Paper Scissors Stone

The secret to winning at rock, paper, scissors

A simultaneous , zero-sum game , it has only two possible outcomes: A player who decides to play rock will beat another player who has chosen scissors "rock crushes scissors" or sometimes "blunts scissors" [1] , but will lose to one who has played paper "paper covers rock" ; a play of paper will lose to a play of scissors "scissors cuts paper". If both players choose the same shape, the game is tied and is usually immediately replayed to break the tie. The type of game originated in China and spread with increased contact with East Asia, while developing different variants in signs over time.

Other names for the game in the English-speaking world include roshambo and other orderings of the three items, with "rock" sometimes being called "stone".

Poll: ‘Paper, Scissors, Stone’ or ‘Rock, Paper, Scissors’?

Rock—paper—scissors is often used as a fair choosing method between two people, similar to coin flipping , drawing straws , or throwing dice in order to settle a dispute or make an unbiased group decision. Unlike truly random selection methods, however, rock—paper—scissors can be played with a degree of skill by recognizing and exploiting non-random behavior in opponents.

The players usually count aloud to three, or speak the name of the game e. They then "throw" by extending it towards their opponent. Variations include a version where players use only three counts before throwing their gesture thus throwing on the count of "Scissors!

A New York Times article of on the Tokyo rush hour describes the rules of the game for the benefit of American readers, suggesting it was not at that time widely known in the U. It is impossible to gain an advantage over a truly random opponent. However, by exploiting the weaknesses of non-random opponents, it is possible to gain a significant advantage.

In tournament play, some players employ tactics to confuse or trick the other player into making an illegal move, resulting in a loss. One such tactic is to shout the name of one move before throwing another, in order to misdirect and confuse their opponent. During tournaments, players often prepare their sequence of three gestures prior to the tournament's commencement. The "rock" move, in particular, is notable in that it is typically represented by a closed fist—often identical to the fist made by players during the initial countdown.

If a player is attempting to beat their opponent based on quickly reading their hand gesture as the players are making their moves, it is possible to determine if the opponent is about to throw "rock" based on their lack of hand movement, as both "scissors" and "paper" require the player to reposition their hand. This can likewise be used to deceive an anticipating opponent by keeping one's fist closed until the last possible second, leading them to believe that you are about to throw "rock".

As a consequence of rock—paper—scissors programming contests, many strong algorithms have emerged. The optimal strategy or metastrategy is chosen based on past performance. The main strategies it employs are history matching, frequency analysis, and random guessing. Its strongest strategy, history matching, searches for a sequence in the past that matches the last few moves in order to predict the next move of the algorithm.

In frequency analysis, the program simply identifies the most frequently played move. The random guess is a fallback method that is used to prevent a devastating loss in the event that the other strategies fail.
