Sep 08, 2017  On how the machine works: Class 3 uses Random Number Generators and class 2 uses a server that controls how much a person wins. So, while class 3 outputs are random, class 2 are not. Each payoff in class 3 is against the odds of the winning hand. In slot 2, odds are not random, but they are server generated. Jul 27, 2012  Regardless of their technological advancement since the 1930’s, slot machines are still categorized into two groups: class II or class III. Class II Slot Machines. All machines or terminals are linked together so that players end up competing against each other for a common prize.

I am a frequent player at Casino Arizona Talking Stick Resort. I have been playing slots @TSR for about a year. I did well during 4th quarter of '14. I starter to almost recognize a for sure losing machine pretty quickly. Sadly, can not recognize the winners at all =)
This casinos slots seem to be pretty 'tight' and love to 'tease'. I have read so much about slots in the last year that i keep playing at TSR KNOWING it is just luck.... until i came across(10minutes ago) an article that talks of class 2 slots not being so random! Which would make a lot of sense why i just witnessed a woman drop 5500.00 on a .50 keno machine and won less than 100.
HOW CAN I DETERMINE if my casino is using class 2 or class 3 or a combination of both? Who do i ask? What do i look for?

I would ask at the rewards center/player's club. They should tell you (they tell me when I ask in a new state/jurisdiction). It's usually not up to the casino; it's up to the state or other regulatory authority's compact with the state. This is a good article on how it works in general; it's a federal law that governs the terms of what the NA casinos are allowed to offer and what the states have to let them do, but it's still negotiated state by state. The rule of thumb is, if a class of gaming is allowed anywhere in the state for any purpose, the NA casinos can offer the same class of games. Class II are player-banked, with the casino taking some kind of rake. Class III allows casinos to offer house-banked games. That's just a very simple explanation, but the Class is considered public information, so they should tell you if you ask.
Edit: This is a gov't-issued blank compact application that defines and includes Class I, II, and III gaming for the state of AZ, so I guess it depends on what level the tribe wants to offer/qualify for there.
teddys did a pretty good review on Phoenix-area casinos, and specifically mentioned that they can offer Class II and Class III gaming (though no true craps or roulette). Doesn't mean the Talking Stick doesn't have a mix of II and III slots, but it's a start to know that much.
It's been my experience that Class II slots MUST in some way display a link or reference to the bingo game they're based on, even if it's a really small icon or something. The machine probably shows it somewhere in the instructions/pays button as well (that most people don't use).

I agree. A class II slot should have a little bingo card in the corner of the screen. Often there is a button that says 'daub' instead of 'spin.' If you have any doubt, it is probably class III.

What do i look for?

Does the 'play' button say 'play', or 'play/daub'?

Difference Between Class 2 And 3 Slot Machines

If you scroll through all (and I do mean ALL) the help and paytable displays, does it list a bingo paytable?
Does the front of the place mention that it's a 'Class II gaming facility'?

Slot Strategies That Work

Does the machine have a display of a bingo card on it? (Sometimes - particularly on the 'keno' machines, it's mostly hidden - I've seen it on the topmost video screen, up by the slot-topper blinking light sign)
Is there a sticker on the machine that says (something like) 'Prizes awarded based on bingo play'?
... so then, it might be Class III.
... And ask at the player's club booth if they have any Class II machines, and how you'd tell the difference.
I've played both Class III and Class II machines; they're both vaguely similar in that you stick money in, whack the button, and maybe get some money back. My subjective observations say that Class II behaves quite differently as the number of other players changes; sometimes better, sometimes not.

In fact, the Pima-Maricopa Indian Community (see pages 24 & 25) had, perhaps, the hardest battle to finally get a compact. It spanned multiple lawsuits, a general election initiative (Pima-Maricopa was successful) and then even more lawsuits over a ridiculous span of three years. I'm sure there was a reason that Arizona made it so difficult for this tribe, but don't care enough to look further into it, and ultimately, the reason must have been ridiculous because the State was eventually forced to negotiate a compact with them.

