How we select the Top 10 casino slot games

Online slots have a host of features – some exciting, and others less so. Use these pointers to check what features are a ‘must-have’ if you want to play the best online slots UK players could ever need.

Make sure you play slots online worth playing. Discover the 10 most important factors when selecting the top casino slot games in 2020.

1. Free Play and Real Money Play

If you’re like most of us, you’re going to end up playing your casino slot games for real money. While free play has its moments, there’s a lack of prize money and rewards when your spinning demo slots. That said, free play allows you to test an online slot before you even deposit. That’s why you’ll find hundreds of free games in our best online casino reviews UK line-up.

We give weight to new slots that come with practice play and free demos; it shows that both the casino and developer have confidence in their products/games. Importance Percentage 70%

2. Gameplay

The best UK slots online keep us coming back. We call it gameplay, and it’s what makes the difference between entertaining games and boring ones. How the slot plays is very important. This is where the developer brings together graphics, RTP, features and paytable – a combination of elements, code and mathematics that makes the magic happen; or not happen.

Gameplay is the way players interact with online slots, how the game is played, the rules and any features. The best casino slot games in the UK will offer players more than just bet and spin. Excellent gameplay is about what comes next.James Slotsquad

Online casino slot games in 2020 offer some of the best interaction between player and paytable. It’s not just about spinning the reels and lining up three of the same symbol. That’s why we focus a lot of our attention on gameplay. The better the gameplay, then the better the features, paytable, RTP and graphics – the overall experience and potential rewards will likely be better too. Importance Percentage 90%

3. Developer

Once upon a time, slots online resembled arcade fruit machines, bandits and very basic slot machine games. But today’s best online slots are rewriting the rules with improved design, code and gameplay. If you want to build excellent slot games, you need good developers, development tools and experience. That’s why some slots developers are better than others. In 2020, we see the top UK slots come from big companies or smaller firms backed by larger investors.

Our list of the top 10 online slots for UK players to play is updated regularly. This list includes games from some of the best developers in the world – it’s important to play slots created by reputable developers. We want legit slots, licensed games and fair play on the reels, not rigged slots from unknown sources. We created this list, so you know which casino slot games you can trust. Importance Percentage 68%

4. RTP

RTP, return-to-player is a payout percentage and the odds of winning a prize when playing online slots, FOBTs, fruit machines or other electronic gaming systems that involve waging real money. RTP is an average achieved over a significant number of game plays and not each time the gaming machine is played. That’s why you shouldn’t look squarely for the highest RTP slot games.

The best RTP slots are the highest RTP slots, or so you might think. iTech Labs is just one of the world’s independent testing agencies when it comes to audits of game outcomes. If an online casino tells you that this game is 96.5% RTP, they check. If a developer promises 98.2% RTP on this particular slot, they verify the maths.

While we do look at casino slots with high RTP numbers, we don’t pay too much attention to the value. High isn’t always better. For instance, a high volatility slot with a low RTP might be more exciting than a low volatility game with a higher RTP.

But can we trust RTP? Thankfully, as of 1 September 2016, the UK Gambling Commission requires that all remote operators (online casinos) with a UK license must monitor the performance of the games they offer. Even though games must be tested before use, over time, they might be underpaying or even overpaying players. RTP is important, but don’t always look for the highest RTP slots. Importance Percentage 59%

5. Max Bet vs Min Bet Slots

Low bet slots, max bet slots – if you’re playing for real money, betting limits come into play. But why do we look at bets when ranking the top 10 online slots in the UK? We’ll talk about the paytable, free spins bonus and features later, it’s all linked to betting; however, we’ll talk about betting limits at this point.

Max bet vs min bet slots is very much down to player preference, but the best casino slot games offer the biggest range between the two. For example, an online slot with a min bet of £1.00 and a max bet of £50 is less appealing than a min bet of £0.10 to a max bet of £500. Min bet slots are better for responsible gaming; max bet slots might attract high rollers and less conservative players.

