Guide to Choosing the Best Slot Site

With so many options to choose from (including unique Slingo games which mix together both slots and bingo), selecting a reliable new slots site can be a potentially confusing and time-consuming business. However, Editor Nic 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.

Reasons Why You Should Choose UK Online Slot Sites

We classify anywhere you can play online slots as a slots site. Both online casinos and bingo sites feature slots, so we consider both of these to be in this category. Playing slots online is a fun way to the pass the time and possibly win some money – as long as it is done responsibly. Convenience plays a part too, you don’t need access to a land-based casino in order to enjoy spinning reels.

1. 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 free spins no deposit — 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.

2. 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.

3. 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.

4. 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.

What is RTP?

5. Safety

If a slots or casino site is UK registered then your money is in safe hands.

Every site on WhichBingo is licensed and regulated by the UK Gambling Commission, so you can be assured of having a safe and secure online gaming experience.

UK sites have to meet strict rules and regulations to ensure you are treated fairly and that the games are all monitored and by governing bodies, including the UK Gambling Commission, 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 services such as welcome bonuses, gamification features, customer support and more.

How 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.

What Are KYC (Know Your Customer) Requirements?

KYC is the process of verifying your identity. If you don’t do this you won’t be able to play games or possibly withdraw funds.

The process may differ between casinos, but most likely you will 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.

*TIP: 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.

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.

1. 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.

2. 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.

3. Progressive Jackpot Slots

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.

Deep Dive:

Understanding Progressive Jackpot Slots

There are two types of jackpot prizes: fixed and progressive.

Fixed jackpots: the prize is a certain multiple of your bet, e.g. 1,000x.
Progressive jackpots: 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.

How to win a progressive jackpot:

On some slot games you can win the prize on any random spin. For other jackpot slots, you have to land certain symbols.

Some online slot games 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 prize wheel split into segments, with smaller progressive jackpots having more segments and bigger ones having fewer.

Mega Moolah

The most popular progressive jackpot slot games is Mega Moolah from Games Global. It’s themed to the wildlife of Africa and has been paying out huge 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.

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.

1. RTP – What is RTP?

RTP stands for ‘return to player‘ and is displayed as a percentage, e.g. 96%. It refers to an online slot game’s average expected payout over long-term play (across thousands of spins).

To put it simply; if a slot’s RTP is 96% then on average you would expect to get £96 back if you bet £100.

However, 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 less than you spend, or even lose everything.

The higher a slot’s RTP is, the more it will pay 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.

2. 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.

3. 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.

4. 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.

5. 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

Each week we seek out the best UK slots sites and review a range of slots tournaments to give you a quick summary of all their most important features. There are several top UK slot sites with exciting online tournaments that you can participate in daily, weekly or monthly, to enhance your slot gaming experience with competitive rewards.

Smooth Spins Casino – Pragmatic Play’s Drops & Wins

There are lots of UK casino sites hosting Pragmatic Play’s Drops & Wins slot tournaments and Smooth Spins Casino is one of them. Spin the reels of selected slot games and collect points to work your way up the leader board and win a share of the prize pool. If you’re lucky, you could win a random cash prize along the way. Smooth Spins Casino has a large number of promotions, including many giveaways and competitions, so there are plenty of reasons to sign up. The casino’s large and varied collection of games is another reason.

Buzz Casino – Drops & Wins tournaments

Another casino site that hosts the Drops & Wins tournaments is Buzz Casino. Here you can participate in some of the most popular slot tournaments around. While the Buzz brand is mostly known for its many bingo halls throughout the UK, its website has a casino section with plenty of games to satisfy casino players. Lots of payment methods can be used here and deposits as little as £5 are accepted, which is great for anyone who’s trying to keep their spending low. As well as Drops & Wins, Buzz Casino has promotions giving out various rewards such as bonus money and free spins.

Play Jango Casino – slot tournaments

If you sign up at Play Jango Casino, you’ll get to take part in the casino’s very own slot tournaments. Some of them are free to enter and others require a small fee. All of them are fun, exciting and unpredictable. Join in and you’ll have a great time playing slots and trying your best to qualify for a prize. The tournaments take place throughout the day and give out free spins as prizes. Play Jango is an excellent choice for anyone after an online casino thanks to its large collection of around 3,000 games, its many promotions, its user-friendly site design and its many accepted payment methods.

Rainbow Riches Casino – Slot Masters

Unlike other online casinos, Rainbow Riches Casino is currently hosting two major slot tournaments, not just one. These are Drops & Wins from Pragmatic Play and Slot Masters from Blueprint Gaming. Both of these are well worth joining as they give you the chance to win prizes and have fun playing slots along the way. Rainbow Riches Casino is loosely based on the Rainbow Riches slot series from Blueprint Gaming. While these slots are available here, the casino has loads more games you’ll want to check out. Some of its other advantages include quite fast withdrawals for some payment methods, 24/7 live chat and a long list of Safe Play tools.

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 Slot Game Providers in the UK

Who are the companies that make slots? What’s the difference between slot providers? And does it matter?

Slot sites like Gala Spins and Bet365 Games don’t make games themselves, they rely on other companies called providers or developers. These developers supply games to multiple slot sites. So that’s why you’ll find your favourite slots and classic games on multiple different slot sites.

There are a lot of different slot providers, and they each differ in quality, style, and features.

