Press SPACE to flip
A coin flip with a realistic 3D animation: press Flip (or the space bar) and get heads or tails, announced aloud if you like, with a running tally of results. The outcome comes from your browser's random number generator, so it's a fair 50/50 — the animation just makes it satisfying.
Flip ten times and you might see 7–3 — lopsided runs are normal in small samples. Keep going: after a hundred flips the tally typically sits within a few percent of 50/50, and the gap keeps shrinking proportionally as the count grows. It's a hands-on demonstration of why small samples mislead and large ones converge.
Yes. Each flip calls the browser's random number generator with an even split between heads and tails. Unlike a physical coin, there's no weight bias, catching technique, or edge landing.
No — every flip is independent. After five heads in a row, the next flip is still exactly 50/50; feeling that tails is "due" is the gambler's fallacy.
It's as fair as any coin, so it's a legitimate tiebreaker whenever you'd accept a physical coin flip. For decisions with more than two options, the Decision Wheel or Name Picker handles arbitrary lists.
The tally turns the tool into a small probability lab — useful for classrooms — and settles best-of-N contests without anyone keeping score in their head.
