Power number systems are a type of wheel with one or more numbers the same in
each combination. Using power numbers reduces the number of combinations, but
the number must be a winning number in order to get the minimum win guarantee.
For example, for a 10 number with 1 power number wheel, you could select numbers 1-11 to be in the wheel,
designating number 5 as the power number. So, each combination produced by the wheel would include the number 5.
You would not have any combinations that left out that number, so if number 5 was not a winning number, it would be
impossible for you to win the jackpot (although a smaller prize is still possible). If number 5 is a winner, however,
your odds are good because a power number wheel gives you higher minimum win guarantees for less money.
