Coin Flip
Toss a virtual coin for a fair heads-or-tails decision — or a cricket toss, a yes/no answer or your own two choices — with a realistic 3D flip, best-of series and running statistics.
At a glance
- Every toss is a fair 50/50 result from your browser’s cryptographic random number generator.
- A realistic 3D coin in gold, silver or rupee style — with Heads/Tails, Yes/No, Bat/Bowl for a cricket toss, or your own two words or pictures.
- Flip up to 10 coins at once, or play a best of 3, 5 or 7 series.
- Statistics: heads and tails counts and percentages, the current and longest streak, and quick runs of 10, 100 or 1,000 flips.
- Streaks are more common than people expect: in 100 flips there is a 54.6% chance of six or more heads in a row somewhere.

Features
Everything you need, nothing you don’t
Truly random
Not a pattern or a timer — each result uses the same randomness that protects passwords and encryption.
Settle it fairly
Best-of series for bigger decisions, so one lucky toss doesn’t decide everything.
Your own choices
Put names, foods or photos on the two sides and let the coin choose.
See probability at work
Run 1,000 flips in a click and watch the split settle near 50%.
Feels real
A spinning 3D coin, a clink when it lands and a buzz on phones.
Works anywhere
Phones, tablets and computers — press Space to flip on a keyboard.
Chances of streaks
| Event | Chance |
|---|---|
| Heads on one flip | 1 in 2 (50%) |
| Heads three times in a row | 1 in 8 (12.5%) |
| Heads five times in a row | 1 in 32 (3.1%) |
| Heads ten times in a row | 1 in 1,024 (0.1%) |
| Three heads in a row somewhere in 10 flips | 50.8% |
| Six heads in a row somewhere in 100 flips | 54.6% |
Is the next flip “due”?
No. A fair coin has no memory: after five heads in a row, the next flip is still exactly 50/50. Believing otherwise is called the gambler’s fallacy. What does happen is that over thousands of flips the *percentage* of heads drifts towards 50% — try the 1,000-flip button to see it.
