Who's the Mafia?
Anyone could be lying.
The Mafia eliminate players in secret at night. The town investigates, protects one another, and votes. You never have the whole story.

What is Who's the Mafia?
Who's the Mafia? is a hidden-role game. Most of the table is Town. A few are Mafia. The town has to find them before the numbers are even.
Nights are private. Mornings are public. The talk happens in the room, and the server decides the kill, the save, the vote, and the winner.
How to play
A round is a night, a morning, a talk, and a vote. That repeats until one side wins.
02
Read your role
Only you see it. Mafia see their teammates. Everyone else starts with less. This screen lasts a few seconds, and the host can continue.
03
Survive the night
Mafia choose someone. The Detective investigates one living player. The Doctor protects one player. Villagers wait. Night ends when those actions are in, or when the clock runs out.
04
Read the morning
The town hears who died, or that nobody did. A saved player is announced as nobody dying. The town does not hear who was protected.
05
Talk
Use the room chat and voice. The game does not tell you who is lying. When the discussion clock ends, voting opens.
06
Vote
One vote for a living player, and you cannot change it. You cannot vote for yourself. A tie, or no votes, eliminates nobody.
Night, morning, day
The same three beats, every round. The public record keeps each one, newest first.
Night
The town is asleep. Mafia, the Detective, and the Doctor each make one choice. Villagers watch the clock.
Morning
The town learns who was killed, and their role if the host left that on. A protection is never named.
Day
Talk, then vote. Who has voted is public. The tally stays hidden until the vote closes.
Roles
Four roles. Mafia know each other. Town does not. The Detective and the Doctor can be turned off before the match.
Mafia
- See the other Mafia
- Choose one living player each night
- Cannot choose yourself
- Win when the living Mafia match the living town
Detective
- Investigate one living player each night
- Learn only Mafia or not Mafia
- Never learn the exact role
- The result stays on your screen
Doctor
- Protect one living player each night
- May protect yourself, unless the host turns that off
- Cannot protect yourself two nights in a row, unless the host allows it
- A save is announced as nobody dying
Villager
- No night ability
- Talk, accuse, and vote with the town
- Win when no Mafia remain
- A dead villager still watches the public board
Rules
Open a group for the detail. The short line is the rule that matters.
RolesShowHideThe server deals one hidden role to each seat.
- Auto is 1 Mafia for 5–6 players, 2 for 7–9, and 3 for 10–12.
- The host can set 1, 2, or 3 Mafia only when Mafia would still be fewer than Town at the start.
- Detective and Doctor are on by default. Turning one off makes that seat a Villager.
- Mafia see their teammates. Nobody else sees a role list.
- A dead player and a spectator see the public board only: phase, who is alive, the public record, and the clock.
NightShowHideOne choice each. The night resolves when the required actions are in, or the clock ends.
- Every living Mafia submits a target. If they agree, that player is the kill. If they disagree, the earliest valid choice is the kill.
- No Mafia choice means nobody is killed.
- The Detective investigates one other living player and learns Mafia or not Mafia.
- The Doctor protects one living player. A protected target survives, and the morning says nobody died.
- The default night clock is 30 seconds. The host can pick 20, 30, 45, or 60, or any time from 5 seconds to 60 minutes.
Morning and dayShowHideThe town hears the result, talks, then votes once.
- With roles revealed on death, the morning names the role. With that off, it names only the player.
- Discussion uses the room chat and voice. The default is 60 seconds. Fast is 30 seconds of talk and 20 seconds to vote.
- Voting is one ballot. You cannot vote for yourself, and you cannot change it.
- Who has voted is public. The target and the tally stay hidden until the vote closes.
- A tie, or a clock that ends with no votes, eliminates nobody.
WinningShowHideThe match ends the moment one side meets its condition.
- Town wins when no Mafia remain.
- Mafia wins when the living Mafia are at least as many as the living town.
- That check happens after the morning and after the vote.
- At the end, every role is revealed. The winners are everyone on that side, living or dead.
- There are no points and no bots.
How it ends
There is no score. The side that meets its condition wins, and every role is shown.
Town wins
No Mafia are left. Everyone on the town side wins, including players who were already out.
Mafia wins
Living Mafia equal or outnumber the living town. They do not need a majority of the original table.
A tie vote
Nobody is eliminated. The night comes again, unless Mafia already match the town.
What the host can change
These are set in the room before the match. The board teaches the rest.
Preset
Classic is 30 seconds at night, 60 seconds to talk, and 30 seconds to vote. Fast is 20, 30, and 20.
Mafia count
Auto, 1, 2, or 3. Auto follows the table size. A count that would already let Mafia win at the start is rejected.
Detective and Doctor
Each can be turned off. That seat becomes a Villager. The Doctor’s self-protect, and protecting themselves two nights in a row, are separate switches.
Reveal roles
On by default. A death then names the role in the morning or after the vote. Off names only the player. The final screen still shows every role.
Clocks
Night, discussion, and voting each have their own time. Role reveal, morning, and the vote result last 5 seconds. The host can continue those three.
Seats
One player per seat, from 5 to 12. The host sets the count. People who do not sit can watch. The host can pause during the match, and every clock stops. There are no bots.
