Best Slot Websites 2021

Competition among online slot websites is getting fiercer every day and every online operator tries to allure new visitors by offering something special. Some casino websites try to show off with stunning portfolios, others offer welcome packages that are hard to resist, while most slot sites try to do both and even add a bit extra. Either way, heavy competition in the industry has turned out to be very beneficial for players.

Betsson is not only focused on online slots, but also features a sportsbook and a poker platform. With new slot games added to their portfolio every week, Betsson houses a refreshing assortment of slot entertainment including +1100 games.

Should you fancy a specific game provider like NetEnt or Play’n Go, you will be most likely to find what you’re looking for as they’ve teamed up with more than 25 slots developers.

“Anytime’s playtime”

Something we highly enjoy at Betsson is that they offer amazing jackpot slots. There are about 150 different jackpot games available with price pots of all sizes. A lot of the jackpots you’ll find here are daily jackpots guaranteeing daily hits. What makes Betsson stand out from its main competitors is that it has been around since 2001 and still offers the perfect combo of slots, live casino games, and a sportsbook.

Like Betsson, Betsafe is also owned and operated by BML Group, explaining why it has managed to grow out to one of the most successful betting brands in the online casino industry.

CasinoEuro was launched in 2002, making it one of the most experienced slot casinos you’ll find on the internet. It’s also considered one of the most trustworthy casino websites in Europe, because it has managed to outweigh its competitors in a very competitive industry. Although it’s been around for a while, it has successfully managed to adapt its platform to today’s standards which is why the website is both user friendly and full of games. The collection of slot games is bigger and more beautiful than portfolios offered by its main competitors. CasinoEuro gives you the world’s best slot games, a large live casino, award-winning customer care, and easy transactions. Who owns CasinoEuro? BML Group.

“Europe’s best online casino”

CasinoEuro dares to call itself Europe’s best casino and in order to do so you’ll need to have both experience and a large assortment of casino games. Luckily, CasinoEuro has both of these. With +1200 slot machines most players will find all the games they enjoy playing when making a wager in a real money casino. Games developers you’ll come across on this website are NetEnt, Microgaming, and Evolution which explains why you’ll find a lot of quality on this website as well. The good thing is that there are plenty of lesser known providers as well, giving players a chance to discover new slot games they would’ve missed elsewhere.

4. VideoSlots

There are a few gaming capitals in Europe and Sweden’s Stockholm is definitely among them, while the same is true for Malta. VideoSlots was launched in 2011 by a few Swedish gambling experts who teamed up in Malta and came up with the idea of opening a new casino. More than a decade later Videoslots is still considered one of the most popular online casinos and this is mainly thanks to its grand portfolio counting +5000 casino games. Although we do think their website needs an upgrade, the games on offer will give you all the options you need to enjoy online gaming — including a lot more than just slot machines.

“The home of video slots (and more)”

To illustrate our point here: we write a lot of casino reviews, but we don’t come across a lot of casino platforms that house 112 game developers. With new games added on a weekly basis, you’ll probably understand why Videoslots.com has turned out to become one the preferred casinos among a lot of slot enthusiasts. Apart from its many slot games, you will also find a lot of table games and live dealer options in its lobby. We counted about 340 live casino productions which is also above average when compared to other casino websites. In terms of quantity and quality, it doesn’t get a lot better than Videoslots Casino’s library.

Launched in Malta as well and holding offices in Barcelona and Gibraltar, Casino Casumo has drawn a lot of attention ever since it opened in 2012. Casumo is a complete online casino and sportsbook services company that includes a full range of gaming products featuring casino games, jackpot games, live casino, table games and other betting products. The brains behind Casumo have a lot of experience in the gaming industry which is why this casino has managed to become one the most popular betting platforms within a relatively short period of time. Being awarded as the Rising Star and the Mobile Casino Innovation Award we believe there are quite a few reasons why you might want to consider Casumo.

