The record
The biggest casino in the world is WinStar World Casino and Resort, in the United States — 519,000 sq ft (48,217 m²), gaming floor area.

Las Vegas does not appear on this list at all. The MGM Grand runs the largest gaming floor in Nevada at 144,000 sq ft, barely a quarter of what the leader spreads out, and every famous name on the Strip sits well below the cut. What tops the table instead is a Chickasaw Nation property a mile north of the Texas border, trailed by a run of eight casinos in Macau.
This countdown ranks the licensed gaming floor as the operator or regulator states it — the room you actually gamble in, not the hotel towers, shopping malls and convention halls wrapped around it, which is why Galaxy Macau's 1.4 million square metre resort contributes only its casino here.
Every entry is open today, so the 350,000 sq ft floor planned for Resorts World New York City waits until it exists rather than being counted from a drawing. The figures run from 519,000 sq ft down to 250,600.
Not one Las Vegas casino makes the top fifteen. The MGM Grand has the largest gaming floor in Nevada at 144,000 sq ft, according to MGM Resorts' own annual report — roughly a quarter of what WinStar spreads across the Oklahoma prairie.
Nine of the fifteen are in Macau, a territory of about 33 square kilometres. The Cotai Strip alone, built on reclaimed land between two islands, holds seven of them.
The biggest casino on Earth is not a single room. WinStar's floor is laid out as nine themed plazas — Rome, Paris, Beijing, Madrid, Vienna among them — each with its own scaled-down facade.
A bigger floor does not mean more machines.Wynn Palace carries 693 slot machines across 468,000 sq ft; WinStar fits over 10,000 electronic games into 519,000. Macau builds for high-stakes baccarat, America for volume.
Most published rankings are quoting 2007. The 550,000 sq ft figure attached to The Venetian Macao across the web traces to a Casino City Times article from December 2007; Las Vegas Sands has reported 503,000 sq ft for years.
One casino ranked fourth in the world almost everywhere does not belong on the list at all. South Africa's Rio Casino Resort is credited with 266,330 sq ft by nearly every ranking, but its operator advertises 274 slot machines and 12 tables — that figure covers the resort and convention complex, not the gaming floor.
At 519,000 sq ft, WinStar World Casino and Resort spreads the largest gaming floor on Earth across the Oklahoma prairie, about a mile north of the Red River and the Texas state line.
The Chickasaw Nation built it in stages rather than all at once, and the result is not one enormous room but nine themed plazas laid end to end — Rome, Paris, Beijing, Madrid, Vienna and the rest — each fronted by its own scaled-down facade, so walking the floor feels like crossing a very strange border every few hundred paces.
The scale shows up in the machine count more than the architecture: the property offers over 10,000 electronic games, roughly 100 table games and a 55-table poker room, which is several times what a Las Vegas resort of comparable floor area carries.
Worth knowing that this top spot is genuinely contested. The 519,000 sq ft figure is WinStar's own; a much-repeated 600,000-plus circulates online with no operator behind it, while Wikipedia still cites 370,000 from a book published before three separate expansions.
At 503,000 sq ft, The Venetian Macao holds the largest casino floor in Asia and misses the world title by about 16,000 sq ft. That number comes from Las Vegas Sands' own annual report, and it is worth pausing on, because almost every list you will find puts this casino at 550,000 sq ft and calls it the biggest anywhere.
That figure traces back to a Casino City Times article from December 2007, the year the resort opened, and the operator's filings have said something different for a long time.
The casino sits under a replica of Venice, complete with indoor canals, gondoliers who sing, and a painted sky that stays a flat late-afternoon blue whatever the hour outside. When it opened it was effectively alone on reclaimed land between Taipa and Coloane; the Cotai Strip that now holds most of this countdown grew up around it. Baccarat dominates the tables, as it does across Macau, and the mass-market floor and the private VIP rooms are worlds apart in atmosphere.
At 468,000 sq ft, Wynn Palace puts the third-largest gaming floor in the world under a resort better known for what surrounds it than what happens on the tables. SkyCab gondolas run out over an eight-acre performance lake, and the interiors lean on flowers — a rotating carousel of floral sculptures that has become the property's signature — rather than the themed-city approach of its Cotai neighbours.
The floor is a good illustration of how differently Macau and America use space. Wynn Resorts' annual report puts 305 table games and 693 slot machines on those 468,000 sq ft, which works out at roughly 470 sq ft per gaming position.
A large American casino runs at a fraction of that, packing banks of machines into the same area. Macau's floors are built around high-stakes baccarat played at generously spaced tables and in private salons, so a bigger room here does not mean more places to sit.
At 420,000 sq ft, City of Dreams anchors Melco's half of Cotai directly across the road from The Venetian Macao. The property is easiest to recognise by Morpheus, the Zaha Hadid-designed hotel tower whose exposed steel exoskeleton wraps a building with no internal columns, and by The House of Dancing Water, the aquatic production staged in a purpose-built theatre holding a tank several times the volume of an Olympic pool.
