1. Types Of Poker Games At Casinos

Land based casinos are a common place to spot players entertaining themselves with Omaha variations. That doesn’t mean they are not present online. They are, they just aren’t as popular as Texas Hold’em Poker. Seven-card Stud. This game is popular in the US and in casinos. When Three Card Poker was invented, there was one available pay table for Pair Plus. You’d get 40-1 on a straight flush, 30-1 on three of a kind, 6-1 on a straight, 4-`1 on a flush and 1-1 on a pair for a house edge of 2.32 percent. That pay table is rare today, both in live casinos and online casinos.

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.

Types Of Poker Games At Casinos

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.

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.

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.

The card game of poker has many variations, most of which were created in the United States in the mid-1900s. The standard order of play applies to most of these games, but to fully specify a poker game requires details about which hand values are used, the number of betting rounds, and exactly what cards are dealt and what other actions are taken between rounds.

• 1Popular poker variants
• 2Specific poker variant games

Popular poker variants[edit]

The three most popular poker variants are spread in casinos and poker rooms worldwide and can be divided into the following groups:

• Draw poker: Games in which players are dealt a complete hand, hidden, and then improve it by replacing cards. The most common of these is five-card draw.
• Stud poker: Games in which each player receives a combination of face-up cards and face-down cards in multiple betting rounds. The most common of these are five-card stud and seven-card stud. These two variants are further played in other different formats.
• Community card poker: Games in which each player's incomplete hidden hand is combined with shared face-up cards. The most common of these are Texas hold 'em and Omaha hold 'em.

Here are more common rule variations:

1. Lowball: The lowest hand wins the pot. There are different rules about whether or not aces count as low, and the effects of straights and flushes. The most common variants are Razz and 2-7 Triple Draw
2. High-low split: the highest and lowest hands split the pot. Generally there is a qualifier for the low hand. For example, the low hand must have 5 cards with ranks of 8 or less. In most high-low games the usual rank of poker hands is observed, so that an unsuited broken straight (7-5-4-3-2) wins low (see Morehead, Official Rules of Card Games). In a variant, based on Lowball, where only the low hand wins, a straight or a flush does not matter for a low hand. So the best low hand is 5-4-3-2-A, suited or not.
3. Players can pass cards to each other. An example of this would be Anaconda.
4. Kill game: When a fixed limit game is played and a player wins two pots in a row, the stakes are doubled. In some split-pot games, a player winning both halves of the pot may also cause a kill. In some variants of Lowball, a player may choose to kill by placing a double bet after seeing his first two cards.
5. Wild cards are added. This can range from simply making deuces wild to the 7-card stud variant named baseball.
6. A twist round in which players can buy another card from the deck. If a player does not like the purchased card, the player can purchase another one by adding money to the pot. This is sometimes called a 'tittle.'
7. A stripped deck may be used. Poker was first played with only 20 cards. In the spirit of poker history, players will sometimes only play with a stripped deck. A popular poker game in Spain is played with cards 8-A. It is played similar to hold'em, except that one card is dealt at a time and a player must use both hole cards.
8. Roll your own is played in stud games, and allows the player to determine which of his or her cards are turned up and visible to the other players. In a game like Seven-card Stud, the 'roll' action only applies to the first 3 cards, all of which are dealt face down. Each player then determines which card to expose. Play then continues as with regular Seven-card Stud. But a game like Mexican stud applies the roll option throughout the game. Two cards are dealt face down, and the players roll one card up. The game continues just as in Five-card Stud, except the cards are dealt face down, and each player then decides which of the two down cards is exposed.^[1]

Mixed poker games[edit]

Poker can be played in a mixed game format, for example one half-hour of Texas hold 'em followed by one half-hour of Seven-card stud. There are many types of mixed poker games. The most notable mixed poker variation is H.O.R.S.E. poker. H.O.R.S.E. is a mix of Texas hold 'em, Omaha high-low, Razz, Seven-card stud and Seven-card stud Eight-or-better. Each game will usually be played for a fixed number of hands or time and then the players will move on to the next game.

