Idle Heroes Codes (July 2026): Free Diamonds, Summon Scrolls, and More

Update: Added new Idle Heroes codes on July 29, 2026

Idle Heroes is celebrating its 10th anniversary, and DHGames has been releasing a steady stream of redeem codes to mark the occasion. These codes are one of the easiest ways to claim free Diamonds, Gems, Heroic Summon Scrolls, Cores of Transcendence, and other valuable resources without spending real money. Several of the latest codes are tied directly to the anniversary celebration rather than the game’s usual seasonal promotions.

The downside is that most Idle Heroes codes don’t stay active for long. DHGames typically retires them after a few weeks or limits them to a short redemption window, meaning a code that works today could stop working tomorrow. That’s why it’s worth redeeming every active code as soon as possible.

Below, you’ll find every Idle Heroes code confirmed to be working, along with instructions on how to redeem them before they expire.

All Working Idle Heroes Codes

Among these, IH999 and IH777 are considered permanent codes and have remained active for years, making them excellent starting points for new or returning players.

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.

1. Launch Idle Heroes and log in to your account.
2. Tap the Cool Events icon near the top-right corner of the main screen.
3. Open the Exchange Gifts tab.
4. Copy and paste one of the active codes into the redemption box.
5. Tap Exchange.
6. 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.

Expired Idle Heroes Codes

Like most live-service mobile games, Idle Heroes regularly retires older redemption codes. If you find one on an outdated guide, there’s a good chance it no longer works.

The following codes have been confirmed as expired:

• IH24XMAS
• DRGNBOAT2025
• SEPT9LUTZ
• ENJOY11IH
• AKUJAN26
• JAN26BOOST
• BREEZEDROP26
• REALGIFTAPR
• BLAZINGIHMAY
• IDLEMAY1ST
• MJT26MAYT

Several other anniversary-era codes, including IH2025MOON, GIFT10LUTZ, SUMMER8IH, and LUCKYINJULY, still appear on older code trackers. However, they could no longer be consistently verified across multiple sources, so they’re no longer included in the active list above.

If you’re ever unsure whether a code still works, it’s still worth giving it a try. DHGames occasionally leaves promotional codes active longer than expected.

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.

Wrapping Up

With Idle Heroes’ 10th Anniversary celebration still underway, it’s a good time to redeem every active code while they’re available. Even if a code only grants a handful of Diamonds or Heroic Summon Scrolls, the rewards add up over time and can make summoning new heroes or progressing through events much easier.

Because anniversary codes tend to have shorter redemption windows than evergreen ones like IH999 and IH777, it’s worth claiming them as soon as possible. We’ll continue updating this guide whenever DHGames releases additional codes, so check back regularly for the latest freebies.
