How to flip a coin online
Tap the coin or press Flip. The result appears in under a second. To toss several coins at once, set "Coins per flip" and press Flip again. The tally below counts every coin you have flipped since you opened the page.
The math of coin flips
Every fair flip is independent: the coin has no memory. That is why a streak does not make the other side "due". Still, over many flips the share of heads gets closer to 50%, which is called the law of large numbers.
| Outcome | Chance |
|---|
| Heads on one flip | 1 in 2 (50%) |
| Two heads in a row | 1 in 4 (25%) |
| Five heads in a row | 1 in 32 (about 3.1%) |
| Ten heads in a row | 1 in 1,024 (about 0.1%) |
| Exactly 5 heads in 10 flips | 252 in 1,024 (about 24.6%) |
Making fair decisions
A coin toss is a quick, fair way to break a tie. Agree on who calls heads before you flip. For more than two choices, try spin the wheel or the dice roller, and for numbers in any range use the random number generator.

Frequently asked questions
Is this coin flip fair?
Yes. Each flip uses your browser's cryptographic random number generator, so heads and tails each have exactly a 50% chance, and no flip is affected by the ones before it.
Is a real coin toss 50/50?
Very close, but not exactly. A large 2023 study of about 350,000 tosses found a real coin lands on the same side it started on about 51% of the time. A virtual flip like this one has no such bias.
I got heads five times in a row. Is something wrong?
No. Streaks are normal in random results. Five heads in a row has a 1 in 32 chance, so it happens often if you flip a lot. The next flip is still 50/50.
Can I flip many coins at once?
Yes. Choose how many coins to flip (up to 100) and the tool shows each result plus the count of heads and tails.
What can I use a coin flip for?
Settling a decision, choosing who goes first in a game, picking sides at kickoff, or teaching probability in class by flipping many times and comparing the results with 50%.