“Erase Boredom” & “Never Grow Old”

Casumo’s game portfolio is very extensive which is the direct result of this operator connecting with the world’s biggest developers. This is also why you will find hundreds of slot machines in its main game lobby, including many popular and high profile slots like Starburst, Gonzo’s Quest, Bonanza, Book of Dead and many others. They also feature a lot of exclusive productions that aren’t available anywhere else, as well as some very rare slots games that you won’t find in many other online casino websites. With a growing game selection of nearly a thousand titles, you will be unlikely to ever run out of gaming options.

What makes a slot site stand out? 

New online operators enter the highly competitive online casino landscape everyday giving players a lot of options. Although having some options is always good, a superabundance can be a bit overwhelming to some players. This is why we have evaluated and mapped out all the casinos entering the market. We only include the very best ones on our website after they managed to pass the test. Our main objective is to suggest online casinos that hold the best licences and work with the best partners — which is basically a well balanced blend of proper software developers and banking methods. We believe in a lot more than bonuses only and we highly appreciate slot sites that offer fair terms, in addition to a safe platform.

Slot games: so much more fun online

Online slots are a very convenient gaming solution as they bring the casino excitement right into your living room. The gaming experience has become a lot more realistic over the years, which is why a lot of gamblers have shifted their attention to online operators rather than physical casinos. Convenience is not the only reason to move to online alternatives as online casinos usually offer better odds and better jackpots. The reason for this is pretty easy to understand as online sites employ less staff and don’t require a lot of space to offer their services. This is one of the reasons online casinos can afford to hand out bonuses, something a land based casino would never do. At online casinos you won’t be restricted to opening hours and all you’ll need is a device, an internet connection, and some funds.

How our slot sites are reviewed

The main idea of our online slots guide is to help you get the most out of your online casino experience. In order to do so, we believe the ultimate experience is about finding the perfect balance between a user-friendly website, welcoming casino bonuses, outstanding gaming collections, and a safe and secure platform. All the casinos that are featured in our top list tick the boxes and will make sure you’re about to have an excellent experience. Some of the criteria taken into account by our dedicated team of casino professionals are:

Trustworthiness

Online gaming is great fun and this is how playing online should be experienced by every player: as a fun activity. Although it’s hard for us not to share our enthusiasm, we will not fail to point out the risks of certain games or casinos. At the same time, we will only feature casino websites if we strongly believe that their platform can be considered trustworthy. This trust related factor can be divided into a few subcategories, which we’ll briefly address:

  • Website security: web security is one of the most important features to take into account when evaluating an online casino site, as most people sign up for an account and transfer money to and from their online account. As a player, you want to have peace of mind that your financial information is safe, not to mention any other personal data that you have entered when signing up to the casino website. In order for you to get a trouble-free casino experience, your preferred casino should take great responsibility for protecting its customers’ data. Luckily, we have put the online casinos we recommend to this test and have concluded every one of them employs advanced security systems and technologies ensuring a high level of protection.
  • Licence: this is also why all of our recommended online casinos hold valid casino licences issued by gaming authorities like the UK Gambling Commission (UKGC), the Malta Gaming Authority (MGA), the Gibraltar Regulatory Authority (GRA) and Scandinavian licences like the Swedish Spelinspektionen and the Danish Spillemyndigheden. Holding a gaming licence stands for consumer protection.
  • Reputation: choosing an online casino which is both reliable and reputable is a must if you want to get a smooth gambling experience from playing a casino game online. Reputation, however, is earned over time and well performing new online casinos might score well on certain criteria, but this doesn’t make them yet reputable. Brands that were launched by experienced online casino operators do have a lot of benefits in comparison to casinos that aren’t.

