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

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.

The WinStar World Casino & Resort has more slot machines and casino floor space than any other casino in America.
The WinStar World Casino & Resort has more slot machines and casino floor space than any other casino in America.

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

Foxwoods is the the country’s second largest casino

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, at least to me, the four largest casinos in the United States are either in Oklahoma or Connecticut. Four of the ten are in the Sooner State.

Largest Casinos in the U.S.

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

  1. Winstar World Casino and Resort – Thackerville, Oklahoma.
  2. Foxwoods Resort Casino – Mashantucket, Connecticut
  3. Choctaw Casino Resort – Durant, Oklahoma
  4. Mohegan Sun – Uncasville, Connecticut
  5. Thunder Valley Casino Resort – Lincoln, California
  6. Seminole Hard Rock Hotel & Casino Tampa – Tampa Bay, Florida
  7. Yaamava Resort & Casino – Highland, California
  8. Riverwind Casino – Norman, Oklahoma
  9. (Tie) Encore Boston Harbor – Boston, Massachusetts & Soaring Eagle Casino Resort – Mt. Pleasant, Michigan.
  10. River Spirit Casino Resort – Tulsa

More specific information about each casino can be found further below.

Please note that I’ve spent hours trying to find a definitive top ten list, however many Indian casinos do not publish, (or maybe do not know?)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 may normally make the list have been omitted in cases where I could not reasonably verify the square footage of actual gaming space and/or slot machine count.

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.

Mohegan Sun’s two hotel towers combine to provide just over 1,500 hotel rooms, while the resort also boasts two spas 375,000 square feet of convention space, 135,000 square feet of shopping, the 10,000 seat Mohegan Sun Arena entertainment venue, and 45 different restaurants and bars.

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.

Live! Casino & Hotel Philadelphia – The resort near the stadium homes of the Philadelphia Eagles and Phillies boasts a property just over a half million square feet, but we’re unsure as to how much of that is casino space. It does have 2,100 slot machines, 121 table games and a 29 table poker room.
