Murder mystery for 15 players

Fifteen players turns a murder mystery into an event. Fifteen suspects in one room is a cocktail party with a body count of one, and it needs more planning than a dinner for eight: more space, a longer clock and a case built so that nobody gets lost in the crowd. The payoff is atmosphere: at fifteen there's always a huddle to join, a rumor to chase and someone glancing over a shoulder.

Big Party: up to 20 guests for $39, one time.

Give a fifteen-player game 150 minutes. Arrival, the opening scene and introductions take about 20; each of the three clue rounds gets 25 to 30, so every cluster has time to scheme and still mingle; accusations take 20; and the reveal and awards share the last 25, because a big room wants a big finish. Have drinks and nibbles ready at arrival and a buffet open from round one, since a seated dinner for fifteen slows everything down.

The case itself should be built in layers. In the Old Hollywood awards-night example below, four side plots (a rigged winners' envelope, a stolen screenplay, a gossip columnist's blackmail file and a studio contract dispute) each tie three or four characters together, and all four collide with the murder. Each cluster has a small mystery of its own to chew on in round one, and the threads cross in rounds two and three. Fifteen guests need the Big Party plan, $39 one-time for up to 20, and every case includes 2 standby characters for walk-ins.

15 players,
how it works

Every character sits in one of four side plots of three or four people, and five or six of them also carry the strongest motives for the murder. Spreading those core suspects across different plots keeps any one cluster from owning the solution.
Six to eight red herrings work at fifteen. Give every side plot at least one, and make sure each is explained before accusations so nobody votes on a dead end.
Give each side plot its own small payoff in round one or two: a confession, a found item, a solved puzzle. Early wins keep fifteen people engaged while the main case builds.
Phones make fifteen far easier to run, since objectives, clue reveals and the Evidence Locker live on each guest's own screen. If you print the optional kit instead, allow an extra hour of prep to sort booklets and clue cards, and print name tags either way.

Tips for 15 players

Name tags with character names are essential at fifteen. Nobody remembers fifteen aliases by round two, and a tag turns "you, in the hat" into a proper accusation.
Give the narrator real volume: a TV with decent speakers, or a Bluetooth speaker turned up for each round's opening. Fifteen chatting guests will drown out a laptop.
Turn arrival into the introductions. Lay a red runner by the door and give each guest 10 seconds on the carpet in character while someone snaps a photo.
If you're playing a suspect, hand the door and the drinks to a friend for the night, so you aren't refilling glasses in the middle of round two.
Spread out across two or three rooms, but choose one gathering spot for round openings so everyone hears the narrator together.

Questions

Which plan do I need for 15 players?

Big Party: $39, one-time, for up to 20 guests, with no subscription. The $24 Party plan stops at 12 guests.

How long does a murder mystery for 15 people take?

Plan 150 minutes from the opening scene to the awards, plus 20 to 30 minutes of arrival time. The extra half hour compared with smaller games goes to longer rounds, accusations and a reveal the whole room can follow.

What if someone cancels?

Re-casting is free until 24 hours before the party, and only the affected character and clue assignments change. If someone is a no-show on the night, mark them absent and their must-share clues move to someone who is there.

What if extra people show up?

Every case includes 2 standby characters for surprise guests, ready to hand out during arrival.

How much space do 15 players need?

Less than you'd think. A living room plus an open kitchen or dining area works, because guests stand and mingle for most of the game. Just clear one spot where everyone can gather for round openings and the reveal.
