New Slot Sites

Like many things in life, not everyone is loyal to just one brand. In fact, many players like to mix it up when playing their favourite online slots, switching from slot site to slot site often. 

This might be down to the fact that one slot site has a different set of games to another, or because they want to take advantage of a new and lucrative welcome offer or bonuses on offer… Or maybe just because they feel like trying something new and different to what they’re used to.

Something new is exactly what you’ll find right here. All of the new slot sites you’ll find in this section have been carefully vetted by our expert team to ensure that they’re filled with online slot games from the best developers. We promise you won’t be disappointed with this selection of impressive new slot sites.

Slot sites: How they work and which are the best

Ready to sink your teeth into some of the very best online slots? Perhaps one of the most important decisions you can make before playing for real is which slot site to play at. There are literally thousands of slot sites to choose from, each with their own pros and cons, and most offering something a little different from the next.

Most of the best slot sites out there are firmly committed to delivering players the latest and greatest titles from the best slot developers in the iGaming world. Some will focus on slots that boast the biggest and most breathtaking jackpots. And others might focus on targeting new players with irresistible bonuses and free spins.

Rest assured that we here at Slot Gods take immense pride in being honest, bias-free, and trustworthy, not only in our online slot reviews, but also in our slot site reviews. We only partner with the best slot sites in the business, all of which we have personally tried, tested and spent countless hours playing at with our own money.

Rather than just take our word for it though, it's useful to understand how slot sites work, the various differences between them, and of course, what separates a good slot site from a poor slot site, so you can be confident that whichever one you choose to play at will offer all the features and games you enjoy, and importantly, is safe and secure...

What is a slot site?

Slot sites are incredibly complex and there are many critical functions they must perform in order to operate. To understand what makes a good slot site, it's useful to know what these functions are, the options available, how players make use of them and how players benefit from them.

Platform & Software

Contrary to popular belief, slots and casino games aren't actually hosted by slot sites and online casinos. They are embedded into the website but served from 3rd party servers - usually the game developer's own server, or a third party intermediary. This ensures that the developer retains control over the games, can apply updates, fixes and improvements in real time. It also ensures that games can't be tampered with or 'fixed'. Most games also require a central database to store information such as jackpot contributions, points, wagers and wins.

With so many tens of thousands of games available, it would be virtually impossible to integrate each game individually, and so some sort of intermediary aggregator software is almost always necessary. The slot site can integrate this software into their website and leave to it the responsibility of serving existing games, releasing new online slots, and applying necessary updates and improvements.

Historically, game developers themselves have provided this software and over the years have evolved to integrate third party developer games into it, meaning the slot site has only one integration to be concerned with, while still being able to offer players a choice of games from a variety of providers. Nowadays, independent game aggregators exist providing an even wider choice of games, and some slot sites implement multiple integrations for maximum reach to virtually every game available.


A slot site wouldn't be very successful if it couldn't take deposits and make withdrawals. However, there's more to slot site banking than processing payments. Due to regulations, including anti-money laundering (AML) laws, online casinos and slot sites must pass a number of audits and assessments to ensure the funds they take from players are being processed safely and securely and are held in a 'client account' protecting them in the case of a slot site becoming insolvent so funds can be returned to players. No sensitive payment information can be collected or stored unless certified to do so, and in recent years, affordability checks must be performed to ensure funds have been sourced legitimately, can be justified and be deemed affordable.

Furthermore, players have their own preferences as to which deposit methods they use. Some prefer using e-wallets such as PayPal or Skrill, whereas others prefer to use their Visa or Mastercard debit card. In the UK, the use of credit cards for online gambling is now banned, so for most slot sites, e-wallets, debit cards and bank transfer are the only options available, although some do also accept 'pay by phone' methods and even cheques!


All gambling operators serving UK customers must be licensed by the Gambling Commission. There are various licenses available, some based on turnover, others based on product e.g. sports betting, bingo, and lottery, as well as online slots and casino games. All license applications involve thorough background and suitability checks, audits and analysis, and cost well into the thousands of pounds. Operators must also adhere to license conditions and codes of practice which are regularly monitored and updated by the Gambling Commission to ensure they are acting responsibly, safely and treating players fairly.

