• I wrote a comprehensive program to calculate the odds in the widest variety of lotto games, including Powerball, Mega Millions, Euromillions, Keno. There is no need to use a calculator, or, worse, pencil-and-paper. Of course, nobody can cover every possible game and the odds of every possible prize. But the program should be able to respond to most cases. For example, if a lotto-6 game draws a bonus number, you first run the program for '6 of BiggestNumber', then run it for '7 of BiggestNumber'.

There are some interesting results for some games. For example, in the Keno game 80/20, it is much easier to predict '10 of 20' than '0 of 20'. Look at the following report or keep it handy in a casino Keno lounge:
