How the coin flip works

When you press Flip, the result is chosen at random before the animation starts, using the same secure random source your browser uses for encryption. The coin then spins and lands on that side. The tally keeps count of heads, tails and your current streak, which is a fun way to see the law of large numbers in action: flip 100 times and you will usually land within a few flips of 50/50.

Ways to use a coin toss

Decide who goes first in board games, card games and sports.
Break a tie or make a yes/no decision when you're stuck.
Teach probability: have a class predict how many heads they will get in 20 flips, then test it.
Best of three: flip three times and the side that wins two takes it.

Need more than two options? Use the wheel spinner for a list of names or choices, or the random number generator for any range.

Frequently asked questions

Is the online coin flip 50/50?

Yes. Each flip has exactly a 50% chance of heads and 50% chance of tails, picked with your browser's cryptographic random number generator. Previous flips have no effect on the next one.

Is a real coin toss 50/50?

Almost. Studies of real tosses have found a slight bias toward the side that was facing up when the coin was thrown, roughly 51 to 49. A virtual coin has no such bias.

What are the odds of getting heads five times in a row?

One in 32, or about 3.1%. Each extra flip halves the chance, so ten heads in a row is about 1 in 1,024.

Can I use this to settle a bet or start a game?

Sure. It is commonly used to decide who goes first, who picks the movie or which side kicks off. Call heads or tails before you press Flip.
