The app uses the real physics of a roulette table to calculate possible next numbers thrown at the roulette table! All you have to do is do three measurements (for example with a stop watch) of times and ball rounds and the app will do the rest for you! The app also uses a mathematical calculation to simulate random ball jumps as they are part of the game in real life! Maximize the chances of hitting the right numbers! No win guaranteed! Gambling at your own risk!