High volatility slots with a minimum bet make some of the best slot games you can find, low volatility games with a higher minimum bet can cost players the earth to trigger even the smallest win. When we rank our top slots, we’re looking for online slots with the lots of features, but also a low min bet so that players can take their chances with less of the betting cost. Importance Percentage 83%

6. Slot Paylines

Paylines on slot machines can start from 10 and go up to many thousands; they’re also advertised as ways to win. Our best online slots UK list includes a variety of games with both high and low numbers of paylines. But remember, a slot game with 99 paylines doesn’t necessarily mean winning more prizes than you would on a game with 25 paylines.

The slot’s volatility, features and the amount given to symbols on the paytable are more important than paylines. Importance Percentage 62%

7. Pay Table

If you want to understand slot machine pay tables, it’s basically the rules of the game. Often consisting of high paying symbols, mid-paying symbols and low paying symbols, a pay table along with RTP and pay lines is the mathematical stomach of any casino slot game.

Line up three cherry symbols; it’s the pay table that awards the prize, trigger the bonus game, again you can thank the slots pay table. Pay tables will often contain bonus features, multipliers and free spins games as well.

Pay tables are the most important piece of any online slot game, especially if your playing for real money. Not volatility, not RTP, and not betting limits – as it’s the pay table that directs how much you can win!James Slotsquad

New UK online slots in 2020 feature complex and significant pay tables, the key is finding games with more rewarding pay tables. We can now talk about the betting limit, paylines, RTP and volatility once again. To find the best slot games, we rank our list based on strong pay tables. At first, we want a good number of symbols. Second, we look at the value of those symbols. Finally, we look at the RTP, volatility, min bet and max bet.

Regardless of volatility or RTP, it’s the slots pay table and what’s on it that controls the amount of wins. RTP and volatility direct when you might win, but it’s the pay table that says how much. That’s why list our best slot games based on the pay table first, and the other factors second. A pay table is the most important thing to look at if you want to play slots online for real money. Importance Percentage 94%

8. Bonuses, Free Spins and Features

From free spins to multi-level pick and win games, the best bonus feature slots are getting an upgrade in 2020. Now more than ever before, we’re looking at the best slot bonus features when we rank online slots. Other than standard pay line wins, features are any additional part of the game that can help generate wins.

If you play slots online, online slots with bonus features are the way to go. They offer the best prizes, entertainment and gameplay. When you’re looking for your next casino slot game, consider one with lots of in-play features and extras – it changes the game completely.

You’ll find loads of games with features in our top 10 UK slots to play in 2020, including:

• Gamble Feature Slots
• Free Spins
• Different game modes (see image above)
• Multipliers
• Stacked Symbols
• Super Symbols
• Tumbling Reels
• Megaways™
• Pick and Win
• Random Games
• Wild
• Expanding Wild
• Walking Wild
• Nudges
• Multiple Jackpots
• Expanding Reels
• Wild Reels

Importance Percentage 90%

9. Quality and Speed

When it comes to graphics and quality, resolution and frame rate are the key factors that online slots developers struggle to balance. How does the online slot look? How does it spin? Is the animation any good? How blown away are you by the visuals. With new online slots, we see smoother and more immersive graphics on screen, that’s precisely what we want. The problem with casino slot games is repetition, watching the reels spin over and over.

If you look at our best Grosvenor slots list, you’ll find some of the highest resolution games on the planet. On the other hand, our best 888 slots list focuses on frame rate. How a game looks and how a game moves are two very different things, but done well together, it can really entertain. That’s what makes our best online slots UK rankings – casino games with both a high resolution and a high frame rate. Importance Percentage 85%

10. New Casino Offers

Finally, any new casino offers related to new online slots is a good indication of quality. Whether it’s free spins, game of the month or a deposit bonus – new games won’t get the full promo treatment if the product is sub-standard. Promotions and bonuses tell us that the casino and developer have confidence in their latest release – and that it’s likely one of their best online slots UK players might find entertaining. Importance Percentage 70%

Ranking the online slots available for British players turned out to be a surprisingly difficult task. We had to not only consider the quality and the features of the hundreds upon hundreds of fruit machines out there but also whether or not they are offered by reputable UK-licensed sites which have juicy bonus offers. But after months of research, we managed to discover which are the best slot sites and which are the top slots you can play there. Continue reading to discover what to look for in an online slot destination or simply click on the secure link button that will take you to the casino!

