Tap Flip.
Your flips
Each flip is a fresh 50/50 from your browser's secure random generator. A run of heads doesn't make tails "due".
Coin flip, heads or tails, done fairly. Tap the coin and it lands on one side with an exact 50/50 chance. Want to see what a hundred tosses look like? “Flip 100 at once” does them in a blink and counts heads, tails and the longest run. It’s free and works offline once the page has loaded.
Coin flip results: what’s normal
Flip 100 times and you’ll rarely get exactly 50 heads. The chance is only about 8%. Anything from 40 to 60 is perfectly ordinary, and that covers about 96% of sessions.
Runs surprise people even more. In 100 flips, there’s roughly an 81% chance of a streak of six or more of the same side, and about a 31% chance of eight or more. A run of seven heads looks suspicious. It’s actually what a fair coin does. The “Longest run” box shows yours.
Tails is never “due”
After five heads in a row, the next flip is still 50/50. The coin doesn’t know what happened before, and neither does the generator behind this page. Believing otherwise is the gambler’s fallacy, and it’s behind plenty of bad bets at the roulette table: red coming up eight times doesn’t make black more likely on the ninth spin. You can test it: flip a few hundred times and look at what follows any run in the strip of results.
Is an online coin fairer than a real one?
Usually, yes. Real coins have a small bias towards landing the same way up they started, around 51%, according to experiments where people flipped coins hundreds of thousands of times. This one has no starting side. Each result comes from your browser’s secure random generator, and the animation just shows it.
