I like methods that work. In my back testing Lakerbens pick 3 puzzle over the past 200 games would have produced a profit. see link below for my version of how to test and use it. the data base is ky. just copy and paste your data base on the data sheet. if you don't want to use it for pick 4 then ignore pick 4 data.
there are two other programs included. a new pairs sytem from Lotto Laughs, shows tremendous promise. a separate sheet with her instructions is included.
the third file goes way back to something from Robert Perkins, a 2if3in8 wheel. I have added my own methods. basically I generate a random sequence 0 to 9. use this to create 8 lines. check these for at least 2 hits in the past 10 games, if it passes that test then I check for 200 games. if there is 19 or more hits and there are no 20 game deadspots, I add the sequence to a list. continue checking untill I have 10 lines or I get tired of waiting (control break). 19 is a profit point. 8 lines @$.50=$4.00 *200=800 19*$50=950. any of the lines in theory should produce a profit, what has happened in the past does not always hold true going forward.
questions about how to use these I will try to answer. getting #'s to play, you are on your own.
