Choosing The Best Online Casino

It’s important to know the criteria and be able to grade operators. Once you know few tips and find a trusted expert opinion, selecting one gambling site out of hundreds becomes easy and stress free. But if you prefer making up your own mind about everything and have no experience gambling, this is going to be a challenge as a lot of things need to be analyzed.

Best Online Casinos


This is a key characteristic that tells how much trust you should give without knowing a thing about the operator itself. The stricter and more reputable jurisdiction is, the safer the environment. Top tier gambling authorities implement and enforce variety of regulations to prevent fraudulent activity and protect gamblers. Maintaining integrity and safety at the highest level costs money that’s why these licenses are usually expensive.

Reputable license is a positive characteristic, but is not a guarantee of the premium quality. What that means for players is the chances of being treated unfairly are significantly smaller. Below we discuss three most widespread licenses.

  • One of the best licenses casino can have is issued by the UK Gambling Commission. UK regulator is actively monitoring its licensees and has set out regulations to make gambling safe, secure and responsible. This is a local license that is applicable to the UK only, but operators accept international customers with few exceptions.
  • Opposite to the UK, Curacao has chosen a very liberate approach to licensing and overseeing the industry. As a result, picking a Curacao casino without prior research is a real gamble. As control is weak, some operators run shady businesses and they work along with legitimate and honest operators that have exactly the same license.
  • Malta has become a perfect option for many casinos as it isn’t that expensive and demanding as UK, but sets out high standards and enforces its regulations. It’s an internationally recognized license allowing companies access to multiple markets at the same time.

Possible downside of such demanding and expensive license is that casinos will have to cut some costs to stay afloat, and one of the ways to do that is to opt for lower RTP versions when possible.

Game Variety

This is the criterion that’s hard to overestimate. Games are the reason players join casinos, and they should be fun and fair. Everyone would have their own game preferences, that’s why casino sites usually offer hundreds of choices and the best online casino would offer few thousand games.

The focal point of any games collection is slots, live dealer and table/card games come second. The quality of games varies as they are produced by many developers some greater than others. At the moment NetEnt, Yggdrasil, BTG, Quickspin and Relax are among top casino software suppliers, and they all focus on designing slots.

Evolution is the major trail blazer in the live casino vertical. For a long time it practically had no decent competition but lately other providers joined the market further boosting innovation. This category is considered to be a must and top tier online casinos offer the best live dealer titles.

It’s not only quantity of the titles that matters, but versatility. Games selection must be diversified and exciting to satisfy the requirements of gamblers with different preferences. There should be classic as well as innovative titles, progressive jackpots, unique mechanics, low/medium/high volatility games, launched by major providers as well as smaller studios.

Bonuses & Promotions

Rewards for making deposits and other activity have become integral part of online gambling and even though this aspect isn’t as important as casino legitimacy and games choice, it can be a deciding factor for players. Good bonuses are those that help extend the time you buy without forcing you to take extreme actions, for instance, wager way more than you usually do.

Typically, good casinos offer a welcome bonus pack, which is a series of one time offers to attract new customers. They are then followed by weekly promos that retain existing customers. Occasionally players receive promo emails with special free spins or other promos.

Welcome Bonuses See all

Best promotions internet casino can offer aren’t about getting more free spins or credits. Wagering requirements are the key element of all promos as operators don’t distribute bonuses without any commitments from gamblers. Standard requirement is to play through the bonus amount 30-40 times. This should be done without breaking other rules such as max bet limit, restricted games, etc.

Cash back and loyalty program are also important. Players got used to getting back a share of their weekly losses, which is usually 10-15% of net losses. Operators encourage player loyalty by running a loyalty program which is about point collection and level upgrade gifts. Loyalty points are then exchange to real cash or other staff.

Fast Payouts

This is another key element of a great casino. It’s never fun to wait for days to get your cash and there’s no reason this process should take long. Unless a gambling site is poorly managed or it deliberately delays withdrawals, payouts get processed fast. Today best online casino spends few minutes to send money but few hours are still a benchmark.

Verified accounts get their requests processed within few hours, while unverified players might be asked to send documents first delaying withdrawals. Once transaction is approved, players won’t always receive money the same instant. Depending on the banking method, there can be some time required for money to arrive.

Withdrawals can be lightning fast when casino invests in the technology that allows automatic cash out request approvals. In this case any suspicious activity is flagged by the software and then checked manually, while legitimate players that have done nothing wrong enjoy instant cash outs.

Customer Support

Professional support is sometimes overlooked when making a decision. But this is as important as casino reputation. It isn’t always obvious from the very start whether support is helpful or not. But there are some telltales of unprofessional customer support. Being rude is one of them, unable to respond to simple questions is another one. If casino staff is hesitant and unsure in simple situations, they’ll probably be useless in resolving some serious issues.

Best online casino support is polite, helpful, fast to respond, knowledgeable and ready to walk an extra mile to assist players. There should be multiple channels available 24/7 to reach customer support. Live chat is usually the most common option along with email. Some operators additionally give their phone numbers.

