Everybody stands in a circle. One person (“It”) leaves the room. While “It” is out, everybody else decides who will be the “murderer” or “Assassin”. “It” is called back in, and stands in the center of the circle.
The “murderer” winks at people in the circle one by one. When someone is winked at, they have to fall down dramatically pretending to die.
“It” has to try and work out who the “murderer” is.
Once they guess (or if nobody but the murderer is left) the “murderer” then becomes “It” and the game starts over.
