I've been doing a little research on the web and looked up Bushdou's wheels and see it's a twist on abbreviated wheels. There are abbreviated wheels here on this site you can get a platinum membership and use them for free! Me myself I will use Power Wheels from Gail Howard because I have the software. Essentially what Professor Bushdou is suggesting is playing combinations within your wheel that way if some of the numbers are in your field then you win multiple prizes. But power wheels, DN wheels and abbrieviated wheels pretty much achieve the same result which is allow you to play more lines for less money. I can say that when you are on the money with the winning numbers you are on the money.
