The Top 5 Casino Sites in the UK: A Closer Look

You may think that English casino sites are ‘much of a muchness’, but that’s really not true. Some online casinos are perfectly palatial, combining a wealth of gaming options with bonuses that are highly beneficial. Others have crappy software, are a nightmare to navigate and their bonuses are complete bobbins.

We of course want to point you in the direction of the former and steer you well clear of the latter. For starters, here is a list of what we consider to be the top 5 best casino sites UK.

1. Genesis Casino (100% up to £100 Bonus + 300 Bonus Spins!)

Fully licensed in the UK, the Genesis Casino is something of a ground-breaker in terms of design and playing options. This smooth site just looks the business on both desktops/laptops and all manner of mobile devices. It has countless fantastic games too from leading providers such as NetEnt, Play’n GO and Quickspin.

Genesis Casino

There’s a vibrant live casino as well and Genesis Casino is one of the few best casino sites UK where you can play craps with a live croupier. Significant deals too, espeically for newbies with a 100 percent matched bonus up to £100 and 300 bonus spins on the casino realm’s number one slotting title, Starbust. A great place to start off your online casino career!

What we like:

  • Nice welcome package
  • Great selection of the very best games around
  • Perfectly secure – industry-standard encryption used
  • Very mobile friendly

What we don’t:

  • The design of the site will not appeal to all

18+ Full T&C’s Apply. New players Only. £10 min deposit. £5 max bet using bonus. 40x wagering applies. Bonus valid for 14 days. 30 Spins will be credited instantly upon qualifying deposit + then 30 per day for 9 days on Starburst. Free Spins valid for 72 hours from credit. Max Free Spins winnings £100. Ewallets excluded.

2. Sloty Casino (100% up to £100 & 300 Bonus Spins!)

If there is one UK casino site that we like a lot-y, then it has to be Sloty! This site promises UK-based casino players the best in casino game action, and unlike many of its contemporaries it actually delivers! You’ll find all the best games from gaming experts such as Evolution, Microgaming and Red Tiger, plus a huge number of convenient payment options from Visa to Boku and many more.

Slotty Casino

This site of course has a promo offer for new players, and it’s a good one as it’s a matched bonus up to 100 quiddlies plus a massive total of 300 bonus spins. This site also features Pragmatic Play’s ‘Drop & Win’ promo where you could win big if you play any of the nominated Pragmatic Play slots available at the site.

What we like:

  • Start off with an attractive welcome bonus
  • Excellent options when it comes to casino games
  • No problem ever finding a live casino table
  • Looks good and works well on tablets

What we don’t:

  • The video poker titles are ancient

18+ Full T&C’s Apply. New players Only. £10 min deposit. £5 max bet using bonus. 40x wagering applies. Bonus valid for 14 days. 30 Spins will be credited instantly upon qualifying deposit + then 30 per day for 9 days on Starburst. Free Spins valid for 72 hours from credit. Max Free Spins winnings £100. Ewallets excluded.

3. Grosvenor Casino (Deposit £20, Play with £50)

Head to the centre of your nearest city and the chances are you may stumble upon a Grosvenor Casino. This company – owned by the Rank Group – are the leading providers of real world casinos in the UK today … and their efforts extend online too. You also get a feeling of ‘class’ when you play online at Grosvenor Casino, as the design of the site reflects perhaps how an online casino ought to be.

Grosvenor Casino

The welcome bonus at Grosvenor Casino is not exactly gargantuan, but it has one of the best wagering conditions you’ll find anywhere – only five times the value of your deposit. It also comes in three parts – £20 to spend on eligible casino games, £10 to spend on classic slots or at the site’s live casino, and £20 to spend at your nearest real-world Grosvenor Casino venue.

What we like:

  • Backed by a very reputable company
  • Outstanding wagering – a 5x rollover requirement
  • Site looks classy
  • Poker and Sports just a click away

What we don’t:

  • You have to visit a real casino to use part of your bonus
Offers available on 1st deposit only. (Max reward £50 bonus, 5x wagering). Some games have different wagering contributions. Some games exclude bonus play. T&Cs apply.

4. 888Casino (Play with £88 Free No Deposit Needed)

When it comes to wagering online in the Uk, you’d be hard-pressed to find something that 888 doesn’t do. if you’ve been around Safe Betting Sites awhile you will know all about the positive vibes we get from 888Sport. 888 also runs popular poker and bingo sites, and even a long-running ‘females only’ slots and bingo site called 888Ladies.

888 Casino

888 of course do a casino too and – also of course – it’s called 888Casino. The site has slots, casino games, jackpot games and more, including all the Megaways titles available on licence from developers Big Time Gaming. It is also one of the few casinos around that offers a no deposit bonus, and it’s a bit of a stonker too, set at £88. Before you get too excited, wins from one of the best no deposit casino sites bonus are capped at a tenner, although there’s a welcome bonus up to £100 too.

