In Ontario, Canada, we have a 20/70 keno game where you can pick from 2 to 10 numbers per game while 20 out of 70 total numbers in the field are drawn. This is just as difficult to beat at a profit as any other keno game, even though the odds appear to be and actually are much better than in your New York keno game. Keno is a teaser and a wild roller-coaster ride that will keep you in the poor house.
The game in Ontario is not computerized as of yet, but none of the games here are televised either, so a lot of people may feel that this creates an opening for fraud or abuse at the top levels of the OLG commission which holds and carries out the draws. Of course, no fraud has been publicly detected so far...Who would squeal on anyone if everyone gets a cut?...I have no reason to suspect fraud in our games, but many of the employees at the ticket-vending machines have tried to short-change winners of smaller prize amounts when they supposedly check tickets for customers after a draw. You've all read about that many times if you are paying attention.
I strategically tried to approach my keno game by dissecting its' components into smaller counter-parts, as though I was playing a smaller 6/49 game ( or smaller ) within the 20/70 game. Although I never beat it, it taught me a lot more about the behaviour of the game on the whole.
You will find that many times, if you use only the very first 1 to 49 numbers of my 20/70 game, 12 numbers will be drawn from that 1 to 49-number field, and then utterly ignoring the remainder 50 to 70 number-range of the remaining field. So I was applying 6/49 strategy and wheeling statistics where I would possibly hit 6 numbers out of 49 when 12 numbers are drawn from the field!
That sounds sweet and simple and do-able, but it's not. The odds are certainly much better to hit 6 out of 49 numbers when 12 of those numbers are usually drawn within that 49-number field ( sometimes more, sometimes less ), but the grand prize here in Ontario for accomplishing that is only $1000 ( tax-free ) after all that work and expenditure of resources. The reward is not that great to strive for, so a player will be tempted to go for the better prize categories without thinking about the near impossibilities and astronomical odds of accomplishing the task.
Now, based on my own experiences and keno observations, as well as observations by others in most lottery games, here's the reality of your observations of hitting 10 out of 20 drawn numbers within 35 to 40 numbers picked by yourself within your total 80-number field in New York keno...It's almost gospel truth that if you pick half of the number field by any means...filtering, dart-throwing, numbers which your kids or pets pick out of a hat, etc., etc., etc., When you randomly choose or use half of the total numbers in any playing field, it has proven fairly consistent that half of the total numbers drawn for that game will most likely be present among that " half-of-a-field " which you chose to play against, no matter how you chose it.
Try it...Get the last 10 results of your NewYork keno game, and within those very few 10 recent/last games, see how many number hits usually were drawn from within digits 1 to 40, and then how many hits usually occurred from digits 41 to 80...Go back to last year's draws, or draws from 5 years back, and you will likely discover the same consistent pattern, even if equipment or algorhythm software is changed in between.
So here's your " main " filters as food for thought before you try to refine the process further using any other means or filters...The point I'm making is that it doesn't matter how you choose your numbers...If the game is mostly random with little outside influence or bias or tampering, when you choose half the field to play or wheel against, then usually about half of the drawn numbers will be present in your chosen half of the total field. If you use only one third the entire field, about one third of the drawn results will be present in that smaller field " most " of the time. If you use the whole number-playing field, all drawn numbers will be present, of course.
Check the past few games against these parameters using 40 of the 80 numbers in your NY Keno game to see how many hits actually occurred within these following groups containing 40 of the 80 numbers in the field ( Usually 9, 10, or 11 hits per draw...roughly half of the hits are in half of the field you would pick no matter how you pick it ) :
All 40 of the " odd " numbers from 1 to 80
All 40 of the " even " numbers from 1 to 80
All 40 Numbers from the following 8 groups of 5... 1 to 5, 11 to 15, 21 to 25, 31 to 35, 41 to 45, 51 to 55, 61 to 65, 71 to 75.
All 40 Numbers from the following 8 groups of 5... 6 to 10, 16 to 20, 26 to 30, 36 to 40, 46 to 50, 56 to 60, 66 to 70, 76 to 80.
All 40 Numbers from 1 to 40.
All 40 Numbers from 41 to 80.
All 40 Numbers from the following 4 groups of 10... 1 to 10, 21 to 30, 41 to 50, 61 to 70.
All 40 Numbers from the following 4 groups of 10... 11 to 20, 31 to 40, 51 to 60, 71 to 80.
Pick 40 numbers in groups of twosies, or threesies, or foursies, etc., if you like ... Or use a dart board to pick them...
Etc., Etc., Etc. ...
...Slice 'em and dice 'em any way you want, and see if it isn't so...Half of the number field will get you about half of the drawn hits most of the time...It's those odd, scattered, occasional patterns and anomalies which occur only those very few times during a few draws out of 100 in the course of the game history that you should be seeking to exploit by identifying and quantifying and looking for them, more than searching for any more " Filters "...
