Explanation

The Rock, Paper, Scissors, Lizard, Spock game is a variant of Rock, Paper, Scissors game invented by Sam Kass and Karen Bryla with Spock signified using the Star Trek Vulcan salute, and lizard sometimes shown in diagrams by forming the hand into a sock-puppet-like mouth ¹. The following diagram from Wikimedia² explains how each game is resolved. See the output of explain_the_game() below for the logic behind the diagram.
