How to redeem a coupon
Netmarble’s notice links to its official coupon redemption guide and coupon page. The notice text does not provide the full interface instructions, so use the guide for the current redemption steps rather than relying on guessed menu names.
- Each code may be redeemed once per account.
- Verify your character name before submitting a code.
- Redeemed rewards are sent to your in-game mailbox.
If a reward does not appear
Netmarble advises restarting the game if a coupon reward is missing. The notice also says the publisher cannot restore a coupon after redemption or help recover rewards missed because the coupon period or mailbox storage period expired. Check your mailbox promptly after claiming.

Check code dates before using older lists
A page labeled for October 2026 may still display codes whose validity has already ended. For example, a BlueStacks code-list page shows TIMEWARP, CATCHCATCH, and GEMSTONE with an April 30, 2026 validity date, which had passed by October 5. Its STONELAUNCH entry is not corroborated by Netmarble’s Half-Year Celebration notice. For the five codes above, rely on the publisher’s stated rewards and expiration dates.
