Re: Gaming the system - I am not 100% sure, but the basic lottery is picking 7 numbers from a total of 45 that are drawn each week.
Those normal games are around $15-$20. However, you can buy 'System' entries in the games where you can pick 8, 9 or 10 numbers in a game. That obviously increases your chances of winning, but become increasingly expensive. I believe buying a 10 number system in a game is something in the order of $5000 or similar?
I know there are sites that show lottery draw numbers picked going back many decades. Coin toss theory aside, I am assuming that if someone was to analyse all those numbers and do a statistical probability analysis of the frequency of all 45 numbers, they could form a basic idea of what numbers would likely come up? Combine that with a group of large system entries which increases your chance of winning, and it may be worthwhile.
Like I said above, we are talking six figure sums of money here. If it was just a rich addict without any pattern, then I would expect to see lots of outgoings, but no winnings, however, the winnings with these particular customers seems to be on par with their spending, on a totally random draw, which seems to indicate to me that they have worked out a way to bring up their win/loss ration to at least equivalence, and tipped slightly in their favour.