Game portfolio

If you’re someone who usually plays at land based casinos, you’re probably used to having access to a rather limited number of games as brick and mortar venues have a fixed floor space to stall their slot machines. Clearly, this is less of a problem for online casinos which is why you’ll find online casinos offering hundreds and often even thousands of games, all on one domain. On the internet, you’ll enjoy an unlimited number of slot machines to try with new launches added regularly. Other than a large slots library we find it very important that a complete casino offers table games and a live casino as well. Ideally, you would have all sorts of casino games under one roof, maybe even a sportsbook and bingo games.

Bonuses

One of the most lucrative parts of joining an online platform over a land based casino is that most casino websites will give you a welcome package. A lot of licenced casinos are pretty similar these days, which means that a proper casino bonus can actually make the difference for players to prefer one casino over another. To differentiate from the crowds and to lure players in, casino websites will come up with all sorts of welcome offers, usually via deposit bonuses, free spins, or a combination of both. A generous welcome bonus is a must for any reputable online casino. This is particularly true when it comes to slots, so you can get in plenty of extra spins. All our top-rated sites offer great casino bonuses for a smooth start of your online slots experience. Most of them have promos for existing players too.

Payment methods

Choosing a proper payment provider is quite a challenge as there are lots of options to choose from, and each banking method has its pros and cons. You might want to consider using a separate banking method for your online casino funds as this will give you the opportunity to track your transactions easily and control your spendings. Banking methods at online casinos can be divided into two groups: those for depositing funds and those for withdrawing money. Although some methods offer both options, we’ll take a look at them: 

  • Deposits: to give you a full understanding about the banking method our recommended casinos work with, we will always list the banking methods offered by the online casinos. The best payment option is the one you feel most comfortable and familiar with, but allows you to deposit funds and withdraw winnings in a fast and free way. Speed affects your overall gambling experience, while fees will affect your net revenue. Picking a deposit method may also affect the validity of bonuses.
  • Withdrawals: working with the right banking methods can also affect the withdrawal process as some payment methods offer instant payouts (most e-wallets), while others require more processing time (bank transfers or credit card payments). A good online casino gives its players some flexibility to pick a payment method that he or she feels most comfortable with. Do note that a lot of casinos require their players to use the same withdrawal method they have used for making their deposits. Most casinos work with withdrawal limits which is also something important to take into consideration. Our casino reviews look into everything with regard to casino banking.

Web Design

Casinos have massively shifted to the internet in recent years and one of the main challenges is to make visitors feel at home. As websites have evolved over the years, online casinos have managed to become more and more realistic, offering game portfolios that are easy to scroll through. If you bump into a well designed casino, you can expect smooth gameplay, realistic sound effects, and neat graphics. This should make your overall casino experience a lot more enjoyable and will probably make you come back for more. Although some casinos are visually more appealing than others, most of our casinos get selected by their looks as well and you can’t blame us. In the end, a pretty face does make a difference.

Customer support

Most new casino players don’t even think of customer support when they go about finding a proper online casino. It may not be something that occurs to most players until they actually need to contact the service desk, and by then, it’s too late if you’ve picked the wrong casino site and deposited your funds. Our expert reviews can tell you how to get in touch, what sort of service to expect, and the opening hours the online casino works with. Usually, the faster the support is, the better. That is why we can’t stress the importance of 24/7 support enough.

Mobile experience

The best online slots sites will bring a myriad of thrilling gaming experiences directly to the palm of your hand. This is clearly very convenient for casino players, as you can play the very best megaways games, 3D-productions, progressive jackpots and branded slot machines while lying in bed, sitting on your couch, or standing in the tube. More and more players make a wager while they’re on the go and that’s why we also evaluate the mobile experience. Some of our listed slot sites even offer better mobile experiences than their desktop counterparts. Ideally, we look for superb mobile sites without needing to download an app.

