Priceonomics:

Rock Paper Scissors has serious players, organizing leagues, and sponsored tournaments that draw hundreds to compete for cash prizes. In 2006, Bud Light sponsored a tournament and offered a $50,000 cash prize.

While RPS advocates are eager to validate it as a serious pursuit, they also intend to have a good time. That said, if during a tournament you try to throw some sort of fourth move like dynamite that beats rock, paper, and scissors, you’ll be asked to leave.

Leave it to Canadians to come up with competitive “Rock, Paper, Scissors” and tie it into drinking beer.
