Popular UK Slots

Whilst there are thousands of top-quality new slot machines online, there are still plenty of older games that are beloved by many in the UK. Some games, which are nearly a decade old, like Starburst, Twin Spin, Reel Rush and Gonzo's Quest, are still designed the very same way as they were all that time ago (nothing has changed) and are still as popular today as they were when they were first launched. Whilst they might not boast some of the newer slot features you see in newer slots, they are still popular due to their theme, design, soundtrack and simplistic features. Even if some of these online slots are "first-generation" games, it's great to see that their game developers have left these slots well alone, with a clear "if it ain't broke don't fix it" mantra.

There are plenty of huge progressive jackpots available at new slot sites, with notorious Mega Moolah, Mega Fortune, Hall of Gods and Imperial riches being the favourites. The best new slot sites offer over 50 progressive jackpot slots, with varying jackpot amounts, ranging from several thousand to several million!

How We Review Slots

As slot experts, we aim to cover every detail of a game in our slot reviews so that you can learn about all aspects of the game, no matter how tiny they are there or insignificant they may sound. We aim to provide you with the information to pick the right online slot. How’s a little bit about how we review slots online:

Slot Providers/Developers

We only review games by reputable software providers which offer fair and top-quality slot games. There are hundreds of slot game developers to choose from, some hugely popular and some lesser-known, though we like to think that they each bring something different to the table. Most likely, you have a favourite slots vendor like we do; however, it's fair to say that our list of favourites has grown over the past couple of years because many of the game studios are becoming leaders as each has something individual to offer. What was once Netent at the top of our list, these days, we also love games from numerous other providers like Big Time Gaming, Playtech, Elk Studios, Yggdrasil, Microgaming, Thunderkick, QuickSpin, IGT, Red Tiger Gaming - the list goes on. Suffice to say; you'll find the latest slot reviews from the best game providers.

Slots features & Bonus Features

The great thing about online slots, especially real money online slots, is the features they boast. As a priority, when reviewing a game, we look at the game's features. We'll get the game loaded and will start spinning the reels to see what it's all about and to test the in-game features that it's built with. We want to find out how fun and how engaging it is. It's a slot game that is boring for the first couple of minutes; likely, it won't change much thereafter. So, a slot really has to make a good first impression. We look at how many reels the game has, how many paylines, and some other 'basics' like the minimum and maximum bet. We understand that everyone has different budgets when playing slots, so we always list these features early on as a quick reference. We then check the paytable to see what symbols are the highest and lowest paying icons, as well as to read the rules and gameplay instructions to understand how to trigger bonus features and how to land winning combinations.

We then have a look at the slot's bonus features, which can really open up a whole new world of gameplay. From classic games to modern new slots, bonus features are becoming bolder and more fun as companies always invent new ways to entertain. One of the most beloved features among slot players is the 'free spins' feature, as well as other bonus games that Wilds, Multipliers and Scatters can trigger, so we always look out for these. We then also look for other unique features, that not all slots may have, such as random pop-up wins, pick-and-click features and avalanche reels. No two slot games are the same, but new slots often feature one or more of the bonus as mentioned above features, so we endeavour to list every single one so you know what's in store for you.

RTP% & Variance

Often overlooked by many casino customers is a slots default RTP% and Variance mechanics. To us, these are small, but highly important pieces of information to know about a game. A slot RTP % (short for "theoretical return to player") is important to understand as it determines how much a slot game will payout. For instance, if a slot has a 96% RTP, then the slot game will pay back 96% to players over time. As an example, for every £100 that goes into the slot, it will pay back, over time an average of £96. This, unfortunately, does not mean that if you wager £100 you are guaranteed to win back at least £96; it's a figure based over time and over millions of spins, which is what makes the game fun to play.

Furthermore, a slots variance mechanic is also important to understand too. High, medium or low variance describes how a slot game behaves. For example, a low variance slot is a game that will pay out wins frequently but usually with lower returns. On the flip side of that, a high variance slot will pay out less frequently, but when it does, the returns tend to be much larger. A medium variance slot is somewhere in between. We have a whole article about the highest rtp % slots here if you want to find out which UK slots pay out the most.

Our reviews list the variance of each slot as a focal point because it's important to know. Some slots aren't compatible for some players and choosing the wrong variance slots can be a major clanger. For example, if you opt to play a high variance slot but have a modest to small cash balance, the game will eat up your balance before you land any wins. Which of course, is absolutely no fun for the player. If they'd chosen a low variance slot, then the outcome may have been much better. Another example: if you are a high roller, meaning you enjoy riskier and bigger bets, then a low variance slot will not be entertaining for you, because the wins are small. You should play a slot depending on the style of player you are, and the balance you're playing with. 

