The Latest Casinos on JohnSlots

We’ve seen plenty of new casino sites launch in recent years, and many of them have been to our standards and therefore included in our lists. But some of these new online casinos have gone above and beyond to offer players a superior experience in various ways.

Below you’ll find the latest UK casinos we’ve reviewed. Our writers spend 24+ hours on average reviewing and testing each casino to make sure we feature only the best ones.

Here’s a summary of the top 3 new casinos:

Betrino Casino

Betrino Games screenshot

Betrino offers an impressive gaming experience with over 2,000 casino games and a steady stream of promotional offers, but falls short in several key areas. While the slot selection from top developers like Games Global and Big Time Gaming is excellent, there are punishing 50x wagering requirements on most bonuses which we think can be improved. The 200% welcome bonus up to £50 sounds attractive but becomes less appealing when you consider the high wagering requirements and 3x maximum win cap.

Key Facts:

  • Over 2,000 high-quality casino games from renowned developers
  • Strong variety of ongoing promotions and weekly deals
  • Tiered loyalty program with missions and rewards store
  • Good mobile compatibility
  • Cashback offers with no wagering requirements

Monster Casino

Monster casino welcome offer

Monster Casino delivers a solid gaming experience with over 700 games from top providers, complemented by 24/7 customer support and strong mobile compatibility. The welcome package offers up to £1000 in bonuses plus free spins across your first five deposits, though like many of the newer casinos on the market, it comes with steep 50x wagering requirements. While the game selection is quality over quantity with excellent live casino options and bingo, the promotional offerings are somewhat limited compared to competitors.

Key Facts:

  • 700+ high-quality games from top slot developers
  • Comprehensive welcome package up to £1000 + 250 free spins
  • Excellent live casino and bingo options
  • 24/7 customer support available
  • Strong mobile compatibility with dedicated apps
  • Progressive jackpot slots available

Big Thunder Slots Casino

Big thunder slots casino welcome offer

Big Thunder Slots, launched by Jumpman Gaming in 2018, stands out from typical network casinos with its exceptional £6,000 welcome bonus package – unusual for Jumpman casinos that typically avoid match deposit bonuses. With over 1,000 games from top developers and low £10 minimum deposits, it offers solid gaming variety. However, the casino is significantly hampered by extremely high 65x wagering requirements and restrictive £250 maximum win caps that severely limit the practical value of bonuses.

Key Facts:

  • Generous £6,000 welcome bonus package across first three deposits
  • Over 1,000 games from leading developers (NetEnt, Pragmatic Play, Play’n GO)
  • Low £10 minimum deposit requirement
  • Wide range of payment methods including Pay by Mobile
  • UK and Alderney licensed and regulated
  • Regular promotions with cash prizes and giveaways

More New Sites on JohnSlots:

Our trained team of casino review experts at JohnSlots strives to bring you everything you need to make a decision on which new casino to play at. From unbiased reviews and opinions on the latest casinos, to up-to-date information on their welcome packages, promotions and everything in between, it’s all here, all in one place.

New Mobile Casinos

A quality mobile casino is becoming increasingly more important since many players are now expecting an experience that can be enjoyed on the go. We test all casinos on both iOS and Android, and ensure they have decent ratings from enough users, before we recommend them to our users.

New No Deposit Casinos

We love finding brand new no deposit casinos because well, it gives us a chance to try the experience for free without paying a penny. Check out our no deposit bonus casinos list, to see the latest entries. Such promotions are not easy to find, but JohnSlots often partners with brands to offer you special promo codes or free spins.

New Live Casinos

Some casinos spread their focus across a range of different gaming products. Particularly when it comes to live casino and authentic casino experiences, you want to find a great selection of games on offer.

New Game Providers

We always look for new casinos that offer a wide selection of new game providers, from established providers like NetEnt, Games Global and Yggdrasil to newer providers like Play’n Go, iSoftBet and Evolution Gaming.

New Casino Promotions and Offers

Constant updates of new casino promotions and offers keep players on their toes, and it’s very hard to get bored.

New Slots Sites

Casinos that primarily focus on slots are our favorite thing to test and review! These new slot sites offer a wide selection of games and slot-focused promotions, including Drops & Wins, tournaments, and everything else slot-related. We carefully evaluate each one that comes our way, scrutinizing it to guarantee it meets our high standards before it earns a place on our latest slot sites list.

