Slot sites are everyone’s favourite form of gaming entertainment; I can tell you this much. For my part, I have spent the better time of my recreational gaming time studying new slots, playing the old classics and generally sticking with the top slot sites available on the market today.

But to discover what the best slot sites are, you will need to have a few helpful pointers. In my experience as a reviewer, I have accumulated the knowledge necessary to help you separate the good ones from the bad apples.

And here I stand today, bringing you the best slot sites that will help you enjoy hundreds of amazing games and all their unique features. Let’s talk about those worthy sites.

Variety of Slot Games – Always a Good Sign

One of the most important aspects to me as a player – and reviewer second – is to have a rich choice of games, to begin with. I can’t quite settle for 100 games you see, because there are over 15,000 online slots out there, and the more you have access to, the better.

You might be thinking – “wow, 15,000 is a lot,” but variety is always the way to go with these things. A great slot site won’t focus on adding every single last title, but you will see a good mix of classics and innovative, fresh releases.

Some casinos will offer around 500 titles whereas others will bravely push and have as many as 2,000 and 3,000. Whatever the base number, however, I can guarantee you that the top slot sites will all focus on continually adding new releases, so you always have access to the games that are currently capturing players’ attention.

And that is just what makes a great casino slot site that – the continuous strive for self-improvement. I put a great emphasis on having a website that is developing itself at top speeds. Adding slot titles from the latest releases is a sign of that.

Don’t Skimp on the Developers

Having plenty of slots is great, but what matters just as much as having a mixed bag of developers. Why is that so important? Well, each big brand there, whether that is NetEnt or Betsoft Gaming, has developed its own unique signature in the industry.

This allows you to explore completely new features, exclusive to a particular studio. You could argue that most of these features overlap, but there are also those that are trademarks, and you can only access and enjoy them if you choose a game by a particular casino.

Today, there are at least 30 flagship brands that develop and supply games and possibly hundreds of studios that work under the same brand as those big studios and help them push forward their products.

Now, you needn’t know all of them, but you can rest assured that no matter who the developer is, as long as they carry one of the big brand names, you can expect a quality product.

Pack Your Games with Features

One of the main challenges for the best slot titles is to offer a portfolio that is not only diverse but also offers sufficient bonus features. There are loads of possible things that a developer can do to optimise their slot, and a great site will want those games to be part of its portfolio.

But what features exactly? Well, you can pretty much think of anything, and the site should manage to meet your demands to some extent. All slots should offer a mixed bag of scatter and wild symbols, special bonus symbols, and fantastic features such as free spins, multipliers, progressive and fixed jackpots, second bonus levels, and more.

There is really no specific threshold on how many features you can put into a title you like, and that’s the best way to describe. You have certainly heard me talk about cool features such as Avalanche Reels, Walking Wilds, Cluster Pays, and many more.

Innovate the Interface and Experience

Now, a thing that all slot titles will try to do is create a level of engagement that is unprecedented. That’s achievable not only by selecting a specific number of games or developers but also creating game missions.

I have reviewed quite a few casinos that offer the feature and allow you to join a sort of a quest that serves as your “standing” in the casino. The more points you accumulate, the higher your rank becomes and the more missions you have completed.

Right now, I can think of Playamo Casino, which allows players to focus on some top-notch slot titles while still completing casino-wide quests and missions. It has such innovative features that really help the best slot sites stand out and create an experience that is relatable, easy to understand and ultimately – so much fun.

Not least, all innovative slot experience should also be fully compatible with mobile, making for a fun and accessible platform overall. I have touched on both the instant play and mobile app experience in separate sections as well.

Free Spins at Slot Sites 

Free spins are a sort of an incentive that not many players can say “no” to. I will admit that I have never hesitated to claim a free spin offer. In fact, I have reviewed at quite some length what free spins are and specifically how these bonuses help you make the most out of your gaming experience.

Free Spins as Part of Games 

Since we are talking slots here, I would like to remind you that free spins are not necessarily just a form of a bonus. They are, in fact, part of the games you will find. Many Microgaming, NetEnt, Play’n Go and Yggdrasil – among others – include generous free spins levels.

