2017 Hand Game Rock-paper-scissors (Bato-bato Pick)

Rock-paper-scissors (also known as paper, rock, scissors or paper, scissors, stone) is a hand game usually played between two people, in which each player simultaneously forms one of three shapes with an outstretched hand. These shapes are "rock" (a simple fist), "paper" (a flat hand), and "scissors" (a fist with the index and middle fingers extended, forming a V).

A zero-sum game, it has only two possible outcomes other than a tie: one of the two players wins, and the other player loses.

A player who decides to play rock will beat another player who has chosen scissors ("rock crushes" or sometimes "blunts" scissors"), but will lose to one who has played paper ("paper covers rock"); a play of paper will lose to a play of scissors ("scissors cut paper").

If both players choose the same shape, the game is tied and is usually immediately replayed to break the tie. Originating from China and Japan, 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".

Rock-paper-scissors is often used as a choosing method in a way similar to coin flipping, drawing straws, or throwing dice. 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 3 or speak the name of the game
(e.g. "Rock! Paper! Scissors!" or "Ro Sham Bo!"),
each time either raising one hand in a fist
and swinging it down on the count or holding it behind.
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!" or "Bo!"), or a version
where they shake their hands three times before "throwing".

History-Origin source Wikipedia:

The first known mention of the game was in the book Wuzazu by the Chinese Ming-dynasty writer Xie Zhaozhi (fl. ca. 1600), who wrote that the game dated back to the time of the Chinese Han dynasty (206 BC – 220 AD). In the book, the game was called shoushiling. Li Rihua's book Note of Liuyanzhai also mentions this game, calling it shoushiling (t. 手勢令; s. 手势令), huozhitou (t. 豁指頭; s. 豁指头), or huoquan (豁拳).

Mushi-ken, the earliest Japanese sansukumi-kengame (1809). 
From left to right: slug (namekuji), frog (kawazu) and snake (hebi).

Throughout Japanese history, there are frequent references to sansukumi-ken, meaning ken (fist) games where "the three who are afraid of one another" (i.e. A beats B, B beats C, and C beats A). This type of game originated in China before being imported to Japan and subsequently also becoming popular among the Japanese.

The earliest Japanese sansukumi-ken game was known as mushi-ken (虫拳), which was imported directly from China. In mushi-ken the "frog" (represented by the thumb) is superseded by the "slug" (represented by the little finger), which, in turn, is superseded by the "snake" (represented by the index finger), which is superseded by the "frog". Although this game was imported from China the Japanese version differs in the animals represented. In adopting the game, the original Chinese characters for the poisonous centipede (蜈蜙) were apparently confused with the characters for the slug (蛞蝓). The most popular sansukumi-ken game in Japan was kitsune-ken (狐拳). In the game, a supernatural fox called a kitsune (狐) defeats the village head, the village head (庄屋) defeats the hunter, and the hunter (猟師) defeats the fox. Kitsune-ken, unlike mushi-ken or rock–paper–scissors, is played by making gestures with both hands.
