Mario Kart Wii/Wi-Fi

Mario Kart Wii uses Nintendo Wi-Fi connection to support a wide amount of options online, including leaderboards, downloading and uploading ghost data, friends' status, records, and multiplayer modes, both Battle and Versus.

All online options can be viewed from the Mario Kart Wii channel without accessing the game.

The tournament mode can by accessed through Wi-Fi.

A unique feature to the Mario Kart Wii channel is the notification of messages and challenges through a blue light on your console. If you choose to accept a challenge, you usually have to play with specific conditions, for example not being able to use the GameCube controller.
