Under US federal law, gambling is legal in the United States, and states are free to regulate or prohibit the practice. Gambling has been legal in Nevada since 1931, forming the backbone of the state's economy, and the city of Las Vegas is perhaps the best known gambling destination in the world. In 1976, gambling was legalized in Atlantic City, New Jersey, and in 1990, it was legalized in Tunica, Mississippi; both of those casino spielen cities have developed extensive casino and resort areas since then. Since a favorable U.S. Supreme Court decision in 1987, many Native American tribes have built their own casinos on tribal lands as a way to provide revenue for the tribe. Because the tribes are considered sovereign nations, they are often exempt from state laws restricting gambling, and are instead regulated under federal law. Additionally, almost all states have legalized gambling in the form of a state-run lottery and most states allow for limited non-profit organizations to host Bingo nights.
