The Japanese version of switch can dance to rainbow beats, as long as the game the player buys is the Chinese version of the game. Just Dance Rainbow Beats is only available on the Chinese Switch.
Players can collaborate with friends on rainbow beats in cooperative mode for more fun. The cooperative mode's rainbow beats bring players together to add up their scores to dominate the dance floor. The higher the player's points in Rainbow Beat, the more props can be unlocked.
Note for Just Dance players.
Players should pay attention when playing Just Dance. The switch version of Just Dance will enter the novice guide at the beginning of the game. Beginner players only need to remove the joycon controller and hold it in their hands, and Just follow the onscreen instructions to dance. There is no need to switch the left and right directions. If the screen is left and the player is left, the player will be prompted on the screen for the next action.
