If you’re anything like me, you don’t just want to dive into an online casino without doing a little digging first. With so many betting sites out there with flashy games and big bonuses, doing your research via UK casino reviews is a smart move to find the best of the best.
I draw on my decades of experience when researching and writing UK online casino reviews, and I know what to look for in a top-tier betting site. I don’t leave anything to chance – I sign up, deposit cash, and play for real. Everything I share in my reviews is based on first-hand experience.
Here, I explain why reading casino reviews is important and reveal my criteria for rating casinos. I also introduce you to three UK casinos that have passed my review checklist with flying colours and show you how to sign up today for brilliant bonuses that include free spins and cash.

Importance of reading UK casino reviews
Before I take a chance on a new online casino, I always read casino reviews in the UK. Legit, thorough, and professionally written casino reviews, like those published on Simon Says, give you the inside track on a betting site before handing over your details or hard-earned cash.
Many casinos don’t publish crucial information on their homepages, so reviews are a great middle ground. You can discover many of these details without committing to an online casino you know little about.
Case in point: you can’t always find essential payment information by visiting a casino’s homepage. Equally, there’s no way of truly knowing how many games are within a casino’s offering, as you can only see a snippet of the titles provided when you visit the casino without signing up.
I also look at trusted review sites as my first port of call when searching for a new and exciting online casino. What better way to find a quirky, exciting online casino than using a review site like Simon Says to discover legitimate, licensed online betting sites that might not have the big marketing budgets of the mainstays of the UK online gambling scene.
I do much of the research for you and present the key information in a digestible yet comprehensive review. You can then decide for yourself if the casino sounds like a good fit for your gaming preferences.
💬Simon Says: “I actually found one of my favourite casinos – All British Casino – via a casino review site. I had never heard of it before and decided to sign up after reading a brilliant review of the site’s quirky and unique British theme. I’m pleased I found it, as it’s one of the few UKGC licensed casinos that offer all players cashback.”
Online casino red flags you can’t afford to ignore
Before I run through my criteria for evaluating online casinos, I want to help you identify some glaring red flags you can’t ignore. The beauty of reading UK casino reviews is that you can identify these red flags before depositing and wasting your time and money.
So, here are some things to pay attention to and if any of these flags apply to a casino that you’re about to sign up for, I encourage you to look elsewhere:
🚩No UKGC license
The UK Gambling Commission (UKGC) is only one of many casino regulators worldwide, but because my reviews are focused on the UK market, I always check that the casino is licensed by this regulator in particular.
It’s common for offshore casinos to operate under a license issued in Malta or Curacao. While there’s nothing inherently wrong with this, you shouldn’t play at these sites, because you have no recourse if something goes wrong.
If you get stung while playing at a UKGC-licensed casino, you can at least take action and ask the Commission for support.
🚩Unrealistic bonuses
If an online casino offers a £10,000 bonus with no wagering requirements, you must stop and ask why. UK casino bonuses always come with wagering requirements (between 10x and 75x) and typically max out at £1,000.
Anything beyond this with zero wagering requirements is a red flag and potentially a scam. In the online casino world, if something seems too good to be true, it probably is.
🚩Negative player reviews
In addition to reading my UK online casino reviews, I encourage you to visit Trustpilot and Reddit to get a broader view of how an online casino performs. If the casino has an app, you can also find reviews on the App Store and Google Play Store, which offer handy insight.
You can ignore reviews by people who have lost at the casino and decided to complain about it – this is part and parcel of the world of online gambling. However, if a casino has dozens or hundreds of negative reviews about payment issues or poor customer service, it’s not something to ignore.
🚩Games from unknown studios
A lesser-known red flag to look out for is a casino that provides games exclusively from studios you’ve barely heard of. Legitimate, top-tier studios have their games independently audited by bodies like eCOGRA for fairness and transparency.
