How to Play Murder in the Dark

By Jaques of London · Est. 1795 · Updated 2026-08-17

Murder in the Dark is a social deduction and bluffing game for five or more players, best suited to large groups of eight to fifteen. The Murderer must eliminate a victim undetected in a darkened room while all other players lie in wait, and the Detective must then piece together who did it from witness statements and alibis. The combination of physical suspense, darkness, and face-to-face bluffing makes it gripping in a way few parlour games can match.

It is traditionally played indoors at parties, sleepovers, and youth groups, usually in the evening when rooms can be properly darkened. The game requires no board, no screen, and no prior knowledge, which is precisely why it has stayed popular across generations. A round takes only a few minutes, so groups typically play several in succession.

A little history

The exact origins of Murder in the Dark are unclear. It belongs to a broad family of social deduction party games that became fashionable in Britain and North America during the early twentieth century, and references to games with similar mechanics appear in etiquette and parlour-game books from the 1920s and 1930s. It is traditionally grouped alongside games such as Wink Murder and is widely regarded as a forerunner of later structured social-deduction formats. How or where the specific rules became standardised is not reliably documented.

Setting up

1. Count out one card per player. One card must be an Ace (the Murderer), one must be a King or Queen (the Detective), and all remaining cards are number cards (Victims).
2. Shuffle those cards face down and deal one to each player. Players look at their card in secret and say nothing.
3. The player who drew the Detective card identifies themselves aloud immediately and leaves the room, or stands in a clearly designated spot away from the group with eyes shut.
4. All remaining players note whether they are the Murderer or a Victim. The cards are pocketed or set aside.
5. Someone turns the lights off, or the group moves into the darkened area. Play begins.

How to play

1. Once the lights are out, all players (except the Detective, who waits outside or in place with eyes closed) move slowly and silently around the darkened room.
2. The Murderer chooses their moment, finds a player by touch, and kills them by squeezing their hand or placing both hands firmly on their shoulders. The Murderer may move around as long as they wish before striking.
3. The victim waits a realistic beat of two to three seconds after being touched, then screams or shouts 'Murder!' as dramatically as they like. This signals the kill.
4. Everyone freezes exactly where they are the instant the scream is heard. Nobody moves, speaks, or changes position after the scream until the Detective arrives.
5. The lights are switched on (or the Detective enters the room). The Detective examines the scene: the victim lies or sits down on the spot and plays dead for the remainder of the round.
6. The Detective questions every surviving player in turn. Each player must answer every question truthfully, with one strict exception: the Murderer alone is permitted to lie.
7. All non-Murderer players must tell the truth at all times, including confirming or denying whether they saw or heard anything, and where they were standing when the scream occurred.
8. The Detective has one formal accusation. They may question players as many times as they like before making it, but once they say 'I accuse [name]' the round ends.
9. The accused player reveals their card. If the Detective is correct, the Detective wins the round. If incorrect, the Murderer wins the round.
10. Shuffle and re-deal for the next round. Rotate so different players get the chance to be Detective and Murderer across the session.

Winning and scoring

There is no single cumulative winner across a full session unless the group chooses to keep a tally. Within each round, the Detective wins by correctly identifying the Murderer in a single accusation. The Murderer wins if the Detective accuses the wrong person, or if the Detective gives up without accusing anyone. If keeping score across rounds, award one point to the Detective for a correct accusation and one point to the Murderer for a successful deception; the player with the most points after an agreed number of rounds wins the session.

The fine points

The most common dispute concerns what counts as the Murderer's kill touch. The standard ruling is that the Murderer must make deliberate, unambiguous physical contact with the victim, not merely brush past them in the dark. If both players contest whether contact occurred, the victim's account takes precedence. A Murderer who accidentally touches someone and is immediately called on it by that person is deemed to have made the kill, so Murderers should move carefully.

A second frequent question is whether non-Murderer players may stay silent or say 'I don't know' when questioned. Staying silent is not the same as lying: players may legitimately say they did not see or hear anything if that is true. What they cannot do is state a false location, name a false suspect with conviction, or deny being in a place they were. The Murderer, by contrast, may answer any question however they choose. If a player is caught in a provable lie and they are not the Murderer, the group should rule that the Detective may discount their testimony but may not automatically accuse them.

How to win more often

• Murderer: strike early in the dark phase before players cluster together. Lone victims are far easier to reach quietly and give you more time to move away before the scream.
• Murderer: after the scream, freeze in a position that places you away from the body and close to another cluster of players so your alibi feels natural.
• Detective: before questioning begins, scan the room layout and note who is standing unusually far from the body for the space available. Distance can indicate movement after the scream, which is a rules breach worth noting.
• Detective: ask every witness what they heard before the scream, not just after. The Murderer sometimes moves furniture or bumps into things; other players who genuinely heard nothing are more credible as Victims.
• All players: if you are a Victim, remember exactly where you were standing when the scream happened. The Detective will ask, and hesitation or a vague answer makes you look suspicious even when innocent.

Variations

Multiple Murderers

Deal two Ace cards into the mix for larger groups of twelve or more. The two Murderers do not know each other's identity at the start, but may deduce it during questioning. Either Murderer may make the kill. The Detective must name both Murderers correctly to win; naming only one counts as a win for the surviving Murderer.

Wink Murder (Lights-On Version)

All players sit in a circle with the lights fully on. The Murderer kills by making deliberate eye contact with a victim and winking. The victim counts silently to three, then dies dramatically. The Detective sits within the circle and watches for the wink in real time. This version suits younger children or spaces where darkening a room is not practical.

Alibi Cards

Before the lights go out, each non-Detective player is quietly handed a location card from a preset list: Kitchen, Hallway, Corner, Window, and so on. Players must try to be near their stated location when the scream sounds. This gives the Detective concrete alibis to verify or disprove, and raises the stakes for the Murderer, who must move to a different location from the one on their card before striking.

Timed Detective

The Detective is given a strict three-minute questioning period before they must accuse or forfeit. Use a phone timer visible only to a neutral timekeeper. This variant prevents the questioning phase from dragging and puts real pressure on the Detective's decision-making, rewarding Murderers who give longer, more plausible answers.
