How to use it

- Choose best of three or best of five when one toss feels too brutal.
- The tally underneath keeps count across the session, so you can see it really is roughly even.

Questions
Is it a fair 50/50?
Yes. Each toss is an independent draw with an even chance of either side. A real coin is very slightly biased by its faces, this one is not.
Why does it sometimes give five heads in a row?
Runs are normal in random sequences. Five heads in a row happens about once in every thirty-two sets of five tosses.
