How it works
Coin Flip is a web page that does its work on your own device. Everything you type or choose is worked out by your browser and never sent to a server, so nothing is stored and there is nothing to delete. There is no account, no sign-up and no limit on how often you use it.
Best of three
Flip three coins at once and take whichever side came up most.
Questions
Is it really 50-50?
Yes. Each flip is an independent, unbiased draw; long runs of the same side are normal.
