Rock Paper Scissors is a simple hand game played by two participants using three legal hand signals. Despite its simplicity, it rewards timing, psychology, and fair play.
Purpose of the game
Two players reveal hand signals on a shared cadence. Each round is scored by the standard intransitive relationships. Matches can be any agreed length, for example best-of-three or first to five.
Legal hand gestures
- Rock: closed fist.
- Paper: open, flat hand facing down or toward the opponent.
- Scissors: index and middle fingers extended in a V, other fingers folded.
Standard win relationships
- Rock beats Scissors.
- Scissors beats Paper.
- Paper beats Rock.
- Same throw means a tie and immediate replay.
Players may choose any legal throw each round. Patterns, reads, and psychology are part of the strategy, but the basic outcomes never change.
Illegal or non-sanctioned throws
Only Rock, Paper, and Scissors are recognized in formal play. Any other signal is illegal.
Examples include Dynamite, Well, Lizard, Spock, Fire, Water, or any house-rule extension. Casual groups can use variants if everyone agrees, but official play does not.
Cadence, safety, and conduct
- Use a synchronized count, such as one, two, three, shoot.
- Reveal on shoot.
- Keep hands visible and avoid striking or scraping hands together.
- Spectators and coaches should not signal players during a throw.
- Maintain basic sportsmanship. Intimidation, insults, or stalling can be penalized in organized play.
Match length and ending
There is no universal round limit. Players or organizers set the format in advance. Casual players can stop whenever both sides agree.
Quick-start checklist
- Agree on cadence and match format before the first throw.
- Use only legal gestures.
- Reveal together on shoot.
- Replay ties immediately.
- Accept the result cleanly and move to the next round.
Bottom line
The basic rules are simple on purpose. Keep the gestures clear, the cadence synchronized, and the expectations agreed in advance. That is what makes the game fast, fair, and easy to trust.
