How to redeem codes in Skull Up

Complete the game’s tutorial first, since the redeem option only appears once the main menu unlocks. After that, redeeming a code takes only a few taps.

Launch Skull Up on your device and log in to your account.

Tap your profile picture in the top left corner of the screen.

Select the Redeem Code option from the menu that opens.

Enter one of the active codes into the “Enter a redeem code” field. Codes are case-sensitive, so type them exactly as shown, including capitalization.

Press Claim to receive your rewards. A successful redemption delivers the diamonds, summon cards, or other items straight to your inventory, and you can confirm this by checking your resource totals right after claiming.

When new Skull Up codes appear

New codes for Skull Up typically arrive alongside game updates, special events, or milestone celebrations. Redeeming a code soon after it appears matters, since some carry limited uses or get replaced once a promotion ends.

Bookmark this list and check back periodically, especially around update announcements, to catch new codes while they’re still active.
