Deuce Hit! (Tennis) is a three-dimensional sports game in which the player competes against an AI system or other global online players in single-court and tournament play. Via a stickman-style avatar, the player must achieve two points per tennis match to reach the next round and then the semi-finals and the championship final match. To win, they must use their knowledge of tennis, listen to and trust their intuition, and use precise coordination and timing.
