Is each flip equally likely to be Heads or Tails?

Yes. Each outcome is derived from secure random bytes and mapped to one of the two sides with equal probability.

Why might a short batch contain many results of one side?

Randomness does not force an exact 50/50 split in every sample. Imbalanced short runs are normal, and even larger runs fluctuate around the expected proportion.

Does flipping again extend the previous statistics?

No. Each click creates a fresh result and replaces the displayed sequence and summary rather than maintaining a lifetime total.

Can this simulate a biased coin?

No. The model is deliberately fixed to two equally probable outcomes and does not provide weighting controls.

Coin Flip

Flip a single virtual coin or run a larger batch, then compare Heads and Tails counts, percentages and the full sequence.

Number of coins

Coin flips are generated locally in your browser using the Web Crypto API. Results are not stored or sent to a server.

How to use Coin Flip

1
Enter how many coins you want to flip, from 1 to the supported batch limit.
2
Click Flip coin or Flip coins to create a new independent result.
3
Read the ordered sequence when individual outcomes matter.
4
Compare the Heads and Tails totals and percentages for a multi-flip batch.
5
Choose Flip again whenever you want to replace the current experiment.

Frequently asked questions

About Coin Flip

Some decisions need one clear binary outcome; others benefit from seeing how a random process behaves over many trials. Coin Flip covers both cases, showing one large result for a single flip and an ordered sequence plus percentages for a batch.

The generator uses Web Crypto and does not manipulate results to make the totals appear balanced. That makes natural streaks and uneven samples visible rather than corrected away. Every run occurs locally and begins as a new experiment.
