What is the biggest online casino in the world?
This is is a question easy to ask and tricky to answer.
That is why we have deployed an army of online casino experts. Their mission was to check and examine a great number of online gambling venues. Once they do that, their task becomes reviewing these handpicked largest online casinos based on numerous strict criteria.
Before displaying a venue on the top 10 online casinos in the world list, we had to check the licences, Customer Support, banking methods, and content. In addition, we had to make sure each venue sported the most popular online casino slots and sought-after titles. After all, it would be a shame to have the top 5 largest casinos in the world in front of you, and they lacked the content you want. And not every big online casino deserves to be honoured as one of top 10 online casinos.
It took a lot of time, effort, and dedication to compile relevant standards and lists before unveiling the top 10 best online casinos in the world before you. We at Best Casinos choose only the most distinguished and finest casino sites for our readers. Our biggest online casino recommendations are honest and unbiased.
Discovering the biggest online casinos in Europe & World is time-consuming and requires dedication. Here is a list of what we deem the best and biggest casino sites in different categories for impatient players.

We want you to have the most quality casino content, so we have done all the heavy lifting instead of you. What follows is a compilation of key touchstones that we considered in finding the largest online casinos in the world. These include:
Of course, there are other factors to include in your search too. For instance, target markets might not seem that important. Still, they certainly are once you realise you are hunting for the top USA online casino or the largest casino companies in Europe. There’s also the question of currencies, support, and bonuses to think about, as you want a safe experience before anything else. So, it seems that the biggest casino in the world is nothing if it’s not the safest site out there.
The aspect you need to look at before all others!
Legitimate online casinos are checked above all based on their licenses. So, we need to address the elephant in the room immediately. Having at least a couple of distinguished regulatory bodies makes a good online casino. But having 3+ strict supervisory organs is optimal for the biggest online casinos.
The most reputable and rigid monitory firms are the UK Gambling Commission (UKGC), the Malta Gaming Authority (MGA), Gibraltar Betting and Gaming Association (GBGA), and the Swedish Gambling Authority (Spelinspektionen). Many others like Alderney, Ireland and Curacao exist, but these above are known as the definition of strictness. Only the largest online casinos possess their licences.
You can check every online casino’s licensor on the bottom of the homepage. Simply scroll down, and you will see the stamps of approval.
What’s more, the best international online casino site takes care of your safety through other means of protection. One of the precautionary measures is the utilisation of the SSL protocols. Secure Socket Layer encryption makes sure all your financial transactions are intact.
They safeguard your deposit/withdrawal request by establishing a secure connection between you and the operator.
Likewise, a reliable and trustworthy online casino website posts its audits for the public to see. Some of the most eminent agencies are eCogra and TST. These independent auditing bodies check the regulation of all activity at the casino premises.
Moving on to the main part of the list, here is a visual representation of what we deem crucial in the process of recognising the world’s largest online casinos.
All the biggest casino companies know that it’s important to have a plethora of casino suppliers by their side. Sure, sticking with one slot provider can be a good tactic for some casino operators. However, it is usually favourable to boast at least several developers support the content library.
The main reason behind this logic is the diversity of styles. While players usually prefer a particular kind of visuals, they like to shift to others from time to time. For example, you might be into fantasy slots, but you can get tired of them. Perhaps then you’d like to give branded video slots a shot. Or animal games might be up your alley. At the end of the day, it is good to have a choice.
From a technical point of view, the gameplay and mechanics of those titles should be user-friendly. What we mean by this above all is a solid payout percentage (RTP). RTP is the Return to Player.
Our team has compiled comprehensive articles about the highest-paying slots from various providers. We covered:
If you want more info about the best games with high RTPs, check out our top RTP online slots lists found among our articles. Additionally, it’s also nice to check out different approaches to the same theme.
Therefore, you can play Asian or Egyptian slots from Realtime Gaming (RTG), NetEnt, Play’n GO or Microgaming. And it’s just one instance. You can experiment with a litany of titles if your favourite online casino partners with multiple manufacturers.
