Rock-paper-scissors is a hand game usually played by two people, where players simultaneously form one of three shapes with an outstretched hand. The "rock" beats scissors, the "scissors" beat paper and the "paper" beats rock; if both players throw the same shape, the game is tied. Other names for the game in the English-speaking world include roshambo, Paper-Scissors-Stone, ick-ack-ock and other orderings of the three items.
