The player must react quickly and spot the moves the opponent is about to make. They need to dodge or block their attacks, before returning with attacks to either the body or the head with the left and right fists. Hitting a weak point at the right time earns stars, with the player able to save up to three stars, losing them if they are hit. When the player has one or more stars, they can perform a Star Punch which deals extra damage. Each fighter has a gauge which must be run down in order to knock the opponent down. Also the player has a heart counter that goes down if they are hit, or if their attacks are blocked. If it reaches zero, the player cannot attack. The player wins a match by either knocking out their opponent (either by a ten count or because they are unable to recover), earning a "technical knock out" by knocking them down three times in a single round, or winning by decision after three rounds have passed. If the player is hit by a knockout punch, it is possible to recover.
