How to use it
- Choose how many coins (1 to 10).
- Press "Flip" or Space. The coin spins for about a second and lands heads (gold) or tails (silver).
- The count shows how many heads and tails this visit; "Reset count" starts it again.
Is it fair?
Each flip comes from your browser's cryptographic random generator, so heads and tails are equally likely every time, and no flip depends on the one before. After five heads in a row the next is still fifty-fifty. Flip many coins a few times and watch the count drift towards half and half.
More than two choices? Try the wheel spinner or roll dice instead.
Good to know
- The count is for this visit only and starts again when you close or reload the page.
- If your device is set to reduce motion, the coin does not spin and the result shows at once.
- Some phones play no web sound while on silent.

Questions and answers
Are heads and tails equally likely?
Yes. Each coin is a fair 50/50 draw from the browser's cryptographic random generator, independent of earlier flips, so several heads in a row can happen.
Can I flip several coins at once?
Yes, up to 10 per flip. The tool shows how many heads and tails came up and keeps a running count for this session.
Which side is heads?
The side marked Heads is heads and the side marked Tails is tails. Agree who takes which side before you flip.
