Is it really fair?
Yes. Each flip draws from crypto.getRandomValues, your browser's cryptographically secure random generator, and maps it to a clean 50/50 outcome. There's no hidden bias and no "streak memory" — every flip is independent, exactly like a real coin.
Good for quick calls
Settle an argument, pick who goes first, choose between two options, or run a cricket-style toss. The running heads/tails tally lets you flip many times — handy for demonstrating probability, where results drift toward 50/50 over many tosses.
Frequently asked questions
Is the coin flip truly random?
Yes — it uses your browser's secure random number generator, so each result is a fair, independent 50/50.
Can I flip multiple times?
Absolutely. The tally keeps counting heads and tails until you reset it.
Does it need internet?
Only to load the page. After that, flipping works offline.
