Learn to play Sheldon's Jo Ken Po!

Rock, Paper, Scissors, Lizard and Spock is an expansion of the classic rock-paper-scissors game. It works on the same basic principle, but includes two additional weapons: the lizard and the Spock.

But clama, it was not Sheldon Cooper who invented this variant of the traditional Jokenpo.
This version was invented by Sam Kass, a software developer from New Jersey, and his friend Karen Bryla.

The rules are:

Scissors cut paper; copper stone paper;
stone crushes lizard; lizard poisons Spock;
Spock breaks scissors; scissors decapitates lizard;
lizard eats paper; paper contests Spock;
Spock vaporizes stone; stone crushes scissors!

Simple, isn't it?
