Foxwoods is the 2nd Biggest Casino in the United States

By Steve Beauregard

In a country with over a thousand casinos, and tens of billions in annual gaming revenue, ten resorts stand tall as the biggest casinos in the United States.

Here, we’re counting square footage devoted to gambling. Some resorts have large meeting rooms, arenas and shopping districts, however that space doesn’t count in the rankings. We’re only ranking these in terms of actual, casino floor space.

That being the case, the largest casino in the U.S. is the WinStar World Casino Resort in Thackerville, Oklahoma.

The massive resort just north of the Texas border has over a half a million square feet of gaming space. It’s not the largest in the world by square feet, however if measuring by number of gaming machines, (slot machines, video poker, video Keno, etc.), WinStar claims that their 7,400 gaming machines make it the biggest casino in the world.

Second on the list of top ten largest casinos in the U.S. is the giant Foxwoods Resort complex in southeast Connecticut, with 344,000 square feet of casino space, 4,800 slot machines, and 280 table games (including poker tables).

Interestingly, Foxwoods used to have 6,300 gaming machines and 380 table games before downsizing due to the recession, and to free up space for more bars, clubs and restaurants.

Largest Casinos in the U.S.

Here’s a list of some of the biggest casinos in the United States, (by floor space dedicated to gambling space, and not overall size of the hotel and resort).

The Mohegan Sun is the 3rd largest casino in the U.S.

Please note that I’ve spent hours trying to find a definitive top ten list, however many Indian casinos do not publish, (or maybe do not know?) their gaming square footage. Unlike commercial casinos in Nevada, where gaming floor space size is a matter of public record, there is less transparency with Indian casinos.

Very large casinos that would normally make the list have been omitted in cases where I could not reasonably verify the square footage of actual gaming space.

So here’s the list of top ten biggest casinos in the United States, along with other notables, and others where reportable square footage data could not be found.

1) WinStar World Casino and Resort – Thackerville, Oklahoma. 519,000 Square feet. 7,400 gaming machines. 97 table games.

2) Foxwoods Resort Casino – Mashantucket, Connecticut. 344,000 square feet. 4,369 gaming machines. 280 table games.

3) Mohegan Sun – Uncasville, Connecticut. 300,000 square feet. 5,087 slot machines and 297 table games.

(Per its website, the Mohegan Sun has “more than 300,000 square feet of gaming…” Interestingly, adding up the advertised square footage of all three of the Mohegan Sun casinos under one roof: Casino of the Earth, Sky and Wind, gives us a total square footage of 344,000 – the exact same as its Indian cousin ten miles to the east. Coincidence?)

4) River Spirit Casino – Tulsa, Oklahoma: 250,000 square feet of gaming space. “Over 3,000” gaming machines. A $365 million resort expansion completed in January of 2017 included the addition of an attached 50,000 square foot Margaritaville casino. As a result, this casino on the banks of the Arkansas River is now the country’s 4th biggest casino.

San Manuel Indian Bingo & Casino in California has 4,200 slot machines.

5) San Manuel Indian Bingo & Casino – Highland, California: 220,000 square feet. 4,200 slot machines. Over 100 table games, (including their poker room).

Oftentimes erroneously quoted as having “480,000 square feet,” this popular Indian Casino 70 miles east of Los Angeles has 1 million square feet of total resort space (including garages), and 480,000 of indoor space.

However of the 480,000 total indoor space, 220,000 square feet is gaming space. This is according to Lochsa Engineering, who says they helped built the building, which was completed in 2004.

6) Riverwind Casino – Norman, Oklahoma: 219,000 square feet. 2,700 gaming machines

7) Choctaw Casino Resort – Durant, Oklahoma: 218,000 square feet. 3,500 gaming machines.

Other Biggest Casinos in the United States

Here are some of the other largest casinos in the United States, however we have been unable to find hard data on their square footage. If a large casino is not listed here, it’s because we were unable to find data on either their size or slot-machine count. If you happen to know, it, please let me know. Thank you.

Treasure Island Resort & Casino – Welch, Minnesota. 2,500 slot machines. 58 table games.

Pala Casino Spa Resort – Pala California. 2,000 gaming machines. 95 total table games.

Jackpot Junction – Morton, Minnesota. It’s website claims it has “440,000 square feet of exciting gaming action” however with relatively few slot machines (1,200), and just 24 table games, I find this very dubious, even considering their 250 seat bingo hall. More likely, they are counting the entire resort and hotel square footage in the 440,000 figure.

Graton Resort & Casino – Rohnert, CA. 3,000 slot machines. 144 table games. A 20 table poker room.
