I honestly believe that these states have gone to computer generated drawings to make it easier for them to cheat. I don't think it is so much an individual doing it, but it is the management companies manipulating the results to show that they are profitable. They make a lot of money managing these lotteries and the more revenue they pull in the more they make.
Illinois just went to computer generated and they keep telling us that they have all sorts of security to be sure no-one can hack they system.
I am not as concerned with someone hacking the system after the system is in place as I am with the lottery company writing the original software to cheat. Who is checking that? I believe it was Tennessee that had the problem where the software was not allowing double or triple numbers to be selected and they finally admitted there was a programming error. My question is, why in the world was the software doing any kind of checks on doubles or triples? All the software was supposed to do is pick the numbers 0 to 9 three different times. The only check should have been if the number was between 0 and 9. A 4th grader could have done that.
Illinois fired Northstar (the lottery management company) because they weren't generating the profits they had promised the state, but it doesn't go into effect until 2017. Immediately after it was announced they had been fired, Northstar went to computer generated drawings. I am beginning to think they did it so they could manipulate the results with questionable software and hopefully convince Illinois to keep them as the management company. The jackpot for the Lucky Day Lotto drawing went to I believe a record high and was mysteriously won as soon as people started screaming foul on the Illinois lottery facebook page. Northstar is convinced that the higher the jackpot, the more people will play and the higher the profits will be. So I think they are just preventing a win until a huge jackpot is reached.
We don't have a months worth of data to check yet, but I'll bet once we get enough to test, Illinois will have funny patterns like you are seeing too.
