While Nevada is famous globally, the vast majority of physical casino locations in the United States are actually located on tribal lands.

The existence of these massive tribal resorts is the result of decades of complex legal battles and federal legislation.

How Tribal Casinos Became Legal

The primary goal of the IGRA was to promote tribal economic development, self-sufficiency, and strong local governments.

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

Why Tribal Slot Machines Sometimes Feel Different

A common complaint from tourists is that the slot machines in certain tribal casinos feel 'weird' or behave unexpectedly.

In a true Class III Vegas slot machine, an internal Random Number Generator determines the outcome of your spin the exact millisecond you press the button.

The next time you play at a tribal resort, take a moment to appreciate the complex legal history that built the building.
