Guide to Choosing the Best Slot Site
With so many options to choose from, selecting a reliable new slots site can be a potentially confusing and time-consuming business. However, Editor Anita and our team of reviewers have heaps of experience doing just this, and so we have put our heads together to come up with our top tips when you are looking for the best and most trusted slots sites to play at.
1 – Know Your Preferences
Knowing what you want in a slot site is key to having a great experience. While all our recommended sites are dependable and offer generous welcome bonuses, the choice of games often makes the difference. If you enjoy traditional slots, look for sites with classic slots featuring basic reels and paylines. If you’re into innovation, check out sites offering games with the Megaways mechanic, which provides a dynamic reel layout and thousands of ways to win. For fans of progressive jackpots or complex bonus rounds, finding a site with a broad selection of these games is essential. Utilize our Slot Games page to explore games by type and check out the Slot Game Providers section to find games from your favourite developers. Knowing your preferences lets you choose a slot site that matches your taste, ensuring a more satisfying experience.
2 – Test the Site on Your Mobile
Mobile compatibility is crucial as most players now prefer gaming on the go. Even though all our featured slot sites are mobile-friendly, performance varies. Before depositing, assess the site on your phone or tablet to ensure it runs smoothly without delays or glitches. A good mobile site should load quickly, be easy to navigate, and have intuitive controls for a seamless experience. If the site is slow or buggy, it might affect your enjoyment, so it’s wise to avoid such platforms. Many top sites also offer dedicated mobile apps, which can enhance the gaming experience. Always prioritize sites that optimize for mobile to ensure you can play wherever you are, without technical issues getting in the way.
3 – Choose Your Bonus Carefully
Welcome bonuses can add value, but it’s essential to understand the terms. Due to regulations, bonuses may seem smaller, but they’re still worth exploring. Before committing, examine the wagering requirements and how long you have to meet them. Some bonuses attach to both the deposit and the bonus amount, while others only to the bonus. Check for any wagering on free spins, too. Also, look for the ‘maximum conversion amount,’ which caps how much bonus money can be converted into real cash. Bonuses that offer lower wagering or no wagering are ideal, as they can provide better returns. For more insights, visit our best casino bonuses page to find offers with fair conditions and clear terms.
4 – Check Out the Variety of Games
A quality slot site should offer a broad game selection, which may include slots, table games, live dealer options, and even scratch cards. While dedicated slot sites focus heavily on slots, you might also enjoy other types of games. If you like playing live dealer games, ensure the site offers them, as some slot sites may not. A well-rounded site can cater to different gaming moods, from quick slot sessions to immersive live dealer experiences. If you’re interested in exploring other games beyond slots, look for sites with a diverse portfolio. Having options means you can switch between different types of games without needing to sign up on multiple platforms.
5 – Ensure the Deposit & Withdrawal Methods Work for You
Having convenient payment options is vital for a smooth gaming experience. Most slot sites offer a variety of methods, from traditional debit and credit cards to e-wallets like Skrill and Neteller. Many sites also accept PayPal, PaysafeCard, and Pay by Phone, which lets you add deposits to your mobile bill. Newer options like Apple Pay and Google Pay are also becoming popular. Be aware, though, that certain payment methods may exclude you from welcome bonuses. Before you sign up, check that the site’s payment options suit your needs. Fast withdrawals are also a plus, so look for sites with efficient processing times, especially if you prefer quick access to your winnings.
6 – Provide Your ID Documents Straight Away
To comply with ‘Know Your Customer’ regulations, you’ll need to verify your identity. While some sites don’t ask for these documents immediately, uploading them when you sign up can prevent delays later on, especially when it’s time to withdraw. Common documents include a photo ID, proof of address, and sometimes a payment method verification. Preparing these documents in advance ensures a smoother process and avoids potential frustrations. Look for sites with clear instructions on the verification process, as this often indicates a commitment to player convenience and security. By providing your documents early, you can focus on playing without worrying about verification issues disrupting your experience.
