Idle Horizons is a pixel-art idle RPG where you deploy heroes against waves of enemies. Like most gacha games, it gives players redeemable codes that grant Gems for summoning heroes, Summon Scrolls to pull them, and — in one case — an exclusive Legendary hero, Ignis. Redeeming these codes right at the start of your playthrough can set up your entire run, so here is everything currently available, plus what has already expired.
The Code Right Now: E0DF429C5D
There is currently one working code:
- E0DF429C5D — expires October 01st
Redeem it as soon as possible. The game rotates codes on a weekly schedule, so this one will stop working once the next one drops.

The takeaway: check back weekly. If you miss a code, it is gone for good.
Permanent and Promo Codes With Known Rewards
Some codes do not follow the weekly rotation and grant specific reward packages:
- FBC25 — 1000 Gems, 3 Challenge Tickets, 15 Summon Scrolls, 3 Arena Tickets
- TIKTOK25 — 1000 Gems, 3 Challenge Tickets, 15 Summon Scrolls, 3 Arena Tickets
- JOINDISCORD — 250k Gold, 500 Gems, 10 Summon Scrolls, 3 Challenge Tickets, 3 Arena Tickets
- PLEASE — 1000 Gems, 3 Challenge Tickets, 15 Summon Scrolls, 3 Arena Tickets
- GULLIBLE — 1000 Gems, 3 Challenge Tickets, 15 Summon Scrolls, 3 Arena Tickets
- IGNISNOW — 20 Ignis Hero Shards
Others have been released without publicly listed reward details: RUSH0925, GCPOUTAGE0625 (redeemable only on some accounts), ARENASHOP00, SK02625, RC0225, NEWYR2025, and LAG5PROMO.
The most valuable of these is IGNISNOW. Collecting 20 Ignis Hero Shards moves you toward an exclusive Legendary hero you cannot easily get elsewhere, and since the gacha in Idle Horizons is generous with dupes for powering up heroes, stacking shards early compounds your advantage.
How to Redeem Codes
You cannot redeem codes immediately — the Shop unlocks after you reach story level 10. Once you are there:
- Open the Shop.
- Scroll all the way down to the Misc. section.
- Tap on Code.
- Type in your code and hit Confirm.
If a Code Is Not Working
Most failed redemptions come down to typing errors. The codes are case-sensitive and packed with zeros versus the letter "o", which makes manual entry unreliable. Copy and paste the codes directly rather than typing them out — this solves the vast majority of "invalid code" problems.
Why Bother With Codes at All
In a gacha idle RPG, early resources snowball. Gems translate directly into more hero summons, and more summons mean more dupes, which power up your roster. Grabbing the weekly code plus the permanent codes above at the start of your account is the single cheapest way to get ahead without spending anything. If you enjoy this genre, similar code lists exist for other free-to-play titles like Era of Warfare, and Jujutsu Infinite codes are worth checking if anime-style games are more your speed.
