In the game, up to 3 players (4 in the NES version through use of either the NES Satellite or NES Four Score) compete against each other or the computer in racing around several top-view indoor off-road truck tracks of increasing difficulty. There are eight different tracks and 99 races altogether. All races are raced more than once. First -place results earn the player points to continue in the championship and money with which to upgrade their truck or buy more nitro. The goal is to reach the end of the season with the most money earned. Continues are available but whereas players can get extra money in the arcade version, in the home versions, the player's money is reset to 0. This is one of the first games where the player could upgrade his or her vehicle by earning points or money (although in Atari Games' Sprint series, one could upgrade their racer using wrenches), a system that is used in most arcade-style racing games today.
