Before the game starts, ask someone to be the ‘the killer’ and ask them to keep their identity a secret. Explain to participants that one person among the group is the killer, and they can kill people by winking at them. Everyone then walks around the room in different directions, keeping eye contact with everyone they pass. If the killer winks at you, you have to play dead (by crouching or sitting on the floor). Everyone has to try and guess the killer by raising their hand up. If the killer is revealed, you can choose a new one and the game continues.
