nothing new is stored. The phone only reads the play marks and class history it already keeps.

Added

• Plan's Add a game and Change game pickers show a Not played in 2 weeks chip when this phone already has `gg.played` or `gg.class-history`. It stays off until you tap it. On, games with no play and no class run in the last 14 days come first, in the same order as before. Games played or run in that window follow, still in their old order, with a quiet `ran <date>` or `played <date>` flag.

Changed

Four catalog games — three Sub Science CLA games (Two Sleeves back-to-chest vs double lapel tsukuri game; De La Riva to the wedge vs any leg entanglement berimbolo game; two-on-one connect the hands vs free the arm) plus Rob Biernacki's ADCC-scoring front headlock game (pin or score the back vs stand up or sit to guard) — each with a free video.

Why it helps: A Developing room in the gi can turn in from both sleeve grips and get back to chest, or reach both lapels at chest height. A Proficient room can get to the wedge from De La Riva, or enter any leg entanglement. A Developing room can score a back take with the hips on the mat or pin both shoulders for 3 seconds from front headlock, or stand up, sit to half guard, or break the grips and take the back. A Foundations room can connect the hands from a two-on-one anywhere from ankle to neck, or free the arm. The front headlock game is elevated safety.

Competition film on Find: filter to games you can watch played at ADCC, IBJJF, and other events, and spot them on the card.

Why it helps: A student who learns by watching can narrow Find to the games linked from those competition clips, and see which cards have film, without leaving Find for /film.

Added

• Find's Filters gain a Competition film chip next to Has video. It keeps games whose slug is linked from a film clip. It combines with the other filters, search, role, and ruleset, and it clears with them.

Five catalog games — four Ground Game Theory CLA lab games (arms-low hand-to-spine back finish path; tripod butterfly inside-leg pass; shin-wedge turtle climb-or-leg-finish; Choi/Troy bar back-to-floor vs free the arm) plus a Craig Hutchison / Josh Beam collar-and-pant chest-connection vs feet-back-in-front pass — each with a free video.

Why it helps: A Developing room can keep the arms low and touch a hand to the spine from behind, or break the connections and turn to face. A Developing room can hold one leg inside for 3 seconds from a tripod butterfly underhook, or sweep, reverse, submit, or entangle. A Developing room can climb from shin wedges behind the knees to chest-to-back or finish a lower-limb submission, or stand up or counter.

Share a game: send the Mat page to a training partner from your phone's share sheet, or copy the link on desktop.

Why it helps: A student or coach who already found tonight's game can send that Mat page to a training partner or a room group chat in two taps. The phone opens the share sheet with the game title and the page address. On a computer, the same control copies the link. No account. It still works when the gym wifi drops.

Added

• Every game page has Share with Save and the other quiet controls. It stays under Start timer and Tell the room.
• Where the phone has a share sheet, Share opens it with the catalog title and the canonical game URL. Cancelling the sheet shows nothing.
• Otherwise Share copies the link and shows "Link copied."

Six catalog games — a 7 Jiujitsu foot-to-knee untangle and re-entangle leg entanglement game, two MATS Jiu-Jitsu Academy off-balancing games (three points of contact, kneeling underhooks), a MATS low knee shield half guard game, a Clinch Academy knee cut pass game, and a Cyanide BJJ back arm trap to back triangle game — each with a free video.

Why it helps: A Developing room can untangle a foot-to-knee entanglement, put the hips or hands down, and re-entangle, or pass on the outside with a shin touch. A Developing room can keep three points of contact and float a passer, or get a leg outside the hip from kneeling underhooks. A Developing room can pass a low knee shield and isolate the head and arm, or finish a knee cut into cross body. A Developing room can reach a back triangle from chest-to-back with one arm trapped, or escape the back. The leg entanglement and the back triangle are elevated safety.

Add to calendar: save tonight's class as a calendar event with every game in the notes and a link back to Run.

Why it helps: A coach who built tonight's class can put it on their phone calendar in two taps. The event uses the class title and the class length. The notes list every game in order, with its section and minutes, plus a link that reopens that class in Run. The file is built on the phone. No account. It still works when the gym wifi drops.

Added

• Plan and Run show Add to calendar next to Copy link. It stays quiet, under Build and Run. With no games in the class, the control stays off.
• The panel asks for a date (today) and a start time (6:00 PM), then downloads a calendar file. Open it to add one event to Apple Calendar, Google Calendar, or Outlook.

Seven catalog games — a 2-rung Pearson Brazilian Jiu-Jitsu half guard passing ladder, a Carsahh butterfly wedge game, two Josh Beam / Greg Souders closed guard arm-in-arm-out games, a Coach Rob Cole rear standing knuckle-cover game, and a Bren Teaches Movement / Cal Jones back-to-the-wall foot sweep scoring game — each with a free video.

Why it helps: A Developing room can climb a half guard pass: free the knee from chest-to-chest half guard, then free the ankle from three-quarter mount. A Developing room can win a butterfly wedge before the top player body locks and flattens them. A Foundations room can hold head and arm control, or start from an overhook and lock arm in, arm out. A Foundations room can lock the hands from behind while the partner covers the knuckles and turns to face. A Developing room can score a wall touch, a takedown, or a foot sweep with their back near a wall.

Class history — reopen any of your last 10 classes and see which games you already ran this week.

Why it helps: A coach opens Plan and sees the last 10 classes they ran on this phone. One tap reopens a class in Run, or loads it back into the builder to tweak. While building tonight's class, a game that was in a class from the last 14 days shows the day it last ran, so the same three games do not fill every night.

Added

• Plan keeps Recent classes under Print class pack and Copy link. The section stays closed until you open it. Each row shows the date, how many games, and the first few titles, with Open in Run and Edit. Clear history removes the list. With no history, the section stays off.
• `gg.class-history` stores the last 10 classes as `{ plan, ran }`, newest first. `plan` is the same encoded class string as the share link. `ran` is the date (`YYYY-MM-DD`). Running the same class again on the same day moves that row to the top instead of adding a copy. The 11th class drops the oldest. `gg.last-class` still resumes the last class.
• Games in the class list, and in the games you pick while building, show a quiet "ran Oct 2" when that game was in a class from the last 14 days. The date is the most recent one. With no history, the flag stays off.

Eight catalog games — a 4-rung TheModernGrapplingCoach shoot-or-steal takedown ladder, a Brick City leg-lock counter, a Better Grappler turtle game, and two Sub Science judo games — each with a free video.

Why it helps: A Developing room can climb a grip ladder and shoot or steal the shot: front body lock, then double biceps and head, then double wrists, then a Russian tie. A Developing room can counter a leg lock by stealing inside position and entangling, or flatten a turtle while the bottom player stands or reverses. A Foundations room can play Into the River, and a Developing room can push or throw from an overhook lane.

Played log — tap Played after a round and see what you've actually trained.

Seven catalog games — two Dapto Jiu Jitsu back-attack finishing games, The Grapple Lab 3-rung closed-guard elbow-control ladder, and Pearson Brazilian Jiu-Jitsu side-scissor triangle and low-single games — each with a free video.

