Top 5 Tips for Choosing the Best Slot Site

With so many options to choose from, selecting a new slots site can be a potentially confusing and time-consuming business. However, our team of reviewers has 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 slots sites to play at.

1)   Know your favourite game styles and studios

In our experience, choosing an online casino or slots site is easier when you have a clear understanding of the types of games you most enjoy, as well as which studios produce them. While our recommended slots sites will generally have a good mixture of game styles on offer by a variety of developers, knowing the sorts of games that work best for you will make it always make easier to choose a place to play.

For instance, if you have more conventional playing tastes, you will want to look for sites that have a good selection of classic slots that may be a 3 x 3 or 5×3 layout with a limited number of paylines. If you go for more extreme action, look for sites that feature slots where the gameplay is never the same for two spins in a row and where you have a huge number of potential payouts, as you get in games such as the Big Time Gaming licensed Megaways games, or the new variation of this revolutionary mechanic in the Megaclusters games. On the other hand, you might prefer games where the focus is much more on the bonus rounds and special features than on the base play.

Check out our Slot Game Providers page for more details as to who may be producing your favourite type of game and our Slot Games page for even more info.

2) Quality of the mobile slot sites

While it was once the case that mobile casinos were something of an afterthought, no operator today can survive without a high-quality mobile slots site. In fact, the emphasis has shifted to such as extent that a growing number of operators now focus their attention almost solely on their mobile gaming offerings.

All of the slot sites that we feature here offer mobile play, but sites can be of varying quality in terms of the UI, ease of navigation, and overall design and usability. Therefore, it pays to check out a site’s mobile design and how it looks on your particular device before you sign up at a new casino.

3)   Is the Welcome Bonus right for you?

Welcome bonuses at UK slot sites (and how they are described and advertised) have changed significantly since regulation of the industry by the UK Gambling Commission began. For instance, the bonus amounts you can get when you sign up at a new site are generally lower than they used to be, and there are fewer no deposit free spin offers around. However, there are still plenty of deals at the sites we feature here, and these offer varying degrees of value. This means it is definitely worth your while to check out the quality of the signup deal before committing to a new site.

Important features to consider include the wagering requirement, where you need to look at the rate (e.g., 40x, 50x, 60x, etc.), whether it applies to your bonus only or your deposit as well, and which slot games help you meet the playthrough. If free spins are part of the deal, check out whether the winnings come with wagering requirements and if they are cashable.

You should also take note of the maximum conversion amount, which essentially means the amount of bonus winnings you are able to convert to real money and then withdraw. This can have a big impact on the overall value of any introductory offer.

4)   Is there a good selection of other games?

Although we all love slots, some players like to mix it up with other games, like classic casino table games, video poker, or live dealer games. Just as many of the bingo sites that we feature here offer slots in addition to bingo rooms, most online slot sites will also have a range of other games. The number and range of these games will vary, but you will generally have a choice of table and card games alongside slots.

However, there are some sites that we feature here where slots are more or less the only game in town. Some might have a couple of standard blackjack or roulette games, or no table games at all (including no live dealer games), so if you spend any time playing live dealer baccarat for instance, or you enjoy video poker, then make sure the slots sites you choose give you the chance to play these games as well.

5)   Can you deposit and withdraw quickly and easily?

As we all know, the ways of funding your account at a UK slots site have significantly changed. This is why the number and range of banking options a casino offers have become increasingly important. Most of the slot sites that we feature here will offer safe and secure payment methods in addition to Visa and MasterCard debit cards, such as Pay by Mobile, PayPal, ApplePay, e-wallets and prepaid cards like Paysafecard. Any site that you are considering playing at should ideally offer one or two payment methods that are convenient and easily accessible for you. You will find that if you have a Visa debit card many sites will offer you Faster Payment and that means you will get your money within 3 hours and often even quicker.

We also recommend that you upload your ID and other relevant ‘Know Your Customer’ required documentation as soon as you join a site even if they don’t immediately ask for it – this means that come your first withdrawal there will be no delays.

6) Payment Methods and Policies

The majority of our featured sites accept PayPal and PaysafeCard, or enable you to Pay By Phone, so that any deposit you make into your online casino account is added to your monthly mobile phone bill (or deducted from your pre-paid balance).

The advantage of these forms of payment method is that you are not required to share any of your personal or financial information, such as debit card or bank account numbers, with your casino. This means there is one less place where your vital information is being stored, reducing the risk of being hacked or having your identity stolen.

