How to flip a coin online

  1. Tap the coin or press Flip (Space works too).
  2. The coin spins and lands on heads or tails.
  3. The tally counts every flip so you can play best of 3 or test probability with a class.

Coin flip probability

Each flip is independent: heads and tails are 50/50 every time, no matter what came before. Streaks still happen — in 100 flips, a run of six or more of the same side is more likely than not. Try it with your class: flip 50 times, record the tally, and see how close it gets to half and half.

Frequently asked questions

Is an online coin flip 50/50?

Yes. The result comes from your browser's cryptographic random number generator, giving heads and tails exactly equal odds on every flip.

If I get heads five times, is tails more likely next?

No. Coins have no memory — believing otherwise is called the gambler's fallacy. The next flip is still 50/50.