Benefits of Playing Slots Online
We classify anywhere where you can play online slots as a slots site. Both online casinos and bingo sites feature slots, and so we consider both of these to be in this category. Simply put, playing slots online (responsibly) is a fun way to the pass the time and possibly win some money. Convenience plays a part too. There’s no need to visit your local arcade or casino in order to enjoy spinning reels.
Our featured sites and the ones in our directories only include those that are licensed and regulated by the UK Gambling Commission, so you can be assured of having a safe and secure online gaming experience as well.
Slot sites bonuses
Unlike land-based venues, online slot sites run numerous incentives and bonus schemes to entice and retain players. These slots bonuses can take many forms — from a no deposit bonus, to deposit matches, to bonus spins — but whatever kind of bonus you pick up, it will be a way of getting greater value from your online slots playing experience. While caution needs to be observed before committing to a bonus, there are plenty of worthwhile deals to be had.
Exceptional choice and variety
Unlike land-based venues, you’ve got a huge amount of choices in terms of game collection. Some of the best online slot sites features more than 1000 different games. It’s also worth mentioning that online slots can take a myriad of forms; new innovations in gameplay and themes are being introduced all the time, so when you play slots online the choices are almost unlimited.
Play on the go
The vast and rapid improvement in mobile slots technology in recent years has meant that mobile casinos today offer a vastly superior gaming experience than that of a few years ago, so much so that many players now play almost exclusively on their phone or tablet. Being able to access high quality slots at any time, no matter where you are, is one of the main draws of mobile slots, and the range of UK slots sites who offer a first-rate mobile gaming experience is growing all the time.
Improved RTP
Online slot games generally have a vastly superior RTP (return to player percentage) than the slots you’ll find in clubs or land-based casinos. This means your bankroll goes further and you get far better value than you get when playing slots at a bricks and mortar site.
Advantages of Choosing a UK Slot Site
While every business ever created wants to generate revenue and profit you can be sure that if a slots or casino site is UK registered then your money is in safe hands and that the set up of the site has to meet strict rules and regulations to ensure you are treated fairly and that the games are all monitored and checked by various governing bodies, not just the UK Gambling Commission, but the likes of the Malta Gaming Authority and Alderney Gambling Control Commission. The role of UK slot sites is to host a safe and reliable online space where you are able to play games, and can be trusted to provide players with other services such as welcome bonuses, gamification features, customer support and more.
Steps to Sign Up for a Slot Site
Signing up/registering with a slots site is pretty simple and generally follows this path. First of all, click register/sign up.
You will then be required to enter your email address. From here, an email with a link will be sent to your email account. When you click this link, you’ll be taken to the slot site and asked to provide a username and password.
Once you’re registered, you’ll be required to provide ID documentation as part of the KYC regulations. This means proving your identify and age.
KYC Requirements (Know Your Customer)
Although the process may be slightly different between casinos, in order to play the games, you have to provide the following:
- Photo ID (Driver license/passport)
- Proof of Address (household bill/bank statement)
You might also have to prove that you’re the owner of your chosen payment method. We recommend that you upload the above documents immediately to save time. To ensure that everything goes smoothly, be sure to provide up-to-date information. In terms of processing times, some casinos can take up to 72 hours to verify your information, although it’s often a lot quicker. Much will depend on the documentation you provide and the individual operator.

Different Types of Online Slots
At most UK slots sites, there’s a large number of games for players to enjoy. They’re arranged into several categories to help people find what they’re looking for. There are a few broad categories that slots can be grouped into. For the benefit our our users we have provided basic summaries of the three main slot categories (classic, video and progressive) below.
Video Slots
Any slot that’s played on a screen-based device can be classed as a video slot because it uses video animations. At most UK slot sites, there are a few hundred or even several thousand of these games. The best slot sites have a large number of titles that come from a broad selection of providers. They offer everything from the newest releases to popular titles from recent years and lesser-known games.
Classic Slots
These are online slots that are inspired by early, physical slot machines. These games were very simple when compared with the slots that are being developed today. Most of them used a 3×3 grid with no special features. The gameplay was focused on landing enough winning symbols to get paid. While early physical games had limitations, online ones don’t. While some online versions of classic slot games strip everything back, others come with a few features (often quite basic ones) to make them more appealing to today’s players.
