There are a number of reasons why you might choose new casino sites in the UK over more well-established ones.
To start with, let's talk about what qualifies as ‘new'. For us, it’s any casino that was founded within the last one or two years.
With this in mind, new casino platforms are more likely to give a big welcome bonus, implement the latest iGaming technology, and have seamless mobile compatibility.
Tech moves fast, so each year there are new ways to create a more engaging, smooth and secure user experience. This is exactly why new gambling sites are so popular.
By choosing a new casino, you can gain access to never before seen features and impressive bonuses. So let’s investigate how we choose the best ones.
As one of the top casino comparison sites for UK players, we have a lot of casinos to choose from.
And, we are constantly on the lookout for new platforms to add to our lists.
We pride ourselves on our ability to find the very best casinos, but it isn't always easy! Narrowing our selections down to just a top ten or top twenty is tricky, especially when all of the casinos we recommend are excellent.
To help us make the decision on our top 5 new casinos, we scrutinised each site on a checklist of different features.
All of the casinos that we chose are new to the industry, and stand out from the crowd in at least one other area. That could be instant withdrawals, super fast verification, massive bonus value, or a bumper games catalogue.
Here are our top 5 new online casinos:
All of the casinos on this list pass our basic checklist.
They’re all licensed by the UK Gambling Commission, safe to use, offer a great selection of slots, and have fair bonus terms.
However, these new casino sites have also gone through extra scrutiny.
We compare them side by side with the more well-established casinos that we trust – and make sure they live up to our very high standards. It’s important for us to be tough on new casinos as the real customer experiences that they have are limited.
The good news is that all of these recommendations passed our tests with flying colours.
So, let's take a closer look at our top 5 new casino options for UK players.
Players in search of a new casino that has a fantastic selection of slots and casino games will love Mega Riches, which comes with thousands of online slots, table game and live games to choose from. Alongside this, new depositing players can receive a 100% deposit match bonus and an additional 50 free spins.
Wild West Wins is one of the most recent additions to Hideous Slots, but it's one of the best – particularly for players looking for a low cost option. This casino not only offers a superb selection of slots and up to 500 free spins, but it also offers all new players 20 spins on Cowboys Gold free of charge – no deposit required.
Bally is a household name in the UK, which is why this is one of our favourite new casino sites for UK players. By depositing just £10, all new players at this casino can claim 30 free spins with no wagering required on winnings. Additionally, this fantastic site offers hundreds of slots and a variety of casino games.
NRG.Bet is a fantastic and fresh option for players who like to find a new casino that operates as a sportsbook also. This great casino not only offers hundreds of slot and casino games, but also up to date odds on a variety of sporting events. To make things better, all new players can wager £25 and get 80 free spins.
Midnite is a great all-rounder casino for UK players looking for a little bit of everything. With hundreds of slot games, live casino games and quick withdrawal methods, the only thing that makes this new casino site better is the welcome offer – 100 free spins on one of the most popular online slots, Big Bass Splash.
If you're wondering why you should be choosing new casinos over more well-established ones, then you aren't alone.
There are more players than ever now asking this very same question; why should I choose a new casino over an established brand?
New online casino platforms can offer you a multitude of improvements over established brands, and part of the reason for this is that they're new – so they have to stand out.
You're more likely to get a bigger bonus, a slicker, more modern user interface, a blisteringly fast mobile app, and access to the newest game releases. Older casinos don’t always have that same drive to compete, so why not make the most of it?
Here are our top 5 perks of a new UK online casino:
One of the things that you should be worrying about when playing online is your safety.
Some new casinos are unscrupulous, but most importantly some are unlicensed.
We will never recommend you a casino unless it has a licence from the UK Gambling Commission.
This represents the gold standard in industry licensing, so you not only know that it’s safe and legal, but also that it’s properly regulated, and tested for fairness.
Simply by holding a licence from the UKGC, you know that a new casino site is safe to use. We go one step further in our reviews and recommendations though.
We also rank them based on what we think is fair. From high payouts to transparent bonus terms, all of these casinos pass our fairness tests.
