Best Real Money Online Casinos in the UK

For many years, the UK gambling industry has exhibited steady growth, with revenue climbing year-on-year. The number of new UK online casinos popping up on the market is truly astounding. But if they are newcomers, it's often harder to get hold of information about them, which is why safety checks are of paramount importance.

UK casinos are known to be some of the safest out there for players. Any casino that accepts players from the UK has to be licensed by the UK Gambling Commission. And the best thing about the UKGC is that it follows fair, transparent, and strict terms and practices.

Recently, the UKGC announced a package of new measures. They will strengthen the protections and controls for online slots games, meaning only the safest, most reliable casinos will make the cut.

Overall, as a player, there is no reason to steer clear of fresh platforms. Our team researches new online casinos in the UK and verifies whether they're appropriately licensed. You don't always have to go for the big names - brand new casinos can have a lot of potential too. And as long as the regulatory authorities and our specialists approve them, it's safe to check them out.

Advantages of New Slot Sites  

Sometimes, new slot sites are considered inferior to established platforms. We can assure you that 'new' is actually a good thing.

If new casinos want to succeed in this highly competitive field, they need to bring something fresh and exciting to the market and be accessible for all players. Here are a few reasons why new casinos can be among the best online slots sites in the UK:

  • Generous bonuses: New casino bonuses are the most effective way to attract players to a platform. So, there's a host of sign-up deals up for grabs.
  • Greater gaming choice: New sites feature well-established game providers as well as newcomers, and new game titles are released regularly.
  • Mobile optimisation: The gaming scene has gone mobile. And while not all established platforms have caught up, new sites are mobile-optimised from the get-go.
  • Better and faster payment options: Back in the day, you could only make online payments with credit or debit cards. But now, new platforms integrate a wide variety of payment methods.
  • Innovative features: New casinos often take the playing experience to a whole new level - advanced gameplay features, live games, better usability, creative jackpot concepts, and more.

Casino Bonuses in the Great Britain

The UK Gambling commission specifies that all terms and conditions relating to online casino bonuses must be accessible. These include the restrictions, minimum wagering requirements, and other essential considerations. Casinos featured on our lists demonstrate compliance and treat customers fairly.

Now, let's talk about the types of bonuses. Below are the top casino bonuses and a brief description of them:

  • Welcome bonuses (also called sign-up bonuses) are the most common casino bonuses in the UK and, in fact, in the world. The percentages vary. For example, a player could get 100% of their first deposit of £200.
  • No deposit bonuses are exactly that - a small bundle of bonus funds with no deposit required, e.g., £20. Those usually take the form of a fixed cash sum that is credited as soon as a new player completes registration.
  • Free spins are offered for a particular slot game that the casino wants to promote. With free spins, you can bet without the risk of losing but also get a chance to win real money. It can be 100, 200, or any amount of free spins.
  • Cashback is a percentage of the player's net losses over a given period that they receive as a refund. Unfortunately, casino gameplay doesn't always go to plan, so the site may want to give players cash or credits to make up for it.
  • A VIP programme for high rollers is a type of reward mechanism. Obviously, the best casino bonuses are reserved for the most loyal players. A VIP player can enjoy special perks, free spins, higher limits, and a range of other advantages.
  • Tournaments are competitions between casino players held for poker, slots, blackjack, and other table games. For example, in a slot tournament, you play for a specific amount of time and with a certain number of casino credits. The best-performing player wins the prize.

Online Slots in UK Licensed Casinos

Slot machines have always been a massive part of the casino experience. And as physical machines moved further into online slots in the UK, casino websites decided to dedicate large portions of their platforms to slot games. On average, UK licensed casinos offer a selection of anything between 1,000 and 2,000 slots.

Since slots are some of the simplest games in terms of rules and gameplay, you might want to switch things up from time to time. The massive selection of UK slots online lends itself perfectly to anyone who doesn't want to tie themselves into a specific niche. As soon as you get bored with one machine, you move on to the next with a couple of clicks.

Slots online in the UK come in all shapes and sizes. Some people opt for simple, traditional three- or five-reel games that remind them of the classic machines. Others choose modern, more complex variations with top-of-the-range graphics and immersive sounds.

The top licensed online casinos also offer slots with different structures and levels of difficulty. On the one hand, you have the standard five reels. On the other hand, you have Megaways slots with tens of thousands or even hundreds of thousands of ways to win.

Major Types of Real Money Slots

We've already mentioned that the number of slots online for real money is impressive. But it's not all about the volume; it's also the variety of games. These days, there is a massive range of slots available, but we'll cover the most popular ones:

  • Classic slots (3-reel slot) are a homage to the one-armed-bandit slot machines known as the Liberty Bell that consisted of three reels and a fixed jackpot. Modern three-reel slots follow the same format but have additional features and winning combinations. These games are loved players who value their simplicity and straightforward interfaces.
  • Video slots are the type of slots you're probably most familiar with - impressive graphics, more dynamic gameplay, and a least five reels. Most people who play slots online in the UK choose this format. These slots are based on various themes and narratives and are constantly enhanced with bonuses, wilds, free games, and more.
  • Megaways slots are a unique, even 'radical' way of playing slots. They involve a random reel modifier that makes the symbol height on each reel vary with every spin. Believe it or not, there are 117,649 ways to win.
  • Progressive slots are the ones with no fixed jackpot. Instead, the prize increases every time somebody plays a slot game. It accumulates over a certain amount of time (but entirely at random) until one winner takes it all, and the winnings start to accumulate again.