Progressive Jackpots
As explained in more detail, these are slots where there’s no upper limit on how much you can win. Instead, you can win a potentially unlimited sum of money. This is thanks to the progressive jackpot, a prize fund that keeps on growing until it’s won. The best slot sites have a good number of slots with progressive jackpots.
Understanding Progressive Jackpot Slots
There are two types of jackpot prizes: fixed and progressive. If it’s fixed, the jackpot prize is a certain multiple of your bet, e.g. 1,000x. As for progressive jackpots, they’re not based on your bet. Instead, they start at a set amount of money (the seed value) and grow in size whenever someone places a bet on the slot.
The way you win a progressive jackpot depends on the game you’re playing. For some, you can win the prize on any random spin, though the bigger your bet, the higher your chance of winning. For other jackpot slots, you could have to land certain symbols.
Some slots have more than one progressive jackpot. These games typically have a feature where you can win any of the jackpots. An example is a special wheel split into segments, with smaller progressive jackpots having more segments and bigger ones having fewer.
Mega Moolah
The most popular progressive jackpot slot is Mega Moolah from Games Global, so we’ll use that as an example. It’s themed to the wildlife of Africa and has been paying out life-changing sums of money since 2006. Mega Moolah has four progressive jackpots, each of which starts at a different value:
- Mini: £10
- Minor: £10
- Major: £10,000
- Mega: £1,000,000
On any random spin, the jackpot feature can trigger, with higher bets giving it a better chance of coming into play. This feature has a wheel with 20 segments:
- Mini: 10
- Minor: 6
- Major: 3
- Mega: 1
If this feature launches, you’ll have a 1/20 chance of landing the top prize, the Mega jackpot. Since this starts at £1,000,000, you’ll be a millionaire should you win it.
Mega Moolah is regarded as one of the best slots thanks to its incredibly high payouts. It’s been such a success that there are over two dozen games – most of them slots – that incorporate the four Mega Moolah progressive jackpots. The original and many of its spin-offs can be found at many slots sites in the UK.
Before playing a progressive jackpot slot, check the paytable to find out how much the prize fund starts at and how you can win it.
Popular Online Slot Themes
Visit any slots site and look through the collection of slot games. What you’ll notice is that there’s a wide variety of themes being used. Part of what makes slots so appealing is that there’s no limit to the themes they can have. The companies that make these games can be really inventive and creative when it comes to developing themes.
The best slots have a cohesive theme that’s well presented in the gameplay, symbols and special features. When a slot’s designed well, it can offer players an immersive and memorable gaming experience they’ll want to come back to. Below are summaries of some of the key themes that slots can have.
- Adventure. Slots with adventure themes are all about going on exciting travels, exploring new places and tracking down treasures. They’re set in locations all over the world and typically feature a main character on some sort of mission or quest. Gonzo’s Quest from NetEnt and Book of Dead from Play’n GO are some great examples.
- Fantasy. These slots immerse the player in imaginative, made-up worlds full of magical elements. they include mythical realms, legendary creatures and powerful people with special abilities. If you want to play some fantasy slots, check out Sweet Bonanza from Pragmatic Play and Avalon from Games Global.
- Classic. Some slots don’t have a creative theme as such and are instead designed to look like physical slot machines and early video slot machines. These games tend to have various fruits as symbols along with playing card ranks, BARs and number 7s. Play 777 Strike from Red Tiger Gaming or 27 Joker Fruits from SYNOT to see this type of slot in action.
- Sci-Fi. Another common theme you’ll find in slots is sci-fi, commonly associated with outer space exploration, time travel and how advanced technology may affect us now and in the future. Lots of the best UK slot sites have sci-fi slots; some of the top ones include Weird Science from Habanero and Machina Megaways Mini-Max from Kalamba Games.
- Animals. The number of slots featuring animals is huge. Some of them include animals that are imaginary or extinct (i.e. dinosaurs), while others focus on wild animals and pets. Buffalo Blitz from Playtech and Kawaii Kitty from BetSoft are two of our recommendations.
