How We Pick the Best Slot Sites UK

When selecting the top slot sites in the UK, our primary goal is to do right by our readers. We want you to have the best possible experience, but the clear choice isn’t easy if you’re not a casino expert. There are many casino sites out there, but not all of them are equal in what they offer customers, or even how they treat them.

Our rigorous assessment of casinos is built on the foundation of transparency, fairness, and trust.

Here’s a breakdown of what we look for:

  • Licensing and Regulation: Licensing and regulation isn’t an overly exciting discussion point, but it’s a very important one. The first thing we look for is legitimacy. The best slot sites in the UK must be licensed and regulated by the UK Gambling Commission (UKGC). An accredited stamp of approval from the UKGC means that the casino adheres to strict standards of player protection, fairness, and financial security.
  • User Experience: A good user experience is vital. In 2023, you want each and every website to be perfectly optimized for your mobile phone. Most of us use them as our sole device for internet connectivity, and if a website isn’t optimized, then we simply will not use it. The best casino sites in the UK must have a great design, seamless mobile compatibility, fast loading times, and ease of use for a populace of people who simply will not accept less.
  • A Great Game Selection: The best slot site wouldn’t be the best without the best selection of games. To the average player, slot providers and what games they make are one and the same, but we know them well, and we know who makes great games. When we’re looking for the best slot sites, we’ll check for slots from the best providers
  • Bonus Offers: The best slot sites offer the best slot offers, it’s as simple as that! We want to see great bonus offers with fair wagering requirements and free spins on great games.
  • Customer Support: Customers are everything, and satisfaction should be a top priority of every casino. Friendly, efficient, and professional customer service agents should be available to help players with their every need.
  • Payment Options: The best UK slot sites should have the best payment options too. Visa and Mastercard are must-haves, and innovative payment methods like PayPal, Google Pay, and Apple Pay are great indicators of a slot site that is making every effort to cater to modern customers with modern payment methods.
  • RTP: The impact of RTP is highly debated because of how it’s calculated, but why not give yourself the best chance? We look for high-RTP slots and fair odds before we recommend a casino to players.

Best Online Slots Sites September, 2023

Many casinos can claim to be the best, but they’ll need to meet certain criteria if they’re to be considered in our eyes.

When we’re looking at the best slot sites, we’re not just looking for a site with the best game selection and the highest RTPs, but other things like security, ease of use, bonus offers, mobile compatibility, and customer support.

Each of these things is a cog in a machine as important as the one before it, and to really be the best, a casino must consider every aspect for a seamless experience for their players.

In this article, we’re talking about what we look for in the best online slot sites and how you can avoid casinos that aren’t up to the standard that you deserve as a player.

What Makes the Best Online Slot Sites?

There’s a reason why some new slot sites are now more famous than companies that have been around since 2000. Sure, they might be spending more on advertising. But in many cases, an excellent online slot site checks out all of the boxes below.

A Safe and Secure Website

If you’re like many people, you are careful not to visit an unsafe website. That means you avoid sites that lack SSL encryption (padlock sign). You are cautious about casinos that don’t accept well-known payment methods or have no PCI compliance.

On the flip side, you probably also prefer casinos licensed by the UKGC. Some people might want operators that have been publicly audited by Independent Casino organizations such as eCOGRA, iTechLabs, and Thwarte.

Collectively, these features confirm whether a site can be trusted or not. Obviously, you want a casino with all the certificates mentioned above to be sure it’s safe.

Your details are precious, after all. There are plenty of people who would use your details for their own illicit gains, given half the chance. We know an online slots website is exciting, but due diligence is required before you commit to anything, and security is at the top of the list.

Neatly Designed & User-friendly site

Although it’s not the most essential feature, a website’s design can make you like or hate a casino. If it’s eye-catching with a beautiful colour scheme and is well-organized, you will want to stay there for a while.

Mobile Compatibility

Mobile compatibility on the best slot sites is an absolute must. The internet is overwhelmingly catered towards mobile users in recent years because of the sheer number of people that use them.

If you asked 10 random people what they use to browse the web, then 9 of them would probably say their mobile phone.

Smartphones are certainly the future, which means they’re the future of the web too. The best online slots sites absolutely must create a website that is easy and appealing for mobile users.

Best Casino Slots UK

In contrast, if a website takes forever to open, some menu items don’t respond, or it doesn’t operate on your smartphone, you won’t want it. That’s why it’s best to use a casino that has been tried and tested.

