Skull Up Codes (July 2026)

Skull Up is a mobile idle RPG where players assemble and command an army of skeleton warriors. The core loop revolves around summoning new Skellies, upgrading them with gathered resources, and pushing through combat stages of rising difficulty on the road to becoming the Skull King. Codes hand out free Diamonds, Summon Cards, AFK resource boosts, crafting materials, and more — a straightforward way to accelerate your roster without spending in-game currency.

How to enter a Skull Up code

The redemption menu only becomes accessible after completing the tutorial, so finish that first before attempting to claim any codes.

Open Skull Up on your device and sign in to your account.

Tap your profile picture in the top-left corner of the screen to open the account menu.

Select the Redeem Code option from the menu.

Type one of the active codes into the “Enter a redeem code” field. Pay close attention to capitalization, since codes are case-sensitive — a single wrong letter will cause the code to fail.

Tap the Claim button. Rewards arrive in your account immediately, and a confirmation message will appear on screen.