- Branded. At some slot sites, there are games that are based on existing IPs such as popular films, TV shows and celebrity brands – or even board games. These are known as branded slots and they’re developed by some providers to attract a broader range of players than slots based on original themes. If you’re keen to try out a branded slot, play Guns N’ Roses from NetEnt or Monopoly Megaways from Big Time Gaming.
At some slots sites, there’s a filter that lets you sort slots by theme. Others have sub-categories for certain themes. Many online slot sites, however, don’t have any sort of filter or category system that focuses on themes.
Online Slot Mechanics and Features
One of the best things about UK slots online is that they have all sorts of mechanics and features. Visit any of our recommended slots sites and you’ll find that the games vary greatly in how they work and what they have to offer. Below are summaries of some of the key aspects of slots.
RTP
Every online casino slot has an RTP. This term stands for ‘return to player’ and is displayed as a percentage, e.g. 96%. It refers to a game’s average expected payout over long-term play.
If you play a slot whose RTP is 96%, there’s a high chance you won’t end up getting this exact percentage of your money back. You could make a profit, win much less than you spend or even end up losing everything. The point is that RTP refers to long-term play. Therefore, the more you play a slot, the closer your average payout per spin should equal the slot’s RTP.
The higher a slot’s RTP is, the more it should pay you over the long run. However, there’s still a chance you could make less money than expected (or none at all) from a slot with a high payout rate. Likewise, you could have a few spins on a low-RTP slot and make a hefty profit from a lucky win.
For most slots, the RTP is 95% to 96%. If it’s any lower than 95%, you might want to consider playing another game instead. The best slots have an RTP of 97% or even higher, though such games are few and far between.
Volatility
Another key term to understand is volatility. This refers to two things: how often a slot pays out and how big the payouts are. There are three main levels of volatility:
- Low. If you play a low-volatility slot, you’ll probably win quite frequently, though the payouts will be on the smaller side.
- Medium. Slots with medium volatility give you a balance of small and big wins, while also giving you payouts at a fairly decent rate.
- High. With highly volatile slots, wins don’t come around too often, though when they do they tend to be significant.
If you’re a beginner or you’re on a budget, it’s best to play a slot whose volatility is low. Move up to medium-volatility games if you want a shot at earning some bigger payouts. You should play highly volatile slots if you’re prepared to take a risk and have the bankroll to fund your gaming.
In most slots, the volatility is fixed and can’t be changed. Lots of slots from Wazdan have a built-in feature that lets you switch between three volatility levels at any time.
Symbols
These are a key feature of slots because they determine whether you win or lose and they can trigger special features. Symbols are icons that appear on a slot’s grid. They’re usually designed to fit the theme. For example, if the theme is outer space, the symbols could be planets and stars.
In some slots, all the symbols match the theme. However, it’s common for some symbols (usually the low-paying ones), to be represented as playing card ranks (A, K, Q, J, 10 and 9, for example). A typical slot has several types of symbols.
Regular Symbols
These are the most common symbols you’ll come across. They give payouts when enough of them land in the right place, i.e. on a payline or in a cluster. A lot of the time, the pay table lists them as high-paying and low-paying (sometimes there are medium-paying symbols too). The exact amount of money you win depends on the symbol and how many instances of it there are on the payline or in the cluster. The more winning symbols there are, the bigger the payout.
Wilds
Wilds are great because they can help you win when you play UK slots online. What a wild does is it substitutes for all other regular symbols. When a wild lands, it will act as a particular symbol if doing so helps you win. It can act as more than one symbol at a time. This means you could get several winning combinations from a single wild.
There are several types of wilds you’ll come across when playing slots. Walking or moving wilds stay on the grid for multiple spins, moving one position with every spin until they’re off the screen. On the other hand, sticky wilds stay where they are for a set number of spins (they usually appear in a free spins round and remain in place until the round’s over).
Then there are expanding wilds, which grow in size until they fill the reel, boosting your chances of winning. You may also see multiplier wilds; they come with a multiplier value (e.g. x3) and multiply all winnings they help to create accordingly.
Scatters
A scatter is a special type of symbol that triggers a slot’s bonus feature; usually, this is the free spins round. In some slots, scatters only appear on certain reels; in others, they appear on all of them. Some scatters give payouts if enough of them are on screen.
