Casinos, casinos, casinos everywhere. But, some of them are better than others. Are you aware of which are considered the biggest casinos in the world and why? Which brands can be characterized as the most popular and reliable?

The answer isn’t definitive as the market changes daily, so a previously leading online casino may fall from grace. Still, in general, we can give this title to a gambling site that has stood the test of time, owns a trustworthy license, offers attractive promotions, features a full suite of games and maintains an honest relationship with its players. The latter refers mainly to paying players without delays and treating them with respect at all times. Let’s find out which casinos stay true to those attributes.

    What is the best casino in the world?

    Of course, there isn’t just one casino that could claim this accolade. Personal preferences always get in the way of this leisure activity, so the answer to ‘what is the best casino in the world’ depends on which casino expert you ask.

    However, as we mentioned in our introduction, we can define some characteristics that, in general, constitute a great casino. We will present them in more detail:

    Time-lasting Brands

    There are casino brands that have been operating since the beginning of the century. In an industry where competition is huge and staying afloat requires budget, experience and innovation, standing the test of time is a principal accomplishment. Especially when the casino is bolstered by tons of positive reviews instead of piles of complaints that we are used to seeing in player forums.

    Trustworthy License

    Being licensed by a reliable regulator such as the UKGC or MGA certainly elevates the status of a casino. The same stands for having obtained local licenses in regions like Sweden, Denmark, Italy, Greece or Canada. The above strategic move is made by the biggest casino companies in the world that desire to go the extra mile in terms of compliance and are also ready to fulfil their obligations towards the country they enter by paying local taxes.

    Biggest Casino Bonuses

    Players willingly give away their nice money, so casinos should come up with something to return the favor. A casino that respects its players needs to feature attractive promotions, which shouldn’t lack quantity or quality. Whether the casino puts more weight on its welcome bonus or loyalty promotions, it’s totally up to them. However, they shouldn’t neglect either new or existing players and reward them with the best casino bonuses possible.

    Full Suite of Games

    What is a casino if not its games? The best world’s online casinos should have a library of 2,000 games: from slots and table games to lotteries and scratch cards. They should partner with premium software providers. Finally, the games should be provably fair and audited by third parties.

    Honest Relationship with the Players

    We saved the most crucial factor for the end. An honest approach is everything in the casino world online and without it, no brand will manage to succeed or even survive for long. The casinos should stick to their promises. If, for instance, they have declared to process your withdrawal within two days, they should do so and not try to find excuses with double checks and excessive verification requests. This is just an example of how gambling sites should operate to gain the trust of their players, who should feel that the casino doesn’t try to cheat them.

    How we rank the biggest casinos in the world?

    ranking-icon-transThe characteristics mentioned above can work as signs of credibility when you visit a casino. Still, there are also solid metrics that can reveal which sites are indeed the biggest casinos in the world. Let’s check some of the rank criteria:


    Total Visits – Traffic Share

    Online casinos are just like any other internet site; their traffic can be measured. Although not all visitors end up registering and becoming a player at the casino, the number of total visitors per set period (month, year, etc.) is a strong indicator of the casino’s popularity. You can find your casino’s traffic by visiting tracking sites like Alexa or Semrush.

    Number of registered players

    If a casino site manages to attract a significant number of visitors, it should be able to convert a large percentage of them into depositors, meaning players. The biggest online casinos in the world attract millions of players; for example, LeoVegas AB Group had almost 2 million players depositing money in 2021. Where can you find those numbers? In the reports that online casino groups publish annually, where they state their milestones during the previous year.

    Biggest casino in the world by Revenue

    Naturally, online casinos with many players have a high revenue generated by their losses. To use again, the example of LeoVegas, the Swedish gaming group, managed to amass more than €391 million in revenue in 2021. For the same period, 888 Holdings grossed €980 million (online casino, sports betting and poker products combined). These multi-million amounts are pretty convincing that those two casinos are definitely among the biggest casinos in the world by revenue.

    Year of Establishment

    As we have stated before, the launch date of a casino plays an important role in how we perceive and rank it. It isn’t the same to evaluate a casino founded in 2000 and one that emerged in 2020. Given that online casino sites come and go so often – companies arriving with big plans, only to disappear a few years later- it is considered a great success to stay around for decades.

    Listed in the stock market

    The biggest online casinos in the world are publicly traded on the largest stock exchanges, such as the London Stock Exchange or NASDAQ. Their parent companies are listed on a given stock exchange to be more accurate. Major casino owners like Kindred Group, LeoVegas AB or Entain PLC have been listed in the London or Stockholm Stock Exchange markets, which means they have little room for malpractices or fraud.

    Which parts of the world have the best online casinos?

    Online casinos have ‘stretched their legs’ practically everywhere in the globe and have become available in almost every little tiny corner of the world. But, of course, some markets stand out more than others and include some of the world’s best casinos.


    european-casinosThe European nations have a long history and culture of money gambling. Europe is a heavily regulated region having the most extensive market size and gross gaming revenue in the world. The United Kingdom is by far the largest and most profitable market on the continent, while other significant markets are Germany, Italy, France, Sweden and Spain. It’s safe to say that if you are after the best casinos in the world, you will find the majority of them in Europe.

    North America

    north-american-casinosThe fastest growing online market in the world is North America. The legalization and regulation of online gambling in the region’s two largest countries, the United States and Canada, have brought endless opportunities for online casino companies in the last few years.

    Namely, in 2021, the industry set new revenue records in most US states where online gambling got regulated. Still, the fact that the two countries haven’t designated a centralized supervising authority complicates things as each province (Canada), or state (USA) has its local rules. Therefore the presence of the best world online casinos in these markets becomes a tricky puzzle. Some of them choose to enter only regulated environments, for example, 888 Casino in New Jersey, but most of them decide to avoid the market altogether.

    Asia – Pacific Region

    This market has a very diverse picture. You have rapidly growing markets like the Philippines, while in others, online gambling is outright forbidden, such as China and the majority of the Muslim countries. You also have markets where the image isn’t clear, like Australia, where foreign gambling sites are banned, but domestically based online casinos can offer their services abroad. Depending on the country you reside in, you may be able to play in some of the biggest online casinos in the world, such as LeoVegas in India.

    Are the best online casinos worldwide available in all countries?

    Unfortunately, you cannot access the best online casinos worldwide from anywhere. Web-based casinos are heavily dependent on the local gambling laws of each country in which they express interest in operating. So, they secure their presence only in those markets where they have acquired licenses from the local regulatory authorities.

    Most online casinos are restricted in at least a few parts of the world. As a result, they don’t include those countries in their registration form. The world’s best casinos pay special attention to being fully compliant and don’t offer their services to markets that aren’t allowed to. The reason? They don’t want to get blacklisted by the local regulator and damage their reputation and prospects for acquiring a license in that region. You can check out which online venues are available in your country and avoid losing your time on restricted sites through our reviews.


    If we are talking about gaming content, that would be Videoslots, which partners with almost every iGaming provider known. If we care about market presence, that would probably be 888 Casino, licensed to operate in many parts of the world.

    There is no definitive answer to this question. Depending on what you value the most -trustworthy license, large gaming variety, fast withdrawals, honest approach by the casino- your choice would differ from another player’s. Of course, it would be great to find a casino that combines all these elements.
