Unsafe UK slots casinos

Every now and again, we come across a casino that we recommend you avoid playing on. We have a strict 25-step review process, looking at things like a site’s software, promotions, how easy the banking process is, security and more. When any of these steps fall below our standards, the casino is added to our list of sites to avoid.

What our expert says

Badge verified
William Macmaster | Associate Gaming Specialist

"The UK casino market is thriving with all manner of new online slots popping up daily and countless slots sites for UK players to play them at. These casinos lead the pack regarding both the quality of bonuses and the quantity of games. Magic Red leads the pack in this respect. With over 1,000 games to play and a 100% match bonus of up to £100 and an extra 20 spins with no wagering attached, it stands out as a top choice to play at. This is just one of the great options available. We have the top 20 UK slot sites and beyond so you can find the right place to play. We also have everything there is to know about how to play online casino slots so that with our help, you will be spinning your way to success."

How we rate UK slots sites

Reputation and regulation

When rating UK slot sites, reputation and regulation are imperative to our review system. Ensuring they are a tried and trusted site with the appropriate licensing and security is the first step to recommending them to our players. In this regard, we are looking for licensing from the United Kingdom Gambling Commission and proof of regulation from eCOGRA.

Of course, equally as important to us is their security system and we expect SSL encryption software and some form of RNG guarantee from a third party such as iTech Labs. Moreover, we expect them to take care of you when it comes to responsible gambling. Therefore, looking for collaborations with BeGambleAware and GamCare further bolsters our opinion of them.

An added plus is any sort of prestigious awards that has seen them be recognised for excelling in an area of service at the likes of the Global Gaming Awards or EGR Operator Awards.

If we don't think a casino is trustworthy, then we will not recommend them to you.

Reputation and regulation

Game selection

Naturally, the slot game selection offered is a crucial element in our rating system for UK slot sites. Quality is as important as quality in our eyes, so we aim to make sure that they offer a wide range of slots that include the best slots to play online.

For a slot site to be considered one of the best then we are looking for over 1000 games on their books to give players the widest possible selection. These games should consist of all manner of slot types and include video slots, classic slots, progressive jackpots and a selection of Megaways slots too.

We would hope these include some of the biggest slot providers in the business and so include the likes of Netent, Playtech and Microgaming. The top slot providers not only bring the best slot games available on the market but their reputation amongst the industry, players and professionals, adds integrity to the slot site itself.

If the number of slots and the quality of slots is there, then they will receive top marks from us. Crucially, this means making sure that a wide variety of online slot gameplay types, including progressive jackpots, Megaways, and classic slots, are available!

Games

Bonuses and promotions

Looking for the best online casino sign-up bonus, free slot spins, or an online slots no deposit bonus? The UK slot sites we recommend to you will always offer you some type of bonus or promotion to give you an extra incentive to get those reels spinning. There are levels to promotions and we are looking for the best of the best.

For a slot site, free spins are what we look for first and foremost Of course, everyone loves no-deposit free spins that allow players to experiment with the service before a deposit so we like to look for these in our recommended casinos..

After a deposit though, anything over 50 free spins is a great start. However, in some cases, the quality of the free spins type is more interesting to us. The 20-wager-free extra spins at Magic Red, for example, are a great deal as you can keep what you win. With many deals, that is not the case and you will need to play with the winnings a set number of times before you can walk away with them.

When it comes to bonus cash amounts, 100% up to £100 is the standard, so we like to see that as a welcome bonus to get the ball rolling - with anything over that being a plus.

Aside from these deals, we like to look down the line to future promotional benefits too. Therefore, we take a look at any reload bonuses and loyalty schemes a casino offers that will keep slot fans busy with bonus gameplay and rewards for the weeks and months to come!

bonus

Tournaments

Aside from loyalty schemes, the more dedicated slot players may want to partake in-game tournaments that top-tier slot sites offer regularly. There are slot tournaments that happen across the casino landscape and others that are localised to one specific online casino.

