Questions
Is it exactly 50/50?
Yes. Each flip is one unbiased random bit from your browser's cryptographic generator.
Why did I get five heads in a row?
Streaks are normal. In 100 fair flips, a streak of six or more is more likely than not.
Can I flip more than one coin?
Yes, up to ten at once. The result shows how many landed heads.