The strict licensing conditions are a huge barrier to many new operators wanting to enter the UK market, and as conditions have become more stringent over time, some have either surrendered their licenses or ceased trading entirely.

Customer Service

Whether a customer has a question or a problem, good customer service is imperative to any business operating online. The more caring and helpful the customer service, the more content and loyal customers tend to be. Furthermore, most issues can be amicably resolved without having to refer to lawyers and ombudsmen, with a simple phone call, email or online chat.

Employing customer service agents has its own complications though - not only in terms of training, but also in terms of supervision, handling of sensitive data, and further still, the fact that slot sites generally operate 24 hours a day, 7 days a week, and 365 days of the year! Having enough qualified people on stand-by round the clock can be troublesome and costly, but the best slot sites understand that the welfare of their customers is paramount.


As mentioned earlier, the selection of games a slot site has is often determined by the platform and aggregator software they have implemented. The greater the selection of games a slot site has, the more integrations will be necessary, and so the higher the costs and fees involved. Some slot sites prefer to keep operations slim, offering a modest selection of games ensuring they cover the most popular and better known titles. This approach, however, has its limitations, especially in recent months where lesser-known developers are releasing outstanding slots that players can't wait to get their hands on. If the slot site doesn't integrate an aggregator that includes a certain developer's games, then new and existing games from that developer won't be available to players, which can lead to disappointment and lost custom.

Other slot sites really do go all-out, ensuring they not only have virtually every online slot available, but are also among the first, or even only ones, to be able to offer blockbusting new titles to their players - Videoslots, Casumo and EnergyCasino deserve a mention here, as we've become to rely on them the most for almost always having the best new slots as soon as they launch.


Some players are all about the mega big wins - and who can blame them? Slot sites know this, and some focus heavily on ensuring they boast a broad selection of jackpot slots including networked and progressive jackpots which are renowned for reaching well into the millions. Additionally, daily and hourly jackpots, such as the Red Tiger Daily Jackpot, have grown massively in popularity in recent months, and have become a key selling point especially for mainstream slot sites.

Not all slot sites have a large choice of jackpot slots though, even if they excel in other areas. Again, it usually boils down to the platform the slot site is built on to decide what jackpots are available. On the other hand, many players tend to avoid playing jackpot slots as typically they have a lower RTP, so much of the decision on whether to focus on them or not comes down to the slot site's strategy - is their objective to attract fans of jackpots, or have the best slot with the highest RTP?

Welcome Offers & Bonuses

Literally every slot site out there will have some kind of welcome offer or bonus available to new players to incentivise them into signing up.  Welcome bonuses play a huge role in how slot sites attract new customers and come in a variety of formats including deposit bonuses, no-deposit bonuses, free spins, and cashback.

Bonuses are generally tailored to the type of player the slot site is trying to attract. Slots players tend to go for free spins, whereas traditional casino game players tend to go for deposit bonuses.  Each have their pros and cons, and bigger doesn't always mean better in the world of bonuses, as slot sites must attach terms and conditions to their offers to protect their profits, and generally, the more 'generous' the bonus the harsher and more restrictive the conditions will be.


Promotions are as important to existing players as welcome offers are to new players. They keep players engaged and returning to the site. They also reward loyalty, and often form part of a celebrity endorsement or TV programme sponsorship. Promotions include anything from ad-hoc free spins to try out a new game, to seasonal promotions such as advent calendars and easter egg hunts, to weekly slot tournaments and leaderboards. Prizes include free spins, deposit bonuses, free cash, holidays, and physical gifts such as electrical products and even cars!

Promotions are popular amongst players providing they are well thought out, are simple to follow, easy to enter, and the prizes are worthwhile. Some slot sites focus heavily on promotions to re-engage their customers, whereas others don't really seem to care much about them, perhaps making up for it elsewhere.

