What the coin flip does
Press Flip and a coin spins in 3D before it lands on heads or tails. The side is picked by your browser's cryptographic random number generator, so both sides have exactly the same chance on every flip, and no flip is affected by the one before it.
The tool keeps score while you play. You can see how many heads and how many tails you have, your longest streak so far, and a history of recent flips.
How to flip a coin online
- Call it first. Say "heads" or "tails" out loud before you flip. It keeps everyone honest.
- Press Flip (or the Space bar). The coin spins and lands on one side.
- Use Flip 10 times when you want a quick batch. All ten results are added to the count and the history.
- Read the stats. The counter shows your heads total, your tails total and the longest run of the same side in a row.
- Press Reset to clear the count, the streak and the history and start again from zero.
Ways to use heads or tails
Settle a small decision
Pizza or pasta? Walk or take the bus? Give each option a side and flip. Even if you don't follow the result, notice how you feel when the coin lands. A flash of relief or disappointment often tells you what you really wanted.
Decide who goes first
Board games, card games, backyard sports and whose turn it is to wash up all start more smoothly when a coin decides. Nobody can argue with a flip they called themselves.
Break a tie
Two people want the last slice, or a vote ends in a draw. A coin flip is quick, neutral and over in a second. For more than two choices, try the decision wheel or the random list picker.
Teach probability
Ask students to predict how many heads they will get in ten flips, then run Flip 10 times a few rounds and compare. The running count and the streak counter make it easy to talk about chance, fairness and why small samples wobble before they even out.
Add a twist to game night
Use the coin for quick forfeits, house rules or "this or that" questions. Pair it with the dice roller when a game needs numbers too.
Tips for a fair flip
- Agree on what each side means before you flip. Changing the rules after the coin lands is how arguments start.
- Go best of three for bigger decisions. It feels fairer and only takes a few seconds.
- Expect streaks. Most sets of ten flips include three or more of the same side in a row. That's normal randomness, not a broken coin.
- Reset before an experiment so your count starts at zero.
- Want a plain yes or no? The yes or no wheel spins to an answer, with an optional "maybe".
- Need a number instead? The random number generator picks from any range you like.
Questions
Is this coin flip really fair?
Yes. Each flip uses your browser's cryptographic random number generator, so heads and tails each have a 50% chance every single time.
Is heads or tails more likely?
Neither. Every flip is independent and the coin has no memory, so after a long run of heads, tails is still exactly as likely as heads.
Can I flip a coin several times at once?
Yes. Press Flip 10 times to run ten flips in a row. Every result is added to the heads and tails count and to the history.
What does the longest streak show?
It shows the most times the same side has come up in a row since you last pressed Reset.
Why did I get the same side five times in a row?
Streaks are a normal part of randomness. Over many flips the totals tend to even out, but short runs of the same side happen all the time.
Is an online coin flip the same as a real one?
It gives the same two outcomes with equal chances. A real coin can be nudged by how it is thrown or caught; this one can't.
Are my flips saved or tracked?
No. The flips happen in your browser, nothing is sent to our server, and the site sets no cookies.
