Game reviews with RTP in focus
If there's one thing we enjoy more than thrilling slot games, it's slot games that…
Online casino sites have a whole lot of competition to bear with which is why they try to think of all sorts of ways to outperform their online rivals. One of the ways of doing this is by offering bigger portfolios than other websites which is why there are online casinos that have catalogues with thousands of games. The vast majority of games offered online are slot sites and the same is true for the bonuses available. Although especially live table games are becoming increasingly popular, online casinos are still evaluated according to their offer for the slot machine minded.
Punters looking for slots to make a wager on are therefore spoiled with choice and whether it’s a traditional slot game or a Megaways game they’re looking for, there should be enough options available — both in terms of titles and bonuses. With thousands of casinos, thousands of slots, and thousands of promos, it can be a bit tough to make the best pick out of all those options. In order to save you a lot of time, we are more than happy to tell you more about the things you should think about when choosing your next best slot site. And we’ll also give a list of our own list of favorite websites for slots.
The iGaming industry is extremely fast paced, with new operators opening their virtual doors non stop. This won’t surprise many people as the internet is limitless, making most websites available from most places in the world. Out of all the new casino sites that are available to players in the UK and were launched in recent years, there are a few websites that have managed to stand out from the rest. Sticking to these websites will make sure you will sign up at the best slot sites available to UK players, meeting criteria such as licencing, games assortment, bonuses, and customer service. Here’s our latest top list:
Betsson casino is without a doubt one, if not the one, leaders within the online casino. No other casino brand offers this large range of slots, table games together with massive promotions. With Betsson - you can't go wrong!
Videoslots casino comes with over 3000 games and a wide horde of online slots. Treat yourself to some exciting casino action, all in one place. With so many games, it means more jackpots and more fun!
Rizk is a highly popular and vibrant superhero-themed casino. The mascot, Captain Rizk, fights shady deals and promises “real rewards, no bullshit”.
When referring to the best slot sites, we select our recommended online casinos using a wide array of performance metrics that are manually checked by one or multiple slots experts. All of the games and casinos we review at CasinoWebsites.com are evaluated with real money play with the main objective of covering the following list of metrics:
The best online slots websites cover the full spectrum of offering a thrilling experience on any device. This usually includes desktop and mobile as these are the two most used devices to make a wager on. The latter group of mobile users has grown significantly in the last few years which is why most online casinos have optimized their websites for mobile play. Virtually all casinos we include in our top lists offer fully optimized websites and game assortments for mobile action. Whether it are regular slots, or Megaways games you’re looking for; it doesn’t really matter when, how, and where you access the games you want to play, online casinos are available 24/7 on all latest devices like desktops, laptops, tablets, and mobile phones.
The payment methods often get overlooked by players who tend to pay more attention to bonuses or games offered by the casino. Payment methods do make a huge difference as they all have their own pros and cons when it comes to processing times and fees. Some of them are even excluded for bonuses, so casinos that offer a wide array of banking methods are highly valued by our slots experts. Ideally, you would be able to play your favourite slots game and use your favourite banking method at the same casino. Payment solutions can be divided into two groups: those for making deposits and those for making withdrawals. Taking a closer look at the different sorts of banking methods, slot sites offer:
Most slots sites that are available offer a welcome bonus to players and some of them offer other promos as well. Bonuses are one way to welcome new players and make frequent players feel at home. Most of these promos are valid for slot games. Our slots professionals have also gone through the other terms and conditions to make sure that the bonus is fair and feasible. Promos for slots come in different forms, but the most common bonuses you’ll come across are match bonuses, free spins, cash backs. In addition, some casinos work with loyalty programs and VIP programs. Our top rated slot sites offer bonuses in order to give you an easy start of your slots experience.
Ideally, you would never need to contact customer support, but if you’re a frequent player or you expect yourself to make frequent bets, you would want to sign up at a casino that delivers a level of support you would expect from any service provider. We believe that the best slots sites are those that offer a complete experience which clearly includes solid customer support. In order to save you some time we have made sure to contact the support departments of our recommended casinos and we assure you that we do everything to give them a hard time and see how they cope with it. We’re looking for casinos that are both prompt and professional and we bet that you would be looking for the same features.
