Skull Up Codes (September 2026)

How to redeem codes in Skull Up

You need to clear the opening tutorial battles before the redeem option shows up, so don’t skip that part or you won’t have anywhere to enter these codes yet. Once you’re past it, here’s how to claim your rewards.

Launch Skull Up and log in to your account.

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

Select Redeem Code from the menu that pops up.

Type or paste a code exactly as it’s written, matching the capitalization, into the “Enter a redeem code” field, then tap Claim.

You’ll know it worked when your rewards show up in your inventory right away and a confirmation prompt pops up on screen. If nothing appears, double-check the spelling and capitalization before trying again.

How to get more Skull Up codes

New codes typically show up around in-game events, milestones, or bug-fix updates, and you’ll usually spot them through official in-game announcements and the developer’s own social channels. Checking back after a patch or a themed event is your best bet for catching a fresh one before it expires.

Are Skull Up codes free?

Yes, every code is free to redeem and only requires an account that has finished the tutorial battles.

Why didn’t my code work?

Codes are case-sensitive, so a mistyped letter or extra space will cause the redemption to fail even if the code is still active.

Keep this page bookmarked and run through the list whenever you log in, since a few extra diamonds and a free Wraith Pact add up fast when you’re still building your roster.