Maybe Az. didn't want competition for their scratch off tickets?
Could be Zcore knows something about this?
Thanks for putting this info out, I am going to be in the Phoenix area in the next few weeks.

l i came across(10minutes ago) an article that talks of class 2 slots not being so random!

that exclamation point suggests the article would have you believe class 2 is better. That is the opposite of the usual opinion, so I would take what it says with a grain of salt.
I suppose it is possible there are times, depending on number of players, when class II treats you as well or even better. The one thing you can say for sure is that it is idiotic to think you are playing a game of skill like video poker only to realize you are playing on a class II. Players dislike that for sure.

I wouldn't mind seeing that article if it is a link you can post.

As far as I know every slot in Casino Arizona is Class III. Same as at my Casino. The Compact does allow for some minimal use of Class II slots, but I don't know of any Tribe that is using them.

If you are looking for a better gamble and would like to get comps I would highly recommend you keep driving east of Talking Stick to Fort Mcdowell, the games are much looser and they are far more generous with comps.

Understanding the differences between these two types of games

By Henry Tamburin

I’ve received a lot of questions about video poker machines in casinos on Native American reservations. To get the answers on how these machines work, I interviewed Jim Coleman, Senior Product Manager at IGT (a company that manufactures the majority of video poker machines for Class III casinos).

Before I begin, let me give you a brief history lesson on how Class I, II, and III gaming came about. The federal Indian Gaming Regulatory Act established the three classes in 1988, which defined what Indian tribes in a given jurisdiction can and can’t offer in their casinos. “Class I gaming” is defined as “traditional Indian gaming and social gaming for minimal prizes.” Since Class I doesn’t involve commercial gambling, I’ll ignore it for this article. “Class II gaming” means the game of chance commonly known as bingo, whether or not electronic, computer, or other technologic aids are used in connection therewith, including, if played in the same location, pull-tabs, lotto, punch boards, tip jars and other games similar to bingo, as well as various non-house-banked card games (but for this article, we’ll ignore these other types).

“Class III gaming” is full-scale gambling (e.g., Las Vegas or Atlantic City), including table games (blackjack, craps, etc.), slots, and video poker. Tribes must negotiate compacts with the states to conduct Class III gaming; otherwise, they are limited to Class II gaming, providing bingo is offered in other forms or venues in that state.

The following table summarizes the major differences between a Class II and Class III video poker machine. I’ll explain the information in each row in more detail so you can fully understand the differences.

Class II	Class III
How the final outcome is determined	Result of a winning pattern from an electronic bingo game	Result of a random selection of cards by a random number generator
How the odds are determined	Odds of hitting a certain pattern on a bingo card	Odds of randomly drawing cards from a 52-card deck
Does playing strategy matter?	No. Results are predetermined by the pattern of the bingo game. Nothing the player does on the draw will change the outcome.	Playing strategy can influence the final outcome. Players can achieve theoretical returns for any game by playing their hands perfectly.
Can a player determine the Expected Return of the game from the paytable?	No.	Yes.
How do you know the machine is Class II or III	Look for the small display of a bingo card on the machine	If you don’t see a bingo card, it’s probably Class III

How the Outcome is Determined

A Class III video poker machine has a Random Number Generator (RNG) software program that randomly selects cards from a virtual 52-card deck (assuming no wild cards). When you press the deal button, the RNG selects five cards at random, which is the initial five cards that you see on your screen. The RNG continues to shuffle the remaining 47-card deck until you decide which cards you want to hold. When you hit the draw button, the shuffling stops and the replacement cards are selected from the top of the shuffled 47 cards. By law, each card has to have the same probability of being selected on the deal and draw; therefore, the probability of selecting any card is the same as it would be if you randomly drew cards from a freshly shuffled deck of cards. The probability of getting a winning hand by this random selection process is well known (e.g., the probability of getting a royal flush is roughly once in 40,000 hands).

A video poker hand in a Class II video poker machine is not the result of an RNG outcome at the terminal level. Instead, the machine is connected to a central computer server whose function is to draw bingo balls (randomly as with an RNG.) The result of the bingo game is a “game-ending pattern.” This is a pattern of numbers on a bingo card, such as five-in-row, four corners, round robin, etc., that ends the bingo game with a winning result and a prize. There is a specific timeframe (e.g., 20 milliseconds) in which a player who hits the start button on a bingo machine with a poker entertaining display (i.e., the deal button on his video poker machine) is entered into an electronic bingo game for that common ball draw. Each player has their own bingo card, which they can see on the interface of their player terminal (see photo of display below). The player that has the winning bingo pattern will win a monetary prize.

