Coin Flip
Flip a coin — heads or tails. Cryptographically random.
How It Works
Click Flip and the coin lands on heads or tails using your browser's cryptographic random number generator. The statistics track your flip history so you can watch the split even out over many flips. Click Reset Stats to start over.
Is It Really Fair?
Yes. Each flip draws from crypto.getRandomValues, a cryptographically secure random source, so heads and tails each have a genuine 50% chance and no flip depends on the previous one. There is no server and no fixed pattern — everything happens locally in your browser.
Frequently Asked Questions
How do I flip a coin online?
Click the Flip button and the virtual coin lands on heads or tails. Flip as many times as you like — the running tally of heads, tails, and total flips is shown below.
Is the coin flip fair and 50/50?
Yes. Each flip uses crypto.getRandomValues, the browser's cryptographically secure random source, giving heads and tails an equal 50% chance. Every flip is independent of the last.
Can I use a coin flip to make a decision?
Absolutely. Assign heads to one choice and tails to the other, then flip. It is a fast, unbiased way to settle a decision or a friendly dispute.
Does it keep track of my results?
Yes. It counts how many heads and tails you have flipped and the total, so you can see the split over many flips. Click Reset Stats to start the count over.
Is the result truly random?
Yes. The outcome comes from your browser's cryptographic random number generator, not a predictable pattern, and everything runs locally with no server involved.
