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.

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.

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.

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.

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.

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.

The Importance of New Games for Players on Slot Sites

For online slot players, slot sites must frequently update their game selections with fresh and exciting titles. New games introduce innovative features, themes, and designs that improve the player experience and keep you engaged and returning for more. When selecting an online slot platform to play on, prioritizing sites that regularly release new games will ensure a constantly evolving and entertaining experience.

Popular Slots

Exclusive Games

Some slot sites offer exclusive games that cannot be found anywhere else. These games can be developed and hosted with providers and are used to differentiate their brand from their competitors. Exclusive games allow slot sites to showcase their creativity and innovation, enhancing their reputation and increasing player loyalty. Some successful examples of exclusive games include LeoVegas' "LeoVegas Megaways" and Casumo's "Casumo Bonanza." Slot sites offering exclusive games can provide players with unique opportunities while differentiating themselves in a highly competitive industry.

Participating in slot site tournaments can significantly increase the entertainment value for players. The thrill of competing against others to win exciting prizes adds a new level of excitement to every spin. However, it's important to acknowledge the potential risks involved in this kind of gambling. Responsible gambling means never chasing tournament prizes by wagering more than you can comfortably afford to lose. Set a budget, stick to it, and remember to take breaks.

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.

Payment Options

When it comes to payment options for slot sites, it's not always about having an extensive list of choices. While having a range of options is nice, it's more important to have essential payment methods available. These include debit cards and some eWallet solutions like PayPal. At OLBG, we recommend only the sites that offer secure and reliable payment options to ensure players can easily fund their accounts and withdraw their winnings.

Some of the possible online casino payment options that are generally available include:

• Debit cards, such as Visa and Mastercard
• eWallet solutions, such as PayPal, Neteller, and Skrill
• Bank transfers
• Prepaid cards, such as Paysafecard

Some slot sites may offer additional payment methods, but the options above are the most commonly used.

Credit Cards and Crypto Payments

Credit Card deposits are no permitted to UK Licenced slot sites and slot sites that accept cryptocurrency payments are typically licensed by Curacao and are not obliged to adhere to UKGC regulations. Therefore, users cannot rely on consumer rights or legal protection from the UKGC when dealing with these operators.

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.
