Why Choose the Best Online Casinos for Real Money From Our List?
Our best real money online casinos list will take you back as it stands out from other run-of-the-mill catalogs in this massive gambling industry. Once you place your confidence in our nominations, you will find nothing but the most honest and reliable information updated frequently about a plethora of online casinos. So, get into the meat of the following part to explore our list.
All Casino's Databases and Information Are Updated Continually
We always do our best to bring the most accurate information to our users; that's why we never ignore the casinos which we have reviewed once the process is complete. Instead, we always conduct periodic checks and re-evaluations to avoid missing any details that could impact the player's experience.
However, we have more than 1000+ online casinos in our database, so re-evaluating all platforms would take a huge amount of time. As a result, the most prominent platforms that earn our preferred spot on our homepage are prioritized by us to be re-evaluated on a regular basis to ensure the information on these casinos is always up to date and correct.
On the other hand, some platforms that show illegal activities and are often accused of scamming users will be at the bottom of our rankings. Because of its low ranking, we treat them as our least concern and we never recommend our players to consider. As a result, we rarely update this list.
In addition, we also look for platforms that do not fall into the first two groups. This does not mean that they are a bad online casino, just that they have not yet gained an excellent rating from us. However, they still have their own niche of players, and that's why we'll still run regular tests on these online casino sites, just less often than the leading groups.
To improve our reviews' accuracy and update ability, we also receive data contributions from the very casinos we test. That's to make sure our customers are always provided with the latest. But, of course, we only apply these changes to our analysis after the information has been fully verified.
Dedicated and Independent Team of 20 Reviewers
To create a reliable and updated source of information for gamblers, CasinoMentor refines a long list of experts for the most competent and passionate to accompany the team on the long way. This explains why many impersonal casino reviews are conducted and assured to be hot and freshly baked every day.
The team focuses on adding, editing, and deleting out-of-date content that is no longer useful for gamblers all year round. We are proud to be an independent team committed to providing nothing but valuable and trustworthy knowledge only.
100+ Testers from Five Continents
It takes a lot of time to test all the best online casinos for real money, especially when most are from many different countries and territories. Therefore, our group of over 100 local testers will dive deeply into players’ interests at an online site, including the legality, banking service, language support, as well as getting the latest news and trends at hand to keep our reviews more informative and reliable.
Our Mission: Create a Fast and Reliable Source of Casinos’ Data
If a review site is not updated rapidly, the information offered will no longer be exact and practical for players to make full use of. Eventually, players will no longer return to that site to read other articles, resulting in a considerable decrease in casino sites’ traffic and players’ confidence.
“Concise and informative” - our team makes every effort to make existing content trustworthy and helpful by applying dozens of criteria to the reviewing processes. These essential steps concern Bonuses, Banking, Customer Support, and Game Selection, the most sought-after by players.
How Do We Evaluate the Top Online Casino?
You know what, picking the right online casino for real money is a lot like choosing a home to stay in. You can’t just agree on buying a house because it looks okay and has all the areas for basic needs. Instead, you will check for the quality, the size, plus many other things, even if it fits your budget.
Understanding the hardship of the evaluation process, the CasinoMentor team decided to do something about it. We are a team of casino experts with collective experience, dedicating to equip you with the best online casinos for real money by setting specific criteria for the right one. We also score these factors, shown by the overall ratings and ranking on our website.
It is always necessary to find a casino with the highest standards in the gambling industry, along with assessing that site's quality to make sure that it’s not rigged. Based on our experts’ research, we listed below the most crucial criteria for your convenience.

