Flip a Coin
Flip a coin online — a fair 50/50 heads-or-tails toss with a big animated coin, a running tally and crypto randomness. Settle any decision in one tap.
One flip, zero arguments
“Flip a coin” is the world's fastest dispute resolver: who goes first, which game to play, pizza or tacos. This version adds the classroom essentials the real coin lacks — a tally that proves the 50/50 split over time, digits big enough for the whole class to see, and randomness you can audit on our fairness page.
Need more than two options? Use the Yes or No wheel, the dice roller for numbers 1–6, or the full wheel of names for anything else.
FAQ
Is this coin flip really 50/50?
Yes — every flip uses the browser's cryptographic random source (crypto.getRandomValues), so heads and tails are exactly equally likely. Run our fairness test to verify it yourself.
How do I use a coin flip in class?
Settle any two-option debate instantly: which team goes first, this-or-that brain breaks, review-game choices, or probability demonstrations — flip 10 times and compare the tally to the expected 50/50.
Does the flip keep a history?
Yes — the tally counts heads, tails and total flips in this browser. Nothing is uploaded; reset it any time.
Can I flip a coin 100 times at once?
One tap is one flip — but the tally keeps counting as fast as you can tap, and the counters show you exactly how close you are to an even split.
