Find the Best Online Casino to Play At

Everyone knows of casino comparison sites, but the Casino Professor is unique. Because players are different, the Prof wants to help find YOUR best online casinos by comparing their features with your preferences. This includes the entire process –  from the casino bonus you initially receive all the way down to your preferred payment methods, slot providers and more.

Getting these just right is very important, because why would you settle for anything less than the best online casino? By using the Casino Professor’s filter tools, you’ll be playing slot machines for real money in a matter of seconds.

Oh, and although not all online casinos are safe and legit to play at, the ones with strict licenses (such as from the UKGC or MGA) generally are. You can find only those at Casino Professor.

Filter casino sites

That’s because, with filters, you can easily choose between a variety of features to create your very own online casino list. Let’s take you through each filter so you know what to look for.


If you use this filter, it will select the top casino sites from a particular category, with example options being:

The Categories option is probably the quickest and most efficient filter of them all.

While you won’t be able to narrow down your list of casino websites too much, you can choose a popular feature or characteristic that many other gamers are searching for to start playing.


As this page contains all of the Professor’s online casinos, he thought he’d make it easy for you to filter the options based on one of the most important parts – the starter package.

What’s more, you can switch between three different first deposit offer criteria to find exactly what you want:

  • Percentages – Find deals that range from 0-100%, 101-200% and 200%+.
  • Extra Money – What extra funds do you want in your account? Up to €1-100, €101-200 or €200+.
  • Free Spins – Select if you fancy a few rounds on the house, alongside your first payment.

NOTE: The Bonus filter is for first deposits only. See the Casino Professor’s no deposit free spins for offers that you get immediately after creating a new account.

Casino sites search and filters


For an advanced selection of criteria, you can select the More filter. From this view, you adapt your list of online casinos based on the following terms:

  • Software – Up to 40 different slot providers, including NetEnt casinos, Play’n GO sites, Novomatic domains and Microgaming Casinos.
  • Payment methods – Select how you’d like to make a deposit
  • Gambling Licenses – As mentioned above, all trusted real money online casinos need to have at least one!

Finally, if you have a casino in mind but you want to double check what the Professor thinks about it, simply search using the bar provided.

However, this is an advanced search that goes beyond just online casinos. That’s because the keywords you enter will be used to search through all the casinos found on the entire Casino Professor site, opening up a world of options.

For example, you could search for terms such as “VIP” or “Live Chat” for a list of casinos that have these terms included within their page.

Why These Are the Best Online Casinos

Once you’ve come across a few matches, you can either head straight there to try them out or delve further into the details by opening the Professor’s own reviews. But how do you know that this list of casinos is the best?

Well, it’s within one of these reviews where you’ll find a comprehensive summary of all the casino’s ins and outs – plus the Prof’s honest and trustworthy rating.

If a casino has reduced him to tears then you’ll know to steer very clear – although that almost never happens. However, if one brings out his heart eyes – which isn’t too common – then you’re onto a winner.

But what experiments is the Professor conducting to reach a final conclusion? We’re glad you asked!

The Prof’s Unique Ranking Formula

Online Casinos under Professors review

Unlike other comparison sites, the Professor applies a strict checklist against every prospective online casino to separate the pretenders from the contenders.

Here’s how each and every one of his analyses takes its course.

An Initial Screening

You’ve probably noticed that the Professor isn’t exactly a millennial, so he’s not in the mood to waste time. Before he even looks into a casino website’s qualities, he makes sure they’re fit for purpose.

What’s he looking for?

Well, as mentioned above, all credible casino websites need to have a valid gambling license – so that’s the first thing to tackle. Ideally, the issuer would be the UK Gambling Commission or Malta Gaming Authority, but there are a few other, lesser-known but genuine, licensers too. If there’s even a whiff of doubt with licensing, the Prof won’t be interested.

Likewise, the approved online casino must have strict security and safety procedures in place to protect you from all kinds of threats. This ranges from internet security – such as HTTPS encryption – to responsible gambling and everything in between.

Next, he considers whether the platform is fit for you. Basic aspects such as the website being in English or whether the essential payment methods have been provided are looked at.

It’s also at this point when prior reputation is taken into account, with the Professor previously finding horror shows with pirated games, for example. Of course, these go straight in the bin.

Then it’s the Good…

If a casino site clears this initial checkpoint, the analysis then moves on to what elevates them above the rest. Anything that could be subjective – such as what constitutes a good welcome package – is obviously taken into account. But any glaring omissions are caught up in this particular net.

A good casino site makes the Professor happy

What’s he looking for?

First and foremost, slick and sleek mobile casino is an absolute must. Dedicated apps are a useful add-on which would score plus points, but the bulk of the matter lies within a good, responsive design. Without one, it’s not going to be particularly attractive to gamers…

Is there a Promotions page? How about a reward scheme? Are slot tournaments included? These are the kind of questions that are asked to guarantee you’re provided for after registration. A minimum of one of the above is expected, but the high flyers mix and match several. Also, the best casinos have a stocked library of online slot machines.

Finally, if a few handy extras are thrown in then that often wins the Professor over. Manual flushing – which is the process of locking in requested withdrawals – falls into this category, as does something like an advanced game filter system.

These features show that a site has put a lot of time and thought into user experience, proving they’re dedicated.

…And the Bad

You can’t claim to publish critical opinions of online casinos without pointing out the negatives, so the Professor is careful to include these as well.

Of course, these shouldn’t ever be dealbreakers – or else a casino would never get past the initial screening. Instead, you can think of these as little pet peeves that aren’t (yet) rectified.

What’s he looking for?

While we begrudgingly accept wagering requirements at casino sites, if promotions come with too high wagering then this isn’t great. You want to be given at least a chance to win real money at at online casino, so anything from x60 or above is problematic.

One common gripe that the Professor continues to have – including at some of the most acclaimed domains – is no 24/7 support. A reliable and effective response is expected at all times – so those who aren’t always on call will lose out slightly.

Finally, a lack of innovation would irk the Professor somewhat. Even the top casino sites at the moment realise they’re not perfect, so there should always be an element of surprise lurking around the corner.
