Why Aren't My Siberium Codes Working?

Promo codes expire fast and have specific rules. Here's why your Siberium code might be throwing an error:

• The code has expired. For Siberium, event codes and milestone codes tend to expire quickly — sometimes within hours. Try redeeming new codes as soon as they appear on our list to avoid missing out.
• Double-check for typos. Codes aren’t case-sensitive here, but a single wrong character will still cause a failure. Copy and paste codes like "RQ58Z3NT" from our list rather than typing manually.
• Already redeemed. Each code can only be used once per account. If you’ve already claimed it, it won’t work again — even after reinstalling or updating.
• Platform or region mismatch. This game is available on iOS, Android. Some codes only work on a specific platform or region — make sure the code is intended for yours.
• Check your in-game mail. Some rewards are sent to your mailbox rather than added to your account instantly. Look for a notification icon or mail tab after redeeming codes like "RQ58Z3NT".
• Restart the game. Idle and incremental games sometimes need a full restart for code rewards to show up. Close the app completely, reopen it, and check your balance.
