Rock-paper-scissors is a hand game

selection methods, rock-paper-scissors can be played with a degree of skill, especially if the game extends over many sessions with the same players; it is often possible to recognize and exploit the non-random behavior of an opponent.

Game play

The players count aloud to three, or speak the name of the game (e.g. "Rock Paper Scissors!" or "Ro! Cham! Beau!"), each time raising one hand in a fist and swinging it down on the count. After the third count (saying, "Scissors!" or "Beau!"), the players change their hands into one of three gestures, which they then "throw" by extending it towards their opponent. Variations include a version where players use a fourth count—"Shoot!"—before throwing their gesture, or a version where they only shake their hands twice before "throwing." The gestures are:

Rock, represented by a clenched fist.
Scissors, represented by two fingers extended and separated.
Paper, represented by an open hand, with the fingers connected (horizontal).

The objective is to select a gesture which defeats that of the opponent. Gestures are resolved as follows:

Rock blunts or breaks scissors: that is, rock defeats scissors.
Scissors cut paper: scissors defeats paper.
Paper covers, sands or captures rock: paper defeats rock.

If both players choose the same gesture, the game is tied and the players throw again.

History

According to the Chinese Ming Dynasty

The Ming Dynasty, also Empire of the Great Ming, was the ruling dynasty of China from 1368 to 1644, following the collapse of the Mongol-led Yuan Dynasty.

Variations

There is a simpler variation of the game, where instead of three possibilities, the game is just played with two possibilities.
This version is called matching pennies

, the two strategy equivalent to rock-paper-scissors.

Players have developed numerous cultural and personal variations on the game, from simply playing the same game with different objects, to expanding into more weapons and rules.

Rock-paper-scissors is frequently played in a "best two out of three" match, and in many cases psychs-out, shouting, and trick gestures are performed to confuse or trick the other player into throwing an illegal toss resulting in a loss. Some players prefer to shout the name of a throw they do not intend to throw in order to misdirect and confuse their opponent. It generally applies that what is thrown is what is officially counted in the match. For instance, yelling Scissors or Paper, and actually throwing Rock. The rock is what is judged and tallied. During tournaments, players often prepare their sequence of three gestures prior to the tournament's commencement.

Additional weapons

With an odd number of choices, each beats half the weapons and loses to half the weapons. No even number of weapons can be made balanced, unless some pairs of weapons result in a draw; there will always be some weapons superior to others.

An example of an unbalanced four-weapon game adds "dynamite

Dynamite

Dynamite is an explosive material based on nitroglycerin, initially using diatomaceous earth , or another absorbent substance such as powdered shells, clay, sawdust, or wood pulp. Dynamites using organic materials such as sawdust are less stable and such use has been generally discontinued...

" as a trump. Dynamite, expressed as the extended index finger or thumb, always defeats rock, and is defeated by scissors. Using dynamite generally implies that dynamite burns paper, but some claim that paper would smother the fuse. The fourth option of dynamite changes each gesture's odds of winning. For instance, scissors' odds improve from 33% to 50% while rock's odds decrease from 33% to 25%. Dynamite can be used to cheat by quickly raising or lowering the thumb on the downstroke once the opponent's play is recognized. Organized rock-paper-scissors contests never use dynamite.
Similarly, the French game "pierre, papier, ciseaux, puits" (stone, paper, scissors, well) is unbalanced; both the rock and scissors fall in the well and lose to it, while paper covers both rock and well. This means two "weapons", well and paper, can defeat two moves, while the last two weapons can only defeat one of the other three choices.
One popular five-weapon expansion, invented by Sam Kass and Karen Bryla, adds "Spock

, "The Lizard-Spock Expansion," in 2008.
As long as the number of moves is an odd number and that each move defeats exactly half of the other moves while being defeated by the other half, any combination of moves will function as a game. For example, 7, 9, 11, 15, 25 and 101 weapon versions exist Adding new gestures has the effect of reducing the odds of a tie, while increasing the complexity of the game. The probability of a tie in a balanced, odd-weapon game can be calculated based on the number of weapons n as 1/n, so the probability of a tie is 1/3 in RPS, 1/5 in RPSLS and 1/101 in RPS101.
It is possible to design balanced RPS games with an even number of weapons; unfortunately, this requires the introduction of ties. For instance, dynamite could be introduced such that dynamite defeats rock and paper defeats dynamite while rock and paper tie, as do scissors and dynamite. The probability of a tie in a balanced, even-weapon RPS game with n weapons (assuming each weapon ties with itself and only one other weapon, while defeating half of the remaining weapons and being beaten by the other half) can be calculated as 2/n, which essentially doubles the probability of a tie in comparison with odd-weapon RPS games.