Lastly, let’s not forget jackpots. Progressives are a burning topic, especially among high limit players. They take some time to accumulate, but when they do, they pay out immensely. Progressive jackpots are made for patient players. Big online casinos should offer at least a dozen jackpots.
We are not concerned only with slots. We at Best Casinos are aware that some players might be fonder of table and card games, as well as live dealer tables.
The same rules apply to live casinos. A live dealer lounge is an ever-welcome guest at all top online casinos. In today’s fast-paced world, few people have time to go to a physical casino. Instead, they seek an ultra-lifelike, authentic live gambling experience from home.
At the largest casino companies, players can play Live Roulette, Live Blackjack and Live Baccarat, to mention a few. Big software suppliers like Evolution, NetEnt and Playtech are the most famous and prolific live dealer providers.
A frequently overlooked factor of a successful online casino is a good customer support team. But what does “good” in this context mean? To start with, the client service team should be available 24/7.
In other words, you get round-the-clock service and assistance at all times. So, if an online casino’s customer service operates 24 hours a day, seven days a week, it’s already a good start.
Besides, various communication methods are also typical of a big online casino. The most popular option right now is Live Chat. The live facility is hot with players because it provides instant help and is hassle-free. It is simple and quick, and it solves issues immediately. Furthermore, the second most popular support option is the phone.
The biggest online casinos offer their international toll-free phone numbers. Moving on, every online gaming brand should cater to an e-mail service. Some players prefer written correspondence. A comprehensive FAQ section is always welcome, as well as an online enquiry form. The latter is available directly on the website; you need to fill it out with the required info.
Let’s be honest, promotions and bonuses are what first attract your attention when checking out a casino.
How cool is it to see that the casino you are considering offers a no deposit bonus?
That means you just need to sign up, and you’ll have free cash to spend on your favourite games! There are also first and second deposit bonuses at hand. All of these are reserved for new customers only.
Nevertheless, existing clients are not left hanging. As a regular player at a big casino, you can benefit from daily deals and exclusive promotions.
A large number of casinos hosts daily promotions. They have a special deal surrounding a specific game or banking method on a particular day. Here on this website, you can find a definitive list of the best daily deals in the industry. You can play any day of the week and get free stuff, such as comp points.
On the other hand, some casinos are keener on short-lived campaigns announced from time to time. Luckily, Best Casinos professionals keep their eyes peeled and post the ongoing promos regularly.
So, a big online casino has to have attractive promotions and bonuses.
The next thing on our list concerns finances. A necessary part of your real money online casino journey is banking. To gamble for real money, you have to have a means of financial transactions. It depends on a few criteria that would suit you, and your casino of choice should offer it.
At the time of writing, the most popular payment method is an e-wallet. With this banking option, you get fast and easy transfers where additional costs don’t ensue.
Great examples of popular e-wallets options in online gambling are:
Apart from electronic wallets, mobile payment options are also quite popular. The most popular mobile casino payment options are:
Moreover, selecting prepaid vouchers and various bank transfers is a green light for a large casino.
Finally, you’d likely want your online casino to let you utilise your preferred currency. Just imagine showing up at a top 10 casino in the world, and it didn’t have your native currency! We can agree that that would be unacceptable. Nowadays, in addition to traditional national currencies, the biggest casinos accept cryptocurrencies like Bitcoin and Ethereum.
Last but certainly not least is the technical adaptability of the casino. Every self-respecting online casino boasts optimised performance across all platforms.
Times have changed over the years, and fewer players use the desktop version. The world has gotten faster, and most people don’t have the time to sit down before a computer. Instead, they like to enjoy top mobile casino sites on an Apple or Android phone.
A modern player likes to be able to play on the go. Therefore, all the biggest online casinos in the world are mobile-friendly. That means easily accessed on smartphones, tablets and Blackberry phones.
In most cases, you are not required to download any software. Instead, you can simply load the homepage of the casino in your mobile browser.
And those are the basic things that make top mobile casino sites reliable and worthy of your time.
Web-based operators have been steadily growing their libraries over the years thanks to the popularity of such games. Today, digital gambling is one of numerous online punters’ favourite pastimes, and they all enjoy thousands of modern casino titles.