As a new player signing up to any casino, you’re in a great position – you can claim any welcome bonus that you like. This is a great way to be rewarded for your custom at an online casino.
New online casino sites often have better value bonus offers than established casinos and sometimes fairer T&Cs too.
It’s important that they work harder to gain the trust of us players, and let us know that they really do provide the best bang for our buck.
This means that you can double or even triple your deposit, unlock hundreds of free spins and even take advantage of offers with no wagering attached.
There are a number of different deposit bonus offers you can find at online casinos, but they all fall into one of the following categories.
Tip: Because you’re playing in the UK, all of these bonuses are ‘non-sticky’. This means your cash balance can be withdrawn at any point and T&Cs won't apply until you have used your bonus or are in bonus funds.
Deposit match bonuses are the most common offer you will see at any UK casino – new or established. These offers mean the casino matches a percentage of the deposit up to a certain value, awarding bonus money (with T&Cs attached), which players can use to play their favourite games.
Free spins bonuses are the perfect option for players who love playing online slot games. These rewards will see players receive a number of free spins for use on popular and new games; this may be less free spins alongside a deposit match, or hundreds of free spins as the whole offer with T&Cs.
Wagering is one of the most tedious parts of the terms and conditions attached to any online casino bonus, but thankfully there are a number of new casinos offering no wagering welcome bonuses, which consist of a number of free spins with no turnover required – you keep what you win.
What better way to be rewarded than with a bonus that doesn't require any financial commitment from you upon sign up? No deposit bonuses allow players to claim small rewards, completely free of charge with no T&Cs – these are usually awarded just for singing up to the casino.
Variety is the spice of life and welcome packages are the spice of the online casino bonus world. These offers are multi-tiered, which means players can continue to be rewarded across consecutive deposits, triggering any combination of the bonus offers mentioned above.
There's no reason the rewards should stop after you've signed up, which is what ongoing perks and rewards are for. These offers are awarded to loyal players who continue to use the online casino in question, and can include the bonuses above or unique offers, like cashback or wheel rewards.
Defining a new casino isn’t as straightforward as you might think! Some casinos seem new, but can turn out to not be quite as new as they seem.
Mega Riches is a great example of this. It's our favourite casino, and it was new not that long ago. But, it's owned by Videoslots, who already owned the aptly named Videoslots casino and Mr Vegas, which came later.
This means that although you’re signing up to a new casino, you’re still signing up to a brand whose reputation precedes it.
On the other hand, new independent casinos are those who are brand new to the gambling scene and do not belong to a larger group.
Although you might be wary of this and the idea of a group reputation might appeal to you, remember that if it has a UK Gambling Commission licence it's safe to use – and actually many independent casinos offer the best bonuses for UK players.
So, you've signed up to the best new online casino and you want to know how to ensure you walk away with a cash out.
Well, we can't guarantee you a cash out, but we can give you our best tips to follow when playing your favourite games at a new online casino.
If you follow these tips, you'll get the most value out of your deposit (or deposit bonus), extend your playing time, and hopefully increase your chances of winning – yes, it is possible.
Here are our top tips when playing at a new casino:
Choose one of our recommended new casinos and click the link to visit the casino with a lucrative welcome offer locked in waiting on you.
Click register, provide all the details you are asked for and set a password. Ensure you provide your personal details accurately as they can be hard to change later.
Choose from any of the payment methods available at the new casino site you have chosen and make the minimum deposit to claim the bonus.
After making your instant deposit you just need to browse the game selection, choose a high payout release that will provide entertainment, and start playing.
With so many casino comparison sites available online, you might find yourself wondering why you should choose your new casino site through Hideous Slots?
Well, we're not only experts, we’re players too.
This means we’ve got the inside scoop and personal knowhow when it comes to all things gambling and casino. We use guides like this to pass this knowledge on to you.
Our team of casino reviewers and content writers have decades of experience in the gambling industry, which means we're well positioned to spot the best casinos with the fairest T&Cs and most generous bonus offers.
