Heads or tails, settled instantly. Each flip draws from your browser's cryptographic random source, so it's a true 50/50 — fairer than a physical coin, which real-world studies show lands the way it started about 51% of the time. The tally tracks your session so you can run best-of-three (or best-of-thirty-one) honestly.

Frequently asked questions

Is a virtual coin flip actually fair?

This one is: each result comes from a cryptographically secure random byte, giving exactly 50/50 odds. Physical flips are slightly biased toward the starting face; software has no such physics.

Why did I get five heads in a row?

Independent 50/50 events produce streaks more often than intuition expects — a run of five happens about 1 in 16 sequences. The tally helps you see the ratio even out over more flips.

Can I flip multiple coins at once?

Flip repeatedly and watch the running tally — it records every result this session. For bulk randomness, the random number generator can produce thousands of 0/1 draws at once.