You can often get 10, 15, 20 or even more rerolls for free! And to be honest with you, this is precisely the type of slot experience I always look for myself, when all the reviews of the day are done.

No Deposit Free Spins at Best Slot Sites

Speaking of the best slot titles, though, I can hardly fail to mention the available no deposit free spins. These bonuses are designed to bring the gaming experience to the next level for you, and the best part is – they don’t ask for anything back.

No deposit free spins often come in great numbers, anything between 10 and 100 free spins, really, and you can use them on either a specific studio’s games, all slots or pre-selected titles. Whatever the conditions, though, I can assure you they are quite worth it.

Another thing to keep your eyes open for is the no-wagering or zero wagering free spins. These aren’t just no deposit spins – they also don’t ask you to meet the wagering requirement. You stake and keep your winnings right away.

Of course, there might be a small cap on how much you can win in total, but this is not bad at all. It’s understandable that a casino wouldn’t be willing to throw away too much money without anything in return.

Even then, I feel very happy with the current practice of allocating no deposit or/and zero wagering free spins.

Best Slot Games to Win

Now, as a passionate slots fan, you are probably wondering the best games out there are, and specifically – which games give you the best chances to win. Because the industry has long such a long way, there are hundreds, if not thousands, of titles that provide you with generous payouts.

If you want to distil thousands of slot games down to the best-paying ones, I can help you out with this, but you may not find all of these slot machines on the same website. Nevertheless, it’s always a good idea to know what to expect.

Blood Suckers 

I really enjoy Blood Suckers by NetEnt for a number of reasons. For starters, the game offers a 98% payout rate, which is hard to beat by any other competitor on the market. The graphics are fantastic, the title runs smoothly on mobile, and you have 25 paylines to choose from when all is said and done.

In true NetEnt spirit, you can always tinker around with the betting limits so that you are in full control of your game funds and even play in a demo mode to find out more about the game.

One of the biggest advantages of this slot is that the low-paying symbols are already paying well above the industry average and as to the Bonus Game, Wild and Scatter Symbols, you can easily get a 7500x payout.

Oh, and remember when I told you that you could claim up to 10 free spins as part of a slot game? Blood Suckers is one such game, and if you land five scatter symbols, you are looking at ten free spins. Granted, many titles offer as much, including the Egyptian saga in Book of Dead and another NetEnt’s special game – Starburst.

Goblin’s Cave

Now, I am really going to take you way back when a three-reel slot was the norm. Goblin’s Cave is, as they say, an oldie but goldie. The game comes with the whopping 99.32% in potential payout making for what is very possibly the best-paying title in the recorded history of online slot gaming.

The visuals are, in fact, very pleasant and Playtech has done an excellent job of providing you with a title that truly makes the cut. Apart from the high RTP and straightforward gameplay, there are enough features to keep you entertained and make your experience truly memorable and worthwhile.

You can participate in the dedicated pick-and-win bonus games which will put you as a player in the centre of the experience, able to make your own luck. The game truly comes with an element of skill because the better pick you make, the better reward you stand to benefit from.

I still understand that it’s mostly a matter of luck, but it does feel great nevertheless. You can even choose to stick to a symbol if you like it and hope for it to line up with other paying symbols. Not least of all, the betting range is very generous, making it just so simple to play on a budget or even for free.

Last but not least, the gameplay remains quite innovative, and truth be told, many games even today fail to meet the high bar set by Goblin’s Cave and its bonus game.

Jack and the Beanstalk

With an estimated 96.3% RTP, Jack and the Beanstalk is definitely the best paying game out there. So, the question is – why do I even consider it today. Well, I have played thousands of slot games in my time, and I am fairly certain that the best slot sites will always feature this title.

Playing this NetEnt game is one of the best gambles you can make, thanks to the so-called Walking Wild symbol. Apart from having an awesome bonus game and a brilliantly themed backstory, Jack and the Beanstalk also comes with the so-called Walking Wild.

The wild continually retrigger free spins. There is no cap on how many free spins there are as long as you keep getting Wilds. And the free spins are retriggered until the Wild has slid out of the grid. The Wild slides one box per spin, and while the first Wild is making its way out of the grid, you may as well get a second one lined up!

