Idle Heroes codes (August 2025)

With the Rate Summons and Diamonds redeem codes provided in Idle Heroes, you can create a strong team of undefeatable warriors to dominate the mobile game.

DH Games’ mobile RPG, Idle Heroes, is all about battling fearsome villains and putting together tough team combinations. Summon Scrolls lets you add new heroes to your squad, and you can get plenty of them via codes.

Below, you’ll find all the latest details on every code that’s not expired yet, and steps on how you can get them in game.

Active codes in Idle Heroes

There are currently two active codes that can be redeemed in Idle Heroes as of August 1, 2025. We’ve manually checked these codes and can confirm them to be working at the time of writing:

Code	Reward
IH999	x60 Summon Scrolls
IH777 (New players only)	x50 Summon Scrolls

A set of new codes were actually released in June for a short time to commemorate the game’s anniversary. However, these were only active for a short time and now have already expired.

It’s also worth noting that while the ‘IH777’ code is currently active, you’ll need to clear Campaign 3-10 to be able to redeem it.

How to redeem codes

Before redeeming codes, you’ll need to complete the tutorial or at least complete Campaign 1-4, which doesn’t take long as long as you speed up the battles. Once you’ve done that, follow these simple steps to claim your rewards:

• Open Idle Heroes, then go to the ‘Cool Events’ menu located at the top-right of the screen.
• A window will appear. Select the ‘Cool Events‘ tab as shown in the image below.

• On the left-hand side, you’ll see the ‘Exchange gifts‘ tab, which you’ll likely already be on.
• Enter any of the above codes into the box and click ‘Exchange.’
• Head over to your in-game mailbox and collect your reward.

Certain codes might require you to complete certain stages alongside the tutorial. When you try to redeem them, you’ll be notified of what stages you need to beat to get the rewards.

What are Idle Heroes codes used for?
