If you're taking about investing $65,620 a year and making a guaranteed $32,810 profit, you're on to something, but I'm talking about something where the only guarantee is you'll get to play at a greatly reduced cost or get lucky for a short period of time and make a tiny profit. At $20 a drawing, a player would need a four number match every 15 drawings just to show a tiny profit. I got lucky and matched four numbers 4 times in 42 drawings, but that's still only a 42% profit; the rest came from the two and three number matches.
My average daily winnings were about $11.75, but that's including the $1200 I won by matching four numbers in only 4 of the drawings. Out of 42 drawings, I lost money in at least 36 drawings and had a few where I didn't match even two numbers. I'm talking about actual play when the previous day's winnings were usually less then the cost of the playslips I handed the clerk and I had to make up the difference or $16 to $20 when I only matched two numbers or one or zero.
I wasn't projecting a 50% or any profit playing forever or even for 6 months or a year; I'm not suggesting it's a winning system at least by my betting strategy. You won't find very many system makers that will mention the downside or explain why they quit using it.

A full 14 number wheel has 2002 combos and 10 ways to match any four numbers.

"5610 ways to match three for $10"
There are 180 ways to match three numbers in a full 14 number wheel by matching any 4 of the numbers. Since the abbreviated wheel is guaranteed to match one of them, there are no odds against. There are only 55 ways to match any three numbers so there are odds against getting a three number match by using that abbreviated wheel when only three of the numbers are drawn.
Any wheel is only as good as the numbers you use. If you can't match all five numbers, you can't win the jackpot or match four by only matching three numbers. And there is no guarantee winning the jackpot by matching all five numbers by playing any wheel that's less than a full combo wheel.
