The Seven Deadly Sins: Grand Cross APK

The description of The Seven Deadly Sins: Grand Cross APK

The Seven Deadly Sins: Grand Cross APK is Netmarble's official global anime gacha RPG, the same client that runs on the worldwide servers, packaged here as a clean install file for Android. This is the real game, not a mod: the download button on this page gives you the original global build, scanned for malware and installed on a real Android device by our editors before publishing, as we have done since 2018. One thing to know up front, it is an online game, so you need an internet connection to play, not only to install.

What is The Seven Deadly Sins: Grand Cross?

The Seven Deadly Sins: Grand Cross is a role-playing game by Netmarble, based on Nakaba Suzuki's manga and anime about the knights of Britannia. Combat is 3D and turn-based, built around a card system: each turn you draw skill cards and combine matching cards to rank them up, and stacking the right cards sets off a character's Ultimate Move. Voice actors from the anime dub the cast, so scenes play close to the show.

Netmarble launched the game in 2019 and the global service in 2020, and it reached its seventh anniversary in 2026, so the servers are active, not shut down. The package name is com.netmarble.nanagb, which is how you tell the official client apart from a repackaged one.

Gameplay and modes

You build a team by collecting heroes through the game's gacha summons. The roster is drawn straight from the series: Meliodas, Ban, King, Diane and many more, each with their own skills and card set. Characters grow through awakening and limit-break, which raise their rarity and stats.

Outside the story campaign there is plenty to do:

• PvP Arena, where you fight other players' teams.
• Death Match and boss battles for tougher, timed fights.
• Clan and co-op content you take on with other players.
• Town building at the Boar Hat, your home base between battles.

Two things live on Netmarble's servers, not on your phone: your account progress and the gacha currency you spend on summons. That detail matters for the section below.

Is it online? Internet and account

The Seven Deadly Sins: Grand Cross is an online game from start to finish. You sign in with a Netmarble account or a linked social login, and your team, your progress and your currency all sit on the server. That means you need a steady internet connection the whole time you play, not just for the first install.

If you have read elsewhere that the game needs the internet only to download, that is wrong. Close the connection and the game stops. Keeping your login details safe matters too, since the account, not the phone, holds everything you have built.

The "mod APK" myth and ban risk

Search for a 7DS Grand Cross mod and you will find pages promising unlimited gems, god mode or every character added at once. For a server-authoritative gacha, that cannot work. Your gems, your pulls and your roster are values Netmarble stores and checks on its own servers, so a file on your phone cannot write new currency into your account. If a mod could hand out free premium currency, the game's economy would fall apart in days.

What those third-party builds actually carry is client-side tampering: a speed multiplier or a mod menu injected through tools like LSPosed. In an online game the server sees the abnormal result, and that is where accounts get flagged. Netmarble's terms of service forbid this, and the outcome is a banned account, not free gems. The button here gives you the plain original client, with nothing injected, so there is nothing to get you banned.

How to download and install The Seven Deadly Sins: Grand Cross APK

The file on this page is the original global client, about 164 MB, for Android 7.0 and newer. The install is quick:

1. Tap the green Download APK button at the top of this page. The file downloads directly, no registration or SMS.
2. Allow installation from unknown sources for your browser or file manager (Settings, then Security).
3. Because this file is the original client, its signature matches the Play Store build, so you can install it over an existing copy without removing it first.
4. Open the file, tap Install, launch the game and sign in to your Netmarble or social account. The game pulls extra data on first run, so stay on Wi-Fi.

Original vs third-party mods

The Seven Deadly Sins: Grand Cross is free to play. Summons and cosmetics are optional purchases, and you can compete without spending, so there is no paywall to get around. The safest copies come from the official Play Store or from a verified file like the one here.

Mod aggregators tend to post older or repackaged builds that fall out of date the moment the game updates, and any speed multiplier or mod menu inside them puts your account at risk. The original costs nothing and keeps your progress safe, which makes the choice simple. Want more like this?
