About Rock Paper Scissors

Rock Paper Scissors transcends its elementary surface to reveal deep psychological game theory: in theory it's a pure 50/50 random game, but in practice human players exhibit predictable biases that skilled opponents can exploit. People tend to repeat successful choices, switch after a loss, and often telegraph their next move through hesitation and body language — patterns that experienced RPS players study as seriously as poker players study tells. World RPS championships exist precisely because competitive play at high levels becomes an exercise in behavioral prediction and recursive meta-thinking: 'what will they choose knowing I'm thinking about what they'll choose.'
