Frequently asked questions
Is the coin truly fair?
Yes. We use crypto.getRandomValues, the browser's cryptographically secure source of randomness, which produces an unbiased 50/50 outcome over time.
Why did I get a long run of heads?
Streaks are normal in fair coin flips. The probability of any sequence of length n is the same, so a run of 7 heads is no more unusual than any other specific sequence of seven flips.
Can I use this for serious decisions?
Yes for everyday choices. For situations requiring auditable randomness, like raffles with prizes, use a tool that signs and timestamps the result.
Does the history persist?
The recent history is kept in browser memory for the session. Refreshing the page clears it, which is by design to keep the tool simple.
