Coin Flip Generator
Coin Flip Generator
Enter how many times to flip a virtual coin. This flips that many independent 50/50 coins and shows you the full sequence of results, plus how many landed heads versus tails overall.
Every flip is genuinely independent — each one carries an equal, unaffected 50% chance of heads or tails no matter what came before, since a coin has no memory of previous outcomes despite how tempting "it's due for tails" reasoning can feel after a heads streak. Over a large number of flips the heads and tails counts should land close to an even split, though short runs can and often do show streaks that look surprising purely by chance — a useful, hands-on illustration of how randomness actually behaves over small versus large sample sizes.
- Each flip is independent: every flip has an equal, unaffected 50% chance of heads or tails, regardless of what came before — there's no "streak correction" in true randomness.
- Expect roughly even splits over many flips: with a large number of flips, the heads and tails counts should land close to 50/50, though short runs can easily show a temporary imbalance.
- Useful for quick decisions: a single flip is a fast, unbiased way to settle a two-option choice when you don't have a physical coin handy.
Is this really random?
It uses your browser's pseudorandom number generator, which is more than sufficiently random for games, decisions, and casual use — not intended for cryptographic security purposes.
Why don't I get exactly 50% heads every time?
Randomness doesn't guarantee an exact split in any single run — the closer to 50/50 you'll typically get is with a very large number of flips, per the law of large numbers.
