Helping our visitors find top online casinos is one of the main missions of Casino Guru. Having reviewed over 7,000 real money casino sites – literally every single casino site we've been able to find – we know what to look for when deciding which gambling site deserves to be called one of the best online casinos in May 2025.
In this part of the page, you can read about how we review online casinos, our casino review team, how to use Casino Guru to find the best casino for you, and much more.
We meticulously and methodically review each casino site listed on our website – whether it is one of the top 10 online casinos or one of the worst ones – with a focus on fairness and safety.
We consider these the most important factors influencing the quality of online casinos, because we believe that players should be able to play real money online casino games and withdraw their winnings without experiencing issues like blocked accounts or declined withdrawals. That's what top online casino sites can offer and bad ones cannot.
That's why you see the Safety Index displayed next to each casino listed above. This is our safety score, which we calculate for all online casinos we review. It is based on a number of factors, such as:
Basically, we look for anything that could make your online casino experience unsafe or less enjoyable. The higher the Safety Index, the more likely you are to be able to enjoy real money online casino games and be able to cash out your winnings from the casino without running into issues which might be common at online casinos with a low Safety Index.
Our in-depth casino reviews and recommendations would not be possible without the hard work of our independent casino review team. It is this team's sole responsibility to learn everything there is to know about each casino site they review.
We use the information collected by the review team to calculate each casino's Safety Index, which allows us to recommend safe online casinos to our visitors.
It is part of Casino Guru's mission to review and rate all available real money online casinos. We do that by consistently looking for new casino sites and doing a detailed review of every single online casino we discover. Thanks to this, we can consider all available casinos and select the best ones when creating and updating this list of best online casinos.
As you can imagine, this takes a lot of hard work. We currently have more than 6,000 online casinos in our database, all of which have been through our methodical process that evaluates the casino's qualities, with a focus on fairness and player safety. We add tens or hundreds of new casinos to our database and continuously revisit existing ones to keep our information up to date.
All of this is done by a dedicated team of more than 15 casino specialists led by Matej Novota, who has been part of the Casino Guru team basically since the beginning and has helped set up and fine-tune our casino review methodology.
Matej and the rest of the team go truly in-depth with each online casino they evaluate. They check each casino's website, thoroughly read the Terms and Conditions to uncover and unfair rules, evaluate player complaints, check licenses and company information, and go through countless other steps required to learn everything we need to know to evaluate an online casino and decide whether we are going to recommend it to our visitors or not. Based on this, we calculate each casino's Safety Index and decide which online casinos to recommend and which not to recommend.
As already mentioned, we are constantly on the lookout for newly opened online casinos. On top of that, we periodically update our existing reviews, so that we keep providing up-to-date information to our visitors. In the table below, you can see an overview of what has changed in the last few weeks.
| From | To | New casinos added and reviewed | Existing reviews updated | Safety Index increased by 0.5 or more | Safety Index decreased by 0.5 or more |
|---|---|---|---|---|---|
| April 14 | April 20 | 33 | 150 | 21 | 70 |
| April 21 | April 27 | 36 | 153 | 324 | 179 |
| April 28 | May 4 | 32 | 119 | 42 | 63 |
| May 5 | May 11 | 43 | 118 | 79 | 55 |
| May 12 | May 18 | 40 | 119 | 169 | 94 |
On top of our expert evaluation of each online casino you can find on this page, you can also take a look at the user feedback scores when selecting a casino to play at.
Members of the Casino Guru community can submit their own reviews of online casinos, rating them on a scale from 1 to 5. Based on the submitted user reviews, we calculate an overall User feedback score that ranges from Terrible to Excellent.
Reviews from other casino players can be a great resource when selecting the best online casino for you. They can give you an insight into what other players experience while playing, including any positive aspects or significant issues they have encountered.
With more than 6,000 real money online casinos in our database and the gambling market steadily growing according to Statista.com, casino players from many regions are spoilt for choice. Competition between casinos is, of course, generally good for players, but the sheer number of them can make it difficult to choose the best option. So, how do you find the best online casino for you?
You can start your search by checking out the list of top online casinos above. Based on our expert recommendations, the best casino sites are located at the top of the list. These have received the approval from our in-house expert review team and will be a good fit for most players. However, if you're after something specific, we suggest using our filters to tailor the results to your preferences and find the ideal match for you.
Above the first listed casino, you can see four tabs that can also assist you in your search. These are quick shortcuts to different lists of top online casinos, which you may be interested in:
On top of the tabs listed above, we have an advanced system of sorts and filters, which will allow you to fine-tune your search for the best online casino with real money games. In this part of the article, we will give you an overview of how to use the sorts and filters on our casino list to find the best option for you.
No matter which tab you're in, you can see several sorting options available. These let you reorder the list of online casinos based on different criteria. For example, if you wish to see the best online casino sites at the top of the list, select the 'Recommended' sort.
Other sorts that you can apply to change the order of the casinos include 'Recently opened,' 'Recently added,' or 'Highest Safety Index.'
As we've mentioned in the previous section, we've also designed a broad selection of useful filters that you can use to narrow down the top online casino options based on your specific requirements. Here's an overview of some of the filters available:
If you are looking for an even easier way of choosing the right casino for you, you can use our casino selection helper tool linked above, just under the list of best online casinos itself.
By answering three simple and quick questions related to bonuses, games, and age of online casinos you prefer, you will be presented with three top casinos that meet your criteria. Then it is just a matter of selecting the one that looks best to you or going back to the list if you realize that you would like to see more options after all.
