About this tool
Flip a virtual coin using your browser's cryptographically secure random number generator — a genuinely fair 50/50 result each time, not a predictable pattern. Handy for settling a quick decision or just satisfying curiosity, with a running tally of heads versus tails.
Frequently asked questions
- Is this actually random?
- Yes — each flip uses
crypto.getRandomValues, the same cryptographically secure randomness source used for generating passwords and security tokens, rather than a simple predictable function. - Should heads and tails come up equally often?
- Over many flips, yes — each flip is an independent 50/50 event, so the tally should trend close to even the more you flip, even though short runs can look streaky by chance.
- Does resetting the tally undo past flips?
- It only clears the heads/tails/total counts shown — it doesn't affect anything else, since nothing is saved once you leave the page.
