Players are either civilians or murderers. Sit in a way where everyone can see everyone.
If there are multiple murderers: At the start, all players close their eyes for 5 seconds. Only murderers open their eyes to see who their fellow murderers are.
Murderers eliminate civilians by winking at them. When winked at, the civilian must make a gesture signaling they are eliminated.
If someone has suspicion, they can raise their hand and call for a vote.
On a count of 3, everyone points at who they suspect is a murderer.
If a murderer is voted out and it's the last one, civilians win!
If a civilian is voted out, the game continues.
Murderers win when there are as many or more murderers than civilians remaining.
