Fairness and probability
Each flip uses JavaScript’s built-in Math.random() and is treated as an independent 50/50 event. Custom labels do not change the underlying fairness. Previous flips do not influence future results.
Frequently asked questions
Is the coin flip truly 50/50?
The flip is designed to be fair: the result is chosen randomly with equal weighting for heads and tails. Math.random() is suitable for casual decisions and demonstrations, but it is not cryptographically secure.
Can I flip multiple coins at once?
You can flip repeatedly and the tool keeps a running total. A multi-flip mode is available for rapid consecutive flips.
Can I change the labels from heads and tails?
Yes. You can enter custom labels for the two sides, which is useful when the decision is not literally heads or tails.
