Questions
Is a coin flip really 50/50?
Here it is: heads and tails are equally likely. A real coin can be very slightly off depending on how it is tossed, but a virtual coin has no such bias.
Why do I sometimes get a long run of the same side?
Streaks happen in random results. Each flip is independent, so the next flip is still 50/50 after any streak.
Is it really random?
Yes. It uses your browser's secure random number generator, the same kind used for security. Each outcome is equally likely, and earlier results do not affect the next one.
Is anything saved or sent?
No. Names and results stay in your browser and are gone when you close the page.
Is it free?
Yes. No sign-up, no limit.
