Flip a Coin – Heads or Tails
Tap the coin, press the button or hit Space. Each toss is a true 50/50 from your browser's secure random generator.
To flip a coin online (or toss a coin, as most people say in India), tap the coin or press "Flip the coin": it spins in 3D and lands on heads or tails with exactly a 50% chance each. The result is picked by your browser's cryptographic random generator, so no side is favoured.
You can toss up to five coins at once, play best of three or best of five, and choose a classic gold coin or a rupee, peso or dollar style. Your heads/tails count, total flips and longest streak are kept on this device.
Use it for a cricket or basketball toss, to settle a bet with a friend, to pick who goes first, or simply to make a quick decision.

Heads or Tails: Is an Online Coin Flip Fair?
Yes. Each flip calls crypto.getRandomValues, the same secure random source browsers use for encryption. The result is decided before the animation and is independent of every previous flip. A real coin is very slightly biased – studies of hundreds of thousands of tosses found about a 51% chance of landing on the side that started face up – but this virtual coin has no starting side, so it is a clean 50/50.
Streaks are normal. Five heads in a row happens about once every 32 sets of five flips. If you see a long streak in the stats, that is randomness, not a broken coin. You can test it yourself on the randomness audit page.

When to Use a Coin Toss
Sports toss
Decide who bats or bowls first in cricket, who kicks off in football or who gets the ball first.
The toss before a gully cricket match.
Quick decisions
Two equal choices and no strong preference? A coin toss settles it in a second.
Heads: pizza. Tails: biryani.
Who goes first
Board games, video games, presentations or the first pick in a draft.
Captains call heads or tails.
Maths lessons
Students run 100 flips with the stats panel to see probability and the law of large numbers.
Do heads really come up half the time?
Toss a Coin With Two or More Coins
Choose 2, 3 or 5 coins to flip them together. The result line shows each coin and the total heads and tails – handy for probability homework, for the I Ching method (three coins), or for games that need several tosses at once. For a choice between more than two options, try the decision wheel; for a yes/no answer with custom odds, use the yes or no wheel.
Best of Three Coin Flip
A single toss can feel harsh when something matters. Best of three gives each side more chances: the first to win two flips wins the series. Switch on "Best of 3" or "Best of 5" and the tool keeps the score and announces the winner, then starts a new series.
