Tap Flip and watch the coin spin. Call heads or tails first if you want to play for real, flip up to ten coins at once, or run up to a thousand flips in one go and see how close the split lands to 50/50.
The classic way to settle a two-way choice. Flip once to decide who goes first, who pays for lunch or which film to watch. If you want some stakes, use Call it: pick heads or tails before the flip and the tool keeps score of how many you got right.
The tally under the coin tracks every flip in the session: total heads and tails, percentages and your longest streak. Streaks look suspicious but are normal: in a hundred fair flips, a run of five or six in a row is common.
For bigger numbers, use Flip them all to run up to a thousand flips instantly. The split will land near half but rarely exactly on it, and it gets proportionally closer the more you flip, which makes it a handy classroom demonstration of the law of large numbers.

Frequently asked questions
Is the coin flip really 50/50?
Yes. Each flip is an independent, unbiased draw from your device's cryptographically secure random source, so heads and tails are equally likely and past flips do not affect the next one.
Why isn't a big batch exactly half heads?
Randomness clusters. A run of 1,000 flips will land near 500 heads but rarely exactly there. The gap shrinks, proportionally, as you flip more.
Can I flip more than one coin?
Yes. Choose up to ten coins to flip together, or use Flip them all for up to 1,000 flips at once.
What does Call it do?
Pick heads or tails before you flip a single coin. The tool tells you whether you called it right and keeps a running record.
Is a real coin toss fair?
Not perfectly. Studies of real coins suggest they land the way they started slightly more than half the time. A digital flip has no such bias.
Is anything stored?
No. The tally lives in your browser tab and resets when you reload or press Reset tally.
