Jack en Poy

        is a hand game played by two people.

The players usually count aloud to four, 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.

 On the third count (saying,"Shoot!" or "Go!" "Scissors!" or   "Bo!"), 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 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." The gestures are    (in the 3 gesture version):

• Rock, represented by a clenched fist.
• Scissors, represented by two fingers extended and separated, sometimes coming together
• Paper, represented by an open hand, with the fingers extended and touching, in order to represent a sheet of paper (horizontal).

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

• Rock blunts or breaks scissors: 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.