What’s more, it must have top ratings that provide proof it’s reliable for online gaming. Another critical factor is having policies that protect players if a game crashes and their winnings are confiscated.

Slot Variety

You are looking for slot sites in the UK, right? Naturally, you want a casino with an impressive variety of games. Most people choose operators with popular slots. However, it’s increasingly becoming a trend to also try new slots from upcoming developers.

As such, don’t pay all your attention to a few well-known slots. Instead, look at the game diversity so that you will have a chance to play various types of slots at the same casino: Megaways, classics, 3D, video slots, and branded games, to name a few.

Slot innovators are constantly finding ways in which to change the game. A few years ago your idea of a slot might have been a 5 reel machine with 5 win lines, but now they’re so diverse.

Some are so immensely innovative that it’s almost beyond comprehension, and this draws in players who are looking for only the latest inventions.

Slot Bonuses

Bonuses help you play slots without spending your cash balance. What’s more, they hold value, meaning you can use them to win real money. It also means bigger bonuses give you better chances of winning.

When it comes to choosing slot sites, however, the amount of bonuses isn’t the most essential thing. Instead, it’s what value a bonus gives you that matters the most. Precisely, you want a reward you can use on your favourite slots. Then it should also allow you to withdraw your winnings hassle-free as in every fast paying UK casino.

Good Payment Methods and Policies

Deposits and withdrawal processes have made lots of people lose faith in online casinos. There never seems to be an operator that lets you cash out your wins smoothly. However, that’s not truly the case.

Some operators will let you cash out instantly, and some have it so refined that the money is in your account as soon as you hit withdraw.

This is truly one of the shining beacons of a UK Slot site, but be wary of other things.

Before you’ve even gotten to a withdrawal you should have checked that the site has a sufficient SSL security certificate to keep your details safe, and a wide variety of known and reputable payment operators.

Also, look out for casinos that may charge a fee when you’re looking to deposit or withdraw.

Some websites will charge a fee upon deposit, and some may charge a fee when you withdraw.

Some sites will let you withdraw for no added cost on your first withdrawal of the day, but any others after that may be chargeable.

Best Slot Sites the UK has to offer

best online slots uk 2022 - jackpot.comSimilar to many websites, there are good and bad operators. The best slot sites in the UK accept payments from well-known companies. That means the deposit process is always smooth and safe. In contrast, they let you withdraw your money fast and smoothly.

When it comes to fees and limits, the best slot sites work to seamlessly improve players’ experiences. That means they have little or no deposit and withdrawal fees. Again, they allow withdrawals of small and enormous amounts for the convenience of their customers.

Reliable Customer Service

No matter how well-managed a casino is, there comes a time when you need assistance. You might have issues with payments, or a game might have experienced technical hiccups. A great casino will come to your rescue 100% of the time. Most of them offer support through these channels: live chatbots, email, and phone support.

Live chat is always a preferred contact method because it eliminates the need for lengthy hold times on the phone. Some of the best online slot sites are known for more than just their game selection.

Both older and new online slot sites will have a team of professionals ready and waiting to help.

In fact, it’s a bit of a red flag if the customer service isn’t on point. If you’re signed up to a casino with a team that is hard to reach, then perhaps they’re intentionally trying to avoid contact with players.

If this sounds like you, then reevaluate your choices and switch to one of the best UK slot sites with the best customer service.

Slot Sites Rated and Reviewed by Our Experts

You can find recommendations for online slot sites on hundreds of websites. But here’s the problem. Can you trust these suggestions? How can you prove that a top-rated company offers quality customer support?

Best Online Slots Reviews

Take a look at the reviewer. A slot site review is as good as the person reviewing it. At Fruity Slots, our reviewers are diehard casino streaming players who’ve been playing slots for over a decade. They even run a couple of streaming channels on YouTube and Twitch.

That means we are not people who place ratings on online slot sites just because they look beautiful. We don’t say a casino is impressive because it claims to offer one-day withdrawals. We put casinos to the test, something you can witness on our streaming channel.

At Fruity Slots we bring you daily content with the latest and greatest when it comes to Online Slots, Casino Reviews, and more.

You might see a news article about the latest changes in the casino industry, or an interview with a provider behind your favourite slot games.

Content never sleeps at Fruity Slots, so keep an eye out on our website for the latest news on the best slots, new slots websites, and more.

Best Online Slot Games to Win

The best online slot games to win depends on what you’re looking for, and if you’re looking for a nice top-up or to change your life completely!

Make no mistakes, slots shouldn’t be used as a source of funds, but there are a few games that could change the lives of a lucky few.

