Customer Testimonial
I wanted to do something special for my 30th birthday. After researching online I found your site, booked a host and selected the Hollywood game. The host made the night run very easily and it was a great theme for guests to get into. The instructions were very clear and the game ran for two to three hours. The guests loved it and I would definitely do one again.

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.
What food works best for a murder mystery party?
Finger foods or buffets work best, as they allow guests to eat while interacting and solving the mystery. If you want a full meal we strongly recommend you play the game before or after dinner.
