About Rock Paper Scissors

The simplest game in the world turns into a mind game when the AI starts reading you. Pick one of two formats at the start: Classic Rock-Paper-Scissors played best of five, or Lizard-Spock, which adds two extra moves and runs best of seven. After three rounds the AI stops playing randomly and starts using a transition-table predictor: it tracks what you historically tend to throw after your last move, guesses your next pick, and plays the counter. Live stats show your wins, losses, draws, current streak, and win percentage, and your best winning streak is saved locally as the high score. Win in Lizard-Spock and the result spells out the themed verb (Spock vaporizes Rock, Lizard poisons Spock, and the rest of the ten-way matchup chart). Series restart automatically with a running counter, so the duel keeps going as long as you do.

How to Play Rock Paper Scissors

Choose Classic (best of five) or Lizard-Spock (best of seven) at the start. Each round, pick a move: Rock beats Scissors, Scissors beats Paper, Paper beats Rock, and in Lizard-Spock each move beats two others and loses to two others. Matching moves draw. The first to win the required number of rounds takes the series, and a new series then starts automatically. From the fourth round on, the AI predicts your move from your past habits and counters it, so vary your selections to stay ahead. Your best winning streak is tracked as the high score.

Controls

Click or tap the Rock, Paper, or Scissors icon to make your choice. On desktop, press 1 for Rock, 2 for Paper, 3 for Scissors. In extended mode, press 4 for Lizard and 5 for Spock. The game reveals both choices simultaneously after your selection.
