Rock paper scissors is a hand game played by two or more people. The players usually count aloud to four or speak the name of the game (e.g. "Rock Paper Scissors!" ), 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. This program is written using the C# programming language.