What we like:

  • The biggest no deposit casino bonus available anywhere
  • 888 are true gambling experts
  • One of the fairest deposit bonuses you’ll find anywhere
  • Outstanding ‘apps’ for phones and tablets

What we don’t:

  • No deposit bonus winnings capped at £10
  • Design of the site hasn’t changed for yonks!
New players only • Claim within 48 hrs • 14 day expiry • FreePlay (FP) wins credited as bonus & capped at £10, excl. JP wins • Valid for selected games • Bonus wins capped at £500, excl. JP wins • 50x wagering – req. vary by game • Bonus expires in 90 days • Withdrawal restrictions.

5. Karamba Casino (Up to 100 Spins + Up to £50 Bonus)

The online wagering world has several mascots, and one of the most popular is Karamba Casino’s turquoise and purple parrot. This nameless avian (although we are willing to hazard a guess that his name might be ‘Karamba’) has been flitting happily around the internet since Karamba Casino first appeared online, back in 2005.

Karamba Casino

The kolourful Karamba site has plenty of the latest and greatest games, including the best slots, table games and jackpot games. There’s also a fabulous live casino too where you can grab a bonus of £50 that’s for live casino play only.

The main bonus though offered by that pesky parrot is 100 bonus spins on top of a maximum £50 matched bonus. For your full bonus bonanza (including all those bonus spins) you need to make three qualifying deposits of £50, £20 and £20 respectively. Wagering is a ‘fair and square’ 35 times over.

What we like:

  • Entertaining-looking site with a cheerful mascot
  • Bonus is standard, but it’s a good one
  • Live casino options are plentiful
  • Site has been in operation for 15+ years

What we don’t:

  • Some menus don’t seem to work properly
  • The parrot gets everywhere – can become annoying
Terms and Conditions apply. New players only. 18+. Min deposit £10. Wagering requirement apply 35x. Offer valid for 72hr. 100 spins includes 3 deposit. See full terms.

How we Rate the Best English Casino Sites

Our casino experts have been spinning slots and chucking in their casino chips for well over a decade now. When it comes to deciding which sites are worthy of your custom and which should be avoided like Piers Morgan avoiding a vegan sausage roll we take a number of factors into consideration, as follows:

A Decent Range of Decent Games

Virtually every online casino now will boast about having “100s of Games!” but in many cases when visiting a site you just find a couple of hundred poor-quality online siots. When we visit an online casino we want to see a host of great games from the industry’s best – names such as NetEnt, Microgaming and Playtech. A fantastic selection of the best slots plus table games such as blackjack and roulette and a live casino are all “must haves” as far as we are concerned. Other games – video poker, baccarat, sic bo, casino poker to name but four – are nice to see too, and even less ‘popular’ options such as virtual sports games, bingo and scratch cards are welcome options as well.

Quality, we feel, is more important than quantity when it comes to casino games, and the best online casinos are those with a quantity of quality titles!

Bonuses That Actually Have Benefits

Just like UK betting sites, UKGC-licensed casinos will offer new customers bonuses if they sign up, make a deposit and start playing. Hidden behind many of these bonuses though are fiendish wagering conditions that render bonuses that look amazing on the surface as worthless as a pre-2016 five pound note.

We’ll dissect what makes a decent bonus later on, but when we look at an online casino we do take their bonus offerings into account, and that includes both new customer bonues and promo codes for established users of the site.

Help When You Need It

There was a time when companies took customer support very seriously, but that attitude seems to have been banished to the past along with dial-up broadband, fidget spinners and Friends Reunited. Calling ‘customer support’ now entails a 20-minute wait before being put through to a call centre in Mumbai to speak to someone called ‘Marjorie’ who hasn’t the foggiest notion of what you’re talking about.

Some of the top casino sites UK though do take a professional approach to their customer support options. We like sites to have a dedicated phone line plus live chat too. ‘Just’ an email address does not cut the mustard as far as we are concerned.

Options When It Comes to Deposits and Withdrawals

The most common option used by online casinos for both deposits and withdrawals is a debit card (remember that the use of credit cards at new casino sites UK was banned by the UKGC in 2020), which is handy as most people who have bank accounts in the UK will have a Visa debit card for card and contactless payments and ATM withdrawals. Not everyone though is happy to use their debit card online, so we give a thumbs up to casinos that accept as many alternatives as possible.

We like to see options for eWallets (PayPal, Skrill, Neteller), eVouchers (Paysafecard), mobile payments (Boku) and even cryptocurrencies (Bitcoin, Litecoin) if possible.

Bonuses Available at the Best Casino Sites

Casino bonuses are a mystery to many. The only thing about bonuses that everyone is 100 percent sure about is that every online casino has one! However, there are many different types and all come with dreaded terms and conditions that can reduce your bonus cash to zlich quicker than you can say ‘Gonzo’s Quest Megaways’.