Different type of slot machines to play online

Online slot games are soaring in popularity across international online casinos by giving players world class entertainment, bundling outstanding gameplay and chances to win million dollar prizes. Today, punters have a sensational array of online slots at their disposal, ranging from traditional 3-reel and 5-reel slots to Megaways games and progressive jackpot slots. Whatever kind of online slot games you’re looking for, low or high volatility, we always advise you to check out your options in each category and have came up with a full list:

Slots

Slot machines have rapidly shifted from pubs and brick and mortar casinos to online casinos and the online versions have actually managed to take over and dominate the world’s slots industry. Online slots include the traditional 3-reel and the more advanced 5-reel slots, of which the latter are known for offering players thrilling features like wilds and scatters, with interactive themes and visuals to keep you entertained for a much longer time than their predecessors. But there are completely new variants of online slot games as well. In this section we will stick to the traditional slots after which we will discuss some other variants.

 

Gonzos-Quest-slot

Gonzo’s Quest (NetEnt)

There are 7 different Mayan themed symbols in Gonzo’s Quest and the idea is to line up 3 to 5 identical symbols on a payline. The blue and gold face in this NetEnt production pays up to 2500x your stake for 5 of a kind.

Book of Dead slot

Book of Dead (Play ‘n Go)

Egyptian themed slots are always hyped, but slots that payout 5000x your stake per betway are even more hyped. In Play’n Go’s Book of Dead, adventurous punters will go on a quest to unravel old mysteries and reveal their riches.

Starburst

Starburst (NetEnt)

NetEnt’s Starburst isn’t considered revolutionary and it’s no rocket science either trying to figure out how the game works. Maybe that’s why it’s so popular. Starburst features everything a slot game should have.

Wold-Gold

Wolf Gold (Pragmatic Play)

With the different jackpots and the medium variance, Wold Gold will always give you the feeling that there’s always something about to happen, even though you’re in a desert. Wolf Gold is one of the world’s most featured games in trustworthy online casinos.

Jackpot slots

Progressive slot games are extremely popular amongst online slots players and any jackpot game aims at attracting customers with lucrative rewards and we have to say — they’ve been most successful in doing so. Jackpot slots are designed in such a way that a portion of every wager contributes to a huge jackpot pot leading to massive jackpots within a short period of time. That’s why some of them pay out millions of pounds which is a lot more than their offline counterparts in land based casinos. Some of them have even broken world records as you’ll find out below.

 

Mega Moolah slot

Mega Moolah (Play’n Go)

Mega Moolah holds the Guinness World Record for the biggest jackpot ever paid and it has managed to break its own record several times. It has paid out jackpots of more than $20 million which is why this game is still very popular — even 15 years after its launch in 2006.

Mega Fortune slot

Mega Fortune (NetEnt)

Mega Fortune is also considered to be one of the best jackpot slot games ever launched. Although its popularity has dropped a bit in recent years, this NetEnt production still manages to pay out millions of dollars/pounds — even with bets as low as $0.25.

Mega Fortune Dreams slot

Mega Fortune Dreams (NetEnt)

NetEnt followed up Mega Fortune by producing Mega Fortune Dreams. The slot continued with its 5×3 grid and 20 pay lines, but offered increased volatility, better features and a graphical upgrade — making Mega Fortune Dreams one the most played progressive slots.

Arabian Nights slot

Arabian Nights (NetEnt)

In Arabian Nights, provider NetEnt takes us to a world of colourful fezzes and pointy satin slippers. A world as imaginative as this one will of course need a progressive jackpot. Arabian Nights’ jackpot has paid out millions of dollars ever since it was launched.

Megaways slots

Megaways slots were first introduced in 2016 by Big Time Gaming when Dragon Born Megaways was launched as the first-ever Megaways slot. Funnily enough this slot game didn’t get a lot of attention, which was also the case for the next two Megaways slots, Starquest and Queen of Riches. It was not until BTG released Bonanza Megaways in that same year when players started realising the shift from a fixed number of paylines to infinite ways to win was hard to resist. Below you’ll find the best Megaways slots available online.

