The Best UK Slots Casinos for 2023

As we mentioned earlier, we put every operator through some rigorous testing procedures before listing them as one of the best UK slots casino sites. So, if you don’t feel like reading about each checkpoint in-depth and would rather skip to sliding around on the shiny interfaces of the best UK slots sites, then simply press the button ‘Try Your Luck’. A new tab will open, and you can head to any of the recommended casino sites for UK players anonymously.

However, if you’re curious, please keep reading! On this page, we explain exactly what criteria we use when searching for the top-rated UK online casinos for slot machines. We also provide you with a handy little guide at the bottom that allows you to compare our top ten rankings easily. For now, let’s start with safety because it should always be your number one priority!

Top Safety Features

The first thing we look out for when choosing the best UK slots online casinos is safety. There are dozens of factors we consider, such as licensing, security, alternative gambling services, customer support and much more. You can get an idea about all of our safety checks from the paragraphs below.

Casino Security – Making Sure the UK Slot Casinos Are Safe

Before even considering listing a casino site among the best UK slots, we make sure that its security measures meet our standards. That includes 128-bit SSL encryption technology at a minimum, which will ensure that all your personal details and transactions are stored safely. Furthermore, we make sure that the casino uses firewall technologies, protecting it against hacker attacks and unauthorised access. Another thing we take into consideration is whether they offer additional protection options such as safe gambling tools and self-exclusion features.

UK Gambling Commission Licensing

But even the strongest security systems cannot make up for a lack of a valid UKGC license . To operate legally in the United Kingdom, online casinos must have a permit by the UK Gambling Commission, and only then will they be considered trustworthy by us. We double-checked the permits of all the recommended operators for delivering UK slots and found that they all hold a valid licence. They have unique numbers, which you can see in the table on this page.

A UKGC license guarantees that the casino offers fair gameplay, protects your data, segregates your deposits in separate accounts and battles problem gambling by partnering with responsible gaming organisations. In short, a legal casino site will do everything in its power to keep you, your money and your personal information safe and sound.

Reputable Software Developers

Many of the best UK slots online casinos have excellent reputations due to the software developers that power their platforms. Microgaming, NetEnt, Playtech, Play’n GO, Yggdrasil Gaming and Evolution are examples of companies with great portfolios and years of experience.

These software providers have built reputations for developing fun, safe, honest and fair titles over the past decades. If an operator has games from those providers, it usually means that the website is trustworthy and reliable. Still, remember that having only reputable software developers doesn’t mean that the casino can’t scam you. Always make sure that the platform holding the .

Plenty of Payment Methods

Nowadays, a reputable operator needs to offer a wide range of payment options so that players with different preferences can deposit. Some people prefer debit cards, while others rely on e-wallets, prepaid cards, or they might want to make a Boku mobile payment. The more methods available at an online casino, the better.

You should also make sure that the include your preferred method, along with clear terms, conditions, and requirements regarding minimum/maximum limits, processing times, fees etc. The most trustworthy casino sites will provide detailed instructions on how to make a deposit.

Real Money Slots Bonuses & Promos

While not completely fraud-free, you can usually tell a scam bonus offer from something legitimate quite easily. First of all, real money UK slots casino bonuses should exist. Having slots but no welcome bonuses that allow you to play them without risking your own funds straightaway is odd. It could also be a red flag if the promotion requires an absurd deposit to unlock or comes with extremely high wagering requirements.

Let’s say you find a site offering a bonus that seems too generous to miss out on. Before signing up, check the small print for any restrictions that could render the deal almost useless. Consider things like the wagering requirement, the expiry date, approved payment methods, eligible games, and the minimum deposit limit. If any of these don’t match your intentions, try the next offer instead.

If you aren’t sure which slots to pick when using an offer, rest assured that the best casinos will highlight which games contribute towards the playthrough. An added bonus is when the site provides dedicated bonus slots pages for each offer, highlighting what slots you can use the free cash or spins on. Our recommended sites above feature the latter and are generally rated highly across the web.

