Just Dance 3 is a rythm/music video game in the Just Dance video game series. The player must follow the dance routine shown on-screen as accurately as possible to get a high score. The game uses the Wiimote's motion controls to track the player's movements on Wii, the PlayStation Move on PS3, and the Kinect sensor for full-body tracking on Xbox 360.

The game features over 40 songs on the original disc, such as:

• Airplanes - B.o.B featuring Hayley Williams

• Are You Gonna Go My Way? - Lenny Kravitz

Certain songs are included with a cover version, some have an unlockable Dance Mashup version, and others are specific to a store, a region or a platform. For some songs a code can be entered on the title screen to unlock an extreme version. Additional songs can be purchased as DLC, as single tracks or as song packs.