If you’re looking for big hits, then you’ll want to pick a high-volatility game. High volatility games are named so because they’re ‘all or nothing’ in a sense. You’ll find that you’ll win less often with these games, but when you do it could be massive.

If you’re looking for something a little more reliable, then low volatility slots could be your best shout. Low volatility slots have a lower maximum win cap, so even at its best it might not be ‘huge’. Low volatility slots bonus more often, and the payouts are a little more consistent compared to their high volatility counterparts.

Another option is Jackpot Slots. Jackpot Slots dangle huge jackpots in your face like a carrot, but you’ll need to be extremely lucky to see it. Various jackpot mechanics exist, and the latest to take the gaming industry by storm is Relax Gaming’s Dream Drop jackpots.

Dream Drop Jackpot games have a maximum prize that can reach over £/€1,000,000, and it’s already been claimed a few times by some extremely lucky winners. Jackpot slots might favour players who play at higher stakes, but it’s not impossible, and there’s still a chance of landing one of the smaller jackpot prizes.

List of the Latest New Online Slots

We’re constantly up to date with the latest in the slot industry. You can check out our New and Upcoming sections for newly released games, and games releasing soon.

Here are a few of our favourite new slots, as well as some that we’re really looking forward to!

The latest new online slots are changing faster than ever before, with hundreds of new games being released every single day.

It’s hard to pick your favourite when there are so many good ones, but there are certainly some that shine. Nolimit City has made a name for themselves with their innovative and sometimes controversial games, including Relax Gaming and their studio partners that continue to impress with high volatility games and Dream Drop Jackpot slots.

Compared to a few years ago, the number and nature of games are drastically different. Who knows what they’ll release next?

Best Online Slot Games UK

The UK is a slightly different market compared to elsewhere. In recent years, changes have been made in the interest of player protection, so you might have seen a few features disappear. Bonus Buys are no longer an option for UK players, and this could render some games a little bit obsolete depending on the context.

Games with super bonuses might be locked away completely, and even if they aren’t they may be unviable compared to slots catered towards a UK market.

So with this in mind, what are the best slot games in the UK?

Thankfully, there’s plenty in the way of games that are more than viable for UK players. Providers like Play’n GO do not have bonus buy features in their slots, so their games are the same wherever they’re released…well, aside from RTP.

The Best Online Slot Games in the UK are slots with high-potential bonus rounds that aren’t locked by bonus buys, or Jackpot slots because your chance is as good as anyone elses!

Our site has hundreds of comprehensive slot reviews, so why not check out our site to find your next favourite?

Online slot sites bonuses & offers

If we are comparing slot sites with the best bonuses, we claim their offers and use them. Our reviews come later on after we have done extensive testing to confirm which operators are deserving of top ratings.

For clarity, our top-rated casinos must also meet the criteria we outlined above. That means they need a license from the UKGC, decent game variety, attractive bonuses, and reliable customer support teams.

Our Team of Slot Geeks

There are for sure no bigger slot geeks out there than us. Here’s one example of Jamie enjoying himself with different slots, played at different slot sites!

Which Slot Sites have the Best Games?

As mentioned, everyone wants to play the best slots. But how do you know which games these are? Are these games you can find with ease? How do you identify them? Generally speaking, this is what experts mean when they talk about the best slots:

  • High Return to Player (RTP) rates
  • Top-notch graphics and sound
  • Plenty of bonus features
  • Engaging storylines
  • Random or progressive Jackpots

It doesn’t matter what taste you have when it comes to slots. You could be a fan of TV show-themed games. Or you might have a taste for ancient Egypt slots. The best slot sites offer games with the features mentioned above.

Perhaps most important of all is the win potential. Many search for a slot purely with high potential. Little else matters to Jackpot chasers, and it’s interesting to see how slots are evolving as a result of player preference.

Are the Best Slots Online Volatile?

High volatility slots are named so because they’re more turbulent. With these kinds of slots, the winning potential is massive, but you’ll also run a higher risk of winning little to nothing.

The volatility of slots has been steadily increasing over recent years which suggests a growing demand for slots with higher than-ever-before winning capabilities, but what other alternatives are there?

Casinos are almost like time capsules with catalogues of slots from a bygone era. Your favourite casinos will still host firm favourites from years ago, and they’re probably likely to be less volatile.

Less volatile means more dependable in some cases, though they’re probably not as exciting. The best Low Volatility slots often bonus more, but the amount you win isn’t likely to be huge.

Good casino sites will have a mix of Low and High-Volatility slots that cater to a wide demographic of players.

