I believe what you are looking for is 'lotto wheeling' algorithms. If
you google that you'll find there's many samples of popular wheeling
combos for 6 number draws that will claim to result in 3/4/5/6 out of
<numbers drawn odds of winning *IF* the numbers drawn happen to be in
your wheel. There are also what is called 'abbreviated' wheeling combos
which do not include all possible combos of candidate numbers, but
these are based on popular combos with the same win ratio as full
wheels. In any case you need to provide the required 'candidate'
numbers for the chosen wheel. For example...

One popular (abbreviated) wheeling combo generates 42 tickets with a
5 out of 6 odds of winning based on using only 16 candidate numbers.
The full wheel would generate all possible combinations of those 16
candidate numbers.

...where the cost/return ratio of this could be prohibitive at best if
you did not choose the right 16 candidate numbers!

Lotteries are 'random' gaming that do not have any 'mystical' results
attached<IMO, and so there are no 'guaranteed' ways to win other than
playing a full wheel of every possible ticket combo for the numbers
used (ie: 6/39, 6/49, 7/49...)!!!
