Best Online Casino Slots 


Naming the best online slot providers looks like a natural thing compared to naming the top online slots. The total number surpassed 10,000 titles in 2016, which makes picking out the top slots even more difficult as the variety is enormous. You have different layouts, feature-rich or bare, low, medium or high volatility, awesome graphics, or stuck in the 20th century and many more factors. However, looking at long-term statistics, we can safely name the following as some of the most played slots in online casinos right now:


  • Book of Dead from Play’n GO

  • The Dog House by Pragmatic Play

  • Deadwood by NoLimit City

  • Dead or Alive from NetEnt (or try Dead or Alive II)

  • Bonanza from Big Time Gaming

  • Jammin’ Jars from Push Gaming

  • Immortal Romance by Microgaming

Ever since the first mechanical slot machines appeared towards the end of the 19th century, they have been an integral part of the casino experience. However, the initial machines were first used in tobacco stores and bars. In the 1960s, Bally developed the first electromechanical slot and released it under the name of Money Honey. The honours to launch the first video slot fell to the Nevada-based Fortune Coin Co. who in 1976 graced the casino world with a monstrous-looking cabinet holding a 19" screen.

Fast forward to the 21st century, and reports indicate that roughly 70% of casino revenue is coming from online slots. Hence, it comes as no surprise that we have today 200+ software providers and game studios vying to be at the top of the pile.

Online slots made their debut nearly a century after their mechanical ancestor. While it was a slow procession at first, the numbers are growing today at neck-break speed with the total surpassing 10,000 titles in 2016. 


New Online Slots in 2020


There is hardly a day going by without an announcement for new online slots, each claiming to be the one with the most sophisticated graphics, best bonus features, and biggest win potential. The well-known reels with fruits, bars, and sevens have long been replaced with a vast array of characters and plots from comics, computer games, TV series, music, movies, fairy tales, and many other equally exciting and vivid themes. Admittedly and probably for nostalgic reasons, there is still a sizeable number of classic slot machines available.

Modern "one-armed bandits" offer developers virtually unlimited possibilities for design, graphics, animations, sounds, and game features. In addition, new online slot games offer a higher RTP (average return to player) than land-based casino slots. While slot machines run in the 80+ per cent range in B&M casinos, their online counterparts offer RTPs around 95 – 97%.

The stream of new online slots hardly ever slows down except for the duration of the summer months as many studios are based in Europe and specifically in Scandinavia, Malta and the UK where July and August are traditional holiday periods. We prowl daily the world wide web and our sources at game providers to bring you an updated list of new and upcoming online slots in 2020:

  • Ocean’s Treasure by NetEnt 

  • Rise of Maya by NetEnt

  • The Wild Hatter by Red Tiger Gaming

  • Troll Haven by Endorphina

  • Joker Troupe by  Push Gaming 

  • Black Horse™ Deluxe by Wazdan  

  • That’s Rich by Play’n GO 

  • PopRocks &ndash by Yggdrasil Gaming 

  • Beat the Beast: Mighty Sphinx by Thunderkick

  • Panther’s Reign, Nero's Fortune by Quickspin 


Free Slots No Download No Registration


For novices and experienced players, it is advisable to try slots for free in so-called demo mode which you can do without any download or registration. All you need to do is pick a slot game you like on sites such as Slotsmillion or Casumo and start playing with fun money. This will allow you to familiarize yourself with the rules, pay tables and mechanics plus to get a feeling on how the game performs. Remember though, all wins are not real money. Should you wish to play slots for real money, you will need to go through a simple registration procedure at an online casino and make a deposit. Online casinos accept payments with a large variety of methods such as bank transfer, debit/credit cards, e-wallets, prepaid cards, cryptocurrency, and others. 

Online Casino Slots FAQ: Get Your Questions Answered!

Below are some of the most common and frequently asked questions, along with advice and the best answers to each.


How to Play Online Casino Slots?


If anyone will ever try to convince you that they can give you the best strategy to play slots start running for the hills. It simply does not exist. What we can do is set a budget what we want to spend, adjust the bet size to a number that will give us the playtime we are looking for and play at a risk level we feel comfortable. 

Should you hit some sizeable wins that elevate your balance to a good value, then increasing the bet size for some time is a risk worth taking as you are not losing any of your deposit, only a part of your winnings. Remember though to start reducing it again if it fails to produce another good win.

The other tip we as experienced players can give is to avoid staying too long on a slot. We all have our favourites where we usually do exactly that as we have the “false” feeling that we know how the slot behaves and that a big win could be just around to corner. Or we have possibly lost a substantial amount, which leads to the typical wrong thinking that the slot must start paying at some point whereas it mostly will not. Should you get the sensation that the slot doesn’t run well, change and try a different one, and change it again if that one gives you the same poor feeling. Just avoid what we call “hammering a slot” in the belief that it owes you and will have to give you that monster win at some point.


