While Nevada is famous globally, the vast majority of physical casino locations in the United States are actually located on tribal lands.
Understanding the history of these venues is crucial for understanding the modern landscape of American gambling.
The Indian Gaming Regulatory Act Explained
The modern era of tribal gaming officially began with the passage of the Indian Gaming Regulatory Act (IGRA) in 1988.
Class III gaming includes full-scale casino gambling (slot machines, blackjack, roulette) and requires the tribe to negotiate a complex 'compact' with the state government.
- These state compacts dictate exactly how much revenue the tribe must share with the local state government in exchange for holding a monopoly
- Because they operate on sovereign land, tribal casinos are generally exempt from many standard state taxes and corporate regulations
- This sovereign status is why a massive, full-scale casino can exist legally in a state where commercial gambling is otherwise strictly prohibited
Class II vs. Class III Machines: The Hidden Difference

The spinning reels on the screen are just an entertaining visual animation; whether you win or lose depends entirely on the hidden digital bingo card.

From the massive Foxwoods Resort in Connecticut to small bingo halls in the Midwest, tribal gaming is incredibly diverse.
