A truly fair virtual coin
3D animation
The coin twirls before it lands: all the suspense of a real toss, without digging through your pockets for change.
Multiple flips
Flip several coins at once to play best of three or to watch chance at work over a long series.
History and stats
How many heads, how many tails, and what percentage for each: everything updates with every flip.
Cryptographic randomness
Each result comes from your browser's cryptographic random number generator: neither heads nor tails is favored, and no one can rig the toss.
Heads or tails: really a 50/50 chance?
With a real coin, chance isn't quite perfect. A large experiment with more than 350,000 flips showed that a coin tossed by hand lands slightly more often on the side that was facing up at the start: about 51% of the time. And a skilled flipper can even influence the result. Here, each flip is drawn by your browser's cryptographic random number generator: heads and tails each have exactly a 50% chance, and the coin can't land on its edge or roll under the couch.
After five heads in a row, is tails more likely?
No. A coin has no memory: each flip is independent, and tails still has a 50% chance, even after a long streak of heads. Believing otherwise is so common that the mistake has a name: the gambler's fallacy. In 1913, at the Monte Carlo Casino, black came up 26 times in a row at roulette, and the gamblers who kept betting on red, sure it was “due”, lost fortunes. Streaks are actually common: in 100 flips, you'll almost always see a run of at least 5 identical results. What evens out is the proportion: the more you flip, the closer the percentages get to 50%. That's the law of large numbers.
Break a tie, make a decision, start a game
Who goes first, who does the dishes, who picks the movie: a coin toss settles it between two options in a second, no arguing. In the NFL, in soccer, and in tennis, a coin toss before the game decides who kicks off, picks a side, or serves first. And if you're really torn, flip the coin and watch your reaction: if the result disappoints you, you know what you wanted. To choose between more than two options, use “Spin the Wheel” or the “Random Picker”; to get a number from 1 to 6, the “Dice Roller”.
Frequently Asked Questions
Is an online coin flip really random?
Yes. Each flip is drawn by your browser's cryptographic random number generator: heads and tails each have exactly a 50/50 chance, whatever the previous results.
Which side of the coin is heads, and which is tails?
By convention, heads is the side with the portrait (a face or an emblem), and tails is the opposite side, which often shows the coin's value. Here, there's no doubt: the result is spelled out in full.
Is there a trick to winning a coin toss?
Not here: the cryptographic draw is unpredictable. With a real coin tossed by hand, the side facing up at the start has a very slight edge, about 51%: not enough to make a fortune.
Can the coin land on its edge?
No, the result is always heads or tails. With a real coin, it's possible but extremely rare: roughly once in several thousand flips, depending on the coin's thickness and the surface.
Can I flip several coins at once?
Yes, with multiple flips. All the results go into the history, and the stats show how many heads and tails came up, as a number and as a percentage.