Why it helps: A Developing room can finish a rear strangle while the top arm is trapped, or finish a straight jacket from the back and from chest to chest after the escape. A Foundations room can climb The Grapple Lab closed-guard elbow ladder: inside or outside the elbows, then a chest-to-chest sweep or the outside position, then a back take or sweep from outside the elbows. A Developing room can finish a side-scissor triangle, or wrestle a low single from the elbow inside to the top.

Chest to back with the top arm trapped under the top leg and the strangling arm halfway in. Top finishes a one-handed or two-handed strangle. Bottom gets the trapped arm out. Release on the tap stays in the constraints. Source: Coach Alvi (Dapto Jiu Jitsu), No-Gi Foundations Class: 6 Ecological (CLA) Games. Free YouTube embed at 4:21.
• Straight Jacket: Finish From the Back or On Top (`/game/back/straight-jacket-finish-from-the-back-or-on-top/`) — Developing, top-advantage, elevated safety. Not a series rung. Both hooks and a straight jacket. Top strangles from the back, or comes on top with an underhook and finishes an armbar, chicken-wing kimura, or head-and-arm strangle. Bottom gets both shoulders to the mat out of danger, or becomes the top player out of danger. Release on the tap stays in the constraints. Same Dapto Jiu Jitsu class video, later start (5:43).
• Inside or Outside the Elbows vs Stand and Open (`/game/guard/inside-or-outside-the-elbows-vs-stand-and-open/`) — Foundations, role-rotating, standard safety. Rung 1 of Closed Guard Elbow Control (The Grapple Lab). Closed guard, top's hands on the body. Bottom holds inside-elbow control or the outside-elbow position for 3 seconds. Top stands and opens the legs. No sweeps and no submissions. Source: The Grapple Lab, 4 Tasked Based Games To RAPIDLY Improve your Closed Guard. Free YouTube embed at 2:56.
• Chest to Chest: Sweep or Go Outside (`/game/guard/chest-to-chest-sweep-or-go-outside/`) — Foundations, role-rotating, standard safety. Rung 2 of the same ladder. Already chest to chest inside the elbows. Bottom sweeps or holds the outside-elbow position for 3 seconds. Top postures out and opens the legs, or holds half guard for 3 seconds. Same Grapple Lab video, later start (6:09).
• Outside the Elbows: Back Take or Sweep (`/game/guard/outside-the-elbows-back-take-or-sweep/`) — Foundations, role-rotating, standard safety. Rung 3 of the same ladder. Bottom is already outside the elbows, arm pulled across (a sleeve grip in the gi, or the wrist in no-gi). Bottom takes the back or sweeps. Top stands out or holds half guard for 3 seconds. The start uses a sleeve or a wrist, so this rung is not tagged nogi-friendly. Same Grapple Lab video, later start (10:14).
• Side Scissor: Triangle or Flatten and Stand (`/game/submissions/triangle/side-scissor-triangle-or-flatten-and-stand/`) — Developing, bottom-advantage, elevated safety. Not a series rung. Side scissor with a near-side overhook and a far-side biceps post. Bottom finishes the triangle. Top flattens the shoulders and gets to the feet. Release on the tap stays in the constraints.

• Low Single: Elbow Inside to Top (`/game/takedowns/low-single-elbow-inside-to-top/`) — Developing, top-advantage, standard safety. Not a series rung. Low single with elbows and knees on the mat. Attacker gets the elbow inside the trapped leg and wrestles to top. Defender frees the leg and goes behind the arms to force turtle.

Changed

• Find reports 317 games. The index slug stays off that board.
• Asset cache `?v=85`. `version.js` is 1.40.1.

Series on Mat — see your rung while you play.

Why it helps: An athlete already climbing a ladder sees which rung this round is, and can open the next one, without leaving the mat. Nothing is shown until this phone has marked a rung.

Added

• On a Mat that belongs to a series, the connection strip shows “Rung N of M” and a link to the next rung when this browser has ladder progress (`gg.camp`). When the ladder is finished, the strip says “Series complete”.
• With no saved marks, the strip stays as it was. The cue is filled by script. With JavaScript off, the timer still comes first and More stays closed.

Changed

• Asset cache `?v=84`. `version.js` is 1.40.0.

Room display QR — scan into big clock mode for the wall phone.

Why it helps: A coach prints the class pack or opens the code on Run. The wall phone scans it and lands in Room display for this plan. Nobody types the address or adds `display=1` by hand.

Added

• Room display QR on Run, next to Room display, when a plan is loaded. The same code is in the class pack on Class tonight and the full plan.
• The scan address is this plan's Run URL with `display=1` added once. Other plan parameters stay. The link is written under the code.
• The mark uses the same offline QR code as QR for class.

Changed

• Asset cache `?v=83`. `version.js` is 1.39.0.

Resume last class — one tap back into the plan you just ran.

Why it helps: A coach finishes class, leaves, and the next day opens the same plan without building it again. The plan stays on this phone. It still opens when the network is down.

Added

• Last class on Class tonight, on the full plan, and on an empty Run. It opens the last plan you ran, in the same game order, with the same minutes. Nothing is kept until you start a Run.
• With no last class yet, Run says "No last class yet". Plan hides the control.

Changed

• Asset cache `?v=82`. `version.js` is 1.38.0.
• Privacy notes that the last class you ran stays on this device.

Fourteen new competition clips on Film.

Why it helps: A coach can show another real match, then open the games that train that skill. The clip stays a poster until the tap. Nothing plays when the page loads.

Added

• Fourteen competition clips on Film, from UWW, the IJF, ADCC, WNO, and other public match footage. Each one links one to three games that train the skill named in the clip.
• Film cards are a poster and a play button. A tap loads the youtube-nocookie player. With JavaScript off, that poster is a link to YouTube.

Changed

• Asset cache `?v=81`. `version.js` is 1.37.0.
• Privacy notes that Film loads YouTube only when you tap play.

Map that fits the phone — no clipped positions at 390px.

Why it helps: A coach or athlete can tap a position and read its label. The mat behind the map stays on the phone instead of drawing a wide rectangle that the page cuts off.

Fixed

• The positional map’s mat rectangles use the same box as the SVG viewBox. Focused and Territory resize them with the view. At 390px those rectangles no longer run off the left and right of the screen.
• Asset cache `?v=80`. `version.js` is 1.36.0.

Same quiet video players everywhere, and no stale asset version leftovers.

Why it helps: A Mat reference clip stays off until you tap Play. Related videos stay off the player, and it fits a phone. The icon uses the same asset version as the rest of the page.

Changed

• All 21 Mat reference players use `rel=0` and `playsinline=1` on the youtube-nocookie address. Play still waits for a tap. No new clips, and no autoplay.
• `game.js` follows the page asset version. The old hardcoded `ASSET_V` fallback is not used.
• Favicon, icon, and apple-touch links use that same asset version.
• Asset cache `?v=79`. `version.js` is 1.35.1.

