Top 10 Biggest Casinos in the World by Size and Revenue

The ten biggest casinos in the world have enormous indoor spaces, impressive acreage, and five-star accommodations. Although their size alone is enough to leave you in awe, it’s their Michelin-star restaurants, designer shops, and top-notch game lobbies that will keep you coming back for more.

10 Biggest Casinos in the World by Size

Contrary to what people might think after watching movies like Hard Eight, the biggest casinos in the world by size are not located in Las Vegas. 

Here’s a complete list of the largest gambling venues and their locations:

#1. Casinò di Campione [Lugano, Italy]

Spread across 610,000 square feet, Casinò di Campione is by far the biggest casino in the world. Located on the shores of Lake Lugano, it has had a tumultuous past. The casino was originally established in 1917 but moved to its new location in 2007. Then, it temporarily closed in 2018 but reopened in January 2022.

Casino di Campione is spread over 9 stories, and it has 3 underground parking levels. Its players can enjoy 56 gaming tables—including blackjack and baccarat—and more than 500 slot machines. The architect behind this impressive and massive structure is Mario Botta.

#2. Venetian Macau [Macau, China]

The Venetian Macau—the second-biggest casino in the world—is also the largest single-structure hotel in Asia. It was built in 2017, and it has 540,000 square feet of casino floor space. Moreover, there are over 3,000 rooms in the Venetian Macau, as well as a few Michelin-star restaurants.

More than 800 table games and 3,400 slots await all players visiting the biggest casino in Asia. While the versatility of games is the most important thing for its visitors, it also doesn’t hurt that the Venetian Macau is one of the most unique and aesthetically appealing casinos in the world.

The structure includes canals with bridges and gondolas, a live arena, and more than 350 shops.

#3. WinStar World Casino [Oklahoma, USA]

While most people would likely expect the biggest casino in the USA to be somewhere in Las Vegas, WinStar World Casino is actually located in Oklahoma.

It’s interesting to note that many sources list this one as the biggest casino in the world; while it does have 630,000 square feet if you include the entire compound, the gaming space takes up only 519,000 of it, which is the square footage we took into account.

WinStar World Casino is special, as it has nine globally-themed gaming plazas. You can go to the Beijing Gaming Plaza for a taste of the Far East and then hop to New York, where gaming never sleeps. The casino also has an impressive poker room, lightning link lounge, and a dedicated area for high rollers where the stakes reach incredible amounts.

#4. Wynn Palace Macau [Macau, China]

Wynn Palace Macau is among the biggest casinos in the world, as it spreads over 424,000 square feet. But the impressive size of this luxurious casino isn’t the only thing that makes it memorable—its stunning floral decor sets it apart from other establishments on the list as well.

Many floral sculptures and installations throughout the casino give it a unique touch, and the choreographed fountain show adds to the charm.

Players who plan to visit Wynn Palace Macau should keep in mind that this is a high-roller casino. Most table games have high minimum bet limits, with baccarat having a roughly $375 minimum per hand. The next to follow is blackjack, with a $65 minimum per hand.

#5. City of Dreams Macau [Macau, China]

Located in front of the Wynn Palace, City of Dreams Macau has 420,000 square feet. Three separate casinos make up this large complex, and they have an abundance of high-limit and VIP spaces. The minimum limits per hand aren’t as high as in some other casinos, but players will still have to fork out $250 per hand of baccarat.

The design of the casino is hyper-modern. Thus, its visitors either love or hate the exterior and interior of the facilities, depending on their personal preferences. The resort has Michelin-starred restaurants and the Dancing Water Theater, which can accommodate 2,000 people.

#6. Galaxy Macau [Macau, China]

Galaxy Macau is one of the best casinos in the world when it comes to the number of games. The casino has 400,000 square feet, which is less than half of the entries on our list.

However, the Galaxy Macau boasts more games than some other entries—it provides 600+ slot machines, roulette, baccarat, and blackjack, all of which are featured in an open-concept gaming space.

Even though the Galaxy Macau was a $1.9 billion project, it’s much more affordable than some other places on our list, as the rooms are cheaper and the contents of the minibar are free. The casino also has lower minimum bet limits, so it’s suitable for players with both hefty and modest budgets.

#7. Foxwoods Resort Casino [Connecticut, USA]

Foxwoods Resort Casino is jam-packed with 3,400 slot machines and hundreds of table games, such as roulette, poker, and craps. In more than 30 years in business, the casino has made $4 billion in revenue, which came from the 330 million visitors they had.

Foxwoods Resort Casino is spread across 344,000 square feet, and it features a blend of casino games, fine dining, and excellent entertainment options.

A huge renovation plan for Foxwoods Resort Casino was revealed in 2022, and the budget for the project was $85,000,000, which included the opening of yet another casino on the same land.

#8. Wynn Macau [Macau, China]

Don’t confuse Wynn Macau with the Wynn Palace Macau, as the former spreads across 273,000 square feet.

The entire casino oozes class, elegance, and old-school luxury. It also has what’s considered to be the best poker room in town, so it’s recommended for players who love this classic game. Likewise, they are the only casino in Macau that offers Pot-Limit Omaha, and the blinds for this game are set at $12.50 and $25.

This premiere casino and hotel is operated by international resort developer Wynn Resorts. It welcomed its first players in 2006, and the second tower—Encore—opened in 2010.

