Skull Up codes (March 2026) - Bolster your undead pals
Even if your army is undead, growing it isn't easy. That's where Skull Up codes can help, netting you extra diamonds and Summon Cards.
Skull Up is an idle RPG where you summon the undead to fight alongside you. Your goal? To become the Skull King! With an army of over 60 Skellies to recruit and a strong team to form, nothing is impossible.
Since this is an idle game, there are a lot of rewards waiting for you every time you launch Skull Up, and you just need to grab them in order to upgrade your soldiers. The resources can be fully refunded, so you can experiment freely.
If you're looking for codes, you're in the right place. Below, you'll find a complete list of active Skull Up codes, as well as instructions on how to redeem them.
