  • Patent number: 4491324
    Abstract: An electronic fighting sport game apparatus includes stamina data memory sections which store initial and current stamina data of fighters or boxers. A stamina data arithmetic section reads out the current stamina data of the attacked boxer from the stamina data memory section when one of the boxers delivers a clean punch. The readout stamina data is decreased by a predetermined amount. The decreased stamina data is stored again in the stamina data memory section. The action or movement of the boxers is performed in accordance with stamina data. The winner or loser is judged by determining whether the final stamina data of a boxer is larger or smaller than that of his opponent.
