How to Play Mafia as a Moderated Party Game

How do you play Mafia as a party game?

One moderator secretly assigns players to the Mafia or Town. Each night, everyone closes their eyes while the Mafia chooses one player to eliminate, the Doctor protects one player and the Detective checks one player’s alignment. Each day, the moderator announces the night result, living players discuss, then cast secret ballots to eliminate one suspect. Town wins by removing every Mafia member; Mafia wins when its living members equal the living Town.

That is the complete loop. The difficult part for a new group is not bluffing; it is having a moderator who performs every action in the same order and checks for a winner before starting another phase.

Which roles belong in a beginner game?

Use these roles for nine active players plus one non-playing moderator:

• Two Mafia: know each other and jointly select one non-Mafia target each night.
• One Detective: checks one other living player each night and receives a Mafia/not-Mafia answer.
• One Doctor: protects one living player each night, including themselves, but cannot protect the same person on consecutive nights.
• Five Townspeople: have no night action; they discuss and vote during the day.

The Detective, Doctor and ordinary Townspeople are all members of the Town team. A Detective result of “not Mafia” does not distinguish the Doctor from an ordinary Townsperson.

With seven or eight active players, use one Mafia, one Detective, one Doctor and fill the remaining places with Townspeople. With 10 to 13 active players, use two Mafia and the same two special Town roles. Do not add a third Mafia or a catalogue of special powers to a first game.

Cornell University’s team-building guide uses cards for Mafia, police, a Doctor and Townspeople. MIT OpenCourseWare likewise describes role cards, a moderator, Mafia and villagers, with Medic and Detective as common additional roles. The exact counts and restrictions above are Carolix’s beginner setup.

What materials and preparation does the moderator need?

Prepare one role card per active player, a private night-action sheet, pens and small ballot slips. Mark every seat with a visible number or write a short player list in seating order. The moderator needs to identify a target silently without saying a name at night.

Seat active players in a circle. The moderator stays outside it with a clear view of hands and faces. Keep the room lights on. Players close their eyes during the night; nobody uses a blindfold or moves around the room.

Before dealing, explain:

• the complete role list;
• the fixed night-action order;
• whether eliminated roles are revealed—this version says yes;
• the Doctor’s no-consecutive-repeat rule;
• secret-ballot voting and no-elimination ties;
• both win conditions; and
• conduct limits for discussion.

Shuffle and deal one card face down to each active player. Everyone privately checks their role and returns the card face down in front of them. The moderator records each role beside the seat number before starting.

If you need a shorter game before introducing hidden roles, start with one of these party games for small groups.

What are the winning conditions?

Town wins immediately when no living Mafia members remain. Mafia wins immediately when the number of living Mafia members equals the number of living Town members. At equality, Mafia can control or block the day vote, so another cycle is unnecessary.

Check these conditions after every day elimination and every announced night elimination. Do not begin discussion, call another night role or allow a farewell accusation before the check.

The game can also end if the moderator makes an unrecoverable error or the group agrees to stop. That is an abandoned game, not a win for either team.

What does the moderator say on the first night?

Use the same script every night. Parenthetical text is an action for the moderator, not something to read aloud.

“Night begins. Everyone close your eyes and keep your hands still.”

“Mafia, open your eyes and recognise one another.” (On later nights: “Living Mafia, open your eyes.”)

“Mafia, silently agree on one living non-Mafia target and point now.” (Record the target only after every living Mafia member indicates the same person.)

“Mafia, lower your hands and close your eyes.”

“Detective, open your eyes and point to one other living player.” (Record the choice. Nod yes for Mafia and no for every Town role.)

“Detective, close your eyes.”

“Doctor, open your eyes and point to one living player to protect.” (If the Doctor repeats the previous night’s choice, silently shake your head until a legal target is chosen.)

“Doctor, close your eyes.”

“Morning begins. Everyone open your eyes.”

Give the Mafia 30 silent seconds to agree. If they do not indicate one unanimous legal target, record no Mafia elimination for that night. Mafia may not target one of their own members.

If a night role has been eliminated, read that role’s wake and sleep lines anyway, pause for the usual few seconds, then continue. Skipping a line tells living players that the role is gone.

Cornell’s guide uses the same broad sequence: Mafia wake and choose unanimously, police investigate with a silent nod or shake, the Doctor selects a protection target, then morning begins. Its published order places police before Doctor; this script keeps that order.

