Brand New Slot Sites (November 2023)

Our Favourite New UK Slot Sites 2023 – Reviewed

Experienced slots player and KingCasinoBonus CEO Ionut Catalin Marin was key in evaluating our new slots sites UK list for 2023. Based on his observations, brand-new slot sites like MadSlots or Betgrouse usually have 10+ slot providers you didn’t even hear of! He is the one who will provide the list of pros and cons at the end of our review article.

Luck.com Casino – Overall Best New Slot Site in the UK

KingCasinoBonus CEO Ionut Catalin Marin chose Luck.com as the best new slot site in 2023; It got the first spot not only because it was established in 2023 but for its premium slot offerings.

Why Luck.com?

Luck.com casino only has 50 slots from renowned developers Slot Factory and Skywind, which may be seen as a drawback, but is regularly adding new games to the collection. This curated approach focuses on megaways, classic and video slots that deliver great quality gameplay

The library may seem small, but we think it is quite powerful, capturing the very best of both providers. Their slots selection manages to stand out because of hits like Big Buffalo, Jaguar Gold, and Sky Piggies, all having very distinct and exciting features.

King’s expert verdict 

While the selection is compact, Luck.com ensures a stellar slots experience:

• Low £5 deposits cater to casual players alongside fast payouts.
• The intuitive site also makes playing mobile slots user-friendly for newcomers and veterans alike.

Matchup Casino – Top Alternative New Online Slots Site

If you seek a larger and more mainstream slot selection in your brand new slot site, KingCasinoBonus.uk experts recommend Matchup Casino as the top alternative.

Why Matchup Casino?

The platform hosts over 2200 slot titles from major developers like Pragmatic, Blueprint, Microgaming, and Eyecon.

Here you’ll find fan-favourite UK slots, including titles such as Sweet Bonanza, Starburst, and Fluffy Favourites. The massive variety covers all themes and features – from cascading wins in Candy Rush to the Megaways mechanic in Legacy of Oz.

King’s expert verdict 

While not as niche and perfectly curated as our top choice, Matchup lets you enjoy tried and tested top hits you are already familiar with:

• Their range of 900+ slots appeals to all play styles.
• You get to play both low volatility and high variance slots.
• Matchup accepts low £5 deposits catering to small bankrolls, although you should be prepared for slightly longer withdrawal times.

MadSlots Casino – Best New Slots Site for No Deposit Bonuses

Our expert analysis brings you Madslots, the best new slot site for no deposit bonuses, given their 100 free spins on sign-up.

Why MadSlots?

MadSlots is a 2023-established casino from Viral Entertainment which has actually gone viral for its no deposit bonuses. We picked it for the generous offer for new players, but in our experience you’ll also get daily and weekly treats as you play on the platform. .

King’s expert verdict 

While Madslots’ no deposit spins are limited to Big Bass Splash, you can try various new slots when clearing the wagering requirements. More things to keep in mind:

• With over 1000 slots from leading studios, the free spins give you a way to sample MadSlots’ lineup.
• You can explore popular slots in the UK, such as Book of Dead, Legacy of Dead, and Bonanza with the bonus funds.
• Before signing up, be aware that MadSlots lacks progressive jackpot slots. If you like pooled jackpots, you should look at other new slot sites.

Betgrouse Casino – Best New Progressive Slots on Mobile

Betgrouse Casino stands out as the best new mobile slot site for progressive jackpot slots, based on the King’s expert research on iOS and Android.

Why Betgrouse?

Betgrouse Casino is the leading new slot site for progressive jackpots, and by a distance, thanks to a variety of titles like Mega Moolah, WowPot, and the newer Jackpot King releases. Their huge selection of networked progressives from top developers Microgaming and NetEnt have jackpots that exceed the £1000000 mark.

King’s expert verdict 

You can enjoy all the newest progressive jackpot slots in the portfolio via your mobile browser thanks to Betgrouse’s fast-responding and mobile-optimized site.

