What does the coin flip do?
It simulates tossing a coin, giving you heads or tails at random — a quick, impartial way to make a yes/no decision or settle who goes first. It also keeps a running count of heads and tails so you can flip many times.
Is the flip really fair?
Yes. Each flip uses your browser's cryptographically secure randomness (crypto.getRandomValues) to pick a single unbiased bit, so heads and tails each have exactly a 50% chance. There is no hidden weighting, and the result is decided the moment you click.
When to use it
Settle a decision fairly, choose who goes first in a game, break a tie, or make a random pick when you cannot decide. A digital flip is handy when you do not have a physical coin — and no one can accuse the coin of being loaded.
Heads or tails and probability
Over many flips the split gets close to 50/50, but short runs can look lopsided — several heads in a row is normal and does not mean the next flip is 'due' to be tails. Each flip is independent, so past results never change the odds.