5 Best UK Online Slots Ever

There could never be one objective list of the best UK online slots. Yet, we did our best to shortlist five slots that players love:

  • Starburst - 96.09% RTP, low volatility - This world-famous five-reel, three-row slot was developed by NetEnt in 2013. It's packed with fun features and energising gameplay. For example, you can trigger free re-spins with symbol combinations. Or you can score an exciting bonus round.
  • Bonanza - 96% RTP, high volatility - This slot was developed by Big Time Gaming run on the Megaways engine (don't forget- thousands of possible paylines!). This gold-mining-themed slot has a fun concept, looking for Diamonds, Rubies, Sapphires, and Emeralds, as well as for bars of gold.
  • Rainbow Riches - 95% RTP, medium volatility - It has stood out as one of the top UK online slots since 2009. It is a vibrant, Irish-themed game by Barcrest with a classic 5-reel structure, ten paylines, and 18 winning combinations.
  • Book of Dead - 94.25% RTP, high volatility - This Play'n Go development is quite simple in its structure with low-pay symbols (10 to Ace) and a few high-pay ones (Anubis, Osiris). If you're hoping for a big win, the best way is to play long enough to land a bonus round.
  • Slingo Rainbow Riches - 95.6% RTP, medium volatility - This game combines the best features of slot play with bingo. For a win, you need to complete lines on a 5x5 grid of numbers. But the best thing about it is the seven potential bonus round prizes.

Best Payout Online Slots in the UK

Every slot has a payout (also called RTP or return-to-player) associated with it. Essentially, it is a measure of how much the game pays back to its players in the long term. On average, the percentages range between 85% (considered very low) to 97%.

As a smart gambler, you know you need to find the best payout online slots in the UK. Playing for entertainment is fine, but you also want to have the best chance of winning and the best value for your money.

Live Dealer Casinos for UK Players

Live dealer casinos bring the gambling experience to a whole new level. These are immersive games held in cutting-edge surroundings, so casinos with live dealers are at an advantage.

Below are a few most sought-after  games that you can play with a dealer in real-time:

  • Roulette - Pretty much all live casinos will offer this game. In live roulette casinos, you can even find a number of different rooms with different variations. The rules are the same, but it's a real wheel spinning.
  • Blackjack - After roulette, blackjack is the most prevalent game in top-rated casinos with live dealers. The idea behind the game is essentially that it's everyone against the dealer. It's very exciting to be in front of an actual person for this.
  • Poker - It's hard to substitute sitting at a poker table and communicating with others. But live casinos succeed in the task by using camera feeds and chat rooms. Hold 'em, Omaha, and Hi-Lo poker variants are all lots of fun.
  • Baccarat - Like in poker, there is a real dealer that players are competing against. But you don't need to travel all the way to a real-world casino to try your luck at a winning hand closest to 9.

Best Live Casinos List for the UK      

This part of the page is dedicated to the best live dealer online casinos. What do we mean by the best live casino? It's the one with the best track record and one which has been proven safe for UK players.

The list below details the top live casinos that have been around for a long time and new live casinos that are still great choices.

Secure Payments Methods for Online Gambling  

Payment methods are an important consideration for any casino. Before you start playing, you want to find out which online casinos accept PayPal or any other of your preferred payment methods. Let's talk about several services in more detail:

  • PayPal is perhaps the biggest name in the industry. PayPal online casinos in the UK aren't hard to find because the company has an established relationship with the Gambling Commission. It has powerful fraud and consumer protections in place, so you're in safe hands.
  • American Express is a popular banking method, which sometimes gets you amazing welcome bonuses and promotions. Online casinos that accept American Express in the UK also encourage a safe gambling environment with tight security encryptions.
  • Visa and MasterCard remain the most commonly used credit card companies in the world. And naturally, there is no shortage of casinos with these two payment options. These are established names that are known for processing transactions quickly and securely.
  • Skrill casinos in the UK are growing in number every year, and there is a good reason for that. A Skrill wallet can house credit cards, debit cards, and real cash in multiple currencies, including GBP. With that much convenience, it's no wonder so many players opt for Skrill.
  • Paysafecard is a prepaid card/voucher, useful for those who don't link their bank account or credit card to casino sites. This method is mostly used for deposits. For withdrawals, you'll need to look for another method.
  • Bitcoin is finding its niche in the online gambling sector. However, there are some limits for regulated and licensed UK casinos. So, you might want to look for BTC integrations into services like PayPal. Overall, BTC payments are extremely reliable and fully anonymous.
