Lizard Spock is a variation of the classic game Rock, Paper, Scissors, created by comedian Sam Kass and popularized by the television show The Big Bang Theory. In this version, two additional choices are introduced: Lizard and Spock. The game is played in the same way as the original, with players simultaneously showing one of the five options. In Lizard Spock, the rules dictate that Scissors cuts Paper, Paper covers Rock, Rock crushes Lizard, Lizard poisons Spock, Spock smashes Scissors, Scissors decapitates Lizard, and Lizard eats Paper. This expanded version adds complexity and fun to the traditional game.
