Top 10 Biggest Casinos In The US | Size By Square Feet

America boasts some of the most outstanding casinos in the world. Whether you’re on the Texas-Oklahoma border, where everything bigger is better, or visiting the opulent tribal casinos in Connecticut, the biggest casinos in the US are more than just a place to gamble; they are a place to make all your dreams come true.

Join us as we take a look at the top 10 biggest casinos in the US.

1. Winstar: Thackerville, Oklahoma (600,000 Square feet)

Words like stupendously large just don’t convey the immenseness that is the Winstar Casino. Located just minutes from the Texas border, Winstar isn’t just the largest casino in America, it’s the largest casino in the world.

With 600,000 square feet of gaming space, almost 9,000 slot machines, and over 150 table games, the Chickasaw Nation has built a phenomenal mousetrap for the 7.5 million people in the Dallas Fort Worth metro area.

Like all of the mega-casinos on our list, they’ve made gambling the star attraction, but you shouldn’t overlook the world-class golf, spa, top-of-the-line concerts, and luxury dining and hotel experiences.

2. Mohegan Sun: Uncasville, Connecticut (364,000 square feet)

Huge casinos need a constant stream of players to continue to thrive. When the tribes began negotiating gaming compacts in Connecticut 30 years ago, it was obvious from the outset that, with more than twenty million people within a two-hour drive, these casinos would need to be big.

With 364,000 square feet of gaming, Mohegan Sun did not disappoint.

Mohegan Sun boasts 6,400 slots, over 350 table games, a state-of-the-art sportsbook, and stadium betting on baccarat and roulette.

The tribe didn’t scrimp on amenities, with hiking trails, golf, tennis, pickleball, and lots of other fun outdoor activities on offer. There are also countless restaurants and more than 1,500 hotel rooms to meet your needs.

3. Foxwoods Casino Resort: Ledyard, Connecticut (340,000 square feet)

Foxwoods is sort of the bookend to the Mohegan Sun property in that they are similar in their massive gaming square footage but only 13 miles apart.

The Mashantucket Pequot tribe has about 340,000 square feet of gaming space spread across six casinos within a casino. These are comprised of about 5,500 slots and 260 table games.

Foxwoods is also known for its state-of-the-art shopping experience, with almost 100 high-end luxury shops on the property.

In addition to the 2,500 hotel rooms and the usual amenities like golf, the resort offers premier zip-lining and go-carting experiences that draw risk-takers of all ages.

4. Yaamava Resort and Casino: Highland, California (290,000 square feet)

Run by the San Manual band of Indians, the Yaamava casino story is one of almost constant growth and rebirth in the 40 years since it opened.

The casino currently boasts 290,000 square feet of gaming space, with more than 4,400 slot machines and 150 table games. While it only has 400 hotel rooms on the property, the nearby towns of San Bernadino or even Riverside have many overnight stay options.

Other recent additions include a world-class 3,000-seat concert venue, which draws many LA-based bands when they are not on tour, along with a half dozen restaurants and some high-end retailers.

While this resort doesn’t yet offer the amenities that many other properties with similar-sized gaming spaces do, it is in the heart of the Los Angeles metro area and a whole lot closer than the 4-hour trip to Vegas.

5. Thunder Valley Casino: Lincoln, California (250,000 square feet)

This large American casino is operated in Northern California in a joint effort between the Miwuk and Maidu Indian tribes. It is located near Sacramento, California. The 250,000 square feet of gaming space is jampacked with 3,500 slots and 150 table games. 

The hotel only has 400 rooms, and though there is a spa and entertainment venue that holds over 4,000 guests, the spotlight here is more on local play than driving tourist visits.

That being said, it is a beautiful property with plenty of dining options, and just about any game or slot you might wish to play.

6. Hard Rock Tampa: Tampa, Florida (240,000 square feet)

The Hard Rock Tampa, on the other hand, is a true destination resort in the sun. Three pool areas total over 200,000 gallons of water, and one pool area alone has 60,000 square feet of swimming space. 700 lounge chairs, almost two dozen cabanas, and two DJ booth setups round out the poolside attractions.

You can choose from almost 900 hotel rooms and more than a dozen dining options, as well as hit their award-winning spa or top-tier concert tours. That’s before you try your luck at one of their 6,000 slots and 200 table games spread across a well-thought-out casino space of 240,000 square feet.

The Seminole Tribe bought out Hard Rock International at a bargain basement price in 2007, and now have cafes in more than 70 countries, an exclusive brand name to build on, and casino resorts in almost another dozen locations.

This means that your Unity tier card not only works in Tampa, but Atlantic City, and all the other Hard Rock locations, as well as the Mirage. That’s a big deal to people who like to use their tier points and comp credits at more than just one location, and gives the Seminoles the ability to cross-sell to various locations.

