We rank and review each of our top 5 online casinos according to a stringent ten tier process. This strategy allows you the peace of mind that when you look at opening a real money casino account with one of them, there is a wealth of time, research and industry knowledge supporting you in making that decision.
All casino brands must excel at the following 10 competencies:
Before we can consider praising a brand for being one of the world’s best casinos, we have to consider whether or not they have a good reputation amongst their peers and among players. Have they shown themselves to be financially sound and do they have a passion for caring for their customers?
We also look at if they are willing to be held accountable for their business practices. Casinos that apply for licenses in strict jurisdictions like the UK and allow independent regulatory bodies such as eCogra to review their fair gaming and player protection policies are more likely to be brands you can trust.
List of the most reputable and trustworthy online casinos:
Malta Gaming Authority, Danish Gambling Authority, Swedish Gambling Authority, UK Gambling Commission, Spanish Directorate General Regulation
The fact of the matter is that not all gaming software is made equal. All the top online casinos use cutting-edge technology to secure players' data and enhance your gaming experience. In addition, that ensures the casino itself is modern and visually appealing, including great features like gamification, mobile optimisation, and the ability to use the same wallet and player logins regardless of device.
The reputable game providers like Microgaming, Playtech and NetEnt allow their casino partners to run their businesses without putting the customer and their data at risk. They also intervene in cases where players feel there might be something amiss. The same is not true for less reputable game providers and hence would never be considered for our Top 5 list.
List of the most popular online casino game providers:
As we mentioned before, a casino's decision to pursue or avoid licensing in certain markets can give you insight into things like cash flow and business practices. Brands that have successfully acquired a license in the United Kingdom have submitted their business practices and financial standing to the UK government for review and received their approval.
In addition, they have agreed to abide by UK law, which is heavily in favour of its citizens, as well as having put insurance policies in place or having financial reserves in escrow to ensure that even if the business falters, the players will receive payment. Knowing this, you can safely bet on such a brand as a high-value, low-risk, long-term casino to sign up with.
The inverse is also true; brands who avoid any well-managed jurisdictions and use casino software that doesn’t care what their operators do should send up warning signals. They do for us and that is why we would never include them as potential Top 5 nominees.
List of the most strict regulators that provide the highest protection for players and casino operators:
We live in times where fast services and technological advancements are driving our day-to-day lives. It’s only natural to also expect a casino to offer fast payout options. At CasinoWow, we believe in always making the right selection of casinos for our visitors. That’s why when rating them, we filter those online casinos that answer to many of our expectations. One of them is, of course, the speed of withdrawals they offer!
When a casino offers lightning-fast withdrawal options, it means that the gambling site cares about the players’ experience online and aims to provide the best possible one.
Not to mention, if a casino can offer super fast withdrawals, it also means this online casino shows financial stability, and the operator is well-established in the industry! Usually, casinos that are fast in their payout procedures also offer many payment options and have a lot of available features that benefit the players.
List of online casinos with lightning-fast withdrawals:
To be considered a brand of excellence, we expect our casinos to move beyond mere customer support and into true Customer Care! We spend hours testing the response times, versatility, overall product knowledge and first-time resolution capabilities of the brands we recommend.
We also take into account how many contact channels they offer – telephone, live chat, email, perhaps even through their social media channels like Facebook? Lastly, we also look at whether or not they can be trusted. When a support staff member offers to return your call with the information you need, or email over the documentation that is required do they do so when they said they would. That simple point of keeping their word is the cornerstone of a great support team.
List of online casinos with the best customer care according to our research and experience:
While entertainment and fun are great for marketing campaigns, the reality is that the online casino industry revolves around money. For that reason, we go to great pains to ensure that the brands we promote as industry leaders have industry-leading banking solutions in place.
We delve into the service providers they’re doing business with, have the big banking companies approved them? Have well-regarded web wallets like Neteller and Skrill (Moneybookers) successfully approved their applications? Have they gone the extra mile to help customers from all over the globe by providing more localised deposit and withdrawal methods?
Then there is also the process, do they make it as simple to receive your payout as they made it for you to deposit? Are there payouts speedy and efficient, or do they tie you up in red tape? Nothing that the very best will do for you, and that is why this is one of the key make-or-break factors in determining the eligibility of a gambling site for inclusion in our top list.
List of best online casino banking methods:
To be a leader in our list of top five online casinos, the brand needs to be passionate about the people they’re serving. Nothing shows more care and consideration for you than speaking to you in your native language. For many people, online gambling is a new or somewhat disconnected experience, and to make it that much easier for them by explaining systems and processes in their mother tongue will ensure we give that brand the kudos they deserve.
Then there is the ability to both deposit and withdraw in your local currency using a local banking method. This ensures that there is no confusion when it comes to conversion rates and how much of your budget is being used, as well as ensuring there are no hidden fees or unexpected levies.
Any casino that makes your life easier and more enjoyable gets the nod from us! See all supported countries at CasinoWow where you can enjoy safe and secure online gambling.
