The best slot sites UK 2023

  • Are online slots safe? – Yes.
  • Are there really hundreds of different slots online? – Yes.

Basically, online slot games are perfect when you are looking for action, entertainment, safety, and variety. From slots based on popular TV series to high-stakes jackpots, there are many options on the market.

Are online slots legal in the UK?

It is legal and safe to play slots online in the UK. Modern online slot games are made to extremely high standards. The main component you need to know about is the Random Number Generator (RNG). An RNG ensures that the results are fair.

Explained in simple terms, an RNG is a program that uses advanced algorithms to produce random results. There are some parameters within which online slots work, e.g. B. Volatility and payout ratio (RTP = Return to Player). Crucially though, RNGs ensure slots are fair.

But couldn’t a casino operator manipulate the RNG? Not every online slot licensed in the UK has been audited and certified by a third-party agency such as eCOGRA and iTech Labs. These companies check the randomness of an RNG, issue a fairness certificate and regularly monitor the software.

Without this certificate, an online casino cannot obtain a license from the UK Gaming Commission or other regulatory bodies. Therefore, when an online casino is licensed, you can be sure that the online slots are 100% fair as well. In addition to security, reliability, and fairness, modern online slots must live up to responsible gambling within specific parameters. This license condition ensures developers and operators do not encourage irresponsible behavior.

Why play slots online for real money

There are several advantages to playing online slots. Players can easily play for real money and also multiply their winnings thanks to the benefits of online portals such as casinos. Furthermore, it is no longer necessary to go to a brick-and-mortar casino, which can be stressful or financially impossible for some players, it is possible to play simply from the comfort of your own home, on the go or anywhere else, where an internet connection is available. This allows players to easily play progressive and classic online slots for money with high RTP (Return) percentages and generous casino bonuses that can be used while playing these games to maximize winnings.

Did you know that all online slots are tested and certified for fairness by drafting agencies like eCOGRA?

Should you play online slots for real money or demo money?

The answer to the question ultimately depends on you. I like to test the slot machines with play money and try to get an idea. How do the bonus games work, when do I get free spins, how do the wild and multipliers work; and ultimately: Do I enjoy the online slot?

But as soon as I know if I like a slot, I switch to real money. Because one thing is clear: Slots are only fun with real money! It is best to play online slots with real money but no deposit is required. Of course, the best way to do this is with a real-money no-deposit bonus. Admittedly, such offers are rare, but they exist – and if they do exist, you are guaranteed to find them in our bonus section.

How to choose a real money slot?

The player's choice should be based on informed decision-making and here too it is necessary to remember some important factors and at the same time it is important not to forget one's own preferences.

Time Needed: 10 Minutes Tools Needed: Laptop/Mobile Software Needed: Email
Step 1

Online slots that suit you

Check out any of our top-rated casino sites and you will find a variety of slots. From free online casino games to jackpot games, there are countless options.

Although every online casino has its own focus, you can assume that there are at least 100, but often well over 1,000 online casino games in a modern online casino. Because of this, it’s easy to find a game that suits your style – provided you know what you’re looking for.

  • Online slots with bonus buy function
    Before we dive into the criteria that will help you find the perfect online slot game, let’s briefly review online casino games where you can buy the bonus round (Bonus Buy Slots). On these games, you can pay a premium and receive a guaranteed bonus. The costs vary depending on the size of your bet. However, the main feature is that you are paying to receive a guaranteed bonus.
  • Casino slots with hold and win function
    With the Hold and Win feature, you collect symbols that accumulate to an ever-increasing win. Usually, three re-spins are associated with the appearance of a bonus symbol. If more bonus symbols appear when using the re-spins, the re-spins are charged again, again up to 3. The bonus symbols that have already been spun remain frozen and only the remaining reels continue to spin. With this mechanic, all bonus symbols that you spin add up.

