I use a simple method for each jackpot games (pick 5/ 6 + bonus balls). Looking for the common range of numbers within the history to find the "Normal Rhythm" and pick sets of numbers from it, based on the previous results one can expect what might come up next. The sheets I have for all the games I track are set up the same way, but I find that when looking at these games (GA Fantasy 5, Win For Life, Mega Millions, W.Virgina Cash 25, PowerBall, Texas Cash 5, and Texas Two Steps) they all have different behaviors and "Normal Rhythm" range. Though the range is large, it is much smaller than the entire odds of the game.
Once you're in the "NR", there are many filtering process to optimize the lines you play for a closer chance at the jackpot. If not, you're most likely to win lower tier prizes, everytime. One can use the "NR" to pick 12 numbers and wheel them for best chance at the jackpot, 1 in 792.
Download one of the sheets I have available and plug in the results you want to play, and monitor it. The downfall to the sheets are that they must be done manually. No coding involved in those jackpot sheets to automate the input. Each took me many moons to complete, along with analysis to get the "NR".
It's worth the time because they provide the bird's eye view to the observations. Used more as a guide, that tracks the on going rhythm of the game. Simple method, but have many levels to it.
