More than just a retread of Super Mario Kart or Mario Kart 64, Mario Kart Super Circuit is a completely new title that combines elements of both its predecessors as well as adding new features unique to the Game Boy Advance. Single players can compete in the multi-cup Mario GP, race against the clock in Time Trial, or speed around any track in the Quick Run mode. 50cc, 100cc, and 150cc engine classes are available, with each class containing five cups, the last of which is unlocked only after earning trophies in the first four. The cast of eight playable characters consists of Mario, Luigi, Peach, Toad, Yoshi, Donkey Kong, Wario, and Bowser.
Multiplayer-only modes include Vs., in which up to four players compete in a standard race with a choice of any character and all tracks, and Battle, a four-player skirmish where the goal is to pop your opponents' balloons. Two players can also play Mario GP simultaneously. These multiplayer modes require each player to have a copy of the game, but for those not so fortunate, the Single-Pak Multiplayer mode lets up to four players link up with only one cartridge. This mode has players racing differently colored Yoshis with a choice of four tracks in a five-lap competition.
