How we make money
CasinoAlpha has a paid partnership for product placement with all the online casino operators listed on the site. Similarly, we receive money from our partners whenever our users click on certain links. Such compensation does not influence our recommendation, advice, reviews, and analysis. We remain unbiased no matter the collaborations we have.
We’ve tested over 90+ new casinos on the UK market and spent over 260 hours analysing them to bring you the top new online slot sites available today!

Why you should trust us
In its effort to incentivise enhancing the online casino quality standards in the UK, CasinoAlpha generated a testing protocol designed explicitly for slots sites.
At least three independent contributors will check all essential areas of functioning for all checked and featured platforms, this being how we review casinos in general. In the case of slots sites, we prioritise aspects specific to the game type:
The number of slots on the site.
The game providers behind the titles.
RTP rates and volatility.
Reels, paylines, and in-game bonus features.
Transparency in communicating game specs.
Interface quality and fidelity.
Bonuses dedicated to slots.
Game variety and presence of jackpots.
Promotional policies for slots.
We use our expanding database of 240+ casinos to create a dynamic and trustable standard that reflects the state of the UK market.
CasinoAlpha found the following qualities to be necessary for slots sites:
Ideal for British Slot Sites:
Number of slots: 1000+
Provideris: 5 or more renowned providers
RTP rates: Aboveabove 96%, 99% included
Reels, paylines, features: More variation
Game spec communication: Specs immediately stated
Interface and performance: Well-performing and pleasing
Wagering contribution: 100% for all non-progressive slots
Jackpot availability: Jackpots and progressive jackpots available
Beyond the reviews that communicate all relevant aspects succinctly, according to our editorial policy, we generate ranked lists for slots sites that perform exceptionally well in one area:
Sites that include a specific popular title
Casinos that host a provider’s catalogue
Newly launched UK slots sites
Platforms with particular bonuses, like free spins
And more.
How did we test slots sites?

We filtered our complete database to get newly released sites with slot games.
From a selection of 100 casinos, we ran multiple tests to verify the quality of the services inside out.
The first test stage takes +12 hours and results in our casino review.
The second test stage takes +10 hours and adds a site to this page’s list.
Tests are run by at least 3 people using 3 types of devices.
On average, each CasinoAlpha team member deposited between £15 and £35 for full access.
On each option, we played a minimum of 10 slot games.
We’ve always tried to advance to the cashout stage. We got there about 20% to 25% of the time.

