Flip a coin online
This coin flip page gives you a fair heads or tails in about a second. Tap the coin or press Flip, and it spins before landing face up. It keeps a running count of heads and tails, tracks your current streak and lists every flip. Use it to decide who goes first, break a tie, or see what 50/50 really looks like.
How the coin flip works
- Tap the coin, press Flip, or hit the space bar.
- The coin spins and lands. The result appears below it: Heads or Tails.
- Check the counts. Heads, Tails and Streak update after every flip.
- Press Flip 10 times to run ten flips at once and get a summary like “6 heads, 4 tails”.
- Press Reset counts to clear the history and start over.
The Flip history list shows every result as H or T, newest first.
What 50/50 means
Every flip is an independent event with two equal outcomes. The coin has no memory: after three tails in a row, the next flip is still a 1 in 2 chance of heads. The belief that tails is “due” is called the gambler’s fallacy, and it catches almost everyone at some point.
Fair does not mean even in the short run. In 10 flips there are 1,024 possible sequences, and only 252 of them have exactly 5 heads. So a perfect 5 and 5 split happens about 25 percent of the time. A 7 to 3 split is not a sign of a broken coin. Over hundreds of flips the share of heads drifts closer to half, which you can watch by pressing Flip 10 times again and again.
Streaks are normal
The Streak counter shows how many flips in a row matched, such as “4 tails”. Streaks feel suspicious, but they are part of randomness. In a run of 10 flips, there is about an 83 percent chance of at least one streak of three or more, and about a 46 percent chance of a streak of four or more.
Try this with a friend. One of you writes down 20 made up flips, the other presses Flip 10 times twice. The real list nearly always has longer streaks, because people switch sides too often when they try to look random.
When to use a coin flip
- Who goes first. The opening move in a board game, the first pick in a draft, or who serves first.
- Tie breakers. Two finalists, two restaurants, two movies.
- Classroom probability. Each student presses Flip 10 times, then the class adds up all the heads and tails on the board.
- Splitting chores. Heads you wash, tails you dry.
- Remote calls. Share your screen on a video call so everyone sees the same flip.
Fair by design
The side is picked with your browser’s cryptographic random generator (crypto.getRandomValues) before the coin starts spinning. A real coin can be nudged by how it is tossed or caught. This one cannot.
If you want an answer to a question rather than a side, try the yes or no wheel. For a quick game with a little more back and forth, play rock paper scissors.
Frequently asked questions
Is the online coin flip really 50/50?
Yes. Each flip draws a number with the browser's cryptographic random generator, and heads and tails each have exactly a 50 percent chance. The side is chosen first, and the animation simply turns the coin to it.
What does the Streak counter mean?
It shows how many flips in a row have landed on the same side, such as '3 heads'. It drops back to 1 as soon as the other side comes up.
What does Flip 10 times do?
It flips the coin ten times at once, adds every flip to the history and the counts, and shows a summary such as '6 heads, 4 tails'.
After five heads in a row, is tails more likely?
No. The coin has no memory. The next flip is still 50/50, no matter what came before.
Why didn't I get 5 heads and 5 tails out of 10?
An exact 5 and 5 split happens only about a quarter of the time. Splits like 6 and 4 or 7 and 3 are common, and the share of heads only settles near half over many more flips.
Are my counts saved?
The heads, tails and streak counts last for this visit. Press Reset counts to start fresh, and note that reloading the page also clears them.
