About the game
Build your own crime syndicate
Mafia Inc. is a free mafia browser game in which you build your own criminal syndicate, take control of businesses and entire city districts, and fight thousands of other players for supremacy in the underworld. As a turn-based strategy and economy game, Mafia Inc. combines building a criminal empire with hard-hitting PvP, diplomacy and betrayal — right in your browser, with no download or installation. If you are looking for a gangster browser game with real depth, you have found the original, played since 2003.
What is Mafia Inc.?
Mafia Inc. is a browser-based mafia MMO set in the golden gangster era. You start with nothing and work your way up from small-time crook to feared boss: you construct buildings, grow your economy, recruit units and take control of the city district by district. Each game world runs as its own round with a clear beginning and end — whoever holds the most powerful syndicate and the greatest influence at the finish writes mafia history.
Unlike many browser games, the focus here is not on clicking but on strategy, timing and reading people. Mafia Inc. is a building game, an economic simulation and a PvP strategy game all in one — a real mafia strategy game you can play for free in your browser anytime.
History since 2003
Mafia Inc. is one of the oldest mafia browser games and has been played since 2003. Over more than two decades, countless game worlds have come and gone — from Las Vegas to Leticia, players have fought for territory, power and respect since 2010. Generations of bosses and syndicates have built their empires in these rounds and watched them fall again.
This long history has grown a tight-knit community. That heritage is exactly what makes Mafia Inc. more than just another online game: it is the original that other mafia browser games are measured against.
Game mechanics: building, structures & units
At the heart of Mafia Inc. is building your criminal empire. On the territory map you take over districts, secure smuggling routes and keep an overview of your growing realm. In the building view you choose structures with different bonuses and raise your empire stone by stone — from the first backyard workshop to a fully organised crime operation.
Your units and troops decide attack and defence. You recruit men, equip them and position them strategically, because every decision counts in the next fight. Anyone who neglects their defence can lose everything overnight.
Syndicates & social play
No one survives the underworld alone for long. That is why you join other players to form a syndicate — the most powerful social unit in the game. Within a syndicate you manage members, assign roles and coordinate joint attacks on enemy territory.
Diplomacy, alliances and betrayal are as much a part of the game as open war. Trust is a currency — and a particularly dangerous one in the underworld. The best syndicates win their rounds not only through strength, but through clever agreements and a feel for the right moment.
Economy system & trade
Power in Mafia Inc. is built on money. Your buildings and businesses generate income that you reinvest into expansion, troops and influence. On the black market you trade resources at fluctuating rates — whoever secures the best prices gains a decisive edge.
The economy rewards forward planning: when do you invest in defence, when in expansion, when do you hold your capital together? This constant balancing act makes Mafia Inc. a true economy browser game where brains beat brute force.
PvP, wars & events
Mafia Inc. is a PvP game at its core: you fight real players for territory, loot and leaderboard positions. Real-time rankings show who currently rules the underworld — the top bosses and top syndicates of every round compete in the open. Wars between syndicates decide the rise and fall of entire empires.
Between the battles, regular events and special game worlds keep things fresh. Every round has its own character, its own alliances and its own legends — and in the end always only one player standing at the very top.
Version 3 – the underworld reborn
More than twenty years after the original, Mafia Inc. returns with Version 3 — a completely rebuilt engine, modern design and new features. These include new cities and territories from New York to Palermo, an expanded espionage system with agents and double agents, dynamic real-time wars, and a deeper economy with black markets, smuggling routes and money laundering.
A new character system lets you develop your boss across rounds with unique traits, reputation and history. And thanks to a mobile-first design, you will be able to play Mafia Inc. just as well on smartphone and tablet as on desktop. Sign up to the newsletter to be among the first when Version 3 launches.
