How to Use
Pick your hand: rock, paper, or scissors: and the bot picks one at the same time. Rock beats scissors, scissors beats paper, 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 best of 10 (first to 6 wins). 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 forever. Best-of-5 and best-of-10 modes end at a decisive match point with a short summary. Stats are persisted on your device between sessions.
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+ games to see the distribution smooth out. Best-of-10 mode is designed to reduce small-sample noise.
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 forever. Best of 5 ends when one side wins 3 games. Best of 10 ends when one side wins 6. The match tracker above the arena shows the current match score in each mode.
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 best-of-10 modes.
