As its name implies, Rock, Paper, Scissors, like a really limited periodic table, involves three elements. Each one of these elements has a winning, losing, and tying combination against an opponent. On paper, this sounds like there is only ever a 1/3 chance of winning with each throw. But introduce a little human psychology into your game, and you have an edge and a game plan for winning. Eating a good breakfast before a big match or taking some healthy trim might even be a way to beat your opponent!
