The 10 Biggest Casinos in the US

  • Last Update: January 10, 2025
Winstar World Casino and Resort in Oklahoma.

Las Vegas is regarded as the global home of casinos, so you would expect the largest casino in America to be located in Sin City. However, you may be surprised to see how many super-sized casinos are located outside of Nevada and the bright lights of Vegas.

We have listed America’s biggest casinos according to the square footage of their gaming floors to find you the most immense casino gaming experience. There are so many sites out there with top ten lists using dubious sources, so we created our list based completely upon the information available on the casinos own sites wherever possible. And on this page we are also going to give you a flavor of what each of our colossal casinos has to offer in case you are planning a visit.

WinStar World Casino & Resort, located in Thackerville, Oklahoma, is the largest casino in the United States – and it’s not even close. Opened in 2003 as Winstar Casino, the original version featured bingo rooms and some electronic games in a heavy-duty tent. It’s fair to say that this casino has changed beyond recognition since then! Today it boasts over 8,600 slot machines, more than 100 table games, and a variety of high-stakes rooms spread over ‘nearly 400,000 square feet of gaming floor’. Winstar is one of 20 casinos operated by the Chickasaw Nation, and is of course its flagship property, helping to provide economic support to tribal members. This enormous resort includes a world-class golf club with two courses, luxurious hotel accommodations with over 1,400 rooms, multiple dining options, and a 65,000 square feet event center that hosts concerts, comedy shows, and other entertainment.

We take a trip to the East Coast for the third-placed entry on our list of the largest casinos. Wikipedia says that there are 340,000 square feet of gaming floor at this casino, but the Mohegan Sun website says ‘more than 300,000 square feet’ and we will take that as the most accurate source. That’s not to downplay the sheer scale of this gorgeous casino and resort. The numbers are staggering: over 4,000 slots and 300 gaming tables, two luxury hotels, more than 45 restaurants and bars and three entertainment venues – one of which can seat 10,000 people.

The Biggest Casino in Las Vegas: Wynn Las Vegas & Encore Resort

Gaming Floor Size191,424 sq. ft.
Slot Machines~2,000
Table Games240+
Date of ConstructionApril 28, 2005 (Wynn), December 22, 2008 (Encore)

We couldn’t complete this list without mentioning the biggest casino in Las Vegas, even if it doesn’t quite make it into our top ten biggest in the country. Unsurprisingly, Nevada has the most casinos of any US state – around 345 – but none of those are big enough to break into our top ten. For anyone who’s counting, Montana ranks second with over 170 casinos, and Louisiana and Oklahoma have 136 and 109 casinos respectively. The Wynn/Encore combination isn’t too far away when it comes to size though, and together they have the largest gaming floor in Las Vegas at just short of 200,000 square feet. The Wynn/Encore beats out the MGM Grand for the honor of Vegas’ biggest casino as between the two hotels the total gaming space adds an extra 20,000 square feet to what the Grand can offer.
