🪙 Coin Flip

About this Coin Flip

The world's oldest decision maker, always in your pocket. Flip a fair virtual coin as many times as you like and watch the running score: total heads, total tails and your current streak, updated after every flip. Over a long session the totals drift toward fifty-fifty — a tiny live lesson in probability.

How to use it

1. Click Flip the coin.
2. Read the result — crown for Heads, eagle for Tails.
3. Flip again and watch the totals and streak update.
4. Use it to settle any great debate fairly.

Example

After 100 flips you might see something like Heads: 52 · Tails: 48 — close to even, but almost never exactly 50/50, which is perfectly normal.

Frequently asked questions

Is each flip really 50/50?

Yes. Every flip is an independent random draw; previous results do not change the odds of the next flip.

What is the longest streak I might see?

Streaks of 5–6 identical results are common in a long session. A streak of 10 has about a 1-in-1024 chance per run — rare, but it happens.

Does the streak display count both sides?

It tracks whichever side you are currently on: flip Heads three times in a row and it shows a streak of 3 × Heads until a Tails breaks it.
