Something new is happening in the world of slot sites every day. The team uses and reviews new slot sites daily, selecting only the very best for a full review and inclusion in the listings here at OLBG.

New Slot Site Selection

Chris Taylor, Jenny Mason, and I meet twice a week, on Mondays and Fridays, to discuss the agenda and decide which sites will be added. Sometimes, there may be a few, some weeks, none at all, but all the news will be right here every Monday, so you know what's new and what's coming up.

This Week's New Slots Sites News -

New Slot Sites Reviews in 2024

Over 100 new slot sites are listed on OLBG, selected from hundreds of options. Our Commercial Manager, Sam Darkens, consults our expert team to review and list only those that meet our stringent criteria.

The UK sees a range of new slot sites each year, from major players to niche operations. Some leave a lasting impact, while others fade quickly. Our team reviews these new slot sites, ensuring only those meeting our high standards are featured. Occasionally, you might find a site that appears new but has quietly operated for some time before being passed by our expert slot reviewers.

Best Slots Sites by Category December 2024

Not every slot site offers the same variety of games, and you may be looking for specific games to play. Renowned King of Slots, Chris Taylor Has picked the best of the bunch depending on what type of slot you are looking for.

Chris Taylor

My Picks This Month

Over the last 20 years, I've reviewed over 200 slot sites and played something like 10,000 slot games, and I consider myself the ultimate slot geek. This is my take on which slot sites players should use based on the style of game they like to play.

- Chris Taylor, The king of slots

Best Slot Sites for RTP and High Payout Slots

It may not be well known, but MrQ Casino offers the best RTP overall regarding its range of slots. I highly recommend them as a starting point if you want games set at the best payout levels. Games include Book of Dead at a market-leading 96.21%, Starburst at 96.09% and Big Bass Bonanza at 96.71%

Add fast withdrawals, a good welcome offer with no wagering restrictions, mobile-first technology, and a huge selection of games from the top providers. MrQ is your go-to for high RTP slot sites.

4.4 / 5 8 Ratings

MrQ Review

  • No. of slots 1000+
  • Payout speed Instant - 24 Hours
  • Win rate 95.6%

Best for High RTP Games

Fast Withdrawals, Free Spins, Big Wins and no Wagering Requirement, MrQ has a whole host of slots, live dealers and more on offer. With High RTP slot settings too!

  • Best RTP's in the business
  • Fast Withdrawals
  • No Wagering Welcome Offer

Best Slot Site for the Most Slot Games

We decided that the best slot sites would naturally be those with the largest number of slot providers, the widest range of games, and the most frequent additions of new slot games. I have gone for VideoSlot here, but consider MrVegas, which is the same platform. Outside of that, Party Casino and Casumo offer a large variety, too.

Video Slots

  • Over 5800 titles to choose from
  • The greatest number of slot games of any site reviewed by our expert team
  • Classic slots, progressive jackpots, and the latest releases from top providers
  • Excellent customer support
  • Don't miss out on all the features and benefits - check out our full review of VideoSlots!
  • No. of slots 5879
  • Payout speed Instant - 24 Hours
  • Win rate 95.7%

VideoSlots has always been popular on OLBG thanks to the vast slot range and trouble-free sign-up process.

  • Over 5800 Slots
  • Progressive Jackpots
  • V. Quick Sign Up

Best Slot Site for Progressive Jackpots

We can all dream of landing one of the multi-million pound progressive jackpots on slots. As I am sure you know, the chances are very slim. However, someone somewhere in the world will land one eventually, and they are attached to some of the greatest slot games available. The Kindred Group, which includes slot sites like Unibet and 32red, offer the widest range of progressive jackpot slot games to choose from and should be the go-to if you are looking for a choice in this category.

4.6 / 5 10 Ratings

Unibet Review

  • No. of slots 3750+
  • Payout speed Instant Options
  • Win rate Variable

Unibet Casino offers an unparalleled selection of online slots and jackpot games. From classic fruit machines, to new games and exclusive slots, Unibet has something for everyone.

  • Most Progressive Jackpots
  • Low Minimum Deposits
  • Exclusive Slots

Best Slot Site for Megaways Slot Games

There are always innovations in slot game mechanics, but by far, the biggest and most widely used still today is Megaways Slots; the games with 117,649 ways to win on a single spin.

If you've played one or two, like them, and want to find the most on a single site, take a look at Mr Vegas. They have over 200 megaways titles among 5,000 slot games, all easy to find from the main slots menu.

