In 1988, the United States Congress passed the Indian Gaming Regulatory Act (IGRA), which allowed federally recognized tribes to establish casinos on tribal property. Under the act, tribes are limited to offer casino games that correspond to the existing level of gaming allowed under state law. North Carolina was unique in permitting the Cherokee to establish a casino offering Class III gaming in 1994, well before the state allowed a lottery. The typical pattern has been for states to offer a lottery, followed by an agreement between the state and the Indian tribe to allow establishment of a casino or other form of gaming operation.
