Frequently asked questions
Is the result really random?
Yes. Results come from your browser’s cryptographic random number generator (crypto.getRandomValues), so every option has exactly the same chance.
Is it exactly 50/50?
Yes. Each flip is independent with an exactly equal chance of heads or tails. Streaks can still happen, as with a real coin.
Can I reset the counter?
Yes. Press Reset to clear the counts and history.