The Size of User Complaints
The way operators treat players significantly affects their gambling experience. Therefore, this factor is carefully considered by us to ensure that all players are treated fairly. We often rely on the percentage of players giving negative feedback out of total customers to evaluate the quality of a casino's service.
This approach demonstrates its suitability in helping us to treat casinos more fairly, regardless of their player traffic. Of course, it would be unfair to the top platforms that we lower their ratings as they have a lot of complaints from players, which is quite understandable given that these casinos have such a larger number of players than the rest.
The Fairness of the T&CS
In addition, the T&Cs category also determines whether players can be treated transparently. These terms and conditions must all be reviewed and agreed to by the customer before placing a bet with real money, so if one of them affects the user's interests, they have no choice but to accept this.
Some unfair terms and conditions that we often encounter at unreputable casinos include the application of withdrawal fees, high monthly account management fees, high deposit limits, low withdrawal limits, low jackpot wins limits, prohibition of certain betting strategies when playing with bonuses, or always require a certain balance in the client's account and do not allow the client to withdraw the entire amount from the account.
To prevent that from our players being taken advantage of, we always double-check the fine print to make sure they don't include any details that could mislead or cause damage to players in the process of gambling. If so, we'll warn you about this in advance in our review.
Casino's Revenues
This aspect concerns the operator's solvency; therefore, it affects the safety of an online casino in paying bettors. For example, if a casino has a steady and high turnover, it will have enough budget to cover big winning players.
On the other hand, platforms that do not show a favorable business process, with low user traffic, will face many obstacles in paying out big wins to gamblers. Most likely, non-transparent operators will unreasonably accuse players of violating their terms and refuse to pay players’ winnings money.
Casino Game

No one can be happy if the real money online casino does not feature the game titles they prefer. Therefore, game variety is equally essential as trustworthiness. The more games a casino can accommodate, the better the overall player experience will be.
The best casino should team up with leading game providers such as Microgaming, Netent, Playtech, etc. Besides the massive library of slots and table games, those providers also implement a great Return To Player ratio into their products, ensuring value to the players while keeping consistent fairness across different genres.
In addition to having a great game variety, the best online casinos for real money must have adequate quality in their catalog. We would rather recommend a casino with 500 solid, high-quality games than ones with thousands of mediocre games.
Customer Support

We honor those online casinos featuring common channels such as live chat, email, and telephone support in our evaluation process. By utilizing these contact methods, players can reach the support team and solve their inquiries in a heartbeat. The best online casinos for real money must pass our test for customer services. There are a few keynotes we use to rate a casino’s customer support, such as:
- Does their email respond within 24 hours?
- How fast is the live chat?
- Do they have an intensive FAQ section?
- Is their telephone channel available? Is it toll-free or not?
- Do they have support over social media channels?
The best online casino should have the answer to all the stated questions above. Based on the availability, we can easily give a score to any online casino.
Banking Methods
We prefer the casinos that feature many trusted banking methods such as Visa, MasterCard, and virtual wallets, with acceptable transaction times for withdrawals and deposits. In addition, a safe casino needs to ensure the utilization of the latest encryption to prevent hacking, stealing, selling, or trading sensitive information from unauthorized parties for any purpose.
Casino Testing Agencies
A fair casino should be approved and tested by independent testing agencies such as eCOGRA, iTech Labs, and GLI. These agencies perform technical audits of all games and produce RTP reports showing how much money is returned after winning. More importantly, they test the random number generator (RNG) to ensure that the game results are unpredictable and randomized, preserving the integrity of casino games.
Casino Awards
Casino Awards are not applicable if the casino did not perform well. These awards serve as recognition for excellence across the online gambling industry. We recommend you to play at the casinos that hold these awards:
- Global Gaming Awards
- The EGR Awards
- The IGA awards
- The Global Regulatory awards
Each casino needs to outperform other competitors regarding the number of high-class vendors, mobile apps, games, social responsibility, and so on to earn these awards. Winners of these titles will be recognized across the community as a safe and trustworthy site to play.
How We Categorized Our Casinos
As soon as you arrive at our site, you will immediately find a long list of top online casinos for real money on display. Have you ever wondered how these sites are categorized? Below are three of our main criteria:
Casinos Are Tailored to Player’s Location
If you are looking for a legal casino to play in, you can choose the country you are residing in. All the suitable online casinos will be instantly displayed on our list based on their local popularity. Hence, each area will have a different result, and you won’t have to search manually for the available casinos anymore.
Accepted Deposit and Withdrawal Options
When it comes to playing for real money, it is inevitable for players to make banking transactions with usable currencies and methods. Therefore, to save time, our system will filter out all the online casinos that meet the player’s needs. As a result, the system can help them avoid monetary issues and set out on their gambling adventure as soon as possible.
Supporting Languages
Language is also one of our priorities. Not all the best online casinos for real money can be displayed in different languages. Thus, players can choose which language they can understand and filter out all the online casinos that use the selected language. Once the language barrier is lifted, players can easily access the casino site and fully utilize its facility.
