How to play

In case you didn’t learn this on the playground ages ago:

Two players each present a fist, then move their fists up and down in a hammering motion. The third* time they bring their hands down, each player displays (“throws”) one of three positions:

(1) Rock

(2) Paper

(3) Scissors

The winner is determined by this formula:

• Rock breaks scissors.

• Scissors cut paper.

• Paper covers rock.

If players show the same hand position, they tie and replay the round.

Winning two out of three rounds usually constitutes a bout. A match may be several bouts.

*In some events, the game position is taken on the fourth move, so it’s important to agree on rules beforehand.
