Play a who dunnit game

If you've never played a who dunnit game – it's a game you play at a party, where all the players hear and give evidence to solve clues so they can work out who amongst them is the murderer 🔪🩸.

The game can be spread over several rounds and can take place as a murder mystery night, murder mystery dinner party – or even a whole murder mystery weekend.

Who dunnit games are often themed – and players are encouraged to dress up in character.

How do you play a who dunnit game?

There are a few variants of who dunnit games you can play.

The most common are:

Scripted Who Dunnit Dinner Party Game

Players are given a script to read which includes character background information, questions to ask and general murder plot dialogue.

Players will usually stay in the same place for the duration of the who dunnit game.

The guided nature of the script makes this option a great ice breaker for small groups that don’t know each other well.

A scripted game works well for small groups of 6–20 guests.

Interactive Who Dunnit Event Murder Mystery Game

These murder mystery games rely on cast members.

Players don’t have a script but instead, mingle, interact and even interrogate cast members.

The characters are free to roam in a less linear fashion.

There are often sub-plots and character goals running alongside the main whodunnit murder mystery.

An interactive game works well for 12 or more detective guests – up to large groups of up to 200.

Where can I host my who dunnit game?

People imagine playing a who dunnit game in a spooky mansion or old steam train.

But as long as the murder mystery script is good and the players are keen – almost anywhere will do.

Some places you could play your who dunnit game are:

  • At home as a dinner party or friends get together
  • In your back garden
  • At work in the office
  • At your local Scout or Girl Guides group
  • At your Church group
  • At your local youth group
  • At school at playtime
  • A get together at the village hall
  • Virtually online – via Zoom, FaceTime, Google Meet, or any other video call service

Did you know?

It’s believed murder mystery game’s evolved from the ‘Wink Murder’ game in from the early 1900’s – where a pre-selected participant could kill other players by winking at them 😉

How long does a who dunnit game take to play?

You’ll typically need to set aside 1–2 hours to play a scripted who dunnit game.

Though you can easily double that time if you’re playing it as part of a murder mystery dinner party.

If you’re pushed for time – you can whizz through much quicker. It’s up to you to dictate the pace.

An Interactive game can take much longer – sometimes spanning whole a murder mystery weekend.

Who dunnit game characters and costumes

To get in the murder mystery mood players may want to dress in character.

What players wear usually depends on the theme of the who dunnit game.

You don’t have to go down the typical Sherlock Holmes, Hercule Poirot, Miss Marple or Colonel Mustard costume route.

You could theme it for a specific occasion; a Christmas murder mystery, a Halloween murder mystery party – or even a murder mystery hen party!

When you build a personalised You Dunnit who dunnit game — players are emailed information about their character so they know who they’re playing and what to wear.
