Keno - Question on random pics distribution on the cards.
However, 17/3 or bigger should happen only about once every 1800 games.
Quote: PierretoI signed up on a site to play Keno about a week ago and have tried a bunch of combinations, etc. to find something I am comfortable with. I have played about 1600 games and documented the wins so I would have something to compare with. I have noticed that the 17/3 splits or bigger have happened at least at least a dozen times or better. I only noticed it a few times. Most of the time I was making notes and didn't look at the picks, just the winning amount. I noticed a few times also that there were quadrants with no hits at all. In the Casinos I play in LA. I have never seen anything bigger than a 12/8 split. That is what prompted my question. Also I noticed that while watching a bunch of YouTube videos, seems like all the big wins that are shown are with large splits in their favor. I noticed this difference on every machine I played in LA. at the 3 casinos that I have visited. Just seems really strange to me?
Think of the different Keno numbers the same way as playing a Pick-40 game of Keno. In fact, there is such a Video Keno game known as Top/Bottom Keno. Since you're asking specifically about 13 numbers, let's find the probability of hitting 13 of 40 with 20 drawn:
nCr(40,13)*nCr(40,7)/nCr(80,20) = 0.0634574402209682 or 6.346%
You can check out the analysis of Top/Bottom Keno on Wizard of Odds for full probabilities of 40 numbers hitting x based on 20 drawn:
https://wizardofodds.com/games/keno/appendix/8/
The probability of hitting 13 (or more) of twenty is 0.09803998, or 9.803998%. You'll see this just under one in ten games, so it's hardly startling.
I don't know precisely what you mean by, "Quadrants," so please identify exactly what you mean by that and I'll address that.
Quote: ThatDonGuyActually, a 13/7 or bigger split should happen in about 1 game out of 5.
Not quite, because you're double counting the same game. For instance, you're looking at 13 and 7 as both rather than just one or the other. If it is 13, then it is also 7.
Didn't really read everything you said, however there's variations of keno and if you believe its skewed towards the top or bottom half, or it has patterns, you'll be rich.Quote: PierretoKeno - Have a question on on the Keno hits. I noticed that on the You Tube Keno wins lots of times the 20 hits are not distributed equally among the 80 numbers. I have seen as many as 17 of the 20 hit in the upper or lower 40 numbers. I have also seen a quadrant without any hits at all at times. I have been playing Keno for a couple of years in LA. and have never seen this before. The biggest difference I have ever seen in LA. is maybe 12 numbers picked in one half and 8 in the other. Most always 10/10 split top/bottom. Why the difference? You could look at this as a + then again it could be a - depends on how you are playing it. Would appreciate any info that you can shed on this subject because I am really puzzled. Thank you!
Let me explain.... the keno makers know people see selective memory patterns like this. That's exactly why they came out with keno variations such as Top and Bottom keno and Pattern keno.

That's what the OP wanted to know - how often is the split between the two halves 13/7 or greater; not how often do 13 or more of the 20 numbers fall into a particular half.

I think by quadrant he means the 20 numbers in each section divided by top/bottom and left/right.

My mistake, then, I misinterpreted him. So, basically, the number you gave and double the number I gave.

Not very likely. I have a spreadsheet with exact values ( well as exact as Excel does). Can upload it later if you want.
Out of 100 games:
10/10 split - 19 times
11/9 - 27
12/8 - 25
13/7 - 19
14/6 - 8
15/5 - 2
1 round with no numbers in one
of the quadrants.
ex. 11/9 could also be 9/11 split with top half
and bottom half, etc.
In the couple of years of playing Keno on the Game King Machines in Louisiana at 3 different Casinos, I have never seen any split > 13/7. In fact, I have never counted a 13/7 split. Mostly all are 10/10 or 11/9 and some 12/8. Anything greater than that (ex. 14/6 or 15/5) is unheard of. Also quads with no numbers drawn in them just doesn't happen. I was just wondering why sites I go to and You Tube posted winners have some games with > 13/7 like 15/5. Just trying to find out why the difference? I would think that anything regulated by the government has to have a way to set win/loss ratios. If you happen to choose your numbers in the upper half and you get a 15/5 split with the 15 numbers drawn showing up on the top half, your odds of winning something would be much greater than if you had picked your numbers for the same game on the bottom half. Also, if you are playing Keno and your games have a more balanced distribution from top to bottom or in each quad, you would at least feel like you had a better chance at winning with at least 5 numbers showing up in each quad. Of course, you would never hit a 7 spot if each quad got 5 or six numbers drawn in each every time. Again, just curious as to why the Casinos I play in have a different rng count. I know I surely will never figure it out but I did play the other day for over 3 1/2 hours with $5.00 on a nickel machine betting .05 per game and had a blast trying to outsmart the computer. Kind of like looking at deer tracks in the woods. The only thing the tracks mean is that a deer WAS there at one time.... Again Thanks.