If a casino bypasses Pragmatic Play, NetEnt, Games Global, and other household names to provide games from random studios you’ve never heard of, there could be an issue. If the studio isn’t licensed and audited, you have no way of knowing that there’s a fair chance of winning.
🚩Unclear customer support options
When researching my UK casino reviews, I get really frustrated when betting sites hide their customer support options. What’s the point of this? Well, because they don’t want to help their players – this is a red flag in itself.
I appreciate transparency in this area. When I log in, I should be able to see clearly how I can contact the casino and which methods are offered. Something is probably amiss if I have to spend several minutes Googling how to contact the support team.
I also encourage you to contact the support team directly before playing for real. This will give you first-hand experience of how well they deal with your questions.
Criteria for evaluating UK online casinos
You might be wondering what I look for when reviewing an online casino. Well, there are some non-negotiables that every player should consider, while other things are helpful to know. So, here are my non-negotiables:
Licensing and regulation
The UKGC licenses and regulates betting platforms in England, Wales, Scotland, and Northern Ireland. While many other regulatory bodies worldwide (Malta, Curacao, etc.) exist, I’m only interested in UKGC-licensed sites.
Why? Because the UKGC is strict, reputable, and accountable. While I don’t necessarily agree with all their regulations, I respect and adhere to them. I also appreciate that the UKGC doesn’t accept shady actors and irresponsible operators.
If the UKGC licenses a casino, it’s a seal of approval and a sign that the operator takes player safety seriously. If the UKGC does not regulate a site, it won’t appear at Simon Says, regardless of how good it may seem from the outside looking in.
Game selection
I’ve encountered some offshore sites offering 10,000+ games, which is understandably appealing to bettors. However, most UKGC sites host between 1,000 and 3,000 casino games from 20+ providers.
This is the sweet spot as far as I’m concerned, offering enough variety without raising any red flags about the authenticity or quality of the game studios.
One of the first things I look at is which studios power the games. I prioritise games from top-tier providers like Pragmatic Play, NetEnt, Games Global, and Play’n GO. These studios are independently audited for transparency by eCOGRA and iTech Labs, giving you peace of mind that you have a fair chance of winning.
I expect to see 700+ slots, 50-odd table games, and 1,000 live options, including tables like blackjack, roulette, and baccarat, alongside live gameshows like Monopoly and Crazy Time. More on this later.
Bonuses and promotions
Everyone loves a freebie, and online casinos regularly run bonuses and giveaways. At UKGC casinos, these bonuses must be clearly defined with explicit conditions.
If a casino promotion seems too good to be true, it probably is. When trying to find the best bonuses at online casinos, I delve into the T&Cs to separate the wheat from the chaff.
Specifically, I look for reasonable wagering requirements, low deposit amounts, and bonuses that allow me to play various games.
I also look beyond the welcome bonus and consider which ongoing promotions, including reload bonuses and free spins, are served up to returning players.
Payment methods
I often use my PayPal account to make deposits at online casinos. Deposits are instant and fee-free, while withdrawals are usually in my wallet within minutes. This is also true of Neteller and Skrill payments at online casinos.
Though e-wallets are my preference, I appreciate that everyone is different, so I check that the casino supports debit card payments, bank transfers, and other convenient methods like Apple Pay and Paysafecard.
Crucially, I expect all deposits and withdrawals to be processed without fees. There’s no reason why the casino should charge you to transact.
Finally, I consider the time it takes for the casino to send you your winnings. Anything within one to three days is reasonable. If the casino takes five or more days to process a withdrawal, it’s a potential red flag.
Customer support
The best UK casino reviews examine customer support. It’s an important part of any online casino experience, and it’s something I always look for.
When things go wrong, like a delayed payout or a technical glitch, you want help fast. A good casino should offer 24/7 support via live chat, email, or phone. Reviews reveal how responsive and helpful the team is, not just what the site claims.
Do they answer quickly? Are they friendly and knowledgeable? That insight can make or break your decision. Solid support gives peace of mind, especially when real money is involved.

