You know what’s funny? I started playing The Seven Deadly Sins: Grand Cross just because I liked the anime. I figured it’d be another quick mobile RPG I’d ditch in a week. Instead, here I am in 2026, still grinding dailies and hunting for new redeem codes like it’s a full-time job. And honestly? If you’re not keeping up with the latest codes, especially in the US version, you’re leaving a lot of free stuff on the table.

What Are The Seven Deadly Sins Mobile Game Codes?

So let’s break this down in real human terms.

Redeem codes in 7DS: Grand Cross are kind of like backstage passes. They’re short character strings that unlock free in-game items — sometimes it’s stamina pots, sometimes diamonds, sometimes you get lucky and pull an SSR character ticket out of nowhere. And no, it’s not cheating. Netmarble wants you to use these. They drop them as part of promotions, collabs, anniversaries, or just to keep us logging in.

Think of it this way: you know how gacha games are built around luck? Redeem codes are the rare moment when everyone wins something, no RNG involved.

I’ve seen codes give out:

• 5–30 diamonds (basically premium currency)
• Stamina potions, which are like gold if you’re farming during events
• Evolution pendants, because there are never enough of those
• Full-on SSR hero tickets — though those are rare and usually tied to big events

You just copy the code, plug it into the game’s redemption portal, and boom — gifts land right in your in-game mail. It takes under a minute once you know where to go (more on that below).

Active Seven Deadly Sins Game Codes (Updated for 2026)

Here’s what’s working as of January 2026 on the US server. I tested these myself on both Android and iOS (yep, I’m that person with a phone in each pocket).

These change fast, so here’s what I do: I check the official 7DS Discord and Twitter weekly. Netmarble loves dropping codes quietly during livestreams or patch notes, especially for US players around holidays.

Tip: Bookmark this guide. I update my code list every month, usually right after Netmarble pushes their global patch notes. If I can’t redeem a code myself, I don’t list it — no fakes.

How to Redeem Codes on iOS and Android

You’d think this would be more obvious, but honestly, I’ve lost count of how many people DM me saying “where do I enter the code?” — and hey, I was one of them at first.

Here’s how it works (US version, both platforms):

For Android:

1. Open 7DS: Grand Cross.
2. Tap the menu icon (top-right).
3. Go to Settings > Misc.
4. Tap Enter Coupon Code.
5. Paste the code and hit Confirm.

For iOS:

Netmarble doesn’t allow code entry in-game on iPhones (blame Apple’s App Store rules), but there’s a workaround:

1. Go to Netmarble’s code redemption site
2. Select 7DS: Grand Cross.
3. Enter your Player ID (found in your player profile).
4. Enter the code.
5. Rewards show up in your in-game mailbox within a few minutes.

Troubleshooting tip: If a code says “invalid,” double-check for typos or spacing. And make sure the code hasn’t expired — some last 24 hours, others run all month.

Best Rewards You Can Get from Redeem Codes

Okay, so not all codes are created equal. Over the last year or so, I’ve tracked more than 80 codes, and here’s what I’ve found in terms of value:

Personally, I get most excited when they drop SSR tickets tied to seasonal events. That’s how I landed my Halloween Gowther last year — no diamonds spent. If you’re F2P or low-spend, code rewards can carry you through dry patches between banners.

US Holidays & Events That Drop Exclusive Codes

Now, this is something I didn’t pay attention to until late 2024 — and I regret it. Netmarble loves tailoring their code drops to US holidays.

Here’s a rough annual schedule based on past years:

• July 4th: Patriotic-themed banners and codes
• Halloween: Costume event + scary-good code bundles
• Thanksgiving: Usually stamina-heavy codes for marathon events
• Christmas/New Year: Best time for diamonds + SSR ticket drops
• Valentine’s Day: Romantic banners with small freebie codes

I tend to check around 2–3 days before and after each holiday — sometimes the codes drop early via content creators.

Where to Find New Codes First (US-Optimized Sources)

Here’s where I actually find the codes before they hit mainstream lists.

1. Netmarble Twitter (@7DS_en): They sneak codes into announcement tweets and livestream recaps.
2. 7DS Official Discord: The mods are quick to pin new code drops in the #announcements channel.
3. Reddit (r/SevenDeadlySinsGrandX): It’s messy, but when a code drops, someone always posts it.
4. YouTube Creators: Look for guys like Nagato, Shiny, or Speedy — they often leak codes during patch previews or update guides.

What I do is keep a Google Doc with pinned links to those sources and check them every Monday and Friday — it’s become a bit of a routine at this point.

Final Thoughts

Honestly, redeem codes have become one of my favorite parts of 7DS: Grand Cross. Not because they’re flashy, but because they’re that little boost when you need it most. Missed a banner? There’s a code to soften the blow. Burning out during a grindfest? Stamina code to the rescue.

They won’t carry you through PvP or suddenly make you god-tier, but they do help stretch your resources, especially on the US server where some event pacing differs from Korea or JP.

And hey, if you’ve read this far, do yourself a favor — copy the active codes above, redeem them now, and check back here next month. I’ll keep testing and listing the new drops. We might not beat the whales, but we can at least stay fed.

See you in the next banner.
