Rock-Paper-Scissors is a simple hand game usually played between two people. Each player simultaneously forms one of three shapes with their hand: rock, paper, or scissors. The game is based on a set of rules where rock crushes scissors, scissors cuts paper, and paper covers rock. The game is often used as a decision-making tool or a way to resolve disputes. It is quick to play and requires no special equipment, making it popular in various cultures around the world. Players typically play multiple rounds to determine a winner.
