The Wii U is a home console made by Nintendo. It is the successor to the Wii, and is backwards compatible with Wii games, except for select games that require the use of the GameCube Controller ports that are present on earlier Wii models. as the GameCube Controller Adapter used to connect GameCube controllers and other GameCube peripherals is only supported in Super Smash Bros. for Wii U. The Wii U can also utilize Wii controllers and accessories such as the Wii Remote, Nunchuck, and Classic Controller (including the Classic Controller Pro) alongside its main controller the Wii U Gamepad, and the secondary Wii U Pro Controller. Certain games on the Wii U require the use of Wii Remotes such as Wii Sports Club, Nintendo Land (for certain minigames), and Mario Party 10.
The Wii U sold 13.56 million units worldwide, making it both Nintendo's least successful home console to date after the Nintendo GameCube and a commercial failure. Its successor, the Nintendo Switch, outsold the Wii U's lifetime sales only 9 months after its release.
