UK Slot Sites

THE BEST SLOT SITES REVIEWED AND RATED

The editorial staff at TheSlotBuzz have experience as both players and operators in the online casino industry.

Our writers have worked in CRM, VIP and customer support teams at top tier online gambling operators in the UK. We have also spent time and money over the years playing slots at many of the numerous online casinos available to players in the UK.

This experience puts us in a great position to provide the right kind of information to help you decide where to play online slots and spend your money.

We know that the priorities for a seasoned slot player are fast withdrawals without the frustration and anxiety of a 48-hour pending period, slick and friendly customer services where the agents and VIP managers know their jobs, a game suite packed with titles from all your favourite providers, that little edge that favourable wagering requirements can give, and everything else that goes into making a great casino experience.

That is why our reviews are amongst the most informative and comprehensive you will find anywhere. We ask you to take the time to browse our listings and read more about each site before you pick where to play next.

HOW WE REVIEW EACH SITE IN OUR LISTINGS

There is a huge choice for online slot players right now. So many sites and games to choose from. It helps to be informed. That is why at The Slot Buzz we don’t just look at the headline welcome bonuses offered by each casino, we research and present all the key features, including the following:

  • Bonuses and Promotions – New Customer Offers, Existing Player Promotions and VIP club.
  • Bonus Terms and Conditions – What are the wagering requirements? is the bonus redeemable? What are the maximum bets and the maximum wins with a bonus? Are any payment methods excluded for deposit bonuses?
  • Games Catalogue – Which games supplier works with each slot site and which of their games are on offer?
  • Site Usability and Games on Mobile – Is the site easy to use and how does it look on mobile and tablet? Can you sign up and deposit with ease?
  • Cashier – Which payment options are available for deposit and withdrawal and are there any fees? How much can I deposit and withdraw at one time?
  • Account Verification – What is the process and how long does it take?
  • Progressive Jackpot Wins – What is the procedure to withdraw a jackpot win and how long does it take? Can I withdraw all my winnings in one go?
  • Customer Support – What is the reputation of the slot site for customer services and how accessible are the team through phone and live chat?
  • Security and Licensing – Under which jurisdiction is the site licensed? What kind of protection does this give the customer and what kind of scrutiny does this put its games and services under?
  • Awards and Accreditations – Does the site have any awards or has it been accredited by one of the industry’s watchdogs?

These questions form the basis for all our slot site reviews and the answers lead us to award a score out of five for Game Catalogue, Payment Options, Withdrawal Times, Customer Support, Licensing, and Overall Service.

With all this information available in one place, and with our ‘At a Glance’ information boxes, we hope you find our site reviews helpful, informative and easy to use.

Finding the Best Welcome Bonuses

Bonus Terms and Conditions
Bonus Terms and Conditions

The first feature of any slot site to grab your attention will most likely be the welcome bonus package. Making sense of it isn’t always that easy. Here is a quick guide to the most important things to look out for when weighing up each bonus

  1. How Is The Bonus Triggered?

Consider what the necessary actions are to trigger the bonus, and decide if you are comfortable meeting them. Almost every casino will gift a bonus of some sort on the first deposit made, but you should always check the minimum deposit required to trigger the bonus. Usually this will be £10 or more. Remember, depositing £5 twice will not qualify you. Also look for the maximum bonus amounts and remember that if you deposit in excess of the maximum amount, your bonus will be capped.

2. What Are The Wagering Requirements?

Always check out the wagering requirements on any bonus, or the winnings from any free spins. You will usually be required to turn over your bonus or winnings a specified number of times before a withdrawal can be made. And when hitting these wagering requirements be careful that you don’t exceed the maximum bet value – often £5 – or your wagering will not count towards the offer

3. What  Game Restrictions Apply to the Bonus?

Further restrictions to look out for include the games that are available to play with bonus money. Typically slot machine sites will restrict players to wagering bonus money on popular, low volatility slots like Starburst. The chances are you won’t be spending your bonus chasing those big wins on your favourite progressive jackpot game! That said, you should always shop around because some bonuses are more flexible than others

4. Is Your Payment Option Valid for the Bonus?

For those who like to deposit using eWallet payment methods, check the terms of the sign up offers to see if your preferred option will make you eligible for the bonus. Typically, Neteller and Skrill are not valid.

5. Does the Bonus Have an Expiry Time?

Finally, if you are not planning to wager all that bonus money on day 1 then we urge you to take heed of the expiry terms of your bonus. A bonus will usually be available to claim from the time of registration for seven days or more – though some slot sites may restrict this to just 48 hours – and the bonus itself will be valid for up to 30 days before it is forefeited. So, don’t forget those bonus funds – they are there to be spent.

Casino Bonuses, Advertising Standards and Transparency

Advertising Standards Authority
Advertising Standards Authority

The online gambling industry came under close scrutiny in 2017 following some high-profile cases that were also widely reported in the media in which advertisers were seen to be using questionable practices and socially irresponsible content to push gambling offers.

At TheSlotBuzz we aim to make the terms of all the offers listed on our site very clear and transparent and to follow all guidelines on compliance to the letter.

Advertising codes are written by the Committees of Advertising Practice (CAP) and applied by the Advertising Standards Agency (ASA). They include guidelines stating that gambling advertisements should not appeal to those under 18, promote gambling as a means to resolving financial problems, or suggest any link between gambling and sexual success.

Slot Game Software

Micorgaming Slot Software
Microgaming are one of the biggest software companies

For many of us of course, the most important feature of slots sites will be the games on offer. There are many different software companies out there, from industry giants like Playtech, Microgaming and NetEnt, to newer studios like Red Tiger Gaming and Thunderkick. Each will have their own graphical styles and game types, with varying volatility, RTPs and maths models.