Theme, Graphics & Audio

For us, a slot game has to be visually appealing and sound good to play. Whilst an online slot may have the best bonus features, a slot game needs to be visually appealing primarily. Of course, this also comes down to personal preference, but on the whole, a slot much have state-of-the-art high-definition graphics and a fitting soundtrack to boot. We also look at themes too. Many popular slots in the UK have themes based on Norse Mythology, Irish Luck, Arabian Adventures, Ancient Egypt, Sci-Fi and cartoons. With technology advancing all the time, graphics quality has improved dramatically over the last few years. Undoubtedly, today's slots can offer an immersive playing experience that provides much more than just a slot game. So there's no leeway for slots with terrible graphics; there are plenty of other slot games with terrific designs!

Mobile Compatability

It's estimated that over 60% of online slots players enjoy playing mobile slots on the go, so it's important to ensure that slots are fully mobile-compatible. Nowadays, virtually all new online slots are produced with HTML5 technology, allowing them to be accessible on all touchscreen mobile devices via mobile browsers. During our research, we always check how the game works on different mobile devices and operating systems, to ensure that nothing is lagging or missing from the desktop version.

Slot Review Analysis/Verdict

Once we've played the game at length and have exhausted our findings, we'll conclude the slot review with a summary to offer our last thoughts and who we think will enjoy the game. We understand that one person's favourite type of slot will not be the same as the next person's, so we try to review as many different slots as possible, never concentrating on the same type of slot too much so that everyone reading will find something interesting.

It's important to know everything about a new site before you get started, which is why our new slot site reviews will help you in the right direction. Our focus is to provide clear and accurate information on the following features:

? Slots Portfolio

We look at the variety of slot providers and also the games available. A slots site should have a broad range of titles to play from only reputable providers. Slot sites should offer popular games, new games, and the large paying progressive jackpots.

? Bonuses & Promotions

Top slot sites will offer plenty of promotions and bonuses, with a generous signup bonus for new players. We rank slot sites on their bonuses, from the first one to the amount they offer if you become a regular player, as well as promotions such as cash giveaways, slots tournaments, cash bonus incentives, gifts and their VIP and loyalty program.

? Payment Methods & Withdrawal Times

 We look at the major options for depositing and cashing out and how long it takes to withdraw. It's important that you aren't waiting a long time for your winnings and that you have access to plenty of ways to pay. We also look for other things worth considering, such as pending periods and any applicable withdrawal fees.

? Customer Support

 New slot sites must offer top-notch customer service available to members around the clock. We always check for a working email support address, 24/7 live chat facilities, and a comprehensive FAQ section. We also test the customer service to ensure that staff are quick to help and offer concise and expert knowledge.

?Reputation & UK Gambling Commission License

 All slot sites we recommend here at UK-OnlineSlots.co.uk are each licensed and regulated by the UK Gambling Commission. That’s not enough, though. We also look at their reputation, if they’ve had any issues in the past and how they conduct themselves regarding safe and responsible gaming and compliance.

New Slot Sites Bonuses in the UK

A popular way for new slot sites to stand out from the crowd in today's saturated market of top-quality online casinos is to offer big and bold welcome bonuses. There are many different types of online slots bonuses available so if you are looking for the best new slot bonuses, then look no further than our top lists of new slot sites. We've handpicked them on their merits of providing a safe and responsible casino service and offering fair and big bonuses, amongst many other things.

Claiming new slot bonuses is a great way to try new slot games and enjoy a well-rounded, fresh slot experience. Often welcome bonuses can double or even triple your deposit amount, giving you more time playing online and also allowing you to bet in different ways - for longer and fr some people, reach those higher bet amounts. Make sure you read our reviews, which cover bonuses and promotions in detail. Here's are the most popular new slot bonuses you can expect to enjoy at new slot sites in the United Kingdom:

New Slot Sites with a Free Sign-up Bonus

Many new slot sites offer a free sign-up bonus as a way to entice new players to join their casino and try games without any risk losing their own money first. To play with a free sign-up bonus, simply find a new site that offers a free welcome bonus (there are some listed above, though many new slot sites insist on a small deposit to trigger their welcome bonus these days). Then, all you have to do is register a new player account and enter the bonus code (if prompted). In some cases, the casino will automatically credit the free bonus to your account and then get started playing free slots! It's important to point out that in the last couple of years, new slot sites offering a free sign-up bonus or no deposit spins have become scarce due to the heavy marketing and operational restrictions and constraints placed on them by the UK Gambling Commission.

