We made it our goal to review any online casino that exists, with a focus on fairness and player safety. Thanks to this, you can find information about virtually all available online casinos and choose from the largest selections of casino sites on Casino Guru.
Reviews of online casinos are one of the cornerstones of Casino Guru. They are conducted by a dedicated team of almost 20 casino reviewers, whose sole responsibility is to collect information about online casinos and use it to evaluate their fairness and safety.
To evaluate online casinos objectively and consistently, we have spent years developing and fine-tuning our data-driven review methodology. As a result, our team of reviewers approach each casino site the same way, which leads to reliable and unbiased data.
Casino Guru is visited by players from many countries and regions, which is why we need to provide truthful and valid information to visitors from all around the world. We work with an international team of casino testers who help us gather and verify local insights.
Focusing on fairness and safety of online gambling is one of the cornerstones of Casino Guru. Besides evaluating casinos based on these factors, we push them to remove unfair rules from their T&Cs, resolve complaints in a fair way, and stop unfair treatment of players.
Our website is visited by millions of visitors from many countries, who interact with it and provide priceless feedback about online casinos, casino bonuses, games, and much more. We use this feedback to make the content we provide to users as helpful as possible.
A casino can be great for players from one part of the world and terrible for other players. That’s why we’ve created a custom casino ranking relevant for players from United States, which consists of our evaluation of each casino on a global level, as well as custom factors important for players in United States.
Complaints tell us how each casino treats its players. If many players complain about unfair practices of an online casino, we know that something is most likely wrong with it.
Casinos with more active players and higher revenues will not struggle to pay out big wins, so we generally consider them to be a safer choice.
We carefully read the Terms and Conditions of each online casino to determine if they are fair towards players and don’t contain deceitful or potentially harmful clauses.
If we find a casino on some blacklists, we warn our visitors and consider each of them separately to determine how we should alter our Safety Index.
Not all online casinos operate individually. Many of them are a part of a bigger group of related casinos. For these, we also reflect the related casinos in our Safety Index.
It only makes sense for us to recommend you online casinos which accept players from United States. That’s why this is the most important local factor that goes into the rating.
Not all payment methods are available and popular in all countries. We know which methods are used by players from United States and favor online casinos which support them.
It’s no surprise that people prefer playing in the language they understand most. That’s why the support of English language is an important factor we consider.
The registration and first deposit can be very tiring at some online casinos and for players from some countries. This also influences our rating for United States.
We work with testers from all over the world to make sure that we are able to recommend the best online casinos to players from all countries, including United States.
Choosing a good online casino is one of the most important steps when you want to start playing casino games for real money online. There are reputable casinos which treat players well, but there are also casinos which do everything they can to exploit them. It’s crucial that you pick a good one, which is exactly where our list of best online casinos comes in helpful.
All online casinos have a mathematical advantage against players. Casinos rely on this advantage to make a profit, but some of them go even further and use unfair practices to increase this advantage beyond the one provided by the house edge. We inspect each online casino in detail, so that we can recommend the best casinos that behave fairly towards players.
There are also other factors which go into determining whether a casino is a good choice for you. You can read more about this in our article about how to choose an online casino.
It’s also crucial for you to use your own personal information and make sure that everything you enter when creating an account is correct and truthful. Online casinos always check the identity of players when they want to make their first withdrawal (at latest), so you won’t be able to withdraw money from a casino if you use incorrect details.
The vast majority of online casinos trigger a so-called KYC (Know Your Customer) procedure when a player wants to make their first withdrawal. This involves checking players’ identity cards, passports, or other documents, so there really isn’t any sensible way to go around having to use your own personal details to gamble online.
Although casino bonuses are tempting as they give you more money to play with, they are not always the best choice. There are always rules you have to follow when playing with bonus money, which can be quite restrictive and often make it very difficult to actually withdraw money after taking a bonus. We believe that players are sometimes better off playing without a bonus than with it.
Here are some examples of rules commonly associated with bonus play:
We’re not saying casino bonuses are always bad. That just wouldn’t be true. We just want you to be aware of all conditions which are in place for each specific bonus before deciding whether taking it a good choice for you or not.
The payment methods (bank accounts, cards, internet wallets) you use to deposit money into your casino account should be yours and held in your own name. Using someone else’s card, bank account, or wallet can lead to a permanent account closure and can be used as a reason for not paying out winnings.
