Is There a Winning Strategy?

Against a truly random opponent — like this computer — no strategy can give you an edge. Each of the three choices wins exactly one third of the time when your opponent is picking at random.

In real-life Rock Paper Scissors against human opponents, psychology and pattern recognition matter. Humans are not truly random — most people unconsciously repeat their last winning move or change after a loss, creating exploitable patterns.

Against this tool, the best you can do is enjoy the streaks and have fun. The computer picks each choice with exactly 33.3% probability every single round — no memory of previous rounds, no bias toward any option.