Before we go into detail into what makes these particular games the best, we want to make sure you know that all the slots we recommend can be found at websites that are licensed by the United Kingdom Gambling Commission: the only regulatory body that can authorise online casinos to offer their services on the UK market. This means that no matter which of the casinos we recommend you choose, you will always be guaranteed a fair gaming experience and 100% safety of your personal information and money.

Online Slots Best Bonus

There are of course many exciting slots other than the ones in our ranking, but most of them are not offered by top UK slot sites or are offered by casinos that don’t have many bonus opportunities. After all, even though having a great bonus to play with doesn’t speak directly about the quality of the slot game, it greatly enhances the experience of playing on the Internet and gives you better chances of ending up with a gain. Check out the top welcome packages that you can claim online as a UK player in the table below. If you’re interested in a particular offer you can also check out our in-depth reviews of the best online slot sites for more details.

Best Free Spins

Some casinos prefer to offer welcome bonuses that consist solely of free spins. Such operators are perfect for slot lovers, as this bonus cannot be used on any other type of casino game. Most free spins offers include a bonus sum alongside the spins, so you can also take advantage of playing other games at the casino, apart from slots. Such kind of offers are preferable as they give you freedom, but if slots are your heart’s desire and you have no interest in other games, then you would be just fine with a free spins offer. In the following paragraphs, we will explain what exactly free spins are and how you can win from them. So, keep reading!

We know how hard it is for players to choose between the many casinos available online and we would therefore like to offer our help. In the table down below, we have given you a list of the best casinos with free spins available on the UK market:

What are free spins?

A free spin is every spin of the reel on a slot game for which you must not pay. If a part of your bonus consists of 200 free spins, that would mean that you can spin the reel 200 times without paying anything and all that you win would go to your bankroll.

Can you win from free spins?

Yes, you can absolutely win from free spins. One way to do so is to claim a welcome bonus, which includes free spins and then use them on slot games at the casino. Another way to win money from free spins is to win a bonus round of spins while playing a slot game. Both methods work best if you have some sort of a strategy for playing.

Slot Casinos with Real Money

If you have practiced on demo slots enough and you now wish to play for real money, you are definitely going to need to consider a few important factors before choosing a casino. Firstly, you need to always look for a secure and safe operator. You can make sure a casino is safe when you find that it has the needed licenses and certificates to function legally in your country. For the UK, such certificates include the UK Gambling Commission and the Malta Gambling Authority. Other important factors to consider are the game catalogue – does the casino offer various games from several software providers?

Furthermore, the welcome bonus is always a great advantage of an operator. But you must check the bonus and conditions of every offer beforehand. The main conditions to look for are the validity period, the wagering requirements, the accepted payment methods, etc. But to make it easier for our readers, we have handpicked the very best online operators. Here, you can discover the top casinos with real money slots on the UK market:

Can you play slots online for real money?

Yes, you can. There are numerous reputable online casinos, which offer a great selection of slot games you can play for real money. If you are a newbie and you are just starting to play slots for real money look for games, where you can bet small amounts.

Can you really win money on slot apps?

There are many gamblers, who win extra cash from playing slots on their mobiles. But if you are unsure and want to test this fact, you can always choose an app, which has a free spins bonus and take a test run on a game to see what happens.

The Best New Online Slots

We have something little for every type of gambler on our website, especially for the experienced. If you are a “professional” slot player with hundreds of titles behind your back, you will probably not be too captured by the most popular slot games in the industry. What you are looking for are the newest and hottest top slots that have entered the market. With a little bit of research, we have managed to find the newest and best slots, which will become a total hit in 2019. Here, you can find the best new slots for 2019, which their provider is and what the payout and variance rates are.