For example, the Drop & Wins tournament available on Pragmatic Play slots can be played at a large number of online casinos. There are two versions of the Drop & Wins tournament you can take part in - weekly and daily.

If you are keen to get involved in either of these, you can head over via one of our links to Magic Red or Mr Mega and filter to their Drop & Wins section to get involved in all qualifying Drop and Wins games.

Alternatively, if you are looking for a local casino tournament, Pub Casino and All British Casino offer "Tournament" and "Extra Tournament Games" where you will games where players compete for different in-game accomplishments- for example, the Best Multiplier Wn.

These are great examples but all top slot sites should offer some form of slot tournament gameplay!

Payment methods

The top-rated slot sites recommended by us will offer a diverse range of payment methods to their users, including debit card options, Apple Pay, and a selection of e-wallets for seamless transactions that cater to a wide range of players.

Generally, we would hope for 5 or more options available for players to use, made up of a couple of debit and e-wallet options, plus another alternative, like a pre-paid card for example. However. the more the better to cater for a wide array of player's payment preferences.

We would then consider the on-site withdrawal process. Firstly, are withdrawals free of charge? This is a crucial factor to ensure players can keep what they win from the casino, without any unpleasant surprises. If they do charge, we will always aim to alert you of this so you know what to expect before you deposit and play.

The time it takes to complete a withdrawal process will also be considered. Generally, withdrawals can take between 3-5 days with some payment methods taking longer or shorter, but this is the average and hence what we expect. Shorter withdrawals will be rewarded in our ratings and vice versa.

Overall, we aim to ensure deposit and withdrawal processes are swift, efficient, and secure.

Payment methods

Mobile compatibility

The modern casino user wants to be able to access and play slot games on the go, so some form of mobile capability will be available at our top-rated sites. While a mobile site is a great start, a mobile app counterpart will help a slot casino score highly!

casino mobile icona

Customer support

If you ever have any queries or issues at one of our recommended slot sites, they can resolved quickly and easily as they will have an experienced customer support team on hand to help you out.

All will offer an email support system, with many others offering round-the-clock live chat or a telephone number to talk to someone directly. With the latter being the preference for a fast resolution to any issues.

Another determining factor for the quality of sites is the hours that support is available. Players can log in and play 24/7 at online casinos, so a round-the-clock customer support service to accommodate this is preferred.

How to play online slots

One of the biggest benefits of online slots is how easy they are to play with great gameplay easily accessible to even the most inexperienced casino players. Check out our step-by-step guide to get started.

  • 1
    Choose one of the top-rated slots site UK players can access from our list above and create an account.
  • 2

  • 3
    Read the game instructions to understand the paylines and bonus features of the game.
  • 4
    Choose your bet value and spin value. Higher bet values do mean higher potential wins, but it makes bigger losses more likely too! Play responsibly.
  • 5
    Spin away!

Slots mechanics & gameplay

There are two elements of online slot gameplay, the base game and bonus rounds!

🎰 Base game

The base game in a slot is where you will attempt to turn your spins into cash by lining up symbols on the slot reels in what is known as "paylines" or "win lines".

Different symbols will have different values with higher-value symbols offering you better payout amounts if you line them up. Paylines and symbols will vary from game to game with some offering more than others.

Most slots also have special symbols. The most common are "Wilds" and "Scatter Symbols".

  • "Wilds" can be found on most slot games and can form a payline in conjunction with other symbols on the reels to trigger payouts, as well as sometimes having cash values of their own.
  • "Scatter Symbols" can be found on many slot games too but often do not have value. Instead, their benefit comes from having the power to trigger a bonus round or game when 3 or more appear in view on selected reels.

🏆 Bonus rounds

Bonus rounds come in many formats but they all promise the opportunity to win more cash quicker.

Generally, they take the form of a "free spins" round where you will be awarded in-game spins that do not deduct from your cash balance.

During a free spins round, any number of other features can trigger in unison to boost your overall winnings during the round. At the end of the free spin round, you will be awarded the total amount won in the free spin round directly into your casino credit.

