Rock Paper Scissors is a simple 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). The game is decided based on the following rules: rock crushes scissors, scissors cut paper, and paper covers rock. If both players choose the same shape, the game is a tie, and they usually play again.
