Flip stats
Every flip on this device is logged locally — Premium unlocks the running stats.
How it works
- Click the coin (or press Space). It spins and lands on heads or tails.
- Each result comes from your browser's cryptographic random generator — a genuine 50/50 with no pattern to exploit.
- The tally tracks heads, tails and your longest same-side streak. Flip 10 settles best-of series in one go.
About this tool
A physical coin flip is surprisingly biased — the side facing up when you flip has been measured to win about 51% of the time, and catching versus letting it bounce changes the odds again. A software flip has none of that: every result is an independent, exactly-even draw.
Use it for kickoff calls, settling who goes first, breaking ties, or making the decision you've secretly already made — pay attention to which side you're hoping for while it spins.
FAQ
Is it really 50/50?
Yes — each flip uses your browser's cryptographic random number generator (the same source used for passwords), so heads and tails are exactly equally likely and no flip depends on the previous one.
Can I flip several coins at once?
Yes — the Flip 10 button flips ten independent coins and shows the tally, which is handy for settling multi-round decisions quickly.
