Coin Flip Guide: Why Short Runs Look Streaky
Learn how independent flips work and why a run of the same side is no surprise.
What is the Coin Flip?
Set a flip count and this tool simulates that many coin flips, listing each result in order and totalling the heads and tails. It is a simple chance simulation for settling a choice, demonstrating probability, or seeding a game. No physical coin is involved, and a short run can easily lean one way by luck alone.
How to use it
- Set the number of flips.
- Click Flip.
- Read the sequence and the heads and tails totals.
Worked example
For the sample count of 10, the tool returns a sequence of 10 Heads and Tails results plus heads and tails totals that add up to 10; the exact sequence varies on each run.
Does a run of heads make tails due next?
No. Each flip is independent, so past results do not change the odds of the next flip.
Frequently asked questions
Is each flip really fifty-fifty?
Yes, as far as this simulation goes: each flip is an independent random choice between heads and tails.
Why did I get 8 heads out of 10?
Because chance clusters. Short runs often lean one way, and that is normal rather than a fault in the flipper.
