The gameplay of Just Dance 2 remains similar to the original; while holding a Wii Remote in their hand, players must mimic the routine of an on-screen dancer to a chosen song. Players are judged based on their accuracy, scoring points.[1]
Selected songs offer "Duet" modes, which feature choreography designed for two players.[1] A new mode known as "Dance Battle" was also introduced; it is a team-based mode in which players compete across a series of songs and minigames to earn points for their team. The mode can be played with up to eight players, divided into two teams of four.[1]
A new exercise-focused gameplay mode known as "Just Sweat" was also added; the mode is designed to serve as a daily exercise regiment, allowing players to select an intensity-based selection of songs. Activity in Just Sweat mode is gauged using "sweat points"
