Coin Flip

Flip a fair coin — heads or tails, with a short history of flips.

Coin: —

Even odds. The browser’s cryptographic random source picks the face.

Worked example

Each press of Flip is a fresh heads or tails. Two flips in a row are independent, so heads doesn't make tails more likely next. The last dozen flips stay on the page.

FAQ

Is it a fair coin?: Yes. The browser’s cryptographic random source picks heads or tails with equal chance.
Can I flip more than once?: Yes. Each press is a new flip. Recent flips and a heads/tails count sit under the result.
