About coin flipping
A coin toss is the classic way to make a random 50/50 decision. Each flip is completely independent — previous results have no effect on the next.
FAQ
Is this truly 50/50?
Yes — each flip uses your browser's random number generator. The probability of heads or tails is exactly 50% every single time, regardless of previous results.
Does past results affect future flips?
No — each flip is statistically independent. Getting 10 heads in a row does NOT make tails more likely on flip 11. This is called the "gambler's fallacy."
Can I flip multiple coins?
Yes — use the + button to flip up to 10 coins at once. Heads and tails counts are shown for each batch.
What is the gambler's fallacy?
The incorrect belief that past random events affect future ones. In a fair coin toss, the odds are always exactly 50/50 — no matter what happened before.
