I have been tracking root sums in SC for 2 years and have found some interesting trends. I have found that playing all numbers in a group "box" online will net a decent profit as long as you are correct in your assumptions. As your account grows you can begin to combo numbers as long as you can maintain a break-even stategy. I will post my root sum predictions for SC from time to time and begin with RS 7 for midday 6/30/2009.