Online casinos were once known as dodgy and we can’t deny that there are still some no-go casinos to be found on the internet. Luckily, online casinos nowadays work with licences that are issued by governmental authorities which gives consumers a lot more grip when it comes to looking for stable websites. Things have gotten a lot easier for players: markets are now regulated, casinos have licences like webshops have quality mark certificates, and internet users are more and more capable to recognise what a safe website looks like. This also explains why casino security can be the following categories:
Slot games are among the easiest games of chance you’ll find on the internet although they may seem a bit confusing to some with all the flashy lights and spinning reels. If you’re familiar with land based slot games then you’ll get the idea of how to play slots. Online slots also work with a Random Number Generator (RNG) which pretty much does what the name says it does: it generates random results. This means that there is nothing or nobody that can affect the outcome of a spin: neither the casino, nor the player. You’ll therefore fully depend on randomness which is reassuring to know as that’s what makes playing on slot games so much fun. Despite not being able to influence the outcome of this game of chance, there are a few ways to increase your return on investment and lower your unnecessary expenses. Here is some useful info when it comes to how to play slots:
We know, there are lots of slot machines available and while they theoretically do the same thing, they have a different way of presenting the game to their players. You’ll find all sorts of slot machines on the market and they differ in grids, winlines, mechanisms, features, reels, and themes. You might want to consider starting with the easy ones first and stick to the free mode (which we’ll discuss later on) to avoid losing money because you didn’t understand the ins and outs of the game shown on your screen. Here are some characteristics to pay some extra attention to when playing your next slot machine:
The payout percentage is often referred to as the RTP which is a percentage that basically shows you how much money you could expect in return if you would make a large number of bets. This percentage shows you how frequent a slot game pays out in the long run and the idea behind is fairly: the higher the percentage, the more likely your chances of winning in the long term. A RTP of 94% means that you would earn £94 out of every £100 you bet with. The RTP should be clearly displayed on usually ranges anywhere between 93% and 99%. As this is a theoretical percentage that works with long term data, short term differences are common. This also means that the more you bet, the more accurate the RTP will be. Our advice? Stick to games with the highest return to player (RTP).
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%!
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!
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.
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.
Often confused with the RTP, all slots also have a certain volatility which can be anything from low to extremely high. Most comparison websites would use the low to high scale while some sites also include numbers from 1 to 10 to clarify their point. The main difference between low volatility and high volatility games is the amount of money you will need to wager to make a win. Low volatility games are known to give you hours of fun and require relatively little money, while high volatility slots suck up your budget without you noticing it. The difference between the two is that low volatility slots typically lead to small wins and high volatility games generate major wins. High volatility games, which are often referred to as high variance slots, tend to be popular among high rollers. You’ll need to bear in mind that high volatility games can go dry for long spells without a win which requires both budget and patience. But when they do pay out, they pay out big time.
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.
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.
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.
Big wins are often facilitated by slot providers who come up with maximum potential wins. They are also the ones that think of themes, do the graphical work, and think of the number of paylines integrated into the game. This brings us to our next topic as the game developers a slot site works with hugely influences whether a casino has a strong catalogue or not. Players who are based in the United Kingdom will often find casino games that are produced by providers like NetEnt, Playtech, Microgaming, and Play’n Go which are also the names we would list when we think of our favourite developers. It has been largely thanks to the game developers that the casino industry has managed to become what it is today. Some of the game providers that make a difference are:
|Microgaming||Microgaming was founded in 1994 and is still one of the biggest brands you’ll find online. Some would even list Microgaming as the biggest name in the industry. One of the reasons for Microgaming’s popularity is the wide availability of the Mega Moolah jackpot game which is considered the number jackpot slot in the world. It has even managed to be listed in the Guinness Book of World Records.|
|Play’n Go||Play’n Go has also been around for a while as they were launched back in 1997. Since the nineties they have been working on a wide array of all sorts of games for online casinos and their partners. This includes slots, but also table games. Most players in the UK looking for the best slots sites will probably be after games like Reactoonz and Book of Dead. A lot of casinos offer free spins for Book of Dead.|
|NetEnt||By many players, NetEnt is still considered iGaming's biggest brand, but things have changed in recent years as they were bought by Evolution in the summer of 2020. Nonetheless, there are still new games released by NetEnt which is especially the case for slot games. Some of the most popular games ever released were produced by this Sweden based provider. This includes the games of Gonzo’s Quest and Starburst.|
|Pragmatic Play||Pragmatic Play is one of the best things that has happened to the online casino industry as it has taken on any challenge in pretty much any category. Whether it’s jackpot slots, regular slots, table games, or live dealer games: Pragmatic Play has developed multiple titles in each of the categories. With at least 5 new games a month we expect Pragmatic Play games to be featured by the best slots websites. This should include at least games like Wolf Gold and Big Bass Bonanza.|
|Yggdrasil||Yet another Sweden based game developer, Yggdrasil is considered one of the most remarkable names in the casino sector which is mainly thanks to their different approach of picking game themes. Yggdrasil tends to stick to Nordic themes which is something a lot of players will enjoy as a top Viking game really never gets old. This is why a lot of players love titles like Vikings Go Wild and Orient Express.|
|Nolimit City||Not yet considered one of the top players, but definitely one of the most remarkable names in recent years. Nolimit City has shook up the industry by launching game themes you won’t see at other developers. Add major potential wins and features like xNudge wilds, xWays, and the Reel Split feature, and you’ll understand why people are loving everything this provider launches. They’ll get there.|
|Playtech||Isle of Man based Playtech is seen as one of the most skilled game developers as they’ve shown they know how to produce all sorts of games. This doesn’t limit to slots only, but you can expect poker games, platforms for sportsbook, bingo rooms, and even scratch cards as well as this is all delivered by Playtech. When sticking to slots games only you might just have heard of Suicide Squad and Top Gun. These successful games were produced by the Paytech team.|
|Big Time Gaming||Big Time Gaming has been responsible for one of the biggest revolutions in the online casino industry when they launched their
Megaways mechanism. This mechanism turned out to be so popular amongst players that BTG started selling licences to produce Megaways games to other providers. Nowadays, virtually all big game developers have launched their own Megaways games, but only after having bought their licence from Big Time Gaming. Now that’s what you call doing business. Games by Big Time Gaming include Bonanza and White Rabbit Megaways.