What are the Best Online Slots for Real Money?

You’ll find plenty of demo slot sites, but where do you go if you’re looking for the best online slots to play with real money?

Fruity Slots keep a close eye on the best online slots site before we conduct a full review. In our reviews, we’ll take into account the best online slots in the UK, Live Casino games, High and Low Volatility slots, and more, such as Customer Service, Interface, and more.

We only promote the best online casino slots, so you certainly won’t find any unregulated sites with a poor selection of games here.

Are UK Slots Different From Those In Other Countries?

UK Slots and slots from other countries might look identical, but there are a few things behind the scenes that make them different.

Here are some of the ways in which UK slots might differ from those in other jurisdictions

  • RTP – The RTP might differ depending on the country that you’re from. The best slots online in the UK have great RTP values, but they might not be as good as those in other countries. However, in countries like Germany, the RTP is generally much lower because of laws that have forced casinos to lower it in order to remain profitable.
  • Bonus Buy – If you’re in the UK, you might remember a time when bonus buys were available. This is no longer the case now that Bonus Buys are no longer legal on online slots websites in the UK.
  • Quickspin – Casino slots in the UK won’t have the ability to quickspin any longer due to the latest UK law. The same game in another country may come with quickspin enabled, but this feature will no longer be offered to UK players.

Best UK Slots 2023

With that in mind, below is an overview of slot sites known for their great variety of slots.

  1. Grand Ivy Casino: Best known for its slot bonuses, this casino provides games by companies like NetEnt, Games Global, Nyx, Thunderkick, and Quickspin. Grand Ivy Casino has been around since 2016 and has a solid reputation when it comes to customer service.
  2. Casimba Casino: Famous for its wide selection of games. Here you will find slots from over forty software providers on this website. It also has a decent welcome package and is a top-rated website.
  3. PlayOJO: Best known for no-wager bonuses, PlayOJO is a casino worth the top rating it receives. Not only does it give out no-wager loyalty bonuses for life, but it also features over 1,000 slots. It also provides daily Jackpots and competitions that culminate in thousands of pounds worth of rewards.
  4. Mr. Play Casino: Well-known for its many Jackpot slots, Mr. Play is an overall fantastic slot site. First off, it features more than 1,000 games from over 50 providers. It has a variety of bonuses and pays within 24 hours for e-wallets.
  5. Queen Play Casino: Established in 2020, Queen Play is the ideal slot site for casinos launched this year. It has more than 500 slots and supports over 20 banking options, including PayPal. It’s not very popular, but its reputation is increasing.

Don’t Forget about Game Providers & Online Slots

Game providers are the companies that supply slots to your favourite online casinos. That’s why they matter so much when making a decision about which new slot sites in the UK to join. If a developer is known for offering sports-themed slots and that’s what you like, then you need to find a casino with games from that provider.

Below is an outline of the most popular slot game providers and what they are famous for.

Nolimit City

Nolimit City is a Stockholm-based provider with offices in Malta and India.

Nolimit City has gained infamy as a provider willing to push the boundaries in just about every aspect of their slots. Themes, gameplay, features and potential often far outperform that of other providers.

Pragmatic Play

Pragmatic Play is as popular as any other Provider, with a huge catalogue of Slot and Live Casino games.

No matter where you are, you’re likely to find a hearty selection of Pragmatic Play titles. These happen to be favourites for fans everywhere, and for good reason.


Established in 1999, Playtech is best known for providing exclusive licenses to casinos. Precisely, it has all the games players like and so can offer both slots and card games. That said, Playtech is also vested in branded slots, particularly games based on the Marvel universe. Some of the best games by this provider are Ugga Bugga, Desert Treasure, A Night Out, and Goblin’s Cave.


Established in 1996, NetEnt is responsible for some of the most well-known online slots in the UK. These are Twin Spin, Gonzo’s Quest, Starburst, and Mega Fortunes. The Swedish brand has a robust reputation for providing beautiful, innovative, and high-paying games. So, you might want to try some of their creations.

Games Global

Launched in 1994, Games Global, formerly known as Microgaming, is the oldest online slot provider. It’s also the biggest supplier of slots, having created over 1,000 slots. The company is known for being a trendsetter and regularly competes with NetEnt for the top spot. For the uninitiated, Games Global is the developer behind Meg Moolah, a progressive Jackpot slot that’s globally famous for paying millions to winners.


