If anyone is interested, here is a least of all combo's for the cash 3. This chart will help you with the sum and root system. If you can chart your previous two or three months cash 3 midday and evening draws, you will see patterns that is very accurate. Here is a example of my chart I have in excel(This can be done with a pencil and paper also).
MID SUM ROW ROOT
957 21 1 3
191 11 1 2
076 13 3 4
330 6 6 6
200 2 2 2
561 12 2 3
This is a example of Ga midday from last week. What I look for is what row is falling everyweek and what root is falling everyweek. Also you look for what row or root is missing. There are serveral patterns you can follow. I have notice if you wait until the last two days of the week you can see what row or root is missing. Hopefully it is one that is falling everyweek. This will save you a lot of money that is spent through the week unless you are hitting.The key is watching for certain patterns. That's why you need at least two or three months worth of tracking.
