Lizard-Spock is a variation of the classic hand game Rock-Paper-Scissors. It was popularized by the television show The Big Bang Theory. In this game, players can choose from five options: Rock, Paper, Scissors, Lizard, and Spock. Each option can defeat two other options while being defeated by two others, creating a more complex and balanced game. The rules are simple: Rock crushes Scissors, Scissors cuts Paper, Paper covers Rock, Lizard poisons Spock, Spock smashes Scissors, Scissors decapitates Lizard, Lizard eats Paper, and Paper disproves Spock. This expanded version adds more variety and strategy to the traditional game.
