Someone here is lying
The Mafia party game where everyone gets to play
Create a private room, pass around a QR code, and start. Mafia Night deals the secret roles and runs every night action and vote, so no friend has to sit out as narrator.
Free · 4–16 players · no account · no download
From phones out to first night
Start in four small steps
There is no registration flow, public matchmaking, or deck to prepare. The conversation stays in the room; phones handle only the private information.
Create a room
Choose Mafia or Werewolf, add a display name, and receive a four-character room code.
Invite the group
Friends scan the host's QR code or open the invitation link on their own phones. No one needs an account.
Reveal roles privately
Each player presses and holds their role card to peek, then releases to hide it from nearby shoulders.
Talk in person, act by phone
Night choices and ballots happen privately on-screen. Accusations, alibis, and persuasion happen face to face.
The full game loop
What the app handles—and what it leaves to people
Mafia works because people must read each other. The software should protect secrets and settle rules, not replace the table talk.
Night actions
Mafia members select a target, the Detective investigates, and the Doctor protects. Teammate choices coordinate silently.
Dawn results
The group learns whether someone died or a save succeeded. Eliminated roles are revealed, preventing rules arguments.
Open discussion
Set your own pace. The host calls the vote only when the group has made its cases and is ready to decide.
Private ballots
Every living player votes on their own device. A tie—or more abstentions than the leading suspect—eliminates nobody.
Ghost view
Eliminated players can see all roles and night moves while the living remain in the dark. Ghosts still cannot vote.
One-tap rematch
The same group can play again without rejoining. Roles are freshly shuffled, so last round's trust means nothing.
Balanced by default
Recommended Mafia roles by player count
The default deck updates as friends join. It always includes a Detective, adds a Doctor at five players, and increases the Mafia team at six, ten, and fourteen players. Hosts can still customize the deck.
| Players | Mafia | Detective | Doctor | Villagers | Best for |
|---|---|---|---|---|---|
| 4 | 1 | 1 | 0 | 2 | A quick teaching round |
| 5 | 1 | 1 | 1 | 2 | Learning protection and investigation |
| 6–9 | 2 | 1 | 1 | 2–5 | The strongest all-purpose setup |
| 10–13 | 3 | 1 | 1 | 5–8 | Longer discussions and vote analysis |
| 14–16 | 4 | 1 | 1 | 8–10 | Large parties with confident players |
First game? Keep the automatic deck. Add the Jester, Vigilante, or Serial Killer only after everyone understands the basic Town-versus-Mafia win conditions. The roles guide explains the exact behavior of every role.

Common questions
Mafia Night FAQ
What is Mafia Night?
Mafia Night is a free online multiplayer version of the Mafia social deduction party game. Friends join one private browser room, receive hidden roles on their phones, talk together, and vote; the game resolves night actions and win conditions so every person can play.
Is Mafia Night free, and do players need accounts?
It is free to play. There is no registration, profile, or app installation. Players choose a temporary display name and avatar for the room.
How many people can play?
A room supports 4–16 active players. Six to ten is the easiest range for a lively discussion without making each day too long.
Does anyone need to be the narrator?
No. The browser deals roles, asks eligible roles for night actions, reveals dawn results, collects votes, and checks win conditions. The host controls pacing but also receives a secret role and plays normally.
Can we play over a voice or video call?
Yes. Share the invitation link instead of the QR code and keep a voice channel open for discussion. Each player still uses their own browser for secret actions.
What happens if a phone locks or loses connection?
The game remembers a private reconnect token in that browser. Reopening the same room link usually restores the player. The game does not wait forever for a disconnected phone's night action or ballot.
How long are room details kept?
Rooms live in server memory and are automatically removed after two hours without activity. There is no account history or permanent game database.
Is Werewolf a separate game?
It is the same rules engine with village language: Mafia become Werewolves, the Detective becomes the Seer, and the Doctor becomes the Healer. A host can switch themes in the lobby.
Where can I report a bug or suggest a role?
Use the contact page. Include the device/browser, what phase the room was in, and what you expected to happen; never send a private room token.
Built around real game-night friction. Mafia Night exists to solve one specific problem: the friend who explains the rules should not also be forced to sit out. Our public guides document the same rules implemented in the game, including unusual edge cases such as ties, abstentions, disconnections, and protection order.