Slots are the most popular type of casino games you will find in any online casino and this is all thanks to their first class entertainment, outstanding graphics, and chances to make major wins. Nowadays, players from all over the world have thousands of options when it comes to slots and it might be hard to make a choice with all the titles that are available. In order to give you a better idea of the type of slots, we believe it might help to categorise them into a few separate groups. This should give you a better idea of what’s on offer:
Slot games rapidly moved from traditional pubs and land based casinos to their online counterparts meaning the games have also reinvented themselves. Traditional online slot games are online versions of the fruit machines most people are familiar with in land based venues. Traditionally, slot machines were launched as 3-reel games, but nowadays there are 5-reel slots as well.
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.
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.
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.
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.
Probably the most popular category as the progressive jackpots can hit millions of pounds. The progressive jackpots are even more sought after as these are set up in such a way that every penny spent becomes part of a huge jackpot that can reach big numbers within a short period of time. This is quite logical if you ask us, as players from all over the globe make their contribution to the jackpot. Online jackpot slots therefore tend to pay a lot more than offline ones.
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 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.
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.
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.
Brought to the industry by Big Time Gaming who were the very first to come up with the concept of Megaways. It was Bonanza Megaways that led to the mechanism’s major breakthrough as punters started realising that thousands of ways to win (instead of fixed paylines) was of course hard to resist. A big portion of modern slot games make use of the Megaways feature.
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.
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.
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.
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.
The very first land based slot machines were 3-reel based and this also holds for the very first online videoslots. As online 3 reels slots gave digital providers the chance to experiment with reels in all sorts of ways, they were able to come up with new features, mechanismes, and even more reels. Despite all the changes 3 reels slots have seen afterwards, it all began with 3 reels games.
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.
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.
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 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.
This explains why 5 reels slots were also released, which also included more features to make the games a bit more interactive and more fun to play. The main difference between 3 reels and 5 reels is that they come with new bonus features and themes. Some of the 5 reel slots have turned into all time classics.
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 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.
You’re more than welcome to join Enrico Mortis and his mariachi band, also known as The Boners, to celebrate El Día de los Muertos. If you accept Enrico’s invitation you’ll have a chance to win dropping symbols, explosivo wilds, and cascading reels with multipliers going up to 32x!
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.
Big Time Gaming has been highly successful in recent years and yet another reason for this is the integration of the bonus buy feature. This is also referred to as the feature buy or the buy a bonus, but the idea is pretty much the same: players are now given the opportunity to avoid spinning their way to the bonus feature, but can buy their way in. This costs some money, but saves a lot of time.
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 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.
Nolimit City’s Punk Rocker comes with an in-your-face punk attitude which is hated by some, but loved by many. The audio and graphics are a match made in… punk heaven.
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.
Talking about money: while visiting the best slots sites should clearly be about the fun, real money play can be a lot more thrilling as you’ll be able to earn yourself some money. And when there’s money in stake, things can get extra intense. This is why real money slots are widely available. They’re in fact a lot more popular than free demo games which you will understand. While playing online games is a lot of fun on its own, the thrill is always a lot higher when there’s a chance to win real money. There are thousands of real money slots games out there, with some of them being extremely lucrative. CasinoWebsites’ team of slots pros has listed the most lucrative slots, and based on our testing, we’ve come up with a mix of what we think are some of the best options when it comes to real money play.
For those that are looking for a safe and secure way to get into online casino gaming we would always recommend to play slots for free in the demo mode first. This mode is enabled by game developers to give players the option to test the games for free. At CasinoWebsites.com we always advise you to start with free play in order to get familiar with the game and the casino you’ve just signed up to. Only once you feel comfortable you can go ahead and decide to make a real money bet. Virtually all the casinos we list on our website work with demo modes, so make sure you make the most out of your experience by testing the slot game first. Eventually this may just turn out to be your next favourite real money slot.
