💪 Best Slots Sites With Other Casino Games
Before getting started with any kind of gambling, it’s important to have an overview. A slot site is a form of online casino or app which facilitates playing slots. Good slots sites offer a range of games for players to choose from, typically from various different developers.
Casino slot sites come in all shapes and sizes, some of which are more specialised, while others are broader in their appeal to players. An online slot site will generally offer a number of other games, such as blackjack and roulette, but slots are amongst their most popular attractions.
If you’re looking to get started at one of the best online slot sites, there are a number of easy steps to follow. Here’s a general overview of how the UK’s slots sites work:
As we mentioned above, there are a few steps you need to take to actually register with good slot sites. Let’s take a closer look:
The future is digital, and the best slot sites UK surpass their predecessors in many different ways.
The UK is a great place for those who enjoy a flutter! Not only is there a flourishing gaming industry which has a great variety of games on offer, but the UKGC is a robust and reliable regulatory body which does a great job of keeping players safe on gambling slots sites.
Because of the regulations which control every slots site UK players can rest assured that they’re not being taken for a ride. All you need to do is check that your site of choice is registered with and licensed by the UKCG before you sign up. This way, you can be sure that you’re going to get transparent terms and conditions and fair RTP (return to player) rates, which determine how much of your money comes back to you on average.
The UKGC also oversees certain data protection practices, so your personal details are safe and sound. Conversely, in many other countries, betting isn’t as carefully regulated, and players are at risk of being cheated or forced to comb through dense, murky terms and conditions or claiming a bonus only to find out that it’s subject to an unreasonable wager requirement.
Also, it’s worth mentioning that the range of game developers and suppliers who provide sites in the UK with their slots is varied, so you’ll have a great range of games to choose from. Simply put, the United Kingdom is home to some of the best rated slot sites in the world!
When we recommend slot machine sites, UK players can trust us. Our reputation is on the line, so our experts are careful to thoroughly vet every single site we recommend. In order to do this, they scour the latest slot sites with a number of important criteria in mind.
As we briefly touched on above, the best way to sort the good from the bad is to examine whether or not it has been licensed by the UKGC. UKGC regulations are strictly designed to protect players from harmful habits, unfair RTP rates, incomprehensible terms and conditions, and any site which would steal from its customers. When recommending a site to you, one of the first things our experts check is that it’s regulated and licensed.
The UKGC states that these sites need to have certain measures in place to protect consumers’ finances and identities. This generally entails encrypting personal details, ensuring secure fund storage, as well as implementing secure banking options to facilitate seamless money transfers and maintaining vigilant community moderation.
However, some sites do a better job of money and identity security than others, and we’re careful to only recommend those which are completely secure.
It’s vital that a top slot site offers its customers a choice of ways to pay. This is one of the main ways slots sites can differ from each other, so we always factor it in when making our assessments.
Basically, the more options, the better. Most sites support at least a few different methods, such as bank transfers, e-wallets and prepaid cards, whereas others accept methods like cryptocurrencies.
Enjoying popular slot sites isn’t about choosing a single machine and sticking to it. Variety is the spice of life! Whilst some sites offer a niche range, others offer a wide variety, and we think this is an important factor to consider when deciding which site is perfect for you.
Just as important as the variety of games is the variety of providers. Some specialise in IP-driven slots, whereas others create their own original titles. Some offer much better RTP rates than others, as well as better graphics and better mobile compatibility.
Promos are a big part of gaming, and they can make a huge difference to your bankroll when you register at a site. When making our recommendations to players, we always prioritise slot sites with free spins and deposit-matching promos.
Part of great service is great customer support, and this means offering players a range of different ways to get in contact in case they have an issue. It should be quick and easy to speak to a real person, and they should be reachable at reasonable hours, or ideally 24/7, which is not uncommon.
The meteoric rise of portable device gaming has provided players with numerous benefits:
It’s important to note the differences between apps and portable browser websites, as each comes with its own array of strengths and weaknesses.
| Characteristic | In-Browser Websites | Dedicated Apps |
|---|---|---|
| Interactivity/Gaming | In-browser sites can lag, lose your progress, or even log you out unexpectedly. | Apps tend to be more responsive, and the overall experience is smoother. |
| Regular Usage/Personalisation | In-browser sites aren’t great at remembering your preferences, and they don’t provide customisation. | Apps are best for those who use sites frequently, as personal details and preferences are stored on your phone. |
| Graphics and Effects | The graphics displayed in browsers are inferior to those provided by apps. | Apps are capable of delivering stunning graphics. |
| Native Functionality or Processing Required | In-browser options do much of the processing on remote servers, so your device isn’t doing the heavy lifting. | Apps function natively, requiring a device with suitable hardware to perform the necessary calculations. |
| Push Notifications | In-browser sites don’t offer push notification functions. | Apps can deliver notifications, letting you know when a new promo/game lands. |
| No Connection Required | In-browser sites won’t function without an internet connection. | Some apps can be used without an internet connection, which is great for travelling. |
Our experts know what players should be looking for when choosing between the top slots sites:
Bonuses are a big part of slots, and they come in all shapes and sizes. It’s possible to claim multiple offers if you’re savvy about it, but in order to do this, you first need to have a solid understanding of the main types you’re likely to encounter.