How To Choose a New Slot Site

We're confident that you will find the best new slot sites in the UK with our reviews. How to choose a new slot site is simple, and usually comes down to your own personal choices. As long as you choose to play at safe and responsible lot sites, then the rest is relatively easy. Take our reviews of new slot sites. Take a few moments to read them and compare the sites. Check out the bonuses on offer. Many of our new slot sites offer different bonuses when you sign up. Choose the slots bonus that suits you the most, or the bonus which will give you the most for the money you intend to deposit. Check out the games. Don't just assume that a casino will offer all the games you want to play; whilst many new slot sites offer 1,000's of slot games, not all offer the same collection of casino game providers, especially when progressive jackpots are concerned. Another helpful tip on finding the best new slot site is to get the feeling of it. Have a look and ask yourself "can I have fun here" "Do I like the look of this casino? "Is this slot site "me"? Once you have a few nailed down, why not try them out for size?

Responsible Gambling

We don't offer free-to-play slots or any real-play casino games directly on this website; we are solely an online slots and casino review website with one aim in mind: to make sure that you have all of the necessary information to help you get online to play slots safely and responsibly. If you're looking to play real money online slots or casino games, then make sure you do so at reputable casino sites that the UK Gambling Commission licenses. You will only find those sorts of sites here. We are also highly conscious that we write about online gambling which involves real money and that gambling for some can come with its own issues. Gambling can be addictive for some and we are stout supporters of responsible gambling.

Whilst we recommend gambling sites and review them at length, the last detail we check is how responsible the site is. We understand that some people can access gambling sites that have a serious gambling addiction that can affect them hugely, as well as many others around them. This is why we recommend sites that are members of the Gamstop scheme and offer tools to help control and curb problematic gambling. We also ensure that any minors and children who may access this site are not targeted in any way, such as reviews of slots with a childlike cartoon theme or those which offer free play games. If you are under 18, as per our terms and conditions, you must stop using this website immediately.

Suppose you need help and or advice in preventing your online gambling activities. In that case, you can always visit BeGambleAware, as well as Gamstop - which will block you from joining all participating gambling sites for a set period. For full details, please see below.

Online Slots- Frequently Asked Questions

We try to fill our pages with as much information and knowledge about online slots and casinos as we can (without waffling on or not getting to the point directly!). We hope you have managed to find all the information that you were seeking, however, to finish things off, we thought we'd add a list of FAQ's we commonly hear about online slots and playing slot online. You're not the only ones wondering them, which is why we're adding them below:

? Are All New Slot Sites UKGC Licensed?

Yes and no. The new slot sites we recommend on this site are each fully licensed by the UK Gambling Commission and are, therefore, heavily regulated so that you, as a punter, are fully protected. Like with any industry, there are, unfortunately, some unlicensed new slot sites that operate illegally in the UK. We urge you to steer clear of these as you are not protected as no one regulates them as they are not licensed. They operate offshore. We recommend that you always check the slot site's licence and certification or better still - go with some of our recommendations so that you are safe when you play slots online.

? Can Online Casinos Rig Their Slots?

No, they cannot rig their slots as online casinos have little impact on how their slots are programmed as they are integrated by a third party. There is nothing a casino can do to change the outcome of their slots. Only the vendor (such as Netent, Play N Go or Microgaming) can set the RTP % value and outcome of the slots. All slot sites which are UKGC licensed each offer fully regulated slots which are each independently checked and audited on their outcomes. It's only if you were to play at unlicensed gambling sites (not recommended) that you may fall prey to rigged slots.

? Are There Ways To Cheat Slots?

Unfortunately, there's no sure-fire, foolproof way to win at slots because they are a game of luck with entirely random outcomes, so there is just no way that you can "beat the slot" no matter what tips you hear; all slots are set to give out entirely random outcomes! Be wary of anyone telling you otherwise, they may be rigged slots or simply not telling the truth.

? Where Can I Play The Newest Slots Online?

Because the online casino world is competitive (there are so many new casinos saturating the market) the best slot sites will always launch new slots on a regular basis. With that said, to always have access to the latest slots, you should opt to play at new slot sites. Our new slot sites always have new slots released daily, from a multitude of premium and diverse casino game providers including Netent, Microgaming and Play 'N Go.

? How Can I Get Some Free Spins?

Most, if not all new UK slot sites often use free spins bonuses as a way to attract new players and also reward the loyalty of returning players. To get the latest free spins bonuses, you will understandably need to deposit a minimal amount (often between £10- £20) but depending on the casino, you can get up to 100+ free spins on new and popular slots.

? Can I Play Mobile Slots on My Phone?

Yes, you can easily play mobile slots across all devices. Many new slot sites provide a cracking mobile website and in some cases a fully functioning, easy to use mobile App. Both will give you instant access to hundreds of popular and new mobile slots. Most mobile casinos offer over 1,000 mobile slots and casino games with a fully supported customer service and easy to use banking options which are accessible via your mobile browser.