Things to look out for when choosing online slots

There are thousands of casino slots online. Browsing isn’t easy if you don’t have a list of things to look out for. To help you choose the best game, we suggest you take a look at the following features:

  1. Theme
    Find a slot that suits your preferences. The selection is diverse: everything is represented, from TV series and Egyptian themes to pop stars.
  2. Withdrawals
    Ultimately, it’s all about how much you can win. Each slot has different payout percentages and mechanics. So make sure that you don’t pay extra unnecessarily.
  3. Risk
    No slot in the world will pay you back your stake, so you should keep an eye on the risk of loss. Important indicators here are the volatility of a slot and the RTP value (Return to Player).
  4. Watch out for volatility
    All slots are powered by an RNG. This ensures that the results are random and fair. Two variables are programmed into RNGs that determine a slot’s overall payout potential, volatility and RTP. These results should not be taken as a guarantee of how much you will win as they are theoretical values. However, what is true is that your win rate should reflect volatility and RTP values ​​over time. Volatility represents the frequency with which an online slot will theoretically generate a return on your investment and its relationship to the size of the payouts. In other words, how often you will win a prize and how big it will be.

    • Low volatility slots
      Low volatility slots are designed to payout more frequently than medium and high volatility games. Prizes are usually smaller but more even.
    • Medium volatility slots
      These games fall somewhere between low and high volatility slots. This means that they pay out less frequently than low-volatility games, but more often than high-volatility slots.
    • High volatility slots
      The defining feature of high volatility slots is that they don’t pay out often, but when they do, the winning sum is large.
  5. Pay attention to the RTP
    RTP stands for Return To Player. This score tells you how much you win on average per 100 credits wagered. For example, an RTP of 98% means that you theoretically get 98 credits back for every 100 bets. Again, this score is not a guarantee. Sometimes you win 110 credits for every 100 you wager, sometimes it’s 90. However, over time, your results should move towards the RTP. Therefore, when looking for a slot, keep the volatility and RTP in mind.
  6. What is your budget?
    Never spend more than you have. One of the golden rules of gambling is that simple. Only play with money that you can lose without getting into financial difficulties. If you are a complete novice, you can play free online slots. If you have money to spend, new online slots allow you to adjust the bet, the number of active paylines and the amount you bet per payline. A rule of thumb is that you should be able to play at least 500 bets. So if you want to spend £100, your bet per spin should be £0.20 or less.

What types of online casino slots are there?

In addition to the general theme of a slot game, you can look at the underlying structure. Most games have five reels. However, those with a classic theme can have three, while new online slots can have six, seven or even more reels.

Therefore, you need to know what is available and in turn, find a structure that suits you.

1. Number of reels

How many reels can online slot games have?

  • 3 reel slots
    These online casino slots are often referred to as classics as they reflect games that were popular in the 70s and 80s. In addition to the three reels, these slots often have between one and five paylines.
  • 5 reel slots
    About 90% of the slots in UK online casinos have five reels. These games offer more paylines and features than 3-reel slots, which is why they form the basis for the current video and progressive jackpot slots.
  • 6-reel and 7-reel slots
    Developers have gotten creative over the past few years and have taken slot gaming technology to a new level. Thanks to innovations like Megaways, traditional formats have been improved. Today there are games with six, seven and sometimes even more reels.

2. Game Type

What Kind of Slots Games Can You Play Online? Let’s take a look.

  • Classic Slots and Fruit Slots
    Classic is another term for the “Fruit Slots”. This means that classic online slot games often feature cherries, grapes, watermelons, oranges and lemons. In keeping with the classic theme, these games also often have symbols represented by bells, bars, and sevens.
  • Video slots
    The best online slots usually fall into this category. There is no specific theme or feature that you can use to define what a video slot is. The main feature to look out for is reels. Video slots usually have five reels and a selection of wilds and bonuses.
  • 3D slots
    3D online slots are a subgenre of classic and video slots. They’re a subgenre because they share the main traits of both classics and video slots but literally offer a different perspective. Instead of just showing you the reels and nothing else, 3D slots show you a visually stunning spectacle.
  • Progressive Jackpot Slots
    These online casino slots take a small percentage of all bets and add them to a common pot. This allows the prize pool to grow exponentially. As soon as someone hits the right combination, they hit the jackpot. This makes progressive jackpot online slots more lucrative than those with fixed payouts. By the way, the latest, spectacular, progressive jackpot comes from Relax Gaming. You can win up to £10,000,000 with the Dream Drop Jackpot!
  • Megaways Slots
    Megaways is a payout structure developed by Big Time Gaming. The system can be applied to existing online casino games or used to create new casino slot games. The main feature of a Megaways slot game is its random payline structure. Basically, you never know how many active paylines there will be on a spin. There are often six reels and depending on the alignment, Megaways slots can have up to 117,649 paylines.
  • Cluster Slots
    Traditional online slots have a set number of paylines across which you need to line up matching symbols. Cluster slots do not have paylines. Instead, you need matching symbols that land in clusters, meaning they must be touching.
  • Multi Payline Slots
    Classic online casino games often have a payline (sometimes up to five). Today, online slots, both old and new, have multiple paylines. This can be a predetermined number or a random number. The main requirement here is that you need to land matching symbols on active paylines from left to right.

