In The Seven Deadly Sins: Grand Cross, codes work a bit differently.
To claim a code, you need to have the secret box it’s for, which you get from the notice tab in your mailbox.
Therefore, if you started playing after a secret box was sent out, you cannot use its code for anything.
To ensure active codes work, type them in, in the exact same capitalization as shown in the list above.
By leveraging the rewards of these codes, you can speed up your progress.
If you get an error message when trying to redeem a code, it means that you’ve either typed it in incorrectly, that you aren’t eligible to receive it, or that it has expired.
If you notice that any active codes listed above have expired, please let us know in the comments.

We always appreciate it when readers share new active codes they find with us or if they let us know that an active code has expired.
How to redeem secret box codes in 7DS Grand Cross
To redeem codes in 7DS Grand Cross, you, first of all, need the secret box the code is issued for.
You can get secret boxes from the notice tab in your in-game mailbox when the developers sent them out.
If you don’t have a secret box a code is issued for, you cannot use that code is for.
Once you have a secret box, go to Menu at the bottom of the screen.
Select Item Storage, which is unlocked after completing chapter 1.
Go to 1-Use and find the secret box.
Type in its code in the Enter Code field and click Open.
You will then receive the rewards of the box.

What are secret box codes
Secret box codes are codes issued by the developers of The Seven Deadly Sins: Grand Cross for players to use to open secret boxes.
When you redeem a secret box code, you receive the rewards of the code.
Usually, box codes and secret boxes are issued when new major updates are released, holidays come around, special promotions start, or other celebrations.
After a while, codes expire, so be sure to redeem them before it’s too late.
As codes can be announced on many different platforms, including the game’s own social media, it can be difficult to find them all in time.
To make it easy for you, we’ve created this codes list that gives you all active 7DS Grand Cross codes in one place.
Players of the game can take advantage of these codes to progress faster, so check back from time to time to see if new codes have been released.
How to get more codes and boxes
There is only one way to get more codes and boxes in the game, and that is to wait for the developers to issue new ones.
As codes and the release of new boxes can be announced both on social media, in advertising, directly through content creators, or through other means, we’ve made this list to make it easier for you to find codes.
We will add any new active promo code we find to this list, so you can keep up with new codes by simply checking out this post once in a while.