Overall, it takes time to spot the best UK slots casino bonuses, but it is worth taking the time to scan the T&Cs yourself. When you have done this enough times, you will quickly spot the deals that are likely to suit what you are looking for. If all of this seems too much hassle, don’t worry, as we also list some of the best casino promotions available to UK slots players on this page.

Which Is the Best UK Online Casino Bonus for Slots?

We’ve analysed hundreds of welcome offers, and after hours of comparisons, we found that the stands out with its slots bonus. Not only is the bonus money rewarded on the first three deposits, but it also comes with very low wagering requirements of just 35x. You also have a huge 30 days to work through the playthrough compared to the industry average of around 30 days.

The second-best bonus for playing slots goes to , which welcomes you with a 100% matched bonus of up to £300, along with 77 free spins. While this may seem less generous than the previous slots bonus once you get past the initial deposit, you’ll get to claim 10 free spins to use on a sliding scale for nine more days. This gives you two weeks to try out the casino and its library of slots before deciding if it is for you. As a side note, you should know that both casinos are compatible with all types of smartphones, meaning you could also .

How Do I Claim My Bonus?

UK Slot Sites with No Wagnering Requirements

Wagering requirements are the number one enemy of many slot fans. These playthrough targets can vary between 20x your total sum of bonus money and even climb as high as 70x. The good news is there are still some slots offered by UK online casinos that come without any wagering requirements on the winning amount.

Each tranche of 10 bonus spins can be used on a specific day of the week, giving you a full year of regular boosts to your bankroll.

The runs occasional offers that allow you to grab bundles of free spins. We particularly liked the recent offer that gave you a spin of the Mega Reel on the basis of depositing £20. The range of possible prizes included up to 500 free spins on selected slots, including Fluffy Favourities and Starburst, along with other chances to win massive amounts of spins. Of course, any winnings arising from these promo spins will be subject to Paytm Casino wagering requirements of 65x.

Any winning from these spins are paid as a bonus, and subject to 40x wagering.

Available Game Variations

Of course, the primary reason why we bet is to have fun. After all, making money is not our main intention (otherwise, we would open an investment portfolio). Since we are talking about fun, what could be more entertaining than pulling the machine’s handle and watching the wheels spinning? That’s right – nothing! Slots are the kings of entertainment at online casinos, so we suggest looking for a platform with plenty of those.

Furthermore, since we are specifically talking about the , we made sure that all of the recommended operators offer games that are favourite among British punters. Many of our top slots casino online operators have thousands of different slots in their collections. The game catalogues include classics, video slots, fruit machines, progressive jackpot slots, and more.

We must point out that sometimes the sheer size of a catalogue can be overwhelming. If you are a beginner, it might be best to look for a less extensive collection that has been hand-picked for quality. If, however, you enjoy variety and exploring new releases, you will certainly find your niche at one of our larger-listed sites.

Aside from slots, you should also consider the availability of other games. Even though you are visiting a reel-spinning site, there is a chance you might fancy a break from slots and try something different. If the casino offers roulette, blackjack, poker, scratchcards, keno, or other , it will add points to its score. However, bear in mind that some slots sites only focus on providing quality slots, and that’s perfectly fine.

Live Dealer Casino Games

Many British casino gamers are attracted to the live dealer versions of popular table games. The best UK slots sites typically offer live roulette and live blackjack, along with casino poker variants. We have reviewed the software platforms used and the quality of streaming for live casino games at many sites. Generally, those offering slots are equally adept at supplying first-rate live tables. However, if this is an essential element for you, we recommend reading our guide to the and our top 10 rankings.

When it comes to online gambling, security is the number one concern. Yet playing at live dealer tables actually involves greater risks than other forms of remote casino gaming. After all, the integrity of any game relies heavily on the honesty of the dealer, who is visible to players via a live video link.

Casino Bonus Offers & Promos

One of the biggest reasons to play online slots is to claim a hefty welcome bonus and turn that extra credit into big wins. We’ve reviewed many offers to find the best deals available to UK players. We looked closely at the welcome packages of the top online casinos to find the ones that give you the best chance to win real money.

As part of our ranking system, we assign higher positions to sites awarding bigger bonuses, especially when they carry lower playthrough requirements. We also favour slot-specific bonuses that can only be used on the reel-spinners. Such offers will give you maximum value if slot games are your chosen casino activity.

