How We Choose the Best Slot Sites

There are many factors that we consider when we examine and rate UK slots sites. We certainly think about things that inexperienced players usually don’t think of such as customer service, certifications from testing labs, and the diversity of game catalogues.

Going over all of our criteria would stray too far from the purpose of this guide. However, we will explain five of the most key traits that we look for when assessing the best slot sites in the UK.


Do you want to ensure that you are treated fairly when you play online slots and other real money games? Do you want to be confident that the UK slots sites that you play at will pay you when you win without any hassle? Well, you can be sure of these things when you only play at online casinos that are licensed by the United Kingdom Gambling Commission.

The UKGC is one of the strictest and most reputable gambling regulators on the planet. They make sure that any online slots sites that they licence operate to the very highest industry standards. That includes providing the highest levels of security as well as tools and resources to help you play responsibly.

We strongly urge all fans of online slot machines to avoid playing at unlicensed or foreign slot sites. This will ensure they are afforded the best player protection and a safe playing environment.

Privacy & Security

UK residents who open an online casino account and deposit funds are required to provide a variety of personal information and sensitive banking details. In a world in which this type of information is extremely valuable to scammers and fraudsters, it’s crucial that you can trust your online casino to protect this data.

The best online slots sites make sure that your private information is never compromised. They make use of the most modern internet security technology including SSL encryption, firewalls, and other layers of electronic and human safeguards. To keep it simple, licensed UK slot sites offer the same levels of security as big banks and other major institutions.

User Interface

It’s easy to get lost in land-based casinos. However, that is never the case when you play at top UK slot sites. Modern online casinos are designed for easy navigation on personal computers and mobile devices. You should be able to easily find the game you are looking for as well as anything else you need access to like your banking section and active bonus offers.

One thing about today’s top slot sites is that they are configured for mobile devices. This is because so many people prefer to use devices like tablets and smartphones to play online casino games. These mobile slot sites and the games look great and are easy to find your way around even if you are a beginner.

Software Providers

Online casinos wouldn’t exist if it wasn’t for the many talented software developers that are responsible for creating the best slots to play. Software studios like Microgaming, NetEnt, Pragmatic Play, and BTG are just the tip of the iceberg when it comes to top developers. Some of the best online slot sites feature dozens of software providers which enables them to offer a bigger selection of slot games and other casino games.

One of the benefits of playing at slot sites that feature big providers like Microgaming and NetEnt is that they can offer some of the biggest progressive jackpots. The biggest payouts in online casino history have been won on games like Mega Moolah, Divine Fortune, and Major Millions. On top of that, these premier software developers focus on offering a high-quality product that is mobile-compatible. They are always releasing innovative new casino games giving you more features and options to choose from.

Bonuses and Promotions

Even though bonuses and promotions aren’t the most important things to consider, they are still a critical element of any online casino review. There are a lot of truly great bonuses available right now that can help boost your bottom line. It isn’t difficult to find welcome bonuses that offer bonus spins, bonus cash, or free play.

In addition to welcome bonus offers, the best slot sites offer an array of regular promotions for existing players. This means more bonus cash, more bonus spins, and lots of other goodies like cashback special events. A good VIP program and loyalty rewards offer even more perks and benefits.

Perhaps the most important aspect of any bonus offer is the wagering requirements. You see, you can’t just claim a bonus and cash it out right away. First, you need to spend some real money playing slot games. The wagering requirements tell you how much money you need to bet. The lower the rollover, the easier it is to satisfy the wagering requirements. Be sure to understand any other limitations and restrictions that apply to any bonus you are interested in claiming.

Pros & Cons of Playing Casino Slots Online

It doesn’t matter if you visit an online casino or at a brick-and-mortar venue, slot games almost always attract the most action. This is why online casinos typically offer significantly more slot games than any other type of casino game. Of course, playing online slot games comes with advantages and disadvantages. Let’s take a look at a few pros and cons of playing slot games.