We’re asked to review a huge selection of casinos, but not every site makes the cut!
We put the time and effort in to make sure that when you sign up to one of our casinos, you’ve got all the information you could need. Our comprehensive casino reviews are only written after a casino passes through our stringent checks and testing.
We've been doing this for a long time, which means we have access to exclusive offers at the casinos we recommend.
So, if you sign up through our links, you can get a bigger bonus reward or more favourable bonus terms than if you signed up elsewhere. Sometimes your free spins are awarded on better games too.
We aren't just expert reviewers, we're pretty keen players as well!
This means that the casinos you see listed on our website aren't just ones we deem good enough for you – they're good enough for us too.
On our YouTube channel, our streamers play at the casinos we recommend, which allows you to see exactly how these casinos work in real time; how quickly the games load, how easy payments are, and even the selection of slots available to use your free spins on.
We also have a number of social media platforms where we interact with thousands of you, and even a website forum where our community gather together to share their big wins, discuss their favourite new casinos, and even debrief on the latest regulations in the UK.
These are the reasons you should choose your new casino through us – where else will you be able to experience every aspect of a casino in real time before you sign up?
The process for us to review a new casino is a rigorous one, broken down into a number of different categories – each as important as the last.
The proof is in the pudding; just like how we have some of the most in-depth slot reviews online, each of our casino reviews give more information than most.
Whether you want to know the minimum deposit required to claim an offer, how much wagering you must complete, the expiry of your bonus or even how you submit your verification documents, we tell you all of this.
We go to great lengths thoroughly testing each new casino site we consider.
In the process of reviewing the latest online casinos and bonus offers available to UK players, we look at the following categories.
Getting things off to a fairly easy start with safety and licensing. We only review casinos that have a licence from the UK Gambling Commission. No licence, no dice. A UK Gambling Commission licence is a guarantee of player safety and game fairness, so for us, it’s a non-negotiable factor in the process.
We want all of you to be properly rewarded for signing up to one of our recommendations, which is why we only recommend new casinos that offer welcome bonuses like cash or free spins, as well as ongoing perks and loyalty rewards like reload bonuses, cash-back or tournament prizes.
We only review and recommend new casino sites that offer round the clock player support. This can be through live chat, email, socials, or a phone number – and better if it’s more than one of these. We also look at the times this is available, how straightforward it is, and if there are additional features, like FAQs.
Most of us use our phones when we want to play online. So, we prioritise any new online casino that offers a dedicated mobile app, or a particularly slick mobile site. You should be able to do all the same things on your mobile as you do on your desktop – and maybe snag a mobile bonus too.
Now it's onto the fun bit. Finding a great new online casino also includes looking at the selection of slots available. Every casino we recommend has a large selection of slots that is regularly updated, with classic options alongside the latest released slots, all from a variety of popular game studios.
After considering the selection of slots, we look at which casino games are available. Ideally, the best new casinos should have a selection of table games, live dealer games, and live casino game shows from the most popular providers (like Evolution), offering something for everyone.
If you haven't figured it out by now, the safety and security of our players is a number one priority for our team here at Hideous Slots, which is why no new casino site will pass through our checks without offering a variety of secure payment methods to suit the needs of every player.
Offering secure payment options is only half the battle. We also expect each of the top new online casinos that we recommend to offer at least one fast withdrawal method. Ideally, we look for instant e-wallet payments and speedy debit card options like with Visa Fast Funds.
Although it's not a deal breaker, we pay attention to any brand new casino site that offers sports betting on their platform. By finding a casino that offers everything in one place, you can keep things simple by just having one account – and it adds variety like table games, live casino games and live game shows do.
On your quest to find the newest online casinos, you'll probably pass by a lot of established casinos and find yourself wondering why you shouldn't just join those.
There are a number of differences between new and established casinos that it pays to be aware of.
On the one hand, new online casinos are fresh, exciting and interesting. On the other, established casinos are comfortable and familiar.
You're no more likely to win or lose at a new casino as opposed to an established one, but the user experience you receive can vary quite a bit.
