As in previous installments, players must mimic the routine of an on-screen dancer to a chosen song, scoring points based on their accuracy. As with the spin-off Just Dance Now, Just Dance 2015 on the PlayStation 4 and Xbox One allows a smartphone to be used as a controller with a companion app, as an alternative to requiring a console's own motion control accessories. Motions are detected through the phone using its internal sensors.[3][4] The Chinese version features a unique tweak to the traditional karaoke-styled lyrics, in which has a glowing circle that's pulsing to the beat and is next to the highlighted lyrics. Furthermore, online features are removed in the Chinese version, except for the "Challengers" feature, which only allows competing against high scores and AI players.
