What are slots sites?

To put it simply, slots sites are online pages where you can find a wealth of slots games to choose from. Generally, you can play for fun with a demo version or get the real thrill of playing reel games with real money. A genuine slots site will be a legitimate place for you to play reel games and is authorised by established gambling regulators like the UK Gambling Commission. Be aware of rogue websites that pose as slots sites to collect your information for fraudulent activities. Make sure you only play at legal and valid slots sites like any of the ones in our recommended list.

Why play slots online?

Slot 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 online 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.

What sort of online slots can I play?

No matter what your gaming tastes are, there will be an online slot game that delivers. The range and variety of titles is enormous and growing all the time, and our recommended slot sites feature a huge range of games in all categories.

Classic slots

Fruit Fiesta Online SlotClassic slots, sometimes referred to as old-school slots, are those based on the original Las Vegas slot machine model i.e., usually 3 reels and 1 payline. There are classic slots that maintain this sort of traditional gameplay, like Jackpot Express from Microgaming, but there are also old-school online slots that incorporate more contemporary features at the same time, like Grand Spinn from NetEnt.

Pub slots

Da Vinci Diamonds Slot OnlinePub slots are generally a variation on the classic slot that also incorporate features from the traditional pub fruit machine, like nudge and hold. These slots can’t be played at all online casinos, but they do remain popular, especially games like Microgaming’s Couch Potato.

Another variation of the pub slot is the Scandinavian style slot game, that will also include the nudge feature but may also have other unique features, such as two sets of reels and a bonus game in the form of a Supermeter, like Super Nudge 6000 by NetEnt.

Video slots

Starburst Slot ReviewVideo slots is a broad, wide ranging category that can be used to encompass most online slots today. Essentially it refers to any sort of 5-reel slot game that features animation, and video slots are produced by all the major and emerging online slot studios. All of the most popular and well-known online slot games could be classified as video slots, such as Starburst, Thunderstruck, Esqueleto Explosivo and Easter Island.

Multiline slots

Raging Rhino Megaways SlotMost contemporary online slots today are multiline games i.e., they have more than one payline. However, this broad category encompasses a wide range of game styles. You can play slots with anywhere between 1 to 100 paylines, win-both-ways games (where the paylines run both left-to-right and right-to-left), and ways-to-win games, which don’t have paylines at all but instead pay out when you hit three or more symbols left to right on adjacent reels in any combination. Check out Immortal Romance for one of the most popular examples of a ways-to-win game.

Another new variation on multiline slot games is the Megaways game, where the number of reels and rows in play can change on every spin, and you can have as many as 117,649 ways-to-win in play at any time. Raging Rhino is a good example of a slot games featuring Megaways gameplay and payouts.

3D slots

Gonzo’s Quest SlotThe development of 3D games has been one of the most exciting innovations in online slots, taking the themes, artwork and design of games to new levels. The production values on 3D slots are especially high and give slots a look and feel that rivals that of the best video games. Some of the most popular and best-known 3D slots include Gonzo’s Quest and Jack and the Beanstalk by NetEnt, and Microgaming’s Jurassic Park.

Progressive jackpot slots

Mega Moolah SlotFor players looking for huge, life-changing jackpots then progressive jackpot slots are the game to play. These slots are networked, meaning that there is a central prize pool where a percentage of every losing spin goes into the jackpot wherever the game is played in the world. As a consequence, the jackpot can grow very quickly to enormous amounts, often worth tens of millions of pounds. There is a range of different progressive jackpot networks and games, with the biggest and most popular jackpot slots being Mega Moolah by Microgaming and Mega Fortune by NetEnt.

Flat top slots

Planet of the Apes Online SlotAny slot that isn’t a progressive jackpot game can be regarded as a flat top slot i.e., there is a maximum payout that can be won. The payouts on flat top slots varies hugely, and is generally dependent on the coin size, the number of paylines, and the number of coins than can be played per line. Some of the most popular and biggest paying flat top slots include Planet of the Apes, Phantom of the Opera and Epic Journey.

What is RTP and how does it work?

Anyone who has played slots or at an online casino will have come across the term RTP. This stands for return to player percentage, which is the amount (expressed as a percentage) that you can expect to receive back after playing the game for an extended period of time. For instance, if a game has a 95% RTP, if you play over a long period of time and wager £1,000, in theory you should end up with a bankroll of £950. In a sense, RTP is another way of expressing the House Edge, so a game with a 95% RTP has an effective House Edge of 5%.

It needs to be remembered, however, that this is a theoretical calculation and the RTP is unlikely to reflect any individual’s wins and/or losses when playing the game. This is because online slots games are games of chance that are operated using a random number generator (RNG), and the outcome any spin cannot therefore be predicted or influenced. The RTP also excludes major jackpot payouts, so the actual RTP you experience may be higher or lower than the theoretical rate.

The RTP on some of the most popular slots is shown below:

Cleopatra (IGT)95.02%
Gonzo’s Quest (NetEnt)96%
Starburst (NetEnt)96.1%
Mega Moolah (Microgaming)88.12%
Fluffy Favourites (Eyecon)95.3%
Rainbow Riches (Barcrest)95%
Bonanza (Big Time Gaming)96%
Around the Reels in 80 Wilds (Gamesys)95.77%

Is it safe to play online slots?

If you don’t have any experience of online gaming or slots, it’s perhaps understandable if you are somewhat hesitant and have some reservations as to whether it’s a safe and secure pastime. 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.

Only play at regulated sites

One of the best ways to ensure that you are playing online slots safely is only to play at sites that are accredited by the UK Gambling Commission. This is the government body that regulates all forms of online gambling in the UK, and it is only legal for UK players to play at sites that are UKGC accredited.

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.

For your own safety, we would never recommend playing at a slots site that is not accredited by the UK Gambling Commission.

In addition, all of the sites that we feature here are operated out of jurisdictions with well-established snd reputable online gaming authorities, such as the Malta Gaming Authority, the Guernsey Casino Gambling Control Commission, or the Alderney Gambling Control Commission. Sites operated from within these jurisdictions provide players with a safe and secure gaming experience, as the casino’s activities and operations are closely regulated.

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.

Safe and secure payment methods

For many players, being able to make secure online payments is one of the main areas of concern when it comes to playing online slots. This is why we only recommend online slots sites that give players a choice of secure banking options.

For instance, that majority of our featured sites accept PayPal and Paysafe Card, 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 credit 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.

Problem gambling policies

Another important factor that determines whether or not we recommend an online casino is their having clear and accessible policies in place with regard to problem 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, but we recognise that at times some players need a little help to ensure that their playing remains under control. 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.

How to choose a slots site

There’s an enormous number of slots sites on the internet so finding the best one to put your hard-earned money into could be a challenging and overwhelming task.