It is important to read the terms and conditions attached to all bonus offers. The best sites will clearly state which slots contribute to playing through any wagering requirements. You should also check the value of the games at 100% as this indicates which games will return the largest portion of your wager to your betting balance. Find out more details in our dedicated guide to the .

If you tire of playing with bonus money, most sites will enable you to opt out of marketing emails. Otherwise, you can expect to receive regular invitations to take advantage of further promotional offers. These often include reload bonuses, free spins, and prize draws.

Software Platform Quality & Availability

In order to deliver high-quality games and a smooth-running platform, the best online slots casinos UK rely on software provided by specialist companies. These developers employ teams of designers, mathematicians, musicians, sound engineers and producers to create individual games tailored to each casino client. Here are some of the biggest names supplying software platforms to many UK online casinos for slots:

Many of these companies also develop live dealer casino games. As the two activities have little in common, some casino sites focus on one type of supplier to simplify the management of their platform. It’s worth noting that a site relying on just one provider can still offer a diverse choice of games. NetEnt is the most common software brand featured at online casinos for slot players.

Nevertheless, some of our top-ranked slots sites feature none of these providers, demonstrating that their own merits outweigh the benefits of associations with big-name software developers. takes this approach, relying on its own bespoke platform to offer a curated selection of slots from smaller developers, such as Mad Scientists, Ice Caves, and Jewel Box.

Number of Software Providers

Having the most popular slot developers is crucial for an operator’s success, but it isn’t everything. Diversity is also extremely important since it shows that a casino site cares about quality. Most of the offer titles from multiple providers, giving you access to thousands of games developed using the latest technology.

If you wonder how we check how many software providers there are at a casino, the answer is simple – the footer. Most platforms have a list of partners in the bottom of the page. Alternatively, you can use the FAQ section or contact customer support for assistance. In the table below, you can see how many software providers are behind our top 10 slots casino online recommendations.

Even though slot sites don’t necessarily need to offer sports betting markets or virtual poker tournaments, adding some diversity wouldn’t hurt. A good compromise would be to combine slots with other casino games, such as scratchcards, video poker, wheel of fortune styles games, and live dealer games. Below, you can see the number of game categories available at our top 10 slot sites.

Average RTP and Payout Times

Win rates, house edges, and RTP rates are critical indicators of a casino’s generosity and the potential returns you can expect from your bets. The abbreviation RTP stands for Return to Player and represents the percentage of stakes returned as winnings over a long period of play. All things being equal, the higher the RTP, the better the deal for the player.

However, it is important to distinguish between game RTPs and those relating to casino offers and site-wide play. The best UK slots casino online in our top ten have site wide certificates from independent authorities, such as eCOGRA, verifying typical payout rates for the range of games offered. In general, a rate of 95% or higher is considered good, and many of our top sites achieve this or surpass it. You can see the average payout rates achieved by our top 10 in the following list:

PlayOJO — 97%
Yako Casino — 96.6%
Greenplay — 96.4%
Karamba — 96.3%
Mr Vegas — 96.3%
Slotango — 96.3%
The Grand Ivy — 96.1%
Playzee — 96.1%
Casimba — 95.8%
Slot Angels — 95.8%

Please bear in mind that the average payout rates shown above relate to long term play over millions of spins. The actual results you achieve over a short period will inevitably differ widely from these averages. No matter how good the RTP is, losing money quicker than you can afford it is still a possibility.

No respected casino site tries to lure customers in with excessively high win rates. Therefore, acceptably low RTP rates are quite common among the best UK slots sites, as demonstrated by our top ten rankings.

The speed at which you receive your slot winnings varies depending on the choice of payment method used. E-wallets such as PayPal, Neteller, and Skratch offer the fastest withdrawals, taking just a few hours for the casinos to process the transaction and up to 48 hours for the e-wallet to complete the transfer.

By contrast, debit cards can take up to five working days for both operator and bank processing. Boku withdrawals are limited to £30,000 per day and are shared out over 10 separate transactions. Plus, you will incur an admin charge of 15% for the privilege of using this mobile phone bill payment method.
