Flip a Coin
Flip a coin online and get heads or tails, 50/50. This virtual coin flip uses your browser's secure random tool to pick the result before the coin turns. The animation cannot change the outcome.
Use it to answer a yes or no question, pick who goes first, or break a tie.
How to Flip a Coin Here
- Call it first. Say "heads" or "tails" before you flip. A call after the result does not count.
- Press flip. The coin spins and lands.
- Stick to the result. The whole point of a coin flip is that it is final.
Heads or Tails Coin Flip: What Are the Odds?
On a fair coin, each side has a 50% chance every time. Some results surprise people.
| Question | Answer |
|---|---|
| Heads on one flip | 50% |
| Heads three times in a row | 12.5% |
| At least one head in 3 flips | 87.5% |
| Exactly 50 heads in 100 flips | about 8% |
A streak of heads does not make tails due. The coin has no memory, so the next flip is still 50/50.
Flip a Coin 3 Times
Three flips give 8 equally likely results: HHH, HHT, HTH, HTT, THH, THT, TTH and TTT. Use it for "best of three", where the first to win two flips wins. It is not fairer than one flip, but it feels more satisfying.
To flip a coin 3 times, set the mode to "Best of 3" and press flip until one side has won two flips. The tool counts heads and tails for you and lists your last 20 flips.
Flip a Coin 100 Times
Flip 100 times and you will get close to 50 heads, but rarely exactly 50. A normal spread is about 5 either side, so 45 to 55 heads is common. This makes a good class experiment. Each student flips 100 times, records the number of heads and compares.
Virtual Coin Flip vs a Real Coin
A real coin is physical. Researchers who filmed coin flips in detail found that a coin lands on the side it started on slightly more than half the time, about 51%. A virtual coin flip has no such bias, because nothing is thrown. Each side gets exactly 50%.
Yes or No Coin Flip
A coin flip is a quick way to answer a yes or no question. Let heads mean yes and tails mean no, and say so first. Our yes or no wheel does the same job, and works better when a group is watching.
Say the deal out loud before you flip, like "Heads, I choose the film. Tails, you choose." Then nobody can change the meaning afterward.

Team sides. Heads for one side, tails for the other. For more than two teams, use the random team generator.
For more than two outcomes, spin the random number wheel, or try 1 to 4 and 1 to 6.
Rigged Coin Flip: Can It Happen Here?
No. The result is not stored anywhere before you press flip, and there is no hidden setting. Our How it works page explains the draw. A real coin can be rigged, for example by a trained flipper or a two headed coin. That is why you should call the side before the flip and watch it land.
Frequently Asked Questions
Is the coin flip really random?

Can I flip a coin online for a quick yes or no?
Yes. Decide first that heads means yes and tails means no, then flip.
Is a coin flip fair for important decisions?
It is fair, but a coin should not decide big things like health, legal or money matters. Use it for small choices.
What is the best way to flip a coin for a decision?
