RockPaperScissor

Rock-paper-scissors or Scissor-Paper-Rock, is a zero-sum hand game usually played between two people, in which each player simultaneously forms one of three shapes with an outstretched hand.The game 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.
