is a leg entanglement position in which the attacker has captured both of the opponent’s legs and crossed them — creating a Z-shaped or figure-four-style leg configuration. The crossed legs are controlled by the attacker’s own legs and body position, leaving the opponent’s legs trapped and the knees and ankles simultaneously vulnerable.
The position earns its colloquial name from the submission accessibility it creates: with both legs crossed and controlled, the attacker has access to heel hooks on both legs, toe holds, and other leg submissions without needing to re-enter or change entanglement positions. The opponent has both legs under structural threat simultaneously — defending one often exposes the other.
The terminology is inconsistent across the community: this position is called “Game Over” in 10th Planet contexts, “Z-Lock” in other submission wrestling contexts, “Leg Knot” in some catch-wrestling-influenced systems, and “Sambo Knot” in sambo-derived systems. This site uses “Game Over” as the canonical name but recognises all alternatives.
is distinct from 50/50 (where each leg is in the other’s entanglement, creating mutual control) and from single leg X (which controls only one leg). Game Over controls both legs simultaneously with the crossed configuration as the distinguishing element.
Elevated RiskGame Over is an elevated risk technique. The Game Over position provides immediate heel hook access to both legs. Heel hooks attack the ACL, PCL, and knee ligament complex through rotation — the damage can occur before acute pain registers proportionately. With both legs under simultaneous threat, the opponent may not know which leg is being attacked first, which delays their tap decision. Both players must have explicit tap-early agreements specifically for heel hook applications from this position. The position's design is inherently fast-to-submission. Serious injury can occur fast — simultaneous bilateral heel hook access with limited defensive options.
