## 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.

## Rock Paper Scissors Tips & Strategies

1. Avoid falling into predictable patterns like always choosing Rock after a win, because after three rounds the AI starts countering your habits.
2. Mentally randomize your choices using external cues rather than gut feelings, which tend to create patterns the predictor exploits.
3. Remember the AI bases its guess on what you played after your previous move, so changing your follow-up tendencies throws it off.
4. In Lizard-Spock, learn all ten matchup relationships before committing to the longer best-of-seven series.
5. Chase a long current streak, since your best winning streak is what gets saved as the high score.

## Frequently Asked Questions

### Is Rock Paper Scissors just luck?

Against a random opponent it would be. But after three rounds this AI uses a transition-table predictor, guessing your next move from your past habits and playing the counter, so winning consistently means staying unpredictable.

### What modes are there?

Two: Classic Rock-Paper-Scissors played best of five, and Lizard-Spock, which adds two extra moves and runs best of seven. Each move in Lizard-Spock beats two others and loses to two others.

### How is the high score determined?

The game tracks your wins, losses, draws, current streak, and win percentage. Your best winning streak, the most consecutive rounds you have won, is saved locally as the high score.
