Coin Flip
Flip one or more virtual coins for a quick, fair heads-or-tails decision.
How to use the coin flip tool
Set how many coins you want to flip (usually just 1) and click "Flip Coin(s)." Each coin lands on heads or tails with an equal 50/50 chance, decided using your browser's cryptographically secure random number generator. If you flip more than one coin, you'll also see a heads/tails tally.
Frequently asked questions
Is the flip really 50/50?
Yes. Each flip uses crypto.getRandomValues, the same secure randomness source used for cryptography, giving heads and tails an equal chance every time, independent of previous flips.
Can I flip multiple coins at once?
Yes — set the number of coins above 1 to flip several at the same time and see the result of each one, plus a total tally.
Is anything about my flips saved or tracked?
No — everything happens locally in your browser and nothing is stored or sent anywhere.