Some games offer a bonus round which essentially works as a mini-game secular from the normal reel gameplay. For example, you may have to open boxes to uncover cash amounts or roll a virtual dice to navigate an in-game board which will have an impact on the the base game reels.

However, not all slot games offer bonus rounds. Bonus rounds on classic games, for example, are rare. Most video slots, however, will offer either a bonus round or some of the other following features.

Other slot game features

The below features can appear either in the base game or the bonus round, depending on the game you are playing. While many games will offer at least one of these features, some may not offer any while others may offer several.

  • Cascading Reels - Symbols that disappear when aligned in a payline causing the reels to drop down - potentially triggering more wins as the reels realign to cause more symbols to align into new paylines.
  • Multipliers - An element of the game where winnings are multiplied gradually as your number of payouts in a row grows.
  • Respins - A free new spin that occurs after a paid or bonus spin due to an in-game event, giving you a second chance to win on that spin.
  • Expanding Wilds - Wilds that extend to cover whole reels when triggered to cause a higher likelihood of achieving a payline.
  • Exploding Wilds - Wilds that explode when triggered, cause a larger influx of new symbols to appear on reels close to the exploding wild.

Why play casino slots online?

The popularity of online slots is unquestionable but why should you play them? Well, there are a couple of key reasons that entice players!


Convenience

Slots have been a feature of real-world casinos for decades and have always been one of the most popular products. Therefore, when the first new slot sites launched in the late 90s that enabled players to play from the comfort of their own homes, playing slots online became an instant hit. Today, playing slots is a quick and easy process, where even if you are a beginner, you can start playing in a matter of minutes. This convenient process has elevated slots to be the most popular games available at online casinos!


Variety

Variety is one of the biggest differences between real-world and online slots. Slot game providers offer numerous themes ranging from everything from TV to Ancient Egypt slots. However, the biggest benefit in variety stems from the game types available at slot sites. With progressive jackpots, multi-reels, classic slots, and the ever-popular Megaways slots, there are countless ways to diversify your gameplay and enjoy a unique experience every time you log on to play!


Promotions

Promotions and slot bonus deals have given players an extra reason to log on and play online slots as they can get a little extra spin for their buck! With welcome offers and no-deposit bonuses to get you started, reload bonuses and free spin slot deals to keep you going, and loyalty schemes to reward you for being a consistent player, it is always possible to benefit from some extra gameplay when you play slots online.

Check out our new casinos page for all the latest information on the best new slot sites UK players have access to.


Best first-deposit welcome bonus slot sites

If you are joining a new slot site, make sure you opt-in and make the most of your new slot site's welcome bonus. This usually includes a package deal of a deposit bonus combined with a set number of free spins that you can use on a designated slot game. This allows you to try out your new casino and some of the top slots they offer users before making a deposit.


Best slot sites for free spins

If you are looking for free slot spins, choose one of our top casinos that offer this as part of a welcome bonus, as a no-deposit deal, or as a recurring feature on their promotions page. For those looking for extra benefits in the long run, you should also check to see if your new slot site offers a loyalty program where free spins can also be earned from regular gameplay.


Fast withdrawal slot sites

While your withdrawals can largely depend on the withdrawal method you have chosen, it can still be the case that your slot site's withdrawal times are slower than one of the other sites on the market. To best ensure you get your winnings as soon as possible, find one of the fast withdrawal slot sites available on the UK market and opt for a faster withdrawal method!


Best UK slot sites for Megaways

Games that use the Megaways mechanic nearly always feature in lists of the top 20 slots for UK players. The reason for this is simple: more paylines equal more opportunities to win and that is the aim of the game on online slots. If a casino offers Big Time Gaming as a provider, you will likely find a Megaways slot on their books. However, if you want the best online slot sites in the UK for Megaways then check out our reviews before you join them.


