The concept of the game is the same as the original Just Dance. Requiring only one Wii Remote per player, up to four people can play at a time, as they follow on-screen choreographed moves set to classic dance tracks. There are four new dance modes. In `Just Dance Mode`, players can get together and dance for as long as they want, just for the fun of it. Other options include `Non-Stop Shuffle` for a non-stopping gameplay, and `Medleys`, in which short pieces of 5 songs are mixed.
The second new mode, `Duets` allows players to dance together, and in the process forces them to pay more attention to the players around them instead of simply following on-screen prompts.
`Dance Battle Mode` is a team mode that features up to 8-player support.The individual scores are the basis of the overall team scores.
Lastly is `Just Sweat Mode`, which is an exercise mode that allows players to measure the energy they expend while dancing as well as set objectives to be met during their dance sessions.
