Customer Testimonial
Hi team! We used the Tracy Gang 1920s party for a mid-year work function and had the best time! I loved the print-and-go format, the ability to add games was great and lightened the mood. We self-hosted and the information provided made this really easy. Thanks for a fabulous evening. Anna.

FAQ
Are murder mystery games difficult to run?
No, most games are designed to be easy to run with clear instructions. Preparation usually involves following a step by step procedure, making it accessible for beginners.
What sort of venue do I need?
Because murder mysteries involve playing games and your guests doing lots of fun and silly things, they need a quiet venue with lots of space.
You can hold a murder mystery at home or in a function venue. Try any venue which:
- Is completely private i.e.: not a restaurant or public spaces.
- Is very quiet i.e. no bands, piped music or DJ's next door.
- Has lots of room to move around. Imagine all your guests standing in a circle.
- You need one central area big enough for all guests at one time.

The games are naturally engaging but there are a number of tricks of the trade.

- For groups larger than 80 and especially larger than 120 you need a very large roving microphone.

In the Mega Edition games each team has a leader. The leader is supplied with clear instructions of what to do next and then they guide their team with the presenter's help.
