The history of Rock Paper Scissors

Rock Paper Scissors is one of the oldest hand games still played today. Its story runs from Han-dynasty China through Japanese janken to modern world championships - about 2,000 years of settling arguments with three hand shapes.

Ancient origins in China

The earliest known ancestor of the game is shoushiling, a Chinese hand game recorded during the Han dynasty (206 BC - 220 AD). Like the modern game, it used simultaneous hand signs in a cycle where each sign defeated one other and lost to another - the core idea that still defines Rock Paper Scissors.

Japanese ken games and janken

Hand games of this family, called ken games, flourished in Japan from the 17th century onward. An early favourite was mushi-ken, played with a frog, a slug, and a snake. The version the world knows today - janken, with rock (guu), scissors (choki), and paper (paa) - took shape in the 19th century. Rounds begin with the call 'jan-ken-pon', and janken remains an everyday decision-making tool in Japan.

Spreading to the West

Western writers began describing the Japanese game in the early 20th century, and through the mid-1900s it spread across Europe and North America under names like roshambo, becoming the playground standard for settling disputes. The rules stayed exactly the same: three shapes, one simple cycle.

Championships and the modern game

In the 2000s the World Rock Paper Scissors Society staged televised international championships in Toronto, and organized leagues, bar tournaments, and charity events continue worldwide. Competitive players treat the game as psychology rather than luck - reading habits and baiting throws, the same skills covered in our winning strategy guide and quantified in the odds and probability breakdown.
