How it works
Press Ask and the page answers yes or no. Each press is a new draw that does not remember the last one, so three yeses in a row is as likely as any other run of three.
Fair by design
Every result comes from your browser's cryptographic random source (crypto.getRandomValues), the one used for encryption keys, not the predictable Math.random, and without the slight bias that simple methods have.
Questions
Is it the same as a coin flip?
Yes, the odds are the same. The Coin Flip shows a coin landing and keeps a count of heads and tails.
Can it say maybe?
No. For more than two answers, put them on the Wheel Spinner or the Random Name Picker.
