Good evening all. I have a question about video Keno odds. At Harrahs Cherokee my wife has won 3 video keno jackpots since January, 2 on 8 numbers ans 1 on 10 numbers. I'm really curious about the odds. I'n not really a gambler and don't know odds but would that be rare? I think it is but don't really know. A lot of her play is video poker, maybe a third keno. Thanks for satisfying my curiosity.

yes.

when you say jackpots.. I'm assuming you mean all 8 numbers and all 10 numbers. If you mean something less, you need to specify how many they hit.

Odds of winning 8 of 8 are approximately 230,113 to 1
Odds of winng 10 of 10 are approximately 8,911,710 to 1

Extremely rare on the 10-Spot, especially given the number of plays she has likely put in during that amount of time. It also depends on whether she hit 10/10 for a Jackpot or some other number out of ten as well as how frequently she plays and how much she was betting. You can get a handpay on 7/10 if you're betting high enough on many Keno games, and that happens about once in just over 600 plays.

I could give you a reasonable approximation of the probability of her running this well, but need much more information. Game, Paytable, Frequency She Plays, Amount Bet, what the hit actually was...

It was 8 out of 8 and 10 out of 10. She was playing \$1.00 which awards the jackpot if you get all 8 or 10 numbers.

Are these the Pot o Gold keno machines that litter Cherokee? If so, are you sure the one you are playing uses a true random number generator and isn't a pull tab? The older models used in gas stations in GA, SC and NC could use a chip that altered the outcome which has always made me a bit suspect of the ones in Cherokee.

I assume that means that if you play enough numbers, you don't have to hit all of them to get to the game's maximum payout.

I didn't know it was 10/10 at the time. Depending on amount bet, anything from 7-9 out of 10 could or could not be a jackpot.

Is the game Super Double up with a variation of Toucheasy or Superball? Like it drops 10 balls and asks you if you want to double your bet? If so, that is a Pot of Gold, the same machines that spread Shamrock 7's.

There is a chip that was used by the gray area video poker parlors years ago that lowered their variance (or sometimes the payout below what was displayed on the screen) by turning them into pull tabs. That means they were set to pay a certain amount after a hold, not use a true RNG to determine numbers drawn. This way the operator would never run massively negative due to variance for their poorly bankrolled operations.

If Cherokee uses the same chips that were all over the Carolinas, Georgia, and Alabama, then the machines aren't legit. Math is not relevant to them because the machine simply determined it was time to pay and threw up the numbers needed to make the jackpot.

Those machines can work with true RNG or pull tab, depending on the card and what the operator chooses to use. That is why you don't see them in commercial casinos. They can be rigged so to speak. A machine that can be tampered with in that way doesn't comply with NV gaming regulations or any other state that uses them.

I'm not saying Cherokee uses these or has ever used these chips, or that the newer version operates this way. My question was simply are you sure that they are not using one of those chips.

There is a single deck blackjack game on these machines at Cherokee that is S17, D 9-11 that also allows players to hit split aces and get a six-card charlie. The player also wins if the dealer makes a six-card charlie. Those rules would make the game return over 100% and takes a players card, something that has always made me concerned about how it operates. They've had those games for a decade. You'd think the AP's would have destroyed them by now with the \$50 max bet.
