Why Aren't My Idle Heroes Codes Working?

If you're having trouble claiming rewards, check these common issues related to Idle Heroes codes:

• The code has expired. For Idle Heroes, many codes have a short shelf life, sometimes lasting only a day or two. If you’re seeing an error, the code may have already been deactivated. Check the status tag next to each code on our list.
• Codes are case-sensitive. This game enforces exact capitalization — "JANBARRY2026" won’t work if typed as "janbarry2026". Copy the code directly from our list to avoid mistakes.
• 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.
• Wrong redemption screen. Codes need to be entered at a specific location: Settings -> Exchange Gift. Trying to redeem from a different menu or screen won’t work.
• Check your in-game mail. If nothing happened after entering "JANBARRY2026", don’t panic. Open your in-game mail or gift box — that’s where rewards are usually deposited.
• 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.
