Gaming on this stretch of desert belongs to a nation whose lands cover 2.8 million acres - the second-largest tribal land base in the United States. Desert Diamond Casino at 1100 West Pima Mine Road, off Interstate 19 in Sahuarita south of Tucson, opened in 2002 as the flagship expansion of the Tohono O'odham Nation's gaming enterprise. The Nation's modern gaming history began with Papago Bingo in 1983; its first compact with Arizona in 1993 turned that hall into the original Desert Diamond Casino, and in 2002 the Nation led the campaign for Proposition 202, the ballot measure that set the framework for Indian gaming across the state - the same year the Pima Mine Road property opened its doors. The casino runs the full Arizona complement: slot floors, table games, poker and bingo, wrapped with restaurants and bars in a complex that anchors the southern end of the Tucson metro's entertainment map. It operates alongside the Nation's other Desert Diamond properties in Tucson, Why, Glendale and the newest White Tanks casino, making the enterprise one of the largest tribal gaming operations in the Southwest. The Diamond Center is the entertainment jewel - a 2,000-seat indoor concert venue whose sightlines the operators market with a simple promise: every seat is the best in the house. Its stage has carried national country, rock, Latin and comedy tours, waila music celebrations honouring the Nation's own social-dance tradition, boxing cards and community events. The venue went dark with the pandemic in March 2020 and stayed closed longer than any of its Tucson peers - a decision the Nation attributed to community safety protocols - before comedian Ron White relaunched live entertainment in September 2022, and the concert calendar has rebuilt steadily since. For travellers on the I-19 corridor between Tucson and Nogales, the casino is the region's single biggest night-out destination - gaming, dining and arena-calibre touring acts twenty minutes from downtown Tucson, on sovereign land whose gaming revenue funds the Nation's services.
