Rock-paper -scissors - lizard - Spock is an expansion of the classical method of selection for playing rock-paper- scissors. It operates under the same basic principle , but includes two other additional weapons : the lizard (formed by the hand like a puppet 's mouth ) and Spock ( formed by greeting the Vulcans in Star Trek ) . This reduces the chances of a round end in a draw . The game was invented by Sam Kass and Karen Bryla like " Rock Paper Scissors Lizard Spock ." In this version, the possible outcomes are:

• Scissors cuts paper

• Paper covers rock

• Rock tips lizard

• Lizard Spock falls asleep

• Spock melts scissors

• Scissors holds lizard

• lizard eats paper

• Paper disproves spock

• Spock vaporizes rock

• Rock crushes scissors