🔒 5 Reasons Why JohnSlots is the #1 Source on New Online Casinos

We make it a point to test each new casino that catches our attention. In fact, we are a leading source of information on new online casinos for many reasons:

  1. We have 12 Expert Writers Focused on our User Needs.
  2. We have a proven track record of Over 1,500 Slot Reviews and 300 Casino Reviews
  3. We provide first-hand information after spending 60+ Hours of Work Per Casino Review.
  4. We do comprehensive research, spending £120 on Deposits and Playtesting per Casino
  5. We constantly update our 1800+ reviews.

Want to know more about our testing and data collection process, as well as the team who is behind all this? Here’s why you can trust us to provide you with the needed information on the best new online casinos:

1. We Focus on Our Users ✅

Our review team consists of 12 expert writers who know what online casinos are about. They know which features appeal to players and which are unimportant. Each review they create gives potential casino players information regarding the essential parts of a casino—the security features, casino lobby, promotions, and responsible gambling tools to help them stay safe.

We also know it’s impossible to review every new online casino as soon as it becomes available, so we have resources that players can use to review a casino and determine whether it’s safe for themselves. In the learning hub, you can find 70+ articles to help you cash out your winnings, determine which bonuses provide the best value, and so much more.

2. We Have a Proven Track Record ✅

JohnSlots is not a new review platform—we have already established ourselves as leaders in the iGaming market regarding current, unbiased, and accurate reviews of casino platforms and games. Our team of expert reviewers has already published over 120 casino reviews, including reviews of the latest casinos to emerge.

The writers work on 5 to 15 casinos a month but also focus on reviewing online casino games, usually testing between 10 and 20 slots in the same period. We are currently home to 1500+ slot reviews and over 1,000 demo slots that you can play for free. So, start reading our reviews and see why so many people use JohnSlots as their go-to source of online casino reviews.

3. We Provide First-Hand Information ✅

Unlike other casino review sites, we don’t use other people’s reviews to write our own. Instead, our team of writers does their own testing and analysis. This helps us ensure that the information we provide is accurate and timely.

The entire review process for a single casino takes around 60 hours. We dedicated over 15 hours to collecting and verifying data, along with approximately 8 hours researching all aspects of the casino. This foolproof process helps us create reviews with all the information you would ever need.

4. We Do Comprehensive Research ✅

You know what they say—the devil is in the details, so the best way to learn about an online casino platform is to review or research every aspect. We’ve explained that we spend hours on every review we create, but we also want to explain everything that goes into our research process. When we prepare for a new review, we test:

  • Licensing and security features
  • Casino lobby and game variety
  • Software providers
  • Bonuses and tournaments
  • Payment methods, times, and fees
  • Responsible gambling measures

We also test various other features and invest £120 at each casino to review the cashier, depositing and wagering process, and payout speed per payment method.

5. We Constantly Update Our Reviews ✅

We don’t see new online casino reviews as a one-and-done thing. We know that casinos, especially new ones, undergo a ton of changes based on user feedback, all in the hope of tailoring the platform to the users’ needs. So, we regularly visit the casinos to examine the changes implemented since the last time we tested. That way, we can provide you with information on all changes to the design, additions to the game library, or the availability of new bonuses and promotions. Most casinos get monthly bonus availability checks, during which we verify the bonus is still active, or update it if there is a change.

My HOT Take On New Casinos

I predict 2025 will mark a shift in the UK gambling scene, with players increasingly gravitating toward new online casinos over entrenched giants. These emerging platforms are offering compelling incentives.

Think £500 welcome packages with lower wagering requirements, unique game selections, and payout speeds that outpace the competition. As players prioritise innovation and agility over familiarity, the industry’s fresh faces may soon lead the pack.

How Do We Find New Online Casinos?

We have an extremely thorough process when it comes to finding new online casinos to bring to our readers. We’re always on the lookout for fresh sites – but before we add them to our toplists, we do some serious digging first. After all, we’re not here to bring you just any casino – we only bring you the best and most trusted new casinos in the UK.

All those little details like payments, customer support, game selections and more – even the things you didn’t think about – have all gone under the JohnSlots microscope to ensure their quality. So when you play at a new casino that you heard about from us, you’ll know it’s to be trusted. Here’s a look at just some of the criteria we test all new casinos against.

  • A safe, reliable and mobile-optimised platform: We’re living in the now, and that means we need a good new casino to offer an equally (if not more) high quality experience on mobile devices.
  • A great game selection: We’re not just looking for lots of games here, but lots of the top slot providers too. The more diverse the casino’s portfolio, the better the experience is going to be.
  • An efficient customer support team: As much as we’d like to hope you wouldn’t need it, a customer support team is key to a great casino experience. All new casinos need to offer fast and efficient ways to get in touch (preferably by live chat) so you can get all the help you need.
  • The best new casino bonuses and promotions on the market: We’re not looking for new casinos to offer the same old tricks. We want to see fresh offers and promotions with more competitive wagering requirements. We know a good offer when we see one, and that’s what we want for our readers.
  • Casino licences: JohnSlots only works with licensed online casinos so we can ensure the safety of our readers and fellow players. If a new casino hasn’t got their paperwork together yet, you won’t see them here on our site.

