Flip a coin is a simple way to solve the problem. Most coins have a human head on the obverse which can represents "yes", and the reverse side represents "no". In theory, the probability is half. There are some magic tricks that can manipulate the result of coin flipping, so using this application will be fairer. This application uses a more randomized crypto function ( crypto.getRandomValues ) instead of a common built-in random function ( Math.random ). Users in some countries can see real coins on this page, but if this causes any problems, please let us know. Please follow the local laws and the user is responsible for any violations.
