The Paper Scissors Stone Club was founded in England in 1842 and provided an environment free from the long arm of the law where enthusiasts could come together and play for honor, according to the World RPS (Rock Paper Scissors) Society Web page (www.worldrps.com).
In 1918, the name was changed to World RPS Club to reflect the growing international representation and its headquarters moved from London to Toronto. In 1925 its membership topped 10,000.
The world championships have been held since 2002.
