Rock, paper, scissors

Everybody knows the rules. What makes this a game rather than a coin toss is that both throws are sealed and revealed together, so nobody can wait and react.

Play Rock, paper, scissors Leaderboard

The rules

  1. Rock blunts scissors, so rock beats scissors.
  2. Scissors cut paper, so scissors beat paper.
  3. Paper wraps rock, so paper beats rock.
  4. Both players choose at the same time, in secret. Neither throw is revealed until both have been made.
  5. Two identical throws are a tie. Nobody scores and the round is replayed.

How a match ends

  1. A match is best of five rounds: the first player to win three rounds takes it.
  2. A match therefore lasts between three and five scoring rounds, plus any ties, which do not count towards the five.
  3. A resignation or a missed deadline ends the match against that player.

Because it is played by correspondence rather than face to face, your throw is sealed the instant you make it. There is no possibility of seeing theirs first, and no advantage in going second.

Rock, paper, scissors terms

Playing it here

  • Against a person or the bot. The bot needs no account and starts at once. To play a person, be rated and keep your games, you need an account: an email address and a password.
  • At your own pace. Every move has a deadline you both see, from one minute to a week. A game can take an evening or it can take a fortnight.
  • Nothing to buy and nothing to win. No stakes, no prizes, no boosts, no undo. The only thing on offer is a place on a leaderboard, and only if you want one.
  • Every game can be checked. Anything decided by chance comes from the game's seed, and the seed is published the moment the game ends, so any finished game can be replayed and verified by anyone. See fair play.
