SA STA Clans: Rock, Paper, and Scissors

Since June 3, 2008

Rock-paper-scissors (also known as jan-ken-pon, rochambeau, ching-chang-wulla, and many derived terms, is a popular two-person hand game.

The game is often used as a selection method in a similar way to coin flipping or drawing straws to randomly select a person for some purpose. However, unlike truly random selections, it can be played with skill if the game extends over many sessions, as a player can often recognize and exploit the non-random behavior of an opponent.

Sportspeople often use the game (both officially and unofficially, in place of a coin toss) to decide on opening plays. Similarly, uncertain calls, or even the whole game in case of rain, may be so decided. It is also often used as a method for creating appropriately non-biased random results in live action role-playing games, as it requires no equipment. It is also used in some online gambling sites as a form of novelty betting.
