Top Ten Biggest Casinos in U.S. – by Gaming Square Footage

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 just under 400,000 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 8,100 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, to free up space for more bars, clubs and restaurants.

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).

Please note that I’ve spent hours trying to find a definitive top ten list, however many Indian casinos do not publish, (or maybe do not know?)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 square footage data could be verified.

1) WinStar World Casino and Resort – Thackerville, Oklahoma. 400,000 Square feet. 8,100 gaming machines. 100 table games, not including their 55 table poker room. Thanks to traffic from the Dallas/Ft. Worth area, (and a near-casino monopoly in the region), this busy casino in far southern Oklahoma takes top billing.

2) Foxwoods Resort Casino – Mashantucket, Connecticut. 344,000 square feet. 4,800 gaming machines. 280 table games. Two out of three of the nation’s biggest casinos are in Connecticut.

3) Mohegan Sun – Uncasville, Connecticut. 299,000. 5,087 slot machines and 350 table games.

This is that rare casino to downgrade in square footage. Due likely to more casino competition popping up in the region, Mohegan Sun closed one of the three different casino areas under its roof in 2019. The combined square footage of the remaining two casinos under the roof: Casino of the Earth, and Casino of the Sky, is just shy of 300,000. Prior to the closing of the Casino of the Wind, Mohegan Sun had 344,000 square feet, – the exact same as Foxwoods, its Indian cousin ten miles to the east.

4) Thunder Valley Casino Resort – Lincoln, California. Just to the north of Sacramento, Thunder Valley boasts 42 acres of parking!

Inside you’ll find 250,000 square feet, 3,400 slot machines, and over 100 table games. There’s also a 7,000 square foot 27 table poker room and 13,000 square foot bingo hall that can seat 800 players.

5) Seminole Hard Rock Hotel & Casino Tampa – The Tampa Bay area’s only casino now has 245,000 square feet of casino floor space. An expansion completed in 2019 brought this popular casino seven miles north east of downtown Tampa into the top five. There are just under 5,000 slots here, along with 179 table games and a 46 table poker room.

6) San Manuel Indian Bingo & Casino – Highland, California: 220,000 square feet. 4,700 slot machines. Over 100 table games, but no 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 build the building, which was completed in 2004.

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.