At a casino with a name like Mr Slot, I wasn’t surprised to find a huge selection of slot machine games. Overall, there are over 850 slots from the best studios – no unknown, shady developers here.
One of my favourite things about Mr Slot is the inclusion of the newest online casino games. As soon as you log into your account, you’re greeted by the “New Games” tab, enabling you to play top newly released slots like Lil’ Demon Gold Trio, Lucky Bass Mega Fire Blaze, and Joker’s Bonanza.

💬Simon Says: “I rate All British, Mr Slot, and Vegas Paradise as the three best casinos that I keep coming back to. I maintain my accounts and use them for slightly different reasons, which I explain below. These aren’t the only top-rated online casinos in the UK. Check out my list of UK casino reviews & guides for the scoop on some of my other favourite betting sites.”
In-depth UK casino reviews
When I fancy a spin of the reels or a game of blackjack, I don’t necessarily stick to one casino. Writing UK online casino reviews has shown me that some sites are better than others for certain things, be it bonuses, slots, or live casino action.
So, I wanted to explain my rationale for choosing All British, Mr Slot, and Vegas Paradise as three of the top places to play this year in depth. These in-depth reviews focus on three crucial areas of the online casino experience: bonuses, slot gameplay, and live casino magic.
All British Casino: best for bonuses
Though it has been online since 2013, I’m a relatively new convert to All British Casino. The unique and fun British theme drew me in, but as a regular player here, the bonuses keep me coming back.
Specifically, I love the cashback offer at All British, something I very rarely encounter at British online casinos. You’re eligible for 10% cashback on your losses, returned to your account weekly for even more chances to win.
Also, factor in the 100% deposit match bonus up to £100 for all new players, and it’s easy to see why All British is renowned for its excellent promotions. The 35x wagering here is lower than at many other sites in the UK, too.
As for ongoing promotions, All British focuses on cashback, but occasional free spins and reload bonuses are offered. You can keep an eye on the promotions tab on your casino dashboard for the latest promos here.
Finally, after setting yourself up with a 100% deposit bonus and 10% cashback, you can play over 1,000 casino games here, including Pragmatic Play slots and Evolution Gaming live dealer games.
You won’t find many better online casinos in the United Kingdom than All British.
💬Simon Says: “I want to share a little expert tip with you. If you can’t find any promotions listed on the All British site, drop the customer support team a message via live chat. They will point you in the right direction. But you can also request a bonus from the casino, and depending on your expenditure and play history, they might oblige. It’s worth a shot.”
Mr Slot Casino: best for slots
Given the name of this casino, it’s unsurprising that slot machines are the focus. All told, over 850 exciting slots are playable here, with Games Global, NetEnt, and Pragmatic Play all represented.
New games are added weekly, so you can play the hottest new releases as and when they drop. There’s also a decent line-up of jackpot slots at Mr Slot Casino, including top games like Shaman’s Dream Jackpot, Champions of Valhalla Jackpot, and Bell of Fortune.
If you’re hunting for classic, vintage slot machines, Mr Slot has you covered. Games like Bonanza, Rainbow Riches, and 88 Fortunes are among the most-played in the slot lobby. If you’re unsure which of Mr Slot’s games to play first, here are my favourite titles, with reasonable RTPs and high max wins:
| Slot Game | Developer | RTP | Max Win |
| White Wizard Deluxe | Eyecon | 95.50% | 1,500x |
| Big Bass Boxing Bonus Round | Pragmatic Play | 96.50% | 5,000x |
| Thunderstruck II | Games Global | 96.65% | 8,100x |
| Raging Rhino | WMS | 95.91% | 1,000x |
| Sweet Alchemy | Play’n GO | 96.50% | 3,000x |
When you sign up for Mr Slot via Simon Says today, you’re eligible for a 100% bonus up to £100, plus 40 free spins on selected slots. This is a great free spins welcome bonus, another tick in the box for Mr Slot when it comes to attracting slot machine players.
