What Is the Mafia Game?

Mafia is a social deduction party game where players are secretly divided into two teams: innocent Citizens and a hidden Mafia. The Citizens try to figure out who the Mafia members are and vote them out. The Mafia tries to eliminate Citizens one by one without getting caught. It's a game of lying, reading people, and trusting your gut.

• 6–16 players sit in a circle. One person is the Game Master (GM).
• Everyone is secretly assigned a role: most are Citizens, a few are Mafia.
• The game alternates between Night (eyes closed, Mafia secretly picks someone to eliminate) and Day (everyone debates and votes to eliminate a suspect).
• Citizens win if they vote out all Mafia. Mafia wins if they equal or outnumber the Citizens.

That's it. Everything else — special roles, house rules, variants — builds on this core. For the full rules, see our complete rules guide.

Mafia was invented in 1986 by Dimitry Davidoff, a psychology student at Moscow State University. He designed it as a thought experiment about informed minorities versus uninformed majorities.

The original game had no special roles — just Citizens and Mafia. Over time, players added roles like the Sheriff (who can investigate players), the Doctor (who can save someone), and dozens more.

From Moscow, the game spread to European universities in the 1990s, then to American college campuses. In the West, it was re-themed as "Werewolf" (villagers vs werewolves instead of citizens vs mafia), but the gameplay is identical.

Today it's played worldwide — in Russian mafia clubs, at American house parties, on Korean variety shows, and in Iranian cafes where it's a cultural phenomenon.

No equipment needed. You can play with nothing but people. No board, no cards, no screen.

It's about reading people. Unlike most party games, Mafia is fundamentally about human psychology. Can you tell when your friend is lying? Can you lie convincingly to a room full of people staring at you?

Everyone is involved. There's no waiting for your turn. Day phase is a free-for-all debate where everyone talks, accuses, defends, and bluffs.

It scales. Works with 6 people at a dinner table or 16 people at a party. The dynamics change with group size, but the game works.

It's different every time. The same group of friends will produce wildly different games depending on role assignments, alliances, and who happens to make a suspicious face at the wrong moment.

Mafia has no board, no dice, no resource management. It's closer to an improv exercise than a traditional game. The core mechanic is conversation — persuading other people that you're telling the truth (or that someone else isn't).

This makes it polarizing. People who love debate and social reading adore it. People who prefer clear rules and strategy over social maneuvering sometimes find it frustrating.

One person doesn't play — they run the game. The Game Master:

• Assigns roles at the start
• Narrates the night phase ("The city falls asleep...")
• Wakes each role in turn and records their choices
• Resolves night actions (kills, heals, blocks)
• Announces results in the morning
• Manages day discussion and voting

Being GM is a skill. A good GM keeps the pace fast, narrates with flair, and tracks everything without mistakes. Need a ready-made script? See our complete GM hosting guide. A game master tool helps by handling role assignment, action tracking, and resolution automatically.

Classic Mafia

The original: Citizens vs Mafia, plus Sheriff and Doctor. Played widely in Russia and post-Soviet countries with a strong competitive tournament scene.

Werewolf (The Werewolves of Miller's Hollow)

The European/American re-theme. Same game, different flavor. Villagers vs Werewolves, with roles like the Seer (Sheriff), Witch, Hunter, and Cupid.

One Night Ultimate Werewolf

A fast variant where the entire game is one night plus one day. Roles can swap during the night, so you might not even be who you started as. Games last 10 minutes.

Competitive (Sports) Mafia

A formalized tournament format popular in Russia. Exactly 10 players, 4 roles only (Citizen, Sheriff, Mafia, Don), timed speeches, strict rules. There's an international federation (FIIM) and championship tournaments.

Among Us

The 2020 video game that brought social deduction to mainstream audiences. It's not Mafia exactly, but the DNA is the same: impostors (Mafia) sabotage and kill, crewmates (Citizens) discuss and vote.

Yes. Mafia and Werewolf are the same game with different theming. Read more about the differences →
