Rock-Paper-Scissors

«Rock-Paper-Scissors» is a hand game originating in China, usually played between two or three 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 finger and middle finger extended, forming a V). A simultaneous, zero-sum game, it has three possible outcomes: a draw, a loss, or a win.
