How to Use It
- Flip
- Tap the coin, press the Flip button, or hit Space. Heads is the crown, tails is the lion.
- The tally
- Every flip is counted, and the last 50 are shown as a row of H and T chips. Your tally is saved on this device, so it's still there tomorrow. Clear Tally starts again from zero.
- Best run
- The longest streak of the same side in a row. Runs of four or five are much more common than people expect!
- Try this
- Flip × 10 and look at the Heads %. It's often nowhere near 50 — maybe 80% or 30%. Now press × 1000 a few times and watch the bar settle close to half and half. A coin has no memory, but the more you flip, the closer the average gets to fair. That's the law of large numbers.
- Is it really fair?
- Yes — each flip is an independent 50/50, and nothing is nudged by what came before. A long run of heads does not make tails "due" next.
