About this tool
No coin in your pocket? Flip a virtual one. Every flip uses cryptographic randomness for a genuine 50/50 chance, and the running heads/tails tally lets you verify the fairness yourself over many flips.
Perfect for settling decisions, choosing who goes first, or demonstrating probability in a classroom.
How to use

Frequently asked questions

Real coins can be biased by weight and flipping technique; a cryptographic bit cannot.
