Flip a Coin

People use our virtual coin toss to make simple choices between two options, settle minor disagreements, add chance to games, or teach probability concepts—perfect when a physical coin isn’t handy.

Even with a perfectly fair coin (physical or virtual), you won't always get exactly 50% heads and 50% tails in a small number of flips. This is due to the nature of randomness. The Law of Large Numbers states that as you increase the number of flips, the results will tend to get closer to the expected 50/50 distribution. Over a large number of flips, the results from our tool should reflect this equal probability.

We're working on customization features for a future update. Soon, you'll be able to choose different coin designs and even upload your own images.

• A real coin flip is influenced by physical factors such as the force of the toss.
• Air resistance plays a role in the outcome of a real coin flip.
• The surface on which the coin lands can affect the result.
• Real coin flips are commonly viewed as random, though slight biases can exist.
• Biases may come from factors like coin weight distribution or flip technique.