Whichever of the displayed top casinos you choose, you will find a casino that treats players well and is recommended by our casino experts. Each of them has a unique feature or advantage listed in the tool to make your final decision easier.
For now, we have focused on finding the best casino to play at. However, it is just as important to know which real money casino sites you should definitely avoid, as playing at a slightly subpar site is still much better than playing at one that is likely to use unfair practices or even outright scam you.
First-and-foremost, you should take a look at our casino blacklist. If a casino appears on it, it must have done something especially serious that goes against the principles of fair and safe gambling. This is a clear sign you should stay away from it and choose a different one instead.
Casino sites or companies running them can be listed on a blacklist for a multitude of reasons, ranging from potentially tolerable reasons to undeniably unacceptable ones. If you take a look at our blacklist, you will find a range of issues we discovered:
Additionally, take a look at the casino's Safety Index here on Casino Guru – our metric for evaluating the fairness and safety of online casinos. It is a good idea to avoid playing at casinos with a Low or Very low Safety Index.
If you'd like to register and start playing at a real money online casino, the process is usually pretty straightforward, although it tends to differ from casino to casino. In general, here are the steps you should follow at most casino sites:
Cashing out money from your casino account is usually pretty straightforward, perhaps with the exception of your first withdrawal. This is because many casinos start the KYC process when they receive your first withdrawal request. If that happens, cooperate with the casino and submit the required documents for verification.
Most commonly, you will be able to withdraw funds using the payment method you also used to make a deposit. For example, if you deposited using your Mastercard, your withdrawal will be processed using the same card.
However, you may come across some exceptions. For example, the payment method that you used to make a deposit may not be supported for withdrawals. In such a situation, you will likely be required to verify an alternative payment method. Online casinos do this to ensure that the payment method truly belongs to you.
The withdrawal process is generally very similar to making a deposit. To request a withdrawal, you usually have to go to the Cashier section on the website of the casino. Once there, find the withdrawal section, enter the amount you wish to withdraw, and confirm the request. Some online casinos may ask you to enter your password, but as long as your account and payment method are already verified, that should be all.
The selection of slots and other types of real money casino games is an important factor to consider when selecting a casino to play at. After all, gambling should first and foremost be fun, and the games we play at online casinos greatly influence this aspect.
Luckily, many modern online casino sites have vast libraries of casino games on offer, ranging from slots, through table games like blackjack or roulette, to less frequent options like crash games or keno.
Here is an overview of the most common and popular types of casino games:
As you can see, you should be able to find enjoyable games at any of the top-rated casinos listed above. The types of available games are listed right next to each casino, and information about game providers is available in each casino's review.
If your preferences are specific, you can use our filters to limit the selection of displayed casino sites in the list to those that offer a certain type of casino games (such as slots or roulette) or games from a specific game provider (such as Pragmatic Play, NetEnt, or many others).
If you are new to online casinos, it is important you know how real money casino games work when playing online. Slots, roulette, blackjack, and other popular types of games each have their own specifics, but there is one underlying aspect they have in common – the casino has an edge.
Casino games are configured to give the casino an advantage (also known as house edge), which ensures that casinos stay profitable in the long run. You can still win; however, over a long period of time and with a large number of players, the casino will almost certainly be profitable. In short, you are virtually always playing at a disadvantage.
There are two main mathematical characteristics of any real money casino game:
We believe that knowing this will help you make better decisions when it comes to casino games, as it doesn't give you unrealistic expectations of winning money on a long-term basis. And, as we always say, gambling at online casinos should be about having fun, not about making money.
While we focus mainly on real money online casinos, there are other types of gambling available online. There are gambling sites that focus on sports betting, poker, and other gambling genres that are not necessarily played against the house, like traditional casino games are.
Many casino sites combine multiple types of gambling together, resulting in a website with an offering suitable for a wide audience. Also, some players prefer playing casino games for free, without the risk of losing any money.
Many players are interested in online casino bonuses, as they provide them with something extra alongside their real money deposit or even allow them to play for free. If this is also your case, you can find a bonus offer listed next to most of the top online casinos above.
The most common casino bonuses are probably welcome or sign-up bonuses, also known as bonuses for new players. These promotions are intended to encourage players to set up an account at a new casino and start playing there for real money. Typically, they come in two forms – no deposit bonuses and deposit bonuses.
No deposit bonuses are especially popular among players, as they let them try a new casino site without the need to make a deposit and risk their own money. Deposit bonuses, on the other hand, are more widespread and give players extra funds or free spins after making their first deposit.
If you want to learn more about the bonuses offered by any of the casinos on our list, click 'Read review' and proceed to the 'Bonuses' section of our review. There, you'll find all the available bonuses offered by that casino, together with their Terms and Conditions, which will help you choose the best offer for you.
Alternatively, if bonuses are your main priority, it might be better for you to proceed to our list of casino bonuses and browse offers from all online casinos. If you're looking for something more specific, you can refine your search using our selection of filters.
Playing real money casino games online can be fun, but it can also have a negative impact on people's lives. Besides the possibility of losing money, gambling addiction can be extremely dangerous, which emphasizes the importance of safer and responsible gambling, such as setting a budget and limits in advance, as well as looking for help if you gambling habits start getting out of hand.
Our responsible gambling section contains a plethora of information on the topic, allowing you to stay informed on how to gamble safely, where to look for help if needed, and many other topics. If you feel like you are at risk, don't hesitate to talk to a professional.
Here are some quick safer gambling tips taken from our safer gambling article:
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).
