How to flip a coin online
- Choose Coins per flip – leave it on 1 for a classic toss.
- Press Flip the coin. The coin spins and lands on heads or tails, and the result is written underneath.
- Keep flipping as often as you like. The Tally section counts heads and tails with percentages, your current streak and your longest streak.
- Check Recent flips to see the last 50 results, newest first, or press Reset tally to start over.
Features
- Fair 50/50 tosses from the Web Crypto API rather than a predictable pseudo-random function.
- Up to 10 coins at once, each shown separately with a heads and tails count.
- Running tally with totals and percentages for each side.
- Current and longest streak, so you can watch how often long runs really happen.
- Recent flips as a row of H and T markers, newest first.
- Accessible: results are announced to screen readers, and the spin is switched off when your system asks for reduced motion.
Why use Fileora's coin flip
There isn't always a coin in your pocket, and a thrown coin can roll under the sofa or be caught a little unfairly. A virtual toss is instant, can't be influenced by technique, and leaves a record of every result, which settles any argument about who won best of three.
It is free and runs entirely in your browser. There is no account to create, and nothing about your flips is stored or sent anywhere.
When a coin toss helps
- Settling a choice between two options – which film to watch, who takes the first turn, or which of two equally good plans to follow.
- Sports and games – decide who kicks off, serves first or picks sides.
- Teaching probability – flip 10 coins a few dozen times and watch the percentages drift towards 50%, or look at how long the longest streak gets.
- Breaking deadlocks in a team when a discussion has run its course.
A useful trick: if you feel disappointed by the result, that tells you what you actually wanted. The coin doesn't have to make the decision – sometimes it just shows your preference.
Heads, tails and the law of large numbers
Over a handful of tosses, results can look lopsided: seven heads out of ten is not unusual. As the count grows, the share of heads settles closer to half, which you can see in the tally percentages. What doesn't happen is the coin “catching up” – believing tails is due after a run of heads is known as the gambler's fallacy.
Need more than two outcomes? The dice roller handles d4 to d100, and the random number generator picks any number in a range or a name from a list.
