How to Use
Pick rock, paper, or scissors, and the bot will make its choice at the same time. Rock beats scissors, scissors beats paper, and paper beats rock. Ties are shown but do not count as a win or loss.
Three modes: endless for casual play, best of 5 (first to 3 wins), and first to 6 for a longer match. Switch modes at any time using the selector above the arena. Changing modes resets the current match but your lifetime stats are preserved.
Wins, losses, ties, current streak, and best streak are saved on your device. The bot plays uniformly at random using the Web Crypto API: it does not learn your pattern or adapt. Over many games its choices converge to 33.3% each, which you can verify by watching the tallies over time.
About This Tool
Rock Paper Scissors is the classic hand game played against a cryptographically random bot. Pick rock, paper, or scissors; the bot reveals its choice; the winner is announced. Counters track wins, losses, ties, current streak, and best streak.
Endless mode runs until you stop. Best-of-5 and first-to-6 modes end at a decisive match point with a short summary. Stats are persisted on your device between sessions.
Privacy Note
Game state stays on your device. Bot choices come from crypto.getRandomValues in your browser.
Limits
The bot is uniformly random. It does not adapt to your pattern. For a human-vs-human match, share the URL and take turns clicking.
Random tools are most helpful when the rules are clear before the result is generated. Decide what the input means, whether duplicates are allowed, and whether the first result should be final. Clear rules make the result easier to trust and explain.
For casual choices, games, classroom activities, examples, and creative prompts, a browser-based tool is usually enough. For regulated contests, high-value selections, safety decisions, legal records, or professional advice, use a process designed for that responsibility.

Frequently Asked Questions
Yes. Every bot pick uses crypto.getRandomValues for uniform randomness. Over many rounds its choices converge to 33.3% rock, 33.3% paper, 33.3% scissors. It does not adapt to your pattern.
Short-run streaks are expected from uniform randomness. In 10 games, the bot will sometimes win 7 purely by chance. Play 50 or more games to see the distribution smooth out. The first-to-6 mode provides a longer match than best of 5.
Yes. Wins, losses, ties, current streak, and best streak are saved in your browser's localStorage. They persist across page refreshes and visits. Use "Reset stats" to start fresh.
Endless runs until you stop. Best of 5 ends when one side wins 3 games. First to 6 ends when one side reaches 6 wins. The match tracker above the arena shows the current score.
Not directly: the bot is your opponent. For a two-person match, share the URL, take turns picking without peeking, and compare results. Each pick is private to the local browser.
A tie shows "both picked X" and your current streak is preserved (not broken, not incremented). Ties do not advance the match score in best-of-5 or first-to-6 modes.