Holdings, seeking their proposals on how they would bring the collection to the market as well as how they would maximize the profits from the sale. Both firms made elaborate proposals, but neither was persuasive enough to get Hashiyama’s business. Unwilling to split up the collection into separate auctions, Hashiyama asked the firms to decide between themselves who would hold the auction, which included Cézanne's "Large Trees Under the Jas de Bouffan", worth $12–16 million.

The houses were unable to reach a decision. Hashiyama told the two firms to play rock-paper-scissors to decide who would get the rights to the auction, explaining that "it probably looks strange to others, but I believe this is the best way to decide between two things which are equally good".

The auction houses had a weekend to come up with a choice of move. Christie's went to the 11-year-old twin daughters of the international director of Christie's Impressionist and Modern Art Department Nicholas Maclean, who suggested "scissors" because "Everybody expects you to choose 'rock'."

video games, it is common for a group of possible weapons or unit types to interact in a rock-paper-scissors style, where each selection is strong against a particular choice, but weak against another, emulating the cycles in real world warfare (such as cavalry being strong against archers, archers being strong against pikemen, and pikemen being strong against cavalry). Such game mechanics can make a game somewhat self-balancing, and prevent gameplay from being overwhelmed by a single dominant strategy.

Many card-based video games in Japan use the rock-paper-scissors system as their core fighting system, with the winner of each round being able to carry out their designated attack. Other games use simple variants of rock-paper-scissors as subgames.

Kirkup, Jr. further demonstrated that the colicins were active as E. coli compete with each other in the intestines of mice, and that the rock-paper-scissors dynamics allowed for the continued competition among strains: antibiotic-producers defeat antibiotic-sensitives; antibiotic-resisters multiply and withstand and out-compete the antibiotic-producers, letting antibiotic-sensitives multiply and out-compete others; until antibiotic-producers multiply again.

s that play rock-paper-scissors.

Algorithms

As a consequence of rock-paper-scissors programming contests, many strong algorithms have emerged. For example, Iocaine Powder, which won the First International RoShamBo Programming Competition in 1999, uses a heuristically designed compilation of strategies. For each strategy it employs, it also has six metastrategies which defeat second-guessing, triple-guessing, as well as second-guessing the opponent, and so on. 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. More than ten years later, the top performing strategies on an ongoing rock-paper-scissors programming competition similarly use metastrategies. However, there have been some innovations, such as using multiple history matching schemes that each match a different aspect of the history - for example, the opponent's moves, the program's own moves, or a combination of both. There have also been other algorithms based on Markov chain

Red Bull Roshambull World Online Series

The Red Bull Roshambull is a Recognized Unofficial event by the World RPS which takes place over the Facebook application "Red Bull Roshambull". Although originally an unrecognized event, in January 2011 it was given a Official Recognized event status due to the number of people who regularly take part in the World Championships and other recognized leagues starting to compete. However the event is still seen as a non-ranking event and any awards or titles given in the tournament are not officially recognized outside the event.

The World Series is a multiple-tournament contest in which a player's performance in each separate tournament is scored, and after a number of tournaments within the event have taken place, a triple-elimination playoff takes place to decide a overall championship.
Over the last few seasons, extra events have been added to the series, the most popular of them being the "Hidden Stars" (a tournament for novice players on the application who may not know about the event being given a chance to compete without any regulars taking part) and the World Series Blitz (where all the events take place over one day rather than once a week like in the main event).

The key feature of this event is the number of players who are not known as people who play in real-life tournaments who show a lot of ambition to try to compete with those who play in the most recognized events on a regular basis.
