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 often used as a decision-making tool or a fun way to resolve disputes. The rules are straightforward: rock crushes scissors, scissors cuts paper, and paper covers rock. If both players choose the same shape, the game is a tie. This game is popular worldwide and is often played by children and adults alike for entertainment or to make quick choices.