How to play online slots for real money?

The process of playing online slots for real money is very simple, but it requires an informed decision on the part of the player who wants to play these games and actively engage in them.

  1. Choose the best real money online casino
    First of all, you can use our clear table, in which you can find trusted and rated casino portals, from which a selection is available for UK players and where you can play various and popular slots for real money.
  2. Compare bonuses, providers and fairness
    The next step is to compare important factors such as casino bonuses applicable to online slots and their fairness, the diversity of software providers, but also the credibility and security of the casino in question.
  3. In case it is possible to read the reviews
    In case you do not want to compare all the factors, it is possible to read the available reviews.
  4. Choose an online casino website and sign up
    It is also necessary to complete the registration and verification process to create a game account and access the entire catalog for online slots for money.
  5. Make a deposit
    With an available payment method, it is possible to deposit funds for a real money deposit.
  6. Use the welcome bonus
    By activating it after making a deposit, it can also be activated automatically. For example, a welcome bonus is available.
  7. Choose your favorite game
    Bet and enjoy playing games.

How can you increase your chances of winning?

There are certain games where skill can play a role at the table. For example, understanding math can help you reduce the house edge in blackjack When it comes to online casino slots, there is not much you can do. Because the outcome of a spin is random, you cannot increase your chances of winning However, what you can do is do your research before you shoot. Making the right choices can improve your overall experience and get the most out of a game.

  • Read our reviews
    The starting point for any aspiring slots player should be our slots reviews, which you can find on this page. Find out what we have to say about today’s top online slots.

  • Watch slot streamers play
    There are slots fans who have found ways to combine strategy and entertainment. Although these players can’t show you how to win or develop strategies that are guaranteed to work, they’re fun to watch.Some online slots streamers that you can find on Twitch are:

    • Roshstein
    • CasinoDaddy
    • ClassyBeef
    • DeuceAce
    • Xposed
  • Create your slot strategy
    As we have already said, there is no way to increase the odds in your favor when playing slots online. This in turn means that there is no strategy that can guarantee you a win. However, it is possible to tweak your approach. In addition to reading our reviews and watching slot streamers, you can also learn how to manage your money. As mentioned before, you should have at least 500 missions in your arsenal. Also, consider a game’s volatility and RTP. How often is it likely to be paid out? Will the average win be big or small? What is our total potential? Answer these questions and see the wins before you spin.

How do online slots work?

Once you know the basics, you demystify the process. In other words, if you know how slot games work, don’t get emotional. You know your scores will fluctuate and you won’t get frustrated because it’s all part of the game.

With this in mind, the average online slot works like this:

  1. You place a bet and press the spin button.
  2. The reels spin and come to a stop.
  3. There is a selection of symbols on each reel. Thanks to the rotation, they are now lined up randomly.
  4. A certain number of paylines are crossed by the reels. If you can match three or more symbols (usually left to right) across active paylines, you win a prize.
  5. To help you get winning combinations, a slot can contain wild symbols. These can substitute for all other symbols except scatters.
  6. If you land enough scatter symbols you will be awarded a bonus. This can be free spins, a mystery pick’em round or something else. The point here is that scatters unlock special features that are separate from the main game.
  7. When you play a progressive jackpot slot online, the top prize has no fixed value. Instead, you play for the currently displayed jackpot, which increases in value every time players make a bet.

