Frequently asked questions
Is the coin flip really 50/50?
Yes. Every flip uses your browser’s cryptographic random number generator, so heads and tails are exactly equally likely and each flip is independent of the last.
Can I flip several coins at once?
Yes — choose 2, 3, 5, 10, 25 or 100 coins. You see every coin and how many landed on each side.
What is “best of 3”?
The first side to win the majority — 2 of 3, 3 of 5 or 4 of 7 flips — wins the match. The score is shown after each flip.
Can I use my own coin?
Yes — rename the sides (for example Yes and No, or two names), pick a Rupee, Dollar or Euro style, or upload a picture for each side. Pictures stay on your device.
Can I use the keyboard?
Yes — press the Space bar to flip.