What makes a good slot site?

Now that we've broadly explained what a slot site is, how do we tell the difference between a good slot site, and a poor slot site? Well, that depends on the demands and needs of the player. Players wanting to deposit using a specific payment method won't much enjoy a slot site that doesn't support it. On the other hand, players who only want to play jackpot slots might be more flexible over which payment methods are accepted.

Then there's the overall design and usability of the slot site to consider - is it easy to navigate and find the games we want to play? Can the site be used with ease on mobile devices, and are the games mobile compatible (most are these days).

The core factors of a good slot site include a respectable choice of banking options, 24/7 support, and naturally a spectacular selection of online slots. Some players actively seek out games from specific developers such as Play’n GO, NetEnt or Yggdrasil. Other players want regular promotions and a community to feel part of.

We cover all these factors in our thorough reviews, so do take the time to read through them to determine which slot site sounds best for you.

How we rate and review slot sites

Thankfully, we’ve done all the hard research and narrowed down the best slot sites that are all licensed by the UK Gambling Commission, so you can rest assured that any slot site we recommend has undergone the necessary audits for safety and security, and is trustworthy and reliable. At Slot Gods, we have an intricate review and audit process to ensure that all slot sites we list on our website offer value in multiple areas which we highlight in the review.

During our reviews, there are six main categories that we specifically consider: Design, Usability, Games, Promotions, Banking and Support.

Of course, we start with the visuals of the slot site to ensure it holds up to a certain standard.  After this, we ensure the slot site user friendly for both desktop and mobile meaning that you can play anywhere, at any time, on any device you choose.

Then our focus is turned to the games available such as the selection of online slots and whether they are from reputable and highly regarded developers. Additionally, the reviews briefly dive into other games available such as live casino games or Slingo - as sometimes we all want to play something a little different.

Once we’ve ensured that the choice of games and overall platform is respectable - we look towards the promotional side of the slot site to see what’s on offer for players. Finally, we cover the banking and support options available at the slot site, including any hidden charges or fees, and report on any findings in our review.

To make it easier to digest, we sum up the scores from each category to result in an overall rating that can be found at the top of the review. This is perfect if you are wanting to get an overall gist of the slot site before deciding to play there.  However, remember that a lower score in one area doesn't mean it hasn't scored highly in another, so referring to the category scores might be more useful to some of you.

Which slot site is best for you?

First and foremost, it helps to have at least an idea of what you are looking for in terms of your gameplay. If you are looking for a slot site filled with an incredible selection of thousands of games at your disposal, then it’s easy to highlight Videoslots Casino.

Alternatively, you could be a player searching for a decent selection of online slots, but mainly with a focus on promotions to get more out of your gameplay. If this is you, then we'd recommend PlayOJO Casino due to its amazing Kickers promotions.

Prefer a recognisable mainstream brand with years under its belt? Then we'd recommend Paddy Power, Party Casino or Betfred Casino. They might not offer the widest selection of online slots, but they have all the most popular and familiar slots including most branded slots. Paddy Power also has a strong focus on daily jackpots, so if that rings your bell then check Paddy Power out now.

Benefits of slot sites over land-based casinos

There’s no denying that slots are thrilling but what are the benefits of playing them at slot sites compared to land-based casinos. To begin with, the selection of online slots is absolutely brilliant with so many different themes and developers literally at your fingertips.

Alongside the variety of online slots, you’ll find that there are even more mechanics online such as Gigablox and Infinity Reels that you won’t find on land-based slots.

There is also the added bonus of better RTP with online slots. The RTP is essentially how much of the total amount wagered on the slot is paid back to players with online slots averaging an RTP of 96% whilst land-based slots can vary between as little as 70% and 90%.

Additionally, you’ll find that you can play anywhere you want meaning that you can play online slots whilst you are travelling on the bus or at home in your pyjamas.

The final reason as to why slots are better played online is due to the bonuses available such as free spins and deposit bonuses, leading to more bang for your buck.