• Smooth access on both iOS and Android makes playing new progressive jackpots convenient on the go.
• If you play on smaller wagers, keep in mind that low-stakes penny slots are not available here.

Casushi Casino – Best New Slot Site for Megaways

After carefully reviewing the game collection, KingCasinoBonus.uk experts designated Casushi as the top new site for Megaways slots.

Why Casushi?

Casushi hosts various Megaways versions of famous slot titles, including Gonzo’s Quest Megaways, 9 Pots of Gold Megaways, and Wild Wild Riches Megaways.

On top of that, you will be able to find titles such as Aztec Wilds Megaways and Sweet Candy Cash Megaways, which were released in the past year.

King’s expert verdict 

We were glad to find Casushi’s roster of reputable slot developers, such as Pragmatic Play, Microgaming, and NetEnt, which bring novelty games periodically. Some things to consider:

• Due to licensing concerns, Microgaming’s newest slot games appear under the Games Global icon.
• Certain Megaways slots may be excluded from bonus play.
• Before you sign up for Casushi, be mindful that payout processing takes longer and live chat support is not 24/7

How to Pick New Online Slots Sites

KingCasinoBonus experts can help you choose a top new slot site with a simple checklist:

1. Check the New Slots sections – In these sections, you will find the latest titles added by a casino. Check the sections regularly, to experiment more with new and innovative features.
2. Use a slots no-deposit bonus – If you want to try out a new slot at a casino, you can use free spins or other slots no deposit bonuses to try before you buy. The no deposit and free spins bonuses mostly cater to new players at an online casino. However, there are plenty of ways in which you can maximize existing player bonuses to try out slots with additional funds.
3. Read expert reviews on slots – We recommend you check out KingCasinoBonus.uk regularly to see if we cover the slot game you are looking for in our blog. We use our expertise and report to you any findings, so you know what to expect beforehand.
4. Gain experience yourself – New slots are always coming out, so if you enjoy the mechanics, you can try out different sites we have vetted. You’re ensured that they’re up-to-date with the latest advancements in all things slots, and also offering fast withdrawals on top of that.

New Slots Sites with No Wagering Offers in 2023

Check for a no wagering bonus at your new slot site, even though it requires a top-up and, sometimes, spend of your deposit, this is a much better deal – while you might have to deposit to claim the extra funds, you’ll be able to keep all you’ve won. In other words, say goodbye to wagering requirements.

Some great examples Betfred’s best £10 deposit bonus in the UK with 200 no wagering spins. Other must-grab options include Virgin Games’ 30 no wagering spins for 10 pounds or Monopoly Casino with a similar bonus.

Spot New Independent Slot Sites

One common misconception is that new slot sites mean new operators. To avoid this mistake, consider these scenarios, which would make a slot site completely new:

We rarely see a slot site launch that is genuinely new and independent of existing platforms or operators. Obtaining a new UK Gambling Commission license and launching their brand for the first time is not always easy for new companies which are just starting up.

• Existing Operator Launches New Site: Established and successful iGaming operators sometimes launch an additional new site on their existing proprietary white-label casino platform. While the company isn’t new, the site represents a new brand under their umbrella. An example is Pub Casino from L&L Europe.
• New Skins for Existing Platforms: The operators behind these sites may or may not be new, but an established white-label platform provides casino software, management, and licensing.
• Sportsbook Adds a Casino Section: Some operators providing sports betting services, expand their brand by including online casino games. This trend became increasingly popular in 2022, and it keeps on growing. Thus, when sports betting sites launch a new gambling platform, our experts consider it a new slot site worth reviewing.
• Platform Changes: When gambling operators decide to terminate one platform to relaunch it using new software, it creates an essential new slot site – even if the brand and the games remain the same. As player bases don’t transfer over, these sites allow players to claim welcome offers again.

Are all the slot sites 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 casinos for them.

Why Play on Mobile?

Most new online slots are better for mobile play because they are designed mobile-first. Naturally, you can play them on a desktop as well.

