Idle Heroes Codes (June 2026)

Idle Heroes is a fantasy idle RPG from DHGames where your squad of warriors trains and battles independently, growing stronger while you’re offline. Codes hand out free resources — Gems, Heroic Summon Scrolls, Cores of Transcendence, and more — that give your heroes a meaningful head start. We check for new codes regularly and update this list as they arrive.

Working Idle Heroes codes

Idle Heroes codes fall into two categories. Limited-time codes carry an expiry and should be redeemed as soon as possible. Permanent codes stay valid indefinitely, though every code — regardless of type — can only be claimed once per account.

Limited-time codes

Permanent codes

These codes have no expiry and are particularly useful for players just starting out. Note that IH777 requires clearing Campaign stage 3-10 before it becomes redeemable.

IH999 — 200 Heroic Summon Scrolls
IH777 — 40 Heroic Summon Scrolls (requires Campaign stage 3-10 cleared)

How to redeem Idle Heroes codes

The in-game tutorial must be completed before any code redemption is available. Some codes also require reaching a specific campaign milestone — IH777 needs stage 3-10 cleared before it unlocks for your account.

Launch Idle Heroes on your mobile device or PC.

On the main screen, tap the Cool Events button — it has a purple gift icon and sits in the top-left corner of the screen.

Paste your chosen code into the entry field and tap the Exchange button to claim the reward.

A confirmation message appears on screen once the code is accepted. Head to your in-game mailbox to collect the rewards — they are not added to your inventory automatically.

Note: All codes are case-sensitive. Copy and paste each one directly from the list above rather than typing manually to avoid entry errors.

Where to find new Idle Heroes codes

DHGames releases new codes through the game’s official social channels, typically around in-game updates, the start of a new month, and special events such as the game’s anniversary. The official Idle Heroes Discord server is one of the fastest places to catch codes the moment they go live. The game’s Facebook page, Reddit community, and Instagram account also carry new codes around major milestones and seasonal celebrations.