If you’re playing the most popular online slots, they’ve probably been made by one of these companies:

1. Blueprint

Notable Games: Fishin’ Frenzy, The Goonies, Deal or No Deal
Best Known for: Megaways slots, jackpots, pop culture themes

2. NetEnt

Notable Games: Starburst, Gonzo’s Quest, Narcos
Best Known for: High RTP slots, visual polish

3. Pragmatic Play

Notable Games: Gates of Olympus, Big Bass Bonanza
Best Known for: Megaways slots, Drops & Wins Tournaments

4. Games Global

Notable Games: Mega Moolah, Immortal Romance, 9 Masks of Fire
Best Known for: Progressive jackpot slot games

5. Playtech

Notable Games: Age of the Gods, Breaking Bad, Grease, The Walking Dead
Best Known for: Official movie and tv slots

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.

Click to learn more:

1 – 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.

2 – Try Demos Before Playing with 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.

3 – Choose Slot Games with High RTP

If you want a better chance at a payout, you should focus on slots that have a high RTP. What is 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.

4 – Know What Slot Volatility Is and Pick Slots That Match Your Style

Slot volatility is how often a slot game pays out. A high-volatility slot will pay out less often, but in larger amounts. A low-volatility slot pays out more often but with smaller amounts.

You should pick a slot game with volatility that suits 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.

5 – Set a Budget and Stick to It

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.

Jaws of Fortune Slot Review

It’s time to sink your teeth into some potential big cash prizes spinning the reels of Stakelogic’s Jaws of Fortune! Players will be transported into crystal blue waters off the coast of a beautiful tropical island. Symbols on the 5 reels with 1,024 ways to win include a shark tooth, bottles of beer, scuba mask, oxygen tank, surfboard, shark fin wild and gold bonus coin.

When the shark symbol lands on the second, third and fourth reels, respins are triggered. The shark symbols become sticky wilds during this round. Jet ski symbols can also trigger respins when they land on reel 5 and will become sticky. Another fun feature is the shark attack feature which is triggered when the shark and jet ski symbols land simultaneously. The shark symbols become roaming wilds and head towards the jet ski, leaving wilds as it swims. Once it reaches the jet ski, it grabs its prey and replaces it with another wild. Other shark wild symbols can then follow and move across the screen. If they move over another wild symbol, its value increases by 2x. Once all the shark attacks end, the round finishes. Finally, there is the hold n win feature which is triggered by landing gold bonus coins on reels 1, 3 and 5. Players are awarded 3 respins with only coins, sharks and jet sky symbols on the reels. Whenever these symbols land, they become sticky on the reels and the respins reset. Again, players can watch as the shark heads towards the jet ski, leaving cash values as it swims plus it may have a multiplier attached of up to 5x. Jet ski symbols can potentially add values of up to 10x to 3 random bonus coins. All coin symbols have a value attached of between 1x and 50x and at the end of the round, the values will be awarded. The round only ends when the entire screen is filled with coins or there are no more respins.

The minimum bet per spin in Jaws of Fortune is 20p and the max win potentially up for grabs is 5,000x your stake. Play this game at BetMGM Casino.

Age of the Gods: Gold Trio Slot Review

Age of the Gods is one of the most successful series of slot games available anywhere online and it is back once again in Age of the Gods: Gold Trio! In this Playtech slot, the Greek mythology theme is back once again and symbols on the 5 reels and 30 paylines include flowers, wheat, grapes, pomegranate, apples and a golden wild.

The highlight of Age of the Gods: Gold Trio is the coloured coins which are purple, red, blue and a sun. The sun only appears in a designated Hot Zone on reel 3. When coloured coins land, the matching goddess energy ball can grow and potentially trigger the Gold Trio Respins. Watch out for cash prize coin symbols landing with a number on them as this is awarded as a multiplier of your total bet up to a maximum of 5x. Then, we have the mystery prizes. If the sun coin symbol lands in the hot zone during the Gold Trio respins, a second reel grid is unlocked to award a mystery prize of a mini, minor or major jackpot of up to 50x. This prize is awarded randomly. Finally, there is the Gold Trio respins which triggers randomly when a coloured coin lands. The triggering colour of the coin then locks on the main reel set. 3 respins are awarded with 5 coins on the main reels. If the second sun coin hot zone grid is activated, 3 coins appear there. Special features associated with the coloured coin can trigger including mystery prizes, random cash prizes, coin values doubled and instant payouts of all current coins on the reels. Whenever a new coin symbol lands on the reels, the respins reset to 3. The feature ends when the respins finish or the reels are filled with coins.

The minimum bet per spin in Age of the Gods: Gold Trio is 20p and the maximum win potentially up for grabs is 2,000x your stake. Play this game at Heart Bingo.

Super Flip Deluxe Slot Review

Super Flip Deluxe is a fun, retro themed slot game from the developers at Play’n GO. This slot has a classic feel to it with a funky backdrop and the reels set within what looks like a real life slot machine. On the 5 reels and 20 paylines, a wide variety of high value symbols can be found including gold stars, four leaf clovers, diamonds, strawberries and horseshoes, while the low value symbols are the standard playing card symbols. There is also a WILD symbol and a game logo scatter symbol.

Watch out for symbols landing with a token as these can provide an instant win of between 10x and 1,000x. If a stack of matching symbols land on reels 1 and 2 but no wins land, then a smart repin triggers. Reels 3, 4 and 5 then spin one after the other if there are no wins formed on them. Finally, there is the free spins bonus round which triggers by landing 3 or more scatter symbols on the reels. Players are then awarded 15 free spins plus an instant payout of between 2.5x and 10x, depending on the number of triggering scatter symbols. The reels flip to reverse the reel order during this feature to help potentially provide bigger wins. This round provides the potential to get up to 175 free spins.
