Skull Up codes (March 2026) for Diamonds, Summon Cards, Souls, and more

Skull Up codes will give you a significant advantage in this mobile role-playing adventure, where you defeat enemies then convert them into undead soldiers to fight at your side. There's also an RNG element involved, where you spend Summon Cards to receive a random selection of Skellies to bolster you ranks, and some of the promos listed here will immediately give you more chances to try you luck with this. If you're ready to build your skeletal army, then here are all of the redeem codes for Skull Up.

How to redeem Skull Up codes

To redeem Skull Up codes, you need to complete the initial tutorial that involves being lead through various fights, until the screen opens up and you can select all of the available options. Tap the profile icon in the top left corner to open the Profile menu, then choose the Redeem Code option at the bottom of the screen. This will take you to the Use Redeem Code screen, where you can type each promo into the Enter a redeem code text box before hitting Claim to receive your rewards. This process works on both iOS and Android, so you don't need to visit an external website to claim them.