 

Monopoly Megaways slot

Monopoly Megaways (Big Time Gaming)

Monopoly Megaways gives a new twist to the already popular game theme giving the punter 6 reels and 117,649 ways to win. Monopoly Megaways has 4 bonus features including cascading reels, reel adventure feature, free spins, and an unlimited win multiplier feature.

Bonanza Megaways slot

Bonanza Megaways (Big Time Gaming)

Big Time Gaming’s breakthrough as a gaming company is largely thanks to Bonanza Megaways, as we pointed out above. A goldmine, two sets of reels, a Banjo soundtrack and 117649 ways to win is all it takes to create a new hype that stands until the day of today.

Extra Chilli Megaways slot

Extra Chilli Megaways (Big Time Gaming)

This game is considered Big Time Gaming’s successor for Bonanza Megaways, including some visual upgrades and the addition of a Featured Drop and a RTP-increase in the RTP. Winning symbols are replaced by new ones, making sure to keep you on your toes with re-spins as long as you manage to spin winning combinations.

Holy Diver slot

Holy Diver (Big Time Gaming)

When we thought it was impossible to come up with something new around the Megaways mechanism, BTG came up with Holy Diver Megaways: combining megaways with the Reel Adventure concept. Exciting as it sounds, this game gives you a whole lot of options to win, including wilds and stacked wilds with multipliers.

3 Reels slots

Following the first-ever slot machine produced in California in 1894, the first 3-reel slot machine with automatic payouts was launched 4 years later, in 1894. This is said to be the schema where all fruit slots were based on — including digital slot games as online technology took land-based slot machines to online casinos with time. Online 3 reels slots gave providers the opportunity to experiment with 3-reel slots in all sorts of ways. Traditional 3-reel slots are especially great for new players as they are very simple to learn and don’t come cluttered with difficult to understand bonus features. The best 3 reels slots include:

 

Mega Joker slot

Mega Joker (NetEnt)

Mega Joker is an iconic NetEnt-production and is one of the rare slot games that comes with a high volatility and an extraordinary high payout percentage of 99%, which is a dream combination for pretty much any slots enthusiast.

Lightning Joker slot

Lightning Joker (Yggdrasil)

If there’s one game developer in the online casino industry with a vision to reinvent a classic 3-reel slot, it’s Yggdrasil. Lightning Joker is one of the best examples of how a 3 reel slot slot delivers both excitement and rewarding gameplay.

Diamond Duke slot

Diamond Duke (Quickspin)

Produced by Quickspin, the Diamond Duke slot game graphically embodies a classic jukebox. This 3-reel slot gives you wheel scatter symbols, a bonus wheel and a multiplier wheel.

Hot Chilli slot

Hot Chilli (Pragmatic Play)

Hot Chilli comes with an Asian theme (the other option would be Mexican) in the form of a giant bubbling hot pot containing Asian foodstuffs and reward symbols. The main ingredient? Red chilli.

5 reel slots

As you’ll understand by now, 3 reels slots were followed by 5 reels slots which means you can count on extra features to make the slots even more fun to play and rewarding. The biggest difference between both is that 5 reels slots, aside from giving you some more reels, also come with interesting bonus features and slot themes. Often you’ll find films and TV shows to be based on 5 reels. This also explains the graphical upgrade in comparison to 3 reels slots. Some of the 5 reels slots below have managed to become all time slot classics.

 

Dead or Alive slot

Dead or Alive (NetEnt)

As one of the most iconic slot productions in NetEnt’s game portfolio, Dead or Alive will make you explore the wild west. This game was launched in 2013 and comes with sticky wilds and an amazing free spins feature.

Blood Suckers slot

Blood Suckers is as scary as it sounds, but if you dare to step inside, you will see how the gory dungeons are stacked with spooky bonus features. The scary bride will lead you to the free spins round where only the brave can trigger 10 free spins with a 3x multiplier.