In addition, most online casinos will also offer a number of e-wallet options, such as SkrillNeteller or ecoPayz, which are among the most secure ways of making online payments. What you will have to watch out for is that in many cases using these payment methods will exclude you from claiming any welcome offer that is advertised, so check the terms and conditions carefully.

We are also seeing a growth in sites accepting ApplePay and GooglePay.

They should also make clear whether there are any fees for making deposits and withdrawals, the length of time it takes to get your money out, and the sort of ID you have to be able to provide before you can cash out. If you want fast withdrawals then debit cards are the method for you. Nowadays, many online bingo and slots sites developed faster payment policies, especially for debit card users, enabling withdrawals to be completed in just a couple of hours instead of days.

How we rate the best slot sites

We take reviewing casino sites very seriously, and our experience means that we understand as well as anyone what make a site worth playing at — as well as what doesn’t.

We take a number of factors into consideration before recommending a site. First, we look at the value of the welcome bonus, including the wagering requirement, how long you have to clear the bonus, and the maximum conversion amount. Then we complete a thorough overview of the game selection, noting the most popular slots and game categories, as well as the other games on offer, like live dealer games, video poker and bingo. Our reviews also cover the quality of the customer support, the accessibility of the banking options, and how easy it is to play on a mobile device.

New sites come online regularly and we always review them as soon as they launch, so it pays to check back here regularly so you always have the most up-to-date information.

How are UK slot sites created?

Like the online bingo world, when it comes to slots UK players have an ever-increasing array of choices. A quick look at what goes on behind the scenes in the iGaming industry will help to explain why today’s players have so many gaming options.

When you sit down to play at your favourite UK slot sites, you might not appreciate the many different steps that are required to get these games onto your screen. However, it is always helpful for players to understand how the industry works, and all of the different elements that go into producing online slot games.

Essentially, there are three different sectors in the online gaming industry who each have different roles in the delivery of games to players:

  • Software developers — the studios that create, develop and produce games
  • Platform providers — the businesses that supply the games to slot site operators
  • Slot sites — the operators or brands where you play games online

In broad terms, what this means is that when you play at a UK slots site, you are taking part in a collaborative exercise rather than playing at a standalone site where everything is done by a single operator.

What is the role of UK slot sites?

The role of UK slot sites is to host an online space where you are able to play games, and who provide players with other services such as welcome bonuses, gamification features, customer support and more.

However, there are different categories of sites, with the most common being what are known as white label slot sites.

What is a white label slots site?

A white label slots site is one where an operator or brand buys or leases an entire online casino package from a platform provider, and then rebrands it under its own name. The package will generally include the games themselves (usually from a range of different developers and studios), as well as back-up support and other features.

The advantage for a casino operator in entering into a white label agreement is that it’s able to launch a new casino in a relatively short space of time and without the need to have its own in-house developers or infrastructure. Their focus can therefore be on the player experience instead.

For players, one of the biggest advantages of playing at a white label site is the variety of games you have to choose from. Most platform providers will offer games from a wide range of producers in their package, including both major names and emerging studios, so you get plenty of variety when it comes to themes, special features and gameplay styles.

In addition, as operators of white label sites are not concerned with game development or how they are operated, they can focus more on the player experience. As online gaming is an extremely competitive industry, slot site operators fight hard to attract and retain players, and so this can mean a much better all-round gaming experience, including better deals and bonuses.

White label gaming sites will also have multiple levels of regulation. In order to be a platform provider, licensing by the UK Gambling Commission is a prerequisite, while the slots site operator will also need UKGC approval as well as accreditation from the gambling authority of the jurisdiction in which they operate. This means that playing at a white label UK slot site should always be a safe and secure gaming experience.

Why play 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. The best sites featuring slots will offer a wide variety of games in a range of categories, including video slots, themed slots and progressive jackpot games, meaning you always have plenty of choice as to the sort of games you can play.

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

One of the biggest advantages to playing online slots is that at all of the sites that we feature here, both new and existing players can take advantage of a wide range of bonuses and rewards as an incentive for choosing one site over another. 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.

Exceptional choice and variety

Online gaming is an ever-growing industry, with more new casinos coming online all the time and new studios moving into slot game production. For slot players, this means that we have extraordinary choice and variety, both in terms of where we can play and the huge range of games to choose from. Online slots take a myriad of forms, and 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.

Enjoy a better 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.

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 2023?

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.

CONCLUSION

As the above demonstrates, there is a lot more to playing slots online than may at first appear! We are here to help you not only find the best online slots UK players can enjoy, but also the best sites to play them at.