When it comes to bonuses you’ve got friends at Safe Betting Sites. We’re going to tell you all you need to know about the different kinds of bonuses available to UK players; how to understand them and how to work your way through those terms and conditions. You may think that all UK casino bonuses are scams, but that’s not true at all. You can easily end up in the black thanks to a casino bonus, and if you digest our guide fully we’ll give you the best chance of doing just that.

Understanding Terms and Conditions

Just like every Pot Noodle comes with a sachet of weird-tasting sauce, every online UK casino bonus come with terms and conditions. When you grab your first casino bonus, those T&Cs look indecipherable. Once you’ve grabbed a handful, you become something of an old hand. Safe Betting Sites is here to guide you through the minefield of casino bonus T&Cs, and if you want to thank us for our efforts why not send us a Pot Noodle or even better, don’t!

Here is a speedy round-up of the most common factors that you’ll find enclosed within casino bonus T&Cs:

Wagering Requirement

This is the minimum amount you need to wager (of your own cash) before you can cash out your bonus and any winnings you make from it. The welcome bonus at Genesis Casino has wagering requirements of 40x (deposit and bonus). If you were to make a £50 deposit then you’d receive a £50 bonus. Add these together and multiple by 40 and you get £4,000. This means you have to wager £4,000 before you can cash out your bonus and winnings.

This could be achieved by 4,000 £1 spins of a slot at the site, as an example. Note that this is the amount you need to wager and not spend. You are not going to lose on every one of those 4,000 spins, and indeed you could end up with more money that what you started with!

Minimum Deposit

The minimum amount you need to deposit in order to qualify for a bonus. The welcome bonus offer at Sloty Casino for example has a minimum deposit amount of £10, which is a common ‘threshold’. If you make an initial deposit of £5 at Sloty Casino, then you will not receive a bonus, and you will now be unable to claim one.

Minimum/Maximum Stake

It would be nice if you could complete your wagering requirments as quickly as possible. For example, the welcome bonus at Casino has wagering of 35x bonus. If you were to make a £20 deposit, then that’s total wagering of £700. You could complete your wagering with seven £100 hands of blackjack (if you don’t mind plenty of ‘squeaky bum’ moments). Even the top 10 casino sites don’t though want you to complete your wagering quickly, so they put maximum stake requirements in those T&Cs.

In the example of Casino, the maximum stake is £4 per spin/hand. This means that if you stake £4 or over – even for just one spin or hand – then your bonus is forfeited. Minimum stakes in T&Cs are less common (they are usually tied to high roller bonuses), but you need to check the offer’s T&Cs to make sure your wagering is 100 percent legitimate.

Eligible Games

In the good old days, even before Brexit and COVID-19, you were free to use ANY casino game to meet your wagering requirements. That, sadly, is no longer the case. While slots largely remain as ‘okay’, casino games are restricted or banned altogether. If they are restricted, the T&Cs will say that ‘only 10% of any blackjack stake contributes towards wagering’. This means that of a £1 bet on a hand of blackjack, only £0.10 will be removed from your wagering requirements once it has been played.

The welcome bonus at Karamba Casino, for example, has a large list of games that only contribute 50% and 10%, and some titles such as blackjack, roulette and video poker do not contribute at all. Many sites restrict slots too, so again make sure you fully check the T&Cs with any bonus offer. Online casinos are not known for their forgiveness should you make a casino cock-up.

Eligible Payment Methods

It’s become a common theme over the past couple of years for online casinos to refuse to pay bonuses for deposits via eWallets such as PayPal, Skrill and Neteller. This is largely to stop people from claiming a welcome bonus multiple times, as it is a lot easier to open an eWallet account than a bank account. Most bonuses now can only be claimed when making a deposit via a debit card or ApplePay.

Time Limits

You can’t take months to meet wagering requirements. You may find that your bonus will disappear from your account if you do not meet your wagering expectations within seven days. For a bonus spins promo code, it might be as short a time as three days. Again, check the offer’s full T&Cs to make sure you’re unlikely to encounter a nasty surprise once those wagering expectations are met.

Types of Bonuses Available at New Casino Sites UK

There are many different types of bonuses available the top casino sites, and here we are going to walk you through what you need to do in order to claim each type, and work through those deadly wagering expectations.

Matched Deposit Bonus

The most common type of bonus offered by online casinos is a matched deposit bonus. For a ‘100% Deposit Bonus’ the value of your first deposit at a casino site will be matched by the same amount in bonus cash. A ‘200% Deposit Bonus’ will double the value of your deposit in terms of bonus money, and a ‘50% Deposit Bonus’ will halve it, and so on. All deposit bonuses come with wagering requirements.

Here is what happens when you claim the 100% deposit bonus at Sloty Casino, which has wagering expectations of 40x (deposit and bonus), minimum deposit £10, debit cards only, max stake £5, slots only.

