Thirty suspects, one culprit. Our murder mystery games for 21–30 players are built for the big occasions — office parties, milestone birthdays, club socials and community events — where you want every single guest playing a character, not watching from the sidelines.
How murder mysteries work at this size
Start with a 4–20 player edition of your chosen story, then add its expansion pack to grow the cast to 30 named characters, each with their own booklet, backstory and secrets. The murderer is still drawn at random once everyone is in character, so hosts, organisers and even the boss play on equal footing.
At this scale the game becomes a proper event: guests work the room, alliances form across tables, and the accusation round gets theatrical. The host guide covers pacing for a crowd — splitting rounds, keeping evidence flowing and landing the reveal — and the included costume, menu and decoration suggestions make theming a venue straightforward.
Frequently asked questions
How do 25+ guests all take part?
Every guest receives a distinct character from the expanded cast — no sharing and no spare parts. Structured rounds keep the whole room moving toward the same reveal.
Are these games good for team building?
Excellent — mixed-department casting is a brilliant icebreaker, and the format rewards talking to people you don’t usually sit with. December bookings fill fast; see Christmas murder mystery games for seasonal picks.
What if we have more than 30 people?
Run two parallel investigations of the same story and crown the fastest table of detectives — or contact us and we’ll help you plan it. Running a ticketed or commercial event? You’ll need our commercial license.
Is a huge game hard to run?
The structure does the heavy lifting — allow around 3 hours and recruit one co-host per ten guests to hand out evidence, and the night runs itself.
