The Largest Casinos In The United States

Casino gambling in the United States is spread across more than a thousand floors. Federal regulators counted 545 tribal gaming operations in 29 states during fiscal 2025, which won a record $46.2 billion, while the commercial industry reported 493 casinos across 27 states. Size varies widely within that field, from roadside rooms with a few dozen machines to resorts built on a scale comparable to small cities. Published gaming-floor space is the measure used here, excluding hotel towers and convention halls. WinStar World Casino & Resort leads at nearly 400,000 square feet, while Tulalip Resort Casino edges past the 270,000-square-foot tie between Thunder Valley and Morongo. Nine of the ten entries are tribally owned. Figures use the latest comparable measurements available from casino operators or tribal authorities through September 2026. Official government data fills remaining gaps, while Yaamava's exact figure is the one non-primary exception and is identified in its entry.

WinStar World Casino & Resort

WinStar World Casino & Resort in Thackerville, Oklahoma, has nearly 400,000 square feet of gaming floor, the largest published figure in this ranking. The Chickasaw Nation opened a bingo hall beside Interstate 35 in 1991, then expanded it to 190,000 square feet and renamed it WinStar Casino in 2003. A major expansion was completed in 2008, introducing the internationally themed gaming plazas that remain a distinctive feature of the property. The WinStar Convention Center followed in 2016. Today, WinStar has nine gaming plazas and more than 10,000 electronic games. Its current gaming page also lists 92 table games. WinStar remains open in 2026, although its poker room and several other gaming operations are temporarily closed.

Foxwoods Resort Casino

Foxwoods Resort Casino in Mashantucket, Connecticut, opened in 1992. A 2020 Foxwoods property fact sheet, cited in Connecticut's 2024 statewide gambling report, put its gaming floor at 340,000 square feet. The same state report notes that Foxwoods added the 50,000-square-foot Pequot Woodlands Casino in 2023, after that aggregate figure was published. Foxwoods no longer publishes one current combined floor total, so 340,000 square feet is used here as the last exact comparable baseline. The Mashantucket Pequot Tribal Nation owns and operates the resort. Foxwoods currently advertises more than 3,200 slot machines and 175 table games. It also has more than 1,900 hotel rooms across three towers. The resort remains open in 2026.

Mohegan Sun

Mohegan Sun in Uncasville, Connecticut, currently reports more than 300,000 square feet of gaming space. The Mohegan Tribe opened the resort on October 12, 1996, on 185 acres beside the Thames River. Casino of the Earth opened first, while Casino of the Sky followed in 2001. The latter is known for its planetarium dome and 55-foot indoor waterfall. Current Mohegan materials report nearly 4,000 slot machines and more than 300 table games across the property. The resort also has two hotel towers and a 10,000-seat arena. Mohegan Sun remains fully operational in 2026, with its gaming concentrated in Casino of the Earth and Casino of the Sky.

Choctaw Casino & Resort Durant

Choctaw Casino & Resort Durant in Oklahoma uses a published 300,000-square-foot casino figure for this ranking. The Choctaw Nation documented the 300,000-square-foot casino during construction in 2009, with the expansion opening in 2010. Another major expansion opened in 2021 and enlarged the non-smoking gaming area, although Choctaw does not currently publish a newer combined gaming-floor measurement. Current resort materials list 7,400 slot machines and 100 table games. The property also includes The District, where visitors can find bowling and a six-screen cinema. Choctaw Casino & Resort Durant remains open around the clock in 2026. Its later expansion means the 300,000-square-foot figure should be read as a published comparison baseline rather than a precise measurement of the current gaming floor.

Yaamava' Resort & Casino

Yaamava' Resort & Casino in Highland, California, is listed as having about 290,000 square feet of gaming floor. Yaamava' itself does not publish one combined square-foot total, making this the only entry whose exact ranking figure is not available from a primary or government source. The Yuhaaviatam of San Manuel Nation opened a bingo hall in 1986 and expanded it into a 100,000-square-foot casino in 1994. A major gaming expansion opened in 2021, when the property also adopted the Yaamava' name. The resort now advertises more than 7,500 slot machines and more than 150 table games. It also has five high-limit gaming rooms and a theater. Yaamava' remains fully operational in 2026.

