All right, before we even start preaching about the games, payments, bonuses and all that other stuff you might be interested in. Let’s take a moment to discuss our review methods.
At FreeSlots99 we have a whole team of dedicated online casino experts working in your favor as we evaluate top online casinos by specific aspects. Remember us mentioning how different preferences can affect your choice? Well, we tend to help players override those in general by giving them the top picks according to review categories that aren’t even up for debate.
There are some boxes that every single decent casino should check, and here’s our two cents on the review process.
Well, now you know a bit more about our review process, but how do we get to our list of top 10 online casinos, you might ask? It’s a bit more complicated than that since we want to provide our readers with a personalized experience which means we’ll do our best to give you the best picks in your area and according to your preferences.
Take a peek at these pieces of advice, and we’re confident you’ll find a tailor-made casino suitable for your preferences in no time.
Finding the best real money online platforms also largely depends on the games you’ll find on those websites. After all, only top rated online casinos come with superb gaming collections that include online slots, table games, live games and some more recent game types like Crash or instant win games.
While we are at casino games, it’s impossible not to point out the importance of online slots. Our team members here at FreeSlots99 spend days researching the best games so you can play free versions of more than 28,000 slots right here in one place. You can put the gameplay mechanics to the test and decide which games you prefer over others.
Now, back to the point – for a site to be given the title of the best online casino, it needs to include various game types. We’ll tell you exactly what to look for below so you can have an easier time finding the perfect place to place your bets.
Another key quality of the best rated online casinos is having a wide range of bonuses. These include some obvious options like welcome deposit match offers that are more or less offered by every operator. However there are some bonuses that add extra value to the site so you should be looking for all of these:
When recommending the top-rated and trusted online casino platforms, our team always takes extra steps to ensure that we bring you sites offering all of these. Or at least most of them. Using a free spins offer gives you the chance to put some slots on the site for a test and get a chance to explore the bonuses and features without spending your money. If you ask us, no deposit bonuses are just as beneficial since they give you a chance to win a prize without being required to put down a payment first.
If you’re still learning your way around the iGaming industry, we need to talk about online casino software providers. Luckily, our team members are experts in the field so we’ll give you a couple of pointers as to which providers to look for. We’ve got demo slots from hundreds of different software brands on our platform, and these are some of the biggest names:
Of course, new providers are also emerging by the day so it’s even tough to keep track of all the names popping up. But you should be looking for those that are approved and verified by major licensing bodies like the UK Gambling Commission, the MGA or software fairness testing agencies like eCOGRA.
Every site features a unique combination of games and providers but the good news is – there are hundreds of operators offering top-rated ones. It also helps if you decide to check the game ratings reviews before deciding which casino to join.
This can give you an overall impression of what you’ll be looking for, and it doesn’t hurt to hear other opinions from players before you make up your mind. At FreeSlots99 we’ll do our best to keep you posted on the best providers and games to go with when looking for top online casinos and gaming platforms.
Well, now you know it all – we’ve gone through the key stuff to focus on when looking for a decent online casino. Now the only thing left is to discuss some technical things like payment methods.
We know you probably don’t have these in mind as a top priority but trust us – choosing a trusted online casino without going over the payment methods first is the worst thing you can do.
Not only do shady casinos use insecure payment options but you might even end up exposing your banking information when joining such platforms. We all know what kinds of troubles that could lead to so picking a decent site with reputable payment options is a must.
Here are some of the most common payment options to focus on when it comes to security, instant transactions and low casino payment fees.
Overall, e-wallets are among the most popular options these days, allowing you to make real money casino payments within minutes. Withdrawals are also fairly quick so that’s also a good thing. On the other hand, you can also use bank transfers as trusted payment options, but then again, they could take quite a while to process. In our experience, even up to a few days.
Now comes the fun part – modern-day casinos all allow mobile gaming through the latest HTML5 technology used, as well as other optimization aspects. That’s why you can download the official mobile apps of the best rated online casinos from our list to play all of your favorite releases on your Android or iOS device.
However some top online casinos offer a different approach without the need to download any software. Those sites offer official mobile pages and mobile versions which can be accessed directly through your browser.
So playing those means you’ll only have to use your device to visit the official page of the site and the mobile version of the page will load instantly.
There are loads of reasons why our experts look for mobile-optimized sites. First and foremost, it’s easier that way, since you get to play on the move and place your bets without having to leave your favorite chair. However it’s also more convenient in terms of optimization.
Most casinos are nowadays designed for mobile use so you might experience some lagging on PC devices that otherwise wouldn’t be present on mobile devices. So how to know which online casino sites should enter your shortlist in this category?
Simply look for mobile-friendly platforms that either have official Android and iOS apps or go with sites optimized for mobile play via browsers.
Before we wrap up with this guide, we need to address the responsible gambling side of things. All modern casinos real money sites need to include responsible gambling features and tools to help players like you stay within their boundaries. Of course, the casino is not responsible if you go overboard but it always helps if you have a few tools you can use to limit yourself.
We’ve all been there – sometimes you simply get too much into the game and that leads to some bets that you shouldn’t have made. To cope with that, you can use responsible gambling features such as deposit limits, playing limits, self-exclusion and others.
In our online casino reviews, we like to point out those features as useful options for players to stay aligned with their limits. That means only gambling with what you can afford, and that way you’ll never have a problem gambling online. Or you can use helpful hotlines listed on our recommended sites among the best online casinos for real money to get help.
These mostly include responsible gambling agencies and programs like BeGambleAware, Responsible Gambling Council, and others. If you’re in it purely for the thrill of the game purely, you can always visit FreeSlots99 and play demo versions of your favorite slots. That way you’ll still get to have lots of fun and never risk losing a penny on slot machines.
We’ve now gone through the main details you’ll need to know when choosing a trustworthy casino so hopefully you’ll be able to use the main takeaways to do exactly that. Of course, we know that finding the best online casino sites can sometimes be more challenging than it seems. If you keep in mind the gaming quality, licenses and payment methods, we have no doubts you’ll easily find a worthy casino.
Plus, you’ll now be more than equipped to choose sites with complete mobile optimization and bonus offers to make your experience much more fun! Remember, if you still need any inspiration, you can always rely on our free slots library here at FreeSlots99 for some inspiration!
