Rock Paper Scissors Lizard Spock is an expanded version of the classic game Rock Paper Scissors. It was popularized by the TV show The Big Bang Theory and includes five choices: rock, paper, scissors, lizard, and Spock. Each choice can defeat two other choices while being defeated by the remaining two. In this game, rock crushes scissors, scissors cuts paper, paper covers rock, rock crushes lizard, lizard poisons Spock, Spock smashes scissors, scissors decapitates lizard, lizard eats paper, paper disproves Spock, and Spock vaporizes rock. This variation reduces the chances of a tie and adds more strategic options.