In addition to the basic criteria, we’re also always on the lookout for new casinos that stand out from the crowd. Maybe they have an engaging journey for you to follow or an eye-catching design. Perhaps their loyalty scheme goes above and beyond, or maybe they offer exclusive promotions to keep you coming back.

All of these things are taken into consideration when we promote a new casino, to ensure you have the best experience possible.

Are Our Casinos Licensed?

All of our UK casinos are licensed by the UK Gambling Commission (UKGC). UKGC was established to safeguard players and oversee internet casinos in the United Kingdom. An online casino’s licence to operate in this market may not be renewed or revoked if it violates the GC’s regulations. The licence number of a UK casino, which must be visible in their footer, may be verified using the GC’s register.

New Casino Bonuses

Why Should You Try a New Casino?

Even if you already have an online casino that you know and love, there’s never any harm in trying something new. You might find that you prefer the new casino over the old one, or it might just create a nice change. There are loads of benefits to be had from trying new casinos, including:

  • New casino welcome bonuses: New casinos know they’re up against fierce competition. So to reel in new players, they might offer a bigger and better welcome bonus than what’s already on the market. This gives you, the new player, the advantage since you can try something new with a big, fat welcome bonus.
  • Innovation: A new casino is often trying to fill a gap in the market – and that gap could be something you hadn’t even thought about. New casinos tend to be a little more on the adventurous side and may try innovations like gamification, VR games and other fun forms of entertainment.
  • Competition: When you leave an old casino to play at a new casino, it’s natural for the old casino to wonder where they went wrong. This in turn encourages healthy competition in the industry, inspiring older brands to evolve and innovate to keep up. We all win when this happens, which is why it’s great to try new casinos!
  • Better loyalty schemes: Similarly, the more casinos out there on the market, the more important it becomes to reward loyalty. Casinos are always going to want you to stay with them, so they’ll often improve their loyalty programme to make it more appealing to stay.
  • More choice in general: At the end of the day, the more options out there means you’re more likely to find the right online casino for you. You should never settle for anything less than a fun casino experience, and having the ability to try new online casinos allows you to find the perfect fit.

On the other end of the stick, the longer you’ve been playing at an online casino, the better they’re going to get to know you and what you like… and they better they’re going to reward you. It can definitely pay off to stick to one casino instead of bouncing around – but as we said, there’s never any harm in trying new casinos until you find your ultimate experience.

How to Choose a New Online Casino?

A new casino isn’t necessarily an inexperienced one. In fact, most of the time a new casino is the product of a team who got fed up with things going wrong with their old casino, so they started a new one to do it right.

With that said, there are a few things you should be looking out for when choosing a new online casino to make sure it’s the right experience for you. Let’s go through some of the basics.

  • New casino bonuses: One of the best parts of being a new player at a new UK casino is that you can claim a whole new bonus. This should be big, exciting and with fair terms and conditions to help you maximise your first deposit.
  • Good loyalty schemes: There’s not much point wasting your time and money to a new casino if they’re not going to reward you over time for your loyalty. Look for loyalty schemes where you can earn points that can be exchanged for free spins, extra funds or sometimes even gifts and prizes.
  • Exciting new touches: There’s also not much point in joining a new online casino if it doesn’t offer anything different from older casinos. Maybe they have a fun gamification experience or different games on offer – whatever it is, it needs to be worth your time.
  • A ‘try before you buy’ policy: We wouldn’t spend our money on something we didn’t know much about – and neither should you. Any good new online casino should give you the ability to navigate through their site and maybe even play some of their games without first making a deposit.

Are New Casinos Better Than Established Ones?

The one thing we’ve learned from our time in the gaming industry is that a more established casino isn’t always better. With that said, nor is a new online casino. There are pros and cons to playing at both new casinos and established casinos, which we’ll go through now.

