Eternal Evolution Codes: Active and Expired (June 2026)
Last checked June 21, 2026 (UTC)
Eternal Evolution codes drop around updates and events, and I keep the working ones listed right here so you can grab them before they lapse.
Eternal Evolution codes are alphanumeric strings Star Heart Studio releases on the official Eternal Evolution Facebook, Discord, and event announcements for free Diamonds (premium currency), Recruit Tickets, Gold, Hero EXP, and gear upgrade materials. Diamonds are the premium currency for the gacha that recruits new Heroes in this sci fi idle RPG. Recruit Tickets pull directly. Gold and Hero EXP feed the idle progression that levels your roster while you're off doing something else.
Quick tip. My tip: save the Diamonds and Recruit Tickets from codes for the rate up Hero banners rather than the standard pool. Because the game is idle, base resources pile up on their own over time, so your gacha currency is best spent the moment a meta Hero gets boosted summon odds.
Codes turn up during major updates, anniversary events, and Star Heart Studio milestone campaigns. They run on a normal idle gacha timeline, so don't sit on them too long. You redeem in game through the settings menu, and the codes are case sensitive. Your account also has to be past the early prologue.
- You redeem in game through the settings menu.
- Most codes expire within 14 to 30 days of release.
- Each code is single use per account.
- Codes are case sensitive. Use the Copy button to dodge typos.
- Diamonds and Recruit Tickets are the code rewards worth chasing for roster building.

How to redeem Eternal Evolution codes
Eternal Evolution handles redemption in client through the settings menu. There's no web portal, and the rewards land in your in game mailbox.
- Open Eternal Evolution and tap your profile or the settings icon.
- Find the redemption or gift code option.
- Type or paste the code exactly as shown (it's case sensitive).
- Confirm to redeem.
- Open your in game mailbox to claim the Diamonds, Tickets, and materials.
If the redemption option is nowhere to be found, you probably haven't finished the early prologue yet. The code field unlocks once you clear the tutorial section of the campaign.
Eternal Evolution codes FAQ
What are Diamonds used for?
Diamonds are the premium currency for the gacha that recruits new Heroes in Eternal Evolution. They're the resource gating your roster expansion, so code drops with Diamonds in them are the most valuable for collection focused players.
Should I save for rate up banners?
Yes. Because the game is idle, base resources accumulate on their own while you're away. The gacha currency (Diamonds and Recruit Tickets) is the real bottleneck, so spend it when a meta Hero gets boosted odds on a rate up banner.
Why does my code keep failing?
Three usual suspects. It expired, you already used it on this account, or you've got a capitalization slip. Eternal Evolution codes are case sensitive, so use the Copy button to keep the exact form.
Is Eternal Evolution pay to win?
Like most idle gachas, spending speeds things up, but the idle structure is pretty generous with free resources. Codes, daily idle rewards, and events hand out enough Diamonds for a free to play account to build a competitive team over time, especially if you funnel your summons into rate up banners.
How long do mailbox rewards stay claimable?
Fourteen days for most code rewards. Open your in game mailbox and claim everything before the timer runs out, especially the Diamonds you'll want for the current banner.
Where do I find the newest Eternal Evolution codes?
Follow the official Eternal Evolution Facebook page and Discord. Codes drop during updates, anniversary events, and milestone campaigns, and the official channels post them first, usually with the update notes.