However, unlike regular symbols, they ignore paylines. What this means is that they can appear anywhere and you’ll get paid so long as there are enough of them. Some slots pay you for getting just one scatter on screen; others only give you a win if there’s a minimum number of them.
Paylines
Slots have a grid that symbols appear on. Grids come in a range of shapes and sizes, though the most common set-up is three rows and five reels (columns), giving you a total of 15 symbols. A payline is a line running across the grid, covering one position per reel. To win, enough matching symbols have to land on a payline. They need to be on consecutive reels and must start on the leftmost reel.
This is the most common arrangement. Many slots do things differently. Some, for example, have paylines that run in both directions, so the line of matching symbols can start on the rightmost reel as well as the leftmost one.
Quite a few slots use the all-ways-win system. What this means is that every possible payline on the grid. The maximum number of paylines depends on how many rows and reels there are. If it’s a three-row, five-reel slot, the highest number of ways to win is 243. To get this number, you take the number of symbols on each reel and multiply them together, i.e. 3 x 3 x 3 x 3 x 3 = 243.
Other Ways of Winning
While most slots use paylines, some of them have different ways of winning. Cluster pays is quite a common mechanic. As its name suggests, this is where you win by forming clusters of matching symbols. The symbols have to be touching horizontally or vertically to count, and there needs to be a minimum number of them for the cluster to count. Some slots have a different system where you land enough matching symbols anywhere on the grid to win.
Bonus Rounds
In most slots, there’s a bonus round that you get to play when certain symbols appear. There are several types of bonus rounds: free spins, pick-me games and respins are among the most common. They’re designed to be exciting and encourage people to play; plus, they can be a lot more rewarding than the base game. To set them apart from the base game, they have special features and rules such as extra paylines, expanding symbols and multipliers.
Free Spins
Most of the best slots UK players enjoy have a free spins round. This works in the same way as the base game, except every spin is free of charge. There are usually some sort of special effects or enhancers in place. There could be a x3 multiplier that’s applied to all winnings or all of the low-paying symbols could be removed.
It’s common for you to need three scatters for a free spins round to come into play. In some slots, you’ll get more spins for more scatters on the screen, for example:
- Three Scatters = 10 Free Spins
- Four Scatters = 15 Free Spins
- Five Scatters = 25 Free Spins
The number of spins varies from one slot to the next. In lots of free spins rounds, scatters can still appear and if there are enough of them, you’ll earn extra spins.
Pick-Me Games
The pick-me game is a simple type of bonus round where you’re given a choice of options on screen. If it’s an underwater-themed slot, you could be asked to pick from a group of oysters, for example. Whatever you choose will then reveal a prize that’s added to your balance.
Some pick-me games have several parts, each with bigger prizes than the one before it. If your pick reveals the right symbol, you’ll move to the next part. However, there could be symbols that cause you to lose everything.
Respins
In some slot games, there’s a respin feature that gives you another shot at winning. What happens is certain symbols remain where they are while all others spin again for no additional cost. There’ll be a selection of new symbols on the reels and they could form new winning combinations.
There’s now a different kind of respin feature that’s quite common. This is where you get three respins with money symbols and blanks appearing. You keep getting the respins reset to three each time you get a new symbol, until no new money symbols appear. Once the round’s over, you’re paid all the prizes on the screen; these could include jackpots.
UK Online Slots Tournaments this week
There are several exciting UK slots online tournaments in which you can participate daily, weekly or monthly at the best UK casino and slots sites. These casinos provide a range of tournament options, appealing to different player preferences and enhancing the slot gaming experience with competitive rewards:

If you decide to join 32Red Casino, you’ll have access to lots of top games from leading providers and plenty of sports betting opportunities. You can also take part in not one, but two ongoing tournament series: Pragmatic Play’s Drops & Wins and Games Global’s Mystic Masters.

The collection offers slots, table games and live dealer games as well as bingo, Slingo, poker and more.
