WarioWare: Smooth Moves is a party video game developed by Nintendo SPD and Intelligent Systems. The game was published by Nintendo for its Wii video game system in Japan in December 2006, and in Europe, North America, and Australia in January 2007. It was re-released on May 20, 2011 in Europe as part of the Nintendo Selects program. It is the fifth game in the WarioWare series of games, and the only game in the series to be released for the Wii (not including WarioWare D.I.Y. Showcase, another WarioWare game for the Wii). Like its predecessors, WarioWare: Smooth Moves is built around a collection of microgames that last about five seconds each, and which require that the player hold the Wii Remote in specific positions. The game offers the microgames to the player in rapid succession, by first instructing the player to hold the Wii Remote in a specific manner, and then showing them the microgame. The microgames are divided into several stages, each of which loosely connects the microgames with the help of a story.