This is the first entry on the countdown whose figure does not come from the operator. Melco publishes plenty about its hotels, restaurants and shows but no gaming-floor area, so the 420,000 sq ft here is the industry-register number, and its paper trail runs back to reporting from around the resort's 2009 opening. The floor has been reworked more than once since, so treat the figure as a well-established estimate rather than a filed measurement.
At 400,000 sq ft, The Londoner Macao carries a gaming floor almost as large as the Venetian's, under a facade that reproduces the Houses of Parliament and a full-height Big Ben. The property is a rebuild rather than a new resort: Las Vegas Sands spent years converting what had been Sands Cotai Central into a single London-themed address, finishing the work in 2025, and the casino was expanded and reorganised along the way.
Its figure sits in an exact tie with Galaxy Macau, the next entry, and the tie is broken here on evidence rather than on size. The 400,000 sq ft for The Londoner Macao is stated in Las Vegas Sands' annual report to shareholders; Galaxy's equivalent number is an industry estimate its operator has never published. Where two casinos measure the same, the one whose figure is filed rather than inferred takes the higher rank.
At 400,000 sq ft, Galaxy Macau ties The Londoner Macao and takes sixth place on the tiebreak described above. By most other measures it is the largest single resort complex in this countdown — the property runs to roughly 1.4 million square metres across its completed phases, with eight hotels, a rooftop wave pool fed by an artificial beach, and a fourth phase still going up.
Almost none of that counts here, which is the clearest demonstration of why the basis rule matters on a list like this.
Galaxy Entertainment reports its footprint in the millions of square metres and its gaming performance in revenue, but it has never published the area of the casino itself, so the 400,000 sq ft is an industry-register figure and the softest number in this top ten. Quoting the resort's full footprint instead, as several published rankings do, would put Galaxy Macau first by a factor of nearly forty.
At 376,700 sq ft — about 35,000 square metres — Okada Manila runs the largest gaming floor in the Philippines and the only entry on this countdown from outside the United States and Macau, apart from its neighbour a few ranks below. It sits in Entertainment City, the reclaimed casino district on Manila Bay in Parañaque, behind a curved gold facade and a dancing fountain that the resort claims as the largest of its kind.
This is the least certain figure in the fifteen, and it is worth saying so plainly. Published sources for the same floor range from 26,411 square metres up to 42,000, a spread of more than sixty per cent.
The number used here is the one filed with the US Securities and Exchange Commission during the resort's attempted 2021 listing, which is the highest-quality source of the three; the operator's own marketing quotes the largest figure and Wikipedia the smallest. On the top of that range Okada Manila would rank fourth.
At 352,000 sq ft, Mohegan Sun holds the second-largest casino floor in the United States, though it does not present it as one space. The gaming is split across three connected casinos — Casino of the Earth at roughly 188,000 sq ft, Casino of the Sky at 119,000 and Casino of the Wind at 45,000 — each with its own character, and the seasons-and-elements theming runs through the architecture rather than sitting on top of it as a facade.
The Mohegan Tribe has financed the property through publicly traded debt for decades, which is why the floor areas above are stated in annual reports rather than estimated by outsiders — a rarity among the tribal casinos on this list.
The wider resort wraps the gaming in a 10,000-seat arena that hosts a professional basketball team, a glass-domed shopping concourse, an indoor planetarium dome over Casino of the Sky, and enough restaurants to make the place function as a small town in eastern Connecticut.
At 344,000 sq ft, Foxwoods Resort Casino sits a few miles down the road from Mohegan Sun in Ledyard, Connecticut, and for much of the 1990s and 2000s it was the largest casino in the Western Hemisphere.
The Mashantucket Pequot Tribal Nation opened it in 1992 on the back of a high-stakes bingo hall, and its success is the reason a rural corner of New England now holds two of the biggest gaming floors on the planet within a fifteen-minute drive of each other.
Neither Foxwoods nor the Tribal Nation publishes a gaming-floor area today — the resort's own about page quotes its meeting space but not its casino — so the figure here comes from the industry registers, where 340,000 and 344,000 both circulate. The property is really several connected casinos joined by long concourses, which is why first-time visitors reliably get lost between the poker room and the hotel.
At 323,000 sq ft, or about 30,000 square metres, Newport World Resorts gives the Philippines a second entry in the top ten and sits directly opposite Ninoy Aquino International Airport in Pasay, close enough that arriving passengers can reach it in a few minutes. It opened in 2009 as the country's first integrated resort, some years before Entertainment City took shape along the bay, and was renamed from Resorts World Manila in 2022.
The complex is less a single casino than a covered district, with the gaming floor threaded between a shopping mall, a theatre staging full-scale musicals, and several hotels under different brands. Its operator does not publish a floor area, so this figure comes from the industry registers; the roughly 300 table games and 1,500 machines it carries are consistent with a room of that size by Asian standards.
At 294,000 sq ft, Wynn Macau is the largest casino on the Macau Peninsula rather than out on Cotai, standing on the waterfront across from the old Lisboa. It opened in 2006 as the first Wynn property outside Nevada, and its arrival pushed the peninsula's older gaming halls toward the luxury positioning that now defines the whole territory. The Performance Lake out front runs choreographed water shows against the harbour.
