About this tool

Play rock-paper-scissors against a computer opponent in your browser, whose move is chosen with cryptographic randomness, and keep score.

How does the computer pick?

Its move is drawn uniformly at random with crypto.getRandomValues, so it cannot predict or counter you.

Who wins a tie?

Matching moves are a draw and the win/loss scores stay the same.
