Rock Paper Scissors Simulator

The computer picks its move completely at random each round — Rock, Paper, or Scissors each have an equal 1-in-3 chance of being selected. This mirrors a fair, unpredictable opponent with no strategy.

With the fixed strategy, the simulator uses your selected move (Rock, Paper, or Scissors) for every single round in the simulation. This lets you see how a consistent choice fares against a random opponent over many rounds.

The simulator picks a random move for you each round, just like the computer does. This gives you a true random-vs-random outcome and is useful for seeing the expected long-run distribution of wins, losses, and ties.

In a perfectly random game, each player has roughly a 1-in-3 chance of winning any given round, a 1-in-3 chance of losing, and a 1-in-3 chance of tying. Over many rounds, win rates should converge toward approximately 33%.

The computer's moves are generated randomly, so each simulation run produces a different sequence of outcomes. The more rounds you simulate, the closer your win rate will trend toward the theoretical 33% average.

Yes — you can simulate up to 1,000 rounds in a single run. Larger simulations help smooth out variance and give you a clearer picture of the true statistical probabilities of each outcome.

Against a truly random opponent (like this simulator), no strategy can guarantee a better-than-33% win rate over the long run. However, against human opponents, psychological patterns can sometimes be exploited — players often unconsciously favor certain moves.

The table lists each round with your move, the computer's move, and whether you won, lost, or tied that round. It's a detailed record of every matchup across the full simulation.
