Rochambeau is a popular hand game often known as "rock-paper-scissors." Players simultaneously form one of three shapes with their hands: a rock (a fist), paper (an open hand), or scissors (a fist with the index and middle fingers extended). The game is played to determine a winner based on the rules: rock crushes scissors, scissors cuts paper, and paper covers rock. This simple game is often used to make decisions or resolve disputes in a fun and fair manner. It is played worldwide and has various names and variations, but the core concept remains the same across cultures.
