...Not necessarily the "system", but tracking that digit was. If you can catch that digit and limit the number of plays to get to the WIN, then it will work (profit). here's how I find that digit to play around with. I typically play consecutive pairs only though. 23, 34, 45 etc. It happens a lot in GA. If the digit is 3 im playing 23x and 34x in different orders. Who cares about the actual numbers, the money is in the pattern and positions.
NE way.. in TN using the previous drawing will give you a clue. We're looking for consecutive drawings with the same digit. If you find it, it'll typically come back within 3 drawings. Take a look...
Morning
You can look at this list two ways, for the next consecutive drawing or the next morning drawing. If you look then you'll see that digit 9 is next up. Why? look at 6/6-6/10. It skipped 6/11 so that means it should show up within the next 2 drawings. TN mid 6/11 379. Mark the digit 9 for the next morning drawing too (if you want to REALLY get crafty).
Midday
Looking at this... 8 is next. Why? 6/9, 6/10, then it skipped. It'll show up within the next two drawings... 6/11 EVE 648. Mark the 8 for the next MID drawing.
Evening
Looking at this list... This technique doesn't apply. I'd probably go with that 9 (back up plan) for the morning or just sit out (count my $)!
As with any odds game, you're sure to loose in the end if you keep feeding the frenzy. You can't beat the odds, but if you're disciplined then the only odds that a person should be concerned about are the odds for THAT drawing not for the next 20 or 100 consecutive drawings.
Also... If you only have two drawings make 3 columns of the last 10 drawings. Midday, Evening and consecutive. Look at your state and I might bet that you'll see this occurring over and over again. All you have to do is be able to see it and take advantage of it... ONLY when the opportunity is there.
I try to only play key digits in the 2nd or 3rd positions...just my preference.
