As many of you know, lately I’ve been in a thorough process of upgrading my lotto software. I’ve discovered many things to improve. Also, I usually receive suggestions from users of my lottery software.

I came across one lotto program that I considered to be a complete application: Combinations.exe. I found now that one more feature could have been added: Generate a reduced set of lotto combinations between 2 lexicographical order indexes. Before the upgrade, the software generated such combinations between an index the user chose and the last lexicographic rank (the last combination in the lotto set; e.g. 13983816). The software user was unable to choose two lexicographical ranks (known also as CSN or combination sequence numbers). You can see a screenshot of the new function:



But Combinations.exe needs a serious aid: Software to show the lexicographic indexes of past lotto drawings. I had already written such software a few years ago: DrawIndex.exe. I discovered that this lotto program could have been improved as well. I added two functions that show the difference in lexico ranks from the previous draw and such difference expressed as a percentage number. Here is the fragment of a report for a 5/43 lotto game:

This is mainly an announcement, not a discussion of new lotto strategies. Just a few words for now. Some lotto players might be attracted by what I call whacky situations. For example, the lines #9 and #10 in the Lexicographical Order column. One values is very low, the other one is very high. One would wait for such rare occurrences that generate significantly fewer lotto combosnations.

Another way is to look for indexes that start with the same digit; e.g. 189672 or 137298. Lexicographical indexes as such might occur more often. Or, even more frequently, combinations ranks between 200000 and 300000, etc. Of course, there will be plenty of combinations generated. This type of lotto strategy requires further filtering.

Yet another lotto strategy can generate several thousands of combinations between 2 combination sequence numbers. A group of players will apply then lotto wheeling to the output file. To the best of my knowledge, my lotto software is still the only one capable of such a task. You use the WheelIn.exe application included in the Bright lotto software packages (Wheels from Files). Just as a test, I reduced 100000 lotto 5 combinations to about 140 lines in a “3 out of 5 lotto wheel”. If I had randomized (shuffled) the 100000-combo output file, the size of the “lotto wheel” would have been significantly under 140 lines.

The updated lotto software is presented in more details on these Web pages:

Lotto Combinations between Lexicographic Indexes: Combinations.exe;
Lottery Software to Calculate the Combination Lexicographical Order or Indexes of Lotto Data Files: DrawIndex.exe.

I have to point out something that may look weird to most people. There are persons who confuse registration to this forum with registration for paid membership to download my software. You don’t want to hear my choice of words (really bad ones!) leveled at a couple of individuals over the past couple of weeks!

Registration to these forums is absolutely free, but it does NOT entail downloading my software for free. Downloading my software requires a special form of paid registration via a signup page: Download Free-to-Use Software with Paid Membership.
Members with paid … membership may download directly the lotto software discussed in this post.

Best of luck!
