Heavyweight Championship Boxing is a boxing game with six athletes, all with different strengths and disadvantages. After choosing one of them, the goal is to defeat the rest of them for the title. However, the player can re-distribute the points of the athlete on abilities such as speed, strength and health. During a match the goal is to bring the opponent's health down by performing moves like uppercuts or normal punches.
The gameplay involves controlling your chosen boxer in one- and two-round matches against other opponents. The objective is to knock out your opponent or win by points. You can switch between different fighting styles, such as a strong puncher or an agile boxer. Each round brings new challenges and opportunities to exploit your opponent's weaknesses.