Where to Find the Best New Mobile Slots

Aztec Wins Casino is a newly launched slots site that offers over 1,500 slots, varying in RTP, number of paylines, themes, and features. You currently won’t be able to download an app, but you can play all games on your mobile device.

We’ve picked Aztec Wins as a leading mobile-optimized slot site due to its variety of choices, simple interface and themed look. Alternatively, check below for more recommendations.

UK’s Newest Slot Sites vs Established Sites

Payout Rates in Brand New Slot Sites

Payout rates in new slot sites offer a general idea of how much the slot pays out over time. But high RTPs alone don’t guarantee profits, which is a common mistake new players fall for. 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 2023

If you are looking for a reliable list of high-RTP slots to play, our experts have analyzed new and established slots from an RTP perspective, and settled on the highest-RTP new slot games you can play this year:

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.

Return-to-Player percentages for new slot games can vary between one casino to another, as operators are allowed to set a specific percentage. However, legally, whenever a slots’ RTP is changed, the operators will update the value on their website.

The RTP percentages you see at the time of publishing on casino or provider sites are considered accurate. But keep in mind – RTPs are not stagnant and can fluctuate – especially in your experience as a player.

New Slots from Established Providers

Following a similar methodology, here are our favorite new slots from established online suppliers like NetEnt, Microgaming and Pragmatic Play.

New Microgaming slots

Microgaming casino UK sites are also known for the jackpots they provide on the Mega Moolah progressive network.

Microgaming is a pioneer in the slots industry and a key provider at UK casino online sites, known for its excellent additions to the Megaways slots. Immortal Romance, Mega Moolah, and Thunderstruck II are only some of their best-known releases.

Pragmatic Play new slots

Pragmatic Play is among the leading mobile slots providers, best known for their Peaky Blinders, Wolf Gold, Great Rhino Deluxe, and Jungle Gorilla gems:

• Big Bass Splash (extra spins bonus round)

Discover New Slot Game Providers in 2023

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.

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, Play’n Go, NetEnt and Playtech.

What Payment Methods Can UK Players Use?

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 2023.

KingCasinoBonus experts recommend finding a top PayPal casino like the VIC to play new slots. 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-£30.

Licensing of New Slots Casinos in the UK

The question on many responsible players’ minds in the UK is: do all new slot sites have a valid UK licence? You know for sure that our recommended new casino slot sites hold a UKGC license.

Are the newest slot brands safe and trustworthy?

All the newest slot sites recommended on our page hold valid licences from the UK Gambling Commission. As experts, we thoroughly vet and review each new casino before listing it here. Our priority is player safety and security.

We carefully inspect the licence of each site and confirm the UKGC approves it. Our testers will not proceed with further review until the licence is verified. We also check for additional security measures like SSL encryption, secure document upload links, eCOGRA certification and more. Rest assured, all the new casinos listed here are licensed and secure for UK players.

How We Research New UK Slot Sites

Besides licensing checks, our team of experts rated and reviewed the latest UK slot sites on the market using manual testing and new selection criteria based on the availability of

Mobile Compatiblity

We compare all the new slots sites’ performance with our best UK mobile casino apps, and only select the ones which work well when compared to our best casinos for Apple iOS and Android smartphones.

New Slot Selections

We then continue to thoroughly test the slots section, looking for newly added slots. Our testers also take into consideration the game providers as well as their reputations.

New slot sites in the UK are rated better if they collaborate with multiple software providers rather than just one. Finally, we ensure there is a slot variety and that all games are fair.

Game Variety

After checking the slots, we ensure the sites have enough game variety in the rest of the categories. Even though slots are the main focus, the site should at least provide table games. New slot casinos that offer a live casino section are rated higher than those that don’t.

Bonus T&Cs

Out of the 5 testers assigned to one new casino entry, two claim the bonuses and test the games, trying to clear the wagering requirements. If all goes well, we will make sure to rank the casino accordingly.

The rest of the team concentrates on the T&Cs to ensure that the rules of the casino are fair and that you’ve got an actual chance with the bonus.

