About This Calculator
This coin flipper simulates an unbiased two-sided coin using your browser’s random number generator.
Flip once for a single decision, or run hundreds of flips to observe the distribution cluster around 50/50. Each flip is independent, so past results never influence the next one.
Generation runs entirely in your browser.

Frequently Asked Questions
Is the virtual coin truly random?
It uses the browser’s cryptographically seeded Math.random — effectively random for everyday use, though not suitable for security-sensitive draws.
Will 100 flips give exactly 50 heads?
Not necessarily — randomness means some variance, but 100 independent flips will typically land between roughly 40 and 60 heads.