Other mixed games include:

• H.O.S.E. – same as H.O.R.S.E., except without Razz.
• H.O.E. – same as H.O.R.S.E, except no Razz or Seven-card stud.
• H.O. – Texas hold 'em and Omaha high-low
• O.E. – Omaha high-low and Seven-card Stud Eight or better.
• H.A. – Pot limit Texas hold 'em and pot limit Omaha.
• Omaha High-low Mixed – Fixed limit Omaha and pot limit Omaha high-low
• Holdem Mixed – Fixed limit and no limit Texas hold 'em.
• Eight Game Mix – Fixed limit 2-7 Triple Draw, fixed limit Texas hold 'em, fixed limit Omaha Hi-Low Eight or better, Razz, fixed limit Seven-card stud, fixed limit Seven-card stud Hi-Low eight or better, no limit Texas hold 'em and pot limit Omaha.
• Ten Game Mix (introduced at 2011 World Series of Poker) – No limit Hold'em, fixed limit Seven-card Razz, fixed limit Hold'em, fixed limit Badugi, fixed limit Seven-card Stud, no limit 2-7 Single Draw, fixed limit Omaha Hi-Low eight or better, pot limit Omaha, fixed limit 2-7 Triple Draw and fixed limit Seven-card stud Hi-Low eight or better (played with 6 players on a table).

Specific poker variant games[edit]

Some poker games don't fit neatly into the above categories, and some have features of more than one of these categories. These variants are most often played in home games, usually as part of a dealer's choice format.

High Chicago or Low Chicago[edit]

Either of these two versions can be played in any stud high game. In High Chicago, or sometimes simply called Chicago, the player with the highest spade face down (referred to as in the hole) receives half the pot. In Low Chicago, the player with the lowest spade in the hole receives half of the pot, with the A♠ being the lowest. If the player with the highest hand also has the highest/lowest spade in the hole, then that player receives the entire pot - having won both sides of the bet.

Follow the Queen[edit]

This 7-card stud game uses a wild-card designated as whichever card is immediately dealt (exposed, or face-up) after any queen previously dealt (exposed). In the event that the final card dealt (exposed) is itself a queen, then all queens are wild. If no queens are dealt (exposed), then there are no wilds for that hand. Betting is the same as in normal 7-card stud games. Follow the Queen is a typical game variant in Dealer's Choice poker games.^[2][3]

Countdown[edit]

In this 5-card game, the dealer gives each player 5 cards face down. After the first round of betting, each player may choose to replace zero to three cards. A second round of betting follows and then players may opt to replace zero to two cards. Upon completing another round of betting, each player may replace one card of the cards in their hand. After a final round of betting, any remaining players show their hands, and the highest 5 card hand wins. The cost of cards doubles each round. For example, if the dealer says each replacement card costs $10 in the first round, then each card costs $20 in the second round, and $40 in the final round. When players purchase cards to replace ones in their hand, they put the cost of the cards in the pot.^[4]

This game will only work with 4 players (or fewer) otherwise you will run out of cards.

Billabong and Shanghai[edit]

Just as Oxford stud is a mixed stud/community card version of Texas hold 'em, Billabong is a mixed version of Manila. Each player is dealt two down-cards and one up-card. Low up-card starts the betting with a Bring-in if you are playing with one, otherwise high card starts the betting. Next, two community cards are dealt, followed by a second betting round, beginning with the player with the best exposed partial poker hand (counting the community cards, as in Oxford stud). Then a third community card is dealt, followed by a third betting round. Finally a fourth community card is dealt, followed by a fourth betting round and showdown. Each player plays the best five-card hand he can make from the three in his hand plus the four on the board in any combination.

Shanghai is the same game with an extra hole card, but no more than two hole cards play. That is, the game begins with each player being dealt three down-cards and one up-card; each player must discard one of his hole cards at some point during the game as determined ahead of time. The most common variation is to discard immediately as in Pineapple; the second most common is to discard just before showdown as in Tahoe.

Guts[edit]

Guts is a family of games that are cousins of poker rather than poker variants. They usually involve hands of 3 or fewer cards, ranked similarly to hands in poker, and multiple successive rounds of betting each of which consist of the decision to be 'in' or 'out', and each with its own showdown. The losers of rounds of guts generally match or double the pot, which grows rapidly.

Five-O poker[edit]

Five-O Poker is a heads-up poker variant in which both players must play five hands of five cards simultaneously. Four of the five cards in each hand are face-up. Once all five hands are down, there is a single round of betting. The winner is determined by matching each hand to the corresponding hand of the opponent. The player with the stronger poker hand in three (or more) out of the five columns, wins, unless a player folds on a bet that was made. If a player beats their opponent with all five hands, this is called a “Five-O” win.

Chinese poker[edit]

Chinese poker is a 2-4 player poker game with thirteen cards. The idea is to make three poker hands with increasing rank : two with five cards and one with three cards. If one of the hands does not adhere to increasing rank (i.e. is mis-set), the hand is declared dead and results in some sort of penalty.

Kuhn poker[edit]

Kuhn poker, using a three card deck, is more of game theory problem than an actual game people play, but it can be played by two players.^[5]
