I've tried every number generator (Lotto Hat, Lotto Pro, Cheatah, etc) I could find on the internet that was within my budget. None of them has produced consistent results for me. I have a couple that have NEVER come close to picking the right numbers. A couple can't seem to get 20f5!!!
As an alternative, I built my own method of selecting numbers. It begins with substitution of numbers for letters, A=1-9, B=10-19, etc) In a pick 5 of 37 game, there are 435,897 combinations. With substitution, the total is reduced to 56 (AAACD, ABCCD, etc) Breaking the 5-letter combinations down, there are 10 pairs (AA, AB, AC, AD, BB, BC, BD, etc) in positions 1-2, 10 in positions 2-3, etc. There are 20 triples in positions 1-2-3, 2-3-4 and 3-4-5) There are 35 quadruples in postions 1-2-3-4 and 2-3-4-5.
I keep logs of the numbers that come up in each position. In fact, there are 3 logs. I call them Inventory, which is a count of the individual numbers, pairs, triples, etc, Due, which is a list of numbers, pairs, etc, in order of occurrence (some call it hot sheets), and History. I maintain X-Y charts for consolidated pairs, that is, 10 charts rather than 40.
I base my alphabetical sequence and corresponding number selections on the Due lists and X-Y graphs. I build each set of 5 numbers position-by-position. For example, in Texas C5/37, my Due list for P1-2 suggests I should select a combination beginning with BC, AB, AA or AC. Assuming I want to spend $20, I would build 4 sets for each pair. The remaining positions would be based on Due lists and the possibilities. For example, if there is a BC in P1-2, the P2-3 pair has to begin with a CC or CD. I would end up with BCCCD, BCCDD, BCDDD.
I could take another approach and begin my selection with a triple. AAA hasn't come up for a long time. My other data suggests AAACD might be a good choice. Or, I could reverse the process and beging with positions 3.4.5. The data suggests ..CDD would be a good choice.
There are a limited number of 5-letter sequences ending with CDD.
I use the Due lists when picking actual numbers for each position. I keep data for each position. My due list for all numbers suggests 10, 5,29,18 6,20, 22, 8, etc, would be good choices. I would make numbers assignments in conjunction with other lists. For example, data suggests 8, 9,5,6 would be good choices for any combination with A in first position. 14, 17 16, 18, could be winners for combination beginning with a B. If I were to use 6 in position one with A in position 2, the X-Y graphs show that 6.8 has come up more often than 6.7 or 6.9.
Bottomline, the lists, charts, graph present suggestions for every possibility. In practice, I try to use every number at least once. Of course, my success or failure depends on how well I interpret the data. I'm very good at picking 2/5, which pays $2!!!! I usually play my final selections for minimum of 3 drawings, depending on results.
The system, if it can be called that, works with any pick 5 game. It also works with Pick 6, but emphasis is placed on expanding on the pair in P3.4. There a limited number of triples in P1.2.3 and 4.5.6, regardless of the pair selected.
Keeping the data up to date is daily chore, but not overwhelming. I guess it depends on how serious a player is. I've been doing this since the lottery started in Texas. I had many 3/5 when we had a pick 6 lottery, both 6/50 and 6/54. I haven't had a lot of success with pick5/44 and 1/44, but we've only had 74 drawings. MegaMillions is new, but charts for 5/52 and 1/52 are being developed.
I have charts for Pick4/35 and 1/35, but haven't used them that often, since I prefer pick 5.
Would appreciate comments.
