How to Use

Flips 1 to 100 virtual coins at once. The result appears after a one-second spin, and a running count of heads and tails, with percentages and streaks, builds up underneath.

Set 'Number of coins' with the −/+ buttons or the 1, 3, 5, 10 and 100 shortcuts.

Optionally type your own options into 'Heads label' and 'Tails label', such as Pizza and Tacos. Leave them empty for plain Heads and Tails.

Press 'Flip Coin'. After about a second you get the result; with several coins you see a count such as 'Heads 6 · Tails 4' plus every coin in order.

'Copy result' puts the outcome on your clipboard. 'Recent Results' keeps your last 10 flips, and the trash icon clears the history, the counts and the streaks.

Pro Tips

Agree on who has heads before anyone presses the button. It heads off the 'best of three?' argument afterwards.
For a best of three, flip 3 coins at once and go with the side that shows up more.
Streaks are normal. The chance that five flips in a row all land on the same side is 1 in 16, about 6%, and 'Longest streak' lets you watch it happen.

Use Cases

The most common reasons to flip a coin:

Who goes first

Kick-off, first serve, or the first move in a board game.

Example: One player calls heads or tails before the flip, and whoever wins picks the side or the order.

Choosing between two options

Settle a tied vote or a choice between two equally fine options.

Example: Rename the sides to the two options and the result reads as the answer. If you feel let down by it, that tells you which option you really wanted.

Probability lessons

Show that short runs are streaky and long runs even out.

Example: Flip 100 coins at once: about 96% of the time heads lands between 40 and 60. Compare that with 10 coins, where a 7–3 split is common.

Frequently Asked Questions

Is it really 50/50?

Yes. Each coin draws a random number between 0 and 1 in your browser and gives heads when it is below 0.5. Every coin in a multi-coin flip is drawn separately, and no flip depends on the one before it.

Does renaming the sides change the odds?

No. Only the text on screen changes; each side still comes up half the time. Labels can be up to 12 characters long.

Does the spinning animation affect the result?

No. The result is decided the moment you press the button, and the one-second spin is only there so everyone watches the reveal together. With reduced motion turned on in your device settings, the result appears immediately.

Why did I get tails five times in a row?

Independent flips produce streaks more often than people expect. The chance of any five flips all matching is 1 in 16, and a run of five tails specifically is 1 in 32 (about 3%).
