Seven Deadly Sins Grand Cross Codes: Active and Expired (June 2026)
Last checked June 21, 2026 (UTC)
Netmarble drops Seven Deadly Sins Grand Cross codes around updates and events in this anime gacha RPG, and most of them hand you Diamonds and gold. I keep the working ones gathered here and we refresh the list whenever new ones land.
The Seven Deadly Sins: Grand Cross codes are the coupon codes Netmarble posts on the official Grand Cross social channels and during update events for free Diamonds, gold, and hero awakening materials. Grand Cross is a gacha RPG built on the anime, with a card-based combat system where you chain skills and ultimates. Diamonds pay for your summons to land new heroes, gold handles upgrades, and materials awaken your roster. The code rewards just get you to a PvP-ready or PvE-ready team faster.
Quick tip. save your code Diamonds for festival banners featuring a hero you'll actually build instead of pulling on every banner. PvP and the bosses reward a few well-geared meta heroes, so concentrating your summons lands a usable unit faster than spreading pulls thin.
Seven Deadly Sins Grand Cross codes show up during major updates, collaborations, and anniversary campaigns. They run on the usual gacha timeline, so each one expires after a window. You redeem on the Netmarble coupon page or in-game, and they're case sensitive.

The Seven Deadly Sins: Grand Cross codes FAQ
What do Seven Deadly Sins Grand Cross codes give you?
Mostly Diamonds, gold, and hero awakening materials. Diamonds bankroll your summons, gold handles upgrades, and materials awaken your roster. In short, the rewards get you to the team you need for PvP and the tougher PvE faster.
How should I spend the Diamonds from codes?
On festival banners featuring a hero you'll actually build. PvP and the bosses reward a few well-geared meta heroes, so concentrating your summons lands a usable unit faster than pulling on every banner. Save for the heroes you want.
Why does my code keep failing?
Usually one of three things: it expired, you already redeemed it on this account, or you mistyped it. They're case sensitive, so paste from the Copy button to keep the exact form.
Where do I redeem Grand Cross codes?
Two spots. On the official Netmarble coupon page in a browser with your player ID, or in-game through the coupon option. Either way the rewards land in your in-game mailbox, ready to claim.
Is Grand Cross friendly to free-to-play?
It's playable for free if you're patient. Codes, events, and login rewards keep a steady stream of Diamonds coming, so a free player can build a competitive team by saving for festival banners and leaning on a few meta heroes instead of pulling everywhere.
Where do I find the newest Grand Cross codes?
Follow the official Seven Deadly Sins Grand Cross channels and Netmarble's announcements. New ones drop during updates, collaborations, and anniversaries, and the official channels post them first, usually with the event notes.