  • You sign up for a new account at Sloty Casino
  • You make a deposit of £20 using your Visa Debit Card
  • You are awarded £20 in bonus money
  • The wagering expectations are 40x (deposit and bonus), which is £1,600
  • You play 1,600 spins on NetEnt’s Starburst, which you have checked to see is an eligible slot
  • At the end of your 1,600 spins, you have £28.50 remaining
  • Your £28.50 is free for you to withdraw as you have completed the T&Cs

Bonus Spins

Bonus spins are spins on a slot that you do not have to pay for. Some sites offer bonus spins on top of a deposit bonus, and other sites just offer bonus spins on their own. To qualify for bonus spins, you usually just have to make a minimum deposit at the casino offering the deal. The best bonus spins offers come with zero wagering expectations, but it is more common to find a bonus spins promotion that does come with wagering. Bonus spins deals are also usually tied to a small range of slots, or just a single online slots game.

Here is how to claim the 300 bonus spins deal at Genesis Casino, which has a minimum deposit of £10 and wagering expectations of 40 times your bonus spins winnings (max total win £100), debit cards and Apple Pay only.

  • Sign up for a new account at Genesis Casino
  • Make a deposit of £10 using Apple Pay
  • You are awarded 300 bonus spins over ten days on Starburst
  • You play your spins and you end up with £12
  • Your wagering expectations are now £480
  • You play 480 £1 spins, continuing with Starburst (although you could use other slots)
  • You now have £33, nice!
  • That £33 can be withdrawn, or you can use it to play other slots and games at the site

No Deposit Casino Bonus

Like footballers without any tattoos, no deposit casino bonuses were once common but now no deposit casino sites are rarely seen. As the name suggests, you do not have to make a deposit when claiming a ‘no deposit bonus’ – you just have to sign up for a new customer account.

Not only are no deposit casino bonuses rare, they are usually low in value and come with tight wagering requirements. Here is how to claim the £88 no deposit casino bonus that is available at the 888Casino.

  • You sign up for a new account at the 888Casino
  • You receive £88 in bonuses, no deposit!
  • The wagering expectations are 50x, which is £440
  • You decide to play blackjack at £0.50 per hand
  • After twenty minutes you hit a bad losing streak and your bonus money is gone
  • Tough cookies!

Reload Bonus

A reload bonus is virtually identical to a first deposit except that it is not tied to your initial deposit at an online casino. You usually can claim a reload bonus at any time, although you will probably be restricted in that you may only claim a reload bonus once per week. Some of the better online casinos though have daily reload bonuses.

Here is how to claim the Wicked Wednesday reload bonus (no eWallets) at the Yeti Casino, available once per week only. This bonus could be a deposit bonus or bonus spins, but the wagering is the same for each – 40x the bonus.

  • You have been a member at Yeti Casino for a few weeks
  • You decide to claim the weekly reload bonus, so you deposit £20 via a debit card
  • On Wednesday you are awarded a reload bonus of £10 (50% of £20)
  • Your wagering expectations are £400
  • You play 800 spins of Fluffy Favourites at £0.50 per spin
  • At the end of your 800 spins, you have £14!
  • Your ‘bonus’ money is moved to your real money account for you to spend or withdraw

Cashback Bonus

Cashback bonuses offer you money back on your weekly losses at the site that is offering the cashback deal. The best cashback deals pay you your money back as cash, but most of them pay your cashback as bonus money that usually comes with the same wagering expectations as any deposit bonuses the site offers.

Some cashback deals are paid automatically but with others you have to contact the casino either via email or live chat in order to claim any cashback that you are due. Here is how to claim the 10 percent weekly cashback offer available at the All British Casino, as cash with no wagering.

  • You spend a week playing slots and roulette at the All British Casino
  • At the end of the week you have £50 less than what you started with
  • You contact support at The All British Casino to ask for your cashback
  • You are awarded £5 (10% of £50) in real money
  • You are now free to withdraw that £5 or continue to wager with it at the site

High Roller Bonus

High Roller Bonuses are not generally advertised as available at online casinos. If you don’t mind splashing the cash (and do so responsibly) then you can contact your favourite online casino to see if they will offer you a high roller bonus. The terms of high roller bonuses are usually decent, although the minimum deposit amount is, as you might expect, quit high.

Here we will show you how to claim a high roller bonus at LeoVegas. Please be aware that this scenario is entirely hypothetical, as the award of a high roller bonus at LeoVegas depends upon your previous history at the site. If you have no history of making substantial wagers at LeoVegas, then it is unlikely that they will offer you a high roller bonus.

  • You contact support at LeoVegas asking for a 100% bonus for a £500 deposit
  • LeoVegas offers you a 50% bonus for a £1,000 deposit, with wagering requirements of 25 times the bonus amount and a minimum stake of £5. You accept.
  • You make a deposit of £1,000 and receive £500 in bonus money
  • Your wagering is £12,500 (£500 x 25)
  • You play 2,500 hands of baccarat, at £5 per hand
  • At the end of your session, you have £395 remaining
  • You can now withdraw that £395, or use it to keep playing at the site

Online Casino Bonus Codes at UK Casino Sites

Online casinos make it a habit to hand out casino bonus codes and promo codes from time to time. A casino promo code is like any shopping promo code you might find on the internet – you enter it at the point at which you are making your purchase (or in the case of an online casino when you are making a deposit) in order to gain a little benefit with your deal.

