While playing, there are several parameters to consider. A health meter recharges when the boxer dodges hits for some time. Punches need to be thrown strategically, as an energy bar determines their effectiveness. The amount of punches also affects whether a boxer will get up when knocked down. A round timer and knockdown lights are also displayed. At certain times, a power-up indicator becomes available, allowing a boxer to charge a heavy punch, but the opponent has time to react.
