Rock Paper Scissors is the classic non transitive game of chance,or skill if you know a bit of psychology. But if you want to remove the psychological element AND introduce some extra complexity, you need the Rock Paper Scissors Lizard Spock dice. As I'm sure you know:
Scissors cuts Paper
Paper covers Rock
Rock crushes Lizard
Lizard poisons Spock
Spock smashes Scissors
Scissors decapitates Lizard
Lizard eats Paper
Paper disproves Spock
Spock vaporizes Rock
(and as it always has) Rock crushes Scissors
These are a good compliment to our other set of 5 non transitive dice, the Grime Dice.
