How to Flip a Coin Online
This virtual coin flip works just like tossing a real coin, without the coin rolling under the sofa.
Choose how many flips
Pick 1 flip for a quick call, or choose 3, 5 or 10 flips for best of three, best of five or a bigger sample.
Flip the coin
Press Flip coin, tap the coin itself or press the space bar. The coin spins in the air and lands on heads or tails.
Check the tally
Heads, tails, total flips and your current streak update after every toss. Your last 30 results appear as chips, so you can see the pattern at a glance.
Heads or Tails: Is This Coin Flip Really 50/50?
Yes. Every toss uses your browser’s secure random number generator, the Web Crypto API. Heads and tails each have exactly a 50% chance, and nothing on the page can tilt the result.
Each flip is independent. A coin has no memory, so five heads in a row do not make tails “due” next time. Streaks like that are a normal part of randomness, and our guide is spin the wheel random? explains why random results often feel streaky.
A real coin is actually a little less fair. Studies of physical coin tosses, including work by statistician Persi Diaconis, found a slight bias toward the side that was facing up before the toss, roughly 51 to 49. An online coin flip removes that bias completely.

When to Use Heads or Tails
A coin toss is the fastest fair way to settle any choice between two options.
Settle a tie or a debate
When two people want different things and both options are fine, a coin flip ends the discussion quickly and nobody can claim the result was biased.
Decide who goes first
Board games, card games, kickoffs and turn orders all start more smoothly when a neutral toss decides who begins.
Break your own indecision
Assign each option to heads or tails and flip. If you feel disappointed by the result, that tells you which option you really wanted.
Teach probability in class
Set the flips to 10 and toss a few rounds. Students can record the results and watch the split move toward half and half as the total grows.
Best of Three and Multi-Flip Mode
Set Flips to 3 for a classic best of three. The coin is tossed three times at once and the result tells you which side won, for example “Heads wins (2 heads, 1 tail)”. Choose 5 for best of five, or 10 when you want a bigger batch of results for a game or a classroom experiment.
Every toss in a batch is added to the tally and the history, so you can keep flipping and track the running totals.
Who Calls Heads or Tails?
The usual etiquette is that the person who is not flipping calls heads or tails, ideally before the coin lands. In American football, the visiting team captain calls the toss before kickoff.
With an online coin flip, say your call out loud before anyone presses the button. That way nobody can change their mind once the coin starts spinning.
Coin Flip or Spinner Wheel?
A coin flip is perfect for two options. If you would rather work with numbers, the pick a number 1 or 2 wheel gives the same 50/50 odds. For a straight answer to a question, try the yes or no wheel, or ask the Magic 8 Ball for a more playful reply.
When you have three or more choices, a spinner wheel is the better tool. Use the pick a number 1-3 wheel for three options, or add your own list to the Wheel of Names and spin.
