The only strategy that is going to work to win a Keno jackpot is a long term strategy. You have to be willing to accept that there will be many drawings where there is absolutely no chance of winning.
While each drawing has 184,756 winning combinations there are over 1.6 trillion potential 10 digit combinations in 80/20 Keno. There are no patterns that occur which reduce potential number combinations down to a playable amount that appear on a daily much less monthly or even annual basis.
As I pointed out earlier if I break the 80 numbers up into group of 4 there are 184,756 combinations of the 20 sets. On average 1000 combinations of those 20 appear daily. This means if I focus on 1 fixed set on average I will have 2 attempts a year where I am choosing from a million different combinations of numbers. The results are only slightly better if I try to dynamically adjust each set on a daily basis.
Within that set on average there are 16 winning sets knocking the odds down from 1 in a million to about 1 in 65,000. If I apply more rules within that set I might be able to know it down to a consistent 1 in 10,000 that occurs consistently once per year.
If I increase the amount of money I'm willing to spend per drawing to 10 dollars then I'm looking at 1 in 1,000 once per year. Over the course of 10 years it goes down to 1 in 100. If I did not win back a single penny then I would have spent roughly 31K however on average I can expect to win back 30-40% of what I spent.
The reason why long term is the only play that works is because as random as the drawings are over time they still have to conform to a certain pattern. in the short term it is simply impossible to accurately predict what set of combinations are going to occur concurrently for 10 digits in an individual or even month long series of drawings because of the shear volume of combinations.
I have run thousands of simulations randomly picking numbers versus using a strategy and so far using a strategy has been the only one that with any sort of reasonable consistency produced a winner. But in all the strategies I had to be will to take a long term view.
