Is the Coin Flip Fair?
Yes. Each flip uses the Web Crypto API (crypto.getRandomValues) built into your browser, which provides cryptographically secure random numbers. This means every flip is independent and has an exact 50/50 chance of landing on heads or tails. Try flipping 1,000 times to see how closely the results converge to 50%.
