In the game players match their skills against increasingly tougher opponents. Through a series of tournaments where you improve your skills and enhance your ranking at each step, you play against several opponents, including Venus, who possess varying levels of power, speed, and technique. As you win each match, you can reach higher and higher difficulty levels. The game also features a practice mode, where you can hone your skills before competing, and a multiplayer network ranking system, where you can upload your overall ranking and compete against other players.
