Biggest Vegas Casinos

Las Vegas is known as the entertainment capital of the world, and it’s no surprise that it’s home to some of the largest and most extravagant casinos on the planet.

As the biggest poker news site around, we're no strangers to the bright lights and inviting tables of Sin City, but we recognize that not everyone has the inside track on the casinos and hotels worth checking out.

To rectify that, in this guide we'll delve into the biggest casinos in Las Vegas, exploring their size, features, and ownership. By the end, you’ll have a deep understanding of what makes these colossal casinos the giants of the gaming world.


What is the Biggest Casino in Las Vegas?

For visitors, the sheer size and grandeur of these gaming palaces can be overwhelming. But what exactly makes a casino the biggest? And which one holds that title in the City of Lights?

We know that although square footage is a factual number, the 'size' of one casino resort compared to another is a subjective matter and sometimes down to personal opinion. We've discussed this in more detail below, but to summarize, each resort was evaluated on the following criteria:

  • Total gaming space in square feet
  • Number of slots
  • Number of tables
  • Number of hotel rooms
  • Standout features

When it comes to the biggest casino in Las Vegas, the title goes to Wynn/Encore Resort and Casino. This iconic complex isn't just the largest in Las Vegas—it's among the largest in the world.

This complex is actually two hotels connected by a sprawling casino floor, on which you'll find a gaming experience that's hard to match. The Wynn/Encore stands out not just for its size but for its design features and amenities, making it arguably the premier casino destination in Las Vegas.

Who Owns the Biggest Casino in Las Vegas?

Ownership plays a crucial role in the operations and branding of Las Vegas casinos. The biggest casino, Wynn/Encore, is owned by Wynn Resorts, a company founded by the legendary Steve Wynn.

Market ImpactWynn Resorts is known for its luxury-focused approach, setting a high standard for casino experiences. The company’s properties are synonymous with elegance, high-end service, and world-class amenities.

Other Major Owners in Las Vegas

Alongside Wynn Resorts, there are a number of other sizeable corporations with stakes in the largest casino resorts in Vegas:

  • MGM Resorts International: A giant in the industry, owning properties like the MGM Grand, Mandalay Bay, and ARIA. MGM Resorts is one of the largest casino operators in the world.
  • Caesars Entertainment: Another major player, known for iconic properties such as Caesars Palace and Harrah’s. The company has a vast portfolio of properties across the U.S. and globally.
  • Vici Properties: A real estate investment trust (REIT) that owns The Venetian and Palazzo, among others. Vici focuses on acquiring and leasing gaming, hospitality, and entertainment properties.

These corporations not only own the biggest casinos but also shape the landscape of Las Vegas through their influence and investments. Many of these corporations have also ventured into online casino gaming, for example, MGM, who operate the BetMGM Casino and Borgata Casino brands.


What Makes These Casinos the Biggest?

When discussing the 'biggest' casinos, personal opinion and what we deem to be important, often carries a lot of weight. Therefore it’s essential to understand what factors contribute to evaluating each casino resort on our list:

1. Gaming Space

The most obvious measure of a casino’s size is its gaming space. This includes the area dedicated to slot machines, gaming tables, poker rooms, and sports betting. Casinos like Wynn/Encore and MGM Grand dominate in this category, offering vast floors filled with a variety of games.

2. Hotel Rooms

Another critical factor is the number of hotel rooms. Las Vegas casinos often double as hotels, with thousands of rooms available for guests. For example, The Venetian and Palazzo complex boasts over 7,000 rooms, making it one of the largest hotels in the world.

3. Amenities and Entertainment

Size isn’t just about square footage. The amenities offered by a casino also contribute to its stature and popularity with guests. Casino resorts often include restaurants, theaters, shopping centers, spas, and pools. The MGM Grand, for instance, is renowned for its entertainment options, from concerts to famous bouts.

4. Architectural Design

The design and architecture of a casino can also contribute to its perception as the biggest. Elaborate themes, luxurious interiors, and grand exteriors all play a role. The Venetian, with its intricate replication of Venice’s canals and architecture, is a prime example. Caesars Palace is also held up as an example of classic hotel elegance.

5. Customer Experience

Finally, the overall customer experience is a significant factor. Large casinos often offer more personalized and high-end services, such as VIP rooms, private gaming areas, and exclusive events. This focus on luxury and exclusivity can elevate a casino’s status as one of the biggest.
