Rock Paper Scissors is a simultaneous-choice game. No legal throw has an automatic advantage, and no pattern guarantees the next result.
Completed History Is Not Mind Reading
Players can form habits, so completed rounds may help you form a hypothesis. Treat that hypothesis as uncertain: a short sample can be misleading, and an opponent can change approach at any time.
What Fair Browser Practice Means
In WRPSA browser practice, the server selects the opponent throw from completed history only. It seals that throw with a SHA-256 commitment before accepting your input, then reveals the throw and salt after the round so the browser can verify the commitment and result.
The opponent does not receive your current hidden throw before its own throw is committed. If a commitment, reveal, score, or response is invalid, the browser does not display a round result.
Practice Without False Certainty
Mix your choices, notice your own repeated habits, and review only completed results. A useful practice session can sharpen attention and decision-making, but it cannot promise a guaranteed edge.
