7DS Grand Cross Redeem Codes: Where to Find Them and How to Redeem
By Sir Ayup
7DS Grand Cross codes are coupon codes from Netmarble that unlock free items such as Diamonds, Anvils, SSR Evolution Pendants and Super Awakening Coins in The Seven Deadly Sins: Grand Cross. They can be redeemed inside the game or on Netmarble's coupon website, and most of them only work for a limited time. Knowing where they come from and why some fail saves a lot of frustration when a new batch appears.
This guide from gamemarket.gg explains where codes are released, how to redeem them in the game and on the web, what rewards they usually give, and how to fix the most common errors.
Where Codes Come From
Netmarble publishes codes through the game's official channels, mainly its X account (@7DS_en), Facebook page, Instagram and YouTube channel. New codes usually arrive with major updates, anniversaries, collaborations and livestreams, so checking around a big patch is far more productive than checking at random.
Codes are not released on a fixed schedule, and older codes tend to stay on fan lists long after they expire. A code copied from the official post is always the safest version to use.
How to Redeem 7DS Grand Cross Codes
There are two ways to redeem a code, and both deliver the same rewards.
Inside the game
- Finish the tutorial, since the menu is locked until then.
- Open the menu from the bottom-right corner of the main screen.
- Go to Misc. and open the Coupons tab.
- Enter the code exactly as written, tap Use and confirm.
On Netmarble's coupon website
- Copy your Netmarble ID (member code) from the game's account information.
- Open the official coupon page at coupon.netmarble.com/nanagb.
- Paste your Netmarble ID, choose the server your account plays on, and enter the code.
- Confirm, then check the game.
Codes have to be entered one at a time, and the web page asks for your Netmarble ID again for every code.
What the Rewards Look Like
Rewards are delivered to your in-game mailbox. If they do not appear right away, restarting the game usually refreshes it.
Code rewards change with every campaign, but they usually fall into a few groups:
- Diamonds, usually in small amounts such as 30 per code.
- Upgrade materials such as Anvils, SSR Evolution Pendants, SSR Enhancement Potions and Super Awakening Coins.
- Event boxes and tickets, including Legendary Seals, Skip Tickets and costume enhancement material boxes.
The Diamonds help most when they go toward a planned banner, and how Diamonds are earned and spent shows where codes fit next to daily and one-time sources.
Codes Reported in November 2026
In early November 2026, recent code lists from Pocket Tactics, BlueStacks and Destructoid all include these codes from the "777" anniversary batch:
- 777LEGENDRE: 1,000 Anvils
- 777NIGHTMARE: 77 SSR Evolution Pendants
- 777OURSPRING: Seventh Spring rewards
- 777PERFECT: Super Awakening Coins
- 777FLAME: costume enhancement material boxes
No official expiry dates have been published, and the lists disagree on some older codes, so treat any code as possibly expired until it works in your game.
Why a Code Fails
When a code is rejected, the cause is usually one of these:
- The code has expired. Most codes are tied to an event and stop working when it ends.
- The code was mistyped. Spelling and capitalization can matter, and a space before or after the code can break it.
- It was already used. Each code normally works once per account.
- The wrong server was selected. On the web page, the server has to match the account, and some codes are only available on certain servers. How the 7DS servers are split explains why the same code can behave differently.
- It belongs to another game. Codes for The Seven Deadly Sins: Origin use a separate system and do not work in Grand Cross.
If the code is correct and still fails on the web, redeeming it from the in-game Coupons tab rules out a wrong Netmarble ID or server.
Keep Your Account Safe While Redeeming
A real code never needs your password. Sites that promise "Diamond generators" or ask you to log in with your Netmarble, Google or Facebook credentials are trying to take over the account, not reward it. Keeping a backup login also protects your progress, and how account linking works in 7DS covers which options to set up. If a code ever runs on the web but the game will not accept your login, login methods and common errors walks through the fixes.
Small Codes, Steady Progress
Codes will never carry an account on their own, but the materials they give add up over a year of campaigns. Newer players will get more out of them after reading the 7DS Grand Cross beginner's guide, and when free Diamonds are not enough for a banner, 7DS Grand Cross Top Up on GameMarket holds your payment until the Diamonds arrive.
If you would rather start with a strong roster already built, you can browse 7DS Grand Cross Accounts, hand daily missions and events to a verified player through 7DS Grand Cross Hourly Services, or push PvP and boss content faster with 7DS Grand Cross Boosting.
