In early 2017 Arizona passed new legislation banning greyhound racing in the state. All proceeds from Arizona’s tribal casinos are required to be used for charity, or to the benefit of the tribal governments. Native American Tribal lands in Arizona take up more than 20 million acres, that’s more than a quarter of all the land in Arizona. All casino gambling activities are monitored and governed by the Arizona Tribal-State Gaming Compacts, which are agreements between the state of Arizona and 21 separate Native American tribes. Arizona gambling is limited to tribal casinos, horse racing, and the official state lottery. In the 1990’s casinos were legalized in Arizona as long as they were located on Native American reservations.
