Outerplane Codes: Active and Expired (June 2026)
Last checked June 21, 2026 (UTC)
Smilegate drops Outerplane codes around updates and anniversaries, and I keep the working ones tracked here so you don't waste time on dead ones.
Outerplane codes are the alphanumeric strings Smilegate posts on the official Outerplane channels and through the STOVE community for free Star Diamonds (the premium currency), Selena's Coins, Stamina, Gold, and Hero upgrade materials. Star Diamonds are what you spend on the summons that recruit new Heroes in this anime turn based RPG. Selena's Coins buy from the exchange shop, Stamina gates your farming, and the upgrade materials push your roster past the soft cap.
Quick tip. bank your Star Diamonds from codes for the rate up Hero banners instead of the standard pool. Outerplane rewards a tight team of well built Heroes for the Challenge and PvP content, and the limited rate up Heroes are the ones that shift the meta, while standard pulls just thin out across the whole roster.
Outerplane codes show up during major updates, anniversary events, and Smilegate milestone campaigns, and they run on a normal gacha timeline. You redeem on the STOVE coupon page or in game through the settings menu, and the codes are case sensitive.

How to redeem Outerplane codes
Outerplane gives you two ways in. The STOVE coupon page works from any browser, and the in game settings menu has a coupon option too. Either way, rewards land in your in game mailbox.
On the STOVE coupon page
- Open the official Outerplane STOVE coupon page in any browser.
- Sign in with the STOVE account linked to your Outerplane save.
- Enter the coupon code, then pick your server and nickname.
- Hit Submit, and the rewards drop into your in game mailbox.
- Launch Outerplane and claim them from the mailbox.
In game (settings > coupon)
- Open Outerplane and tap the settings menu.
- Find the coupon or redemption code option.
- Enter the code exactly as shown, since it's case sensitive.
- Confirm to redeem, and the rewards land in your in game mailbox.
If the STOVE page can't find your nickname, double check you picked the right server first. Outerplane nicknames are server specific, same as the other STOVE published games.
Outerplane codes FAQ
What are Star Diamonds used for?
Star Diamonds are the premium currency for the summons that recruit new Heroes in Outerplane. They're the resource gating your roster growth, so any code drop that includes Star Diamonds is the one collection focused players should care about most.
Should I save for rate up Hero banners?
Yeah, I would. Outerplane rewards a focused team of well built Heroes for Challenge and PvP, and the limited rate up Heroes are what move the meta, while standard pulls just dilute across the full roster. Bank your code Star Diamonds for those rate up banners.
Where do I redeem, STOVE or in game?
Either works fine. The STOVE coupon page is handy when you want to redeem across devices, and the in game settings menu is quicker if you're already playing. Both deliver to the same mailbox, though STOVE makes you pick your server and nickname first.
Why does my code keep failing?
Usually one of three reasons: it expired, you already used it on this account, or you slipped on the capitalization. Outerplane codes are case sensitive, so lean on the Copy button to keep the exact form.
Do codes work on the PC client?
They do. The Outerplane PC client shares your STOVE account with mobile, so redeem on either one and the rewards drop into the same in game mailbox.
How long do mailbox rewards stay claimable?
Thirty days for most code rewards. Open your in game mailbox and clear everything before the timer runs out, especially the Star Diamonds you'll want for the current banner.
