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.
Which side is heads?
The koala 🐨 is heads and the star ⭐ is tails — the key under the coin says so, so you can assign your two options before you flip. The result is also written out in words.
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 🐨
My own guide told you to decide which option is heads before flipping — and the page never said which face was heads. It does now: the koala is heads, the star is tails, written right under the coin. There's also a Reset tally button for a fresh best of three, the result is read out to screen readers, and if your device asks for reduced motion the coin lands straight away instead of tumbling for two seconds.
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.
