FAQ
Is this coin flip fair?
Yes. Each flip takes one random bit from your browser's cryptographic random number generator (Web Crypto), so heads and tails each have exactly a 50% chance and earlier flips never affect the next one.
Can I flip several coins at once?
Yes. Pick 10, 100 or 1,000 coins under Coins per flip. The result says how many came up heads and tails, and every coin is added to the counts.
Why do I sometimes get many heads in a row?
Streaks are normal. In 100 fair flips the longest run of one side is usually 5 to 7. The Longest streak line shows yours.
Does the keyboard work?
Yes. Press Space or Enter to flip when the page is scrolled to the coin and no field or link is focused.
Are my flips saved?
Counts and history stay until you press Reset or leave this page. Nothing is uploaded or stored.
