A perfectly fair coin

Researchers have found that real coin tosses land on the side they started on slightly more often than half the time. A virtual coin has no starting side and no thumb technique: each flip is a fresh 50/50 draw from your browser's cryptographic random generator.

Flip 10 or Flip 100 to run a quick experiment. You'll see the heads/tails ratio drift around 50% and settle closer to it as the number of flips grows — the law of large numbers in action.

Frequently asked questions

Is a virtual coin flip 50/50?

Yes. Each flip has exactly a 50% chance of heads, chosen with your browser's cryptographic random number generator.

Why did I get five heads in a row?

Streaks are normal! Five heads in a row has about a 1-in-32 chance, so it happens fairly often over many flips.

Can I flip more than one coin?

Use Flip 10 or Flip 100 to flip many at once and see the totals.
