🪙 Coin Flip
Quick answer
A fair coin lands heads or tails with exactly 50/50 odds on every flip, and past flips do not change future ones. This flipper decides each flip with crypto.getRandomValues — your browser’s secure random source — so long streaks of heads are just as natural as alternating results. Over 1,000 flips you can expect heads close to 500 times, give or take a few dozen.
Pick your call and flip.

Frequently asked questions
Is the online coin flip really 50/50?
Yes. Each flip uses one cryptographically random value with two equally likely outcomes, and flips are independent — the coin has no memory of earlier results.
Why did I get heads six times in a row?
Streaks are surprisingly common: in 20 flips there is about a 77% chance of at least one run of 4+ identical results. A streak does not make the next flip any more likely to change.
Can I flip for a real decision?
Of course — a coin flip is a time-honored tiebreaker precisely because nobody can influence it. It is used everywhere from sports tosses to research randomisation.
