A: The Full Wheel Generator Plus is recommended only for lotto pools and groups. The software produces only complete wheels which cover every possible combination of the numbers you choose. This makes it very expensive to use because of the number of tickets you have to buy. Gail recommends the newer Filtering Full Wheel Generator which can reduce combinations by adding filters, or Balanced Wheeling^® programs like Wheel Five Plus or Wheel Six Plus to individual lotto players rather than the Full Wheel Generator Plus because you can choose the wheel size that's best for you based on your budget and the minimum win guarantee you want. Both Full Wheel Generator Plus and Filtering Full Wheel Generator are Windows programs that will run on 32-bit and 64-bit versions of Windows XP and above.
