Gold is a currency that can be earned through regular gameplay or purchased via in-app purchases.

Diamonds, on the other hand, are a premium currency that can only be obtained through in-app purchases.

Depending on the cosmetic or customization item you're trying to unlock, you will need either Gold or Diamonds. These two currencies cannot be exchanged or converted into each other.

Gold also allows you to access premium rooms. Depending on your performance, you may receive bonus Gold after completing the game. Diamonds, meanwhile, are used to create private rooms.
