Coin Flip

Each flip draws from your browser's cryptographic random source, the same kind used for security, so there's no pattern and no bias. Heads and tails each get an even 50 percent chance, and the tool keeps a running tally as you go, with percentages and your longest streak. You can flip once or batch many at a time, and it all happens on your device, so you'll get a fresh, fair result every time you tap.

Yes, it's a fair 50/50. The result comes from the browser's crypto random generator, which is built for unpredictability and is far stronger than the basic random function many scripts use. Over a few flips you might see a lopsided run, since that's normal for chance, but across many flips heads and tails settle close to half each. The live percentage shows that balance forming as your count grows.

You can. Set the number of flips, or use the quick buttons to toss 10 or 100 in one go, and the tally updates with the totals. Batch flipping is handy for a probability lesson, a quick simulation, or settling several choices at once. The result card shows how many landed heads out of the batch, and the history strip lets you scan the recent run at a glance.

Plenty of things: making a quick yes-or-no decision, picking who goes first in a game, breaking a tie, or running a fair draw when you don't have a real coin handy. Teachers use them to show probability in action, since a growing tally makes the 50/50 idea concrete. Because it's right in your browser, it's always with you, which beats hunting for a quarter.

On a fair coin, neither, since each side has the same 50 percent chance on every flip. A real coin has tiny physical quirks, but this digital flip is perfectly even. One thing to remember: past flips don't change the next one, so after five heads in a row the odds of heads are still 50 percent. The tally here helps you see that long-run balance for yourself.

Yes, it's completely free, with no sign-up and no limit on how many times you flip. It runs entirely in your browser, so it's fast and private, and nothing you do is sent anywhere. Bookmark it for game night, a classroom demo, a coin toss before a match, or any time you need a fair, quick decision, and you'll have heads or tails in a tap.