That makes it possible to enjoy a potentially huge payout off a single spin! Once again, I know this is just luck, but in the time, I have spent testing this particular slot, I am nothing but convinced that it definitely stands as one of the best options out there.

How to Win More Playing the Slots?

All best slot sites have to give you a fair chance of success, wouldn’t you agree? So, how exactly can you take advantage of a great casino website and make sure you are adding to your winning potential. It’s actually all very simple – you just need to stick with a few general and straightforward rules:

  1. Stay in control of your bankroll – Slots are so fun, and you can get carried away quite easily. Yet, as someone who has had the pleasure to play for years now, I have a few tricks on staying on top of things and controlling my bankroll is just one of those things.
  2. Pick the best slot sites’ bonuses – If a site offers you a bonus for the slots, consider picking it up so long as the rollover requirements are worth your while.
  3. Play the games you enjoy best – Another important aspect of success is to play slot games you enjoy. That way, even if you end up losing a bit, you will still have had a blast playing.
  4. Try to play the highest RTP titles – In general, you will want to aim for the 96%-97% return-to-player rate percentage. You don’t have to just go after Blood Suckers and Goblin’s Cave though. There are hundreds of slot games that pay generously at the top slot sites today.

Megaways or Progressive Jackpots – Which Is Better?

When it comes to the top slot sites, you can rest assured that they have it all. Over the past few months, I have paid particular attention to online slot reviews – to name the megaways and jackpot slots.

I find both types of games to be quite exciting. Progressive jackpots will admittedly focus on that one-in-a-lifetime big jackpot that will completely alter your life. Even then, I feel that jackpots games are more for the amusement aspect than they are for turning your life around.

Of course, I admit that I often play with the idea of landing a massive win and hopefully having a bit of an extra million or two. Yet, this doesn’t happen often enough.

On the flip side, top slot titles will also feature the so-called Megaways games, which often exceed 100,000 in terms of total paylines. The payouts here are not necessarily the same as in jackpot title, but I can promise you they are very much worth it.

Now, you always have to keep in mind that each game – megaways or otherwise – has its own unique rules, offering you a chance to win as per different game scenarios. For my part, I have noticed that the best casino sites out there will always provide you with all types of slot machines to test, try and ultimately have fun playing at!

Is My Slot Site Good Enough? 

Picking a top slot site can often come with its own challenges. That is why I have gone to some extra length to jog your memory and remind you how to pick a website for yourself. Now, we have already talked about some of the innovative features that you would want to see a casino offer, but let’s focus on those absolute musts any site should have.

  1. Properly licensed – The upsides of playing in a whitelisted casino jurisdiction are many. You will enjoy a level of player protection that no unlicensed casino can offer. Yet, you should always check the license of a slot site and see if it is actually permitted to offer casino products in your country
  2. Banking methods – The best slot sites also have the best banking methods. They are familiar and convenient payment options that allow you to deposit and withdraw without any delays quickly. I have covered all relevant banking options that the top slot websites must offer
  3. Customer support – Another thing to make sure that is on the desired level is customer support. You want to have a 24/7 contact with the casino or in the very least be able to address an issue regardless of the time and date – email, live chat, and phone support, plus a FAQ section are some of the things to look out for.

Anyone interested can find out how I rank online casinos in my dedicated article. What I can tell you for a fact, though, is that the best slot casinos will always make sure to check all the right boxes and provide you with a quality gaming experience.

So Many Best Online Slots Sites to Pick From

Overall, you will continue to see an amazing variety of slot sites that offer you just about anything of the features we have just discussed. The truth is that there are many brands that are now seeking to please players and meet their expectations.

And this, in turn, drives competition which benefits the player. The top slot sites will continually try to one-up each other and bring you the best slot product imaginable. Amid this competition, I always manage to find the best choices.

To be honest, there are many that seem to be quite decent – it’s just that with a bit of knowledge and willingness to navigate the world of iGaming and slot titles, you can always squeeze a bit of an extra opportunity.

However, don’t worry too much about it. One of the things I have seen many players do is continually question their choices. This, in turn, brought them anxiety. However, iGaming should be all about fun. And remember – when in doubt, just pick one of my recommended websites!