See the start from above — top-down diagrams for the ground Start here games.

Why it helps: A beginner sees the shape of the start in one glance. Side control reads as a T. Front headlock reads head-to-head over turtle. The picture is on the page before the round starts.

Added

• Top-down start diagrams for Connection Hold — Grips Off, Side Escape, Finishing the Pass — From the J-Point, Passing the Knee Line, and Front Headlock Establish and Hold. Torso, head, and limbs. Gold is the top player. Warm-neutral is the bottom player. The picture matches that game's Position.
• The same diagrams on those Start here rows and beside the Mat title. They are in the HTML, so they show with JavaScript off. The timer stays first.

Changed

• Asset cache `?v=78`. `version.js` is 1.35.0.

Put the phone on the wall. The room can see the clock and what to do.

Why it helps: A coach props a phone or tablet where the room can see it. The clock, the line to tell the room, and the round or switch cue are large enough to read from the mats. Exit display brings the usual Mat back.

Added

• Room display on every Mat and on Run the class. It opens the same page with `?display=1`. Exit display takes that off the address. Pasting `?display=1` does the same.
• In that view the clock is the large type. Tell the room sits in high contrast beside it in landscape, and above it in portrait. REST, Switch roles, and the round count use the same cues as the Mat timer, in larger type. Nav, More, and the score counters stay out of the way. Start, the bell, and Next still work. The screen stays awake while the timer runs.
• With JavaScript off, the Mat still shows Tell the room and the round length. Start stays on the timer.
• The class QR note says a coach can open Run class and tap Room display, or add `?display=1` to the run address.

Changed

• Asset cache `?v=77`. `version.js` is 1.34.0.

Stuck on the mat? Name the problem. Get the games that train it.

Why it helps: A student who is stuck on mat night opens Start here, names the problem, and gets games that already train it. Start here and Diagnostic use the same list. No new curriculum.

Added

• Stuck? on Start here, above the eight foundations games. Six problems, the same ones Diagnostic already names. Tap one and the matching games show, each linked to its Mat.
• With JavaScript off, those six problems stay on the page as links into Diagnostic. Diagnostic opens that problem when the address includes `?problem=`.
• Stuck? in More, pointing at that Start here section.

Changed

• Asset cache `?v=76`. `version.js` is 1.33.0.

Tap to keep score under the timer. Counts only — no declared winner.

Why it helps: Partners can keep a first-to-N count, or a reset count, on the mat without counting on their fingers. The numbers stay anonymous. The page never names a winner.

Added

• Two tap counters under the clock on every Mat, and on Run the class while a game is showing. Tap a number to add one. Minus takes one away, and it stops at zero.
• Symmetric games label the counters A and B. A game with two roles uses those roles, such as Top and Bottom. Counts stay in this page's memory for the current round. Nothing is saved, and nothing is compared.

Changed

• Asset cache `?v=75`. `version.js` is 1.32.0.

Find games you can watch, and fill the starter ladder so more Mats have a tap-to-play clip.

Why it helps: A student can filter Find to games that already have a free reference video. Start here and the passing ladder were checked for a free source clip. Where none showed the game, the catalog stays empty of a fake embed.

Added

• Has video, in Find filters. It keeps only games with a real reference video. It works with the other filters. Clearing it brings the full catalog back.
• Mat reference videos stay a poster until you tap Play. The player is youtube-nocookie, with a direct Open video link. Nothing starts on its own.

Changed

• The eight Start here games and the six Standing vs Seated Passing rungs were checked on 2026-10-05. No free clip showed those games, so each one is marked checked and has no embed.
• Asset cache `?v=74`. `version.js` is 1.31.0.

See what's new without digging through the changelog.

Why it helps: A coach or athlete opens New games and sees what landed in the last 30 days, newest first. Find cards keep a quiet New chip for 14 days after that ship. No account.

Added

• `/new/` lists catalog games whose changelog Added bullet names that game's `/game/…/` path, when the ship date is within 30 days of this release. Newest first. Each card links to the mat and shows the added date. Games with no such path are left off. Dates are not guessed.
• A New chip on Find cards, and on `/new/` cards, for games added within 14 days of this release.
• New games in More, and on Find beside Class tonight.
• With JavaScript off, `/new/` is still the list.

Changed

• Asset cache `?v=73`. `version.js` is 1.30.0.

Put tonight's class on the whiteboard: scan the QR, open the plan.

Why it helps: A coach builds tonight's plan, then shows or prints a QR. A phone camera opens the same shared class link as Copy link. Students see the plan and can tap Run class. No texting a long URL. The code is drawn on the phone. Nothing is sent to a QR service.

Added

• QR for class on Class tonight, once the class has a game. The caption is "Scan to open tonight's plan." The address is the same one Copy link copies.
• The print class pack leads with that QR and the link written out, so a paper on the whiteboard still works if the code does not scan.
• An empty class has no QR. With JavaScript off, the shared address is still on the page as text.

Changed

• Asset cache `?v=72`. `version.js` is 1.29.0.

Gym wifi dies; the timer, Tell the room, and tonight's plan still work.

Why it helps: A coach who already opened Find, a Mat, or tonight's class can keep going when the gym network drops. The timer, Tell the room, and Run class stay on the phone. Film clips stay on YouTube and say so.

Added

• This browser keeps the shell, Start here, and pages you open, including the last class plan. A new visit online picks up the next asset version and drops the old cache.
• A quiet offline line: cached pages work, and Film needs a signal. It sits at the bottom of the screen, under the timer.
• Film still lists the real clips. Offline, each player says it needs a network. Nothing plays until you tap, and only when you are online.

Changed

• Asset cache `?v=71`. `version.js` is 1.28.0.

Run tonight's class from one screen: tell the room, start the round, tap Next.

Why it helps: A coach builds tonight's class, or opens a shared class link, and taps Run class. The screen shows the game, the line to tell the room, and the Mat timer. Next moves to the next game. No account.

Added

• Run class on Class tonight once the class has a game, and on the shared class link.
• Run view at `/sessions/run`. It shows the game count, the name, Tell the room, and the same Mat timer (bell, wake lock, rounds and rest). Next and Prev. The last Next ends on Class done, with Back to plan.
• A drill added with Add drill before it stays in that slot.
• With JavaScript off, the run page lists that class's games in order, as links to each mat page.

Changed

• Asset cache `?v=70`. `version.js` is 1.27.0.

Five Souders games — a double-under passing ladder, closed-guard connect/trap/entangle versus a standing shin touch, and a play-the-whole-space ladder — each with a free video.

Why it helps: A Developing room can climb Greg Souders’ double-under passing ladder: hands past the legs from under both knees, then the same connection from behind the ankles. A Developing room can play closed guard against a standing passer: connect under the elbow, trap head and arm, or entangle once the partner is grounded, while the standing player shin-touches from outside the legs. A Developing room can play the whole space from feet-inside on the mat to a standing single-leg knee-to-ankle put-down. Free Standard Jiu-Jitsu YouTube embeds. Nothing plays until the tap. No invented wins. Greg Souders (Standard Jiu-Jitsu) is the source. Not System JJ originals.

