What should you look for in a slots site?

Fully licensed and regulated sites

The UK online gaming market is currently one of the most closely regulated in the world. Any site that offers online slots or casino games to players in the UK, or advertises online gambling services, is required to be licensed by the UK Gambling Commission. In order to be granted such a licence, an operator is required to fulfil a number of conditions with regard to fair play, customer privacy, and the prevention of underage or problem gambling.

Therefore, the slots sites UK players can access will offer a safe and secure gaming environment, while you also have the added satisfaction of knowing that there are complaint and redress procedures in place should something go wrong.

UK Gambling Commission regulation

We believe that player protection is a crucial component of a well-run slots site, which is why we only recommend casinos that are licensed by the UKGC. In addition, we also only feature sites that are accredited by the gambling authority of the jurisdiction from which they operate, such as the Malta Gaming Authority (MGA) or the Alderney Gambling Control Commission (AGCC).

Furthermore, our recommended sites will also be subject to testing and audit by an outside, third-party agency, such as eCogra or IGT. The role of these specialist agencies is to certify that the games on a site are being operated fairly e.g., the random number generators (RNG) are producing genuinely random spins, and any site we list here will enable you to have access to these test results so that you can see for yourself that you are getting fair play.

Good value bonuses and wagering requirements

For many players, the quality and value of any Welcome Bonus that is being offered can be the key factor in choosing to play at one particular slots site rather than another. However, signup offers can vary quite significantly from site to site, and there are a number of different varieties out there, so this can make choosing the right slots bonus a confusing task. To make it slightly easier for you, however, we only recommend sites where we think the signup bonus gives players some value and comes with reasonable wagering requirements.

When you’re looking at welcome bonuses, there are a number of factors you have to consider, such as the type of game you play most often, how regularly you play and the size of bankroll you typically maintain. Other questions you need to ask about any introductory offer include whether it’s made up of deposit matches or bonus spins (or a combination of both), as well as any other features included in the deal.

Signup bonus wagering requirements

With a slots signup bonus, you also need to look closely at the wagering requirements that are a part of the offer and how long you have to clear the bonus. The wagering requirement (also known as the playthrough) is the factor that determines when you are able to withdraw any of the cash you receive as part of the bonus, or any winnings you make from playing with the bonus.

The wagering requirement will be expressed as a multiple e.g., 30x, 40x, etc. This refers to the number of times you have to wager the bonus sum before you are deemed to have met the playthrough. For instance, if you receive a £100 welcome bonus with a 40x wagering requirement, you need to wager £4,000 (40 x £100) before you can cash out any of the £100 you received, or winnings made playing with that £100. If you do make a withdrawal before you clear the bonus, you will forfeit any remaining bonus as well as any bonus winnings you have accrued. You should also take note as to whether the wagering requirement applies only to the bonus sum, or whether it applies to your deposit plus the bonus amount.

Which games clear the bonus?

You also need to take note of which games contribute to clearing the bonus. At most new slot sites we feature here, online slots contribute to the playthrough 100% i.e., every £1 you wager on slots counts as £1 towards the playthrough. However, you need to be aware that this does not always apply to progressive jackpot slots, and that many other games will make a far smaller contribution, while some games will not count towards clearing the bonus at all.

For new players, please note that the wagering requirement refers to how much you have to wager before you can withdraw the bonus, and not how much you are required to lose.

The slots sites UK players tend to favour will offer a variety of different welcome bonuses:

No deposit bonus

A no deposit bonus is one that gives you a bonus — usually in the form of slot spins — when you sign up as a new player at a slots site but before you are required to make a real money deposit. These spins will usually be on a designated game (or games) and you can usually expect to pick up around 10 spins as part of a no deposit bonus (although the number will vary from site to site). In most instances, you will be able to continue playing with any winnings from your no deposit spins once you make a first deposit into your new account. Any subsequent winnings then made from these will then usually be subject to wagering requirements.

Deposit match bonus

A deposit match bonus is one of the most common signup deals on offer at UK slots sites. When you sign up as a new player and then make your initial deposit into your casino account, you receive a deposit match — this will usually be 100%, so your bankroll is effectively doubled i.e., if you deposit £100 with a 100% match bonus, your bankroll will automatically grow to £200. At many sites, you can also expect to receive additional match bonuses on subsequent deposits (often up to your first five), although the size of the match will usually be less than 100% on these deposits.

