Stage Cards, also refereed to as YG Tickets, are items that allow the player to unlock the songs in the Special Performance Stage (the last stop in a district). At 7:00 China Time, if the player has less than three Stage Cards, the amount of these items will be refreshed to three. For instance, if the player currently has two Stage Cards, the next day they will have three. If more the number of Stage Cards owned is three or more, then it will not change.
How to Use Stage Cards
Reach the last stage in a district, and choose "Unlock Songs." This will require one Stage Ticket.
How to Purchase Stage Cards
Stage Cards can be purchased through the shop with diamonds but restricted to Platinum Members.
