The RTP, which stands for 'Return to Player', is the theoretical payout percentage of every slot. The higher the RTP, the larger the potential winnings. The industry average is 96%, meaning most slots will return 96% of what you bet over time.
We reviewed and tested each slot RTP, focusing on slot games reaching the 96% mark. Some exceptional slots with a lower than standard RTP also made it to our list because of their amazing features and entertainment factor.
User Interface
Though we don't judge books by their covers, it's essential to glance at them before investing. We looked at the best online slots sites and their design: easy to navigate with an aesthetically pleasing interface.

New Slot Sites in the UK: FAQs
What Is a Good RTP for New UK Slots?
Most slots hold an average RTP of 96%. Anything higher than this percentage is excellent. Some online casino platforms may even have these displayed on their slots.
What Is the Best New UK Slot for New Players?
We recommend Red Wizard, 100x Ra, and Power of Thor Megaway due to the high RTP and interface. However, we do understand that a lot of personal preferences and players’ needs factor in choosing the best new slot. That’s why we presented you with this list so you can choose the slot that resonates with you.
Which New UK Slot Has the Best RTP?
Though many of these top slots stand above the 96% standard RTP, Big Juan at Genesis casino has the highest at 96.70%, followed by Power of Thor Megaways at 96.55% RTP.
Are Most New Slot Sites in the UK Mobile-Friendly?
Yes - many slot sites in the UK are mobile-friendly, but some players may experience lagging or glitches with specific new slot sites, which is why some slots are built better for desktops.
However, many slots excel for mobile play as they have adequately optimised their gambling site to be compatible with mobile devices.
What Is the Best Mobile Supported New UK Slot?
Some slots are simply better for mobile phone play than others. Groovin' Reels, Vegas Twilight, and Red Wizard are the best built-for-mobile slots on our list.
Which UK Slot Games Are Better, Old or New?
All slots offer something unique to the casino world, but some have more features than others. Older slots are likely to have lower-quality graphics and fewer additional play mechanics, while newer slots constantly involve unique concepts. However, like Gonzo's Quest, some slot classics have stood the test of time and remain popular.
It all depends on the player. New slots can offer state-of-the-art features along with progressive jackpots but may be busy and overwhelming. In contrast, older slots can lack perfected mobile play and features but are reputable, well-reviewed, and often a cult classic. Who knows - maybe your new slot will become a classic in the future.