The wagering requirement attached to a deposit match bonus will vary considerably from site to site — currently, the best you can expect to receive is 30x, although at some slot sites it will be as high as 60x.

Free spin bonus

Free spins as part of a welcome bonus are becoming increasingly popular at our featured casinos. They are often attached to a deposit match bonus e.g., get a 100% match on your first deposit, plus 100 free spins. These spins will usually be on a selected game (or you may have a choice of games), with any winnings from these spins subject to the site’s standard wagering requirements.

As well as signup offers, once you open an account you can continue to take advantage of other types of bonus:

Cashback bonus

Some casino sites will give you cash back when you make deposits at specific times, and/or play specific slot games. With this sort of deal, you will receive back a percentage of any losses made when playing with the sum you deposit.

Refer-a-friend bonus

With a refer-a-friend bonus, if a mate you recommend signs up via a link you send them and then makes a first deposit into their new account, you receive a cash bonus (as does your friend). The amount will vary, but it can be as much as £50, and will usually be subject to wagering requirements.

Reload bonus

A regular promotion that the best slots sites offers is a reload bonus, where you receive a match bonus when you make a deposit on a particular day of the week. Generally speaking, this will be in the region of 10% – 25%, and winnings will be subject to a playthrough requirement.

VIP and high roller bonuses

Once you have been recognised as a high roller or achieve VIP status, you will frequently be rewarded with a range of bonuses. These may be in the form of deposit matches, free spins, or invitations to take part in exclusive promotions.

Games from a variety of software producers

The online gaming world is constantly evolving, and one of the most exciting developments has been the entry of many new game producers into the market. We particularly enjoy playing at sites where the games of multiple producers can be played, as this means you get greater gaming choice and variety.

At most of the sites we feature here, the producers will consist of a combination of the big name developers, like NetEnt, Microgaming and Playtech, along with slots by emerging game producers, such as Yggdrasil, Quickspin, Eyecon and NextGen Gaming, as well as new developers who are just beginning to make a name for themselves.

Playing at a site with a range of producers’ games means that you have a bigger selection of slots to choose from, with great variety in terms of themes, paylines and special features.

A variety of slot game styles

The slots sites UK players most enjoy are those that offer real gaming variety, with slot games in a range of categories. One of the most exciting features of today’s online casinos is that gaming boundaries are constantly being pushed, and this means that new game styles and features are frequently coming online so there is always plenty of new territory for the dedicated slots player to enjoy. However, this isn’t done at the expense of classic and well-loved games, so the best slots sites will feature a good mix of the best-known styles along with innovative games that break new ground.

3 reel slots

Also known as old-school or classic slots, 3 reel slots are the original version of the game but they still prove popular in online casinos today. This is largely because they offer relatively straightforward gameplay, featuring 1, 3 or 5 paylines, and a limited choice of coin sizes. 3 reel slots also tend to have fairly simple themes and an uncluttered look, especially when compared to more elaborate video slots.

5 reel slots

The vast majority of games that you’ll find at our featured casinos are 5 reel slots, but within this category you’ll find enormous gaming variety, along with a plethora of game styles and special features. You can play 5 reel slots with as few as 10 paylines or as many as 100, while the range of coin sizes means you can play for a few pence or hundred of pounds per spin. There is no limit to the themes and designs of 5 reel slots, and they often feature very imaginative special features and bonus rounds that add an extra dimension to your gaming.

243 and 1024 ways-to-win slots

An innovative style of game, 243 and 1024 ways-to-win slots don’t have paylines like most games; instead, a winning spin comes up when you hit 3 or more symbols on adjacent reels in any combination. 243 ways-to-win games have 3 rows of symbols, while there are 4 rows on 1024 ways-to-win games, and in both games 30 lines are generally considered as being automatically in play on every spin for wagering purposes.

Video themed slots

Probably the most popular type of game, video themed slots are based on well-known movies, TV shows, video games, bands and pop performers, and they recreate the characters, music, storylines snd themes from these other media.

For instance, you can play slots based on hit TV shows like Game of Thrones or The Sopranos, the biggest names in music like Guns N’ Roses and Jimi Hendrix, much-loved DC and Marvel Comics superheroes, video game icons like Lara Croft, or the biggest smash hit movies, such as Jurassic Park and Gladiator.