Brand New Casinos

Pros
  • Better welcome bonus
  • More innovative
  • Exciting and fun new brands to explore
Cons
  • Less player reviews & possibly run by a smaller team
  • Might not have promotions nor VIP programme yet
  • Need to spend time learning about it all

Established Casinos

Pros
  • More trusted
  • Might have a great VIP programme & campaigns
  • More player reviews & casino is run professionally
Cons
  • Often less innovative & might need rebranding and new ideas
  • Might repeat the same promotions we’ve seen before
  • You know what to expect

What’s Next for New Casino Sites in 2025

New Rules for Gambling Promotions

Effective from December 19, 2025, the Gambling Commission will enforce new regulations to make promotional offers safer and simpler. The changes were announced by the UKGC on 26 March 2025 after a consultation following the 2023 White Paper. Analyzing the LCCP SR 5.1.1 we found the most important changes, which include:

  • Wagering Requirements: Capped at a maximum of 10 times the bonus amount. Currently, many UK operators have set wagering requirements of 40 or 50 times before the bonus cash from their welcome offers can be withdrawn. For example, a £100 welcome bonus that previously required a 40x wagering requirement, meaning the consumer had to wager £4,000 before withdrawing, will now be capped at £1,000.
  • Mixed Product Promotions: Banned; operators cannot offer bonuses that require customers to engage with multiple types of gambling products.

3.Licensees must not:

Apply wagering requirements, which requires a customer to play through bonus funds, over a maximum of 10 times. A wagering requirement is a where a customer is required to make wagers totalling a particular value for funds to become withdrawable.
Include more than one type of gambling product (betting, casino, bingo, and lottery) within an incentive.

Changes to Stake Limits for Online Slot Machines

The UK government has introduced stake limits for online slot machines: £5 per spin for players aged 25 and over, and £2 per spin for those aged 18 to 24. These limits are designed to curb excessive gambling and are expected to take effect in 2025.

Enhanced Financial Vulnerability Checks

Another new change that took effect this year was the requirement for operators to conduct financial vulnerability checks on customers who deposit over £150 within a 30-day period. This initiative aims to identify and mitigate potential gambling-related harms by assessing players’ financial stability. A six-month pilot phase started in March 2025 to refine these assessments through collaborations between credit agencies and gambling businesses.

FAQs

The Ins and Outs of New Casinos

Particularly when it comes to new online casinos, it’s natural to have plenty of new questions. And at JohnSlots, we’ve got you covered with all the answers.

Not all new online casinos are available for the UK, since this market now requires casinos to hold a separate licence. To make things easy and help you avoid disappointment, we actually list all the new casinos available in the UK in one handy page.

Our trusted team of casino experts at JohnSlots loves playing new online slots, and they’re always releasing new reviews of the best slot games. These are all listed in the slots section of our site, so you can peruse any and all that you’re interested in.

Most new online casinos will also categorise new games into their own section – but we recommend reading the reviews on our site first so you can go in with a better idea of what you like!

The answer to this question is not always yes… but if you play at a brand new online casino that’s listed at JohnSlots, you can always trust it. We only list new casinos that have passed our very strict tests, and the only casinos you’ll find on our site are those we’d play ourselves.

If you sign up as a new player at a brand new casino, you absolutely can get a new casino bonus – provided it’s on offer. Here are some of the new casino bonuses you could potentially take advantage of:

  • Casino bonus: A huge range of offers like reload bonuses, spins or more
  • No deposit bonus: Offers of spins or bonus funds that you can get by simply registering at a new casino
  • Free spins: Wager-free spins that could win you real-money prizes that you can keep for your own
  • Bonus spins: Similar to free spins but tied to wagering requirements that you must complete before withdrawing any wins. Often bonus spins will come in larger amounts

It’s really hard to say, because this can often depend on what’s happening in the market. Sometimes there’ll be a great demand for new casinos and sometimes not. For example, in 2019 we launched 10 brand new casinos at JohnSlots… but keep in mind, these were just the casinos deemed safe and trusted enough for us to work with.

Well spotted! We don’t review all new casinos at JohnSlots because quite frankly, some of them don’t deserve to be reviewed. We don’t expect you to read through pages and pages of reviews to get to the good stuff. We’ll only review new casinos that we have tried, tested and deemed worthy of your time and money.

Exactly, why not? There is one disadvantage to playing at new online casinos, and that’s the fact that you’d be missing out on loyalty bonuses that you would get if you stayed at the same casino. However, there are also plenty of benefits to playing at new casinos such as new welcome bonuses, innovation and more – so it comes down to what you prefer.

Often you can since new casinos will try to beat their competitors in their offerings. New casinos actually help keep the casino industry healthy, because they encourage both new and established casinos to think outside of the box and offer players new and more exciting bonuses.

Beginners are advised to set a budget, select games they understand, practice with demo versions, take advantage of available bonuses, familiarise themselves with payment options, and play responsibly.