Added

• Double Unders to Hands Past the Legs (`/game/passing/double-unders-to-hands-past-the-legs/`) — Developing, top-advantage, standard safety. Rung 1 of Double-Under Passing (Souders). Top starts with both arms under both knees and connects the hands around the hips or shoulders while past the legs. Bottom gets both feet inside, sits up and disconnects, or closes the legs around the shoulders or head and arm. Source: Greg Souders (Standard Jiu-Jitsu), CLA Double Under Passing @ Next Level MMA. Free YouTube embed.
• Behind the Ankles to Hips or Shoulders (`/game/passing/behind-the-ankles-to-hips-or-shoulders/`) — Developing, top-advantage, standard safety. Rung 2 of the same ladder. Top starts standing behind the ankles, gets behind the knee pits, then connects past the legs. Bottom gets both feet inside the legs, sits up and away, or traps the shoulders. Feet inside the biceps does not count on this rung. Same seminar video, later start.
• Connect, Trap, or Entangle vs Shin Touch (`/game/guard/connect-trap-or-entangle-vs-shin-touch/`) — Developing, bottom-advantage, elevated safety. Not a series rung. Closed guard. Top stands, opens, and shin-touches from outside the legs. Bottom connects under the elbow, traps head and arm, or entangles once the partner is grounded. Tap or yell release stays in the constraints. Source: Greg Souders (Standard Jiu-Jitsu), CLA Guard Games @ Team Laurien and Alex. Free YouTube embed.
• Keep Them Down From Feet Inside (`/game/leg-locks/keep-them-down-from-feet-inside/`) — Developing, role-rotating, elevated safety. Rung 1 of Play the Whole Space (Souders). Attacker starts with feet between the knees and both hands on the ankles, and wins by an entanglement while they stay down, a back touch from the feet, or hands locked around the hips. Defender stands and breaks every connection. Tap or yell release stays in the constraints. Source: Greg Souders (Standard Jiu-Jitsu), Playing the Whole Space with CLA. Free YouTube embed.
• Knee to Ankle, Then Put Them Down (`/game/takedowns/knee-to-ankle-then-put-them-down/`) — Developing, top-advantage, elevated safety. Rung 2 of the same ladder. Standing single leg held at the knee. No win counts until the grip has moved to the ankle, then put them down and entangle, get the hips, or touch the back. Defender frees the leg, or stands back up with no connections. Tap or yell release stays in the constraints. Same seminar video, later start.

Changed

• Find reports 310 games. The index slug stays off that board.
• Asset cache `?v=69`. `version.js` is 1.26.0.

30 more competition clips on Film, plus filters by position.

Why it helps: A coach can scan the clips by position, then open the games that train that skill. Nothing plays until the tap.

Added

• 30 more competition clips on Film. Position filters: All, Takedowns, Throws, Passing, Guard, Back, Leg locks, Chokes, and Arm locks. Each chip shows how many clips it covers. With JavaScript off, every clip stays on the page under its position heading.

Changed

• Asset cache `?v=68`. `version.js` is 1.25.0.

Film: see the skills from the games land in real matches, with each clip linked to the games that train it.

Why it helps: A coach can show a move landing in a real match, then open the games that train that skill. Nothing plays until the tap.

Added

• Film at `/film`. Five competition clips, in a fixed order. Each card is a YouTube player (youtube-nocookie.com), full card width, and it does not autoplay. A tap on the player plays that clip. Watch on YouTube stays under the player.
• Each clip names the event and athletes, states the skill in one sentence, and links the games that train it.
• Linked game pages include "See it in competition" inside Show full game. The Mat stays timer-first, and Show full game stays closed.
• Film is in More, after Library.

Changed

• Asset cache `?v=67`. `version.js` is 1.24.0.
• Privacy notes that Film clips are YouTube players (youtube-nocookie.com) on the Film page and do not play until you tap them.

Start the round and put the phone down — the timer rings, keeps the screen on, and calls the role switch.

Why it helps: A coach can start the round and set the phone down. The Mat timer ticks at 0:10, then beeps and buzzes at 0:00, and holds the screen awake while it runs. Optional 3 or 5 rounds take a 30-second rest. On games that are not symmetric, Tell the room flashes Switch roles during that rest. One round stays the default.

Added

• End bell on the Mat timer and the drill timer. A generated beep and a vibration at 0:00, and a soft tick at 0:10. The speaker control sits with Reset. Mute is remembered on this device. Sound starts on the Start tap, and only if the browser can play it.
• Screen wake lock while the timer runs. Released on pause or at the end. Silent when the browser has no wake lock.
• Rounds beside Reset: 1, 3, or 5, with a 30-second rest between rounds. The clock shows REST in gold. Games that are not symmetric flash Switch roles. The choice is remembered on this device. Default is 1 round.

Changed

• The clock reads a start time, so a dark or backgrounded screen does not lose seconds. If the bell time passed while the tab was hidden, it rings on return and shows 0:00.
• Asset cache `?v=66`. `version.js` is 1.23.0.
• Favicon links use the current asset version.

See where both players start — start diagrams for three Start here games.

Why it helps: A coach can show the standing and open-guard starts before the round. First Grip Wins, Guard Retention, and Track with the Hips draw the Position on the mat: who is where, and which contact is already there. No invented grips. The timer stays first.

Added

• Start diagrams for three Start here games — First Grip Wins, Guard Retention, and Track with the Hips — on the game page and on those Start here rows. Dark mat, gold and warm-neutral figures. Works with no JavaScript.

Changed

• Asset cache `?v=65`. `version.js` is 1.22.0.
• Find reports 305 games. The index slug stays off that board.

Four new catalog games — an Enso wrist-pin half-guard rung, and three beginner leg-entanglement games — each with a free video.

Why it helps: A Developing room can start half guard with one wrist already pinned and finish under an elbow into connected hands. A Foundations room can switch outside and inside feet, then entangle one leg and the other before the partner steals inside. A Developing room can put a standing partner down with the feet and then entangle, while the standing partner clears the feet and shin-touches. Free YouTube embeds. No invented wins. Greg Souders (Standard Jiu-Jitsu) is the source. Not System JJ originals.

