Santan Mountain is the newest of the Gila River Indian Community's casinos and the best-rated: 4.3 from around 2,900 Google reviewers. It opened over the weekend of 30 June and 1 July 2023, a $180 million development on a 160-acre site in Chandler, after breaking ground in October 2021.
That recent opening explains a quirk in the data — the property is searched for heavily but has a modest review count, because three years is not long enough to accumulate one.
What's on the floor
Roughly 900 slot machines including a dedicated high-limit bank, and a live table pit that is unusually deep for a new floor: 15 blackjack tables, three Ultimate Texas Hold'em tables, three-card poker, two craps tables and three roulette wheels.
One of those wheels is worth the trip on its own. Santan Mountain installed the first white roulette wheel in America — a cosmetic thing, but a genuinely novel one, and the detail people mention most in reviews.
There is a separate electronic table games area carrying electronic roulette, craps and video poker, and a luxurious High Limit Room.
The sportsbook
The BetMGM Sportsbook here is the largest casino sportsbook in Arizona. For a state that legalised sports betting relatively recently, that makes Santan Mountain the default retail betting destination in the south-east valley, and it fills accordingly on NFL Sundays.
Dining
A three-concept casual dining area covers the quick end, with a sit-down restaurant pitched as high-end but approachable above it.
The styling throughout is modern in a way the older Gila River floors are not — this was built in the 2020s and looks it.
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.
There is no hotel here. For accommodation under the same operator, Wild Horse Pass Hotel & Casino and Vee Quiva Hotel & Casino both have rooms.
The Gila River Community now runs four casinos in the metro, and they are easy to confuse. This one is at Gilbert Road and Hunt Highway in south Chandler — a different site from Lone Butte and Wild Horse Pass, both also in Chandler.
Nearby alternatives
Also in Chandler, Lone Butte Casino has a 30-table poker room with its own entrance, and Wild Horse Pass Hotel & Casino is the resort property. North in Scottsdale, Talking Stick Resort is the largest floor in Arizona.
