What Are Online Slots?

Consāidering the incredible creativity and sheer number of online slots out there, it is no surprise that many people arenāt too sure what classifies as an online slot.
Despite all the themes, all the graphical innovations, all the twists on the formula, we would say that slots – even online – have remained the same at their core. After all, the humble slot machine was a very simple game, and to this day, your bet is reliant on the outcome of the spin.
Now, what constitutes a successful spin does indeed change withź¦ each game, for instance, often the symbols you need to line up will be different. When playing online, there is also the addition of special bonus rounds, scatters, and wilds. Really, there arenāt many limits to what a bonus roundą¼ŗ could be, and that of course is part of the fun of discovering the distinctions between the many amazing titles out there.
Thereās plenty of room for creativity beyond mere aesthetics that the š best software developers have taken ample advantage of. However, there are some general constants that are common enough to be expected. Scatters, for instance, generally trigger bonus rounds, while wilds can usually fill in for other symbols when you are trying to line up your symbols.
In terms of distinctions, we would say that the bonus rounds, along with the looks and wagering limits šof the game, are where titles commonly distinguish themselves.
What remains consisteāntly true and can therefore define what slots are, is thus very simple.
Slots are a game where you win via theš“ result of a spin's effect on the reels and the symbolšs.
On a technical level, those wins are determined by a random number generator, in order to keep things fair aānd to give you a reasonable chance of winning. How slots sites wish to add to this is up to theļ·ŗm.
Fact Sheet:
-
Slots are the most popular casino game, hence š„their enormous scale.
-
Considešring this and that the UK alone spent Ā£14.2 billion between October 2017 and September 2018, that means slots count for an enormous chunk of change.
-
The first ošnline slot machine was created in 1994, šalong with the first online casino.
-
The win at the time of writing this best oš»nline slots review is believed to be worth ā¬19,430,723.60, which was from the Absolootlyš¼ Mad Mega Moolah game.
-
Slot games are replaced and created so often it is near impossible to get an accurate prediction of hšow many are out there at any given tiš¤”me, except to say there are many, many thousands.
How To Play Slots
Because there are so many different types of slots – not to mention the possibility of distinct individual bonus rounds or ideas – weāll have to speak generally when explaining how to play them.
So, with that in mind, hereās a general guide on how to play on slots sites that you can adapt to pretty much any title, āØwith a couple of additional notes to accošØunt for the many variables.
Log into your favourite bookmaker. If you havenāt found one suitable for slots yet, check out our list of recommended Best Online Casino Sites UK in 2022. Sidestep 1: If you need to download or updšate anything to play your favourite slots or utilise your favourite online slots sites on mobile, nšow would be the time to do it.
Deposit funds if you donāt yet have any in your account. Feel free to take a look at our recommended payment methods before doing so.
Read the rules: Each slot should have a guide telling you about its bonus features and what symbols and paāylines are available.
Choose the size of your bet: There will be an option to select how large a bet you want to place per spin. If the limits donāt suit you, choose another game. Keep in mind too that you can often use a feature called autobet, wherāe you select in advance how you wish to wager.
Select spin: When you are ready, all there is left to do is hit spin and hope luck is on your side. Sidestep 2: Utilise those bonus features: We canāt tell you what those bonus features are because they depend on the individual title, which is why we advise you to look at the rules. All we can say iš±s thāat scatters are usually your key to the bonus round.
Different Kinds of Slots
Whiāle there is a seešmingly endless selection of individual slots titles, they rather handily fit into a few different key categories, with a few subcategories to help further distinguish them. But really, you can fit almost all slots into three simple, easy-to-understand genres.
Classic
The classic slot is probably easiest to understand for newcomers because they are based on the land-based casino equivalent that has been around for generations. Generally speaking, youāll only have 3 reels (although five and even seven reels are possible) and a single payline on slots sites.All you need to do is match up the symbols to win.While they may be less generous in terms of payouts than some more modern examples, thereās no doubting the history, the aesthetic appeal, nor the simple joy of seeing three cherries line up and the ding-ding-ding of a big, coin avalanching win. There can be distinct design elements here, but many like to keep to the old favourites, and bonus jackpots can be available within its limited paylines – often for those betting the maximum stake.

Video
It may seem strange that our second category of slot game is called ‘video', considering that when it comes to online slots, they are all video, technically speaking. Most people do not know that the title actually makes reference to the history of this kind of slot.They initially appeared on land-based casinos and were distinguished by their video screens. These werenāt just aesthetic differences either, although they did allow for a huge number of themes and design motifs. Video slots also changed the game by offering a massive amount of new bonus features and ways to win.This was made possible because these slots werenāt held back by any kind of physical limitations. Today, the differences between classic and video slots might not be as immediately obvious when playing on slots sites. However, we would say that any one which steers away from the classic look, adds bonus features and extra paylines can be considered a video rather than a classic slotā.

