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, among other factors, determines the player's overall rank.
Versus mode is similar to Grand Prix, but the presented courses and items are 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.

Mario Kart Wii's Battle mode is similar to that seen in previous installments in which players drive around an enclosed arena and attack each other using items.
The players are divided into two teams, red and blue, and teammates cannot harm each other with their items.
There are two variants of Battle mode available: Balloon Battle and Coin Runners.
In Balloon Battle, each player's kart has three attached balloons.
A player gains a point each time they pop or steal a balloon belonging to an opposing team player but loses a point each time they lose all balloons.
In Coin Runners, the players collect coins scattered throughout the arena and attack opposing team members to make them drop coins.
The team that has accumulated the most points or coins total when the three-minute time limit expires wins.

Mario Kart Wii supported online play via Nintendo Wi-Fi Connection until its discontinuation on May 20, 2014.
Versus and Battle modes were available and supported up to twelve participants, and up to two players could connect and play from the same Wii console.
Players could compete against random players from within the same region or from any continent, or could compete only against players registered as friends.
At the end of each race or match, each player's VR (versus rating) or BR (battle rating) would change based on their final ranking.
Mario Kart Wii featured the "Mario Kart Channel", which was available as an optionally selectable channel on the Wii Menu, that presented current regional or worldwide rankings for Time Trials, and the option of sending or receiving ghost data via WiiConnect24 (it is no longer supported and does not function as of June 28, 2013).
 Mario Kart Channel also offered worldwide tournaments from Nintendo, which were modified courses that sometimes had special objectives.
There were two tournaments hosted each month.
Despite the Wi-Fi connections discontinuation, fans have created numerous private servers to continue playing online, the most notable being "Wiimmfi" which was launched on May 10, 2014, ten days before the shutdown of the official servers.
