Rock Paper Scissor

Rock Paper Scissor 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 closed fist), "paper" (a flat hand), and "scissors" (a fist with the index and middle fingers extended, forming a V). "Scissors" is identical to the two-fingered V sign (aka "victory" or "peace sign") except that it is pointed horizontally instead of being held upright in the air. A simultaneous, zero-sum game, it has only two possible outcomes other than a tie: one of the two players wins, and the other player loses.
