Frequently asked questions
- How do you play rock paper scissors?
- Both sides reveal a hand at the same time. Rock beats scissors, scissors beats paper, and paper beats rock; matching throws are a tie and you replay.
- Does the computer cheat?
- No. The computer picks its throw with cryptographically fair randomness before it sees yours — it can't peek.
- Is there a winning strategy?
- It's random, so nothing guarantees a win — but people tend to throw rock first slightly more often. Since the computer here picks fairly at random, no pattern beats it in the long run.
- Can I play best of 3 or 5?
- Yes — the running score lets you play any best-of match. Just stop when someone reaches the number of wins you agreed.
- Is it free and private?
