It's as easy as running the program, clicking the GO button, and waiting for the combination to appear before your eyes.
If you don't like the combination that your local lottery ticket seller gives you, you can always turn to this app to get one more in line with your preferences.
The combination will appear in the lower part: first the numbers and then the stars. You can run it as many times as you like since this sort of app uses values such as the date to randomly generate numbers.
Just remember to the thank the app developer if you manage to strike it rich with a combination generated by this program!