New Slots 2018

If you have been on the search for the top new slots for 2018, you should look no further. In the next table we have presented the best slot games, which were released in 2018. We will rank them according to their payout rate and number of paylines and would also provide info on who the software developer is, the exact release date and which safe online casino offers the game in its catalogue. One such game is Double Stacks. It was released on 24.9.2018 by Netent and has a payout rate of 96.1%. The theme of this slot includes fruits, sevens and bars, which produce wins of up to 1,000x the stake on a single spin. What’s not to love! One tiny disadvantage of this slot is the scarce number of paylines – just 10.

Another game, which also hit the online casinos in 2018 was Age of the Gods: Mighty Midas. The slot was released on 21.12.2018 by Playtech and has a payout rate of 96.34%. Playtech has a history of boasting progressive jackpot slots based on Marvel superheroes and they continue their legacy. With a majestic and royal theme and numerous bonus features, this slot has quickly become the newest player-favourite.

Best Payout Online Slots UK

Every online slot machine has rules that are set in such way that in the long run the casino has a slight advantage. Most fruit machines return between 94% and 97% of the money that’s wagered on them in the long run. This percentage is called return-to-player percentage (RTP) and is one of the most important ranking factors for online slots. The higher the RTP, the better are the chances for the players. Check out below how the top online slots compare when it comes to this aspect of the game.

Big Bad Wolf – 97.29%

Big Bad Wolf is inspired by the tale of the Three Little Pigs chased by a wolf, trying to blow their houses down. The reels are framed within a large straw house, with running hills. The payout rate of this game is quite high compared to other competitor slots.

Immortal Romance – 96.86%

Powered by Microgaming, Immortal Romance is an efficient looking slot with a gothic atmosphere and a thrilling vampire theme. The game is all about forbidden love, where some characters are madly in love with each another, but they can’t be together.

Fruit Stack – 96.28%

Fruit Stack is one of the best non-progressive jackpots in the industry today, coming in the form of 10,000x times your initial bet. You get this when you manage to land five of the diamond wild symbols on any active payline. This is why its payout rate is also quite high.

Starburst – 96.1%

Starburst is one of the most popular slot games ever and is developed by Netent. All Starburst slots feature 5-reels with a total of 10-paylines that could reward you with an amazing 50,000 coins regardless of whether you’re playing online or on your mobile device.

Buffalo Blitz – 95.96%

Embark on a journey that will take you far away to the lands of Africa and the jungles of South America. This is a fantastic and beloved slot game, produced by Playtech. The wildlife theme of the game will allow you to meet numerous fantastic wild creatures, while you win some extra cash.

Ted – 95.805%

Based on the 2012 comedy, Ted is a BluePrint video slot game, which follows the adventures of the famous talking teddy bear, and allows you to enjoy all of his highly inappropriate comments spin after spin.

Cleopatra – 95.2%

The game is based on the enchanting Egyptian Queen, Cleopatra, and it incorporates many of the Egyptian culture in its theme. Apart from the mesmerizing theme, this slot also has great bonus features and winning opportunities.

Best Online Slots Uk 2020 Online

Rainbow Riches – 95%

Barcrest’s Rainbow Riches has become one of the most popular slot machines in the recent times. The video slot comes with five reels, 10 paylines and 18 paylines. The game is available at a large number of online casinos, due to its increasing popularity.

Halloween Fortune 2 – 94.99%

Halloween Fortune II is a beautifully designed slot game with 5 reels and 25 paylines, featuring three spell-binding witch characters and a whole load of intoxicating potion symbols. It also includes numerous bonus rounds and free spins for a greater chance of winning extra cash.

Top Cat – 92.48%

Top Cat by Blueprint Gaming is inspired by the famous 1960s Hanna-Barbera cartoon. Like most franchise-based slot games, Top Cat aims at reproducing the settings of the original product faithfully. Its payout rate is not as high as we would have hoped for but is still acceptable.