How we select & review the best new online slots sites?
To create this page, we have followed our usual two-stage strategy. Here it is:
Preliminary stage
To publish any review on CasinoAlpha, we sign up for a new player account and complete all the necessary steps to have full access to the site’s features.
These features are submitted to multiple tests for:
Data security
Loading speed
Usability
Game catalogue variety
Bonus terms
Payment options
Customer service
After the test results, we give ratings and set the casino between the market average and competing sites. The first stage is, at this point, complete.
Main stage
To add any operator on this page, we compare multiple features to create unbiased tops.
Casino features we compare:
Objective player options like number of games, number of game providers, number of payment options, and the existence of fees.
Subjective player options like graphics, theme, usability, and the attitude of the support agents.
How do we conclude the process?
Once it is proved that a site has both objective and subjective features at an above-average level, we can integrate it into our curated top.
We focused mainly on the slot options at hand. We looked for a large number of games, different thematic to each, customizable settings, and, eventually, associated bonuses. That happened in the usual framework that we apply to the best online casinos, namely licensing and all the guarantees, good user experience features, fund protection and responsible gambling methods.
Since we want to be transparent to our UK users, we will take each casino one by one and present them through the lens of their best slot-related features.
Royale500 – thousands of slots on a new site
Currently, this site has the most games from top providers like Microgaming, NetEnt, Play’n GO, and 30 others.
No cashout limit means your possible jackpot sums are not capped.
Popular games, such as Starburst, are found on the front page.
No charges on bank cards or e-wallet transactions.
Wild West Wins – a hub for slots
It takes just a couple of minutes to create a new account and access the more than 1400 slots.
Some popular providers sponsor the slot pages, as well as more nuanced options like Eyecon or Wazdan.
The accepted bet limits go from a few cents to sums of around £25, meaning they fit all budget ranges.
Some slot games are included in “daily tasks” that, when completed, unlock unique casino bonuses.
SpinYoo – a slot experience walk-through
Our review gave this casino a high game score for usability and variety.
Games can be filtered by their type, how popular they are on that day, or how new they are.
By our calculations, the average RTP, over all that catalogue, is above 96%.
Over 90 providers in total are partnered with SpinYoo.
Buffalo Spins – a solid option for UK players
The site’s main focus is slot games, to the detriment of varied Table Games.
We found 6 slot categories, so it is easy to find your favourite game or get to know a new one.
We found famous names like Microgaming, NetEnt, Pragmatic Play, and Yggdrasil from the providers listed.
Deposits associated with slots may open up new gaming opportunities.
Barz – a new trending slot casino
We found diverse titles through our research, from things such as Starburst to movie-themed games.
The slot listing has a dedicated “Drop & Win” category.
The lobby allows users to apply filters to find games that fit their standards.
Almost 100 partnerships with game software companies.
Why play on new slots sites as a UK gambler?
They are a revised version of older, well-established slot sites.
Since online slot machines are the most requested game category, many casino bonuses are associated with newly released slot casinos.
You are more likely to find state-of-the-art games that have advanced technology. Those bring new game opportunities.
To cater to the needs of gamblers, these online casinos will focus on the slot catalogue available first and other games afterwards.
Over 90% of the websites we have investigated are easily accessible on mobile; thus, we also add them to our latest mobile casinos selections.
Some of them are created by established operators with higher ratings in casino review comparisons, as opposed to others.
We have curated information and specialised promotions regarding NetEnt games in our NetEnt free spins UK list, which we update monthly.
We mentioned Book of Dead in our table, knowing the predilection that UK players have for the game. We discovered all that when we selected over 600 Book of Dead free spins no deposit.
Advice when you’re playing these games
You can protect your budget when you’re engaged in a free spins no deposit type of promotion.
Slot games are fast-paced, so make your sessions shorter and the breaks between them longer.
Games are highly optimised on smartphones through the casino app version rather than the browser version.
Check if the online casino has not changed the general provider-driven RTP. Sites are allowed to do that, and sometimes they make changes of the sort.
When you are in the process of completing bonus wagering, games like these are the ones with the highest contribution.
Staple game providers for brand new slot sites
Microgaming: established in 1994.
NetEnt: established in 1996
Pragmatic Play: established in 2015.
Game providers sought-after on new slot sites must create engaging games continuously, and they have to be as diverse as possible. That goes for everything from graphics to game settings, game volatility, and outcomes.
There are over +200 providers that populate the market. However, the podium that we have presented to you has proven to have a good reputation and a good product catalogue.
Tips
We will update our choice when significant changes happen in the trends and predilections.

