About the Coin Flipper
This coin flipper simulates a fair coin toss using a cryptographically secure random number generator, giving each outcome exactly a 50% probability. Flip a single coin for a heads-or-tails decision, or flip up to 1,000 coins at once and see the statistical breakdown.
A single coin flip is the classic way to make a binary decision fairly — choosing who goes first, settling a disagreement, or making a random choice between two options. When flipping many coins, the results illustrate the law of large numbers: the more flips, the closer the heads/tails ratio approaches 50%.
Frequently asked questions
Is each flip really 50/50?
Yes — each flip uses your browser's random number generator, which produces uniformly distributed values. Streaks of heads or tails are normal and expected; they don't change the odds of the next flip.
How accurate is the bulk-flip mode?
Each individual flip in bulk mode is independent and uniform. With many flips, the heads/tails count converges to 50% — but 'many' means thousands; small samples can swing 60/40 or more by chance.