Its figure sits within about 4,000 sq ft of Yaamava', the next entry — a gap of well under two per cent, close enough that a single remodel at either property could reverse the order. Both are ranked on current filings and treated here as effectively level. Inside, the split that runs through this whole countdown is on display again: 253 table games against 911 slot machines, a ratio no American casino of this size would recognise.
At 290,000 sq ft, Yaamava' Resort & Casino runs the largest gaming floor on the west coast of the United States, in Highland at the foot of the San Bernardino Mountains, twenty minutes east of Riverside and about an hour and a half from Los Angeles. The Yuhaaviatam of San Manuel Nation rebuilt and renamed the property through an expansion completed in 2021, adding two floors of gaming, a seventeen-storey hotel tower and a rooftop pool deck.
As noted above, it finishes within a whisker of Wynn Macau, and the contrast between the two is the story of the list in miniature. Yaamava' packs more than 7,000 slot machines and around 150 table games into slightly less floor than Wynn Macau uses for 253 tables and 911 machines. One room is built for volume, the other for stakes, and floor area alone cannot tell them apart.
At 272,000 sq ft, The Parisian Macao completes the run of Las Vegas Sands properties on this countdown, and it is the easiest of them to spot from a distance thanks to the half-scale Eiffel Tower standing over the entrance, lit after dark and open to visitors. The resort opened in 2016, the last of the company's Cotai builds before it turned to redeveloping what it already had.
The gaming floor is stated in the same annual report that supplies the figures for the Venetian, the Londoner and Sands Macao, which makes the four directly comparable — a rarer thing on this list than it ought to be. Sands describes what it counts as gaming space and gaming support area, so a modest amount of back-of-house is included alongside the tables and machines, consistently across all its properties.
At 264,000 sq ft — 24,549 square metres as MGM China reports it — MGM Cotai brings the second American operator onto the Cotai Strip with a building assembled from stacked, offset boxes meant to read as jewellery cases. Its centrepiece is the Spectacle, a glass-roofed atrium wrapped around a garden of mature trees brought in whole and lined with a wall of LED screens the resort bills as the largest permanent installation of its kind.
The property opened in 2018, late enough that its floor was designed around the premium mass market rather than the junket-driven VIP business that shaped the earlier Cotai resorts.
MGM China reports its casino areas in square metres, so the figure here is a straight conversion; the company added a further block of premium gaming space in 2026, described as prioritising quality over scale, and it is not clear whether that space is new floor or a reconfiguration of what was already there.
At 250,600 sq ft, or 23,283 square metres, MGM Macau closes out the top fifteen from a waterfront site on the peninsula next door to Wynn Macau. Its wave-fronted tower is filled out by the Grande Praça, a covered square modelled on a Portuguese town and roofed in glass and steel in the manner of a nineteenth-century railway station — a nod to the four centuries of Portuguese administration that ended in 1999.
It is a close-run cutoff. Seminole Hard Rock Tampa follows at 245,000 sq ft, Crown Melbourne at 220,000 and Choctaw Casino Durant at 218,844, which means the difference between making this list and missing it is smaller than the measurement uncertainty on several entries above. Extend the countdown by three and it gains Florida, Australia and a second Oklahoma entry.
FAQ: The World's Biggest Casinos
What is the biggest casino in the world?
WinStar World Casino and Resort in Thackerville, Oklahoma, with 519,000 sq ft of gaming floor — a figure the Chickasaw Nation states itself. It leads The Venetian Macao by about 16,000 sq ft, which is close enough that the top spot is genuinely contested. A widely repeated 600,000-plus figure for WinStar has no operator source behind it.
How is a casino's size actually measured?
By the licensed gaming floor — the area where gambling takes place — not the resort around it. That distinction does most of the work on this list. Galaxy Macau's complex covers roughly 1.4 million square metres, nearly forty times its casino, and rankings that quote resort footprints instead produce wildly different orders.
Why is there no Las Vegas casino on the list?
Because Las Vegas builds resorts rather than enormous gaming halls. The MGM Grand runs the largest floor in Nevada at 144,000 sq ft, roughly a quarter of WinStar's. Floor space on the Strip went into hotel towers, convention centres, shopping and theatres, while Macau and the big tribal casinos put it into gaming.
What is the biggest casino in Macau?
The Venetian Macao, at 503,000 sq ft according to Las Vegas Sands' annual report — also the largest in Asia. Macau holds nine of the fifteen casinos here, seven of them on the Cotai Strip, a stretch of reclaimed land between Taipa and Coloane that did not exist as buildable ground until the 2000s.
Why do other lists give completely different numbers?
Three reasons. Many quote a Casino City Times article from 2007 without saying so. Some use resort or convention floor area in place of the gaming floor. And several include South Africa's Rio Casino Resort at 266,330 sq ft, though its operator advertises 274 slot machines and 12 tables — a mid-size regional casino, not a global contender.