How to Find the Best Paying Slots?


An excellent guide to finding the best paying slot is the RTP or return to the player. This is a statistical number on how much a game will pay back to the player in wins over a large sample of spins. Simulations for certification purposes are usually done over billions of spins to determine the average return. 

Generally, the higher the RTP percentage, the more the slot will return to you. Obviously, it can never be 100% as a house edge is built-in to all slot machines that will be the revenue for the casino operators and game providers.
Every slot available at regulated online casinos will display the return-to-player percentage in the paytable or game rules. As a rule of thumb, it is higher than in slot machines found at land-based casinos.

You should look for slots with high RTPs and avoid those with low RTPs to get the most bang for your buck. Make sure to check the RTP values when you load a new game. For example, NetEnt slots feature an RTP in the 95 – 98% range, Playtech is mostly between 92% and 97% while Microgaming features in the 88 – 98% range. However, the lowest value is common to progressive jackpot slots as an additional percentage is reserved for them.

In general, you should avoid playing games with an RTP lower than 95%. Anything more than 96% is today standard for online slots.


How to Win Playing Online Slots?


Slots are by far the most played game of chance at online casinos. They stand out with their simplicity of choosing a bet size, pressing the spin button and hoping for a lucky moment. Still, there has always been the question of whether winning continuously on slot machines is possible or just a myth game providers and casinos are promoting.

Having tracked winnings at casinos over a very long period, we estimate that about every thousandth player will walk away with a big win while a smaller number might manage a small profit. Most players will be happy to break even.

Despite countless stories and so-called guides about winning strategies on slots, there is simply said, none that would guarantee you a win. Slots are games of chance, where pure luck will determine the outcome. Hence, when playing slots, you should not worry about how to win but how not to lose your balance.

In general, slot machines should be seen as a form of entertainment that will cost you money. It is therefore crucial that you determine the maximum amount you are willing to spend and to never cross that line. Equally important is setting a win limit where you get up and walk away instead of squandering it back as you have to remember that you cannot always win.


What Are the Best Online Slots to Play?


Everyone will have to find for him/herself those games that get the juices flowing, the adrenaline pumping and the heart racing. We humans are so diverse, even more so than the vast number of slots can ever be. However, at the end of the day, we all want to play on slots that not only entertain us with engaging gameplay but are also capable of giving us mega and even monster wins.

Below is a selection (in no specific order) which we think are some of the best online slots to play:

  • Montezuma by WMS

  • The Finer Reels of Life by Microgaming

  • Girls With Guns: Frozen Dawn by Microgaming

  • Pretty Kitty by Microgaming

  • Emoti Coins by Microgaming

  • Jurassic Park by Microgaming

  • Dead or Alive by NetEnt

  • Creature From the Black Lagoon by NetEnt

  • 300 Shields by NYX Gaming

  • Lucky Lady's Charm by Novomatic

  • Captain Venture by Novomatic

  • Lord Of The Ocean by Novomatic

  • Cukoo by Endorphina

  • Minotaurus by Endorphina

  • Mongol Treasures by Endorphina

  • Woodoo by Endorphina

  • Book of Legacy by Play’n GO


How to Manage Your Bankroll While Playing Online Slots?


Always remember that online gambling should be fun and entertaining, which at the end of the day will cost you money like anything else in your life. Therefore, sensible bankroll management will avoid overspending and possibly using funds that you shouldn’t. The size of your gaming budget should always reflect on what you can comfortably afford to lose. And best is to determine in advance specific limits, regardless of the outcome of your gaming session. Both losses and wins can impair your judgement. Be it the desire to win losses back or the euphoria after a big win, it can easily lead to even bigger losses.

The Golden Rule: determine your budget for the session or even a single game, and under no circumstances, go beyond it. Decide how much money you can afford to lose and also decide how much you would need to hit the cashout button. Whatever the results are then, after reaching the limits, end the game or session.

It is often hard to stop when you are winning because you might think that this is your super lucky day or when you lose big for that matter. Should you have incurred a loss, exit the casino, relax and keep busy with something else to take your attention off the fact that you lost money. Never try to win back your losses. It is better to come back another day with a clear head and try your luck again.


How to Spot Fake Online Slots?


After more than two decades of internet existence, we all know that anything connected with money will attract fakers. It is not different with online slots and games. Luckily, there is a simple way to find out whether you are looking at an original or fake slot as all licensed slot games are run on specific servers of the game providers. And that no matter if you play in demo or real mode, which is very helpful as you do not need to deposit and play for real money to find out whether the game is fake. Simply open a game in demo mode and follow these three steps:


1. In the game window, right-click and open the Adobe Flash Player settings or click on "inspect" in case a game runs on HTML5 and you will see the server address from which the game loads. Each game developer has its own server, and by its name, you will be able to determine if it is the legit server. 