It’s important you understand that gambling is not a way to make money. You can get lucky and win in the short term, but don’t expect to systematically win money by playing casino games. If you get lucky and hit a nice win, withdraw your money, because you will lose it sooner or later if you keep playing. Also, remember that gambling addiction is a serious issue, so play safely and seek help if your gambling starts getting out of hand.
Casinos always have an advantage, but you can play in a smart way to minimize it and give the house as little edge as possible. Some games are better than others from the mathematical point of view, but you should always remember that you will be playing at a disadvantage regardless of what you do. You can explore this further by reading our article about games of chance.
From the perspective of safe and responsible gambling, it’s important to remember that gambling addiction has the power to destroy lives, so you should approach gambling as something that is potentially harmful. Read our article with tips on how to gamble safely and explore our problem gambling section for more information about gambling addiction, how to diagnose it and how to overcome it in case it develops.
When it comes to your choice of available online casinos, very few factors are as influential as your country of residence. The regulations of individual countries and their attractiveness for online casino operators mean that the choice of top online casinos varies greatly from country to country. Below, we will take a look at some European countries and their online casino markets.
The United Kingdom has one of the most developed online gambling markets in the world. Its gambling regulator – the Gambling Commission – is one of the most recognized authorities in the gambling world, and the UK market is home to hundreds of reputable online casinos. To learn more, take a look at our list of best online casinos in the UK. Alternatively, there are also entire websites that specialize in the UK gambling market, such as casinometer.co.uk or kingcasinobonus.co.uk.
The regulated and legal online gambling market in Italy has been opened in 2011, when the country introduced its new gambling regulations. The market is regulated by AAMS (Agenzia delle Dogane e dei Monopoli), with plans of regulatory changes being developed. Check out our list of best online casinos in Italy, or, if you speak Italian, visit Casino Guru in Italian at casinoguru-it.com.
In the past, legal online gambling in Greece has only been available through OPAP, which had a monopoly fully and since 2013 partially owned by the state. Since 2020, other companies entered the market, which means that Greek players now have more legal online casino sites regulated by the Hellenic Gaming Commission to choose from. If you are from Greece, check out Casino Guru in Greek at casinoguru-gr.com.
The Czech Gambling Act of 2017 has opened up the online casino market, which now has a number of legal and regulated online casinos for Czech players to choose from. To learn more, visit Casino Guru in Czech at kasinoguru-cz.com. Also, there are websites that focus solely on Czech legal online casinos, such as licencovanakasina.cz.
Similar to Czechia in many ways, the Slovak legal online casino market has opened up in the recent years thanks to new regulations introduced in 2019. TIPOS, a state-owned company, was the only legal option before the new regulations, but now there are more than 10 legal options for Slovak players regulated by ÚRHH (Úrad pre reguláciu hazardných hier). To learn more about legal online casinos in Slovakia, visit oficialnekasina.sk.
There is no such thing as the best online casino for everyone. Different players are looking for different things when selecting an online casino site to play at. This means that a top choice for one player be completely unsuitable for someone else.
This is why we have dedicated so much effort in meticulously reviewing all casino sites we have been able to find on the internet, as it enables us to have an option for everyone.
This list of best casino sites in 2025 is the outcome of our efforts, with casinos ranked from best to worst based on the finding of our independent casino review team. If you are looking for a quick choice, you can find the best casinos overall at the top of this page when the 'Recommended' sort is selected.
If you are looking for something more specific, you can use our advanced filtering options or read our casino reviews, in which you can find information about safety, game selection, payments, user reviews, player complaints, and many other aspects that will help you make the right choice.
Of course, you can. However, there are some caveats we need to mention.
First of all, all online casino games are configured to give the house an advantage, which means that you are always playing at a disadvantage. You can get lucky and win, but it is virtually impossible to be profitable in the long run. Therefore, if you manage to win, it is certainly advisable to withdraw your winnings.
Secondly, to be able to win in an online casino and actually withdraw your winnings without issues, it is important to select a reliable casino site to play at. That's why we evaluate the safety and fairness of all online casinos we review – to help you choose the safest and best online casino for you.