Progressive
It seems like the progressive slot was the logical direction for video slots to go in as they began innovating in ways of making slots bigger and more exciting. Progressive slots are sometimes known as jackpots because that is exactly what they offer, sometimes in seven figures. That also alludes to the key distinction between video slots and progressives – the jackpot isnāt fixed, instead it āprogressesā with each bet. Many are even completely uncapped, meaning there is no theoretical limit and will continue until someone wins it. The way this works is actually quite varied. There are individual game jackpots where the total is based on that game. Firstly, there are network jackpots, where the bets of a whole system of games are all connected. Tiered jackpots allow people to win smaller prizes alongside big cash prizes for a more layered experience. Lastly, there are timed jackpots, where winnings are guaranteed at certain intšervals. Thereās also an enormous number of different themes, rounds and features, but ultimately what connects them is the progresāsive nature of the big payout.

How We Chose Our Best Online Slots Sites
Considering slots are the most popular casino game in the world, it should come as no surprise to learn that virtually every online casino you are ever likely to come across will include them, especially when looking at the best casinos in the UK, often as a major part of the operator.
In fact, weād say it is more likely to find a betting site which only offers slots and no other casino games than the other way round – with the exception of dedicated poker sites. Considering that, we had to be incredibly vigilant to makeź¦ sure we feel our list really does represent the cream of the crop.
How did we manage it?
Well, it in part comes down to how good the best online slots sites UK are generally. That means that all the things we usually do to determine the finest casinos out there are also in consideration here.
After all, it doesnāt matter all that much how great a game is if the minimum deposit išÆs too high to use, the site doesnāt load, there are no customer service options.
Quality is connected.
So, in order to even be considered for the best slots games, all candidates need to be at a high standard generally. Beyond that, we would say our consideration for the best slots casino specifically, mostly came downš§ø to the following five key factors.
Variety Of Slots
Weāve mentioned on several occasions that one of the cool things about online slots is that there are so very many of them. So many amazing developers, so much creativity, so much to choose from. In fact, we arenāt surprised at this point to see hundreds of slots available from one of the best online betting sites UK, and you better believe that when we are talking about the absolute best online slots sites UK and bź¦¬eyond, our appetite is ferocious for as many slots as we can get our hands on.
Quality Of The Games
However, one of the things that is so remarkable about online slot games is that despite there being such an abundance out there, the quality you can find across the universe of options remains consistently good to great – and we will certainly be expecting a majority of the latter for it to make our shortlist of the best of the best. We donāt just want a lot of slots – we want a lot of top-tier titles to make up that buffet of bets. Hey, we did say that the competition was fierce.
Easy Navigation
One of the issues though, with having an amazing and massive selection of titles is that it can be rather tough to make your way through them without some rather clever design going into the best online slots sites. This is not only where sound site structure comes into play but also where we get to examine how well the games are categorised, across different reels, slot types, themes (the popularity of slots means that themed slots have become a huge part of the industry) and even across software developers themselves. The latter is arguably the most effective and important point of categorisatišon because you can really get a feel of the difference between creators and get to know your favourites when properly organised.
Promotions
Another positive outcome related to the immense popularity of slots is that thereās an incredible amount of competition to be considered among the best online slots sites, all competing to grab your attention. This doesnāt just push operators to provide the best games they can, but also to sweeten the deal through slot promotions. Free spins, for instance, are one of the most common bonuses in online gaming, and we also see them commonly joined by welcome offers, free bets, free tournaments, random prize drops and more. Of course, the quality of promotions varies greatly. However, the best really can provide additional value to your betting experience. Best of all slots tend to countš° highly towards wagering requirements in comparison to š table games.
Mobile Adaption
All of this is made even harder on the small screen, and considering the immense amount of high-class titles we are looking for, you have to respect any of the best online slots which can live up to our standards on a mobile device or tablet. The best betting apps are naturally the gold standard here, although we do respect those which provide quality browser efforts, and put simply, we expect everything from the desktop perfectly shrunk onto the small screen with no impact on technical quality. In fact, in some amazing cases, the small screen experience can be even better thanks to increasedš interaction in the site and game design.
The Importance of Casino Variety
We realise that for many, slots are not their only consideration when choosing what casino is right for them. People like to have a variety of games, which is why the general quality of theā best online slots sites UK in our list was so important alongside slot speciš“fic considerations.
With that in mind, hereās a quick breakdown of five other kinds of casino games we took into account.
Lotto
The humble lottery has enthralled people for generations, and it remains one of the most popular types of betting today. The move online makes it possible to play lotto titles pretty much whenever you feel like, at least through the very best lotto options, rather than waiting for a weekly draw.
Poker
There is no card game which has captured the imagination of the gambling world more than poker. Itās appeared as a muse in films and books, songs have been written about it, paintings crafted, and we are sure the odd poem or two has featured a full house. Today, you can enjoy playing poker online with people from around the globe, utilising the finest poker sites whāiź§ch bring its imaginative brilliance to your screen.
Bingo
Two of the key facets which make bingo so great are its simplicity and the communal aspect. Both of those elements couldnāt be more perfect for a game to make the move to the online world. Itās a surprisingly deep game with plenty of variety but is still easy enough for newcomers to get involved. If youāre interested in trying it out or just seeing if another bingo site could be better for you, the list of best bingo sites is full of amazing options ź¦°and often ācontain great slot titles too.
