I invented this game (with Karen Bryla) because it seems like when you know someone well enough, 75-80% of any Rock-Paper-Scissors games you play with that person end up in a tie. Well, here is a slight variation that reduces that probability. (Note that for those of you who like to swing your fist back and forth and say, "Rock, Paper, Scissors, GO!", might want to continue to do that, replacing "Rock" with "One," "Paper" with "Two," and "Scissors" with "Three.") This version is also nice because it satisfies the Law of Fives.

• Paper covers Rock
• Rock crushes Lizard
• Lizard poisons Spock
• Spock smashes Scissors
• Scissors decapitates Lizard
• Lizard eats Paper
• Paper disproves Spock
• Spock vaporises Rock
• Rock crushes Scissors

• Scissors decapitates Lizard and cuts Paper, but can be smashed by Spock and crushed by Rock
• Paper disproves Spock and covers Rock, but can be eaten by Lizard and cut by Scissors
• Rock crushes both Lizard and Scissors, but can be vaporised by Spock and covered by Paper
• Lizard eats paper and poisons Spock, but is decapitated by scissors and crushed by rock
• Spock vaporises Rock and smashes Scissors, but is poisoned by Lizard, and disproven by Paper
