The game has the player race around different race courses as four Nicktoons characters: SpongeBob SquarePants, Jimmy Neutron, Danny Phantom, and Timmy Turner. Each racer has their own unique vehicle to drive, reflective of their character, as well as unique ability, which can be used against other racers. The game includes four race tracks, one from each of the represented series: Amity Park, Bikini Bottom, Dimmsdale, and Retroville.
Winners Cup Racing features three modes for players to choose from, each with their own unique gameplay styles: Winner's Cup, the game's story mode; Quick Race, a versus mode; and Free Diving, a sandbox mode to drive around the tracks. There are also various unlockable mini games.