7. River Wind Casino: Norman, Oklahoma (219,000 square feet)

The metro area of Norman, Oklahoma, is home to a surprising 1.4 million people, and the Chickasaw-owned River Winds Casino is there to meet all their gaming needs.

It has 2,700 slots, over 20 table games, and a 17-table poker room. Unlike some of the Tribal Casinos located a bit closer to the Dallas—Fort Worth area, the RiverWinds, despite its still very impressive 219,00 square feet of gaming space, is not a mega-resort. In fact, it only has 100 hotel rooms.

They do have partnerships with Panda Express, Burger King, and perennial favorite IHOP for a quick bite, or a buffet and a British Fish and Chips place for something a bit more upscale. Other amenities include a 1500-seat theater, and a gift shop located conveniently near the exit.

8. Choctaw Casino: Durant, Oklahoma (219,000 square feet)

In its 219,000 square feet of gaming space, Choctaw Casino currently has over 7,000 slots, 120 tables, and a large poker room.

Being several hours from the Dallas-Fort Worth area and less than 30 minutes from the largest casino in the US (Winstar), this resort has taken a different look at amenities, creating not one but two huge nightclub/live concert venues, including a Gilley’s Road House.

You can also find over 20 restaurants, ranging from fine dining at Salt and Stone to Texas barbeque, which you’ll need to eat with your fingers.

You will find more than 1,700 hotel rooms, including Vegas-style suites, as well as amenities seldom seen at big US casinos like horse riding, fishing, bowling, hiking, and, of course, a world-class spa to relax in.

9. River Spirit Casino: Tulsa, Oklahoma (212,000 square feet)

Situated in the northeast corner of Oklahoma, the River Spirit Casino is near Tulsa, which boasts about 1 million people in its metro area. It can also draw people in from Kansas and Missouri who are looking for some casino excitement. 

The Muskogee Tribe has 3,100 slots and about 70 table games in their 212,000 square feet of gaming space. 

The tribe has added 483 luxury hotel rooms so far and is making plans for more. Their concert venue can host 2,500 guests and their restaurant choices number over a dozen. The amenity list includes a pool, and convention center.

10. Encore Casino: Boston, Massachusetts (210,000 square feet)

Strictly speaking, this casino, owned by the Wynn group, is located in Everett, MA, and is the only non-tribal casino to make our list of the 10 biggest casinos in the USA.

At approximately 210,00 square feet of gaming space, it is still a massive space filled with 3,400 slots and over 160 table games. This integrated mega resort cost 2.6 billion to build in 2019.

Developed on just 34 acres, this casino doesn’t feature many outdoor amenities due to space constraints, but it makes up for that in 5-star luxury that one would expect from any Wynn property.

The 671 hotel rooms are all lavishly appointed and designed to meet the needs of very discerning clients. There are thirteen restaurants and the entire property is almost a museum space as it is filled with millions in paintings and sculptures.

A Round Up Of The Largest Casinos In America:

1. Winstar: Thackerville, Oklahoma (600,000 Square feet)
2. Mohegan Sun: Uncasville, Connecticut (364,000 square feet)
3. Foxwoods Casino Resort: Ledyard, Connecticut (340,000 square feet)
4. Yaamava Resort and Casino: Highland, California (290,000 square feet)
5. Thunder Valley Casino: Lincoln, California (250,000 square feet)
6. Hard Rock Tampa: Tampa, Florida (240,000 square feet)
7. River Wind Casino: Norman, Oklahoma (219,000 square feet)
8. Choctaw Casino: Durant, Oklahoma (219,000 square feet)
9. River Spirit Casino: Tulsa, Oklahoma (212,000 square feet)
10. Encore Casino: Boston, Massachusetts (210,000 square feet)

There are more than 1,000 casinos in the US, so it takes a true behemoth to make the biggest casino in America shortlist.

With all of the casinos constantly expanding, this list may look very different in a few years, especially as new gaming legislation is passed in states like New York, where the population within a few hours’ drive is easily in the tens of millions.

Perhaps, despite the intense competition in Las Vegas, someone will finally build a mega-resort that puts Sin City back on the top ten biggest list again. Combining the Wynn and Encore properties in Las Vegas only gets us to 195,000 square feet of gaming, so still a little room for improvement.

While bigger isn’t always better, these casinos show the true diversity of gambling in America. From slot halls to five-star luxury, they cover the gamut of the American gambling experience and showcase the reach of gaming growth over the past several decades.

From Norman Oklahoma to Boston, from Riverdale California to Tampa, casinos continue to thrive.
