Currently, the game is rather dated, and difficult to find....is fading off into the sunset.

If that's the case, I wonder why you bothered. Is it your intention to include as many games as possible, even defunct games (your Faro page comes to mind)? Or was the math just too easy, making the page very simple to create?

Note regarding Faro: That has so much history, that it's inclusion seems to make sense.

It chooses 80? How can ya lose? LOL

Logging all the games that have made it out to the casino floors is kinda of nerdy cool. At some point it becomes a historical archive of gaming. : )

A lot goes into which games I include on the site. This game had in its favor that it IS currently found in Vegas and was easy to analyze. Also, since the Venetian incident, I've had more time on my hands.

Faro is such a historically significant game that I felt I would be remiss in my duties to not address it. Before I wrote that page I was asked about it dozens of times.

Why bother doing a page on Keno to begin with?

I completely agree with the analysis.

It is a rather boring keno game. I really dislike that the diamonds are determined by a secondary decision, unlike Caveman Keno where the bonus is determined by the 20 balls drawn.

Thanks for checking it. I also dislike that the diamonds are not found naturally, but by a process unseen to the player. There is already a law in Nevada that says that video representations of card games may not be gaffed, but every card in the deck must had the same odds. If there were such a law for keno, I would say this game would not be compliant.

I'm unclear on the diamonds probability -- is it 2% per number? 2% overall?

The rules for facsimiles of real games are:
Quote: Reg 14.040

(b) For gaming devices that are representative of live gambling games, the mathematical
probability of a symbol or other element appearing in a game outcome must be equal to the
mathematical probability of that symbol or element occurring in the live gambling game. For other
gaming devices, the mathematical probability of a symbol appearing in a position in any game
outcome must be constant.


I'd say that, due to the diamond feature, this isn't technically a representative of a live gambling game. If the probability of the diamonds is constant (at 2%?) then it's probably okay.

I agree. And I kinda said so in my post.

For the record, I meant to say that it's cool that you would try to include as many games as possible, even defunct games, so you become the one-stop resource.

Overall.

Here is a screenshot from the rules.



The key part is "The game chooses 20 spots, 3 of which may be marked by diamonds." Just playing the game it gives the impression that the diamonds were hidden among the 80 numbers and they are uncovered if the draw lands on them. As in Caveman Keno.

Since keno is a live game, if I were forced to make a ruling, I would say it isn't complaint with 14.040. Then again, I'm not going to complain. The game has been out there 16 years, which may predate that statute. Even if it doesn't, this doesn't seem like something worth fighting over.

Keno may be a live game, but the feature "3 of which may be marked by diamonds" isn't. If the "may be marked by diamonds" probability is constant at 2%, it would seem compliant under the second part of that reg.

I'd equate this to a random bonus feature in a card game like video blackjack, where say with 10% probability if you have the ace of hearts in your hand you get 5x your bet. The cards themselves are representative of a regular deck. You'd need to use a secondary RNG to generate the 10% test but it'd still be okay because the odds of that feature are constant.

You're welcome.

If it were poker, they would simply need to state the frequency in the help screens. Consider Super Times Pay: the multiplier selection is done independently of the cards, but the help screens give enough information to completely analyze the game.

Keno doesn't fall under the same umbrella as poker since there is no player strategy.

The biggest (In my oppinion) skirt of this law is Wheel of Fortune. The wheel has slices appear to be the same size and lead people to think that they are equally likely. It's not exactly representative of a live gambling game, but it's like Roulette or Big 6.

As a side note, every game I've ever seen with a die has a 1 in 6 chance of landing on each side. A die itself is not representative of a live gambling game, unless it is used in something like craps or sic bo.
I heart Crystal Math.

I don't like it either, but the idea of a weighted wheel is well established with the Telneas (sp?) patent.

The equally-spaced stops on weighted 3-reel games are the same way, and there are live-game examples of that too (e.g. the Showcase Showdown wheel on The Price Is Right). I think it's safe to assume that "rotating devices with unequal probabilities of an indicator stopping on equally-spaced segments" are universally accepted by regulators. We're coming up on 30 years since Telnaes.
