Just Dance is a series of games by Ubisoft, which involve dancing to various songs using the Wii Remote or a smartphone. The main gameplay of the franchise is to try to copy what the on-screen dancer is dancing, with a Wii Remote or Smartphone judging the player on their performance. The Wii Remote or Smartphone has to be held in the player's right hand for proper scoring. While gameplay was almost the same in all games, some new features were added to the series. (Duets, Trios, Dance Crews etc.)
