Skull Up Codes (August 2026)

Skull Up hands out diamonds, summon cards, and forge crystals through codes the developers drop from time to time. Redeeming them takes just a minute once you know where the redeem option lives, and you can grab every reward below before it expires.

Working Skull Up Codes

Type these in exactly as shown, since Skull Up codes are case-sensitive.

Note: codes marked “Free rewards” don’t list a fixed item breakdown, so check your inventory right after claiming to see exactly what you picked up.

How to redeem codes in Skull Up

You need to finish the game’s tutorial before you can redeem anything, because the redeem option only shows up after the main menu unlocks. Once you’re past that, claiming a code takes just a few taps.

Are Skull Up codes free?

Yes. Every code listed here is free to redeem and doesn’t require any purchase.

Why didn’t my Skull Up code work?

Double-check the spelling and capitalization first, since codes are case-sensitive. If it still fails, the code has likely expired.

Redeeming codes only takes a few seconds once your account is past the tutorial, so run through the working list above and grab whatever’s still active before it’s gone.
