Customer Testimonial
Hi, we certainly had a very different, but enjoyable night! Myself and one of my colleagues ran the night, but it was a lot of hard work. I would definitely recommend hiring one of your staff to do this, as I do not think we did it justice. Loved the character names and the printable invites, and everything that went with it. It was a great workplace Christmas party and everyone commented that they enjoyed it. Thanks Katie.

FAQ
How do you assign characters in a murder mystery game?
We recommend that you don't assign characters until the night of the event. This means that if people are sick at the last minute then the game will not be affected. You can give people suggestions as to the type of character they are e.g. come as a surgeon, dress as a hippie. This way they are dressed generically and can suit a wide range of characters. It is best to let your host put people into groups and assign characters on the night.
Do you need costumes for a murder mystery party?
Costumes are optional but highly recommended as they enhance immersion and make the event more fun and memorable.
How many people do you need for a murder mystery birthday party?
Boxed games are for 9 to 60 or 61 to 120 people.
Downloadable games are for 4 to 6, 7 to 10, 9 to 15, 16 to 30, 31 to 60 and 61 to 120 people.
How long does a murder mystery birthday party take?
Generally you would allow 2 to 3 hours.
If the party is a surprise birthday party then 2 to 3 hours after the surprise welcome.
Do birthday guests need acting experience?
Absolutely not! No acting experience is required. Players can participate at their own comfort level. The murder mystery places participants in groups and this is even better. The more gregarious players can take the spotlight while the more reserved players can share clues or sleuth away in the background.
Can I host a murder mystery birthday party at home?
Of course, murder mystery parties are commonly held at home and are ideal for birthdays. Home is free, easy to setup and you have full control over the space.
Can the birthday person play the game?
Yes!
Even if the birthday person runs it themselves, our games come with a step by step run sheet that guides you through every part of the game. The murderer is only identified in the full story so you can keep the game spoiler free until everyone finds out.
Can I make it a surprise birthday party?
If you’re planning a surprise birthday party, it’s best to bring in the murder mystery host after the surprise has taken place. Once the surprise happens, there is usually 30–45 minutes of meet and greet while the guest of the moment greets everyone. This makes it difficult to start the game straight away. For example, if the surprise is at 7:00pm, have your host arrive around 7:30pm so they can set up and begin once things settle.
If the host arrives before the surprise, they may be left waiting with little to do. Similarly, for workplace events, it’s better not to surprise your colleagues—letting them know in advance will lead to a more engaged and enjoyable experience.
Can children take part in a murder mystery birthday party?
Kids are fine and that is up to you. Older kids will often participate.
When should I serve the birthday cake?
Speeches and birthday cake should be completed at the end after the mystery has wrapped up.
Is a murder mystery good for a birthday party in London?
Yes, they make the day different and memorable and get the party pumping.
