I can tell you that my access to the lotteries has been spotty at best... BUT... I have won the lottery more than 10 times since January with wins as recently as 14 March.
What the previous poster said would make a lot of sense. Although, I was speculating that you could only win a certain number of times in a certain time frame and that was the reason why I was not seeing the lotteries pop up.
Both me and my wife have been seeing the lotteries being erratic and not on regular intervals.