Most people are surprised to learn that Betsoft launched way back in 1999. That’s because, unlike NetEnt, Games Global, and Playtech, it’s not talked about so much. Lately, however, Betsoft is proving their worth the attention thanks to their slew of 3D slots like Mad Scientists, Las Vegas, and the Wild West.

Big Time Gaming (BGT)

Australia-based BGT is relatively new, launching in 2011, but they’ve been trending since they started a new genre of slots a few years ago. Known as Megaways, these games have up to 117,649 ways to win. They feature 5-7 reels and thus give you a chance to maximize your wins much better than standard slots.

Generous Bonuses on the Best Slot Sites

Some of the casinos we’ve mentioned in this guide are pretty generous with bonuses. Take a look at some of the offers you can expect from them.

No Deposit Bonuses

These are some of the easiest bonuses to claim. All you need to do is register an account at a casino. After this, you can claim free spins or £20 to use on a specific slot. For clarity, you can use no deposit bonuses to win real money. But beware, they come with terms and conditions.

No deposit bonuses generally only offer Free Spins, and sometimes they’re quite limited in what they can do. 10 Free Spins might not stretch far, and you’d need to be really lucky to see a big return from a bonus like this.

This is why many prefer deposit bonuses.

First Deposit Bonuses

You receive these bonuses once you’ve created an account and made your first deposit. Some casinos extend the offer to your second, third, and fourth deposit. The best part of it is that casinos could also throw in free spins on select games. Welcome bonuses range from a minimum of £10 up to £2,000.

Deposit bonuses can essentially double your balance, giving you a real chance to make a substantial cashout.

However, the terms for these are sometimes strict and you’ll need a lot of know-how and a fair amount of luck too.

Reload Bonus

Reload bonuses are given out to reward loyalty. The exact offers vary from one casino to another. For example, one platform could give you 50% bonuses every time you deposit. A different company could limit its reward to 30% for the first deposit of the month alone. Nonetheless, you get a bonus for being a loyal customer.

Loyalty Programs

Loyalty programs are strategic offers you receive every time you play slots at a casino. These could be points you can later redeem, or they could be cash back for your losses. They are meant to keep you loyal at a casino.

VIP Programs

These programs target the big spenders at casinos. That’s why it’s so difficult to qualify if you spend less than £500 on casino games. Some casinos actually make them invite-only programs to minimize the number of members. But most sites these days have VIP programs open to all casino members.

Of course, you need to spend hundreds or thousands of pounds on qualifying and continue to play their games regularly. Otherwise, you could lose your place at these prestigious clubs. In case you are wondering, the rewards for being a VIP player are bigger bonuses, a personal manager, free games, and fast withdrawals.

Greater Jackpots in Online Slots UK

Nearly all game providers that develop jackpots offer their games to UK slot sites. That means you can play the famous Mega Moolah and Mega Fortune, or slots that are not necessarily renowned games.

There are several types of progressive jackpots in the UK. There’s the standalone game. That means one slot with a jackpot that is not linked to any other game or casino. You must play that slot if you want to win its grand prize.

Then there’s the in-house jackpot. It could be linked to multiple games, but it’s limited to one casino. Most of these pots have daily, weekly, and monthly payouts.

The last type is what people know about the most: wide-area jackpot. This game might come from one provider—say Games Global’s Mega Moolah, but it can be played in all casinos that offer this game.

Better Payout Rates Considered

As mentioned, one of the most vital things to consider when choosing a slot site is its payout rates. In many cases, you need to check the slots and discover their average RTP rates. This information is publicly available, so it’s simple to find it.

While you check slots’ payout rates, also find information about how frequently they payout. Slots tend to be different. Some payout often but in small amounts. These are excellent games for beginners and people with small budgets.

On the flip side, some slot payout in average rates. That means they are neither too generous nor too mean. The final end of the spectrum features highly volatile games. This is where Megaways slots fall into. They payout scarcely but in exceedingly vast amounts.

New Slot Sites UK

As the name suggests, new slot sites in the UK are newcomers to the online casino industry. Most of them have been in business for a few months or a couple of years. But here’s what most people don’t know about them. These companies open up to provide solutions that are lacking in the industry.

For example, they might feature games from underappreciated software providers. Or they come up with innovative bonus systems. A case in point is PlayOJO. It’s been around for a while. But when it launched, very few operators had the idea of providing wager-free bonuses for life.

Why Choose a New Slot Site?

As mentioned, new casino sites launch with a mission to solve players’ pain points. Some want to fix the customer service problem many casinos seem to have. Others open doors to offer a solution to people who can’t find a casino that processes withdrawals quickly.

