Frequently asked questions
Is the coin flip really 50/50?
Yes. Each flip uses your browser’s random generator to pick heads or tails with equal probability, so neither side is favored. Over many flips the results even out to roughly half heads and half tails.
Can I flip the coin multiple times in a row?
Absolutely. Just click flip again for each new toss. Every flip is independent, meaning a previous heads or tails has no effect on the next outcome.
Does it work on my phone?
Yes. The coin flip is fully browser-based and works on phones, tablets, and computers. Once the page has loaded it can even run without an internet connection.
Do I need to sign up or pay to flip a coin?
No. The coin flip tool is completely free with no registration. It runs locally in your browser, so nothing about your flips is sent to or stored on a server.