Added

• Wrist Pin to Connected Hands (`/game/passing/wrist-pin-to-connected-hands/`) — Developing, top-advantage, standard safety. Half guard. Top keeps a wrist pinned to the hip, gets under at least one elbow, and connects the hands. Bottom gets both feet back to the middle of the knees, or uses the knees to make top fall over. Source: Greg Souders (Standard Jiu-Jitsu), CLA Wrist Pin Guard Passing @ Enso Jiu-Jitsu Seminar. Free YouTube embed.
• Outside-Inside Entanglement Switch (`/game/leg-locks/outside-inside-entanglement-switch/`) — Foundations, role-rotating, elevated safety. Attacker hits both-feet-outside and both-feet-inside, then crosses the leg. Defender gets both feet between the attacker's knees. Beginner constraints keep the yell-tap release. Same Greg Souders beginner leg-entanglement seminar. Free YouTube embed.
• Double Entangle or Steal Inside (`/game/leg-locks/double-entangle-or-steal-inside/`) — Foundations, role-rotating, elevated safety. Attacker entangles one leg, stays attached, then entangles the other. Defender gets both feet inside before the second entanglement. Same seminar video, later start. Yell-tap release stays in the constraints.
• Put Down Then Entangle vs Shin Touch (`/game/leg-locks/put-down-then-entangle-vs-shin-touch/`) — Developing, role-rotating, elevated safety. Seated feet-inside puts the standing partner down with the feet, then entangles. Standing player gets both legs outside both feet and shin-touches from hip to shoulders, or, if they fall, both feet inside. Same seminar video. Yell-tap release stays in the constraints.

Changed

• Asset cache `?v=64`. `version.js` is 1.21.2.

Four new standing games — snap-or-knee races, over-under foot sweeps, and a lane push-out — each with a free video.

Why it helps: A Foundations room can race hands-to-mat against a knee grab, or push a partner out of a narrow lane versus a foot sweep. A Developing room can add the closed-hand win, or split an over-under: one player hunts foot contact, the other hunts a closed-hand connection. The two head-and-arm games already in the catalog now have the matching free video. No invented wins.

Added

• Hands Down or Knee Grab (`/game/standup/hands-down-or-knee-grab/`) — Foundations, symmetric, standard safety. First to three: a partner’s hands on the mat, or a grab behind the knee. Source: Greg Souders (Standard Jiu-Jitsu), seminar at Game Theory, Cologne, hosted by Hilti BJJ. Free YouTube embed.
• Three Touches or Closed Hands (`/game/standup/three-touches-or-closed-hands/`) — Developing, symmetric, standard safety. Three points the same way, or any closed-hand connection around the head, body, or leg wins outright. Same Greg Souders seminar video, later start.
• Foot Contact vs Closed Hands (`/game/standup/foot-contact-vs-closed-hands/`) — Developing, role-rotating, standard safety. Overhook player makes the partner fall while staying on their feet. Underhook player locks hands below the armpits. Source safety rules stay in the constraints. Same seminar video.
• Lane Push-Out or Foot Sweep (`/game/standup/lane-push-out-or-foot-sweep/`) — Foundations, symmetric, standard safety. Gi or no-gi. Push off the lane scores 5; a foot sweep against the lower leg scores 1; first to 15. Source: Jamie (jamielovesmartialarts). Jamie credits Cal Jones for the narrow-strip idea. Free YouTube embed.

Changed

• Capture Head and Arm and Finishing (`/game/submissions/head-and-arm-strangle/capture-head-and-arm/`, `/game/submissions/head-and-arm-strangle/finishing/`) now embed CLA Front Strangle Games @ Team Carvalho - Greg Souders (Standard Jiu-Jitsu). Rules are unchanged.
• Asset cache `?v=63`. `version.js` is 1.21.1.

Open the full game in one obvious tap — rules, wins and video sit right under the timer.

Why it helps: Expanding a game was two quiet text rows. The game page now has one full-width control under Tell the room. List cards say Open game, and the whole card is the tap.

Added

• Game pages: Show full game directly under the timer. One tap opens rules, how to win, and the reference video when the game has one. Closed on load. Works with no JavaScript. `#full` opens it when the script runs.
• Home, Find, Start here, Series, map, concept, and invariant lists, and Saved: a gold Open game → cue on the card link. Save stays its own button.

Changed

• Asset cache `?v=62`. `version.js` is 1.21.0.

Half guard: back take / sweep lists Punishing Posts.

Why it helps: That dilemma belongs to the bottom player. Punishing Posts is the half-guard game for the underhook. No-Hands Top Half Guard is a top passing game, and it no longer takes the last slot.

Changed

• `/concepts/dilemmas/half-guard-back-take-vs-sweep/` includes Punishing Posts (GG-GGM-17) and drops No-Hands Top Half Guard (GG-PAS-11). Other concept game lists stay as they were.
• `version.js` is 1.20.1. Asset cache stays `?v=61`.

Build the class with the drill that unlocks the game — add it before the round in one tap.

Why it helps: When a planned game already has Drill first pairs, Class tonight places that closed-loop drill immediately above the round. Games with no paired drill stay quiet. The pairs are the same reverse index as Mat. No new pairs.

Added

• Class tonight: Add drill before it on a plan game that already has reverse drill links. One tap inserts that drill above the game. When several are paired, the row offers up to three — the same cap as the Mat Drill first strip.

Changed

• Asset cache `?v=61`. `version.js` is 1.20.0.

Jordan half-guard duo: No-Hands Top Half Guard, Split-Control Half Guard.

Why it helps: A Foundations room can train half-guard no-hands hip control, and a Developing room can train the split-zone frame war — hips already won, upper-body frame still contested. Both pages embed the free YouTube reference. No invented wins.

Added

• No-Hands Top Half Guard (`/game/passing/no-hands-top-half-guard/`) — Foundations, top-advantage, standard safety. Top holds the chest-to-chest half-guard connection with no leg between the hips for three seconds; hands may touch the mat for base only. Bottom rebuilds a butterfly hook, a knee shield, or frees the bottom leg toward closed guard and holds it for three seconds. Source: Jordan Teaches Jiujitsu, 5 Half Guard Constraint Games for Rapid Improvement (LetsBJJ writeup). Free YouTube embed. No invented wins. Not a System JJ original.
• Split-Control Half Guard (`/game/passing/split-control-half-guard/`) — Developing, role-rotating, standard safety. Top already owns hip-to-hip and clears the upper-body frame to chest-to-chest inside the elbows. Bottom gets a leg between both players for a knee shield or foot-inside. Same Jordan source and the same free YouTube embed. Title stays Split-Control Half Guard so it is not confused with leg-entanglement 50/50. No invented wins.

Changed

• Asset cache `?v=60`. `version.js` is 1.19.0.

Privacy shows in Find and Plan More menus, same as the rest of the site.

Why it helps: Find and Class tonight are drawn by script. Privacy now sits next to Changelog there, with the same label and order as the static More menu.

Changed

• Find and Plan More menus link Privacy to `/privacy/` between Changelog and Sources.
• Asset cache `?v=59`. `version.js` is 1.18.1.

Privacy page for the App Store — what we store on device, and what we don’t.

Why it helps: A coach, an athlete, or App Store review can read what stays on the device and what we don’t collect. Privacy is one tap from the footer, and from More, next to Changelog.

Added

• `/privacy/` — Grappling Games at grappling.games. No accounts. No sale of personal data. Local storage only: role, ruleset, ladder, and the last Mat offline cache. No third-party analytics script. Contact via grappling.games. Effective 2026-09-28.

Finish this round, play the sibling — Also play stays one tap above More.