4.0 / 5 8 Ratings

Mr Vegas Review

  • No. of slots 5416
  • Payout speed Instant - 24 Hours
  • Win rate Variable

Mr Vegas's portfolio of handpicked games, including live casino, slots, video slots, video poker and classic table games like Roulette, Blackjack and Baccarat, as well as fast withdrawals

  • Over 200 Megaways Titles
  • Over 5000 Slots
  • Fast Withdrawals

Best Slot Site for Fast Payouts

Who wants to wait for a nice win to be paid back into their account or electronic wallet? Not me! For that reason, Duelz is a go-to for fast payouts from a slot site. Instant transfers are often achievable, but over testing, I have found that, on average, 6 minutes will see your funds back in your possession. Alternative options to Duelz are Casushi and the excellent Buzz Casino

4.7 / 5 14 Ratings

Duelz Review

  • No. of slots 1000+
  • Payout speed Instant Options
  • Win rate 96.5%

Duelz Casino is a medieval-themed online casino with over 2,000 casino and slot games. With weekly cashback and regular promotions, there’s an abundance of payment methods to use including 6 minute instant withdrawals.

  • Mobile-first Casino With Instant Withdrawals
  • Huge Range of Slots From Top Providers

Best Slot Site for Tournaments

Slot tournaments aren't really my thing, but I always take a close look when reviewing casinos, as many players like to opt in for prizes and competitions running concurrently with their regular slot play. Tournament opt-ins allow you to compete for prizes in play-tables and for instant wins, free spins and more. Netbet casino offers more options for slot tournaments than any other online slot site I have found.

  • No. of slots 4000+
  • Payout speed 24 Hours
  • Win rate 96.54%

NetBet Casino is the best place to find every kind of online casino game from slots and jackpots to card and table games. Find an old favourite or make new discoveries every day

  • More Slot Tournaments
  • Players Club Membership
  • Huge Game Library

Best Slot Site for No Wagering and Free Spins

One of the bug bears with offers, free spins and more from Slot sites is having a play through requirement, dictating that bonus funds have to be played over and over before becoming withdrawalble as cash - This can be avoided with some casinos that have free spins no wagering offers, and Kwiff leads the pack with not only a no wagering welcome offer, but also many promotions in the same ilk.

  • No. of slots 1400
  • Payout speed 24 Hours
  • Win rate 96%

The Kwiff casino sits snugly alongside the sports betting site and offers the full range of casino games including Live Casino games and dealers.

  • Free Spins Bonuses for Regular Players
  • Low Deposit and Withdrawal Limits
  • Great Mobile Performance

How We Rate and Select the Best Slot Sites

This is a breakdown of our slot site review and rating policy.

STEP 1 - Full Review By An Experienced Online Slots Player 

One of our experienced in-house slots writers will spend a minimum of two weeks reviewing a new slot site, playing numerous games and testing various areas of the site. 

All of our slots reviewers have been regular slot players for numerous years and consider themselves 'slot geeks'! They have played at hundreds of different sites and played thousands of slot games. 

These are some of the factors which our in-house team led by Chris Taylor reviews for each slot site we list at OLBG

  • Customer Support
  • Banking & Payment Options
  • Site Usability
  • Mobile site & mobile app usability
  • Wide variety of slot games
  • Variation of games, eg. themes, mechanics, slot providers
  • Promotions & Offers for existing customers
  • Welcome bonus or free bet terms
  • Overall online gambling experience
  • Ease of registration & Account Verification
  • Slot Tournaments
  • Maximum payouts


STEP 2 - Our Review Panel Rates Each Slot Site

During the third and fourth weeks of the process, the members of our review panel will test the site and provide their ratings. These ratings, along with those from our senior reviewer and slots content manager, form the base rating for the new slot site.

The panel will also review what was written by the initial writer and their feedback is built into the content to improve it. This part of the review process is significant because each member of the panel will be looking for different things from their slot site provider and will enjoy playing different table games or slots. Taking all of their feedback into account helps us to create a very thorough review. 

Then, it is on to fact-checking and detailed editing to ensure accuracy. 


STEP 3 - OLBG Members & Regular Slot Site Players Carry Out Their Reviews

We now have a written review and a base rating from the panel. Next, we will open the review process to OLBG members. Registered members can give feedback and provide their ratings.

Our users are asked to rate each slot site out of five and provide some written feedback about what they like and dislike. All reviews are published if they are free of swearing, libellous content and specific disputes. 

For specific disputes with licensed online slot sites, we suggest the customer contact the online slot site directly. If that doesn't reach a satisfactory conclusion, then  IBAS can help. IBAS is the independent betting adjudication service to go to when users don't feel that their complaint has been resolved by talking directly with a licensed gambling company in the United Kingdom. 

STEP 4 - Regular Updates and Improvements

Each of the reviews on OLBG is updated monthly at a minimum. Each month we read every new member review as this helps us to understand if a site has improved or changed. We can use this feedback to update the core review content. 