2. The second option is to right-click on the image of the slot and click on "explore the code" or "explore the item"(depending on browser) in the window that opens. Now you can see from which server the game is loaded.

3. If many slots of different developers are connected to one server, and this server isn't official at least for one of the developers, then it is 100% a fake.

Below you can find the names of gambling servers that are being used by genuine slot game software providers:

  • NetEnt:

  • Microgaming: or also

  • Quickspin: or also If in an online casino are not many "Quickspin slots" then, they can be connected to the Quickfire server. In this case, it must be

  • Endorphina:

  • iSoftbet:

  • Novomatic:

  • Amatic: or also

  • Thunderkick:

  • Betsoft:

  • Yggdrasil Gaming:

  • NextGen: or also

  • ELK:

  • EGT:

  • Play'n GO:

  • GameArt:

  • Habanero:

Are Online Slots Rigged?


In one short and clear word, no. You could ask any player who has been spinning on slots for some time, and they would be able to tell you a conspiracy theory, a dubious spin sequence or chain of events in their session or what they consider clear proof of games being rigged. We call that wearing a tinfoil hat in the player community. Because most if not all that we experience is subjective and not based on data or large enough samples.

Here is an example of a 2019 slot with medium volatility where the developer ran simulations exceeding 200 billion spins before certification:


  • Big Wins: 15x - 1 in 84

  • Super Big Wins: 40x - 1 in 189

  • Mega Wins: 70x - 1 in 444

  • Epic Wins: 100x - 1 in 997


This is done to collect large enough samples as that will supply reliable average data on how a math model of a slot will perform in the long run as well as making sure the game achieves the advertised RTP (return to player).

Now, here you can also see the distribution of larger wins on the slot and their frequency. That, however, does not mean that you will hit them at those intervals. Modern slots are built on complex math models where for each spin an RNG (random number generator) result is called up to determine your spin result. You could go thousands of spins without hitting a super or mega win. Even more when it comes to an epic win. Or you could hit them all in consecutive spins if Lady Luck is on your side.

Fact is that slots have a house edge built-in (online slots roughly 3 – 5%) that serves as the revenue for casino operators, game providers and any other entity involved in bringing a game to your screen or casino floor. At the end of the day, people working for those companies have to be paid a salary. Given that, playing slots will put yourself from the start at a statistical disadvantage.

In essence, slots should be seen as games of chance, and no one should ever think that he or she can outsmart them to get a guaranteed win. It is just not possible, which in itself is the beauty of playing slots. You press the spin button and depending on the luck of the moment you will lose or just maybe hit a huge win. It can all happen in one spin.


What Are Online Casino Slot Tournaments?


A few years ago, slot tournaments and races started to appear at an online casino where players could compete on selected games against their fellow slotters to win extra prizes for finishing in the top of the leader board. They quickly developed into a mass phenomenon, and today you can find them virtually at any reputable online casino. Operators realized that a tournament adds a competitive edge to player experience and embarked on a creative journey that led to a huge variety of tournaments and races being available today. Not only operators but also game software providers have joined in and organize networkwide tournaments where you compete against thousands of players for usually much larger prize pools.

They can run 24/7 or at specific hours, last from just 15 minutes to an entire month and on just a single slot, a group of games or even the entire portfolio. They are named Battle of Slots, Clash of Spins, Reel Races, Rizk Races, Reel Thrill, Champions Races, Slot Wars and other names. The basics are often the same, you will either compete to complete the most spins in a limited time, score the highest equalized win measured in x bet or collect symbols in the fewest possible spins.

Most races and tournaments are free to enter, and prizes are either cash, bonuses or extra spins on selected games. Some casinos have taken the next step and offer buy-in races where you will compete for real money and mostly higher prizes than in free races.

If you want to try your luck in competing against other players below are listed some of the most popular online casinos that offer slot tournaments for everyone:

  • Bitstarz

  • Casumo

  • Bob Casino

  • Slotsmillion

  • Slots Magic Casino

  • PlayOJO


What Does Volatility in Online Slots Mean?


It is common nowadays for game providers to publish the RTP of the games. Still, few are actually disclosing more factual information such as the volatility of a slot, although it will have a significant impact on your gaming experience.

You might ask yourself now what volatility is? In basic terms, it is a measure of how wins are distributed over a large sample of spins on a slot. Low volatility will give you more but smaller wins while high volatility will provide you with less but with the potential to hit bigger wins.

A good indication for the volatility is the pay tables you can access on every slot. Generally, if the difference between hitting two or three and five matching symbols is large then it is very likely a high-volatility game. The opposite applies for low volatility. The example below shows one instance of each.
