{{Blockquote|Upon consideration of the Motion&nbsp;– the latest in a series of [[Gordian knot]]s that the parties have been unable to untangle without enlisting the assistance of the federal courts&nbsp;– it is ORDERED that said Motion is DENIED. Instead, the Court will fashion a new form of alternative dispute resolution, to wit: at 4:00 P.M. on Friday, June 30, 2006, counsel shall convene at a neutral site agreeable to both parties. If counsel cannot agree on a neutral site, they shall meet on the front steps of the Sam M. Gibbons U.S. Courthouse, 801 North Florida Ave., Tampa, Florida 33602. Each lawyer shall be entitled to be accompanied by one paralegal who shall act as an attendant and witness. At that time and location, counsel shall engage in one (1) game of "rock, paper, scissors." The winner of this engagement shall be entitled to select the location for the 30(b)(6) deposition to be held somewhere in Hillsborough County during the period 11–12 July 2006.<ref>{{cite news| url=https://money.cnn.com/2006/06/07/magazines/fortune/judgerps_fortune/index.htm| publisher=CNN.com| access-date=2006-06-08| title=Order of the court: Avista Management vs. Wausau Underwriters Insurance Co| date=June 7, 2006| first=Gregory| last=Presnell| url-status=live| archive-url=https://web.archive.org/web/20150216120044/https://archive.fortune.com/2006/06/07/magazines/fortune/judgerps_fortune/index.htm| archive-date=2015-02-16}}</ref>}}

=== Auction house selection ===
[[Image:Les Grands Arbres au Jas de Bouffan, par Paul Cézanne, Yorck.jpg|thumb|[[Paul Cézanne|Cézanne]]'s ''Large Trees Under the Jas de Bouffan'' sold for $11,776,000 at [[Christie's]] in 2005.<ref name="CityReview">[http://www.thecityreview.com/s05cimp1.html Art/Auctions logo, Impressionist & Modern Art, Christie's, 7 pm, May 4, 2005, Sale 1514] {{Webarchive|url=https://web.archive.org/web/20080127185532/http://www.thecityreview.com/s05cimp1.html |date=January 27, 2008 }}.</ref>]]
In 2005, when Takashi Hashiyama, CEO of Japanese television equipment manufacturer [[Maspro Denkoh]], decided to auction off the collection of [[Impressionism|Impressionist]] paintings owned by his corporation, including works by [[Paul Cézanne]], [[Pablo Picasso]], and [[Vincent van Gogh]], he contacted two leading auction houses, [[Christie's]] International and [[Sotheby's]] 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 earn Hashiyama's approval. 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'', estimated to be worth between $12 million to $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'." Sotheby's said that they treated it as a [[game of chance]] and had no particular strategy for the game, but went with "paper".<ref>{{Cite news

=== FA Women's Super League match ===

=== Play by chimpanzees ===
In Japan, researchers have taught [[chimpanzee]]s to identify winning hands according to the rules of rock paper scissors.<ref>{{cite news|url=https://www.bbc.com/news/av/science-environment-40946194/chimps-can-play-rock-paper-scissors|title=Chimps can play rock-paper-scissors|work=BBC News|access-date=11 December 2017|archive-date=27 December 2017|archive-url=https://web.archive.org/web/20171227031016/http://www.bbc.com/news/av/science-environment-40946194/chimps-can-play-rock-paper-scissors|url-status=live}}</ref>

=== Game design ===

In many games, it is common for a group of possible choices to interact in a rock paper scissors style, where each selection is strong against a particular choice, but weak against another. Such mechanics can make a game somewhat self-balancing, prevent gameplay from being overwhelmed by a single [[dominant strategy]] and single dominant type of unit.<ref name="egenfeldt-nielsen">{{cite book|title=Understanding video games: the essential introduction|last=Egenfeldt-Nielsen|first=Simon|author2=Jonas Heide Smith|author3=Susana Pajares Tosca|publisher=Taylor & Francis|year=2008|isbn=978-0-415-97721-0|page=103}}</ref>

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. In ''[[Alex Kidd in Miracle World]]'', the player has to win games of rock paper scissors against each boss to proceed. Others use simple variants of rock paper scissors as subgames.

Many [[Nintendo]] role-playing games prominently feature a rock paper scissors gameplay element. In ''[[Pokémon (video game series)|Pokémon]]'', there is a rock paper scissors element in the type effectiveness system. For example, a Grass-typed Pokémon is weak to Fire, Fire is weak to Water, and Water is weak to Grass.<ref>{{cite web|url=https://www.vg247.com/2017/06/26/pokemon-go-type-chart-strength-weakness-effectiveness-type-pokemon-battles-explained/|title=Pokemon Go type chart - type strength, weakness and effectiveness for Pokemon battles explained - VG247|date=26 June 2017|access-date=4 March 2018|archive-date=4 March 2018|archive-url=https://web.archive.org/web/20180304233524/https://www.vg247.com/2017/06/26/pokemon-go-type-chart-strength-weakness-effectiveness-type-pokemon-battles-explained/|url-status=dead}}</ref> In the 3DS remake of ''[[Mario & Luigi: Superstar Saga]]'' and ''[[Mario & Luigi: Bowser's Inside Story]]'', the battles in the second mode use a “Power Triangle” system based on the game's three attack types: Melee, Ranged, and Flying. In the ''[[Fire Emblem]]'' series of strategy role-playing games, the Weapon Triangle and Trinity of Magic influence the hit and damage rates of weapon types based on whether they are at an advantage or a disadvantage in their respective rock paper scissors system. In the ''[[Super Smash Bros.]]'' series, the three basic actions used during battles are described in their respective rock paper scissors system: attack, defense, and grab.

The "Card-Jitsu" minigame in [[Club Penguin]] is a rock-paper-scissors game using cards that represent the three elements, Fire, Water and Snow. Fire beats snow, snow beats water, water beats fire.
