Desert Diamond Casino Tucson is the Tohono O'odham Nation's property on the Nogales highway south of the city. It rates 4.1 from more than 9,800 Google reviewers.
At 165,000 square feet it is one of the largest gaming buildings in Arizona — bigger in floor area than several properties with far more machines, which tells you something about how the space is used.
What's on the floor
More than 1,000 slot machines, table games, a poker room and self-service sports betting kiosks.
Blackjack runs 24 hours a day, which is not true of every Arizona pit and is the most useful single fact about the table offering here. Three Card Poker sits alongside it.
The bingo room seats 300 with both smoking and non-smoking sections, and runs progressive jackpots on several games. One practical detail worth planning around: bingo is closed on Tuesdays and Wednesdays. If bingo is the reason for your trip, do not drive down midweek.
Dining
Six outlets. The Agave Restaurant is the fine-dining room; the Diamond Grill and Diamond Café cover the middle; the Ko:Sin Ki: Buffet handles volume; there is a coffee bar, and two lounges sit on the gaming floor itself.
Hotel and conference space
The attached Hotel and Conference Center carries meeting space alongside the rooms, with a heated outdoor pool, a jetted hydro-spa, patio seating around a fire pit, and a fitness centre.
The outdoor spaces are the point in southern Arizona — a fire pit and a heated pool make winter evenings usable in a way they are not further north.
Tips before you go
You must be 21 to gamble. That comes from Arizona's tribal-state gaming compacts and applies at every tribal casino in the state.
The casino is open 24 hours, seven days a week. The bingo room is not — closed Tuesdays and Wednesdays.
The Nation operates several properties across southern and central Arizona under the Desert Diamond name, and they are easy to mix up. This is the Tucson one, south of the city on the Nogales highway — distinct from the Sahuarita property further south and from the Phoenix-area floors.
Nearby alternatives
South, Desert Diamond Casino Sahuarita is the Nation's other southern Arizona floor. West in Tucson, Casino del Sol is the Pascua Yaqui resort with a hotel, poker room and golf course, and Casino of the Sun is its small original casino with $3 blackjack.