Progressive jackpot slots

Progressive jackpot slots give players the chance to win truly enormous jackpot payouts, sometimes running into millions of pounds. They are networked games where a proportion of every losing spin wherever the game is being played goes into the prize pool, so the potential jackpot grows very quickly. Most progressive jackpot slots have a minimum prize, and it’s re-set and begins to grow again whenever it’s won, while some games have different levels of jackpot prize.

The way in which the progressive jackpot is won varies — in some games it is randomly triggered, in others it’s won in a conventional manner by hitting 5x symbols on a payline, while some games award the jackpot in a special bonus round.

Slots with good RTPs

One of the advantages of playing online slots is that you get a better return to player percentage (RTP) than you do with land-based slot games. However, there is nevertheless quite a range when it comes to RTP, and when we review slot games, we always let you know what it is and how it compares to other similar games.

This is important to know because it significantly influences the gameplay. For instance, a low volatility slot will give you relatively frequent payouts, but they will be comparatively small, while a high volatility games doesn’t pay out too often, but the wins will be bigger. Therefore, the sort of the game you choose may well depend on whether you like fast and furious gameplay with lots of little wins, or a slower game with larger payouts.

A good selection of payment methods

One of the most important factors in choosing an online casino site is the accessibility and convenience of the payment methods on offer. A site may have a great range of games, but if depositing and withdrawing your money is a pain, there is no great incentive to signing up. This is why we only recommend slots sites UK players can use without too much difficulty.

The key to this is the range of payment options beyond credit/debit cards and direct bank transfer, which can be used at every site we feature. We think the best slots sites are those that offer a range of alternatives so that all bases are covered.

PayPal, e-wallets and Boku

For instance, we tend to favour casinos where you can use PayPal to make deposits and withdrawals, as it is not only convenient but also offers one of the quickest withdrawal times. This is also the case with e-wallets such as Skrill and Neteller, and although these aren’t universally accepted, you’ll find that a majority of the sites that we recommend will offer these. Increasingly, Boku deposit slots are gaining popularity at UK casinos, and this can be an extremely convenient way of making deposits; however, there are some distinct disadvantages to using it e.g., there is a daily limit as to how much you can deposit, and it’s not possible to use Boku for withdrawals.

Other payment methods that you’ll find at our recommended sites include pre-paid PaySafe Card and entropay, as well as ecoPayz e-wallets, and we’ll let you know in our reviews which of our featured sites accept these.

Fair withdrawal times

It has to be said that one of the most frustrating aspects of playing at an online casino is that the withdrawal times can be quite slow. At most of the sites that we recommend, you’ll find that any withdrawal request will be subject to a pending period before your payment is processed, and during which time your request can be cancelled. Once the pending period is over and your withdrawal is completed, your money will then arrive in your PayPal or e-wallet account within hours — however, if you withdraw to a credit or debit card it can take another 3 business days for your money to reach your account, while it may take up to 10 working days for you to get your money if you choose direct bank transfer as your withdrawal method.

Generally speaking, 48 hours is (or at least should be) the industry average for processing time. We think this is fair and reasonable, although there are a number of sites where it can take 3 working days or more. If this is the case, or thee are any other unusual restrictions on withdrawals, we will let you know in our review.

Fair withdrawal caps

All online casinos will place a cap on how much you can withdraw from your account (this is generally thought to be the result of money laundering laws). These restrictions may affect how much you can withdraw on a given day, within a week, or in a single transaction.

When we review a slots site, we will let you know what restrictions or caps are in place with regard to withdrawals. In most cases, these are reasonable and shouldn’t present too many issues for players, but if we think the withdrawal cap is not high enough, or doesn’t let you make withdrawals frequently enough, then we will make this clear.

Reliable customer service

The quality of the customer support you receive is an important factor when determining how enjoyable the playing experience is at a casino site. That’s why we place a strong emphasis in our reviews on how well players are looked after.

For instance, we look at all of the points of contact you have with customer support, such as email, phone support and live chat. We also give positive recommendations to sites who have a lively and active social media presence, so that you can connect with them in a greater number of ways.

How quickly do they reply?

We also place an emphasis on how quickly customer services reply to your queries and questions, and how helpful they are. We also let you know where the support team is based and how good their English communication skills are.

Another important element of the customer service a casino offers is the provision of FAQ pages, as well as clear and accessible privacy policies, so that you know how your personal data is being stored and used.

