How to play
For as many players there are, cut that many pieces of paper. They don’t need to be big pieces.
On those pieces of paper write C for citizen on all but one. That one will have a M for Murderer.
Fold up all of the pieces of paper so that the letters are not visible.
Mix them up and then give a piece of paper to each person.
Decide on the form of murder. Typically just pass your hand over the front of the neck like a knife.
The lights are then turned off and the murderer can begin his reign of terror.
Everyone wonders in the dark trying to avoid the murderer until they come across a body. When discovered you turn on the lights.
Everyone that is still alive comes together to vote on who they think was the murderer. The person voted for dies and if they weren't the murderer then the lights are turned off and the game proceeds until the murderer is discovered.
You have to be quick to turn on the lights because the murderer can kill as many as they like until the lights are turned on.