Many online casinos are safe, but many are not. At least according to our methodology and what we consider to be safe and unsafe. Some casino sites put an utmost emphasis on fairness and player safety, and some online casinos actively try to scam their players. And most online casinos fall somewhere between these two extremes.
We consider all casinos listed in the 'Recommended' tab above good and safe options for most players, with the absolute best options appearing at the top of the list. Take a look at the Safety Index of the online casinos you are considering to get an idea about their safety. The Safety Index is our safety score calculated based on the information collected and evaluated during the review process. The higher the Safety Index, the more likely you are to be able to gamble safely and withdraw your winnings without any issues if you manage to win.
In general, yes. Casino games come with a house edge, which means that casinos have a statistical advantage that ensures their profit in the long run, but that does not mean they are unfair.
Reputable casino game providers state how much a game is expected to pay out statistically, and as long as the actual long-term results approach these figures, we can say that a game is fair.
That said, there are always people trying to scam others, which means you can find online casinos with bad intentions, as well as misleading or fake games that do not pay out as much as they claim. Choosing a top rated online casino should help you avoid unfair treatment.
If you choose a big and well-known online casino with good reviews, a high Safety Index, and a large number of satisfied customers, it is fair to say that you can trust it. That said, we should always be careful when deciding who to trust, especially online.
In general, established online casinos with good reviews are safer for players, as their size and player base allow them to pay out big wins to players without issues. Moreover, their popularity also adds to their trustworthiness, as it shows that they are already trusted by many.
To find an online casino you can trust, take a look at our reviews and ratings, and choose a site with a high Safety Index. Our methodology for calculating the Safety Index takes into account characteristics that go hand-in-hand with trustworthiness.
Modern online casinos are fully optimized for all types of commonly used devices, such as computers, tablets, and mobile phones. Some casino sites even come with mobile apps that can make playing casino games on mobile devices even more seamless and enjoyable.
If you want to make sure you select a mobile-friendly option, choose from our list of best mobile online casinos.
In most cases, the payouts you can expect depend on the games you are playing, not on the casino you are playing them at. Casino games are created by companies known as game providers, who then make their games available for real money play through online casinos. If you the same game at multiple casinos, you can expect similar results, at least at a statistical level.
That said, in-game wins don't matter if the casino you are playing at refuses to pay them out. That's why it's important you select a top rated online casino to play at.
Also, we should point out that there are cases in which game providers create multiple versions of the same games, each with a different RTP and house edge. In these cases, you can expect different results at different casino sites. To make sure you are playing the best option, you can check the RTP inside the game itself.
There are many authorities that license and regulate online casinos. Some of them focus on gambling within a specific country, while other have a more global approach.
From country-specific licensing authorities, UK's Gambling Commission and Sweden's Spelinspektionen are regarded as some of the world's leading authorities with the highest standards of regulatory oversight and player protection.
When talking about authorities that focus on a wider area, the Malta Gaming Authority is perhaps the most advanced and well-known one. Many online casinos are licensed in Curaçao; however, the country's licensing authorities are not known for having standards as high as the three mentioned previously.
All that said, we should point out that license is not everything. It is a good start, but having a license from a good regulator does not automatically guarantee that a casino will treat you well. At the same time, having a license from a bad regulator does not mean that the casino will be unfair and try to scam you. There are good and bad casinos on both sides of the licensing spectrum.
Yes, they do. However, there are some things you should know. Firstly, you need to choose a reliable online casino, so that your winnings are paid out to you if you do win. Secondly, you should know that you are always playing at a disadvantage in an online casino. So, you can win and get your winnings paid out, but it is more likely that you will lose.
The casino does not decide who wins and who loses. There is a level of randomness present in all casino games. In slots, there is a random number generator that chooses a random number, which determines the outcome of the game. In roulette, this is achieved by the roulette ball, which lands on one of the numbers at random.
Each bet can win or lose, and the chances of winning or losing are generally proportional to the sizes of potential wins or losses. For example, if bet on red in roulette, you will double your bet in 48.6% of cases. If you bet on a specific number, you can win 36-times your bet, but that happens only in 2.7% of cases.
When you browse our list of top casino sites, you will see a bonus offer listed next to each site that offers one. That said, many of the listed top online casinos offer multiple bonuses. You can find those by clicking the ‘Read Review’ button, as all available casino bonuses are listed in our detailed reviews.
