As a true lotto aficionado, for the past two decades, I can give you some inside about lottery software programs:
Some lotto software claim to be more advanced because they use advanced cryptographic libraries, or some other colorful technical terms. Others systems claim to generate truly random numbers by implementing advanced mathematical algorithms. And, few systems promote choosing your own numbers (to place you more in control of the range of numbers) and utilize a wheeling method.
After years of researching the subject, reading several good books (Randomness, Statistical Analysis, Numerology, The Lottery System, etc.), and trying many lotto software systems, I will give you my best advice:
[1] Winning lottery numbers prediction is not possible; big red flag for any software claiming to do such. However by carefully analyzing the draws for the past few weeks (or months), it is still possible to see patterns formed based on the randomly drawn numbers. Thus, it is
important to approach the lottery as a "systematic method" of choosing numbers.
[2] Do a brief research on what most reliable lottery experts, and those who have study lottery systems for years, have to say.
[3] Test if the software system is reliable (i.e. based on research, founded on scientific data or observation, and clearly explained to the consumer in terms easy to understand). It should not be claiming to be more than just a tool to re-enforce the users prefer method to select lottery numbers. Realistically, no system can predict/choose the winning numbers for you, but it should be able to make use of current scientific methods and techniques to help you reduce the odds against you.
[4] Finally, any system that is reliable should have the developer/owner wiliness to let you try it for free, for a reasonable amount of time, and be open to answer any questions/comments the users may have. Further, if the product is so reliable and of sound quality, there should be no problem in offering it to the public at a very low cost (high price does not equate to high quality, it only equate to get rich fast with less customers).
RSTech (use Google search engine) offers some free lotto software downloads and free lotto tips. However, do a little of research first on your own (on the topic of the lottery system), understand how to duplicate some of the lottery systems with paper and pencil (as to be able to verify the software is truly reliable), and do remember that any lotto software is just a tool.
