About Coin Flipping
Coin flipping is one of the oldest methods of decision-making, dating back to ancient Rome. Each flip is an independent event with exactly 50% probability for each outcome.

Can I flip multiple coins at once?Yes! Batch flip up to 100 coins simultaneously. Each flip is independent.
How many flips until I get heads?On average 2 flips, but each flip is independent — no guarantees.
