If you’ve ever visited a Native American casino, chances are you’ve seen a Class II slot machine. They’re the games that display a bingo card somewhere on the screen.
So what are Class II slots and how are they different from the slot machines you’d find in Las Vegas?
A Brief History
Class II machines are similar to Class III machines, each machine has a pull handle or touch screens and are relatively the same size. Usually Class II machines are for games such as Bingo and other random number generated games of chance. A Class II machine lets a central service determine if you win or lose each hand. The Class II slot machines are designed to replicate Class III slot machines while remaining within the confines of the regulatory guidelines. The Class system is clearly stated and defined in the Indian Gaming Regulatory Act by the Federal Government.
In 1988 the United States enacted the Indian Gaming Regulatory Act (IGRA), establishing the framework governing Native American gaming laws. The act established 3 classes of gaming:
- What are class 2 slot machines anyway? The phrase “class 2 slot machines” is misleading because the classification system is applied to all types of gambling games, not merely slot machines. In 1988 the United States Congress passed the Indian Gaming Regulatory Act.

- Class I: traditional and social games for minimal prizes
- Class II: games of chance based off bingo
- Class III: a catch-all category of games that can’t be considered Class I or II, like slots, roulette, blackjack, etc.

Knowing the hurdles Native American casinos faced to allow Class III slots, gaming companies began developing Class II gaming machines: games that play like regular slots but are technically fancy versions of bingo.
Difference between Class II Games and Regular Slots
Regular (class III) slots use a random number generators (RNG) that generate thousands of random numbers each second. When you hit spin, that RNG locks in the value at that moment. Then the slot assigns reel positions to parts of the random number and evaluates your win (if there is one). We covered this in more detail here.
To be legally considered as such, class II slots have to be based on bingo. This is where class II game developers have been creative, often implementing different approaches. On some, like WMS and Multimedia Games, your machine’s “bingo card” remains constant and the drawn numbers change each time. On others (like VGT), you stay in the same game while your card randomly changes each spin.
The implementation doesn’t especially matter. What matters is that the game has the necessary elements required to be bingo: more than 1 player (class II slots must be networked together) and a set of numbers drawn that must match a pattern to result in a win that ends the game (a game-ending pattern).
The fact is Class II slots still rely on RNG to generate the cards and drawn numbers. It doesn’t matter if the RNG is creating simulated bingo cards/numbers on a class II game or virtual reel positions on a class III slot – the results are still random. Universal slots no deposit bonus codes. Payouts are determined on regular slots by adjusting the reels and likelihood of landing on any position. Payouts on class II slots are defined by specifying the bingo patterns that must be matched and within what number of numbers drawn.
Why NA Casinos Prefer Class II
While many modern NA casinos have a mix of class II and III games, the numbers almost always skew heavily towards class II games. Why?
For one, the IGRA granted tribes the power to self-regulate Class II gaming, whereas tribes have to enter state compacts to offer class III games.
But the big reason NA casinos prefer class II games is that tribes don’t owe taxes on class II revenue like they do on class III games.
Licensed slots and most of the fancy new, popular games aren’t available in class II form, so NA casinos keep a mix. However, slot manufacturers are taking an increased interest in offering Class II games. Aristocrat bought Oklahoma-based bingo game developer VGT and used their technology to start offering some Aristocrat favorites in Class II form.
The Bottom Line on Class II Games
Class 2 Slot Machines Quick Hits
Modern class II games can look, act, sound, and feel like typical class III, Vegas-style slots.
Class II games are sometimes criticized for their mysterious nature, leading some to believe they can be rigged. They’re networked together as a central server determines the wins.
Class III slots go through rigorous third-party and government testing to ensure their randomness and resistance to rigging. Class II slots go through some of the same tests, but the self-regulating nature and lack of transparency of NA casinos have historically raised questions about their fairness.
Though their back-end operates different, both class II and class III games still ultimately rely on RNG. Casinos don’t need to rig the machines because the games’ math is already in their favor. That’s not to say their games’ programmed payout percentage is going to be to your liking, but the notion of some casino worker selectively deciding who’s going to win and lose on class II games is just a myth that doesn’t make sense.

In November 2004, Oklahoma residents approved a State-Tribal Gaming Act through a referendum.

Based on this generic model, 31 tribes negotiated state-tribal compacts with the state of Oklahoma.

Slot Machine Private Ownership in Oklahoma
It is legal to own a slot machine privately in the state of Oklahoma if it is 25 years old or older.
Gaming Control Board in Oklahoma
Oklahoma’s state-tribal compacts regulate tribal gaming in Oklahoma. However, the state of Oklahoma provides oversight under these compacts, which is the legal responsibility of Oklahoma’s Gaming Compliance Unit.
Based on the Oklahoma Gaming Compliance Unit Annual Report 2018, Oklahoma’s casinos prefer offering more Class II games due to Class III games requiring up to an extra 6% of revenue to the state.
The state also collects exclusivity fees from Class III machines. In 2015, 57% of all gaming machines in Oklahoma were Class III games.

Summary of Oklahoma Slot Machine Casino Gambling in 2020
Oklahoma slot machine casino gambling consists of over a hundred tribal facilities with electronic gaming machines existing as casino resorts, casinos, convenience stores, travel centers, bingo halls, and more.
Gaming regulations come from a generic tribal-state compact, used by 31 tribes in Oklahoma to legalize Class II bingo-style and Class III Las Vegas-style gaming. It does not include theoretical payout limits nor require that tribes make return statistics publicly available.
Annual Progress in Oklahoma Slot Machine Casino Gambling
Over the last year, Bordertown Casino and Arena closed when the Eastern Shawnee Tribe decided to reassess its business plans and close the facility in December 2019. Also, the Texoma Gaming Center in Kingston became the Texoma Casino.
In early 2020, Governor Kevin Stitt of the State of Oklahoma demanded the state’s tribes update their tribal-state compacts. At issue was an attempt to improve the state’s gaming revenue by increasing income from exclusivity payments for monopoly casino rights. Ultimately, Oklahoma’s tribes united against the Governor, resolving the “bitter feud.”
