How to use this tool

  1. Enter number of flips.
  2. Select Generate for a fresh value.
  3. Check the method and assumptions below before using the result.

The method, explained

Each flip independently draws a cryptographic random bit and maps it to Heads or Tails. Counts summarize the resulting sequence.

A WORKED EXAMPLE

Ten flips produce ten outcomes. An even number of flips does not guarantee equal counts of heads and tails.

What to keep in mind

The simulation assumes a fair, independent two-outcome coin. It does not model physical coin bias or predict the next real flip.

Common questions

Does a run of heads make tails more likely next?

No. Under independent fair flips, the next probability remains one half.

Will repeated runs match?

Usually they differ, but a repeated sequence remains possible.