Here is an example of how to use an online casino promo code at Karamba Casino.

Step 1

Head to the Karamba casino site and click on the ‘Join’ button, as indicated:

Karamba promo code 1

Fill in your email address and choose a user name and a password.

Step 2

Fill in your name, date of birth (required for age verification purposes), address and phone number. Add the promo code – here ‘KAR100’ – in the box as indicated. Accept the T&Cs and then click ‘Open Account’.

Karamba promo code 2

That’s it! You will receive an email from Karamba asking you to confirm your account. Once you have done that you can enjoy the games at the site enhanced by the bonus cash generated by your use of the promo code!

Online Payment Methods at the Top Casino Sites

There are several ways in which to get money into your online casino account, and as we have previously stated, we feel that the best online casinos offer several options to their players. Here we run down all the most common payment methods in the UK usually available at English casino sites.

Debit Cards

It would be virtually impossible to find an online casino in the UK that does not accept debit card payments. This is extremely handy, as practically everyone in the UK in possession of a bank account will have a debit card, and one that is issued by Visa.

You can make deposits via Visa at the top casino sites UK in the same way as you make payments online using your debit card. You enter your card number, the name on the card, the expiry date and the CCV or CVV code on the back.

Debit card deposits are usually processed instantly. Withdrawals generally take a little longer, although the best online casinos will get your money back to you as swiftly as possible. Expect though to have to wait between three and five banking days. Your debit card provider should not charge you for using a debit card at an online casino, but the casino might. The leading online casinos in the UK do not charge.

Credit Cards

The use of credit cards at any gambling site was banned by the UKGC in 2020 in order to help prevent people with gambling addiction issues from falling badly into debt as a result of their problems. If you find an online casino in the UK that says it is happy to take credit card payments from UK customers then you need to avoid it, as it is acting illegally


The most popular eWallet both globally and in the UK is PayPal. PayPal casino sites were unavailable as online casino sites UK for many years, but that has changed in recent years. Now a great number of English casino sites will happily accepy PayPal payments.

PayPal deposits are quick and easy and withdrawals should be just as quick and easy but some online casinos will put delays in place. You should not be charged any fees for using PayPal at the best UK casino sites.

You can use PayPal at Genesis Casino, Sloty Casino and Karamba Casino.


An eWallet is ‘bank account’ that you maintain and manage purely online and is also one that is not tied to any kind of traditional banking facility. Popular eWallets include Skrill and Neteller. Less common eWallets include ecoPayz, ePayments and Papaya.

At UK online casinos, both Skrill and Neteller are the most popular eWallets commonly available. Making a deposit via an eWallet at an online casino is a fairly painless and speedy process. Withdrawals usually take a little longer than deposits but they are faster than debit card withdrawals.

Your online casino should not charge you for eWallet deposits and withdrawals, but your eWallet provider will charge you a small fee per transaction.


We’ve given ‘eVouchers’ as a plural but there really is only one eVoucher scheme in the UK and that is Paysafecard. The main rival to Paysafecard – Ukash – was bought by Paysafecard in 2015, merged into Paysafecard and dissolved.

An eVoucher is a 16 digit number that you purchase at a real-world retailer and which you then use to make purchases online. This allows people who do not have (or do not want to use) online banking facilities or an eWallet account to make internet purchases, including deposits to the best online casino sites UK. Deposits are usually completed in less than a minute and the online casino should not make additional charges. Paysafecard will not charge you for purchasing a card, but it will charge ‘service fees’ if a card retains a balance after six months.

A Paysafecard is a one-off purchase as it cannot be topped up. When the money that has been placed on the card has been used, it is worthless and a new card must be purchased. As these cards cannot be topped up an eVoucher cannot be used for withdrawals from an online casino site – a different payment method must be used.

Boku & Pay by Phone

There are a few ‘pay by phone’ service available to casino players in the UK, of which Boku is the most popular. With Boku a player can use their mobile phone bill to make payments. When making a deposit, the amount of the deposit will appear on the next bill of the casino player to be paid as part of the normal billing cycle.

This payment method comes with two main caveats. The first is that payments are limited to £30 per day. The second is that high fees are usually charged by the online casino – as much as 15 percent in some cases. Payments are usually swift though.

Boku and other Pay by Phone services are not available for withdrawals. You can use Boku at the All British Casino, and MrQ.


While it is true to say that people in the UK have hardly embraced the concept of cryptocurrencies such as Bitcoin, there are a small number of online casinos that will allow cryptocurrency deposits and withdrawals. To use Bitcoin or any other cryptocurrencies at an online casino you transfer your deposit amounts between your own Bitcoin wallet and the Bitcoin wallet of the casino where you are making the deposit.

