How to Redeem Skull Up Codes

If you experience any issues inputting a code, check that it hasn't expired and that you have entered it correctly - keep in mind that codes are sometimes case-sensitive so it is recommended that you copy and paste the code whenever possible.

Troubleshooting Skull Up Codes

If you find the code isn't working, it could be due to any of the following reasons.

• The code may have expired: Some codes only last a few days or weeks or are tied to limited events.
• Watch your typing: Codes are sometimes case-sensitive, so copy and paste if you can. Watch out for additional spaces before or after the code.
• You might have already used the code: Skull Up codes are only good for one use per account. You can't claim the same code multiple times with the same account.
• Region locked: From time to time, codes are only available in a specific region.
• Server error: You may get a server error message when trying a code. If you do, try to redeem the code another time later.