In addition, other patterns may award interim prizes for the corresponding bingo patterns. For example, the game of Jacks or Better has nine winning patterns (corresponding to the nine winning hands in Jacks or Better). If the winning bingo pattern results in a prize for the bingo game of, say 10 credits, then the player will end up with a poker hand that is presented as two pair on the entertaining display (which is the payout for two pair with max credits wagered).

A key point: Class II player terminals using a video poker entertaining display must involve player participation in an electronic bingo game. Therefore, you must be playing bingo against one (or more) players. You could be playing against other players playing on a video poker entertaining display or even other terminals with varying entertaining displays such as spinning reels (i.e., slot machine).

It really doesn’t matter what the player interface terminal is that will display the results of a bingo game (for video poker, it’s cards on a screen; for other entertaining displays, such as a slot machine, it’s spinning reels). If you happen to be the only player in a location, you can’t play (if you try, a message will appear on your screen, stating “waiting for more players”). However, in some gaming jurisdictions, Class II machines in one location could be linked to another Class II bingo server in another location, so it’s possible you could be playing a game of bingo against a player in a different location using a common ball draw.

Odds

In a Class II terminal using a video poker player interface, the odds of getting a winning hand are determined by the odds of the bingo pattern. Mathematicians at IGT can calculate the odds for millions of different bingo patterns on a bingo card. Therefore, theoretically, they can choose a bingo pattern that mimics the odds of getting any winning hand from a RNG in a Class III machine.

For a Class III video poker machine, the odds of selecting the winning hands from a 52-card deck can be accurately calculated. If you multiply the odds times the payout for each winning hand and sum the results, you can compute the Expected Return (ER) for the game. The ER for different video poker games and pay tables is readily available.

Playing Strategy

If you are playing a video poker machine where the cards are randomly selected by the RNG (e.g., Class III), the skill of the player can influence the outcome.

Class 2 Slot Machine Tips

In a Class II terminal using a video poker interface, playing skill is futile because the result of your hand is already predetermined by the pattern of the winning bingo game. Therefore, deciding what cards to hold prior to hitting the draw button does nothing to improve your chances of winning. For the game of bingo, the result of the bingo game is a certain prize (i.e., payout), and you must get that prize in your video poker entertaining display outcome even if you make a “bonehead play.” For example, suppose you are dealt the following hand:

Let’s say the result of the bingo pattern is a prize of 4000 credits, which translates to a typical royal flush in video poker. However, on the draw, if you decide (knowingly or unknowingly) to hold all the cards instead of going for the royal flush, fear not. A genie will appear on the IGT entertaining display and change the 9 of spades to a 10 of clubs, giving you a royal flush hand and corresponding 4000-coin payout. (The latter payout was determined as the winning outcome of the bingo game.)

Some folks might think the “Genie” feature on Class II video poker machines is good for novice players because it will correct a playing mistake and show them the optimum strategy (i.e., the winning hand created by the “Genie”). Personally, I think this is an expensive way to learn the playing strategy for a video poker game. (It’s better to learn the playing strategy at home on your computer using video poker training software, and then bring a strategy card with you when you play a Class III version.)

Expected Return

Players can look at the Pay Table for any Class III video poker game and know what the ER is for the game (there is plenty of information available that lists the ER for different video poker games). However, on a Class II machine, you have no idea what the ER is for the game (that’s because the results are predetermined based on the game of bingo).

In addition, keep this point in mind. In many states, traditional casinos must report their return percentages to state gaming agencies and this information is often reported to the public. Since Native American tribes are a sovereign nation, their casinos are not subject to state regulation or public reporting of the return percentages on their machines.

Is it a Class II or III Machine?

You’ll know if the video poker machine you are about to play is a Class II machine if you see a display of a bingo card (such as the one below) on your video poker machine.

The Bottom Line

Class II video poker machines are bingo games that give players an entertaining display of video poker that they can relate to. There is no skill involved in playing them and the return on the game is unknown to players. Play these machines for entertainment. Class III video poker machines are a skill-based casino game where the skill of the player can influence the outcome. With a Class III video poker machine, it’s relatively easy to determine the ER of the game.
