I DON’T KNOW WHICH ONE TO SHOOT: the game of clones, a gun, and asking questions only you would know the answer to
One player holds “the gun.” Everyone else plays identical people. The player with the gun asks every other player questions “only the original would know the answer to.”
Gameplay continues until the questioner decides they know who the original is. Game is lost if they actually shoot anyone, ’cause what the hell, that’s not a way to solve problems.