Remember, new casino platforms have to try a little bit harder to attract players, so they're more likely to be offering better benefits and bonus rewards.
New Casinos
Established Casinos
Not all casinos are made equal.
You should always be looking for safety and security in your online gambling ventures. So, there are a number of casinos you should absolutely be avoiding – those that are not licensed.
There's an increasingly common feeling amongst players that the UK Gambling Commission have gone a step too far with their regulation, and this can lead to players considering taking their custom to black-market, unregulated brands.
However, the UK Gambling Commission is responsible for more than just what you see.
They're the ones who make sure you get paid out, that you get your winnings promptly, and that you have access to responsible gambling tools and independent dispute resolution if it's needed.
You should always avoid a new UK online casino that does not boast a UK Gambling Commission Licence.
Hopefully you agree that we can write a great casino review by now.
But, we aren't just great at reviewing the online casinos that are already out there, we’re also pretty good at predicting what we can expect from the future.
One thing is for sure, online gambling isn't going anywhere. We only expect the popularity of new online casino sites to continue to grow in the coming years.
As this popularity continues to grow, there are a number of trends that are being predicted – ranging from the fairly obvious, like increased withdrawal speeds and new slot games, to the slightly more interesting, like artificial intelligence and virtual reality making their way into slot and casino games.
Here are the things we continually see predicted for the future:
There are a number of different tools available at both established and new casinos in the UK to help you to stay responsible when gambling online.
These tools exist to help you stay in control of your spending and time, ensuring your gambling remains a fun hobby, rather than a chore, or a bad habit.
By utilising these tools as preventative measures, you can get a head start on any potential problems, catching them before they begin.
In particular, the best new online casino sites offer a huge selection of responsible gambling tools, including the following:
Additionally, any good UK licensed casino will be partnered with GAMSTOP and Gamban, which allow you to block access to online gambling products easily.
New casino, new payment method?
There are always a variety of payment methods at any online casino, and a brand new casino is no different.
Choosing the right payment method can have a pretty big impact on your gambling experience, shaping the kind of bonus you can claim, the terms you must adhere to, your withdrawal time and even how low the smallest deposit you can make is.
Doing some research on the payment methods on offer to you will be incredibly beneficial, letting you curate the experience you want.
Across almost every new online casino in the UK, you will find a variety of unique payment options split into the following categories, each with their own benefits and drawbacks.
Debit cards are arguably the most common payment method used at new online casinos by players in the UK. Combining convenience with ease of use, debit cards users with access to Visa Fast Funds can see their withdrawals arrive in 2 hours or less – an added bonus to an already popular method.
E-wallets might not be brand new, but they're one of the newest payment methods you'll see at an online casino in the UK. Encompassing a range of products like PayPal, Skrill and Neteller, e-wallets are popular because they offer fast payouts and an extra layer of privacy for players.
Bank transfers are the most traditional, the most secure, and, unfortunately, the slowest. If you’ve got a particularly large deposit or withdrawal to make then bank transfers can be a good option. Otherwise, it’s normal to gravitate towards debit cards or e-wallets so you don't have as long a wait for your money.
Prepaid cards like Paysafecard are growing in popularity. They offer increased privacy and the ability to manage your spending with ease. As you need to top up the card or buy a voucher online, it’s an easy way to keep track of how much you’re spending, but the drawback is that you can't withdraw to a prepaid card.
If there's one way really exciting way that we're seeing new features being implemented in new casinos, it's through social interaction.
Not only is this more fun, it’s helped to move online gambling away from being considered a solitary activity.
More and more people are gambling online now, and communities are being formed across the internet – including our Hideous Slots community.
These communities have members from across the globe sharing their latest wins, near misses and their thoughts on the latest online slots and slot sites.
New casinos are aware of this, and so they've started to introduce social features to their sites.
You can find tournaments where you can compete against each other, live chats to keep up to date with the rest of the casino community, and real-time leader boards so you can see what your friends win, and on which games.
In the online gambling industry, things are changing every day.
For game studios, it’s important to follow trends and innovate to keep things fresh.
