Flipping
Tap the coin or press Flip. It spins and lands on heads, with the wizard's hat, or tails, with the stars. The counts underneath keep every flip until you press Start again, along with the current streak: how many times in a row the same side has come up.
Fair, every time
Each flip is drawn from your browser's cryptographic random source, so heads and tails are exactly even and one flip never depends on the last. Runs of five or six of the same side are normal: in 100 flips, a streak of at least six turns up about half the time.
Questions
Why flip 10 or 100 at once?
To see the odds even out. A handful of flips can lean far one way; a hundred rarely land far from fifty-fifty.
Is anything saved?
No. The counts stay in this page and are gone when you close it.