| Types of Bonuses | Description |
|---|---|
| Deposit Bonuses | This type of bonus is triggered by depositing money into your account and will generally reward you with additional funds or extra spins. |
| No-Deposit Bonuses | Slot sites no deposit promos are highly sought after, because there’s generally no financial risk involved at all. The most common type grants players with extra spins in the hope that they’ll pay some money in and become returning customers. They are also usually subject to wagering requirements. |
| First-Deposit Bonuses | These work only on your first transaction and may offer extra funds based on how much you deposit. For example, ‘pay £20 and get £40.’ |
| Welcome Bonuses | Bonuses like these are often highly valuable but can only be claimed once. Usually, they require a deposit first and are generally designed to draw new players to a new site. |
| Reload Bonuses | Reloads aim to generate customer loyalty, bringing players back with the promise of an extra promo. These are sometimes granted on a weekly or monthly basis. |
| Free Spins | If you’re a slot enjoyer, you will absolutely love a slot sites free spins! The spins themselves may not be worth a fortune, and they most commonly only work on a small selection of games, but they’re a chance to win real cash. |
| Loyalty Programmes | Like reloads, loyalty programmes seek to keep players coming back by introducing a points or ladder-based system which players can climb in order to win additional prizes. They may also involve cashback and other incentives. |
| VIP Programmes | VIP programmes are a way for the best slot sites to reward their favourite players and high rollers. They come in all shapes and sizes but often involve cashback. |
The newest slot sites out there generally bring new features and new promotions, but that doesn’t mean they’re necessarily the best! Here’s our overview for players of what’s good and bad about new slot sites 2023:
| Pros | Cons |
|---|---|
| New mobile slots sites run much better than their more dated counterparts | Not all new sites can be trusted, whereas established ones have a reputation to uphold |
| The newest sites often offer a larger range of games, recognising that variety is important to players | The longer a site has been active, the more reliable it is, whereas new sites can come and go quickly |
| Joining new sites sometimes means bigger bonuses, as they’re looking to draw in customers | Any software and banking glitches may not have been worked out if the site is still new |
| New slot sites adopt advanced security, including encryption, multi-factor authentication, and stringent identity verification | |
| The newer the site, the more likely it is to be hosting some of the newest games released by developers |
Whilst many UK players are drawn to older sites with established names, reputations and fanbases, overlooking the great new sites out there would be a massive mistake. As briefly mentioned in the table above, there are a number of advantages to choosing new slot sites UK. Both new and existing players should seriously consider these if they take their gaming seriously.
New sites offer innovative features, harnessing the latest technology for their banking and gameplay systems, benefiting players. Older sites can get left behind on a technological level.
Also, new styles of games are coming out all the time because developers all want to score the next big hit. These games are likely to land on newer sites first, as these are focused on innovation as a way of attracting players and building their customer base.
Generally, yes. However, it’s essential that you always check the reliability of a site before paying for it. The best way to do this is to either check that it has been licensed and audited by the UKGC or to simply select one of our recommendations, which our experts have already pre-checked for you.
There are a few key figures in the world of development. Each of the following developers/providers has their own approach to creating games, as well as their own dedicated fanbase. Let’s take a look at the companies you’re most likely to come across:
| Provider | Overview |
|---|---|
| NetEnt | NetEnt, also known as Net Entertainment, runs its own site whilst developing some of the industry’s most popular and successful games. NetEnt has been around since 1996 and has created such popular games as Starburst and IP (intellectual property) favourites like Aliens. Many of their games feature a progressive jackpot. |
| Playtech | Playtech slots have a grand aesthetic, with epic themes and a huge fanbase. They have been around for years and remain one of the most successful software developers out there. |
| Yggdrasil Gaming | Players love Yggdrasil games for their slot sites with bonus features and a variety of themes. Yggdrasil has only been going since 2013, but they’ve quickly grown into a highly successful and much-enjoyed developer. |
| Play’N Go | With their bright designs and flashy graphics, This company’s games are a feast for the senses. They also offer great payout rates and attractive jackpots. Their versatility attracts a wide range of players, both professionals and hobbyists. |
| IGT | IGT has roots in the brick-and-mortar world, having been established all the way back in 1951, but in recent years they’ve remained relevant and proven themselves to be a driving force in the world of slots, with great games like Cleopatra and Cluedo. |
| Novomatic | Novomatic is another company with a physical brick-and-mortar legacy, and it creates a wide range of games which extends beyond slots into card games and skill-based games. They remain on the cutting edge of high-end technology. |
Playing is great fun, but we all love to win! The best slot sites for winning UK are those which offer high RTP games. RTP stands for ‘Return to Player,’ and it’s a percentage rate which dictates how much of the player’s money will be returned on average.