#9. Ponte 16 Macau [Macau, China]

Out of all the other casinos in the city, Ponte 16 Macau has the best location. All 270,000 square feet of it are spread across the road from old Macau, and the entire structure has that glamorous, old-school European vibe. Apart from the vast gaming space, Ponte 16 Macau also has 408 rooms and 19 exclusive mansions.

As far as the gaming experience goes, players will only have a combined total of 400 slots and table games to choose from. However, this number doesn’t include games that are available in the VIP space, meaning that high rollers will have more options.

Ponte 16 Macau has some of the lowest minimum bet limits out of all the casinos on the list, with blackjack tables starting at $12.50.

#10. Rio Casino Resort [Klerksdorp, South Africa]

Unsurprisingly, Rio Casino Resort has a Brazilian Carnival theme. Located on 266,330 square feet, this casino is the largest one south of the equator. Rio Casino Resort has games and betting limits that are much more affordable in comparison to other entries on the list.

However, the casino also has a more modest selection of games, as it hosts 274 slot machines and 12 different types of table games. You can try them out by booking one of their affordable rooms, which cost around $100 per night.

5 Biggest Casinos in the World by Revenue

Las Vegas might not have gigantic establishments when it comes to size, but the city has some of the biggest casinos in the world in terms of revenue. Here’s a list of the richest casinos in 2024:

#1. Las Vegas Sands Corporation

With an annual profit of $13.7 billion, Las Vegas Sands Corporation paves the way as the richest casino group in the world. It’s sufficient to say that the corporation owns its own private fleet of aircraft dedicated to executive bigwigs, high rollers, and VIP members.

The corporation combines care for its clients with world-class gaming floors. Las Vegas Sands Corporation was founded in 1988, and it has since become a Fortune 500 company.

#2. MGM Resorts

Following closely in revenue, MGM Resorts rakes in around $12.89 billion per year. The corporation is the biggest casino operator on the Strip, and they also do business in Macau and six other US states. Likewise, they don’t plan to stop there, as they want to spread to Japan and the UAE.

Their incredible success comes from world-renowned gaming areas that are coupled with top-notch hospitality. MGM Resorts offers exciting nightlife, spectacular entertainment, and excellent dining by celebrity chefs, so they are a full package deal.

#3. Caesars Entertainment

Caesars Entertainment is one of the most well-known names in the gambling industry. Many professional gamblers started their careers at Caesars Entertainment’s first parlor in Reno, Nevada, in 1937. In 2020, the company merged with El Dorado Resorts and became the largest gaming company in the US.

Today, Caesars Entertainment’s portfolio includes 50 casinos across different continents, each of them offering a unique ambiance that gamblers remember long after leaving the premises. Thus, they make an annual profit of around $8.74 billion.

#4. Galaxy Macau

Galaxy Macau was already mentioned on the list of the biggest casinos in the world by size, and it’s also the most profitable stand-alone casino in the world. It has an annual profit of over $8 billion, and it’s been topping the charts for the richest casinos since 2011.

Apart from its impressive size and a staggering number of new slots and classic table games, the entire complex has over 3,000 rooms, 200 luxurious brands, and 120 restaurants.

#5. Wynn Resorts

Wynn Resorts brings in total revenue of over $6 billion. The company was founded by Steve Wynn and Kazuo Okada in 2002. Together, they created five properties in Las Vegas and Macau. Another one was later opened in Massachusetts, and there are plans for other openings in the years to come.

The reason why their casinos generate so much profit lies in their integration with world-class amenities. From exquisite retail stores to spas and golf courses, Wynn Resorts provides its visitors with an all-encompassing experience.

However, the amenities are not compulsory for a casino to make a lot of money, as there are many online casinos that generate staggering profits without offering any luxurious facilities or related services to their visitors. 

Some of the giants we mentioned also have online divisions, but there are many casinos that operate only in the digital realm and still boast astonishing revenues.  

The Revenue of the Online Casino Market

The revenue of the global online casino market isn’t too far behind the top entries on our list. The first online gambling venue opened in October 1994; today, the market comprises more than 4,000 casinos worldwide. 

To get an idea of just how monumental their revenue is, note that the entire online gambling market was valued at $63.53 billion in 2022. It’s projected to grow by 6.20% annually, which would result in a market that will be worth $136.30 billion by 2029.

Thus, if we were to look at average values, we’d see that one online gaming house makes around $15 million per year. Since there’s nothing average about the best online casinos in the UK, most of them generate a lot more profit than the median value.

Casinos such as MagicRed Casino and PlayOJO have rich game libraries, favorable deposit and withdrawal methods, and many accepted payment options. Therefore, they are among the most popular destinations for the UK’s online gamblers.

Keep in mind that—unlike land-based casinos—online casinos can’t profit from hotel rooms and fine dining, so their only source of revenue is casino games, such as online slots and roulette games. Still, this fact doesn’t stop the top gambling sites in the world from making close to $10 billion annually.

Key Takeaways

Whether you want to take a spin on the slot machine, try your hand at poker, or play a classic blackjack game, you are going to have the most special time by doing it in one of the biggest casinos in the world. Not only do they offer an impressive number of games, but they also come with special amenities.

The world’s largest casinos in size and revenue make it possible to enjoy a spa day, preceded by a fun night of gambling and a relaxing stay in a luxurious room. Take your gambling sessions to the next level by visiting one of the impressive casinos on our list.