Cryptocurrency payments are usual swift, and you can use Bitcoins and other non-fiat currencies for both deposits and withdrawals. You are unlikely to incur any fees.

Casino Software Providers in the UK

Once you have been around the block a few times at several online casinos, you will begin to notice the same games (slots, in particular) appearing time and time again. That’s because very few online casinos actually create their own games but instead source them from dedicated, specialist online slots and casino games companies

There are probably over two hundred software companies all over the world, many of whom have been licensed by the UKGC to provide UK casinos with slots and casino games. Some are more popular than others, and indeed some really are the ‘creme de la creme’ (and others are the ‘crap de la crap’) when it comes to the creation of thoroughly entertaining slots and casino games. Here is a quick run down of five companies whose games are the most popular found in the realm of UK online casinos.


For many years NetEnt (founded as Net Entertainment in 1996) held onto the top spot in ANY list of the best UK casino software providers, but in more recent times that position has repeatedly been placed under threat by several up-and-comers. These Swedish-based software experts are responsible for two absolute casino crackers – Gonzo’s Quest and Starburst – and indeed their entire portfolio consits of slots, casino games and live casinos that mostly are an absolute pleasure to play.

NetEnt Starburst Gonzo's Quest

2018 was the first year that things started to slide for NetEnt after a decade of success, hit by regulation changes in the UK, their native Sweden and other global markets. The casino world was rocked in 2020 when it was announced that NetEnt were to be bought by live casino experts Evolution (formerly Evolution Gaming). The NetEnt name will surely live on though, allowing casino players to continue to enjoy all of this company’s fantastic games.

You’ll find NetEnt’s games at Genesis Casino, Sloty Casino and Karamba Casino, and just about everywhere!


Microgaming are regarded as the longest-established casino software company, having been around since 1994. This Isle of Man-based firm began life creating online casinos, but soon found that as other online casinos kept asking to use the games that they created, it would be much more profitable for them to just produce the games! Microgaming have had, over time, their fingers in more gambling pies than any other company, although sometimes those fingers did get a little singed. They are most famed for their slots and casino games, although in the past they’ve also run their own bingo and poker networks.

Microgaming Mega Moolah Immortal Romance

The aspect of Microgaming casino sites that really sets them apart from other brand new casino sites UK is their progressive jackpot slots. These slots work in the same way as a lottery – a small amount of each wager placed on a slot by all the players playing it is collected to form a progressive jackpot that climbs into the millions. The world record slot win – £13.2 million in 2015 by Brit Jon Heywood – was won on Microgaming’s Mega Moolah slot.

You can play Microgaming’s amazing catalogue of titles at 32Red Casino, Pots of Luck and the All British Casino.


Microgaming may be the longest-established casino software company on the planet, but Playtech run them close. Also based in the Isle of Man, Playtech were founded in 1999 by industry legend Teddy Sagi. They hit it big when they decided to target UK-based sports books that decided they wanted to open up new UK casino sites too. The company also invested a lot in the US market, and so were hit in 2008 when heavy restrictions on online gambling came into force but managed to survive.

Playtech Age of the Gods Kingdoms Rise

Playtech are famed for their ‘franchise’ slots. The company used to have a contract with Marvel that saw them release countless superhero-themed slots, but when Disney bought Marvel Mickey Mouse told them they didn’t want Marvel associated with online gambling. Playtech simply re-skinned all their Marvel-themed slots as ‘Age of the Gods’ and later released another franchise which they called ‘Kingdoms Rise’. Playtech also make casino games and create bingo sites via their Virtue Fusion network.

Playtech’s games are available at Casumo Casino, Slots Million and the 888 Casino.


Evolution – who until 2020 were known throughout the gambling realm as Evolution Gaming – are something of a rarity in the wagering sphere. While most of the biggest software companies on the internet see themselves as multi-taskers, Evolution do not. All their efforts throughout the time they have been in business have been purely concentrated upon a single discipline – live casino games.

Evolution Dreamcatcher Lightning Roulette

Via Evolution you can play all the casino classics such as blackjack, roulette and baccarat with live dealers via a video feed. It’s as close to an authentic casino experience as you can get online, although unlike when you’re at a real casino via Evolution you can play while you are in the bath, or when you’re sitting on your sofa dressed only in your pants.

As well as casino games Evolution make ‘game show’ style online experiences too, with bespoke tities such as Dreamcatcher and Monopoly Live. Evolution have been incredibly successful in their endeavours, so much so that they offered to buy rivals NetEnt in 2020 for a knicker-wetting $2.3 billion.

You can play live with Evolution at Genesis Casino, Sloty Casino and Grosvenor Casino.


Eyecon are not the most prolific online casino software company that’s out there, but they do have a knack for creating unfathomably popular slots. They are the brains behind ‘Fluffy Favourites’, which possibly rivals NetEnt’s Starburst and Gonzo’s Quest and Microgaming’s Thunderkick II as the most popular slot of all time. Despite the simplistic gameplay and graphics Fluffy Favourites remains as popular today as it was when it was first released. Must be the lure of those cute and cuddly critters!

