Mafia
Mafia is a social deduction game in which players are secretly assigned roles as either mafia members or innocent townspeople. During night rounds, the mafia silently selects a player to eliminate. During day rounds, the surviving group debates and votes to remove a suspected mafia member. The game develops skills in reading group dynamics, persuasion, deception detection, and the ability to maintain a role under pressure. Mafia is widely used as a social warm-up and trust-building exercise in improv training and applied improvisation contexts.
Structure
The facilitator assigns roles secretly, typically through a card deal or by tapping players' shoulders while everyone's eyes are closed. A small minority of players (two to three in a group of ten to fifteen) are designated as mafia. The remainder are townspeople. One or two players may receive special roles: detective (who can investigate one player per round) or doctor (who can protect one player per round).
The game alternates between night and day phases. During the night, all players close their eyes. The facilitator calls for the mafia to open their eyes and silently agree on a player to eliminate. The mafia closes their eyes. Special roles perform their actions in the same manner.
During the day, the facilitator announces who was eliminated overnight. That player reveals their role and leaves the game. The surviving players debate who they believe is mafia. Anyone can make accusations, defend themselves, or argue for another player's innocence. After discussion, the group votes. The player with the most votes is removed and reveals their role.
The game continues until either all mafia members are eliminated (townspeople win) or the mafia equals or outnumbers the remaining townspeople (mafia wins).
The facilitator narrates the game, providing atmospheric descriptions of the night eliminations and managing the voting process during day rounds.
How to Teach It
How to Explain It
"We are going to play Mafia. Eyes closed. I am going to tap some of you: you are the mafia. During the day phase, the village argues and votes to eliminate a player. During the night phase, the mafia eliminates someone silently. I am the narrator."
Mafia is an effective warm-up for building group dynamics and social awareness. The game forces players to observe each other closely, read nonverbal cues, and make arguments based on behavioral evidence. These skills transfer directly to improv scene work.
The game teaches the skill of playing a role under social pressure. Mafia members must maintain their cover while being questioned by the group, which requires the same composure and commitment that demanding scene work demands. Townspeople must argue their innocence convincingly, which requires the same persuasive energy that strong initiations require.
Coach the facilitator role carefully. A good facilitator creates atmosphere through narration, manages the pace of debates, and ensures that quieter players have space to contribute. The facilitator's skill determines whether the game feels tense and engaging or procedural and flat.
The game can surface real group dynamics. Players who are natural leaders tend to dominate debates. Players who are less assertive tend to be voted out early on insufficient evidence. Use the post-game debrief to discuss these patterns and connect them to ensemble dynamics in improv: whose voice gets heard, who gets overlooked, and how the group makes decisions under uncertainty.
How to Perform It
The day-round debates are where the game's performance skills emerge. Players must read body language, detect inconsistencies in other players' arguments, and present their own case convincingly. The game rewards the same observational and persuasive skills that drive strong scene work.
Mafia members must act innocent while secretly coordinating their strategy through subtle signals and careful argument. This requires the ability to maintain a character (innocent townsperson) while pursuing a hidden agenda, a skill that transfers directly to playing characters with secrets in scene work.
The game's tension increases as the player count decreases. Later rounds produce more intense debates and higher-stakes votes. The facilitator should allow the tension to build rather than rushing through rounds.
The elimination mechanism means some players leave the game early. The facilitator should manage this by keeping eliminated players engaged as observers and by running the game at a pace that prevents long periods of inactivity for the eliminated.

Related Games
Murderer
Murderer is a social deduction game in which players move freely around a space while one secretly designated player eliminates others by winking at them. When a player receives a wink, they count silently to five and then perform a dramatic death. Surviving players attempt to identify the murderer before everyone is eliminated. If a player suspects the murderer's identity, they may make an accusation. A wrong accusation eliminates the accuser. The game sharpens observational awareness, rewards bold physical commitment in the death scenes, and builds ensemble energy through the combination of tension, deception, and theatrical dying.
Assassin
Assassin is a sustained social game in which each player is secretly assigned a target to "eliminate" through a discreet signal such as a wink, a specific word, or a light tap. Players circulate through the space or go about their normal activities while simultaneously hunting their assigned target and watching for signs that someone is hunting them. The game unfolds over an extended period, ranging from a single workshop session to an entire day or retreat. Assassin builds observational awareness, peripheral attention, and the ability to function on multiple levels of awareness simultaneously. The game is distinct from the exercise Assassins (a separate entry in the archive), which involves physical tag-style elimination in a defined space.
The Party
The Party is an improvisational game in which players take on character identities and interact at a simulated social gathering. In the most widely documented variant, each player is assigned a character they do not know (the identity is written on a card or otherwise concealed) and fellow guests drop subtle conversational hints to help the player deduce who they are. The game develops listening, subtext, and character awareness simultaneously.
Detective
Detective is a guessing game in which one player takes the role of an investigator while the remaining performers hold secret information about a crime, event, or scenario. The detective pieces together the story through questioning, observation, and deduction while the other performers communicate information indirectly through behavior, dialogue, and scene work rather than stating the answer directly. The game trains deductive reasoning, indirect communication, and the ability to convey information through subtext and physicality. Detective rewards both the guessing player's analytical skill and the ensemble's ability to provide clear, playable clues without giving the answer away.
Press Conference
Press Conference is a short-form game in which one performer plays a public figure fielding questions from other players acting as journalists. In the most common competitive variant, the central player is unaware of who they are portraying or what event they are addressing, and must deduce the situation from the questions while projecting confident authority. The game tests character commitment, subtext reading, and the ability to speak with conviction under uncertainty.
