Coin Flip

How it works

Each click calls Math.random() and maps the lower half to heads and the upper half to tails. The animation is decorative — the result is decided the moment you click, not by where the visual settles.

Frequently asked

Is this actually 50/50?

Yes. JavaScript's Math.random() is uniformly distributed, and we map it cleanly into two equal halves. There is no tilt or memory between flips.

How is this better than a real coin?

You always have a coin in your pocket if your phone is in your pocket. It also can't roll under the couch.

Can I do best of three?

Sure — keep clicking. The flips are independent, so the streak you see is just the streak you see.
