Frequently Asked Questions
How does the computer choose its move?
The computer picks from Rock, Paper, or Scissors using Math.random() — each move has exactly 1/3 probability. There is no pattern, prediction, or adaptation based on your history. You cannot gain an advantage by playing a sequence; every round is independent.
Can I play Best of 5?
Yes. Select "Best 5" in the mode selector in the header. The series continues until one side wins 3 rounds. Progress dots show the current score within the series. A banner announces the series winner.
Are there keyboard shortcuts?
Yes. Press R to throw Rock, P to throw Paper, and S to throw Scissors — all without touching the mouse. This makes the game faster and more reactive. Shortcuts only activate when you are in the move selection phase, not while the result is being shown.
