Tap to flip a virtual coin and get a fair heads or tails result, with a running tally so you can play best of three or best of five.

  2. Watch the coin spin and land.
  3. Use the tally for best of 3 or best of 5.

Coin flip probability

Every flip is independent: after five heads in a row, the next flip is still 50/50. This is the “gambler’s fallacy”, a great classroom discussion. Flip 20 times and compare the tally to 10/10; small samples rarely split evenly.

Need more than two options? Use the yes or no wheel with Maybe, or the dice roller.

Fun facts about coin flips

Research on real coins found a small “same-side bias”: a flipped coin lands on the face it started on slightly more than half the time, around 51%. Spinning a coin on a table can be even more uneven because of the weight of the design. A virtual coin has no such bias, each flip is an independent 50/50 event drawn from a secure random generator.

Heads or tails: does calling matter?

No. Whether you call heads or tails, your chance is exactly 50%. Many people call heads more often, but that only matters in games where the other player can predict you, which is a fun psychology lesson for a classroom.

Coin flip vs. yes or no wheel

A coin always has two outcomes. If you want a “maybe”, a weighted answer or a record of every result, use the yes or no wheel. For more than two options, try the main spinner.
