I've been working to create an Excel Spreadsheet to create lottery numbers drawn in picture form. Basically a grid. I'd speculate that if lottery numbers are random then in a perfect situation would be a number after being drawn would not be drawn again until all other numbers have been drawn. We know this not to be true. What in theory makes the lottery numbers drawn is that we can't consistently predict what the next drawn numbers would be. So far I'm using the Spreadsheet for Michigan's Lotto 47 by eliminating recently drawn numbers and also eliminating most overdue numbers. Neither is anywhere perfect since for the most part a number drawn frequently is drawn again it the next drawing. More common is the number is drawn again in the 2nd or 3rd drawing. I narrowed the field of remaining numbers then wheeled 9 number for a 4 number payoff for 12 $1 ticket for tonights drawing. The biggest obstacle to winning anything of considerable size is none of the Lotteries pay anything near what lower tier winnings should be. In the case of PowerBall getting 3 numbers out of 70 pays $7 but the odds of winning these 3 numbers if 54,740. So common sense would tell us the lottery games to play are the ones with the least numbers in the field.
