New Slot Sites UK in April 2025

Compare The Latest Slot Sites in 2025

How We Rate New Slot Sites UK

While reviewing new slots sites, there are several key criteria we take into consideration to ensure they provide an all-round experience for gamers. Our experts give great prominence to those websites that guarantee a range of games, but at the same time are prepared to offer their customers bonuses fairly, have secure payment systems, sound responsible gambling tools, along with professional customer support. So, here is our breakdown into the main components:

Choose New Slot Sites For Your Preferences

KingCasinoBonus experts can help you choose a top new slot sites UK that matches your needs with a simple checklist:

Are all the slot sites 2025 on this page brand new?

Many slot sites fail to gain traction after their first launch, whether because promotions are lacking. When these dormant sites get revamped with a new look and welcome offer, we may add them as “new”. Players likely haven’t tried these sites before, so they are just like brand new slots casinos for them.

New Slot Sites with a Free Sign Up Bonus UK

One of the best ways to get accustomed to the new UK slot sites is by trying their collections with no-deposit bonuses on sign-up. To make your search easier, our KingCasinoBonus.uk experts rounded up some of the best deals you will find in April of 2025.

If you’re looking for newly launched platforms, we recommend looking at the Cop Slots deposit-free promo codes and Hot Streak no-deposit promo deals. While being new on the market, they know how to best introduce British punters to their websites with compelling free sign-up bonuses.

However, if you want to explore some of the more established UK slot sites, we have a more complete list of choices:

• CasinoCasino offers you 10 deposit-free rounds on Eye of Atum at 40x wagering. This slot title isn’t one you will usually find promotions for, so this deal is quite rare.
• All British gives you 5 no-deposit spins on Book of Dead with a 35x rollover attached. This is quite the norm across the brand new slot sites UK with investment-free offers.
• Yako rewards your sign-up with 10 deposit-free rounds on Viking Runecraft, which is another title you won’t usually find playable without funding.

New Slots Sites with No Wagering Offers in 2025

Check for a no wagering bonus at your new slot site, but know that it may require a top-up and, sometimes, the wager of your deposit. Still, a deal like Betfred’s £10 deposit bonus in the UK with 200 no wagering spins only needs to be wagered once. Monopoly Casino has a similar bonus but with fewer spins.

Spot new independent slots sites

We rarely see genuinely new and independent slot sites with no affiliation to existing platforms or operators due to the difficulty of obtaining a new UK Gambling Commission license and launching their standalone slot sites brand. To ease your search, you can find the latest new independent slot sites picked by KingCasinoBonus experts.

Try Out New Online Slots on Mobile

Most new slots are made with mobile users in mind, and thus, gameplay is smoother, while access to the latest features is easy. Whether you’re playing on iOS or Android, you’ll find the mobile versions of these games more interactive, thanks to touchscreen controls and portability.

If you are looking for the best mobile slot playing experience, you should try sites like Pub Casino. With more than 1500 slots on offer, this site is fully adapted for mobile play. The application isn’t offered, but you’ll be able to play all the games and claim your bonus right from your phone or tablet thanks to their friendly mobile interface.

Software providers release new slot games monthly, so KingCasinoBonus experts selected the top new slots for UK players based on our data on bonus game special features.

If you play at a new online real money slots site, you will likely find our favourite new slots released lately that you can play with a free slots bonus and grab daily free spins:

Best Payout Rates in Brand New Slot Sites

Getting the highest payouts in new slot sites depends on how much your favourite slot pays out over time. While helpful, Return-to-Player rates require significant play to balance out variance, which is unrealistic if you’re playing with 100 quid.

Best Payout New Slot Games in 2025

King’s experts have settled on the highest-RTP new slot games you can play this year:

High RTPs alone don’t guarantee profits, which is a common mistake new players fall for.

When selecting new casino sites to play the newest online slots, you should always check that they provide transparent and up-to-date payout info, say from eCogra.

The RTP percentages you see when publishing on casino or provider sites are considered accurate. But remember that RTPs are not stagnant and can fluctuate – especially in your experience as a player.

New Slots Providers to Explore in 2025

Established casinos rely heavily on legacy providers, while new slot sites in the UK are more eager to incorporate the latest gaming trends:

1. Red Tiger Gaming – RTG is one very innovative studio founded in 2014. Their rise to the top is based on features like adjustable paylines, smart bonuses and daily jackpots. Top Red Tiger titles include their new 2022 release, Gonzita’s Quest.
2. Quickspin – Sweden’s Quickspin launched in 2011 and focuses on video slots with vivid graphics and soundtracks. Popular Quickspin online slots include Pied Piper, Spinions and their Big Bass Bonanza series. Their slot games stand out with features like dissolving pays and re-spins.
3. ReelPlay – 2017 startup ReelPlay takes a storytelling approach to slots with rich themes, characters and narratives. Must-try new ReelPlay slot releases include Dawn of Egypt 2, Swirly Spin and their superhero-themed Electric Avenue series with 1024 bet ways.
4. Eyecon – Eyecon is a prominent figure at UK slot sites, best known for Fluffy Favourites. Eyecon casinos continues to charm players with its diverse range of slots, including Shaman’s Dream and Temple of Iris, found in popular casinos like SlotsMagic and PlayOJO.

Which providers launch the most new slots?

While new suppliers launch new slot games often, the established software vendors release the most new slots, namely Microgaming (Games Global), Play’n Go, NetEnt and Playtech. Barcrest is another true pioneer in the UK slot sites, known for their classic Rainbow Riches series.

Top Payment Methods to Use on New Slot Sites

You can most likely use PayPal, Visa and Mastercard – these are among the most popular methods that nearly every new online slot site accepts in 2025.

KingCasinoBonus experts recommend finding a top PayPal casino like the VIC to play new slots and enjoy fast withdrawal times. PayPal allows you to withdraw winnings in as little as 15 minutes, which is ideal to prevent wagering more than you intended.

Alternatively, new slot casinos may let you deposit with a wider range of e-wallets, such as Skrill, NetEller MuchBetter or EcoPayz. Some even include pay-by-phone deposit options like Boku, which we recommend especially for low rollers looking to deposit small amounts between £5 and £30.

Licensing & Safety Features of New UK Slots Casinos

A responsible UK player always asks themselves if their new slot site has a valid UK licence.

Are the newest slot brands safe and trustworthy?

Rest assured, our recommended new casino slot sites all hold a valid UKGC license. As experts, we thoroughly vet and review each new site before listing it here. Our priority is player safety and security.

Therefore, This automatically means that you can play the latest games, knowing that player safety is not an issue of concern.

New slot sites we recommend boast a number of responsible tools, which are designed to help you control your gaming activities. These include:

• Deposit Limits: Apply daily, weekly, or monthly limits to the amount you can deposit. This will not only control your bankroll better but also prevent you from overspending.
