How to Play Rock Paper Scissors
Rock Paper Scissors is a classic hand game played between two players simultaneously. Each player selects one of three hand gestures — Rock, Paper, or Scissors — and reveals at the same time. The rules are simple:
- 🪨 Rock beats ✂️ Scissors — Rock smashes Scissors
- ✂️ Scissors beats 📄 Paper — Scissors cuts Paper
- 📄 Paper beats 🪨 Rock — Paper wraps Rock
- Same choice = Draw — Play again
In this online version, the computer picks its hand randomly with equal 33.3% probability for each choice. There is no pattern to exploit — each round is a fresh random selection.
Rock Paper Scissors as a Decision Maker
Rock Paper Scissors has been used for centuries as a fair tiebreaker. Unlike flipping a coin (which requires a physical coin) or pointing at someone (which introduces bias), RPS gives both parties agency — you pick your own move rather than leaving everything to chance.
Common uses:
- Decide who goes first in a board game or card game
- Settle a disagreement between two people fairly
- Pick who pays when splitting a bill
- Choose who gets the last piece of food
- Tiebreak a 1-0 vote in a group decision
For more casual group decisions, try our Spin the Bottle for party tiebreakers, or the Random Name Picker when you need to pick from more than two people.
Is There a Winning Strategy?
Against this computer — no. The computer generates a truly random choice each round. There is no hidden bias, no adjustment to your recent moves, and no pattern. Over many rounds, each choice wins approximately one-third of the time.
In human-vs-human play, psychology matters. Research shows that humans tend to repeat a move that just won, switch away from a losing move, and avoid throwing the same choice three times in a row. Expert RPS players exploit these tendencies — but against a random-number generator, psychology is irrelevant.
Rock Paper Scissors Variations
The classic game has spawned many extended versions. The most popular is Rock Paper Scissors Lizard Spock (popularized by The Big Bang Theory), which adds two more hand signs to reduce the draw rate:
- Scissors cuts Paper, Paper covers Rock, Rock crushes Lizard, Lizard poisons Spock, Spock smashes Scissors, Scissors decapitates Lizard, Lizard eats Paper, Paper disproves Spock, Spock vaporizes Rock, Rock crushes Scissors.
The 5-element version reduces draws to 20% (vs 33% in classic RPS). Our current tool plays classic 3-element Rock Paper Scissors.
