All five published expiration times are still ahead as of October 5, 2026, at 01:14 UTC; redeem them promptly because the notice does not guarantee that every code will work for every account.

- The TJX gift card is redeemable at all HomeGoods, TJ Maxx, Marshalls, Sierra, and Homesense stores (in the U.S. and Puerto Rico) and online at TJ Maxx, Marshalls, and Sierra.
- Physical gift cards are delivered active via mail.
- Open Netmarble’s official coupon redemption guide and follow its current instructions to reach the coupon page.
- Before submitting a code, verify that the character name shown is the character you want to receive the reward.
- Enter one of the codes exactly as listed above and submit it. Each code is limited to one redemption per account.
- Check the character’s in-game mailbox for the reward.
If a reward does not appear, Netmarble advises restarting the game. The publisher says it cannot restore a coupon after redemption or assist with rewards missed because a coupon expired or the mailbox storage period ended.
Check code dates before using older lists
Some third-party pages may retain old codes under a newer-looking page date. For example, a BlueStacks October 2026 page lists TIMEWARP, CATCHCATCH, and GEMSTONE with an April 30, 2026 validity date, which had passed by October 5. Its STONELAUNCH entry is not confirmed by Netmarble’s Half-Year Celebration notice. For these October codes, use the publisher’s notice and its stated deadlines rather than assuming a code on an older list remains active.
