How we choose the best slot sites in the UK
With over two decades of experience in the gambling industry, the team here at Gambling Zone know how to spot a quality slot site. Any online slot site here has been personally tested and assessed based on our strict criteria.
We look for a wide variety of slot games, as well as other factors. Here we take a closer look at each. If you would like a more detailed explanation of the factors we look at when assessing online casino sites and betting sites please visit the Gambling Zone Review Criteria page.
Free Spin Bonuses
Free spins are a perfect promotion for online slot fans because these are specifically for slots. These can be welcome offers, as well as ongoing bonuses.
The best slot sites offer free spin bonuses on top slot providers such as Play ’n Go, No Limit City and Quickspin. It is important that there are fair terms attached. The bonuses we recommend are reasonable and fair, and we keep track of any changes to them in our reviews.
Customer Support
We check for slot sites that offer a range of support options. These include live chat, email, phone or social media channels. 24/7 live chat is our top preference because this allows us to get assistance at any hour of the day or night.
We also like to see multiple language options. Getting assistance in your native tongue is always better and it can help avoid any mix-ups. Response times are one of our main criteria.
Payment Methods
It is important to consider the range of payment methods before depositing. In the UK and Canada, some of the most popular payment options include PayPal and Interac.
Both offer players a secure way to deposit and withdraw from slot sites. Using PayPal, slot players can securely transfer funds instantly and without providing their banking details. Interac is an online payment system that allows customers to securely send money within Canada or internationally.
Fully licensed and regulated
At Gambling Zone, we only recommend slot sites that are fully licensed and regulated in their respective territories. In the UK, slot sites must be licenced by the UK Gambling Commission (UKGC). Slot sites in Canada must have an AGCO licence issued by the province of Ontario.
Slot sites can also be licensed by the Malta Gaming Authority (MGA). MGA licences are recognised internationally. Our team highly recommends slot players look out for these when choosing their online slot site.
Responsible Gaming
Responsible gaming is a key priority at Gambling Zone. We only recommend slot sites that have implemented responsible gambling policies and procedures, such as having tools in place to allow players to set limits on their play. Many slot sites go beyond the legal requirements by providing players with free self-assessment tests, and access to external support services, as well as offering session, deposit, and loss limits.
We encourage players to use any tools available for limiting their play and never gamble more than they can afford. Responsible gambling is one of our biggest commitments and all of the slot sites we mention promote tools, and adhere to laws in their territories.
Does the site have the best online slot games?
A good slot site offers quality over quantity. Of course, we like to see a variety of game providers, however, we are more focused on ensuring the software is well-known and reputable. A blend of premium providers such as NetEnt and Red Tiger, and indie options such as Yggdrasil are ideal.
Jackpot slots are also important. The best slot sites will have games like Mega Fortune and Hall of Gods. The best online slot sites will also showcase exclusive titles. These can be new games available on early release, or slots that have been made specifically for that slot site.

