How to redeem Skull Up codes
Complete the tutorial first, since the redeem menu only unlocks after you finish the opening battles. Once that’s done, follow these steps inside the game.
Type or paste a code exactly as it appears, including capitalization, into the “Enter a redeem code” field.
Tap Claim. Rewards land directly in your inventory, and a confirmation prompt appears once the code goes through.
