Flip a Coin

Yes. Each flip uses the browser's built-in cryptographic random number generator (crypto.getRandomValues) which provides statistically uniform randomness — far more random than a physical coin toss, which can be influenced by technique, weight distribution, and air currents.

Exactly 50/50 for each flip. Unlike a real coin, which studies have shown has a slight bias toward the side facing up at launch (~51%), our digital coin is perfectly fair with equal probability for both outcomes.

Yes! Use the multi-flip mode to flip 2, 5, 10, or 100 coins simultaneously. Results are displayed in a grid showing each individual outcome along with a summary of totals.

Absolutely. Click the "Custom Coin" toggle to enter your own text for each side. Use it for any two-option decision — pizza vs sushi, study vs play, or any binary choice you need to make.

There's no theoretical limit. The probability of flipping the same result N times in a row is (1/2)^N. So 10 in a row happens about once every 1,024 sequences. The tool tracks your current and longest streak across all flips in the session.

No. Your flip history and statistics reset each time you reload the page. This keeps things lightweight and private — no data is stored on any server or in your browser's local storage.
