Rock Paper Scissors

Rock paper scissors is a game in which opposing players simultaneously choose one of three hand gestures. It originated in china, possibly during the han dynasty, around two thousand years ago. The game spread to japan in the seventeenth century, where new tripartite versions emerged. In malasia, for instance, bird drinks water, water sinks stone, and stone hits bird. An indanesian version features an elephant which crushes a person who crushes an earwig.