Simply put, if a machine has an RTP of 95%, that means that for every £1 fed into the machine, it will return approximately £0.95 whilst retaining £0.05. This latter amount is the house edge, and these are the odds that players are hoping to beat.
Generally, anything over 96% is considered a reasonably high return rate, but the best payout slot sites may have RTPs of above 98%. The visibility of RTP may vary from one casino to another. However, it’s a good practice to make RTP available to players, so don’t forget to check them out. Be aware that the RTP can fluctuate based on the stake and that RTP rates don’t usually account for progressive jackpots, which can be highly valuable.
Players should also consider variance, which states how much the machine deviates from the RTP in reality. The higher the variance, the higher the risk (but also the reward). Without variance, there would be no chance to beat the system, which would make the experience rather dull!
Earlier, we touched on the importance of finding a site which offers a suitable selection of banking methods and how the best slots site offers a range of options for players to choose from. Each banking option has its own advantages and disadvantages, and the best option will vary from person to person.
| Type | Withdrawal Times | Examples | Advantages |
|---|---|---|---|
| Debit Cards | 3-5 business days | VISA, Maestro and Mastercard |
|
| e-Wallets | 1-2 days | PayPal, Skrill, NETELLER |
|
| Prepaid Cards | Not a withdrawal option | Paysafecard |
|
| Cryptocurrencies | Near instant | Bitcoin, Litecoin, Etherium |
|
The majority of slots sites have plenty more to offer than just slots, including a range of table games like roulette, blackjack, bingo and more. This, however, isn’t always the case.
We believe that, when choosing the right slots site for you, it’s worth factoring in the other offerings, even if you don’t intend to engage with them right away. Many sites out there offer a wide range of games from various different developers/providers.
It’s also worth noting that casinos with a wider range of games tend to offer a wider range of bonuses too. Some of these promos may span multiple games, offering a range of benefits to get new players involved. For sports fans, sportsbooks like Talksport Bet are slightly less common but still easy to find.
Generally speaking, variety is best. However, there’s something to be said for specialised sites which only offer slots, as the games which they have tend to be hand-picked. Also, the website and applications are typically more streamlined for slots players. Dedicated sites also often have a wider range of games and more specialised promos.
Choosing the top sites for real money slots is part of being a player! Demo sites with no real payouts are ideal for testing games or for those who are on a budget, but they do become a bit less fun after a while.
We closely monitor and keep tabs on sites which we recommend, and, in addition to considering their range of games, RTPs, volatilities, interface and more, we check if they are included in the list of the best slot sites for winning.
In conclusion, there are plenty of great slots sites for UK players to choose from, but the best option for one person may differ from the next. This is because each site comes with its own unique set of strengths and weaknesses.
Slots offer a fun and potentially fruitful way for players to enjoy themselves, but it’s important that you choose the right site in the first place – and this is where Slotozilla can help!
In the United Kingdom, all online slot sites are required to be licensed and approved by the UKGC, which is the organisation responsible for overseeing the industry and issuing licences. These licences show that a particular site is worthy of trust.
If a website is licensed and approved by the UKGC, then players can be confident that it’s not going to cheat them out of their money. The UKGC insists on transparent T&Cs, reasonable wagering requirements, and fair RTP rates. Only once these requirements are satisfied will they grant a licence which enables the site to trade legally.
The real answer to this varies depending on individual requirements, but some qualities worth considering include the variety of games on offer, the range of banking options, and the availability of other types of gaming on the same site.
Licensing is crucial for the reasons explained above, and it’s vital that players never pay money into - or even register for - an account at an unlicensed site, even if it looks professionally designed.
Yes! Fortunately, gaming on portable devices is easier than ever, and slots have been found to work particularly well on phones and tablets. Applications are great for frequent players, and modern ones run brilliantly on devices. In-browser versions of slots can be a bit unpredictable, but they will suffice for many.
Generally, as long as the site is licensed, it can be trusted. In the case of new sites, it’s even more important that trustworthiness is verified before any money or personal details are handed over.
The best slots sites UK players can access have great promotions, which are highly popular. These promotions boost players' bankrolls and help attract new customers to the site. When choosing the right site for you, always factor in promos!
First of all, when choosing the right site, players need to consider exactly what their personal requirements are. There are many factors to weigh up here, but our experts recommend thinking about banking methods, the variety of games and developers on offer, the interface of the website, portable playability, bonuses, and anything else that the individual might want!
