The Seven Deadly Sins: Grand Cross codes (November 2026)

This page is part of our game codes hub. Codes here are for The Seven Deadly Sins: Grand Cross, the anime card battle RPG by Netmarble on Android, iOS and the PC beta. They do not work in The Seven Deadly Sins: Origin or IDLE; each Netmarble game has its own coupon system. If you also play Solo Leveling: Arise, you already know the routine: the same Netmarble coupon site, the same Member code, only a different game page.

Working 7DS Grand Cross codes

Netmarble announces Grand Cross coupons in [Event] posts on the official forum, each with the code, the reward banner and a deadline to the minute. The table below is built from those posts only: the Persona 5 Royal collab coupon of October 28, 2026, the 6.5th Anniversary coupon, the New Year Festival 2026 coupon and the "777 Relay Grand Finale" overview of June 25, 2026, which lists every 777 code with its end date. Netmarble gives times in PST or PDT; we converted them to UTC. Every deadline lands on 06:59 PST or 07:59 PDT, which is 14:59 UTC either way.

Two codes run out on November 19, 2026: TAKEYOURSINS, the collab coupon worth 10 Pick Up Tickets for the 7DS x Persona 5 Royal banner, and LIGHTNDARK for 30 Diamonds, which has been live since the 6.5th Anniversary Apocalypse Festival a year ago. The 777 codes come from the 777 Relay campaign that ran from December 2025 to June 2026 and last until May 2027, but there is no reason to wait. Each code works once per account.

777OURSPRING pays a selection box that the official 777 Relay site calls "Our Seventh Spring Box"; Pocket Tactics (updated November 8, 2026) names the same box. Trackers do not agree on what is inside it, so we do not list the contents: open it in game and pick. 777PERFECT pays the True Awakening material Supreme Deity's Protection; the banner shows a bundle of items, and Netmarble's text does not give a count, so we do not either.

How to redeem on the Netmarble coupon page (iOS, PC and Android)

iPhone and iPad have no redeem box inside the game, so the web page is the only route on iOS. It also works for Android and PC accounts, and it is the quicker way when you have a list of codes. The official 7DS Coupon Page asks for three things: your Member code, your server and the coupon code.

1. Copy your Member code. In the game go to Menu, Player Info, then the Player info tab, and copy the Netmarble ID. The coupon page calls it Member code; it is the same number.
2. Open coupon.netmarble.com/nanagb in any browser. The page is titled "7DS Official Coupon Page". Type the address yourself or use the Coupon Register Page link in the official forum menu.
3. Paste the Member code into the first box and confirm it. The page then loads the servers for that account; pick the one you play on.
4. Enter the coupon code and press Use. A dialog says which server the item goes to; confirm it.
5. Restart the game. Netmarble's posts say you must reconnect once (the PC beta included) before the reward appears, and then it lands in your in-game mailbox.

Two warnings straight from the coupon page: if you enter the wrong server or Member code, "the rewards may not be recoverable", and ten invalid codes in a row lock you out for an hour. Paste the official codes first and only then experiment with older lists. The page has to be filled in again for every code.

Both banners above are the original reveal posts: LIGHTNDARK from November 2025 with its end date printed on the ticket, and 777INFINITE from the New Year Festival 2026, which also handed out 100 Diamonds for logging in.

How to redeem in game on Android and PC

Netmarble's own "How to Use Coupon Codes" guide lists the in-game route for Android devices only:

1. Open the Menu button in the bottom right of the Tavern screen.
2. Tap Misc. in the menu grid.
3. Tap Coupons and pick the Escanor entry in the coupon list.
4. Enter the code and confirm, then restart the game if the reward is not in your mailbox.

PC: the Windows version runs as a beta through Netmarble's own PC launcher; Grand Cross is not on Steam. The coupon page notes that you can redeem for the PC version too, then restart the PC client. iOS: use the web page. Your progress, and your Member code, are tied to the Netmarble account, not the device, so a code redeemed once is gone on every platform.

Why a 7DS Grand Cross code does not work

The messages below are the ones the official coupon page shows.

The region error is worth knowing: Netmarble's Discord coupon notice from May 2026 says codes from the event channel only work in the region your account plays in, and Korean server players cannot use them on the Japanese or Global servers. Stick to codes from the English forum and its official channels.

Where Netmarble posts new Grand Cross codes

• The official forum, [EN] News board (forum.netmarble.com/7ds_en). Every coupon of the last year was announced there in an [Event] post with the exact deadline. This is the source to bookmark.
• Big events and collabs. The pattern is clear from the forum: a coupon for each anniversary festival (6.5th Anniversary, 7th Anniversary), one for the New Year Festival and one for a major collab such as Persona 5 Royal.
• Discord hidden coupons. The official Discord (discord.gg/7dsgc) runs first come, first served drops. The 7th Anniversary drop on May 20, 2026 gave 10 Diamonds to the first 5,000 players.
• X, Facebook and Instagram. The official accounts @7DS_en, facebook.com/7ds.en and instagram.com/7ds.en repeat the coupon banners.
• Boar Hat livestreams. Netmarble streams its official 7DS broadcasts on YouTube before big festivals, for example on August 19, 2026 for the Apocalypse Festival special, with a special event during the show.

What the code rewards are worth

For a fresh account, the most valuable picks are the ten collab tickets, the 30 Diamonds and the selection box from 777OURSPRING. The rest are materials you will need later anyway, so claim them now and let them sit in the inventory.

The official App Store listing (version 2.116.0, updated November 12, 2026) shows where those materials go: the original anime story, the newer Four Knights of the Apocalypse chapters with Percival, and a long list of heroes to awaken and evolve.

Beyond codes: the Persona 5 Royal collab

The collab is where the real free pulls are in November 2026. According to Netmarble's October 28 maintenance notice and the collab banners:

• Four collab heroes: [The Phantoms] Joker, Queen and Violet on the Pick Up Draw, and Mona, whom you get just by playing.
• Pick Up Draw and Guaranteed SSR Draw run until November 19, 2026, 10:59 PM PST. Reach 600 Loyalty Points to choose one collab hero.
• Check-in events pay up to 70 Diamonds and 30 Tickets, and the special missions, the Spin Event and the Kamoshida event boss all end at the November 18 maintenance.
• The title "TAKE YouR hEaRT" for clearing all collab title missions can only be earned until the November 18 maintenance.

The November 11 update brought a new hero draw for [The Prince's Master] Highest-ranking Demon Cusack and Season 12 of the Liones Defensive War, which runs until the November 25 maintenance. Grab the collab rewards first: they disappear a week earlier.

Expired codes and why code lists disagree

Third party lists for Grand Cross are unusually messy in November 2026. Pocket Gamer (updated November 7, 2026) still lists 7DSGCx7DSI, PDKOO2025GIFT and BOARHATSEASON3 as working, while Netmarble's own posts ended 7DSGCx7DSI on December 31, 2025 and PDKOO2025GIFT on December 25, 2025. Pocket Tactics (updated November 8, 2026) lists 777INFINITE as active and expired at the same time; the official deadline is December 25, 2026, so it still works. When a tracker and the forum disagree, the forum wins.
