Question 1

Is the flip truly 50/50?

Accepted Answer

Yes. The tool uses crypto.getRandomValues — the same randomness used for cryptographic keys — so each flip is an independent 50/50. Over thousands of flips the ratio converges to 50/50, but short runs can show streaks just like real coins.

Question 2

What does the "longest streak" number mean?

Accepted Answer

It's the longest consecutive run of the same side within your current session. Long streaks are common in truly random sequences — seeing a run of 8 heads in 100 flips is normal.
