The game has one main game mode, in which players can choose from any of the game's 20 tracks and attempt - singularly or with up to three additional players - to follow the on-screen dancers and instructions using the Wii Remote or up to two PlayStation Move motion controllers. Most songs feature all players performing the same moves in synch with one another, but some involve individual steps for certain players; e.g. in "My Favourite Things", one player takes on the role of Maria von Trapp, doing different steps from the others, who play as three of the von Trapp children. Different steps for different players are represented through the use of different-colored silhouettes and on-screen dancers.
Players are scored on how closely their actions follow the actions on-screen and on how many consecutive successful moves they make. The game features the same judgements from the original Just Dance. A progress bar displays the players' points throughout the song and a winner is revealed at the end of each track.
The Wii version can accommodate up to four players, while the PS3 version can accommodate up to two players.
