Idle Horizons codes (August 2025) - Free gems and summons

As someone who absolutely loves pixelated games, I loved this fun little adventure where you deploy heroes and try to fight off all kinds of enemies. As usual, the developers have decided to treat us players with some redeem codes to boost our start.
You will get lots of Gems (that you can use to summon more heroes), more than enough Summon Scrolls to pull a few heroes, and even an exclusive Legendary hero, Ignis, from the Idle Horizons codes. All of these will set you up for success if you happen to redeem them right at the beginning of your gameplay.
So, let's check them out.
Here are the working Idle Horizons codes

How to get more codes?
Sometimes, the devs can issue Idle Horizons codes on their social media accounts, like Discord. If you're not sure where to look, I recommend you save this page and take a peek every now and then, since we keep it updated!Codes not working?
You might have some issues redeeming some of the codes, especially with the "GCPOUTAGE0625" one. This code is only valid for some accounts.If you have issues with the other codes, make sure you type them exactly as shown (preferably copy and paste them), because they have a lot of zeros or the letter "o", and they are also case-sensitive.
That can make them pretty difficult to get right on your first go. So, it's best if you can just copy them from the list straight up.
About Idle Horizons
In Idle Horizons, the goal is to deploy a few powerful heroes and advance through the story stages. You will strengthen your heroes and slowly start seeking bigger and bigger challenges, like in the Arena. It's got a super fun PvP aspect, and you can even play it at your own pace.The gacha is quite rewarding, so you can easily power up your heroes by getting dupes. As someone who likes pixelated games and gachas, I think this is top-tier!
If you like a good RPG and you're looking for other freebies to grab, try Era of Warfare gift codes or Jujutsu Infinite codes in case you're more of an anime fan.
