Rock-paper-scissors is a hand game usually played between two people. This game is great when played as a tag game.
On the count of 3 each player forms one of three shapes with an outstretched hand. These shapes are "rock" (a simple fist), "paper" (a flat hand), and "scissors" (a fist with the index and middle fingers extended, forming a V).
A player who decides to play rock will beat another player who has chosen scissors ("rock crushes"- scissors"), but will lose to one who has played paper ("paper covers rock"); a play of paper will lose to a play of scissors ("scissors cut paper").
If both players choose the same shape, the game is tied and you play again imnmmediately.
To turn this into a tag game, the 'loser' must chase the 'winner' and tag them and then the game is repeated.
