As in previous installments, players must mimic the routine of an on-screen dancer to a chosen song, scoring points based on their accuracy. For input, the game supports either the respective motion controller system for a particular console platform, or a smartphone with the game's companion mobile app.[2]
The "Dance Party" mode has been renamed to the "Just Dance" mode, players can now have the ability to search for a song using the menu. The "Superstar" rank has been added, in which it's achievable at 11,000 points. A new "Just Dance Machine" mode was added on current-generation console and PC versions, in which players must dance through routines of different styles to help recharge an alien spaceship.[2][3][4] Each session contains five routines, with "Cosmic Rounds" popping up randomly. The story of this mode follows two aliens that are dancing on their ship. All of a sudden, their battery is running low. To recharge its battery, the aliens traveled to Earth and abduct human dancers known as "coaches" to recharge its battery by dancing. In the ending, the battery was charged and the aliens leave Earth as they keep dancing. But unfortantly, their battery is running low once again.
