Frequently Asked Questions
Is the coin flip really 50/50?
Yes. It uses crypto.getRandomValues, so heads and tails each have an exactly equal chance — fairer than a real coin, which has a tiny physical bias.
Does it remember my flips?
It keeps a tally for the current session in your browser, but nothing is uploaded or saved after you close the tab.
Can I flip more than once?
Yes — flip as many times as you like; the heads/tails tally updates each time.
Is it random or a pattern?
Truly random — each flip is independent and uses cryptographic randomness, not a sequence.
Notes from Milo 🐨
It used to just flicker and show heads or tails — felt cheap. So I rebuilt it as a real 3D coin that tumbles a few times before it lands. The side it shows is genuinely the result.