Eyecon Fluffy Favourites Shaman's Dream

This company has always known when they are onto a good thing as Fluffy Favourites has spawned several sequels. So far there has been Fluffy Too and Fluffy Fairground, plus the soft toys featured in the game were blasted out of the atmosphere (which is where a lot of slot lovers would like them to end up) in Fluffy in Space. There’s been Fluffy Favourites Bingo as well, and two scratchcards. Eyecon have made non-Fluffy titles too, the most successful of all being Shaman’s Dream and Piggy Payout.

You can get ‘fluffy’ with Eyecon at 32Red Casino, Arcade Spins and Magical Vegas.

The Types of Games Available at the Best Online Casino Sites UK

They are many different types of games available at brand new casino sites UK. Here we run down a few of the most popular ones and where you can find the best sites to play them.


Here in the UK we grew up with one-armed bandits in seaside arcades and in pubs and clubs. Online slots though are derived from the type of video slots that began to appear in Las Vegas in the early 1980s. They would have mutliple paylines and bonus features such as wild symbols, scatters and bonus side games.

When video slots moved online towards the turn of the millennium, they were simply ‘ports’ of traditional video slots. Modern slots though have taken on a life of their own and have graphics, sounds and gameplay that those 80s video slots could but dream of. Slots now can have any number of reels, rows and paylines, and the very best slots should keep you very well entertained … plus if you get bored with the latest slots then you only have to wait a week and a dozen or so brand new ones will appear online!

Slots all have a measure called ‘RTP’ which stands for ‘return to player’. It is a legal requirement from the UKGC that casino sites UK software companies publish the RTP of every slot game they produce. The RTP of slot is the average percentage of the money remaining after a prolonged playing session. For example, if a slot has an RTP of 95%, then if a player beings a session with £10, after many, many spins they will have – strictly on average – £9.50 left. Slots usually have RTPs in the range of 95 to 96%. You should avoid slots with an RTP lower than 95%, and choose ones with RTPs close to 96% or even higher.


Roulette is the world’s number one casino gambling game that does not involve playing cards. Nearly everyone knows how to play roulette and online wagering fans dreams of winning big on a single number then hollering ‘let it ride’ and winning even more bigly. It’s a game where absolutely no skill is involved, and winning is purely down to good fortune.

This casino staple comes in two flavours – the original form now known as ‘American Roulette’ which has a wheel containing a ‘0’ and a ’00’, and the slightly more modern version ‘European’ or ‘French Roulette’ which just has the single ‘0’. if you are given a choice, then you should always play the latter as the odds are more in your favour. Pro tip: to get the most from your roulette experiences, learn about ALL the available bets including racetrack bets such as ‘orphans’ and ‘neighbours of zero’.

We all know about the most popular card game on the planet … which is poker! Running it a close second though is blackjack, and finding an online casino that doesn’t have blackjack is like finding an episode of ‘Eastenders’ where no one puts the kettle on for a cup of tea.

Blackjack is a simple game to play, but mastering it is not so easy. This classic card game is game without fixed outcomes and like chess, no matter the situation there’s always a ‘best move’. True, the casino will always hold an edge over the player, but by learning something called ‘perfect strategy’ that edge can be minimised to less than one percent. Blackjack is a very ‘streaky’ game though, and the true masters are those who recognise they are on a winning streak and then walk away from the table at just the right moment.

Live Dealers

Not strictly a type of game, but live casinos have grown in popularity since they were first introduced around 2010. The concept is a ‘simple’ one – a TV-style studio is decked out like a real casino with a range of popular casino titles. Players take a virtual seat at the table and the action is fed back to them via a video feed. There are no chips involved – players place their bets using a software interface just as they do when they playing a RNG version of a casino title.

The most popular games are the ones you’d most expect to be popular – blackjack, roulette and baccarat. Other casino games are offered too such as casino poker, sic bo, pai gow poker, dragon tiger and even craps. There are a few keno style titles too, such as Evolution’s Dreamcatcher. A live dealer casino is as close as you can get to the casino action without having to leave your settee!

Other Casino Games

Here is a quick rundown of the casino games also found at many of the best UK casino sites.

  • Baccarat – not that popular with UK-based players but well worth learning to get to grips with
  • Video Poker – a one-player version of draw poker in which you try and gain the best hand possible
  • Casino Poker – play poker games such as Texas Hold’em head-to-head against the dealer
  • Craps – the world’s most complicated dice game. Hit those lucky sevens and avoid the dreaded ‘snake eyes’
  • Scratch Cards – just like the ones you get from the petrol station – just don’t use a real coin to rub off the panels!
  • Sic Bo – the Asian dice game that works in virtually the same way as roulette, but with dice
  • Pai Gow Power – an odd but entertaining poker variant where you make two hands from the seven cards you’re dealt

You may also find non-casino games at UK online casinos, so as bingo and virtual sports games.