As a player, you get to reap the rewards of that by having access to brand new online games that are completely revolutionising the casino experience.
Some of the latest features available on online slots would never have been seen on classic slots, and are great examples of how far game production has come.
Here are some of the newest slot features you'll see:
In the past, online casinos just weren’t as popular as the land based alternative.
Heading out to the casino was a social event and the internet was still a relatively new-fangled thing – hard to imagine now, we know.
Players preferred the comfort and safety of what they knew and stuck to the tried and tested brick and mortar establishments.
However, as the offering at new online casinos improved, more and more players shifted their play online. One of the things that really kickstarted the online casino revolution was live casino games.
These are so common now that it’s hard to remember online casino life without them.
New live casino games replicate the true casino experience. You can play all of your favourite casino games, chat to the live casino dealer and chat to the other players too – all in real-time. And all without leaving your living room.
The online casino landscape is ever changing. Sites battle to offer the best experience to us UK players.
New platforms come and go, but the best new casinos? They stick around.
These new casinos bring innovation, unique gaming portfolios and impressive bonuses.
Alongside them are some of the most established brands worldwide; those that have spent years earning our trust and loyalty.
Thankfully, the UKGC does a great deal of your scrutiny for you, and we do the rest. If a new online casino site has been afforded the UKGC licence and the Hideous Slots seal of approval, you know it’s safe, secure – and great fun too.
Whether you’re a new player looking for new online casinos in the UK or you’ve been here for years and you’re just looking to shake things up, UK players are spoiled for choice now more than ever.
If you enjoy larger bonuses, faster cashouts and more lucrative ongoing rewards then new online casino sites are the smart choice. Many of them have a sleeker user interface, a better mobile experience and invest in new iGaming tech. All of this means a better experience for you.
New casinos pop up all the time. So, it’s hard to say which is the absolute newest . However, from the new casinos that have passed our extensive testing, Wild West Wins is the newest. We’ve only recently added this new casino to our listings and we love what it has to offer.
It all depends on what you’re looking for! Some sites offer enormous slot catalogues, others have bumper bonus selections. One thing you should always look out for is a licence from the UK Gambling Commission. These casinos are guaranteed to be fair, safe and secure, and will reward you with a welcome bonus for signing up.
We’re pretty good, but even we can't measure how lucky a casino is! You can maximise your chances of a payout by choosing a new online casino that offers games with high RTP percentages, good value bonuses, and high payouts. Mega Riches is new to the market but already ranking highly among our readers.
New casino technology encompasses every advancement that casinos are using. While you tend to find more new casino tech at new sites, sometimes more established brands implement it too. Everything from AI customer support to virtual reality and multiplayer games is considered new casino technology.
New casinos will often offer faster payouts as one of the perks that sets them apart from the competition. It’s a crowded marketplace, so being able to offer speedy payouts is a big benefit. Mega Riches processes all withdrawals within 5 minutes and Midnite offers a variety of fast payment options too.
If you use one of our recommended new UK casinos, then yes. We guarantee it’s completely safe to join, as all of our recommendations boast a UK Gambling Commission licence – a hallmark of safety. However, if you’re researching your own then be sure to check for a UKGC licence, without one, a casino may not be safe.
Yes. In fact, new casinos will also often offer more lucrative bonuses than their older competition as they need to encourage players to join; like Bally Casino, which offers free spins with no wagering, or LottoGo, which offers a 100% match bonus.
New casinos sometimes take a while to fill out their game catalogues, but when they do, you can guarantee it’ll be with the latest releases. Expect to find games from all the usual categories (slots, table games, instant wins, and live casino titles). The other big benefit is that because the catalogues update regularly, you get access to all the newest slot games.
The golden rule is to only ever choose casinos that have a UK Gambling Commission licence. If a new casino site pops up but it doesn’t have a licence, then don’t be tempted to sign up. The only way to guarantee the safety of your hard-earned cash, is to look for that licence. If you’re struggling to find a new casino you trust, then scroll up to find one that our team have certified as safe.