But certain venues stand out from the rest. Their defining characteristics might include unique designs, a charming backstory, or even special payment methods. But our favourite characteristic is a massive portfolio with thousands of games. And here is where the top 5 largest casinos in the world come into play.
Below is a list of five casinos with the largest content offers on the internet. We have no doubts that you are quite familiar with them, especially with the top-rated biggest casino in the world.
NUMBER OF GAMES
Videoslots passed its 5,000th game mark long ago and is slowly building towards its 6,000-title target. We are confident we will not have to wait long before the operator reaches it – as it gets content from the biggest casino companies around the globe!
Moreover, the rest of the venues follow suit, enriching their offers and filling their lobbies with premium titles and releases every day.
Let’s sum up what makes the biggest online casinos on the planet. The most trusted online casino will have a checklist that at all times needs to be complete.
First and foremost is safety. Safety entails the likes of licensing, encryption protocols and auditing services. Second is the partnership with numerous industry-leading software providers. As a result, the third factor comes, which is an ample selection of diverse games. This portfolio should encompass classic and video slots, table and card games, jackpots, live casino tables and speciality titles.
Next up is banking. A plethora of diverse payment methods should be at your disposal always. Furthermore, in times of wonder, a good customer service team should be at hand. A helpful agent of a big casino will pick up the phone 24/7 and answer your queries round the clock.
Taking a walk on the fun side, it’s always great to see a fine selection of rewarding promotions and bonuses. But ultimately, everything mentioned above should be available on mobile, as well.
So, it all comes down to these 7 factors that make the biggest online casino in the world.
Unfortunately, you will find few top-rated online casinos USA on the list of the largest online casinos in the world because they rarely offer thousands of games. Instead, they focus on quality – and as America grows as a gambling market online, its scope will grow as well.
US-friendly casinos offer a plethora of perks to their players, but no casino can beat Miami Club casino’s offer. Miami Club is a WGS Technology-powered sister casino to Red Stag and Black Diamond. Besides Miami Club, players also enjoy visiting Uptown Aces for its bonus offers, Drake Casino because it has a great loyalty program, and Wild Casino, which allows punters to use cryptocurrencies.
The main benefit is certainly the massive content library. The largest online casinos offer thousands of releases, so there is virtually no chance to get bored at the website. Moreover, with a large number of games usually comes a great quantity of bonuses. Moreover, if the site boasts a big casino lobby, that usually means it is working with trusted suppliers, so you do not have to worry about safety and fairness.
As one of the biggest gambling markets, Europe is home to a staggering number of online casinos. However, the biggest gambling site in Europe (and the rest of the world, probably) is Videoslots. Videoslots features over 5,500 casino games and a superb promo program with countless weekly tournaments.
The largest online casino jackpot win ever happened in 2013 when a player from Finland won over €17 million by playing Mega Fortune progressive jackpot. The total sum that the player won was €17,861,800.
No deposit bonus offers are a popular form of promotions on gaming websites. Punters enjoy using such deals when they first enter the casino. But, as you know, this is a deal reserved for newcomers – and the biggest online casinos do enjoy accommodating their potential customers. So, yes – the biggest online casinos in the world do offer no deposit bonuses and promotions.
In terms of content, Videoslots is the biggest casino in the world. This web-based operator boasts one of the biggest content libraries on the internet. However, in terms of outreach and market presence, it is 888. This brand is present on all continents, with business operations in most countries. So, depending on the form of the question, we could say that both Videoslots and 888 are the biggest online casinos in the world.
No, the biggest operators are not available in all countries. Web-based operators depend on the gambling laws in each state, and laws are different in each country. So, they are present only in those markets where they’ve acquired licences from international regulatory bodies. You can check which countries are restricted with each venue which we rated and reviewed.
Videoslots, the biggest online casino in the world, caters to UK players as well. What is more, the UK is one of the operator’s primary targets, so there are always exclusive offers for players from that region. You can check which other venues with impressive libraries offer their services to players from the UK on our corresponding page.