We will also ask a contact working for the online slot site operator if there are any significant changes or improvements since the last update.  

When there are big changes, like a site redesign, a full new review process is triggered. We go back to step 1 and start again! 

You can be confident that this rigorous process is carried out with all our slot site reviews. 

STEP 5 - Detailed Comparison 

Reviewing each slot site is the minimum. We then need to compare and contrast them in many different ways to discover which is best for you based on how you like to use an online slot site. 

We do this by building numerous slot site comparison guides. When doing this, our review team work together to discuss which operators come out on top and which ones don't make the grade. 

This ads up to 100s of hours of work by dozens of experts, all to help you to find your next slot site site. 

Who Created, Edited & Fact Checked Our Slots Content

Our slots category is the most recent addition to OLBG. As an avid slot fan, Editor-in-Chief Steve Madgwick felt that slot content required a separate dedicated area from casino content and so began strategising how this could be achieved. He wanted to create helpful guides and slot reviews and find the best offers for slot site players. The team was assembled.

The Experts Behind OLBG Slots Content:

Our team's commitment and specialized knowledge guarantee that OLBG will remain a reliable hub for information on slot sites. Every member's diligent efforts enhance the overall excellence and trustworthiness that our users value and enjoy. Discover our Slot Sites section and gain valuable insights from industry leaders.

Participating in slot site tournaments can significantly increase the entertainment value for players.

However, it's important to acknowledge the potential risks involved in this kind of gambling.

Welcome Bonuses

While sign-up bonuses, including deposit matches and free spins, may be enticing, they shouldn't be the deciding factor when choosing a top slot site. The real cash benefit may be minimal. We prioritize user experience and interface options when recommending slot sites. While sign-up bonuses may be a nice perk, they shouldn't be a weighted factor when evaluating slots sites.

User Interface and Experience

A good user interface and play experience are important when choosing a slot site; our expert team considers this a high priority. 

We exclude slot sites with clunky designs, interrupted gameplay, or those not optimized for mobile use from our recommended list. 

A good slot site must provide easy navigation, a sharp visual display, and smooth screen transitions to create an enjoyable and frustration-free user experience. 

The best slot sites prioritise usability and functionality to ensure our you can focus on playing and managing your account in the most simple fashion..

Sign Up Process

When choosing a slot site to join, one crucial factor to consider is the ease of registration. 

All sites require standard personal information such as name, address, and mobile number to verify your identity on a soft search. Usually, you'll need to set up a unique username and password for security purposes. At some point, sometimes before you can deposit and play,  you'll be required to upload identity verification documents [Driving License, Passport Bank statement, and complete affordability checks to meet regulatory obligations. 

Although some slot sites don't insist on document uploads at the start, they require them after a certain amount of time or money spent, so it's best to be prepared for this step. We have no preference for slot sites based on their document upload timeframe, as it is an inevitable step for continued use.

Withdrawal Times

Withdrawal times used to be a major consideration when choosing slot sites, but most now offer quick processing times of less than 24 hours, including for traditional banking accounts. While bank account withdrawals can still be processed and approved instantly within 24 hours, the time it takes for the cash to appear in your account depends on the bank you use. However, many transactions are now taking place as quickly as e-wallet solutions, which sometimes can be instant.

We have recommended only Slot Sites with a complete withdrawal process and approval (Subject to withdrawal amount) within 24 hours.

Safety and Security

At OLBG, we ensure that only UK Gambling Commission-approved and licensed slot sites are included in our recommendations. This guarantees the safety and security of customers' personal and financial details are managed correctly. Each slot site should have specific details publishedpslo on how customer funds are held and what would happen in the event of liquidation. Moreover, UKGC grades slot sites for the protection they offer customers, providing transparency of safety assurance.


Slot Sites Deposit Methods

One consideration you might have is which deposit and banking methods are best with Slot sites. Most slot sites offer debit cards, and you'll struggle to find one that doesn't provide MasterCard or Visa through Nuvei.

You will also find a wide range of eWallet and pay-by-phone solutions.

MasterCard, VISA or Pre Paid Cards

The most common deposit method for slot sites is a debit card, a straight transfer from a UK bank account. Online fruit machine sites can no longer accept credit cards as a deposit method. So you'll find Mastercard and Visa Electron the most popular, and Maestro is still hanging on there for the old-school players.

Prepaid cards can also be used. But beware: If using PaySafeCard, you will need another function added, as withdrawals cannot be administered in this format.

Electronic Wallets (PayPal, ApplePay, GooglePay, Skrill etc)

The market has many modern options, from ApplePay for Apple users to the convenient Android solution Googlepay. Paypal remains arguably the most commonly used for mobile slot sites, while Skrill and Neteller are very similar and have handy mobile apps to assist with transactions. 

