How to use it

Press Flip. For several flips at once, set the number first; the last flip is shown on the coin and the count of heads and tails appears below, with every flip in order.

Is it 50/50?

Each flip is one random bit from a generator seeded by your browser’s cryptographic random numbers, so heads and tails are equally likely and one flip does not affect the next. Streaks still happen. In 10 fair flips, a run of three or more of the same side is more likely than not.

Questions

Why did I get the same side five times in a row?

With fair flips, five in a row of a given side has a 1 in 32 chance for any five flips, so it turns up regularly over many flips. Each new flip is still 50/50.