Payment Options

Once we’re done playing with the bonus funds and testing the quality of the games, we make sure to test the Cashier section first-hand. We do that by requesting a withdrawal through multiple payment methods. We also use this opportunity to check for hidden fees.

To do so, each tester uses a different deposit method to be able to test the withdrawal times of various options. We give good ratings to new slot casino entries that abide by their advertised cashout times.

Responsible Gambling Tools

Responsible gambling is our first priority, which is why we make sure that each casino has enough measures in place. We set our deposit and wagering limits and timed the gaming sessions to check how the operator handled the helper tools.

Customer Support

Lastly, we make sure to inspect customer service and see whether it is possible to obtain a viable answer. Each of our testers sends inquiries through different contact channels, and we rate the friendliness and the time of answer. We’ve given a higher rank to those with real-agent live chats.

KingCasinoBonus Predictions for Next Year

The online casino space is constantly evolving. As veterans of the iGaming industry, with over 6 years of experience, KingCasinoBonus.uk experts have tried to gauge where the slots space will be in a year from now. Here are some of our predictions for new UK slot sites that may launch in 2024:

• More independent slot sites – With standout success stories like Luck.com in 2023, we think more independent platforms will pop up, rather than white labels.
• More free spins on registration – To attract new signups, new sites may offer 30, 50 or even 100 spins as part of the welcome bonus. More and more casinos are trying to sample their platforms and services using these bonuses.
• Low minimum deposit deals – More £5 deposit bonuses and potentially even lower minimums like £3 or £1 will appear, in order to appeal to casual players. The gambling space is more and more inclusive for lower budgets, compared to what we saw in 2017 when we started our journey.
• Focus on mobile optimization – New sites will be mobile-first with intuitive design and features for iOS and Android. It is rare today that we see a new online slots UK website that is slow, lags, or has serious bugs.

Why Play at New Online Slot Sites? Here’s Our Verdict

Our experts, Ionut Catalin Marin and Vlad George Nita conclude that new slot sites are worth playing at for their more generous signup bonuses vs established sites. You also get innovative new slot special features rarely found at established brands. While new sites carry some risk of unproven trustworthiness, KingCasinoBonus has verified them all for your security. The most competitive and fresh new slots casinos cater to mobile users with optimized sites and apps, collaborate with cutting-edge studios like Red Tiger Gaming or Eyecon, and offer speedy withdrawals through e-wallets like PayPal. What makes new casino slots sites compelling or at least worth considering is that they go above and beyond to add as many as 15+ new online slots every month.

Pros and Cons of our New Slot Sites 2023 UK

Pros

• New online slot casinos are the best places to find new no deposit offers for the latest games.
• You have the chance to play newly released slots from top-end providers.
• The Promotional section is brimming with bonus deals for new players.
• Faster withdrawals may be attainable.
• You’ll find modern payment options, and most are casinos with PayPal support, as well as other e-wallets.
• New slots casinos are better designed and fully mobile-compatible.

Cons

• The operator may be new, so there’s no way to confirm the trustworthiness,
• There may not be a VIP program yet.
• The new slot site may not have a native mobile app yet.

Safer Gambling

Keep in mind that at KingCasinoBonus, we only recommend new slots casinos prioritizing ethical and responsible operations. All new slot sites we vet must adhere to strict standards for promoting responsible gambling, just like established brands, as the rigorous UK Gambling Commission licenses them. Because of this, you can enjoy their latest games, knowing safety features are in place.

New platforms offer responsible gambling tools like:

• deposit limits
• loss limits
• reality checks
• self-exclusion options.

The UKGC licensing mandates providing resources to play safely, especially self-exclusion. Most brand new slot sites we picked on this page go beyond this and offer resources for problem gambling prevention, like timeout periods and self-assessments.

If you feel you have little to no control over your gambling habits, self-exclusion comes highly recommended. In the UK, players can go the extra mile and sign up for Gamstop, which self-excludes you from every website you have an account with.
