Click the button of the lotto game you want to generate numbers for. The animate button will either cause the balls to bounce or hide them, pushing one of the lotto game buttons will cause them to align and your numbers will appear on top of them. You have two custom games, each one has seven balls, one with 6 standard and 1 special, the second one with 5 standard and 2 special, In the options menu click the column you want to edit, you can enter number 0-999, I don't know of any lotto games that go that high but you at least have that option. Enter your birthday to get your lucky number, every day it will change. You must push the "Generate By" button to change between Random and your Lucky Number. Show as message will display a message box with your lotto numbers. Every option will save automatically. If you need some other lotto game rule, tell me so I can add it in a update.