Why it helps: A coach or athlete finishes a round and opens a curated sibling without opening More. When a game already lists Also play neighbors, the mat connection strip shows up to two of those titles, after Drill first. The full list stays under More. A neighbor already shown as series Next is not repeated on the strip. Games with no Also play stay quiet. The links are the ones already on the game.

Added

• Mat connection strip: Also play links to curated neighbors already on the game. Cap of two. The full list stays under More.

Changed

• Asset cache `?v=57`. `version.js` is 1.17.0.

Drill first, then play the game that uses it — closed-loop to open-loop without leaving the page path.

Why it helps: A coach or athlete opens a drill and runs the paired game in one tap. On the mat, a game that already appears on a drill page shows Drill first — up to three drill titles — on the connection strip, after Tell the room. Games with no paired drill stay quiet. The pairs are the links already on the drill pages.

Added

• Mat connection strip: Drill first links to the drills that already list this game. Cap of three. Further drills sit inside More.
• Drill pages: the Games list stays, and the first paired game has a Run this game link to the mat.

Changed

• Asset cache `?v=56`. `version.js` is 1.16.0.

See which finishes are off-limits under ADCC or IBJJF No-Gi before you run the round.

Why it helps: A coach or athlete picks All, ADCC, or IBJJF No-Gi on Find. Under IBJJF No-Gi, games whose listed win is a heel hook — or names a heel hook as a way that win scores — show a restricted flag on the card and a short note on the mat. Straight ankle locks and ordinary submissions stay unmarked. ADCC stays permissive: nothing in the catalog is mass-flagged. The win text is unchanged.

Added

• Local ruleset control (`gg.ruleset`: All, ADCC, IBJJF No-Gi) beside the Student / Coach door on Find. Default is All, which shows no flags.
• Curated flags for eight games whose listed finish depends on a heel hook. Find shows `IBJJF: restricted` only while IBJJF No-Gi is selected. The mat keeps Start timer and Tell the room first, then one line: “IBJJF No-Gi: a listed finish is restricted.”
• “Show flagged only” sits inside the collapsed Filters body, and only after a ruleset is selected.

Changed

• Asset cache `?v=55`. `version.js` is 1.15.0.

The menu is a set of places, invariants are one of them, and the mat is cleaner until real visuals replace the stick diagrams.

Why it helps: A coach on a phone reaches Find, Map, Series, and Class tonight from the header. Invariants is the first item in More, with Library, Start here, Students, Coaches, and Sources beside it. The footer is attribution and the version, not a second copy of those links. From Invariants they open a game that trains the code. Start-position diagrams are off the mat and off Start here cards; the start line stays as text.

Added

• Primary nav: Find, Map, Series, Plan, More. More holds Invariants, Library, Start here, Students, Coaches, Saved, Train, Changelog, and Sources, plus the Student / Coach door.
• Invariants index lists each INV code with games that already train it. Open the code, or open a game.

Changed

• Footer no longer repeats Games, Series, Class tonight, Library, Changelog, and Train. Sources stays as the attribution link, with the version.
• Start-position diagrams (the TOP/BOTTOM stick figures) are not shown beside the Mat title or as Start here thumbnails. The SVG builders stay in the repo for a later replace. Map marks and series climb graphics stay.
• Asset cache `?v=54`. `version.js` is 1.14.0.

Every game has a public ID, and student and coach pages open the mat.

Why it helps: A coach can name any game in the room, including ones that never had a source code. From the student or coach page they open Find, a real mat, and Class tonight.

Added

• Catalog IDs on every game. A published `GAME-*` code stays. Every other game shows a stable `GG-` code (category short plus a number) on the mat connection strip and on Find cards. The URL slug is still the link you share. Search matches the code. The code on the strip copies.
• Students and Coaches pages open Find, Start here, a real mat (First Grip Wins), and Class tonight.

Changed

• A trailing-hyphen `GAME-*` token is not shown. Active Shot vs Sprawl keeps the published code `GAME-STD-SHOT-vs-SPRAWL`.
• Asset cache `?v=52`. `version.js` is 1.13.0.

Rules stay out of the way until needed.

Why it helps: Rules out of the way until needed. A coach can start the clock and tell the room without the position, constraints, and win walls competing for the mat. The win is one tap away. The connection strip stays a short navigation rail above More, with the invariants this game already trains.

Added

• Mat: position, objective, constraints, and the catalog win sit in a closed Rules disclosure after Tell the room and the connection strip. One tap opens them. Symmetric games still show one BOTH PLAYERS wall.

Changed

• Connection strip: tighter spacing and quieter kickers so it reads as a rail, not another rules block. A `GAME-*` code, the next series rung, the same map position, and the game’s `INV-*` chips when the catalog already lists them. The strip is omitted when none of those exist. Technique and method notes stay under More.
• Asset cache `?v=51`. `version.js` is 1.12.0.

Find tells the truth about the win, and the mat shows what to play next.

Why it helps: A coach scanning Find can read the real win before opening the mat, including on a phone that has not finished loading the catalog. On the mat, the next rung and the same position are one tap, without opening More.

Added

• Find: the first game cards are in the page HTML. The board is usable before `games-index.js` loads, and with scripts off. Search, filters, and the rest of the catalog still run once the index loads.
• Mat: a connection strip above More. A `GAME-*` code when the catalog already has one, the next game on this series when there is a next rung, and the same map position when the game is already tied to one. Invariants and technique chips stay under More.

Changed

• Find cards show the catalog win in full. The 96-character cut and the three-line clamp are gone, so a card does not end the win early.
• Asset cache `?v=49`. `version.js` is 1.11.0.

Operate stays in the chrome. The atlas lives in the Library.

Why it helps: A coach can keep Find, Series, and Class tonight in view on a phone or a desktop. Map, method, techniques, and the rest of the reference catalog are one searchable Library, not a footer full of wiki links. Source honesty stays on Sources.

Changed

• Footer is the Operate loop: Games and Start here, Series, Class tonight and Saved, then Library, Sources, Changelog, and Train. Map, method, invariants, techniques, constraints, and tools moved into the Library directory.
• Library search narrows that directory. Every section is still in the page if search does not run.
• Library, series, and constraints pages point at Sources instead of repeating the host link in the attribution line. The clickable original URL stays on Sources. Game pages still show their own source link.
• Asset cache `?v=48`. `version.js` is 1.10.0.

The mat shows the room, and a series climbs like a ladder.

Why it helps: An athlete opening a game can recognize the start or the position before the round, without hunting the map. A coach or student on a series sees the rung they are on, then marks it or adds it to class.

Added

• Mat: a compact start diagram when that game already has one. Otherwise a cream position diamond when the catalog already ties the game to a map node. Games with neither stay unmarked. Start timer, the clock, and Tell the room stay first.

Changed

• Series hub and climb pages draw the ladder as diamonds on a khaki path, with a gold halo on the current rung. Rung 1 stays the won position. Mark and Add rung to class stay on the rung list. Progress still lives in this browser.
• Asset cache `?v=47`. `version.js` is 1.9.0. Atlas chrome is unchanged.

