There are 3 basic rules to the game of Rock Paper Scissors. You and one opponent both hold out a closed fist and count down, usually with a "Rock, Paper, Scissors" or "Rock, Paper, Scissors, Shoot." Clarify with your opponent beforehand to make sure you both are on the same page in terms of the countdown method. During this time, you both will think of Rock, Paper, or Scissors at random (ideally) and use the appropriate hand gesture to display which object you had chosen.
