Murder Mystery
Murder Mystery is a long-form or short-form game in which the ensemble improvises a classic whodunit scenario, complete with a victim, suspects, clues, red herrings, and a dramatic reveal. The audience often suggests the victim, the setting, and the murder weapon, providing the raw material from which the ensemble constructs the mystery. The game demands careful narrative tracking, ensemble coordination, and the ability to plant information early that pays off in the final act. It rewards performers who can maintain the balance between genre fidelity and comedic invention.
Structure
The game begins with audience suggestions: a victim (name and occupation), a location, and a murder weapon. The ensemble establishes the scenario with an opening scene in which the victim is discovered and a detective figure begins the investigation.
The detective interviews suspects. Each suspect is played by a different ensemble member who establishes their character's relationship to the victim, their alibi, and their motive (or lack of one). Each interview plants clues and red herrings that the audience tracks.
Between interviews, the ensemble plays flashback scenes showing the relationships between the suspects and the victim before the crime. These scenes provide context, deepen characters, and embed the clues that the detective will use in the final reveal.
The investigation builds toward a climactic confrontation in which the detective gathers all suspects and reveals the solution. The reveal must account for the clues planted throughout the show, using information that was visible to the audience but not immediately obvious. The best reveals produce a reaction of satisfying recognition: the audience sees how the pieces fit together.
Variations include audience-voted murder mystery (the audience decides which suspect is guilty, and the detective must justify the audience's choice), unsolved murder mystery (the mystery deepens rather than resolves, creating a deliberately ambiguous ending), and musical murder mystery (the investigation is punctuated by songs from the suspects).
How to Teach It
How to Explain It
"You are creating a murder mystery. There is a victim, a detective, suspects, and a solution. The audience does not know who did it until the end. Neither do the performers. The story discovers itself."
Murder Mystery is an advanced game that develops narrative tracking, callback skills, and ensemble coordination. Use it with performers who have strong foundational scene work skills and the ability to track information across multiple scenes.
Coach the ensemble to plant specific, memorable clues rather than vague suspicions. A glove found at the scene is a specific clue. A character who "seems suspicious" is not. The specificity of the clues determines the quality of the reveal.
The game teaches the skill of collaborative storytelling with a fixed endpoint. The ensemble must build toward a reveal without knowing what that reveal will be. This requires a special kind of trust: faith that the ensemble will generate enough material that a coherent solution will emerge.
Use rehearsals to practice the reveal specifically. Run exercises in which the detective must construct a solution from a set of randomly generated clues. Building this synthesis skill prepares the detective performer for the show's most demanding moment.
How to Perform It
Narrative tracking is the game's essential skill. Every performer must remember what clues have been planted, which suspects have been established, and what information the audience holds. A reveal that contradicts earlier clues breaks the audience's trust. A reveal that ignores planted clues wastes the ensemble's earlier work.
The detective character carries the show. The performer playing the detective must listen to every scene, track the emerging clues, and construct a coherent solution from the ensemble's contributions. This role requires the ability to synthesize improvised material in real time, which is one of the most demanding skills in long-form improv.
Genre conventions help the ensemble. The whodunit format has a clear arc (crime, investigation, suspects, red herrings, reveal) that provides structural guardrails. Performers who know the genre's conventions can use them as a shared framework, simplifying coordination and giving the audience familiar signposts.
The game benefits from a balance of comedy and genuine mystery. A show that plays entirely for laughs loses the tension that makes the reveal satisfying. A show that plays entirely as a straight mystery without comedic moments misses the improv audience's expectations.

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.
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.
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.
Mystery Word
Mystery Word is a short-form game in which performers play a scene while one performer -- unbeknownst to the others -- has been given a specific secret word that they must work into the dialogue naturally and without drawing attention to it. The rest of the performers and audience try to identify when the mystery word has been successfully used, creating a dual layer of engagement: the scene itself and the detective puzzle of watching for the hidden word.
Before or After
Before or After is a short-form game in which performers present a scene, then the audience calls out whether they want to see what happened "before" or "after" the events just depicted. The performers create a new scene that logically connects to the original, revealing backstory or consequences that recontextualize what the audience already witnessed. The game can cycle through multiple rounds, with the audience driving the story forward or backward in time. Before or After trains narrative construction, temporal awareness, and the ability to expand a story in either direction while maintaining internal consistency. The game rewards performers who plant details in early scenes that pay off when the timeline shifts.