Slots sites with a good reputation

We only recommend reputable slots sites UK players can trust, so you can be sure that any online casino that we feature here will be a place where you can play safely and securely. However, there are some very clear signs as to how you can spot whether a site has a solid reputation and whether it is a reliable place to play or not.

Is it a licensed casino?

First of all, check that the site is licensed by the UK Gambling Commission. You will usually find this information in the footer on the home page, which will include a licence number that you can check. Likewise, there should be a clear indication of the jurisdiction from which the site operates, and there should be an easily accessible link to the relevant supporting documentation.

You should also be able to see which independent testing agency audits the games on the site, and be able to access the overall RTP rates of its slots and casino games. If you can’t see this information, or you can’t access it, then you are well within your rights to be suspicious of a site’s bona fides.

Privacy policies

A reputable online casino site will also have clear policies in place with regard to your privacy, and how your personal and financial data is handled. If these aren’t easily accessible, the site is likely not one that you can trust and you should think carefully about sharing any private data or banking details.

In terms of the gaming on offer, you can tell a lot about a casino’s reputation by the developers whose games are on the site. That’s why we only recommend casino sites with slots by leading software developers, such as Microgaming, NetEnt and Playtech. These producers only licence their games to sites that are well-run and operate a secure gaming environment, so always look at the games that are offered before you sign up at a slots site.

How to spot a rogue slot site

Despite online gaming in the UK being regulated, there are nevertheless some rogue online casinos out there who you should naturally avoid. Of course, we only feature and recommend top slot sites that are well run and offer a safe and fair place to play, but it is nevertheless useful to be aware of what to look for when you are trying to spot a rogue or blacklisted casino site.

Bogus accreditation

The use of bogus licensing and accreditation is one of the most common ruses employed by rogue casino operators. They either post fake licensing details e.g., they say they are regulated by the UK Gambling Commission but they are not, or they operate out of a jurisdiction that does not have a thorough or properly-run accreditation scheme. The majority of the sites that we feature here will be licensed by the Malta Gaming Authority, the Guernsey Casino Gambling Control Commission, or the Alderney Gambling Control Commission, as these are well-respected and trusted online gambling authorities.

In order to ascertain whether a site’s credentials are genuine, your first step should be to check the licence register on the UK Gambling Commission website. You can do this using either the UKGC licence number that is usually found in the casino site’s footer, or the casino operator’s business name. If you want to check whether a site is genuinely being regulated by a gaming authority, the authority’s logo should be featured on the site, and this should link to the registration documentation. If this isn’t accessible — or worse, doesn’t exist — then this is likely to be a rogue site and one you should avoid.

Slow payments

Rouge slot sites are also notorious for slow payments or withholding winnings. We always recommend that you check a site’s T&Cs with regard to their payout times, and the conditions you need to fulfil before you can cash out. If these aren’t clear or accessible, or they don’t exist, then you should be very wary of such a site.

Third party testing and auditing

You should also take care before signing up to play at a casino where there is no third party auditing or testing. If a site’s games are checked by an outside agency like eCogra, IGL or TST, then their documentation should be accessible from the casino site so that you can check that RNGs are operating fairly and the RTP percentages of each category of game. Some rogue sites will put a fake logo on their site to try and make you think that they undergo auditing, but if you can’t link directly to test results, then it us unlikely that the site’s claims of being audited are genuine and you should avoid playing there.

Poor customer support

Blacklisted casino sites will also provide very few methods for getting in touch or making a complaint — if any. Before you sign up at a casino site, check that there are multiple means of contacting customer support e.g., phone, email, live chat, etc. If you have doubts about a site, you should try a test message to customer support to see how quickly you get a response and whether they are able to answer your questions satisfactorily. Opt out options In line with the regulations laid down by the UK Gambling Commission, the best slots sites will offer players the opportunity to limit or reduce the amount they play, or the sums they deposit into their accounts, if they feel this is necessary.

Self-exclusion

If at any time you feel that you need to take a break from playing but have difficulty in doing so, there are some measures you can take at the sites that we recommend. For instance, you can choose to lock yourself out of your account for a set period, meaning you can’t log in and play for a length of time that you determine for yourself. This may be for as little as 24 hours, or it can be for a longer period.

Another way in which you can reduce how long or how often you play is by limiting the amount you can deposit into your casino account. You can set a 24 hour limit or a weekly limit, and this means you are unable to add any cash to your account during this period in order to reduce your potential losses.
