How it works

Each flip has an independent 50/50 chance of heads or tails, using the browser's cryptographically secure random source
Example

Flipping 100 times might produce a result like 53 heads (53%) and 47 tails (47%) - close to 50/50, but rarely exactly even due to natural random variation.

Step-by-step guide

  1. Set the number of flips - 1 for a single quick decision, or more for a running tally.
  2. Click "Flip" for a fresh result.

Why 100 flips rarely lands exactly 50/50

Each individual flip is an independent 50/50 event, but that doesn't mean a batch of flips lands perfectly even - natural random variation means real results cluster around 50% without hitting it exactly most of the time, similar to how flipping a real coin 100 times rarely gives exactly 50 heads. The more flips you run, the closer the overall percentage tends to drift toward 50/50, a pattern known as the law of large numbers.

Common mistakes

Assuming a streak of the same result means the coin is "due" for the opposite outcome - each flip is independent, so past results have no effect on the next flip's odds.
Reading meaning into a small sample's imperfect split (like 6 heads out of 10) - small samples naturally deviate from a perfect 50/50 split even with a completely fair process.

Frequently asked questions

Is this actually a fair 50/50 chance?

Yes - it uses a cryptographically secure random source giving each outcome an equal, independent probability on every flip, arguably fairer than a real physical coin, which can have very slight, hard-to-notice biases from its weight distribution.

Does the previous flip affect the next one?

No - each flip is completely independent of every other flip, with no memory of past results, exactly like a real fair coin.

Can I use this to settle a real decision?

Sure - it's just as fair as flipping a physical coin, and often more convenient when one isn't handy.
