Rock Paper Scissors (also known as RPS, Roshambo, or Jan-Ken-Pon) is a classic hand game usually played between two people. Each player simultaneously forms one of three shapes with their hand: rock (a closed fist), paper (an open hand), or scissors (a fist with the index and middle fingers extended). The game has simple rules: rock crushes scissors, scissors cuts paper, and paper covers rock. Our online version lets you play this timeless game against a computer opponent with intelligent random selection, complete with statistics tracking and game history.

Frequently Asked Questions
The computer uses crypto.getRandomValues() — the browser's cryptographically-strong random number generator backed by the OS entropy pool — combined with rejection sampling so that each option (Rock, Paper, Scissors) has exactly a 1/3 probability with zero modulo bias. The computer has no memory or pattern; it cannot see your move; and the move stream is unpredictable even to a determined adversary. Math.random() is only used as a fallback in browsers that lack the Web Crypto API.
The rules are simple:
• Rock crushes Scissors (Rock wins)
• Scissors cuts Paper (Scissors wins)
• Paper covers Rock (Paper wins)
• If both players choose the same option, it's a draw
The game is won by choosing the option that beats your opponent's choice.
• Rock crushes Scissors (Rock wins)
• Scissors cuts Paper (Scissors wins)
• Paper covers Rock (Paper wins)
• If both players choose the same option, it's a draw
The game is won by choosing the option that beats your opponent's choice.
A win streak counts consecutive victories. Each time you win, your streak increases by 1. If you lose or draw, your current streak resets to 0. Your 'Best Win Streak' tracks the highest consecutive wins you've achieved in your game history.

Yes. Three properties guarantee fairness: (1) the move is sampled from crypto.getRandomValues, not from a predictable pseudo-random sequence; (2) we use rejection sampling to eliminate the small modulo bias that naive (uint32 % 3) would introduce; (3) the computer commits to its choice without ever reading your DOM input. The Nash equilibrium of RPS with random opponent is the uniform mixed strategy (1/3, 1/3, 1/3), so over many games no strategy can beat 33.33%.

Rock Paper Scissors has ancient origins, believed to have started in China during the Han Dynasty (around 206 BCE - 220 CE). The game spread to Japan where it became known as 'Jan-Ken' or 'Jan-Ken-Pon'. It gained worldwide popularity in the 20th century and is now played across all cultures as a simple decision-making tool and game.
In a truly random game of Rock Paper Scissors:
• Probability of winning: 33.33% (1 in 3)
• Probability of losing: 33.33% (1 in 3)
• Probability of drawing: 33.33% (1 in 3)
Over many games, your win percentage should approach 33.33% if both you and the computer are choosing randomly.
• Probability of winning: 33.33% (1 in 3)
• Probability of losing: 33.33% (1 in 3)
• Probability of drawing: 33.33% (1 in 3)
Over many games, your win percentage should approach 33.33% if both you and the computer are choosing randomly.
Yes — it is 100% free with unlimited games, no download, no sign-up and no ads-wall. The whole game runs in your browser using JavaScript, so once the page has loaded it keeps working offline; your stats and last-50-game history are saved locally in your browser. It plays the same on phone, tablet and desktop: tap the buttons on touch screens, or use the keyboard on a computer.
On a computer you can play entirely with the keyboard: press R for Rock, P for Paper, S for Scissors (the number keys 1, 2 and 3 also work). Press M at any time to toggle the sound effects on or off — your choice is remembered the next time you visit. There is also a Sound button next to Reset for the same toggle. On phones and tablets, just tap the Rock, Paper or Scissors buttons.
Against our computer you cannot beat 33.33% in the long run, because its moves are truly random with no pattern to read. Against humans, strategy matters: most people throw Rock first, tend to repeat the move that just won for them, and avoid the move they just lost with. So a common counter is to play the move that would have beaten the opponent's last winning throw, and to avoid being predictable yourself by mixing your throws as randomly as you can. Use this tool to test whether you can spot biases in your own rhythm.