List of top countries targeted by the best online casinos:
When we look at the bonuses and promotions on offer, we do not simply look at the face value offer. More important than the value on the sticker is how clear are the terms and conditions. Do they clearly and concisely explain things like wagering requirements, minimum deposits, maximum withdrawals and other things which can detract from the enjoyment of the experience if they’re sprung on an unsuspecting player when they try to cash out their winnings?
The same is true for promotions. Do they clearly list if there are geographical or even VIP tier restrictions? The holiday cruise you’re so excited about might require you to get to the departure port at your own cost – if you live on another continent, the cost might be prohibitive.
In some cases, the mega prize on display is only valid for players at the highest VIP tier, as a newer player you might only qualify for a smaller prize. We won’t stand for brands who obscure their terms and conditions, our top contenders will make your participation in their promotions an absolute dream!
List of most popular online casino bonuses:
While many brands use the terms "Loyalty" and "VIP" interchangeably that is not a true reflection of the industry and what goes on behind closed doors. A true VIP program requires a sizable investment in terms of gameplay and more importantly deposit values.
To stand out as a big deal in this industry an online casino of worth needs to have the financial backing and the nerves of steel required to take care of any high rollers who come to play.
However, at the same time, they cannot allow their service and care of everyone else to take a back seat either. For this reason, we require our top-tier nominees to have robust Player Loyalty Programs in place, which will reward you with bonuses, prizes and more for playing on a regular basis.
Balance is the key to success, and serving both the prince and the pauper with equal dignity and care is the true mark of an industry-leading casino.
List of online casinos with the best High Roller and VIP loyalty programs:
VIP Account Manager, Daily Reload & Cashback Bonuses, Invitation to Special Events
LV Points rewards program, LV Wheel, Daily Bonus Credit, Free spins, and Reload bonus or LV Points
VIP Account Manager, Personalised High Limit Games, Exclusive Promotions and Giveaways, Invitation to Special Events
At the end of the day, 99% of our time in an online casino is spent playing the casino games on offer. Whether it’s because it makes you smile, you love the bonus features, or it’s the one you had your first big win on and you know it’ll happen for you again, the quality of the casino games ultimately colour your opinion of the casino as a whole.
When we rate a casino's game offering we consider several key aspects of their library – do they offer a quality game with great graphics and smooth gameplay, do they have live dealer table games, do they offer slots tournaments, are there progressive jackpot games available and are their games optimised for mobile play?
A casino offering all of this (and more) has partnered with the best game providers in the industry. They have decided to provide you with a premium gambling service; they’re investing in their brand, which means they’re serious about building a sustainable and trustworthy business. These are the casinos we want to give recognition to, the ones looking to do it right!

The online gambling industry is one of the world's largest and most exciting sectors. Not only does it represent some of the most outstanding achievements in the early adoption of new technologies and the implementation of existing tech, but it demands a level of excellence and creativity not found in many other markets.
We place a premium on online casinos that treat players fairly, offer value for money, and work to promote a positive online gambling experience. The other side of the coin is the growing number of casino sites players should avoid due to predatory or unfair terms and practices.
To help our community share their positive experiences and shine a light on the casinos striving for excellence, CasinoWow hosts an annual players' choice award called the WOW Awards.
The WOW Awards are an annual player-driven award ceremony where you vote on the best and brightest online casinos, games, and providers of the past year.
The team at CasinoWow compile several lists of nominees based purely on their performance and player feedback over the year. It is impossible for a casino operator to buy or negotiate their way into the awards as the ratings of the sites are publicly available on the CasinoWow website.
Each year, you can help pick the latest WOW Award winners in the following categories:
Once the nominees for best online casino have been announced, the gambling community gets to vote for their preferred operator or participant in each category.
What makes the WOW Awards unique and exciting is the interplay between the players and the brands that have been nominated.
Once the nominees are announced, they are posted on a special webpage dedicated to collating the votes for each category. Users must log in with their registered email address to place their votes. This process ensures fair play and accurate results.
The nominated parties are notified of their nominations and then have approximately a month to campaign for your vote. We allow these casinos and streamers to share their nomination, as well as which category they're in the running for, with their customers and online communities via email and all social media channels.
After the fun and excitement of the month-long build-up, we allow 48 hours for voters to make their voices heard at the polls. We take the next 72 hours to ensure that there are no bots or duplicate votes and announce the winners via email, social media, and an update to the Winners section of the WOW Awards landing page.
We do not take the safety and security of the information you share with us lightly. We use the same levels of encryption on the WOW Awards pages as on the rest of CasinoWow to protect your right to privacy.
This focus on security means you can trust that your personal information and voting preferences for the best online casinos will remain private and not be shared with any third parties in accordance with the General Data Protection Regulation (EU GDPR).

This is why we have created our very special Top 5 Online Casinos list, and we hope that it will help you become a better player!