Not every casino brand is in partnership with every software supplier so before you make a deposit you should look to see which slots you can play at each site. Some brands sign exclusive deals with one supplier – this is common in the case of Playtech and Microgaming. Others will partner-up with multiple suppliers to provide a wide range of games. For our money, the latter are the best sites to play at, offering the widest choice in their game catalogues.

You can see which suppliers are working with each slot site in our listings. For more information read our casino gaming software page and reviews of the major slot game suppliers.

Cashier Options at Slot Sites

There are many different ways to deposit and withdraw into your online casino account. Whilst the debit card options will always be the most popular, there are plenty of other methods to consider, each with its own merits. We recommend looking at eWallet solutions like Paypal which are very popular and allow customers to manage their gambling spend across multiple sites from one wallet safely and securely.

Check our casino payment methods pages for more information about this.

A Note About Licensing for UK Slot Sites

UK Gambling Commission
The UK Gambling Commission

All the slot sites listed and reviewed at The Slot Buzz are licensed by the UK Gambling Commission. Under the terms of these licenses, casino operators must offer a fair, safe and secure service to their customers, or they risk penalties, including fines, or in extreme cases, having their licenses revoked.

This means that you can feel safe that your data is well protected, your financial transactions are secure, and the gameplay at your casino is fair. It also means that should you have a complaint to raise against an online casino then you have recourse to do so. You can read more about this in our Fair Play gambling guide.

Most operators have businesses based outside the UK in other gambling jurisdictions like Malta, Alderney or Gibraltar, from which they will also have been issued with a separate license. At TheSlotBuzz we have listed information about each jurisdiction, including contact information and complaints procedures, on our licensing pages.

UK SLOT SITE FAQs

1. Which is the best online slot site?
The best slot sites have a wide variety of games on offer from all the leading slots developers. They give a generous welcome bonus package including free spins on the best slots, and high-value deposit matches with fair terms. The top casinos also support a good range of payment options, including eWallets and pay by mobile services. We rate all the slot sites in our list here. One of the best currently operating in the UK is Leo Vegas Casino.

2. Which slot site has the best odds?
Slots and casino games payout according to the metric of Return To Player (RTP) which shows how much money will be paid back in winnings from all the money wagered. This is a theoretical and average rather than an absolute value and it will change from session to session. It is similar to the odds of winning. A game with a 95% RTP will pay back £95 in every £100 wagered. Casinos sometimes publish the aggregated RTP of all their games each month. To find a casino with the best odds you should look for one which offers lots of games with a high RTP.

3. Which slot site has the biggest payouts?
The payouts of a casino are determined by the games they offer. The highest payouts come from slots that have a big win potential or offer big progressive jackpots. You can always find the payout potential of any game in the information screens that appear after it has loaded. This website reviews games with the biggest payouts, including Lil Devil by Big Time Gaming and Progressive Jackpots like Mega Moolah.

4. Can I win real money playing slots online?
Yes, it is possible to play slot games and win real money at licensed online casinos in the UK. In order to win real, withdrawable cash you will need to deposit using a debit card, or an eWallet service like Paypal. Most slots can be played from 10p up to £100 per spins (sometimes more) and offer payouts into the £1,000s. If you do win you can withdraw the money back onto the card or eWallet system you deposited with.

5. What is the best slot game?
There are thousands of online slots games to play at UK casinos. The very best ones have exciting themes and beautiful graphics mixed with thrilling gameplay and big potential payouts. Everyone has a different opinion on which is the best but the most popular include Starburst by NetEnt, Bonanza by Big Time Gaming, Play n Go by Book of Dead and Immortal Romance by Microgaming. Our site reviews and rates hundreds of games so you can make an informed choice on which to play.

6. Can I play video slots online for free?
It is possible to play slots online for free. However, since May 2019 it is necessary to first register and verify your age at a casino before you can spin the reels. This regulation was introduced by the UK Gambling Commission to prevent under 18s from experiencing slot play before they are legally old enough to gamble with real money. When you register at a gambling site you will be required to enter your name, address, email and date of birth. This will be enough to allow the operator to verify your age.

7. Where can I play a progressive jackpot slot?
Most online casinos will have a suite of progressive jackpot slots to play. Some have small prizes and drop their jackpots weekly or even daily. Others have multi-million GBP prizes that pay out infrequently but set records when they do. One of the best is Microgaming’s Mega Moolah. We recommend playing progressive slots at a Genesis Global casino called Casino Gods.

8. Which slot sites offer free spins with no wagering requirements?
It is now possible to claim free spins offers from casinos where the winnings are paid out in cash which can be withdrawn immediately. That means no wagering requirements. These free spins will usually be available on low variance slots like Starburst. Currently, you can claim up to 50 spins when you make your first deposit at Play OJO casino with no win limit and no wagering requirements (see site for terms).

9. Are online slots fair?
Yes, online slots are fair. All online casinos taking bets from UK-based gamblers must hold a license from the UK Gambling Commission. The developers who create the slots must also be licensed. Under the terms of these licenses, all the games must be audited and tested to ensure that they are fair, safe and secure. The use of Random Number Generator (RNG) technology ensures that the outcome of every spin is totally random and cannot be affected by activity outside the game engine.

10. Can I play slots on mobile?
More than half of all wagering on online slot games is now made on mobile phones. Game developers use HTML5 technology to ensure that their products are optimised for all devices. The games look best on full-screen phones and it is possible to sign up, deposit and play entirely from a hand-held device. There are also now payment services that allow players to deposit through their mobile without the need to use a bank account. Payments are added to the customer’s monthly phone bill or deducted from their pay as you go credit balance.