Tulalip Resort Casino

Tulalip Resort Casino in Tulalip, Washington, expanded to 270,250 square feet of gaming space in July 2025. The Tulalip Tribes opened the resort casino on June 5, 2003, building on earlier tribal gaming operations in the area. The 2025 project added 70,250 square feet and brought the slot-machine total above 2,600. Current resort information also lists 38 live-dealer table games. New entrances introduced prominent Tribal design work, including metallic spindle-whorl elements associated with Tulalip storytelling. Renovation work across the existing casino is scheduled to continue through late 2026. The casino and hotel remain open while that work progresses.

Thunder Valley Casino Resort

Thunder Valley Casino Resort in Lincoln, California, has 270,000 square feet of gaming space, tying Morongo Casino Resort & Spa on the published figure used here. The United Auburn Indian Community opened Thunder Valley in June 2003. A major expansion in 2010 added a 17-story hotel and resort pool. The Venue followed in 2023 as a 4,500-seat indoor entertainment space. Thunder Valley currently reports 3,500 slot and video machines along with 90 table games. The casino also operates a live poker room and a bingo room. Thunder Valley remains open in 2026, with its hotel and entertainment facilities operating alongside the casino.

Morongo Casino Resort & Spa

Morongo Casino Resort & Spa in Cabazon, California, also reports 270,000 square feet of gaming space, tying Thunder Valley. The Morongo Band of Mission Indians began gaming with a bingo hall in 1983, while the current resort opened in late 2004. Morongo now advertises nearly 4,000 slot machines and more than 80 table games across its casino. One of the property's most recognizable features is its 27-story hotel tower beside the San Gorgonio Pass. The resort also includes a bowling center and the Oasis pool complex. Morongo remains fully operational in 2026 and continues to identify its 270,000-square-foot casino as one of the largest tribal gaming facilities in the western United States.

Resorts World New York City

Resorts World New York City in Queens opened at Aqueduct Racetrack in 2011. The operator's 2024 capital plan listed an existing casino footprint of 250,000 square feet, with additional gaming space planned inside the existing building. Resorts World became New York City's first full commercial casino on April 28, 2026, when live table games and commercial casino slots opened. Another gaming floor reopened in July, bringing the property to 3,900 slot machines. Resorts World has not published a final combined floor measurement for the expanded 2026 casino, so this ranking uses the 250,000-square-foot figure as a conservative published baseline. Phase Two of the resort expansion broke ground in July 2026 and remains under construction.

Seminole Hard Rock Hotel & Casino Tampa

Seminole Hard Rock Hotel & Casino Tampa in Florida has 245,000 square feet of gaming space. The Seminole Tribe of Florida transformed its Tampa casino into the Hard Rock property in 2004, then completed a $700 million expansion in 2019. Current operator materials list about 5,230 slot machines and more than 175 table games. Music memorabilia displayed throughout the property provides one of the resort's signature attractions away from the gaming tables. Seminole Hard Rock Tampa remains open in 2026, although another change is underway. The resort announced a temporary casino area for late September while a smoke-free gaming section is renovated. The published 245,000-square-foot casino figure is the measurement used for this ranking.

Measuring America's Largest Casinos

Gaming-floor measurements show why defining "largest" matters. WinStar leads the published figures used here, while Tulalip narrowly exceeds the 270,000-square-foot totals reported by Thunder Valley and Morongo. Several properties have expanded since their last combined floor measurement was published, making date-stamped sourcing essential. Resorts World New York City is still expanding in 2026, while Foxwoods no longer publishes a current aggregate total. The ranking can therefore change as operators release updated measurements.
