About SlotsAdviser’s Casino Reviews & Ratings

Here are the factors we take into account when reviewing online casino sites:


The background is all about the company behind, the launch date and a casino’s general approach. We also mention important things like license, awards (if any), and other general aspects concerning an online casino.

Software and the Collection of Games

It is known that online gambling sites are being powered by online casino software providers. Some of them may work with as many as +60, others may just use one or two. Software providers come with different features, different games and different conditions in terms of a license. Some providers are great for slots, others might be good for live casino games, while others are just good all-rounders. Whatever you prefer, it is best to be informed.

Online Slots Offer

As is a slots-focused website, our main accent is on slots for obvious reasons. This is why we dedicated a special section for describing the slots offer. Although casino sites look more or less the same, they are not the same. A slots-lover will be rather interested to play at a dedicated slots casino site and what we do is to point out this aspect.

Casino Bonus & Promotional Offers

Claiming a casino bonus is something that can help you get started. regardless if it’s a deposit bonus or no deposit free spins offer, it is always nice to get something for free. This is why we list all the best casino bonuses and mention them in our casino reviews. Please note that many of our bonuses are exclusively-negotiated, not available anywhere else. So make sure you take advantage of them while they last!

Banking Methods

This aspect is crucially important. You can’t really play real money slots unless a deposit is made. To make a deposit, a deposit method of your choice must be supported. We save your time and list all the banking methods online casinos accept, feel free to check our reviews and find an online casino that takes your preferred payment method.

Mobile Options

Playing on the go is not just cool today, it’s a must-have thing in today’s gambling world! This is why we always mention the mobile offerings casino sites come with.

Customer Support

Whatever problem you may have, you will just want to have it sorted out. And this is when customer support pops up. Knowing in advance what channels it comes by and how prompt and professional the customer support is, may well count when choosing an online casino. What we do is to test the online casino operators with random question/problems in order to note how fast and professional they respond.

Final Verdict

The Final Verdict is a general conclusion about the online casino the review is about. So if you don’t have a lot of time and just want a quick opinion, feel free to check our final verdicts!

Why read online casino reviews?

Some of you may be wondering why online casino reviews are so important and why people recommend you to read them. Why can’t you simply join a casino and form your own judgment on its aspects instead of paying attention to someone’s rating?

You can, of course. But, if you put your trust into objective online casino reviews you can experience various benefits and avoid unpleasant situations.

Here’s why you should read online gambling reviews

For preparation – casino reviews online include descriptions of the site layout, mobile compatibility, supported payment methods, available customer support, as well as relevant details about the software and game quality. Knowing all this information before you start placing bets can relieve you from the initial adapting-to-the-unknown experience.

Narrowing down your choices – there’s just too many casino websites out there; once you start reading reviews, you’ll find it much easier to choose favourable sites to play at. Reviews are based on the feedback from seasoned players and casino experts who know exactly which qualities of the venues to point out. Through casino reviews, you can find out much faster whether the site you’re interested in actually has what you’re looking for.

Choosing trustworthy gambling sites – the trustworthiness of a gambling site is one of the primary concerns of every gambler. You want to play at a licensed casino online, right? By reading and comparing quality reviews, you can easily find out if the casino is well-regulated or not.

Avoiding rogue sites – when you come across a casino review that deems a casino venue as untrustworthy, the decision is easy to make – you won’t be playing at that casino.

They’re free and helpful – reading reviews online is completely free. You don’t need to pay a dime to receive all that helpful information and guidance. You just need to spare a few minutes and do yourself a favour by reading them. As a consequence, you’ll save both money and time, as you’re referred to reliable casino venues only.

Are Online Casino Ratings accurate?

As with anything in life, experiences tend to vary from person to person. You may have loved your three-night stay at a hotel in Rome, where someone else on a travel comparison site had a horrid time. The same can be said for online casino ratings, as our experiences are subjective.

Many online casino reviews come from a wide range of sources. Generally speaking, these tend to be either real players, affiliate sites (and some are paid to give good reviews), or saboteurs from rival casinos who spread false information. All in all, casino reviews which you do read are hard to prove as accurate, given the circumstances unless you truly trust the place.

Look out for trends

The simplest way to make your mind up is to see if there are any criticisms which frequently pop up in many different reviews and sources. For example, if you have noticed that a number of players are angry that the casino is withholding funds, this should set off alarm bells. The same goes for casino reviews that appear to suggest that the site can do no wrong.

Compare online casino ratings on different sites

There is a wide range of sources where those who are discontented with a particular brand can sound off. The best part is that many of these critics on sites nowadays tend to have profiles you can read, with a readable history of online casino reviews and casino ratings. You may find that the person giving casino A one star gives casino B ten stars, and casino C one star, also. This may indicate that they have a vested interest in casino B.

The proven way to find out if a casino is right for you is to check they are legitimate, and deposit the minimum amount and play as a test run.
