How to Play Rock Paper Scissors
Rock paper scissors is one of the world's oldest decision-making games, originating in China as "shoushiling" and spreading globally. This free online version lets you play against a random computer opponent with match modes and full statistics tracking.
The Rules
Three choices, three matchups: Rock crushes scissors, scissors cuts paper, and paper covers rock. If both players choose the same option, the round is a draw. The classic hand game is a 3-symbol balanced system where each choice beats one and loses to one other.
Match Modes
Choose best-of-3 for a quick 2-round match, best-of-5 for a medium match requiring 3 wins, or best-of-7 for a longer contest needing 4 wins. In each mode, the match ends as soon as one player reaches the required wins — you don't play out remaining rounds. Endless mode plays indefinitely while tracking cumulative stats.
Win Rate Statistics
The stats section tracks your cumulative performance across all rounds in the session. Against a truly random computer, expected win rate approaches 50% (excluding draws) over many rounds. If your win percentage is above 50%, you're running hot — enjoy it while it lasts. Stats reset when you refresh the page.
Is It Possible to Beat a Random Opponent?
Against a computer making uniformly random choices, no strategy improves your long-run odds — the math is locked at 1/3 win, 1/3 loss, 1/3 draw for each round. Against human opponents, there are exploitable tendencies: beginners often throw what beat them last time, people default to rock under pressure, and winners often repeat their choice. These patterns don't apply to this random computer, making it a fair 50/50 challenge.
FAQ
Is this rock paper scissors game really free?
Yes, completely free with no signup required. The game runs entirely in your browser — no server or account needed.
Is the computer's choice truly random?
Yes. The computer uses JavaScript's Math.random() to pick rock, paper, or scissors with equal probability (33.3% each). There are no patterns or memory — each round is completely independent of previous rounds.
What is best-of-3 mode?
Best-of-3 means the first player to win 2 rounds wins the match. Best-of-5 requires 3 wins, best-of-7 requires 4 wins. The match ends as soon as one player reaches the required wins — no need to play out remaining rounds.
What are the rules of rock paper scissors?
Rock crushes scissors, scissors cuts paper, and paper covers rock. If both players choose the same option, it's a draw and that round is replayed (or scored as a tie, depending on mode). It's a classic zero-sum game invented in China and widely played worldwide.
Does the game track my win percentage?
Yes. The stats section shows your total wins, losses, draws, and win percentage across all rounds played in the current session. Stats reset when you refresh the page.
What is the best strategy for rock paper scissors?
Against a truly random computer, no strategy improves your odds beyond 50% (excluding draws). Against humans, people tend to throw the option that beat them last round, throw rock first when stressed, and repeat winners. These exploitable patterns don't apply to a random computer opponent.
