Customer Testimonial
Good morning! We ordered the premium Tracy Gang box for our 1920’s themed staff party. The box came with everything we needed to guide us through hosting a great night! Everyone loved the personalised name badges. The amount of information is daunting to begin with, which is why you need to familiarise yourself with the story etc. The party was a hit, the clues weren’t giving everything away so not every team was able to guess the correct murderer, which is great. Very detailed kit, which we were very happy with. Thank you!

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.
