How to flip a coin online
- Tap the coin or the Flip button for a natural toss.
- Or flick the coin upward: the harder you flick, the higher it flies.
- It tumbles, lands, bounces and settles on heads or tails.
- Give each side a meaning (“Heads: go out, Tails: stay in”) so the result decides something.
Is this coin flip fair?
Every result comes from your browser's cryptographic random number generator (crypto.getRandomValues), the same source used for security keys. The animation is just for fun: the outcome is drawn first and the physics is solved to land on it, so no option is favored.
Heads and tails each have exactly a 50% chance on every flip, and past flips never affect the next one.
Heads or tails for real decisions
Flipping a coin is a classic way to break a tie, but it's also a mirror. Before you look at the result, ask yourself which side you're hoping for. That hope is often the real decision. Read more in the coin flip trick guide.