Reviews and Ratings

What other players say about casino you consider is vital. But the problem is there can be opposite opinions as everyone views exactly the same product differently. Keep that in mind and at the same time try to tell fake reviews from real ones. There are reasons people leave negative or positive fake reviews, you just need to be aware of that practice.

It would be wrong to assume best operators won’t have negative player reviews. They all have some criticism coming from gamblers, but the share of unhappy customers relative to happy ones is small. Best way to know online casinos indeed offer good or bad services is to pay attention to the facts. Players giving details on why they think of the operator the way they feel would have greater value.

Complaints are a quality source of information just because we can listen to the both sides of the conflict. Looking at the casino response, we know if the player complaint is legit or not. It’s also useful to see how operators deal with the complaints.

Ratings are just like player reviews, they have value only when they are honest and accurate. Online casinos that top the ratings won’t necessarily offer best services. So, you should find a resource that you can trust or do your own research.

Mobile Gaming

By default every casino today is mobile friendly, so there’s no way top tier operators will have problems with that. Websites automatically adapt to different screen sizes making special mobile apps redundant. Games are also mobile optimized and that’s content suppliers’ job to ensure that. Thanks to HTML5 format, casino content available on the go regardless of the device.

Types of the Best Online Casinos

The internet casino industry came pretty much to a single optimal solution, which is a site with the full set of features available to mobile and PC users. There used to be different products for each platform before technology developments allowed the creation of a universal solution.

No Download

Accessing all the features and games through a casino website is the most convenient option. No download required for PC and mobile users. Beautifully designed and easy to navigate website is a real asset. Most operators only have websites as everything else is redundant.


The time of downloadable casino soft has long gone. Today only few gambling companies would develop apps for mobile users and hardly anyone is doing that for PCs. Best casinos available online have a single website that performs all the necessary functions.


Mobile optimization is one of the keys to a successful gambling site as more and more users switch to smartphones. But ensuring smooth mobile experience doesn’t require a lot of extra investments as there are no apps to develop, no special mobile websites to design. One site version with responsive design is all they need. All top operators make sure players enjoying games on the go have a hassle-free, enjoyable experience.

Live Dealer

The amazing dynamics of live dealer vertical has made it one of the key products online casinos have to offer. Live casino games require no special tools and aren’t bound to PCs. So, you can play it anywhere, anytime and on any devices available.

Leading live dealer content suppliers has made this product super exciting and fun and won over crowds of gamblers. Initially games were live streamed exclusively from specially designed studios. But today players get to gamble alongside casino enthusiasts located inside actual gambling venues. Variety of games has also extended significantly, old classic titles with a modern twist, innovative game shows and new products such as live dealer slots.

The Best Online Casino Games

It’s important for the operator’s success to partner with as many legitimate providers as possible and have an extensive and versatile games collection. This is to ensure players, regardless of their preferences, will find what they need. There are key casino game categories best operators offer.

There has always been demand for classic blackjack. With the element of a skill game and very thin house edge savvy gamblers are sure to love it. Blackjack hasn’t changed much, but there are few interesting variants that are available, including Switch, Surrender, Single Deck. Yggdrasil specializes on slots, but has a series of beautifully designed blackjack titles with their unique 3D animated dealers Sonya, Lucky and DrFortuno.

RNG format isn’t the only one. Blackjack is one of the favorite titles in the live dealer vertical. Providers have multiple tables with a range of limits and lots of variants. Evolution, being the powerhouse of innovations, has launched some unique blackjack variants such as Infinite, Power, Blackjack Party.


Classic poker types such as Texas Hold’em, Omaha and Stud aren’t usually offered by casinos. But some poker games are still an option and video poker would be the most popular choice. Best selection of online casino video poker consists of dozens of variants. There isn’t much development in this area and typically games feature quite primitive design, but that shouldn’t put off gamblers.


This is a must have game, but not as popular as the rest of the categories. Still, many players enjoy it. Basically, there are no any bingo hits familiar to the wide audience. So, here and there casinos would offer different bingo and lottery games depending on what providers they partner with.

That’s where the best all time casino hits concentrate. This is a ridiculously popular category and majority of the developers work in this vertical. So the amount of releases and the tendency to innovate are crazy. Every month companies launch dozens of new titles with at least few of them drawing a lot of attention.

Despite heavy competition and enormous production rates, best slot titles appear at online casinos not that often and only select games pass the test of time. There are few classics that have been around for years and still top popularity ratings: Starburst, Immortal Romance, Dead or Alive, Book of Dead, Jammin’ Jars, Money Train.

Those who chase massive wins pay close attention to some slot titles with extreme volatility, huge max win potentials and progressive jackpots. There are plenty of jackpot games with varying payouts that can exceed 10 million Euros. Microgaming is the leading company in this area as it has launched numerous progressive jackpots and two of them have the greatest seed value of all times.

  • Mega Moolah is familiar to many experienced gamblers as a record breaker and the one that regularly drops multimillion prizes. With seed value of €1 million, its record stands at €18.2 million. Hitting Mega Moolah Mega jackpots for now is the best thing that can happen to any online casino gambler.
