Cars come in three fuel variants; electric, glow (internal combustion) and special. The players driving ability will place them into various categories so that they race against other cars of similar capabilities. These capabilities are classified in categories which are: Rookie, Amateur, Advanced, Semi-Pro and Pro. Tracks are also categorized depending on their difficulty to master and win. These categories are: Easy, Medium, Hard and Extreme. Cars and tracks are both unlocked through success in the game's tournament modes. Single Race allows 2-4 players on the console versions and 2-12 players on the PC version to race on the normal, single-player tracks. Within each race, competitors race to be the first to complete a preset number of laps of the circuit. To aid them in this there are a variety of lightning bolt shaped pick-ups lying around the track. Collecting one of these provides the player with a random weapon varying from oil slicks to fireworks and batteries that increase your speed for a short period of time. The worse a player is doing in the race, the more likely one of the better weapons will be obtained, and vice versa. All versions of the original game included a track editor. This works by means of a series of set modules that can be put together to form a potentially infinite number of different combinations. Modules include bridges, straights, corners, chicanes, and pipes. Each module can be adjusted in multiple ways, from height above ground level to gradient of hill and radius of corner. Pick-ups can be added afterwards to the completed track, which must then be exported before it can be played. Exported tracks can be played in Single Race or in Multi-Player.
