Update: Added new Idle Heroes codes on September 1, 2026
Idle Heroes codes are the easiest way to claim free Diamonds, Gems, Heroic Summon Scrolls, and Cores of Transcendence without spending real money. DHGames releases them around anniversaries, updates, and holiday events, and the game recently marked its 10th anniversary with a run of celebration codes.
The catch is that most of them do not last. DHGames typically retires codes after a few weeks, often without announcing an expiry date, so a code that works today can quietly stop working tomorrow. Redeem anything active as soon as you find it.
Below is every code confirmed working right now, along with how to redeem it.
All Working Idle Heroes Codes
| Code | Reward |
|---|---|
| IH8BONUS | Free rewards (Valid until August 31, 2026) |
| BARRY7GIFT | 60 Heroic Summon Scrolls (evergreen) |
| AKU7IHGIFT | 50 Heroic Summon Scrolls (new players only) |
| HOTJULY7IH | Free rewards (expires July 31, 2026) |
| IH999 | Exclusive 10th Anniversary rewards |
| IH777 | Exclusive 10th Anniversary rewards |
Most of the remaining codes are part of the game’s ongoing 10th Anniversary celebration. While DHGames has confirmed they’re active, the developer hasn’t officially detailed the exact contents of every reward bundle. Based on previous anniversary giveaways, expect a combination of Diamonds, Gems, Heroic Summon Scrolls, Cores of Transcendence, and other upgrade materials.
How to Redeem Idle Heroes Codes
Redeeming an Idle Heroes code only takes a few seconds once you know where to find the menu.
- Launch Idle Heroes and log in to your account.
- Tap the Cool Events icon near the top-right corner of the main screen.
- Open the Exchange Gifts tab.
- Copy and paste one of the active codes into the redemption box.
- Tap Exchange.
- Open your in-game mailbox to collect the rewards.
Unlike some mobile games, Idle Heroes doesn’t automatically add redeemed rewards to your inventory. Everything is delivered through your mailbox, so don’t forget to claim it before closing the game.
Also keep in mind that most modern redemption codes only work after you’ve completed the game’s introductory tutorial. If you’re using a brand-new account, you may need to play for a few minutes before the redemption option becomes available.

Why Isn’t My Idle Heroes Code Working?
If an Idle Heroes code doesn’t redeem successfully, it’s usually caused by one of a few common issues rather than a problem with the game itself.
The Code Was Entered Incorrectly
Idle Heroes codes are case-sensitive, so even a small typo or an extra space can cause a valid code to fail.
Copying and pasting the code directly is the easiest way to avoid mistakes.
You’ve Already Claimed It
Nearly every Idle Heroes code is limited to one redemption per account.
If you’ve already redeemed a code, entering it again simply returns an error without granting additional rewards.
The Code Has Expired
This is the most common reason.
DHGames rarely announces expiration dates ahead of time, so promotional codes often disappear without warning after an event ends.
The Code Is Region-Specific
Some promotional codes are distributed through regional campaigns or specific social media channels.
For example, a code shared during a Facebook event may not always work for every player worldwide.
If none of these situations apply, it’s worth checking whether the developer has released a newer replacement code.
Where to Find New Idle Heroes Codes
DHGames doesn’t follow a fixed schedule for releasing redemption codes.
Instead, new codes usually appear during:
- Anniversary celebrations
- Major game updates
- Holiday events
- Livestreams
- Community milestones
- Social media promotions
The fastest places to find new codes are the official Idle Heroes Discord server and DHGames’ social media channels. Since many promotional codes expire quickly, checking these platforms regularly can help you claim rewards before they’re gone.
If you don’t want to keep searching yourself, bookmark this page. We’ll update it whenever DHGames releases new Idle Heroes codes.
Wrapping Up
The reliable evergreen codes, IH999 and IH777, are worth redeeming immediately if you have not already, particularly on a newer account where both should work. Everything else in Idle Heroes rotates fast enough that the only real strategy is checking often and redeeming the moment you spot something.
Even a handful of Diamonds or Summon Scrolls compounds over time, making summoning and event progression noticeably easier than grinding alone.
Idle Heroes codes are promotional redemption codes released by DHGames that reward players with free in-game items such as Diamonds, Gems, Heroic Summon Scrolls, Cores of Transcendence, and other resources.
There isn’t a fixed schedule. DHGames typically releases new codes during major updates, anniversary celebrations, holiday events, and community promotions.
No. Almost every Idle Heroes code is limited to one redemption per account. Once you’ve claimed it, the same code can’t be used again on that account.