The Best Online Slot Softwares

As you probably have noticed from the table above, most of the online slots in our ranking are developed by the three major software houses in the field of online gambling: NetEnt, Playtech and Microgaming. Though that’s not always the case, here bigger equals better: these providers have such a history and experience in the development of online casino games that there are almost no minor companies that can compete with their standards. Probably the only smaller software house that can find a rightful place near these giants is Random Logic, the developer of many of 888’s games, including Millionaire Genie. Read more about these top slot providers below:

Netent’s Slot Selection

Often you can tell that an online slot is developed by NetEnt by just looking at it. The superior graphics and the exciting themes are usually more than telling. On top of that, the software behind the games is 100% fair, which is tested and verified by reputable gambling authorities and independent testing agencies such as The United Kingdom Gambling Commission, The Alderney Gambling Control Commission, The Malta Gaming Authority, The Gibraltar Gambling Authority, The Global Gambling Guidance Group (G4), eCOGRA and iTech Labs. Some of the best NetEnt slots that you can play online are Gonzo’s Quest, Jack Hammer and Jack and the Beanstalk, which is arguably the most exciting and best-looking online slot that you can play online.

Playtech Casinos – The Home of Great Slots

Playtech is the most popular casino software provider. They are a very reputable company with over 15 years of experience in the development of online casino games. As they are licensed by the UK Gambling Commission and traded on the London Stock Exchange, you can be sure that all their games are fair and the outcomes of the hands/spins are truly random. Some popular Playtech slots that you will surely enjoy trying are Monty Python’s Spamalot, Gladiator, Kong, Little Britain, Sopranos and The Three Musketeers.

Microgaming – The Original Casino Software

Microgaming is a true giant in the world of online gambling. The company was founded in 1994 when it launched the first ever online casino and since then has won numerous prestigious awards for their work in the online gaming sector, such as eGaming Review Magazine‘s Award for Innovation in RNG, Innovation in Slot Provision and The Gambling Online Magazine Award Best Casino Software. Most of their games, I would have to admit, don’t have the same high-quality graphics as the ones of NetEnt, but their newest titles such as Game of Thrones and Jurassic Park have really elevated the standards of how a casino game should look. Other great slots that you can find in Microgaming’s portfolio are Immortal Romance, Terminator II, Battlestar Galactica, Avalon II, Thunderstruck II and the most popular online slot in the UK – Mega Moolah.

Random Logic – 888’s Proprietary Software

Random Logic is a company that’s part of the 888 Group and as such it develops games for the best online casino in the UK – 888. The games they have developed are of equally high quality in both instant-play and download mode. On top of that most of them have really smooth and well-functioning mobile versions. But the most exciting and appealing feature of their game selection without a shadow of a doubt is the uniqueness. Some of the top slot titles offered by Random Logic are Ultimate Universe, Snack Time, Viva l’Italia and the top-ranker in our online slots ranking – Millionaire Genie. In their portfolio you can also find some exciting progressive jackpot slots like Ultimate Grill Thrills and Pirates Millions, the latter of which offers one of the highest jackpots you can find on the Internet – £8,888,888!

There are of course many other software providers that offer great casino games and that definitely deserve your attention. Among those are IGT, Cryptologic, Greentube and Blueprint Gaming, to mention but a few.

Mobile Versions of the Games

As today more and more players choose to enjoy their favourite games directly on their mobile phone or tablet, a very important aspect of any online slot is whether of not it has a mobile version. Actually, we were kind of pleasantly surprise to find out that only 6 out of our top slots don’t have a mobile version and those were Genie Jackpots, Monopoly, King Kong, Reel King, Wheel of Fortune and Wizard of Oz. On the other hand, we were very impressed by the look and feel of the mobile versions of Millionaire Genie, Starburst and Twin Spin. These mobile slots are so good and so close to the original ones, that we literally forgot we were playing on mobile.

Sure enough there is a lot more to know about how you can play on the go like for example with which devices are the games compatible, are there available apps for iOS and Android, what type of apps are there – downloadable or web-based, and so on. You can learn more about all these topics and more on our dedicated mobile slots page.

