How Coin Flipping Works
A coin flip is the simplest random event: two equally likely outcomes. Each flip is independent — previous results don't affect future ones. Getting 5 heads in a row doesn't make tails more likely on the next flip (that's the gambler's fallacy). This flipper uses true random generation for a perfect 50/50 split.
Uses for a Coin Flip
Coin flips have been used for thousands of years to make fair decisions. Today they're used in sports (NFL overtime, cricket toss), games, classroom activities, and everyday decisions. The Super Bowl coin toss is one of the most-watched coin flips in the world. A coin flip is also a fundamental concept in probability and statistics.
Frequently Asked Questions
Is this coin flip truly random?
Yes. Each flip uses a cryptographically-seeded random number generator, giving an exactly equal 50/50 chance of heads or tails.
What are the odds of getting heads 10 times in a row?
About 0.098% (roughly 1 in 1,024). Each flip is independent, so the probability of N heads in a row is (1/2)^N.
Can I use this for making decisions?
Absolutely. A coin flip is a classic, fair way to make binary decisions — choosing between two options, settling debates, or deciding who goes first.
