The Seven Deadly Sins

Review by eFreeware

The Seven Deadly Sins is a free role-playing game from Netmarble, built around the anime and manga of the same name. It has been running since March 2020 and has passed ten million installs on Google Play, with an average rating of 4.2 from a very large number of ratings. That combination of age and volume tells you something useful before you even start: this is an established game with a steady content pipeline, not a short-lived tie-in.

The pitch is straightforward. You follow the story of Britannia as the anime tells it, rendered in 3D, and you fight through it using a turn-based battle system built on skill cards. Alongside the main narrative there are game-exclusive storylines, so the game does not simply retell what you have already watched. For anyone who finished the anime and wanted more time in that world, that is the main draw.

Skill cards rather than a simple attack button

Combat is turn-based, but it is not just a matter of tapping attack and waiting. Each turn you are working with skill cards, and cards of the same rank can be lined up and combined into a stronger version. That single mechanic gives every turn a small decision: play what you have now, or hold and merge for a bigger payoff later. It is the sort of system that rewards planning a couple of turns ahead rather than reacting to whatever is on screen.

The developer describes the escalation as part of the appeal, with the stakes rising as a fight goes on, and the Ultimate Move as the finisher you build toward. I would expect the early story battles to be forgiving enough to teach the card system, and the difficulty to come from later content where the order of your skills matters more than raw numbers. That structure is common to the genre, but the merging rule gives it a bit more texture than a straightforward stat check.

What appeals to me here is that the strategy sits in the cards rather than in a long list of passive upgrades. You are still choosing what to bring into a fight, but the interesting choices happen during the battle itself.

Co-op raids and floors that keep climbing

Beyond the story, the game leans on group and challenge content. Death Matches are cleared together with friends in real time, which makes them the most social part of the package. Demonic Beast Battles are structured as floors, with each floor bringing a tougher version of the enemy, so progress there is measured in how deep you can push rather than in a single clear.

Demon King Battles are the other named challenge, and the developer frames them as a test of using the right skills at the right moment. That is the same card logic from the main game applied under more pressure, and it suggests these fights are where a well-built team and a good read of the turn order matter most. There is also an ongoing event structure, with the current update running an 85 million download festival that includes missions and an event boss battle against Bellmoth and the Original Demon.

The update also adds a new hero, the SSR God of Observation Heimdallr, and unlocks an LR evolution for Sun God Freyr, which gives long-term players something to work toward. A World Quest called Midnight Circus and a Fight Festival boosting event round out the current slate. The steady arrival of heroes, evolutions and events is the clearest sign that this is a game designed to be played over months rather than finished in a weekend.

Outfits, ads and in-app purchases

Costumes are a notable part of the offer. The game includes a large set of original outfits that exist only here, letting you dress the series' heroes in looks you will not see in the anime. For players who enjoy customizing a roster, that is a meaningful extra layer on top of the fighting, and it is the kind of feature that tends to keep people attached to a game long after the story is done.

On money, the facts are simple. The game is free to download, it contains ads, and it offers in-app purchases. The game does not lay out what any purchase includes, so I am not going to guess at what a given pack or pass gets you. Treat the ads and the store as part of the package and decide whether that is acceptable to you before you commit time to it.

The content rating is Teen, which is worth checking against the series if you are installing this for someone younger. The game is published by Netmarble, and the October 2026 update shows it is still being actively developed.

Who this is built for

This is a game for people who already know the Seven Deadly Sins story, or who are willing to meet it here for the first time. The 3D recreation of Britannia and the faithful retelling are the hook, and the extra storylines mean even a committed fan has something new to read. If you like the idea of a turn-based RPG where the card merging gives each turn a small puzzle, the combat will hold your attention past the tutorial stretch.

It also suits players who want a game with a social side. Death Matches are built around clearing content with friends in real time, and the floor-based Demonic Beast Battles give a group something concrete to chase together. If you prefer to play alone, the story and the challenge battles still stand on their own, but the co-op is clearly where the developer expects the long-term community to sit.

The main thing to weigh is the commitment. A game with this much ongoing content, a steady stream of new heroes and events, ads and in-app purchases is asking for a regular slot in your week. Players who dip in for a few hours and drift away will still get a story out of it, but the design clearly rewards the ones who stay.

A long-running anime RPG that earns its installs

The Seven Deadly Sins is a well-established free RPG with a distinctive card-based combat system, a faithful 3D retelling of the anime, co-op raids and a content schedule that shows no sign of slowing. The 4.2 average across more than 650,000 ratings is a fair reflection of a game that has kept a large audience engaged for years, and the current festival update shows Netmarble is still investing in it.

I would point fans of the series toward it first, and then anyone who enjoys turn-based battles with a bit of tactical layering rather than pure stat grinding. Be ready for ads and in-app purchases, and be ready to play regularly if you want to keep up with the events. For that audience, the install is easy to justify.