Enhancing Your Slot Tournament Experience
It is always worth remembering that slot tournaments are never going to be about skill – that’s just not how slot games work. You will be spinning the slots as usual during a tournament and either playing just for points, or you will achieve your normal wins from each spin but at the same time be earning points based on the level of the win.
This points collection system means that a slots tournament is open to everyone, whereas something like a poker tournament would need a decent level of knowledge about poker and its strategies.
Types of Slot Tournaments
When playing UK slots online you will find the two most common types of Slot Tournament are the ‘one-hit’ competitions and ‘fair-chance’ tournaments.
One Hit – this is where the tournament is open for a specified time and you are ranked on your highest single win over, say, a 20 consecutive spin session, with that win multiplied by your stake.
Fair Chance – where play is over a specified number of spins and your wins are divided by your stake, so everyone has the same chance of amassing a decent number of points.
The most common of these is the Pragmatic Play Drops and Wins Tournament with £2,000,000 given away every month and a daily prize pot of £40,000.
Top 5 Tips for Playing Online Slots in the UK
Playing online slot games can be a lot of fun. To help you make the most of your gaming experience, here are some useful tips to follow. Stick to these tips when you play slots at UK online casinos.
Read the Pay Table
Every slot has a pay table, which explains how to play the game and how everything works. It lists the symbols and their payouts and effects (if any), explains how to win and describes any special features there are. Bear in mind that some pay tables don’t tell you everything. For example, RTP and volatility are often omitted, so you would have to find these out elsewhere.
Before playing casino slots, check out the pay table and find out what the payouts and features are. The best online slots have a pay table that clearly explains everything. If something you need to know isn’t listed there, a quick online search should do the trick. Knowing as much as you can about a slot can help you decide whether it’s worth playing or not.
Play for Free Before Playing for Real Money
At some online slots sites, you can play demo versions of games for free once you’ve set up an account. Free play is great because it lets you get a preview of a game without having to pay a penny. If you come across a slot that you’re not sure about, play the demo version and see what it’s like.
Usually when you play UK slots online and choose the free slots option, you have a limited number of credits. If these run out, all you have to do is refresh the page and the credits will be restored. This means you can play demo slots as much as you like. We love this feature, but because of changing UK regulations we are finding that the option is disappearing.
Playing for free is great for testing things such as how often features trigger and how often you should win. It’s also useful for trying out paid extras (such as free spins rounds) to see if they’re worth purchasing. Remember that slots are luck-based games and that if you win big while playing for free, there’s no guarantee you’ll do the same when playing for real money.
Choose High RTP Slots
If you like to see bigger wins when they hit while online gambling, you should focus on slots that have a high RTP. Some of the best slots UK wise have an RTP of 97% or higher; ideally, you’ll focus on these if you can. Remember that you won’t be guaranteed better returns for playing slot games with better payout rates. However, if you only play high-RTP slots, you might stand a better chance of seeing those better returns in the long run.
Pick Slots That Have the Right Volatility for You
You should focus on slots whose volatility is suitable for your preferences and, of course, your budget. It may be tempting to play highly volatile games and try your luck for a big win, but the downside to these games is that they can be risky. You could end up sinking your money into the slot with little or no returns. Think about the volatility levels we mentioned earlier and see which sounds the best for you.
Keep Track of Your Budget
Whenever you gamble online for real money at slot sites, you should have a budget and stick to it. Casino games, including slots, are designed to encourage you to play and, more importantly, take money from you. Yes, you can make a profit, but doing this is the exception, not the norm.
To keep your spending in check, come up with a budget and make sure you’re only using money you can afford to lose. If you run out of money, that’s when you stop playing. The best approach is to treat gambling as a fun hobby and not expect to win.

slot sites faqs
Are online slots sites to be trusted?
You can if they are licensed. If you are in the UK, then make sure the site has a United Kingdom Gambling Commission licence. If you are not in the UK, then look out for licensing from a higher tier licensee, such as the Malta Gaming Authority, or the licence providers of Gibraltar or Alderney.
What’s the best strategy for playing online slots?
No. No matter what you might read on the internet, there is ‘no secret slots strategy that online casinos do not want you to know about’. Slots award wins randomly but are geared for the online casino to retain an advantage. If you do win playing online slots, it’s only down to luck and nothing more.
