With a continent as rich in history as Europe, it’s no surprise that the origins of our modern day casinos stem from this area of the globe. Illegal gambling in the form of dice games took place in Europe as early as 500 B.C., but the first legitimate casinos didn’t pop up in the 17th century. Casinos have come a long way since the 1600s, with Europe alone boasting over 1,000 casinos. But, not all casinos are created equal, and in order to help you sift through the myriad of choices presented throughout Europe, we’ve curated a list of some of Europe’s largest casinos. The bigger the casino, the more options you have in terms of games, jackpots, and entertainment.

In addition to finding you the largest and best casinos, we’ve also taken the time to focus on casinos that are available twenty-four hours a day, seven days a week. Because, let’s face it, if you’re taking the time to find the cream of the crop, you’re going to want to spend as much time there as possible.

However, being the biggest and being open 24/7 do not always coincide. Often times, some of the more well known, luxury casinos will have specific operating hours, for their casino floors as well as their different gaming rooms. Don’t be discouraged if a casino doesn’t fit the 24/7 criteria that you need. Casinos are still in the business of making money, and they know that the longer they are open, the better their chances are at making a profit. So, while some of the casinos on this list may not be open 24 hours a day, they still have lengthy operating hours. On the other side of that coin, there are many casinos throughout Europe that do operate 24 hours a day —they just may not be that big. So, whether you’re after a big, luxurious casino experience, or a casino that fits your availability, we have covered all of our bases with the following list.

When providing information on an assortment of the largest casinos of Europe, it makes sense to start off with the largest one, and that honor goes to the Casino di Campione. This casino was erected in 1917 in Campione d’Italia on the edges of Lake Lugano. The square footage of this compound comes in at a whopping 590,000. It houses three bar/ restaurants and 556 games. Slots and table games are dispersed throughout nine floors. This casino has over 500 slots games and 56 table games, which include baccarat, blackjack, punto banco, and roulette. While this does meet our requirement of being the biggest casino, it sadly is not open 24/7. The hours are still generous though, with an opening time of noon and a closing time of 4 a.m.

Despite coming in second in terms of size, the Casino de Monte Carlo’s reputation is world renowned. You may recognize the name thanks to the fictional spy, James Bond. Not only was it the inspiration for Ian Fleming’s Casino Royale, but it’s also one of the oldest casinos in Europe. It’s a beautiful casino that covers 108,000 square feet. It has over 300 games and boasts 18 different bars and restaurants. The Casino de Monte Carlo may not be open 24 hours a day, but they come fairly close. Their doors open at 2 p.m. and don’t close again until 4 a.m.

One casino that ticks both of our boxes for being large and open 24 hours is the casino at the Empire in London. This casino is over 55,000 square feet and has over 150 games. It’s also home to four different bars and restaurants. It’s operated by Caesars Entertainment, who is responsible for Caesars Palace in Las Vegas. The building itself has been around since the late 1800s, and it has earned the reputation of being one of the top casinos in Europe. And the best part? You can come play games here anytime because it’s doors are never closed.

The Aspers Casino Newcastle may not have the lengthy history as some of the casinos mentioned above, but that doesn’t make it any less of a desirable destination. With over 65,000 square feet, the Aspers Casino Newcastle is home to 27 table games and 90 gaming machines. If these numbers don’t impress you then now would be a good time to mention that this casino has one of the largest poker rooms in the area. The poker room alone consists of 20 tables and 200 seats. So, if you’re a poker enthusiast, this casino is the place for you. Just like the casinos of the Empire in London, the Aspers Casino Newcastle is also open 24 hours a day.

If big destination resorts are more your style, then you’ll want to do some research on the Casino Admiral Gibraltar. Located in Ocean Village on Gibraltar, this casino resort was bought by leading game supplier Novomatic in 2013, It reopened in 2015 bigger and better than ever. This casino is over 25,000 square feet and has 200 gaming machines. Some of these games are Novomatic slot machines that you can’t find anywhere else. Surrounding the casino is the sought after destination of Ocean Village. Ocean Village has a marina, bars, restaurants, shopping, and even a floating casino! In addition to having every luxury available to you, there’s not cut off time when it comes to gambling. The Casino Admiral Gibraltar keeps its doors open all day and night.

Land casinos are common enough around Europe, but what about casinos that aren’t on land— no, not online casinos, but cruise casinos. With ports all over Europe, casino cruise ships have become increasingly popular. These cruise ships are the whole package. Not only do they have entire decks dedicated to gaming machines and tables, but there’s also great restaurants, bars and shopping. Not to mention the rooms on board are usually high quality as well. Some prominent European cruises include: The Baltic Princess Cruise Ship, Cunard Cruises, Golden Star Cruises, and Norwegian Cruise Lines are just a few examples. If you’ve always been a fan of cruises and gambling, European cruise lines are perfect solutions to melding your two favorite things into a vacation of a lifetime.

Even though we are quickly becoming a 24/7 type of world, there is still the slim chance that some brick and mortar casinos will not be available in the wee hours of the morning. So, what is a dedicated player supposed to do during these hours when the natural casinos have closed their doors? Online casinos are here to ease your concern. Almost everything you can find in real life today, can also be found online, and casinos are no exception to this rule. The online gambling market has been booming the past several years. In 2009, the value of the online casino market was roughly $20 billion. By the year 2020, it’s projected that the value will be close to $60 million. That’s over double value in only a little over a decade!

The popularity and growth of online casinos is easy to understand. Online casinos take your favorite games and put them right at your fingertips. There’s no worry about logistics or taking time off of work. You don’t need to spend unnecessary amounts of money on a nice hotel room. You don’t even need to back your car out of the driveway. Online casinos take all of the work out of playing your favorite casino games.

The convenience of online casinos is one thing, but the sheer volume of options you have is another aspect all together. The amount of hits that come back after searching the term “online casino” is staggering. With thousands upon thousands of websites to choose from, you’re bound to find an online casino that suits your particular set of needs. These days, many of the most popular casinos can be played on mobile devices, such as an iPhone, iPad, Android or table device. So, even if you find yourself in a part of Europe with little access to casinos 24 hours a day, as long as you have decent internet service, you can play your favorite gambling games whenever you like thanks to online casinos.

The biggest casinos and 24 hour casinos do not always go hand in hand. Europe definitely has its fair share of both options, but the more world-renowned casinos typically have daily operating hours. That’s not to say that you can’t find hundreds of smaller options throughout Europe that offer their services 24 hours a day, seven days a week.