The map is a skill tree, and Find shows games as cards.

Why it helps: A coach or student can see the position neighborhood — including on a phone — and scan a game’s level, time, and win before opening the mat.

Added

• Map: cream position diamonds, khaki transitions, a gold selected halo, and a dot grid on the dark mat. Focused neighborhood by default (`?at=`), Territory when you want the whole tree (`?view=territory`), a legend, and a you-are-here card.
• Find: game cards with up to four badges, the one-line problem, and the catalog’s top and bottom win text when it already exists. A small position mark shows when the game is tied to a map node.

Changed

• The map graph stays on screen at phone width. The position list sits behind All positions.
• The map and Find use a wider board. Mat pages keep the same reading measure.
• Asset cache `?v=46`. `version.js` is 1.8.0.

Clubb mid-range passing duo: Flatten the Shoulders, Knee Wedge to Chest Pin.

Why it helps: A Foundations long-guard room and a Developing knee-wedge room can run these tonight from Jamie Clubb's published rules, without inventing wins.

Added

• Flatten the Shoulders (`/game/passing/flatten-the-shoulders/`) — Foundations, top-advantage, standard safety. Top clears the leg frames and holds both shoulders flat for three seconds; Bottom keeps both shoulders off the mat with knees and feet in front. Source: Jamie Clubb, Mid Range Guard Passing Games for Submission Grappling. Video skipped with stamp. No invented wins.
• Knee Wedge to Chest Pin (`/game/passing/knee-wedge-to-chest-pin/`) — Developing, top-advantage, standard safety. The pass must go through a knee wedge, then chest-to-chest or knee-on-belly holds for three seconds; Bottom reinserts the frames or forces the passer out of the pocket. Same Clubb source. Video skipped with stamp. No invented wins.

Changed

• Asset cache `?v=45`. `version.js` is 1.7.1.

Copy link on Class tonight. Share tonight’s class without an account.

Why it helps: Coaches can copy a shareable class link from Class tonight build, not only after opening the full plan.

Added

• Copy link on `/sessions/build` next to Print class pack. Same `encodePlan` query as Open full plan. Button reads Copied, then restores, matching plan view.

Changed

• Asset cache `?v=44`. `version.js` is 1.7.0.

Clubb closed-guard trio: Post Removal, Sweep and Posture Battle, Headhunter.

Why it helps: A Foundations closed-guard room and a Developing neck-safe posture room can run these tonight from the source rules, without inventing wins.

Added

• The Post Removal (`/game/guard/the-post-removal/`) — Foundations, bottom-advantage, standard safety. Top may only pass by pressuring forward over the centreline; Bottom sweeps to mount without posting hands. Source: Jamie Clubb, Closed Guard Lessons in Submission Grappling. Video skipped with stamp. No invented wins.
• The Sweep and Posture Battle (`/game/guard/the-sweep-and-posture-battle/`) — Foundations, role-rotating, standard safety. Top opens closed guard and holds half guard for three seconds; Bottom sweeps with lower-body work. Same Clubb source. Video skipped with stamp.
• The Headhunter and the Posture Master (`/game/guard/the-headhunter-and-the-posture-master/`) — Developing, role-rotating, elevated safety. Top keeps the neck safe and passes; Bottom scores an armpit-to-neck connection, not a finished choke. Tap-release in the constraints. Same Clubb source. Video skipped with stamp.

Ladder progress, local: the gold rung is where you are.

Why it helps: An athlete climbing a series sees the gold rung they are on — not a Saved highlight.

Added

• Per-series local progress on the existing `gg.camp` key. Series hub and climb say You’re on rung N. No accounts.

Changed

• Current rung uses a gold mark. Marked rungs stay quiet. Mark and Add rung to class still feed Class tonight.
• Asset cache `?v=43`. `version.js` is 1.6.0.

Soft Student | Coach door. Same catalog. Different default chrome.

Why it helps: A student lands on Start here, Find, and Series. A coach lands on Class tonight, Find, and Series. Flip either way in this browser — no account.

Added

• Soft Student | Coach toggle (`gg.role`). Default student if unset. Clear and reversible. No accounts.

Changed

• Student chrome emphasizes Start here, Find, and Series; Class tonight is secondary.
• Coach chrome emphasizes Class tonight, Find, and Series; Start here is secondary.
• Catalog, Mat, and map stay the same. Asset cache `?v=42`. `version.js` is 1.5.0.

King of the Mats: a Foundations standing tile grip-boundary game from Grapplers Collective.

Why it helps: A Foundations standup room can run a grip-required tile game tonight from the source rules, without inventing wins.

Added

• King of the Mats (`/game/standup/king-of-the-mats/`) — Foundations, symmetric, standard safety. Force both of the partner's feet fully off one shared mat tile while you stay on it with an upper-body grip. Source: Grapplers Collective. Video skipped with stamp. `standup/continuous-grip-fight` is not in the catalog, so that also-play neighbor was omitted. No invented wins.

Three third-party catalog games: a side-pin figure-four / cover-hips round, plus two standing 3-second hold games.

Why it helps: A Developing pinning room and a Foundations standup room can run these tonight from the source rules, without inventing wins.

Added

• Figure-Four or Cover Hips vs Escape (`/game/pins/figure-four-or-cover-hips-vs-escape/`) — Developing, top-advantage, elevated safety. Top closes a figure-four or covers the hips; Bottom brings the legs back in front, reverses, or stands. Source: Simón Padilla, Pin Escapes Made Easy (Side Pin Game 3). Video skipped with stamp. No invented wins.
• Leg Capture Hold 3s (`/game/standup/leg-capture-hold-3s/`) — Foundations, symmetric, standard safety. Either player holds a captured leg for three seconds. Source: Jordan Teaches Jiujitsu via LetsBJJ. Reference video attached.
• Underhook Acquisition Hold 3s (`/game/standup/underhook-acquisition-hold-3s/`) — Foundations, symmetric, standard safety. Either player holds an underhook for three seconds. Same Jordan Teaches Jiujitsu reference video. `standup/continuous-grip-fight` is not in the catalog, so that also-play neighbor was omitted.

Elbow Isolation Game: a Foundations closed-guard arm-isolation round with clear Top and Bottom wins.

Why it helps: A Foundations room can run a closed-guard arm-control game tonight without inventing rules.

Added

• Elbow Isolation Game (`/game/guard/elbow-isolation-game/`) — Foundations, bottom-advantage, standard safety. Top opens or passes closed guard; Bottom traps one arm for three seconds. Source: Jamie Clubb, Clubb Chimera constraints-led guard games. Video skipped with stamp. No invented wins.

Type tonight’s class and get a catalog plan you can edit and print.

Why it helps: A coach types “45 min beginner closed guard” and gets a class from the catalog — then prints the pack — without hunting Coach desk or Class planner.

