Coin Flip Online: The Simplest Way to Decide
The coin flip is the most universal decision-making tool in existence. For millennia, humans have relied on the randomness of a coin toss to settle dilemmas, pick teams in sports, or simply choose between two options. Our digital version reproduces this gesture with absolute reliability.
Unlike a physical coin, which can have a very slight bias due to its weight or the way it is thrown, our virtual coin flip uses the browser's Web Crypto API (crypto.getRandomValues). This technology generates a cryptographic-quality random bit, guaranteeing a strictly equal 50/50 probability between heads and tails.
The tool keeps a history of your flips with real-time statistics (heads vs tails count). You can use it for successive series of flips and verify for yourself that the distribution tends towards balance.
No data is sent to a server: the draw takes place entirely in your browser, on your device. The tool works on all modern browsers, including mobile and tablet.
