Questions

Is the coin flip fair?

Yes. Heads and tails each have a chance of one half. The page uses the secure random numbers of your browser for each coin.

Why do I not get half heads?

A fair coin does not alternate. A run of heads is normal. The share of heads gets close to one half only after many flips.

How many coins can I flip?

You can flip 1 to 100 coins at once. The page counts heads and tails for the flip and for all the flips on this page.

Does the tally last?

No. The tally lives in the page only. If you close or reload the page, it starts at zero. The page saves nothing.

Does my draw go to a server?

No. Your device does the work. The page does not save or send your numbers. Read more about privacy.

Is there a limit?

No. You can use the page as many times as you want.

Do I need an account?

No. There is no sign-up and there are no ads.
