Play Mafia Online, Free
The classic Mafia party game in your browser: everyone's phone becomes their secret hand of cards, and the app is the moderator. Nothing to install, no accounts, 4–20 players.

Mafia Board Game is a free web app for playing Mafia (also known as Werewolf) with friends. One person starts a game at mafiaboardgame.org and gets a 4-letter room code with a QR code. Everyone else scans it on their own phone, picks a name, and takes a seat. The app then does everything a human moderator would: it deals secret roles, runs the night, announces the deaths, times the debate, and counts the votes. Nobody sits out, and no information ever leaks.
How it works — start to finish in under a minute
-
Start a game
Open the app in any browser. Pick your name and animal — the person who starts the game plays too. You'll get a room code and a QR code.
-
Everyone scans
Friends point their phone cameras at the QR code (or type the 4-letter code). No installs, no signups — each phone becomes that player's private, secret hand.
-
Night falls
One tap begins the game. From there it runs itself: secret roles are dealt, the mafia choose a victim, the town debates and votes — and at the end the app replays the whole hidden story.
What makes it different
- The app is the moderator. Classic Mafia sacrifices one player to narrate. Here the moderator role is fully automated, so the whole group plays.
- Actually free. No premium roles, no subscription, no ads interrupting the night.
- No downloads, no accounts. It's a web page. The barrier to a first game is scanning a QR code.
- Silent-night design. Every player interacts with an identical screen at night — even Villagers tap a decoy target — so nobody can tell who's really acting from thumb movements or timing.
- Self-advancing. Night, dawn, day timer, vote and verdict all pace themselves. Even the host just plays.
- The reveal. When it ends, the app reconstructs the full story: every save by the Angel, every investigation by the Sheriff, every lie.
Compared to the usual ways of playing
| Playing cards + a narrator | Mafia Board Game | |
|---|---|---|
| Who runs the game | One player sits out to moderate | The app — everyone plays |

| Information leaks | Rustling, peeking, narrator slip-ups | Actions happen silently on identical phone screens |
| Rule disputes | "Wait, who died? Who saved whom?" | Deterministic engine + a full end-of-game timeline |
| Cost | Free (needs cards) | Free |
In one room — or over a video call
Mafia is at its best in one room, faces visible, accusations flying. That's what this app is designed for: the phones handle the secret parts while the arguing happens out loud.
But the room code works from anywhere. If part of the group is remote, they can join with the same 4-letter code, the host can screen-share the Table view on the call, and the daytime debate simply happens over video. Hybrid game nights work fine.
Round up 4+ friends and deal the cards
It takes about ten seconds to get a room code on screen.
Play Mafia free →Frequently asked questions
Is it really free?
Yes — completely. No downloads, no accounts, no paid roles, no ads in the middle of the night phase.
Do we all need to install something?
No. It runs in the browser on every device. The host starts a game; everyone else scans the QR code or types the room code.
How many players does it support?
4 to 20 in a single game. The role mix auto-balances as the group grows — more players, more mafiosi.
iPhone, Android, laptop?
All of them. It's a mobile-first web app — anything with a modern browser works, including a TV for the shared Table screen.
Can remote friends join?
Yes. The room code works from anywhere; pair it with a video call and screen-share the Table. The game itself doesn't care where players sit.
Is this the same game as Werewolf?
Yes — Mafia and Werewolf are the same game with different themes. If your group says "Werewolf," everything here still applies.