Added

• Class tonight is the user-facing coach path (`/sessions/build`, `/sessions/plan`, same `gg.plan` query params). Type what you want; Build this class picks catalog games, minutes, and sections. The plan stays editable. No invented wins.
• Saved has one Class tonight action that loads saved slugs into the planner. Series Add rung to class still lands with the rung present.
• Print class pack is a primary one-tap action on the planner and the plan view.

Changed

• Mode nav, footer, and planner chrome say Class tonight instead of Coach desk / Class planner.
• Session assets share the site cache bust (`?v=41`). `version.js` is 1.4.0.

Operate path clearer: tell the room, one timer, empty-state coaching, map grammar, series nudge.

Why it helps: A coach can say the round, start one clock, relax a dead search, and pick tonight’s ladder without hunting chrome.

Changed

• Game Mat paints one Tell the room sentence above the fold, next to Start timer / Win. Full essays stay in More. Timer-first HTML and closed More from 1.3.2 stay; `liftTimer` / `bindMore` remain belt-and-suspenders.
• Mat has one primary Start timer. The competing Start round timer link is demoted to Drill timer in the quiet actions row.
• Empty catalog search coaches what to relax — ability, safety, or clear — instead of a dead wall.
• Map and other count labels use 1 game (and the same singular elsewhere).
• Series index highlights Standing vs Seated Passing as the default “if you only climb one tonight,” aligned with Start here.

Operate works before JS finishes and Find isn’t a chip farm.

Why it helps: A coach can start the round from the first paint, and Find leads into games instead of twenty-one chips.

Fixed

• Game HTML paints Start timer and round length first, with More closed. Symmetric games emit BOTH PLAYERS in the static Mat block. `liftTimer` / `bindMore` stay in `game.js`. Game CSS/JS cache is `?v=39` so the footer reads the current `version.js`.
• Home facet chips stay collapsed until you open Filters. Start here stays collapsed.

Usability triage: search, Mat mode, map, and series climb sit in the operate path instead of under chrome.

Why it helps: Coaches can find and start a round without fighting the chrome.

Changed

• Home `/` leads with search and primary facets on mobile and desktop. Start here cards stay behind Start here. Library and Tools stay in the footer.
• Game Mat mode puts Start timer and round length first. More stays closed on every width. Symmetric games share one rules block when Top and Bottom are the same.
• Map uses the hero board on desktop and the tappable list on a phone. No horizontal clip, no third graph.
• Series hubs show Mark and Add rung to class before the climb graphic and preamble.
• One `version.js` label. `/start-here` no longer marks Find a game current. Game pages keep a path back to series, map, or Start here when that is how you arrived.

Series climb graphic on Follow a series, and visual thumbs for the eight Start here picks.

Why it helps: Coaches and students can see the ladder and start picks at a glance.

Added

• Series hub and series index climb graphic: a visual ladder of the existing rungs. Rung 1 stays the won position. Mark and Add rung to class keep the same local progress and session-builder wiring.
• `/start-here/` and home Start here thumbs/cards for the eight Foundations picks. Same start diagrams as 1.2.0, denser card layout — no invented wins or constraints.

Start diagrams on Start here, and a map hero on the positional map.

Why it helps: Students and coaches can see the start and the map without leaving the page.

Added

• `/start-here/` SVG start-position diagrams for the eight Foundations picks. Roles and contact only — no invented wins or constraints.
• `/map/` visual hero of the existing position graph. Nodes, edges, and links stay the same.

The catalog is ours — source links stay, the brand name does not.

Why it helps: Visitors see Grappling.Games. Clickable source URLs and GAME- codes stay; the borrowed name does not.

Changed

• Game attributions now read Original positional game, then the clickable title and GAME- code.
• Atlas, series, and constraints pages credit the original page without naming the other site.
• Sources hub row is Original positional games. Per-game rows keep title plus host/path.
• Curriculum voice: How this catalog is structured; “this catalog” where the old name used to teach.

Start here path: eight foundations games, then the passing ladder.

Why it helps: Beginners can start training tonight without browsing the whole catalog.

Added

• Home and Find a game Start here entry: eight curated Foundations games (standard safety; NoGi-friendly where the catalog already tags them) plus a first-series recommendation for Standing vs Seated Passing.
• Shareable `/start-here/` page with the same catalog picks. No invented games or wins.

Changed

• First major product milestone: learn → filter → run → climb.

Filter clarity: primary facets first, tags stay collapsed.

Why it helps: Coaches and students can filter the catalog without drowning in tags.

Changed

• Find a game leads with ability, asymmetry, safety/elevated, and family/position.
• Tags stay behind a control. Placeholder tags and source/meta noise stay out of the chip list.
• Filters stay folded on a phone so the catalog stays usable around 390px.

Series-first coaching path: climb a ladder, then drop a rung into class.

Why it helps: Coaches can follow a ladder and drop rungs into class planning without hunting the catalog.

Added

• Home primary CTA for Follow a series, next to Find a game and Coach desk.
• Series hub climb (rung order) with local mark progress, shared with Camp Tracker.
• Add rung to class on each rung, wired into the session builder / saved plan.

Changed

• Series pages keep the wordmark and use 44px actions so the climb works on a phone.

Mat mode on game pages: run the round from the first screen.

Why it helps: Athletes can run the game from the page without hunting for the rules.

Added

• Game detail Mat mode: Top/Bottom (or the game's roles) with Position, Objective, Constraints, Win, and an on-page Start timer.

Changed

• Chips, series ladder, Also play, and glossary/INV sit below the play block. On mobile they fold into More.
• Reference video stays just under the play block, or beside it on desktop, so the win condition is not buried.
• Save, Copy, and Print stay on the play block as secondary controls.

Optional free reference videos on game pages.

Why it helps: Coaches and students can watch a free reference for the game without leaving the page.

Added

• Optional video on a game: url, embed, title, source, and optional checked_at. embed is a YouTube id; the page builds the privacy-enhanced embed.
• Game pages with a video show a responsive player plus an Open video link. Pages without a video stay clean — no empty chrome.
• Three source-cited YouTube examples: Hold Them Down, Maintaining Control, and Finishing Mechanics.

Why it helps: The mat is easier to reach. Gold marks where you are or the class you are about to run, not a permanent Saved highlight. Mobile shows a game title before a wall of filters.

Changed

• Header is three modes — Find a game, Follow a series, Coach desk — instead of one row of peer links. Every destination stays in the footer.
• Game pages lead with roles, constraints, win, and the timer, then chips, ladder, Also play, and invariants.
• Catalog rows split ability / asymmetry / safety from secondary tags. Training Intentions is now Build a class or Open class.

Foundation already live on grappling.games.

Why it helps: Coaches and students can find games, climb series, and plan training from one place.

Added

• Full CLA catalog plus the atlas structure (method, techniques, invariants, map, library).
• Series hubs so a room can climb a ladder instead of picking games at random.
• Constraints explorer, catalog filters, drill timer, and class-pack print.

Changed

• Publish QA process is starting, so catalog copy can be checked against sources before it is trusted on the mat.