Practice for free

To help you get a handle on what today’s casinos have to offer you can play online slots for free. You must be registered with a site to unlock this feature. In demo mode, real money games become free online slot games. These games are not only fun but also allow you to learn the basics.

Best online slots providers

Every online casino game developer brings something different to the table. Some focus on entertainment, while others push for bigger jackpots or more ways to win. Our recommended casinos offer games from different manufacturers. However, the three hot picks below should provide a good starting point for anyone just starting out in the business.

  • NetEnt slots
    NetEnt is often regarded as the world’s leading online casino slots developer. Not only does NetEnt create more games than anyone, but they strike the right balance between style, substance, payouts and theme. Some of the hits include Starburst, Gonzo’s Quest, and Guns N’ Roses.
  • Yggdrasil Slots
    If you want innovation and creativity, Yggdrasil slots are perfect. This developer creates highly stylized games that not only offer rich storylines and animations, but also nice features like levels. In many ways, Yggdrasil slots are more like video games than casino offerings. Some hits to watch out for are Champions of Rome, Jackpot Raiders, and Vikings Go Berzerk.
  • Big Time Gaming
    Big Time Gaming is the company behind Megaways. This payout system has revolutionized online slots. Thanks to the innovative structure, you can randomly activate up to 117,649 paylines on every spin. Additionally, Megaways can be applied to many of the best online slot games in the industry e.g. B. Bonanza Megaways, Gonzos Quest Megaways and Vikings Unleashed Megaways.

Criteria for choosing real money slots casinos UK

During the selection of online slots, which are really high quality, safe and provide great fun for players, it is necessary to take into account several basic factors, without which our review of slots online for money is not complete. These are in particular the following criteria:

  • Simple registration process
    Not only registration, but also verification should be simple and clear within the registration process, and its conditions should be comprehensible to the average user. At the same time, registration should be fast.
  • Generous bonuses
    Bonus programs within an online casino with quality slot machines should not only be rich and interesting but should also have game bonuses whose conditions and requirements for withdrawing selected funds are fair.

    Another point is the level of experience that players have in the portal, i.e. whether the pages are clear, and whether the games do not contain errors.
  • A wide selection of online slots

Real money slots online pros and cons

No, most online slots don't have a jackpot, but we have to differentiate between the following slots when we talk about jackpots: There are jackpot slots. There are between 1 and 4 jackpots, the amount of which is fixed. Then there are progressive jackpot slots. Again, there are between 1 and 4 progressive jackpots. The progressive jackpot means "growing jackpot". This can continue to grow until it is cracked by a player. A certain percentage of each bet per spin flows into this jackpot. Players who are not very familiar with casino words often talk about a jackpot when they actually mean the maximum win of a slot.

No, online slots are not rigged. Online slots are much safer than land-based casino slots. No crook can have a hand in this. At the same time, it is also not possible for players to manipulate the slots. Online slots work with random number generators running on external servers. These are protected with the best security measures available online.

This depends on which slot game and on which portal the player plays and bets real money. It is very important to make an informed decision and use only licensed games.

Yes, if the slot game supports it and if the player registers at a real money gaming online casino.

RTP is the English abbreviation for Return-To-Player, which indicates the return to players who bet their money on the given slot. This value is given as a percentage and it is recommended to play games from 95% and above.

The best are games with a high percentage of RTP, but also according to the volatility indicator and the preferences of the player himself. The higher the volatility, the higher the winnings can be and vice versa. However, the risk also increases proportionally.

Online slots work on the principle of random number generation, which guarantees a fair game for every player. This Random Number Generator generates numbers within reels and game rows in a random manner, without external influence.

According to the rules of the specific slot game. Not all slots necessarily support the bonus round option. This is mainly triggered by specific combinations or other elements of the game.

This depends on the specific slot game, some real money slots may offer lower winnings, others up to hundreds of thousands of jackpots, according to the regulations of the specific jurisdiction. Progressive jackpots gradually increase their jackpot.

Through a mobile online casino or by downloading a specific game through the app store.
