The game itself features three different modes: Doubles mode, World Circuit mode, and Singles mode, in which the player competes against a human or chosen computer opponent.[2][3] In doubles mode, the player and a human teammate can face the CPU. Said-players can each pair with a CPU opponent, or one player can pair with a CPU opponent to face two other computer opponents. Circuit mode is the most unlike the other modes and featuring a wide range of sequential tours the player can choose to battle through each to earn ranking points, with aim to finish number one in the rankings. There are four minor tournaments and four major tournaments, each taking place on one of three surfaces that each have different effects on how the ball bounces; the tournaments are based on real-life counterparts and include nearly every world tournament in existence at that current time.
