Coin Flip
Flip a virtual coin with true 50/50 randomness. Perfect for making quick decisions, settling disputes, or just having fun. Track your statistics and see if luck is on your side.
About Coin Flipping
A fair coin has a 50% chance of landing on heads and 50% chance of landing on tails. This is known as a Bernoulli trial - an experiment with exactly two possible outcomes.
While each flip is independent (previous flips don't affect future ones), over many flips you should see the results approach a 50/50 split. This is called the Law of Large Numbers.
Fun fact: A real coin is actually slightly biased (about 51%) towards the side that was facing up when flipped, due to physics!
How to Use the Coin Flip
Choose Number of Coins
Select how many coins you want to flip at once. You can flip 1 coin for simple decisions, or flip 5, 10, 25, 50, or 100 coins to test probability and see statistical distributions.
Click the Flip Button
Press the "Flip" button to toss your virtual coin(s). Watch the realistic flip animation as your coins spin through the air and land on either heads or tails.
View Your Results
See the outcome displayed immediately - heads or tails for single flips, or a breakdown showing how many landed on each side for multiple coins. Each result is completely random with true 50/50 odds.

Frequently Asked Questions
Is this coin flip truly random?
Yes, our coin flip uses JavaScript's Math.random() function which provides a pseudo-random number generator. Each flip has an equal 50% chance of landing on heads or tails, just like a fair physical coin.
Can I flip multiple coins at once?
Yes! You can select to flip 1, 5, 10, 25, 50, or 100 coins at once. The results will show you how many landed on heads vs tails, and all flips are added to your history.
What is the streak shown in statistics?
The streak shows the longest consecutive run of the same result (either all heads or all tails) in your flip history. For example, "5 heads" means at some point you flipped heads 5 times in a row.
Why might I not see exactly 50/50 results?
While each flip has a 50% probability, small sample sizes can show deviation from 50/50. This is normal and expected. As you flip more coins, the results will trend closer to 50% due to the Law of Large Numbers.
Is my flip history saved?
Your flip history is stored temporarily in your browser session. If you refresh the page or close the browser, the history will be reset. We do not store any data on our servers.
