Online Rock Paper Scissors: Play Instantly Against the Computer

Two people, one decision, no coin and no patience. The online rock paper scissors tool settles it in a tap — you pick rock, paper or scissors and the computer answers with a move it could not have known in advance.

What the tool does

It is a clean two-player showdown where one side is the computer. You choose a move from three big buttons; a short countdown runs; the computer reveals its throw at the same moment; and the winner is decided by the classic rules. A local scoreboard tracks your wins, draws and losses, and a short history keeps recent rounds.

Prefer a spinning wheel to pick for you? The random wheel can stand in as an impartial third party.

The rules, in one line each

• Rock beats scissors.
• Scissors beats paper.
• Paper beats rock.
• Same move on both sides is a draw.

The same logic appears in the rock paper scissors wheel guide if you want the wheel version.

Is the computer's move random?

Yes, and that is the whole point. The computer picks its move with your browser's cryptographically strong random generator, independently of your choice and of previous rounds. Nothing learns your habits, and no round influences the next — so a winning streak is just luck, not a pattern you can exploit.

When rock paper scissors is the right tool

• Deciding who goes first in a game or meeting.
• Settling a tie without debate.
• Picking who does the chore nobody wants.
• A quick classroom demo of fairness and probability.
• Breaking a deadlock between two equal options.

Tips for a smooth game

• Tap and wait for the countdown — the computer commits at the same instant, so neither side has an edge.
• Check the scoreboard to see the long-run split between wins, draws and losses.
• Reset when you want a clean slate; the history and score clear together.
• Keep it private — your moves and score never leave the browser.
