Press Flip and the coin spins in the air before landing on heads or tails. A running tally counts how many heads and tails you have thrown and shows the percentages, which makes it easy to settle a decision, pick who goes first or play a best-of-three.
For probability experiments, flip 10, 100 or 1,000 coins at once and see the number of heads and tails and the longest streak. Every flip uses your browser's cryptographic random number generator, so heads and tails are exactly equally likely.

Coin flip probability
A fair coin lands on heads with a probability of 1/2 on every toss, no matter what happened before. A run of five heads does not make tails "due"; believing it does is called the gambler's fallacy.
Over many flips the share of heads gets close to 50%, but streaks are more common than people expect: in 100 flips, a streak of six or more of the same side is quite likely. Try it with the 100-flip button.
Frequently asked questions
Is the coin flip fair?
Yes. Each flip is drawn with crypto.getRandomValues, giving heads and tails exactly the same chance.
Is a real coin toss 50/50?
Almost. Research suggests a real coin lands on the side it started on slightly more often, about 51% of the time. A virtual coin has no such bias.
Can I flip many coins at once?
Yes. Flip 10, 100 or 1,000 coins at once to see counts, percentages and the longest streak.
What if I need more than two options?
Use the spin the wheel tool or the dice roller.
