How to Redeem Game Coupon Codes — Step by Step for Every Title
Genshin Impact, Honkai: Star Rail and Zenless Zone Zero all have a web redemption page, so codes can be entered without launching the game. Wuthering Waves is in-game only, and Cookie Run: Kingdom works only on the DevPlay web page. Below are the exact steps and pitfalls for each title. Arknights: Endfield, MapleStory: Idle RPG and AFK Journey are in-game only too, while CookieRun: Crumble and Tower of Adventures use DevPlay. For codes that work right now, grab them with one-click copy on the coupons page. Roblox game codes have their own page: Roblox codes.

18. Common pitfalls
Coupons expire without notice. Codes revealed during version preview livestreams are often valid for only a day or two, so redeeming the moment you see one pays off. Codes are case sensitive, so copy and paste beats typing them out, and each code works once per account. Variants of an expired code will not register, so lean on the coupons page, which keeps only verified, current codes — with one-click copy and [Redeem →] links that auto-fill the code.
19. Frequently asked questions
If you saw the success message, the reward is in your in-game mailbox. Delivery can lag slightly, so log back in and check the mailbox again.
Each coupon can be redeemed once per account. Either the same code was redeemed before, or the same account was used from more than one device.
Most official codes are shared across all servers. The reward goes to the character on the server picked at redemption, so make sure you select the server you actually play on.
The coupons page automatically collects verified codes only, and new codes also appear on the home page and in the RSS feed. Codes are released in bulk right after each version preview livestream.
