Flip a virtual coin for a fair two-choice result
A coin flip is the classic way to settle a simple choice. Select Flip Coin, or tap the coin itself, to reveal either Heads or Tails after the animation.
This free online coin flipper is ready whenever you need a decision without finding a physical coin. The result is easy to see and share with everyone involved.
Use a coin toss for everyday decisions
A virtual heads-or-tails generator is useful when there are exactly two possibilities and both sides are happy to leave the result to chance.
- Start a game Choose who goes first or which side starts.
- Settle a friendly debate Resolve a small tie quickly and visibly.
- Make a binary choice Use Heads and Tails as a simple yes-or-no answer.
- Choose between two tasks Pick the next item when both are equally suitable.
A fresh random result every flip
The coin outcome is generated with the browser Web Crypto API. Heads and Tails are selected from the same two possible outcomes, giving each side an equal chance on every flip.
What a coin flip can and cannot settle
A flip works when both outcomes are genuinely acceptable and the only problem is choosing. It replaces an argument nobody wants to have with a result nobody can contest.
It works badly when one outcome matters more than the other. If you find yourself wanting to flip again, the flip has done something useful anyway: it has told you which answer you were hoping for. Take that as the decision and skip the second toss.
Choosing between more than two options
Two flips give four equally likely combinations, so a coin can pick fairly between four options: heads-heads, heads-tails, tails-heads and tails-tails. Three flips give eight combinations for eight options.
For three options, flip twice and assign one option to each of the first three combinations. If the fourth comes up, discard it and flip twice again. Discarding keeps every option on exactly a one in three chance, whereas folding the spare combination into one option would quietly hand it a double share.
Streaks, and why a virtual coin has no bias
Six heads in a row happens about once in every sixty-four sequences of six flips. In a long session it is unremarkable, and it says nothing about what the next flip will do.
Physical coins are not perfectly fair: studies of real tosses have found a small bias toward the face that was pointing up when the coin was launched, because the coin precesses rather than turning end over end. A virtual flip has no physical starting position to favour, so heads and tails are drawn from the same two outcomes with equal probability every time.

Frequently Asked Questions
How do I flip the virtual coin?
Select Flip Coin or click the coin itself. The animation ends by showing either Heads or Tails.
Are Heads and Tails equally likely?
Yes. The coin flip selects between two possible outcomes using browser-based secure randomness, so each side has an equal chance.
Can I use this as a yes or no decision maker?
Yes. Agree on which side represents Yes and which represents No before you flip.
Is the online coin flip free?
Yes. You can flip the virtual coin for free in your browser without an account.
How do I choose between four options with a coin?
Flip twice and read the pair. Heads-heads, heads-tails, tails-heads and tails-tails are four equally likely combinations, so assign one option to each. Three flips extend the same method to eight options.
How do I pick fairly between three options?
Flip twice, assign an option to three of the four combinations, and re-flip both if the spare combination comes up. Discarding it keeps all three options at exactly one in three. Giving the spare combination to one of the options would double that option chance.
I got six heads in a row. Is something wrong?
No. A run of six matching flips occurs roughly once in every sixty-four sequences of six, so it is common over a session. Each flip is drawn independently, so the run does not make tails any more likely next.
Is a virtual coin flip fairer than a real one?
Marginally, yes. Studies of physical tosses have found a slight bias toward the face that started upward, because a real coin wobbles as it spins. A virtual flip has no starting face, so both outcomes are equally likely every time.
