UC can be used for supported in-game purchases such as Royale Pass and cosmetic items. The exact top-up flow depends on the product and region: a direct delivery item generally uses player information, while a redeemable voucher uses a code. Resellers should check the offered package and required input schema rather than assume every UC listing is equivalent.
Key facts
- UC stands for Unknown Cash
