CLUE BASED MURDER MYSTERY GAMES
At the event, your guests will come in character, as will you. The party is broken up into round and during each round the host will casually deliver clues. Each guest will receive a clue(s) and they will read to themselves. Most guest will receive a clue to reveal and one to conceal. The guests should then share their revealing clues at their leisure with whomever they choose. At the same time, they try to conceal their secret clue. Conceal means they try to avoid the subject or spin the topic - they CAN NOT LIE. This process is repeated for each round. The timing is up to you, but usually allow an hour per round.
LARGE GROUP (SCRIPTED) MYSTERIES
These games are lightly scripted designed to guide the cast but encourage improvisation. The cast will interact with all guests making it fun for all.
HOW TO ADAPT A CLUE BASED MYSTERY TO A LARGE GROUP SETTING.
A large group game requires a little more coordination, to ensure that all guests are included and they all become aware of the key clues. So when you convert a clue based game to a large group game you should assemble a cast and share with them the entire print kit, then you will need to stage out the night to ensure that the key clues are revealed to most of the guests. Once you got the details worked out, you might want to do a rehearsal to make sure the mystery unfolds correctly. You can add or change character clues as you need to fit your party.
Great. So now you have the mystery covered, now what about the other guests. The simplest solution is just invite the rest of the guests to come as th character of their choosing based on the theme of the party. Or you could create a character for them. (Warning: with a lot of guests this could be a lot of work).
Adding custom characters to your game is pretty easy. In fact often you can do it without knowing the mystery. Here are characters you add without knowing anything about the mystery:
An assistant character: You could create an assistant,twin, spouse or colleague for one of the characters. If you do this you are, in effect, turning one role into two. (You will need to make sure that the two people like working together). Just print two sets of clues for any character whom they are assisting and tell the two guests to work together.
Staff : Depending on the setting for the murder mystery, you might be able to add an extra character who is a servant, or a member of the staff or crew. You could give them some simple duties such as being in charge of serving the food and drinks. You should make sure that they have some clues, which will require a little creativity on your part.