Choosing the best slots websites

The primary reason you want to choose a new slot site is that it might have solutions for problems that other casinos refuse to solve. It could be a better version of your favourite website—a platform that not only provides your favourite slots, but also offers overall quality services. Of course, not all new casinos are reliable. Take time to compare several companies and select the one that’s most suitable for you.

If you’re still stuck, then feel free to check out our reviews.

We’ve reviewed hundreds of Slot Sites in the past, so we like to think we know what we’re talking about in this regard.

Our Criteria

There are a few things that we look out for when we review a casino.

  • Licence and Regulation – All of the casinos that we review must be licenced and regulated by the UKGC (UK Gambling Comission), or another authority depending on the jurisdiction of the casino.
  • Security and Safety – We won’t touch a casino that does not do an excellent job of protecting our details, and neither should you. You won’t find a review on our site for a casino without SSL security. They simply cannot be trusted if they have not taken these steps to protect players
  • Payment Methods – Casinos must accept globally recognized payment providers, and they must be reasonable in their time frames for a withdrawal.
  • Games and Software Providers – The best online slot sites in the UK must have a wide variety of games from recognizable game studios. You might have seen casino sites without games that you recognize, and if you don’t recognize anything then you should probably give it a miss.
  • A Good Welcome Bonus – The best casinos must back themselves with something to offer players. If we’re not convinced about the offer, then we won’t recommend the casino. After all, why choose a bad bonus when there are so many convincing ones elsewhere?
  • Customer Support – Customer support is an absolute must. A casino should not hide behind lengthy and complicated contact methods. They should be clear and concise with thorough FAQ sections, clear contact methods, and preferably live chat!

Best Slot Sites FAQ

Many slot sites claim to be the best, but there’s a lot of factors in play when determining which top slot sites deserve the title.

Here are some of the most frequently asked questions about the best online slot sites.

  • Are New Slot Sites Generally the Best?

    A new site might come across as the best because of their efforts in making their new slot site the most appealing to potential customers.

    Offers might be better than you’ve seen elsewhere, and the site might look and feel more attractive and more responsive than some older sites.

    As always, the first thing to look for should be certification. New slot sites should be fully licenced to operate in Great Britain with a UKGC licence.

    Next, you should research the offers available and check to see if they’re as good as they claim to be. Sometimes wagering requirements are a lot higher than elsewhere, so the offer might not be as good as it first seems

  • What Are The Best Slot Sites for Winning?

    Believe it or not, many casinos are made equal, meaning you have an equal chance at just about any online slots site.

    However, there is an exception to the rule when it comes to game RTP. Even the best slots websites may have a lower RTP variant of a slot than another site, but what does that mean for you?

    Some say it makes a big difference, but to the average player it won’t matter much. RTP is calculated over billions of spins, so the likelihood of it playing much differently to a higher RTP variant across a short time frame is quite slim.

  • What Are The Best Slot Sites of 2023?

    There are certainly a few contenders for the best slot site in 2023, but many are very similar in how they function and what they offer.

    The best slot site for one person might not suit another, so make sure you’re clear in what you want from a casino, and that the casino that you’re signing up for has what you’re looking for.

    Players will want to look for the best bonuses, a wide variety of slots, live casino games and more.

  • Do Top Slots have the best RTP?

    High RTP is important, but it’s not everything. Some of the best slots around have a lower RTP percentage than others, yet they’re still regarded as a fan favourite because its huge potential.

    Remember that RTP and win potential aren’t the same. Not all slots were created equal, just like casinos aren’t, and some are certainly better than others even with a lower RTP value

  • Why might UK Slots have a lower RTP?

    The UK might have a lower RTP than slots in other countries due to UK laws. In order to remain profitable, casinos may need to lower the RTP.

    Compliance is vital to slot sites in theUK, but the laws and regulations may require them to make changes to their games from time to time.

  • Are Megaways Slots the Best?

    The popularity of a Megaways slot speaks for itself when you consider how popular they still are today, despite their release a few years ago.

    Big Time Gaming created the Megaways mechanic, and fast forward a few years and it seems like everyone is trying to make one. Many slot providers obtain the licence for a Megaways slot in the hopes that they’ll create the next big thing, but does the overwhelming popularity of a Megaways slot mean it’s the best?

    It’s all down to personal taste at the end of the day, but we must say, we’re somewhat under the Megaways spell ourselves.

    Megaways slots have huge divisibility, lots of potential and high RTP values. These are just a couple of the reasons why they’re so popular.