Important
Note that, on average, the RTP of progressive or jackpot games is lower by default. That is tied to general game engineering, as the chances of positive outcomes are smaller.
Bonuses for the best new slot sites
One fundamental recommendation we have is to link your slot sessions with a casino bonus. We will briefly present each one and how to use them.
Free spins on new slot sites UK – the best pairing
Free rounds are specially designed for online slots. They are basically rounds in the game that don’t decrease your budget.
To pick the right typology for you, take into consideration your time, particularly when calculating the wagering timeframe.
Minimum deposit slot bonuses – accessible with small payments
New slot minimum deposit casinos are a valid option, mainly because they come from well-known operators, guaranteeing a satisfactory catalogue of games.
Important
We have discovered that small sums dedicated as bonus funds are locked to play on slots exclusively. That means that they comply with the needs of gamblers.
No wagering options on new slot sites
Even if no wagering bonuses have a rarer frequency in the industry, most of them are locked on slot games or come from new UK slot sites.
Tips
Casinos usually send these opportunities at the end of a longer period of time, such as at the end of the week, fortnight, or month.
Cashback bonuses – a viable option
Cashback bonuses are rare to find, just like bonuses with no turnover attached. Even so, when they are delivered, they are associated with popular gaming categories, where online slots reign supreme.
Tips
As gambling experts, we know that these cashback offers are like a plan B when it comes to your fund management. They are calculated by the previous percentages of your losses, which means no additional deposit.
Be aware
Whenever you play with any CasinoAlpha bonus, read our bonus descriptions and then the full T&C text. Otherwise, you risk losing a bonus by unknowingly breaching the rules.
How to choose a site & sign up?
rgest part of the research and experimenting for you, so your first step is to choose from our options.
When making a decision, consider the minimum deposit required, allowed games, and the timeframe given to wager.
Always consider your budget and schedule when looking for a new slot site.
Click on the Play button near each bonus title.
Read the text on the landing page that gives you instructions for the next steps.
Follow the step presented, which usually requires you to sign up.
Signing up means sharing your data and contact options.
Most of the time, after signing up, you can make a deposit.
You’re all done and ready to play any slot game in their catalogue.
Recommendation
Sometimes, you need to confirm your phone number or e-mail before being allowed to gamble.
We recommend you save time right from the start and complete the KYC procedure after you log in for the first time. That makes the withdrawal process take less time.
Pro-tips for optimised play on 2023 new slot sites
Look and assess if the game selection and the list of providers are to your liking. Unless you find titles you like or want to try, it is not worth your investment.
Make sure to read our review and the site’s T&Cs to find out if there are any fees applied to your withdrawals. Most slot outcomes are not hefty, and fees may change them significantly.
Confirm if the customer support options work and give out genuinely helpful answers. Not having someone to answer or help may be problematic.
Choose casinos with a good reputation. That is easily discoverable by looking at the licencing and our reviews. We always take into account player opinions.
Whenever you can, look for rarer options for slot-related games, like free spins for adding card. Such offers break the monotony of the usual incentives.
Transactions management
Your budget is vital to your gambling experience. Thus, we want to share easy tips to deposit and withdraw correctly on brand new slot sites.
Making a deposit the right way
Your first step is to check if you can use popular UK methods. Amongst them, we recommend:
PayPal
Skrill Moneybookers
Neteller
Pay by phone
Note
Classic bank cards are still very popular in the UK, and we can confirm that you can use them on the sites we list here too.
Of course, you need to check if fees are applied and if the money landed in your account after you’ve made a deposit. Usually, that happens within a few minutes.
Important
Don’t use a payment service you are not familiar with. That may cause issues that are easily avoidable.
Making a withdrawal easily
Withdrawing should be requested when you have no pending wagers or previous transactions.
Then, you need to use a withdrawal method you’re comfortable with, with no fees attached.
You may see fees for:
Transactions smaller than £10;
Transactions over £100;
Multiple requests on the same day;
E-wallets
Pros and Cons
Pros
Satisfactory diversity when it comes to the slot catalogue, both in number and thematic
Partnerships with top game providers
Multiple bonuses available
Easily used via your phone’s browser or casino app
Early access to newly released games
Good user experience
Cons
Less jackpot or progressive titles available
Hard to judge the reputation by yourself
Limits when it comes to other gaming categories
Page methodology and resources

When it comes to the initial collection of options, we resorted to:
Our own database of UK operators

The latest directives in terms of data privacy
Our own experience as gamblers, knowing your needs firsthand.
F.A.Q
Are new slot sites safe?
Yes, as long as they are licenced actively by the UKGC, they are safe. All CasinoAlpha UK new online slots sites have the UKGC seal.
Are all online slots linked?
No. Certain online slots are linked in the sense that all the best made across all casinos that operate them raise the general total jackpot. That only happens with some progressive slots, like Mega Moolah.
Is there a winning strategy for slots?
Slots strategies have less to do with the game and more with money management. As long as you don’t bet your profits and don’t exceed your budget, you’ll be fine.
