Coin Flipper
Coin Flipper virtual coin toss flip multiple coins random heads tailsMake one toss or run a small trial
Enter 1 to 100 coins and press Flip coins. Each position independently becomes Heads or Tails, followed by totals and the ordered result sequence.
What a fair coin model means
Each virtual flip has two equally likely outcomes. One flip does not remember or influence another. Heads after five tails is still a one-in-two possibility; the earlier streak does not make heads “due.” This independence is the useful model behind classroom probability examples and informal tie-breakers.
Worked example
Request five flips. A possible sequence is Heads, Tails, Tails, Heads, Heads. The totals are three heads and two tails. Another five-flip run can repeat that sequence, reverse it, or produce all heads. No particular result is promised even when the number of flips stays the same.
Short runs rarely look perfectly balanced
A fair process does not require exactly half heads in every batch. Ten flips might produce seven heads without anything being wrong. Over many independent trials, the proportion tends to move closer to one half, but local streaks and imbalances remain normal. Do not “correct” a surprising run by discarding it.
How randomness is produced
The page draws random bytes from the browser's cryptographic random source and maps the low bit to one of the two outcomes. This avoids the basic pseudo-random function used in many tiny scripts. Results remain local and are not logged by the tool. Refreshing or flipping again creates a new sequence.
Limits and fair-use cautions
A private browser flip is useful for games, demonstrations, turn order, and low-stakes choices. It provides no shared audit trail and should not decide gambling, regulated drawings, safety questions, legal rights, or valuable prizes. When participants need to verify the toss, use a mutually visible physical coin or a platform that records the event.
Coin Flipper FAQ
Can the same result repeat?
Yes. Repetition and long streaks are possible in a random sequence.
Does the first coin affect the next?
No. Each outcome is generated independently.
Why limit a run to 100?
The cap keeps the sequence readable. Statistical simulations should use specialized software and larger recorded samples.

Limitations of a private virtual flip
Each flip is modeled as independent and equally likely; private results offer no audit trail for regulated or high-stakes decisions.
