There is one trick you can use: all numbers have the same probability to be inthe winning combination, but some numbers are less picked by played less (typically: numvers that can't be associated with birthdays). Pick those numbers and if you will, you will have to share with less people. Not something l'd recommend though, as I hate games of luck.