What will I win when I play slots?
Potentially, you could become a millionaire by playing online slots with progressive jackpots, but the odds of doing so are the same as the odds of winning a national lottery. Remember if you do win big, it’s only down to luck.
Are other casino games available at slot sites?
Most online slots sites will have casino games too, including live casino games. You should always be able to play blackjack and roulette at the very least, and some sites may have other games such as baccarat, casino poker and video poker.
Which is the best online slot site 2025?
That’s very much a matter of opinion most of the time! Everyone has different tastes, but the best online slots site are those with a high number of decent games, excellent support options, a range of newbie and ongoing bonuses plus a good range of options for deposting and withdrawing. What we can tell you is that Foxy Games was voted Best Slots Site in the 2023 WhichBingo Awards if that helps.
Can you name the slots site with the best odds?
No slots site can be considered as having ‘the best odds’. Each individual game has ‘odds’, or an RTP (return to player) as it is more properly known. Look for sites with a high number of slots with RTPs in excess of 95 percent.
Which slots give the biggest payouts?
Slots with high RTPS are the best paying slots, although there is no guarantee that any online slot will pay-out consistently. Looks for slots with RTPs in excess of 95 percent. Generally, the company NetEnt tends to produce slots with high RTPs, so look out for their games.
Are online video slots fixed?
Not at licensed online slots sites. All software companies MUST have their slots tested independently. Any company found to be operating ‘rigged’ slots risks a massive fine from the UKGC, as well as having their licence revoked. In short, it’s just not worth it.
Is it safe to play online slots?
While we should always be cautious about how we conduct ourselves online, there are very clearly defined steps that you can take to ensure that your experience playing online slots is as safe as possible. You’ve taken the perfect first step by checking out the sites featured on WhichBingo – we only feature UK licensed websites!
So, in a nutshell, only play at UK Gambling Commission regulated sites and be sure that any site you choose to play has adequate safe gambling tools for you to take advantage of should you want to limit your spend or time online.
We only ever review and recommend UKGC approved sites, but you can check a site’s status for yourself by taking a note of the registration number (usually located in the footer or on the About Us page) and then entering these details on the UKGC website. This will then confirm that a site is fully accredited and able to accept UK players.
Furthermore, the games at our recommended sites will also be independently audited and tested by third party agencies, such as eCogra, IGL or TST. Their role is to certify that the operation of games’ RNGs is fair, and to ensure that this information is easily accessible so that you can check it out for yourself.
A site should have clear and accessible policies in place with regard to responsible gambling. For instance, our featured sites all enable you to place limits on your deposits (either daily, weekly or monthly) or, if necessary, to voluntarily lock yourself out of your account for a pre-determined period of time.
Playing online slots should always be an exciting and enjoyable pastime, and that’s why we ensure that all of our featured sites have these sorts of mechanisms in place, so that your gaming experience is always a positive one.
Do high-ranking slots offer the highest RTP?
No, high-ranking slots do not necessarily offer the highest RTP. Return to Player (RTP) is a statistical measure of how much a slot machine pays back to players over time. While some high-ranking slots might have competitive RTPs, it’s not a strict rule. Players should always check the game’s specific RTP regardless of its ranking.
What could be the reason for potentially lower RTP in UK slots?
Complex and ever-changing regulations and taxes in the UK’s gambling industry can lead to lower RTP in slots. Operators must adhere to stringent rules to how they market the games and pay high taxes, including a 20% remote gaming duty on gross gaming yield. To compensate, some slots sites might reduce their RTP to maintain profitability within this harsh regulatory framework.
Do UK slot games differ from those in other nations?
Yes, UK slot games can differ from those in other nations due to regulatory requirements. The UK Gambling Commission enforces strict guidelines on game fairness, responsible gambling, and advertising. This can influence game design, features, and RTP to meet UK standards. For example UK slots can no longer include an auto-play feature, they must have a 2.5 second gap between spins and players cannot buy bonus features. These options will still be found on the same games when they are made available in other countries that follow different regulations.