Fairness and Security when Playing Online

When computerised games were first introduced to the public, there was a great deal of mistrust regarding this new technology. Many people were suspicious that the games could be rigged in the casino’s favour. Whilst this is an understandable fear given that the inner workings of the games cannot be seen, all online casino operators who serve UK players have to be regulated by the UK Gambling Commission before a gambling licence is awarded. The Gambling Commission monitors closely the activities of all operators who serve UK customers and has been set up to safeguard the player’s interests. The casino companies themselves have also taken big strides in becoming more transparent and many of the online casino companies are also subject to third-party independent testing agencies who scrutinise the game results to ensure that the outcome of the games are truly random. The best examples for such companies are Gaming Laboratories International (GLI), iTech Labs and eCOGRA. You can learn more about them by clicking on the logos below.

Random Number Generator (RNG) – At the heart of every game at an online casino including slots, roulette, blackjack and poker, is the random number generator (except live casino games). The RNG is the mechanism that decides the result of every game. When you press ‘spin’ or the ‘start’ button, in reality the result has already been decided and the spinning effect is really just for the show! The ending position of each reel is independently decided by the RNG for each reel.

As each spin is random it is worth remembering that it makes no difference whether you have played one spin or one thousand spins, the odds of getting a win will not change. However playing more win-lines does increase the chances of winning but as stated before this does cost more so having control of your bankroll is an important part of playing.

Is it legal to play online slots?

The answer to that question is yes. Online gambling is legal in the UK, provided the casino you play at has all the necessary certificates to function. The administrative authority, which decides what casinos are safe for players is called the UK Gambling Commission.

Are online slots rigged?

As long as the casino you play at is reputable and has all the necessary certificates, you can be sure that the slots from its catalogue are not rigged. There are testing houses, which check for the fairness and RNG component of the games and thus ensure gamblers’ safety.

As we already mentioned, testing and ranking all the slots available for the UK was no easy endeavour. Even after we filtered out the ones that aren’t offered by UK-licensed sites, we were left with a pool of over 500 fruit machines to choose from. You can find way more online slots free to play at slots.info. In order to significantly lower this number we did a little marketing research to find out which are the most searched for slots. After all, usually there’s a reason behind the popularity of a certain game and often that reason is that the players are more than happy with the experience of playing it.

So this is how we managed to narrow down the available games to 24 and from there on we prepared a list of criteria according to which to rate them. Of course, there might be a more appropriate slot machine for you than the one that we ranked number one. There are many options and features that set apart one slot machine from another. For some players having the highest possible odds for a win, i.e. the highest theoretical return-to-player percentage, might be the most important thing, while for others having great quality and many bonus features is way more exciting. No matter what your priorities are though, I’m sure you’ll find a lot of useful information in the next paragraphs.

Gaming Options and Features

Even though the goal when playing fruit machines is always the same – getting a winning combination of slot symbols on the reels, every game features different options and winning opportunities. Most online slots offer free spins that are usually won by getting three scatter symbols on the reels. Other games have expanding wilds, stacked wilds, multipliers, respins or feature a gamble option. They also feature different number of winning lines and a different bet range. Some of them even offer life-changing progressive jackpots. In the table below we’ve collected basic information about the features of the games in our ranking.

Another feature that can make your experience even better is the autoplay option which is especially useful when you’re wagering a bonus. Usually, this option can be set to stop whenever a feature is won so that you don’t miss any part of the fun. You can further cut the suspense of waiting for the exciting bonus rounds and the profitable free spins if you turn on the ‘quick spin’ option that some online slots offer. Not to mention that this way you’ll satisfy the wagering requirements of your bonus even faster.

The Theme of the Slot – Graphics, Sounds and Animation

One of the first things that tempts players to try a new online slot is the theme and the design of the game. The creators of video slots draw inspiration from various subjects such as famous TV shows, movies, computer games and comic books. Other games are merely revamped versions of classic fruit machines that are famous in land-based casinos. Whichever the case, most players enjoy slots with superior graphics, animation and audio. Take a look at the scores we gave each of the games in our list in these three categories in the table below:
