Redemption Guide
5 platformsUse the official Netmarble coupon page with the Member Code and server belonging to the account that should receive the reward. Android also supports an in-game coupon route after the opening tutorial.
Code Rules & Troubleshooting
The most common failure is an expired coupon, an already-used coupon, or an incorrect Member Code and server combination. Each coupon can be claimed once per account, so a second redemption on the same account will not provide another reward.
After a successful redemption, log back into the game and check Mail. If an active coupon still fails, copy its capitalization exactly and confirm that you are using the Grand Cross coupon page rather than a code system for another Seven Deadly Sins game.
New Code Announcements
New Grand Cross coupons are released through official anniversary campaigns, update announcements, the official forum, X account, YouTube programs, Discord promotions, and special event pages. The seven-part 777 Relay Campaign supplied the current long-running coupon set, with 777ENDAND released as its final phase.
Trailer, Screenshots & Media
The selected media covers the current global 6.5th anniversary, the seventh anniversary Perfect 7 festival, the 777 Relay Campaign updates, Gachiakuta, Fire Force, Dreamy Night, Seventh Spring, and earlier anniversary content.

Coupon rewards are delivered through the in-game Mail. Log back into the game after redeeming a coupon and open Mail to collect the items.
The in-game coupon menu is not available until you finish the opening tutorial and reach the main lobby. Complete the tutorial, then open Menu, Misc, and Coupons.

Yes. The official coupon page works for PC accounts as well. Redeem the coupon with the Member Code and correct server, then log back into the PC version to receive the reward.
