Native Americans are usually allowed to operate casinos and bingo halls on Indian reservations. The main reason is that Native American gambling laws are a little bit more special than the United States Gambling Laws which apply to the rest of the society. Native American casinos in the United States are operated in 28 states.
Native American gaming comprises casinos, bingo halls, and other gambling operations on Indian reservations or other tribal land in the United States. Because these areas have tribal sovereignty, states have limited ability to forbid gambling there, as codified by the Indian Gaming Regulatory Act of 1988.