What does the moderator announce at dawn?

Compare the Mafia target with the Doctor’s protection:

• If they match, say, “Morning begins. No player was eliminated overnight.”
• If they do not match, name the Mafia target and say, “You are eliminated. Please reveal your role card and remain silent.”
• If Mafia selected no legal target, announce no overnight elimination.

Do not reveal who was protected, investigated or selected unsuccessfully. Do not invent a story that hints at a role or seat. The moderator reports only the outcome.

After any elimination and role reveal, update the living-player list and check the win conditions. If neither team has won, start the day discussion.

How should daytime discussion work?

Set a four-minute timer. Every living player may speak, accuse, defend or claim a role. Mafia may lie about their identity; hidden information and bluffing are part of the game. Eliminated players remain silent and do not react.

Keep claims inside the game. Players may discuss votes, statements, pauses and claimed night information. They may not use personal insults, pressure someone to disclose private experiences, search devices or treat real-world identity as evidence.

The moderator manages turns only when people talk over one another. Give a repeatedly interrupted player up to 30 uninterrupted seconds, then reopen discussion. At the timer, finish the current sentence and move to nominations.

MIT’s classroom discussion of Mafia describes night role cues followed by free daytime speech, suspicions and accusations. It also demonstrates how much voting procedure varies. The written-ballot method below is this article’s declared version.

How do nominations and voting work?

The moderator asks each living player, once in seating order, to nominate one other living player or pass. A nomination needs no second. Write each unique nominee where everyone can see it.

After nominations close, each nominee gets 30 seconds for a defence in the same seating order. No questions or interruptions occur during a defence. Then every living player, including nominees, receives one blank ballot.

Each voter privately writes one nominated player’s seat number or writes abstain, folds the slip and hands it to the moderator. A ballot for a non-nominee, an eliminated player, more than one person or an unreadable choice counts as an abstention.

The moderator opens and reads every ballot aloud, records the tally, then announces one result:

• One nominee has the most votes: eliminate that player and reveal their role.
• Two or more nominees tie for the most votes: eliminate nobody.
• Everyone abstains or no one is nominated: eliminate nobody.

There is no immediate runoff in the base rules. A tie or no-elimination result ends the day and moves the game to its win check, then night. This prevents repeated votes from turning one day into an unlimited attempt to force a result.

Cornell’s version uses nomination, defence and a majority vote, and also permits a day to end without an elimination. Carolix uses a highest-total secret ballot with ties producing no elimination; announcing that distinction before play is essential.

What happens to eliminated players?

An eliminated player reveals their role card, folds their arms and remains seated or moves to a nearby observer area. They may keep their eyes open at night, but cannot speak, vote, gesture, show notes or react to actions and claims.

Eliminated players do not reveal private night information beyond the role card. A Detective cannot announce their past results after elimination, and a Mafia member cannot identify their teammate.

If an eliminated player accidentally gives information, the moderator states what happened without interpreting it and continues if the game remains playable. Deliberate or decisive disclosure may require abandoning the game.

How does the next cycle begin?

After the day result, update the living list and check for a winner. If the game continues, collect unused ballot slips, clear the public nomination list and begin the same night script from the top.

The Doctor’s previous protection remains recorded between nights. Detective results remain private to that player. Mafia members retain knowledge of one another even after a teammate is eliminated, but only living Mafia wake and choose the next target.

Repeat night, dawn, discussion and ballot until one win condition is met. The moderator reveals all remaining roles at the end.

How should the moderator handle night mistakes?

Use a flat ruling rather than improvising an advantage:

Record actions before moving to the next line. The moderator should never rely on remembering three pointed-at seats after everyone wakes.

How do you keep the game comfortable and safe?

Keep everyone seated or standing still in a clear, lit room. No player moves around with closed eyes, uses a blindfold, touches another person to perform an action or acts out an elimination. Remove bags, drinks and cables from the circle.

Use out, eliminated and Mafia target in the moderator script rather than narrating physical harm. A group that dislikes the theme can rename the teams Spies and Agents without changing any mechanic.

Discussion permits deception about game roles, not personal attacks. The moderator pauses immediately if a player asks to stop or the tone becomes personal. Anyone may leave the game without explaining; the moderator abandons or redeals rather than inventing a replacement role mid-cycle.