Table Games
The same could also be said for table games as they are regularly seen side by side with slots. While they may be an afterthought for some lesser-known casinos, many offer truly spectacular table game experiences. Weāre talking blackjack, roulette, craps, scratchcards, baccarat, keno – if you could find them in the real thing, you can find them online too.
Live Casino
You may think that table games represent the closest experience to the real thing, but you would be mistaken – that honour must go to the best examples of live streaming gaming. What many of the best online slots sites have managed to achieve in this regard, especially when it comes to their mobile apps, still blows us away. Smooth streams offering play with life dealers can be an amazingly immersive experience, and if thatās what youāre into, this remainās the best optioš n for those not willing to make that trip to Vegas.
The Importance of Software Developers
Weāve madeš¹ it cleš²ar that the quality of slot games is absolutely vital to what we consider to be the best online slots sites, and there is no factor more important in that equation than the software developers themselves.
They are the creators of the games; the end result lies in their hands.
If you get really into slot games, youāll actually start to realise that software developers are probably the best way of distinguishing titles. We canāt say what your favourite software developer will be, but we can give you a shorš„tlist of some of our top contenders so you know where to start looking.
-
Microgaming: They were there during the olden times of the first online casino and they remain to this day a legend of the industry, continuing to create future classics.
-
NetEnt: Nipping at Microgamingās iconic heels is NetEnt, and you only have to look at the games weāve recommended to see that this developer is always in the running for best in the world.
-
Evolution Gaming: When it comes to the live casino, Evolutiš¼on Gaming are the absolute kingpins. This means tšhey might be lower on the list of traditional slots developers but their dominance in their field meant we to had to mention them here.
-
QuickSpin: As their name suggests QuickSpin, are a specialist in top tier video slots with š¼their own distinctive style, personality, and consistent quality.
-
WMS: Perhaps less known than some on this list, WMS are a large part of the reason branded slots are such a big deal now, breaking new ground with their beloveš d Monopoly slots franchises.
Playing Games for Fun
If you are on the hunt for the best online slots for you, itās important to note that you can do so without spending a penny on many of the best online slots sites. Yes, many will let you try them out for fun just so you can see how thešy work and š¦whether or not they are right for you.
This is not just a great way of demoing new titles, but in the case of complicated video or progressive slots, can also help you practise those distinctive bonus rounds and get to grips with any unusual rules you might not be used to.
This is also a great way of testing a game out on a technical level, seeing if everything works smoothly as it shouldš, and to ensure that no buffering is going to impact the enjoyment or success of your playā.
What Makes a Great Slot?
So, what exactly goes into making a great slot? Weāre not talking about basic functionality here, rather, what really makes one stand out? Here are six features to slot greatness we think all must follow.
-
They must look great and work seamlessly.
-
Video slots should have a unique selling point.
-
Classic slots must provide consistently excellentš¬ old-school game play.
-
Fair wagering limits must be in place to ensure as many people as possible cā±an enjoy that slotą½§.
-
The Return To Player rate (often known at the RTP rate) must be generous. This is a percentage which actually tells you how much players get back from their stake in the long run and is the most accurate way of objectively quanštifying the value of the game.
-
All games must be fair and secure. Nothing is more important to us than your safāety, so this is non-negotiable.
Security When Playing With Slots
We wanted to expand upon that final step not merely because of its importance, but because security related to online slots seems to be something that a lot of people donāt understand.
Security when playing on the best sports operators, for instance, comes down to the general security of the slots sites themselves. š¼Weāre talking about licensing, encryption, privacy policy, all that stuff that is so vital no matter how you like to bet.
However, because we are betting on games which are programmed by a third-party source, there is an additional concern and that is the security of the games themselves. The key here lies in the use of a random number generator, this ensures that winners are – as the name would suggest – random, and fair.
Often softwareš developers and occasionally the betting operators themselves will independently verify that the casino games are fair as well. And of course, there is the reputation of the software developers themselves, many of which have been provably fair for many šyears.
It is an additional security consideration, but if you use only the bš»est online slots with good software, especially išf you utilise our recommendations, then slots should not cause any extra safety concerns.
What Strategy Should I Employ When Playing Slots?
Want to know the best piece of strateļ·½gy foź§r playing slots?
Itās to practise responsible gaming.
When you are dealing with a game that is overwhelmingly based on random luck, ensuring that you stay in control is always the best policy. Making sure you wager responsibly, stay within your limits, and donāt chase losses means that whatever result lady šluck throws at you, youāre prepared.
To put this into a more concrete strategy, decide on a walk away point before you begin, and do not go past that amount.
That said, although slots might not have the strategic depth of something like poker, and though they may not require the research of good sports betting strategy, there šare some tips which can help make the most out of your gamāe. Here are a few:
-
Kšnow how much you need to stake to be eligible for the jackpot if thatās what youāre going for.
-
On progressive slots, consider focusing on the smallerź¦ jackpots for a better chance of winning.
-
Start small when getting to knoš“w the game, or even practise with no cšash where possible.
-
Read the rules thoroughly before starting.
-
Go for games with a high RTP rate.