The Best UK Mobile Casinos

The top 10 casino sites in the UK have always offered mobile apps that you were able to download to your devices so you could play online via your phone or tablet.

The Best Fast Payout Casino Sites in the UK

If there is one thing that perplexes UK casino players it’s the fact that withdrawals take sooooooo much longer than deposits. Shouldn’t withdrawals be as speedy as deposits? You are just moving money across the internet whether you are depositing or withdrawing, so why the difference?

The answer is that withdrawals should be as speedy as deposits, and with the best UK online casinos they are. The truth is, many online casinos like to keep a hold of your money for as long as they can, so it can sit in their bank accounts earning interest. That’s why UK casino players have to put up with a ’48 hour pending period’ and a ‘3 to 5 day processing period’. In truth, it’s all just flim flam. Here at Safe Betting Sites we feel the best UK casino sites are those that get your requested money to you promptly.

The Best New UK Online Casino Sites

While it is true that the internet is somewhat flooded with English casino sites, that does not stop brand new casino sites from springing up, seemingly on a weekly basis. That can only be good news for online casino players in the UK, as many of these sites attempt something new and different in an effort to get themselves noticed. They could have a rewarding welcome bonus, a unique or quirky approach, or they could offer exceptional levels of customer service. It often pays to take a look at something that’s maybe a little new and different, as you never know what benefits you might uncover.

Here is a quick list of the three best casino sites UK that have been unleashed onto the internet in recent weeks.

UK's Best New Casino Sites of 2021

And in conclusion …

You are really spoilt for choice if you want to play at an online casino in the UK. No matter your favourite wagering discipline, you’ll always find a place to play – indeed, you could find you have many dozens of options from which to choose.

Speedy payouts too are a bonus, plus fair and square promotions and an extensive range of the best games available.

Why gamble by following the advice of others? Our experts really know what they are talking about, as you’ll find out if you trust what we tell you.


Why do UK casinos have to be regulated by the UKGC?

Just think, if you did not need a licence to operate an online casino, you could do what you want. You could refuse to pay winnings, refuse to honour withdrawals and completely ignore customer communications … and that’s what some online casinos do! You are legally required to have a UKGC licence to open a UK-facing online casino, and if you do not follow UKGC guidelines about fair play and customer care then at best you will have your licence suspended or revoked, and at worst you could find yourself facing a heavy fine! UKGC licences are designed to protect online casino players in the UK.

A casino that does not have a UKGC licence says it will accept me as a player. Should I join?

No! If they accept UK players but do not have a UKGC licence then they are acting illegally. Would you trust your money with a company that is not acting in a legal fashion?

If a slot has an RTP of 95%, if I spend £10 playing it after a while am I guaranteed to have £9.50 left?

No - the RTP of a slot is only a measure of its 'generosity' and not a guarantee. The '95%' figure is only a measure of returns on average after a very long playing session. You are not guaranteed to win or lose while playing a slot, but the higher the slot's RTP, the better the chance you have of ending your session in profit.

I have self-excluded at one site, and now other sites won't let me join them. Why?


I found a 'winning roulette strategy' for sale on the internet. Should I buy it?

No! Think about it, if you discovered a profitable betting strategy that genuinely, 100% worked, would you tell anyone else? Of course not! All 'winning betting strategies' can safely be ignored. They work in principle but fall foul to table limits and inevitable losing streaks. If you could guarantee wins at any gambling game, then casinos would stop offering that game.

If I learn 'perfect strategy' for blackjack, would it make me a guaranteed winner?

No, but it will minimise the edge that the casino has over you. Blackjack unlike roulette is not a game of fixed outcomes - it depends on actions taken by a player. If you do dumb things like hitting on 18, then you are not going to win a great deal. Perfect strategy is knowing what to do in any given blackjack situation.

Which casino site has the best odds?

This is a question that cannot be answered! Games such as roulette, blackjack (if played using perfect strategy) and others have the same odds no matter which casino you are playing at. Slots-wise, look for a casino with a high number of NetEnt's games, as NetEnt's slots usually have decent RTPs.

Why do online casinos not offer poker?

Some do, but most don't (unless you count video poker or casino poker). Getting ten people around a virtual poker table requires dedicated software and a decent amount of bandwidth. Most casinos don't want to stretch that far.

What's the difference between virtual sports and eSports?

Virtual sports are computer-generated simulations of real-world sports that players can place wagers upon. Esports are real people playing popular competitive video games such as Legend of Legends, Counter Strike: Global Offensive and Defense of the Ancients.

Why should I play European Roulette over American Roulette?

Because American Roulette has the '0' and '00' on the roulette wheel, as opposed to only the '0' of European Roulette. If the ball lands in any of these numbers than all outside bets (i.e. odd/even, black/red) lose. You have double the chance of losing an outside bet if you choose American Roulette over European/French.
