For most people, buying lottery tickets is a waste of money. Think of why governments run lotteries (as a way to increase their revenues,) and why casinos run on a profit-basis. They earn the big bucks from gambling, not the average person.
I did a substantial study of this with my wife who has a generally lucky chart, more so than mine. Using a system I developed by trial and error using the lotto in Pennsylvania, USA, that had 7 three number sets to get for the big win, I was able to dramatically increase her chances. But even when she bought the tickets exactly when I said---within 2 minutes of the time I said(beyond that it didn't work), she still only got 2 or three of the seven numbers. She never got five or six or 7 which was where the serious money was.
I discovered that the key was that at any instance when she was buying she was competing with an enormous number of other people. Also my wife was not buying on her astro*cartography luck line either, which is important to do. The smaller the number in to pool of buyers, the greater her luck compared to others. The time of the lottery has nothing to do with the winning. Its the exact time that you buy the ticket.
So.... you need five things to win:
1. You have to have a basically chart natally
2. You have to be in a lucky period of your life. Some period of life are more lucky than others.
3. You have to be exactly on your Astro*Cartography luck line
4. You have to buy the ticket at an exact time when your luck is strong. Several minutes later it may fall to nothing
5. You have to by dumb luck choose a time when not only you have great luck, but that the other people buying within that two or three moments have either luck than you.

It may be that some numbers are inherantly more lucky than others. So that when you have essentially two people with the same luck at the same time, the one with the luckier number wins. But this would be not the primary issue.
Also there actually are some numbers that you don't want to win with because they are distinctly a bad scene. The tv show LOST had a character in it like this and you can find people who won with loterry numbers that are a bad scene and everything went bad for them after they won. I chose the numbers she should use since I wanted the win, if she got it, to be nice to us, not nasty.
