The rules, and a bit of strategy
Rock crushes scissors, scissors cut paper, and paper covers rock. Against a truly random opponent
there is no winning strategy — it evens out over time — which makes rock paper scissors a perfectly
fair way to settle a small decision, pick who goes first, or just pass a couple of minutes. Against
human opponents, people are famously not random, which is where reading patterns comes in.
Frequently asked questions
How does the computer choose?
The computer picks rock, paper, or scissors completely at random, with an equal chance each time, using your browser's random number generator. It cannot see your choice, so every round is fair.
What beats what?
Rock beats scissors, scissors beats paper, and paper beats rock. If you both pick the same, it is a tie.
Is there a way to always win?
No. Because the computer plays at random, no strategy beats it over the long run — your expected result is roughly a third wins, a third losses, and a third ties.
Does it keep score?
Yes. Your wins, losses, and ties are tallied on screen for the session. Reloading the page starts a fresh scoreboard.