Whichever method you choose, you can do so with confidence, thanks to the safety and security in place at UKGC-licensed and regulated online casinos.

A good rule of thumb is that if you do not recognise a payment method and you are looking at an unlicensed slot site (no need; there are hundreds of legit ones), you shouldn't use it.

Pay By Phone (Boku - PayForIt)

Yes, depositing into a slots account with your phone credit is possible using payment methods such as Boku or PayForit. Several slot sites qualify, although, in all honesty, it's not a highly recommended method. For one thing, imagine having a good win. If possible, you will not want to add a significant sum back to your phone credit when making a withdrawal.

👍 Responsible Gambling, Identification & Affordability Checks

In recent years, the regulations for online slot sites have tightened as the Gambling Commission has looked to increase the protection of the user. This is fantastic news for the industry and all who play sots online, but you need to be aware that you may have some minor inconveniences when trying to open a new account or if you want to place large bets. ID verification is very strict, and sometimes you may be asked to send off copies of documents for ID and address verification. 

Also, if you place large stakes or make large deposits, slots operators are responsible for ensuring you can afford to do so. You may be asked for affordability checks, such as showing your pay slips, or you may be asked for proof of funds for money laundering checks. Don't take such requests personally; all licensed online casinos must follow these regulations, or they can face huge fines.

Here are some common tips for gambling responsibly online. For more information, take a look at our detailed responsible gambling guide. 

✋ When The Fun Stops Stop 🛑

You will have seen 'When the fun stops, stop' used by slot sites frequently over recent years. It is trying to get across the serious point that if you aren't enjoying gambling, you should stop immediately. You can use a process of self-evaluation to help you to understand if you have a gambling problem. There is a great tool at Gamcare. 

If you believe you have a problem, there is always someone to talk to at begambleaware. They can offer great advice, including helping you to self-exclude. A valuable service called Gamstop allows you to exclude all gambling companies signed up to the program for a period of your choice. All UK-licensed slot sites on OLBG will be part of the GamStop programme. For this reason (and many others), you should never join slot sites not on GamStop.

 🔚Set Limits and Use Responsible Gambling Tools

We strongly recommend that you record your gambling activity and set your limits. Only stake what you can afford to lose. Online slot sites have started to offer several tools to help you with this. 

  • Deposit Limits 
  • Session Limits
  • Account History 
  • Time Outs


Using playing time notifications to remind you how long you have been gambling and when to stop is a useful tool and so is setting a specific loss amount you are happy with in advance.

  • What should I look for in a reputable slot site?

    When looking for a reputable slot site, consider factors such as licensing, customer support, game selection, and user reviews. A reputable site will be licensed by a recognized authority for the UK market including bodies such as the UK Gambling Commission and/or The Malta Gaming Authority.



  • Are there any specific features or bonuses that I should consider when choosing a slot site?

    Some features and bonuses to consider when choosing a slot site include welcome bonuses, free spins, loyalty programs, and regular promotions. Bonuses should not be viewed as an important consideration, over things like safety, security, user interface and experience along with the range of slots on offer from good providers.



  • How can I ensure that a slot site is safe and secure?

    To ensure a slot site is safe and secure, look for sites that use SSL encryption to protect your personal and financial information. Additionally, reputable sites will have a privacy policy and terms and conditions that are easy to understand along with regulatory licence information and link to the authority issuing the licence to operate.



  • What payment methods are typically accepted by slot sites?

    Most slot sites accept various payment methods, including credit and debit cards, e-wallets, and bank transfers along with pre-paid cards like PaySafeCard. Look for sites that offer various payment options to suit your needs.



  • Are there any restrictions on who can play at slot sites?

    Slot sites do not accept players under the legal age (18), and players from restricted geographical locations, such as countries outside of their licensing spread. Also, players who have self excluded from an operator should not be able to register a new account or reactivate previous accounts.

  • How can I compare different slot sites to find the best one for me?

    To compare different slot sites, consider factors such as game selection, bonuses and promotions, payment options, and user reviews. You can also use comparison sites like OLBG or read reviews from trusted sources to help you make an informed decision.

  • Are there any red flags to watch out for when choosing a slot site?

    Red flags to watch out for when choosing a slot site include sites that are not licensed or have a poor reputation among players. Additionally, be wary of sites that offer unrealistic bonuses or have unclear terms and conditions.

  • Can I trust online reviews and ratings of slot sites?

    Online reviews and ratings can be helpful in choosing a slot site, but it's important to read reviews from multiple sources and consider both positive and negative feedback.

  • What should I do if I encounter any issues or problems while playing at a slot site?

     If you encounter any issues or problems while playing at a slot site, contact customer support for assistance. Reputable sites will have a responsive and helpful support team that can help you resolve any issues.
