Coin Flip
The simplest decision tool there is. Flip once for a straight 50/50, or flip a thousand times to watch the split converge on even — useful for showing why streaks aren't evidence of a rigged coin.
Fill in the form, then run it.
This tool needs JavaScript. Nothing you enter is ever uploaded.
How to use the coin flip
- Press Flip for a single 50/50 result.
- Raise the coin count to flip many at once and see the split.
- Every flip uses the browser's cryptographic random source.
Coin Flip questions
Why did I get six heads in a row?
Streaks are normal in genuinely random sequences — six in a row turns up roughly once every 32 runs of six flips. A flip has no memory of the flips before it.
Is it really 50/50?
Yes. Each flip is an independent draw from the browser's cryptographic random number generator, with no bias toward either face.
Can I use it to settle a bet?
It's as fair as a physical coin and easier to show on a shared screen. For a group, the yes or no wheel gives everyone something to watch.
