Coin Flip
Flip a virtual coin with a spinning animation to make a quick decision, instantly in your browser.
How to use the Coin Flip
- Click Run to toss the coin.
- Watch it spin and land on heads or tails.
- Click Run again for another independent flip.
How the Coin Flip works
Each flip draws a random value from your browser's cryptographically secure random number generator (the Web Crypto API) and maps it to heads or tails with exactly equal probability. The animation is just for show; the result is decided before it starts.
Every flip is independent, so a run of five heads doesn't make tails any more likely next time. Over many flips the results will settle close to 50/50.
