FAQ
How does a murder mystery party work?
A murder mystery party follows a structured storyline with a beginning, middle, and conclusion. The event starts with the crime being introduced, followed by a period of investigation where guests gather clues, question each other, and uncover secrets.

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.