Best progressive jackpot slots sites UK

Another incredibly popular slot type for UK players is progressive jackpots. The difference in values of these progressive jackpots and the type of jackpot payout at UK slot sites can vary a great deal. There are several main types of progressive jackpots on the market, including Must Drop, Daily Drop, and Mega Drop Jackpot slots. The best slot sites in the UK for progressive jackpots will offer all 3 of these jackpot formats, as well as classic progressives to boot!


Best mobile slot sites

Gaming on the go is great and with the best mobile slot sites in the UK at your disposal it just got even better. Every one of the slot sites listed on our page will offer players the opportunity for some mobile gameplay via mobile. The best mobile slot sites will even offer a downloadable app where all the same great slots, bonuses, and features can be found!


Minimum deposit slot sites

Looking for a low-entry-cost UK site to play online slots for real money in the UK? In that case, minimum deposit slot sites are what you need. These offer a lower minimum deposit than other casinos which means for just a couple of quid you will be able to access the best online slots available online!

Slots strategy

Online slots are entirely reliant on chance, but that doesn’t mean there aren’t things you can do to put yourself in a better position to win. Experienced players follow a distinct strategy, like only playing games with the highest payout percentages, practising their bonus rounds and knowing their paylines inside and out. Follow these guides to give yourself the best possible chance to win.

What is a payout percentage?

As a slots player, the payout percentage tells you how much of your money bet will be paid out in winnings. This means you can work out how much you could win on average. For example, if a slot game payout percentage is 98.20%, the casino will on average payout £98.2 for every £100 wagered. This is also known as Return To Player (RTP). We outline the RTP for each casino we rate so you can find the payout percentage on a slot machine easily.

UK slots software providers

Online casinos offer an expansive range of video slot titles, many of which come from a handful of industry-leading software developers. When it comes to video slots, these guys know their stuff. Here are some of our favourites to look out for at online slots sites:

  • Realtime Gaming - Providing games since 1997, they provide a huge number of online slots that stick to their mantra to "take gaming seriously".

The bets you place on a slot are going to have an impact on the amount you can win.

The higher the bet, the higher your payouts from the slot. Maximum wins, for example, can only be won with maximum bets.

Of course, while these higher rewards can be tempting, you don't want to power through your bankroll too soon.

Find the right balance between budgeting to play responsibly and seeking those bigger wins when the time is right.

Online slot sites – advantages and disadvantages

Advantages

  • Huge range of games - Slots are the most widely developed games on the market meaning that even smaller-sized slot sites will still offer dozens of games
  • Easy gameplay - The gameplay on slots is generally very easy. While some games offer bonus rounds or features that add extra elements, they are easy to get started on.
  • Huge win potential - This is particularly true for progressive slots but even normal slots can offer massive max wins that can pay out huge amounts.
  • Low-cost entry-level - You can start betting on slots from sometimes as little as one pence meaning they are easily accessible for all bankrolls.
  • Always new games - New slot games pop up daily which means you can constantly try new and innovative gameplay on new slots.

Disadvantages

  • Strategy is limited - While there is some strategy involved in slots, compared to table games like blackjack or roulette, you are limited in how much you can control your results.
  • Low odds - While some slots have higher RTPs, slots generally have very low odds when compared to other casino games.
  • Lack of social interaction - Unlike live games where you can interact with the gameplay, slots are very much a solitary playing experience.

UK slots FAQs

How do online slots work?

The basic concept of spinning the reels to match up the symbols and win is the same with online slots as it is in land-based casinos. The key difference playing slots online is that the variation of games will be wider, and you'll find that most online slots offer more reels and paylines, so your chances of netting a winning combination increases.

Can I play slots for free?

Yes. Most online slots sites will offer players the option to play some free slot games. This means you won't have to deposit any money to get started, you can simply enjoy the game for fun. But, you won't win any either. Despite that, playing free online slots is a great way to get a feel for slot games before you advance to wagering with real money.

What should I look for in an online slot casino?

