How to Play Rock Paper Scissors
Rock Paper Scissors is decided in a single simultaneous throw. Learn the three shapes and the winning triangle, throw on “shoot”, and win the majority of rounds in a best-of match.
Play Rock Paper ScissorsThe objective
Win more rounds than the computer
Each round, you and the computer secretly pick rock, paper, or scissors and reveal at the same time. Rock beats scissors, scissors beats paper, and paper beats rock. The player with the winning shape takes the round; matching shapes are a draw and replay.
A match is best of 3, 5, or 7. The first side to win the majority — two, three, or four rounds — wins the match. Because no shape is stronger than another, your only edge is anticipating the computer while keeping your own choices unpredictable.
The game is free, runs in the browser, and needs no account. Open the board to play; use this guide for the rules, the two opponent styles, and the habits that win more rounds.
The three throws
Rock beats scissors, scissors beats paper, paper beats rock
Rock is a closed fist, paper is a flat open hand, and scissors is two fingers extended. Each shape beats exactly one of the other two and loses to the third, so the three form a closed loop with no dominant option.
When both players throw the same shape, the round is a tie. It is recorded in your stats but does not change the match score — the round is simply replayed until it is decisive.
Controls
Tap or use the keyboard
Every method throws the same shapes. Pick whichever fits the device in your hand.
Touch
Tap a throw
Three large buttons for rock, paper, and scissors sit within thumb reach at the bottom of the screen. Tap one to lock it in for the round; tap again after the reveal to throw the next round.

R / P / S keys
Press R for rock, P for paper, or S for scissors. The number keys 1, 2, and 3 map to the same three throws in that order for players who prefer the left hand.

Space, N, and M
Space or Enter starts a match from the setup screen and plays again after a match ends. N abandons the current match and returns to setup. M mutes and unmutes the synthesized sound. Every on-screen control also has a visible focus ring.
The loop
Four steps you repeat every match
Setup once, then throw, read the result, and go again until the match is decided.

Know the three throws
Every round is one simultaneous choice between three shapes. Rock is a closed fist, paper is a flat open hand, and scissors is two fingers extended. There is no fourth option and no way to pass.

Learn what beats what
Rock crushes scissors, scissors cuts paper, and paper covers rock. Each throw beats exactly one of the others and loses to the third, so the game is a perfectly balanced triangle. Two identical throws tie and the round is replayed.

Throw on “shoot”
Pick your shape during the “Rock, Paper, Scissors, Shoot” count. Here you tap or press a key; the computer commits at the same instant, so you are never reacting to its move. The result is revealed the moment both hands are in.
- 4
Win the match
A match is best of 3, 5, or 7. The first player to take the majority of rounds — two, three, or four — wins the match. Ties do not count toward either total. Start a new match instantly without reloading the page.
Rules & scoring
Every rule that decides a match
The objective
Win more rounds than the computer before the match runs out. A round is won by throwing the shape that beats the opponent’s shape; a match is won by reaching the majority of rounds in a best-of-3, best-of-5, or best-of-7.
The winning triangle
Rock beats scissors, scissors beats paper, paper beats rock. Each shape wins against one and loses against one, so no throw is stronger than another on paper — the edge only comes from anticipating the opponent.
Ties
If both players throw the same shape the round is a draw. Draws are recorded in your stats but do not move the match score; the round is simply replayed until it is decisive.
Match formats
Best of 3 is first to 2 rounds, best of 5 is first to 3, best of 7 is first to 4. Choose the format on the setup screen before a match; it cannot change mid-match.
Simultaneous commitment
Both hands are thrown at once. The computer chooses in the same instant you lock in, and its choice for the round is fixed before yours is revealed, so there is no reaction advantage on either side.
Opponents
Fair Play versus Mind Reader
Choose an opponent on the setup screen. Stats are kept separately for each.
- 01 · A truly random opponent
Fair Play
The computer throws each shape with equal probability and never looks at your history. Over many rounds the contest sits at one third win, one third loss, one third tie, exactly as the maths predicts. This is the honest coin-flip version — good for a quick game or settling a decision.
- 02 · An AI that learns your habits
Mind Reader
This opponent keeps a running model of how often you throw each shape and which throw usually follows which, plus the common human tendency to play the shape that would have beaten its last move. It predicts your next throw and plays the counter, with a little deliberate noise so the game never feels scripted. Play unpredictably and it drifts back toward even.
Common mistakes
Why readable players lose
Repeating a winning throw
Throwing rock again because it just won is the most readable move there is. A watching opponent will play paper the next round. Vary your follow-up even when the last throw worked.
The predictable switch after a loss
Losing with rock and immediately jumping to paper is a reflex nearly everyone shares. If your opponent expects the switch, they throw scissors. Decide your next throw before you know you have lost.
Opening with rock
First-throw rock is the single most common opening among casual players, especially men. Leading with paper is a small but real edge against a stranger — and a trap if they have read the same advice.
Trying to out-think forever
Endless second-guessing collapses back into a pattern of its own. Sometimes the strongest play against a strong opponent is to genuinely randomise and accept the even odds.
- Do not fall into a fixed cycle. Rock then paper then scissors, repeated, is the easiest pattern in the game to punish.
- Watch your own bias. Under pressure most people throw rock first and lean away from scissors — assume a sharp opponent knows that too.
- After you lose a round, players tend to switch to the throw that just beat them. After a win, they tend to repeat. Break both habits on purpose.
- If an opponent just beat you, consider throwing what would beat your own last throw — many players stick with a winner.
- Against the Mind Reader, feed it a short false pattern for a few rounds, then break it once the score matters.
- Randomising in your head is hard. Tie your next throw to something external — the second hand on a clock, say — to stay genuinely unpredictable.
- In a long match, spend the early rounds observing and the late rounds exploiting what you have seen.