I should also say that, while Mr Slot focuses on the rows and reels, there’s also a decent offering of RNG table games and live casino titles, so there’s something for everyone here.
Vegas Paradise Casino: best for live casino & table games
Like most casual gamblers, I often daydream of a return to Las Vegas, where blackjack, roulette, and baccarat gameplay is unmatched. I’m also a big poker fan, so I relish my memories of playing Texas Hold’em and other games in Sin City.
Anyway, it’s not always possible for us Brits to hop on a transatlantic flight to play a couple of hands of blackjack. A good alternative is letting Vegas come to you, which is precisely why I highly recommend Vegas Paradise Casino.
Name aside, this casino has it all if you love RNG table games and live dealer titles. You’ll find 50+ RNG table games, including the excellent 3D European Roulette, Atlantic City Blackjack, and Casino Stud Poker.
But if you prefer your table games in the company of real-life dealers, Evolution Gaming, Playtech, and a few other studios power the live table games here. Evolution’s Blackjack Party is a personal favourite, but I also love Playtech’s Speed Roulette.
If live casino gameshows are your thing, Adventures Beyond Wonderland, Buffalo Blitz, and The Greatest Cards Show are all worth playing. Here’s a brief overview of the live casino games I highly recommend in the Vegas Paradise Casino lobby:
| Game | Studio | RTP |
| Buffalo Blitz Live | Playtech | 95.96% |
| Adventures Beyond Wonderland Live | Playtech | 96.70% |
| Spin A Win | Playtech | 97.22% |
| Mega Ball | Evolution Gaming | 95.40% |
| Red Door Roulette | Evolution Gaming | 97.30% |
Choosing the right UK online casino
Choosing the right online casino isn’t just about flashy logos or big bonuses; it’s about knowing what you’re getting into. That’s where a good review makes all the difference.
A well-written review gives you the whole picture: the games, the payout speed, the small print behind the bonuses, and how helpful the support team is. It’s like getting expert advice before you commit.
At Simon Says, I help you spot the red flags early, avoiding an unscrupulous online gambling experience.
Whether I’m after fast payouts, live dealer action, or an extensive slot selection, reviews point me in the right direction. I highly rate All British, Mr Slot, and Vegas Paradise, as they tick many of the most crucial boxes when researching and writing reviews.
So, before you make your first deposit or spin the reels, take a few minutes to read up. It’s the smartest and easiest way to find a casino that delivers what matters.
FAQs on UK casino reviews
Are UK casinos reliable?
At Simon Says, they sure are! I write all my reviews myself based on my first-hand experience playing at these sites. I sign up, deposit cash, and see how the site performs from a real user’s perspective. If I rate it, I write about it. If I don’t, I’ll tell you to avoid it and explain why.
What should I look for in casino reviews UK?
Depth, clarity, and proof that the reviewer has actually visited the site. Unfortunately, some reviewers skim generic details from other platforms and publish them as reviews. I don’t do that. I sign up, play, and experience the casino for myself. Then, I walk you through the crucial details in my reviews, giving you all the details you need before signing up.
How do I check that a recommended casino is safe to play at?
Good question. I only recommend online casinos licensed and regulated by the UK Gambling Commission. I don’t bring offshore casinos in far-flung jurisdictions to the table. After reading my reviews, feel free to double-check that the site is licensed. You can do this by visiting the UKGC website and searching the register.
What’s the biggest UK casino review red flag?
Be cautious when reading casino reviews that don’t include any negatives. No casino is perfect, right? A casino review must have pros and cons, and balance is key. If a review site pushes you too hard to join a casino, they’re probably being heavily incentivised to do so.
Where can I go for more information about reliable UK online casinos?
After reading my reviews on Simon Says, you might want to visit Trustpilot and Reddit to find out more about the casino in question. You may find some handy first-person insights to back up some of what I’ve said in my review. Alternatively, you can visit the casino and contact the customer support team to ask any specific questions.
