Idle Heroes hands out redeem codes that convert into Heroic Summon Scrolls, Gems, and other account boosts without spending real money. New players and long-time guild leaders alike can punch these into the in-game exchange screen to pad out their roster before the next big summon push.
Working Idle Heroes codes
Codes fall into two buckets in Idle Heroes: limited-time drops tied to a specific month or event, and permanent codes that never expire but only redeem once per account.

Note: IH999 and IH777 are permanent codes meant mainly for new accounts, and IH777 won’t redeem until the tutorial has been completed and Campaign stage 3-10 cleared.
How to redeem codes in Idle Heroes
Redemption happens entirely inside the game and takes less than a minute once the menu is open. The tutorial must be finished first, since the exchange screen stays locked for brand-new accounts.
Expired Idle Heroes codes
These codes stopped granting rewards and won’t process if entered.

Each code redeems once per account, and rewards land in the mailbox rather than being applied instantly to your hero roster or resource totals, so check there if nothing seems to change on the main screen right away.
