The focus of the game is racing one of a selection of cars through various themed tracks. Secret tracks can be accessed by winning and new cars can be used by finding the 'new car' bonuses hidden in each stage.
As seen in the hint screens, using the controller to perform various stunts from jumping off points gains 'turbos' which allow short bursts of speed. The car in use will take damage based on running into obstacles or other players. Icons found around the track give differing performance enhancements.
The game requires a memory card in order to save progress.