Esqueleto Explosivo slot

Esqueleto Explosivo (Thunderkick)

Immortal Romance slot

Immortal Romance (Microgaming)

Immortal Romance is probably one of Microgaming’s most played slot games. As in anything vampire, this popular slot game means serious danger, darkness and bloodlust.

243 ways

Traditionally, one would slot a coin into a so-called one-armed bandit and the symbols on a single payline across 3 reels would decide if you’re lucky or not. With the introduction of the best slot websites, slot games continued to evolve, coming up with all sorts of mechanisms. A lot of the newest generation of online games give players more than 243 ways to win on a single spin. We won’t bother you with the math behind this concept, but the main thing you’ll need to remember is that you’ll now get 243 ways to make a winning combination.

 

Narcos slot

Narcos (NetEnt)

The plot of this popular slot game is based on the Netflix series Narcos and even uses the same name. This branded slot game gives you a lot of thrills, including great visuals and audio and big prizes you can win in 243 different ways.

Avalon II slot

Avalon II (Microgaming)

Avalon II is yet another popular title by Microgaming that works with 243 ways to win. Avalon II is played on 5 reels and was clearly inspired by King Arthur’s story and the pursuit of the Holy Grail.

Penguin City slot

Penguin City (Yggdrasil)

Penguin City is a signature slot by Yggdrasil slot, introducing a separate bonus game and on top of that, you can win 1,647x your stake, even though this is a medium variance game.

Bonus buy slots

The bonus buy option (also known as feature buy or buy a bonus) was first integrated into a slots game in 2017 when Big Time Gaming’s White Rabbit was launched. The buy a bonus feature was meant for players who didn’t want to wait for the bonus round and instead had the opportunity to buy themselves access to the bonus feature. This is a lot more expensive than activating a bonus via the basic game, but it does help you save a lot of time and effort. Buy-a-bonus features are becoming increasingly popular and more and more slot makers have decided to let players decide for themselves if they want to earn their way to the bonus features or if they want to take the shortcut and buy themselves access to the bonuses.

 

Money Train 2 slot

Money Train 2 (Relax Gaming)

Relax Gaming has done pretty much everything right with this sequel to the original Money Train game. Part 1 was already a volatile beast with a 20,000x win potential, but this popular sequel will make you win even more: up to 50,000x your stake that is.

Starburst XXXtreme slot

Starburst XXXtreme is the first official successor to the timeless classic that was released in 2013 and still tops slot lists across the world. Random multipliers up to x150 per expanding wild can give you insane payouts of up to 200,000x.

Punk Rocker slot

Dead or Alive 2 slot

Dead or Alive 2 (NetEnt)

The original Dead or Alive launch celebrated its 10 year anniversary in 2019, and what could be a better celebration than Dead or Alive 2 giving players a free spin option and bigger prizes. Dear or Alive 2 is just as popular as part one which isn’t always obvious.

Low volatility

Slot games come with a certain volatility and the biggest difference between low volatility games and high volatility slots is basically the amount of money you have to wager to gain a payback. While low volatility slots will give you hours of gaming fun on a tiny bankroll, payouts will be frequent, but smaller — which can be a reason to stick to low variance slots for some. The best low volatility slots will require few coin stakes to achieve them. Some examples of popular low volatility games are:

 

Bloodsuckers II slot

BBloodsuckers II (NetEnt)

Bloodsuckers II features all the popular features and characters of the original version and 5-reels, and 25 pay lines, along with scatter symbols, wild symbols, and multipliers. Just make sure you’re prepared for a lot of blood shedding in this production by NetEnt.

Enchanted Garden II slot

Enchanted Garden II (Real Time Gaming)

This slot by Real Time Gaming is quite an improvement of its predecessor in multiple ways. The Wild Fairy Princess will help you make your wins by replacing symbols and doubling your payouts.

Wild Scarabs slot

Wild Scarabs (Microgaming)

Released in 2018 by Microgaming, Wild Scarabs is an Egyptian themed slot with low variance that will boost your winning chances. The Scarab Wild is the one you would really want in this game as it can land after a losing spin triggering the Wild Deal bonus feature.

