It allows you to automatically play a Solo Show.
Using Auto-Play costs at least one Bonus Energy.
The Bonus Energy cost is between 1 and 5.
During certain events, the cost can be between 1 and 10.
In addition, there are two Auto-Play modes that allows you to play Shows continuously without pause. You can either set Auto-Play to run until your Bonus Energy runs out, or set a limit of however many songs you'd like to play via Auto-Play.
If you choose to set a limit for how many songs you'd like to play via Auto-Play, you can also set your Bonus Energy Drinks or Crystals to be used automatically to restore your Bonus Energy should it run out partway.
If you'd like to either pause or stop Auto-Play, tap the pause button in the top right hand corner.
*The amount of Bonus Energy that will be used in Auto-Play is based on the amount you have set in Bonus Energy Settings.
*Rank up screens will be skipped during continuous Auto-Play.