Top 5 Best Real Money Slot Games
Here is a list of the top 5 most highly rated online slots in the UK as per our expert's choice. From lucrative bonus rounds to fun mechanics and innovative features, these slot games will take your gaming experience to another level. Find out more about each slot below.
Most Common Types of Slots at the Best Slot Sites
Online slot games are a popular form of online gambling and have been for many years. Technological advancements have brought slot games to life with stunning graphics, interesting themes, and multiple in-play bonus rounds. Real-money video slots have changed the way in which we play slots online, and there are now so many varieties.
In this section, we will break down the different types of slot games available so you can make an informed decision when selecting your next slot game. We will discuss what makes each type unique and provide insight into what you can expect when you play.
3 Reel Slots
3 reel slot games are a classic slot style; if you can imagine a fruit machine in the amusements then these are an online version. They feature a standard slot machine design with three spinning reels and typically one to five paylines. 3 reel slot games have only three vertical rows of symbols, making them a straightforward and easy-to-understand slot game for beginner players.
In terms of features, you may come across a nudge or free spins, but nothing too complicated. 3 reel slots can offer exciting gameplay and graphics. While new players may wish to start their online slot experience here, seasoned players can also enjoy the simplicity of the games.
5 Reel Slots
Five-reel slot games are the most popular type of slot game and account for the vast majority of online slot games. They offer a higher level of excitement compared to three-reel slot games with their increased payline possibilities, depending on your stake. These slot games also have more bonus features like scatter symbols, wilds and advanced free spins.
Popular titles such as Starburst and Gonzo's Quest are among the most played 5 reel slots due to their stunning graphics, immersive themes, and exciting bonus rounds. Five reel slot games are an excellent way to experience the best that online slot gaming has to offer with great graphics and expansive bonus features that can boost your bankroll in one spin.
Progressive Jackpot Slots
Progressive jackpot slot games are a type of slot game that offers players the chance to win huge sums of money. These slot games feature progressive prize pools, which means that each time someone plays them, from any slot site, the pot increases. The more people play, the bigger the rewards get and this can lead to amounts in the millions.
For those looking for more frequent payouts, there are daily jackpot slot games available too. These work similarly but with smaller prizes on offer every day.
Cascading Reels Slots
Unlike traditional slot games, where reels spin in order to create a winning combination of symbols, cascading reels usually fall from above in what is known as the Avalanche feature. This can give slot players multiple wins on one spin.
The feature allows slot players to score even more wins on a single spin as any successful combinations will disappear and make room for new symbols to drop down. The Avalanche feature is also commonly referred to as Rolling Reels or Tumbling Reels depending on which game provider you are playing.
Megaways Slots
Megaways slot games are a relatively new game mechanic in the slot industry, first created by Big Time Gaming in 2016. This type of slot offers players the chance to experience huge variability with every spin. Instead of having traditional slot reels with fixed numbers of symbols, Megaways slot games feature random numbers of symbols within each reel. The maximum number of paylines available in Megaways slot games is 117,649 but this number varies depending on how many rows appear in each reel and how much you stake.
Megaways slot games are incredibly popular among slot players looking for something different. The bonus features make these slot games attractive to players. The cascading reels feature found in most Megaways slot games adds greater unpredictability due to its additional multiplier system which increases winnings exponentially with successive wins on a single spin.
Slingo Slots
This hybrid slot game is a combination of online slots and bingo, giving players the best of both worlds. Players must spin reels to form winning combinations that fill in numbers on their bingo cards. As with slot games, there are bonus features such as wilds and scatters for extra chances at winning, Additionally, many Slingo slot games offer progressive jackpots for those looking for bigger potential wins.
Virtual Reality Slots
With a combination of immersive visuals and sounds, slot players can experience slot games as if they were playing in a physical casino with virtual reality slots. In VR slot games, slot players are transported to slot game worlds where they can explore and interact with slot games in a 3D environment.
This is an exciting slot experience that allows players to become further immersed in the theme of their slot game. VR slot games are still in their infancy, but developers such as NetEnt have already started developing slot titles for this technology.
Best RTP Slot Games
RTP stands for Return to Player and it is an important measure of slot game performance. It refers to the percentage of money wagered in a slot game that is returned to players as winnings over a period of time. For slot players, the higher the RTP of a slot game, the more likely they are to win.
We should note that it is a theoretical return and not a guarantee. But slot players should always look out for slot games with higher RTPs as these offer better value and potentially more money in your pocket. As a standard, the RTP will range from around 94%-98%.
Popular Slot Themes
Slot games come in a range of engaging themes, offering slot players the chance to explore different worlds through slot gameplay. From classic slot games with fruity symbols to more modern slot games featuring fantasy worlds.
The most popular slot themes include adventurers with slots such as Gonzo's Quest and Book of Dead leading the way. Animal slot games are also popular, with slot players having the opportunity to explore the African Savannah in slot games such as Mega Moolah.
Fantasy slot games are also incredibly popular. Games include Fire Joker and Reactoonz, which have become firm favourites thanks to their exciting casino bonuses and lucrative prizes. Irish and ancient Egypt also provide dozens of slot themes with the Rainbow Riches being among the most played online slot game in the UK.
Egyptian
The ancient Egyptian civilisation continues to fascinate and inspire us. It is no wonder that many slot providers have looked to Egypt when designing their games. Many Egyptian slots, such as Cleopatra, take place thousands of years ago when the civilisation was at its peak; others, including Book of Dead, have a present-day setting and feature an archaeological theme.
Fruit
The first physical slot machines typically had fruits as their symbols. These games also had few paylines and no special features. Many providers of online slots base their creations on the earliest slot machines, giving them a fruit theme and stripping back the gameplay - Classic Fruit is a prime example.
Irish
Rainbows, leprechauns and pots of gold are common features in Irish online slots. These games are usually jolly and upbeat, celebrating all things Irish with exciting gameplay and plenty of special features. Rainbow Riches is a series of over two dozen slot games that focus on Ireland, each one offering different features.
TV Shows
Quite a few online slots draw inspiration from hit TV shows. Game of Thrones and Stargate Megaways are just a few slots that bring the characters, worlds and storylines of popular shows to life. These immersive games have exceptional design and come with plenty of special features. Play a TV show slot and see your favourite characters on the reels.
New Online Slot Games
New slot games are released every month by leading slot developers, such as NetEnt and Play 'n Go. In our experience, the biggest providers can release up to five new slots a month which is phenomenal. It is a great time to play slots as developers will be pushing the boundaries with the latest technologies and creative ideas.
Some of the best slot sites in the UK will have deals with software providers to get exclusive early access to slot games and offer them first. So slot players should always check out the slot sites we recommend to see what deals they can get on new slot games.
At Gambling Zone, we also regularly update our list of the best new slot releases with in-depth reviews of each title.

The best online slot is therefore a matter of personal preference. Popular titles such as Rainbow Riches, Book of Dead, Gonzo's Quest and Mega Moolah are the highest-rated, and most played in the UK thanks to their engaging themes and exciting bonus rounds.
At Gambling Zone we provide an in-depth breakdown of some of these popular slot games so that you know exactly what to expect when you load the game.
Free Spins Slots
Real money video slots are well known for their bonus rounds and in particular free spin rounds.
Free spin rounds or bonuses offer slot players the chance to spin reels without having to use their own money which is why it is a sought-after feature.
While these slot games can come with higher variance, slot players can win big in free spins slot games due to the multipliers and extra wilds available in some slot titles. Many slots even require the free spin round to be unlocked to be able to get to the maximum payout of the slot.
Plus, there are plenty of online gambling sites that offer free spins bonuses when registering or reloading your account which allows slot players to enjoy free spin rounds on specific slot titles.
At Gambling Zone we have compiled a list of our top picks for the best slots with free spins so you can experience all that this popular bonus feature has to offer.
Popular Slot Game Providers
Pioneers of video slots include NetEnt, Evolution Gaming, Play'n GO and Big Time Gaming. These slot game providers have created some of the most iconic slot titles in online slot gaming history. Features such as cascading reels, Megaways slot games and virtual reality slot games have all been created by the best game studios and they set the bar in slot gaming innovation. At Gambling Zone, we provide slot players with a comprehensive breakdown of leading slot game providers. This way you can know what to look for when you join a slot site in the UK.

These online slot tournaments take place during a specific time period. It could be a few days or even a month or longer.
