Under the WKO knockdown rules, a bout is decided by damage: ippon is a technique that vigorously downs the opponent for more than three seconds, waza-ari a shorter fall or a visible loss of balance. Tsukami — grabbing the dogi or a limb — and kakaekomi, hugging and holding, are fouls, and so are throws. The WKO rulebook forbids, by name, everything BJJ scores. What it trains instead is standing at short range, absorbing strikes to the body and legs without gloves, and answering them for minutes without pause.

Under the IBJJF rulebook a match is decided by control: four points for mount or back control, three for passing the guard, two for a takedown, sweep or knee on belly, each requiring three seconds of established position. Submission ends the match outright, then points, then advantages, then penalties, then the referee. An adult black-belt match runs ten minutes. The rulebook does not mention strikes at all. ADCC, the other major ruleset, names striking as illegal, awards no positive points in the first half of a match, and allows the full leg-lock game to everyone.