1429 Uncharted Seas (Thunderkick)

This Thunderkick slot machine has great graphics as well as expanding wilds and a thrilling bonus game. Along with the designer team’s creativity on show, your budget will last a lot longer on this one.

High volatility

Despite its high costs, high volatility slot games are actually among the most sought after as they pay out the biggest bucks. Also referred to as high variance slots by some slot sites, they are especially preferred by high rollers giving players the ultimate casino thrills. High volatility slots are widely available at all slot websites and there is a wide array of such titles on offer. You’ll need to be prepared that high volatility slot games can go dry for long spells without paying out and you’ll need a bigger bankroll and some patience. But when games with a high volatility do finally pay out, the wait will be well worth it.

 

Book of Ra slot

Book of Ra (Novomatic)

Book of Ra is one of the first high volatility titles that fully deserves to be on any list. Launched by provider Novomatic, the adventurous slots game Book of Ra is known to be the king of high volatility slots with legions of loyal fans.

WMS Gaming’s Raging Rhino takes high volatility slot games to another level with 4,096 ways to win a payout after every spin. With wild multipliers that hit 6x your stake, and payouts of 3000x your stake, Raging Rhino is a high variance slot you will need to play.

Jammin’ Jars slot

Jammin’ Jars (Push Gaming)

With multiple slot features and a maximum payout of 20,000x, Jammin’ Jars is one of the most popular high variance slot games out there. For the biggest payouts, you’ll need to wait for the free spins round in this retro game by Push Gaming.

Joker Troupe slot

Joker Troupe (Push Gaming)

A massive potential payout of 25,367x awaits you in Push Gaming’s magical Joker Troupe. The large payout potential, the high maximum bet size and the fantastic slot features, all explain why Joker Troupe is a must play game.

RTP slots

If you’re all abou getting the most out of your stake you will probably know already what we mean with RTP. The RTP stands for the Return to Player which gives punters a better idea of what their investment will return in the long run if they would play a particular game for a longer period of time. The RTP is normally presented as a percentage which is the easiest way to reflect the theoretical winning rate of a game. If a slot game has a RTP of 97%, this is what you’ll get back in wins out of every 100 sessions. If this would be put into a monetary context, it would mean you would get back $/€/£ 97 out of every $/€/£100 — that is in the long run. The RTP can be seen as an average and doesn’t account for volatility and the possibility of big wins when you make a low number of first spins. For budgetary purposes it is always a good idea to take into account the RTP of a slot game, including options like:

 

Goblin’s Cave slot

Goblin’s Cave (Playtech, 99,32%)

Make sure to bring along your torch and watch out where you walk as you’re about to descend into Goblin’s Cave. Luckily, this cave is fully packed with golden coins, gem-encrusted crowns, beautiful rings and other valuable riches. The other good thing is that this Playtech production comes with an insane RTP of 99,32%!

Ugga Bugga slot

Ugga Bugga (Playtech, 99,07%)

This jungle adventure is different from all the other jungle escapes you’ve seen so far. Playtech’s 2013 Ugga Bugga production gives players wilds across the reels for a maximum payout of up to 1,000x your stake!

oh Aah Dracula slot

Ooh Aah Dracula (Barcrest, 99%)

Ooh Aah Dracula (yep, this is the real name) was launched in 2015 and includes a lively soundtrack to match its somewhat weird design. The game works with a 5×3 reel set and has 10 betlines, wilds, a medium volatility and a lot of free spins and more.

Book of 99 slot

Book of 99 (Relax Gaming, 99%)

No, this is not a typo: while many slots work with RTP’s ranging between 96% and 97%, Book of 99 gives you a theoretical payout percentage of 99%. The ‘99’ also refers to the number of book symbols you need to collect to trigger the extra bonus round.