  • Accessibility: Slot games have never been so easy to access as they are today. All you need is a stable internet connection and a PC or mobile device. You don’t even have to download any native apps or casino clients. You can simply log in at the best online slots sites and select the games you want to play. They will load right in your browser, run seamlessly, and amaze you with vivid HD graphics and sounds.
  • Potential to win life-altering jackpots: Unlike other popular casino games like blackjack and roulette, online slots give players a shot at some very large payouts. This is especially true if you play progressive jackpot slot machines. Some lucky players have won jackpots worth over £20 million!
  • Entertainment: One of the main benefits of playing online slots is that they can be highly entertaining. The diverse themes, variety of bonus features, and the storylines ensure that you never have a dull moment. Remember that you don’t always have to play for real money. The best slot sites allow you to play for free using play money.
  • No skill required: Playing slot games does not require any skill unlike casino games such as blackjack and casino poker variants. It really all boils down to luck. You stake your wager, smash the Spin button, and wait to see how it all shakes out.
  • Maximum Rollover Value: When you are attempting to reach the wagering requirements for a bonus, online slot games always contribute the largest percentage of each bet. In most cases, 100% of each bet on slot games goes toward the wagering conditions. On the flip side, only about 5% to 20% of each bet you place on table games goes toward the rollover.


  • Lack of interaction: It’s pretty easy to “get in the zone” when you are playing a slot game. As such, playing an online slot game can be somewhat isolating. You don’t even get to interact with a dealer let alone anyone else.
  • Losing streaks can be demoralising: Whilst everybody who plays their favourite slot game dreams of winning big, a lot of them end up taking losses. What’s worse? Going on an extended losing skid. This happens quite often and, when it does, it can be utterly demoralising.
  • It’s too convenient: Yes, convenience is one of the main advantages of playing slot machines online. However, it can also be a disadvantage. This is especially true if you don’t always play responsibly. Some people simply can’t resist the urge to pay homage to their online gambling lords at all hours of the day and night. Please gamble responsibly. Know when it’s time to quit and focus on something else.

Variety of Online Slots Games

Slot machines might look the same, but there are actually a few different types.

Video Slots

Video slot machine games more or less encompass all online slot games. The games are designed with a wide range of reel and slot layouts as well as features like wilds, scatters, free spins, and mini games.

Unlike the old-school slot games that were mechanical, a modern online slot machine is controlled by a random number generator which is essentially a computer program. To ensure ongoing fairness, top-tier UK slot sites have their RNGs regularly tested by accredited casino software auditors like GLI, iTech Labs, and eCOGRA.

Branded Slots

In a nutshell, a branded slot machine is one that is licensed by a third-party. This typically applies to games based on movies, television, and music. For instance, you have probably heard of the Walking Dead slot game? It’s one of Playtech’s biggest hits. Anyway, the creator had to get a licence and express permission to feature characters, animations, and sound bytes from the show. Other examples of branded slot games would be:

  • Stargate Megaways
  • Def Leppard Hysteria
  • The Goonies Return
  • Narcos
  • The Invisible Man

Jackpot Slots

If a slot game ever makes headlines, it’s probably a jackpot slot. And it’s probably just paid out a huge jackpot worth millions. There are basically two types of jackpot slots. Stand alone jackpot slots and connected jackpot slots.

With the stand alone variety, a portion of every bet contributes to a jackpot that keeps growing until it’s won. With connected progressives, several slot games are connected on a network. A percentage of every bet on every slot machine on the network contributes to a common progressive jackpot which keeps building until it has been won. As a rule, connected progressives build the biggest jackpots.

Slot Site Payment Methods & Withdrawal Times

There are several excellent payment methods available to online slots enthusiasts in the UK. In case you haven’t heard, UK slot sites can no longer accept credit cards. Fortunately, you can still use a debit card for deposits and withdrawals.

You should find that most payment methods facilitate instant deposits. However, you should be aware that not all payment methods can be used to withdraw. Moreover, those payment methods that do support withdrawals offer different withdrawal times. Let’s go over some of the best two-way payment methods and their average withdrawal times. Of course, you have to consider that these times do not include any pending periods that your online casino may or may not require.

Payment Option Average Withdrawal Time

  • Debit Card 3 to 5 days
  • Online Banking 3 to 5 Days
  • PayPal 0 to 2 Days
  • Skrill 0 to 2 Days
  • Trustly 0-2 Days
  • MuchBetter 0 to 2 Days
  • Neteller 0 to 3 Days
  • Wire Transfer up to 10 Days
  • Check by Mail up to 21 Days

Real Money Online Slots

The definition of a real money slot game is self-explanatory. It is simply a slot game that offers real money payouts. It’s the exact opposite of a play money slot game that only rewards you with play money. As a point of interest, most real money slot sites allow you to play the games for virtual money if you just want to try them out or get a free fix of entertainment.

Best Real Money Slots

It’s difficult to come up with a list of the 10 best slots because there are so many interesting games to choose from and everybody has different tastes. Nevertheless, here are our top 10 picks.
