Mario Kart Wii features multiple game modes: Grand Prix, Time Trials, Versus, and Battle. All modes support single-player gameplay; Versus and Battle support local multiplayer for up to four players, with or without computer-controlled players. In Grand Prix, the player participates in four three-lap races from one of eight cups against eleven opponents. The player is awarded points at the end of each race based on their ranking. The total number of points collected determines the player's overall rank. Versus mode is similar to Grand Prix, but the presented courses and items may configurable. In Time Trials, the player must quickly complete the race in the fastest time possible— there are no opponents or items except for three Mushrooms given at the start of each race. The player can compete against a ghost character, which mimics a player's movements from an earlier race. Ghost data can be saved in the Wii console memory.
Arcade Machine Mario Kart Arcade GP 2 was released to arcades in 2007/2008. It features the same playable characters as its predecessor, but also adds Waluigi and crosses over Mametchi from the Tamagotchi series (the former being previously playable in the main Mario Kart series, and the latter making their only Mario appearance overall). This game also introduces unique karts for each character, as in the main games from Mario Kart DS onward; more items unseen in the normal installments; and color commentary, which can be toggled on or off at any time prior to starting the race.
