Coin Flip FAQ
Is a browser flip really 50/50?
Yes — each flip is one bit from the cryptographic generator, exactly 50/50, which beats a physical coin (real coins have measurable bias from the toss).
I got six heads in a row — broken?
Working perfectly: in 100 flips a run of six is more likely than not. Randomness does not balance itself flip-to-flip; that intuition is the gambler’s fallacy this page politely retires.