After security and legitimacy (there are unfortunately a lot of rogue online casinos out there) you want to look at the payout percentage of an online slot. This is the percentage of the wagers paid in that the casino pays out in winnings. This is especially important if you're planning on playing for real money. A higher payout percentage generally means more money back in your pocket.

What’s a progressive jackpot?

This is a jackpot that builds up over time and then pays out a big sum of money to a single player. Most online slots casinos offer progressive jackpot slots so it's worth keeping an eye on the jackpot total and how frequently the game pays out.

Can I win real money playing online slots?

Yes you can. While online casino slots are ultimately a game of chance, many players do frequently win decent sums, and some lucky ones even score life-changing payouts. If you're in it for the big bucks, progressive jackpot slots will probably suit you best.

Are online slot casinos trustworthy?

Absolutely. Provided you play at a recommended online slots casino, and avoid any sites from our list of those to avoid, your personal details and your money will stay perfectly safe online. We independently test and verify every online casino we recommend so selecting one from our list is a good place to start.

How do welcome bonuses work?

Welcome bonuses reward players when they make their first real money deposit. The exact terms and requirements vary from casino to casino and some offers that seem too good to be true probably will be. Before you commit your cash, we recommend checking the wagering requirements of the online slots casino you're planning to play at. These will explain how much of your money you're required to deposit upfront, and what you can expect to receive in return. The best bonuses will offer large payouts on minimal deposits.

Which casino slot has the best payouts?

Progressive slots games pay out the most money, with Mega Moolah being the record breaker at about £16,705,495. Our list of top-rated online slot casinos shows you the recommended games paying out real money. There are a huge variety of online casino slots paying out varying sums. These include classic three-reel slots, multi-payline slots, progressive jackpot slots, and video slots.

How do I pick a winning slot machine?

To try improving your chances of winning a jackpot, choose a progressive slot game with a fairly small jackpot. These games pay out most often. Another method is to pick simpler games. If a game is complex and exciting, software developers have spent more time and money to build it. This could mean frequent wins are less likely. Either way, the slot machine will still be fair and random.

Are online slots rigged?

No, all regulated online slot machines are completely fair. The results are random every time, meaning that nothing in the game is rigged. To ensure fair play, only choose slots from approved online casinos, such as those we list on this page. Playing at any of these will give you a fair chance of winning.

How to choose the best online slots site for my preferences?

You need to make sure you are playing slots with high Return to Player (RTP) percentages, advantageous bonuses, good overall ratings and a theme you appreciate. Check out our recommended slots to play in 2024 section to make the right choice for you.

What is the legal gambling age in the UK?

Are there specific features to look for in the best online slots?

Absolutely. There are several features you should check for including the number of paylines, the payouts on offer, and what kind of bonus game, if any, is offered. You may want to check if it is a certain type of online slot machine, for example, a progressive jackpot or Megaways game, and who the software team behind it is as this can have an impact on design and functionality. Check out slot reviews to get an insight into the different elements we look for.

Does the amount I deposit at a slots site influence the payout?

While the amount deposited to a slot site will not affect the payouts, the amount you bet when playing the game will. Bigger bets mean bigger potential to win big cash prizes. On each bet level, there will be adjusted max-wins for the slot game you are playing and on some games, this is sometimes displayed clearly to you as you switch through the levels. However, while the big prizes are great, make sure you hand your bankroll effectively to get the most out of your slot gaming.

Do people actually win money with online slots?

Of course. People are winning money on slot machines every single day - with some earning big prizes. Every slot that is properly regulated and on the books of a licensed casino will pay eventually via a random number generator algorithm.

Are there specific UK slot site regulations?

As per recent updates in regulation for the UK Gambling Commission (UKGC), there are several elements of slots that are banned at UK slot sites. For example, Quick Spin and Auto-Play features which allow for the game to play with little input from the end-user are banned on UK slots. Bonus and feature buys are also prohibited. Aside from these in-game regulations, players cannot use credit card payments to fund their UK slot site accounts.
