You will see the logos of these organisations displayed on the websites of reliable casinos, usually in the website footer. Please visit our responsible gambling page for in-depth help on this topic or visit the help organisations at the bottom of this page.

WHY GAMBLE ONLINE?

The word ‘online’ is synonymous with most things in everyday life nowadays, so it’s no secret that gambling can be enjoyed online much the same as you can offline a.k.a – in a land-based casino or gambling establishment. Many people prefer to gamble online because of the convenience it offers. You don’t need to travel further than your own home, or if partaking in mobile gaming – you can gamble any time and anywhere.

What’s more, gambling online is much cheaper than gambling offline, particularly if you have to travel. Gambling bonuses, casino promotions and loyalty rewards also come into this category is a major benefit that sets apart an online casino over a land casino. Often, when playing at an online casino, you have the choice of choosing to play with a variety of casino bonuses.

• Convenience: Play from your own living room or on the go on mobile or tablets. Gambling online is easier than going to a land-based establishment.
• Comfort: You can gamble online in comfort and confidence. Some people find land-based casinos daunting. Gambling online enables players to play in private, as well as offer plenty of time to brush up on skills and strategies to help them get more out of their game
• Bonuses: Gambling bonuses (including casino bonuses and sports betting offers) are plentiful online. Something which are they not and land-based casinos
• Better Games: Online, you can access over 5,000 different slot games from the best game studios. You can also play live casino games which are live-streamed to your device.
• Extensive Betting Options: Extra perks include live streaming, in-play betting and top of the line odds that you won't find on the high street.

BETTER CASINO BONUSES & BETTING OFFERS

The same goes for sports betting online. You can often take advantage of welcome sports betting bonuses, better odds and promotions, each of which add much more value to your play than what you’d find offline. It just isn’t commonplace to find such rewards at land casinos or bookmakers unless you’re a noted VIP player. The reasons are mainly due to overheads that a land establishment has to keep in order to keep the place running. It’s a costly business running a land casino, but running an online casino has much fewer overheads resulting in the ability to offer more promotions and perks.

There’s also a lot of choice and variety available at online gambling sites, often there’s far more games and online slots available than what you’d find at bricks and mortar casinos. Suffice to say, however, that gambling online doesn’t fully substitute the feeling and vibe you get when you go to a casino or bookmaker but it does offer a whole different modern experience. Traditionally, gambling offline is enjoyed socially which is why many online gamblers often travel to land-based casinos often when they have the time as well as gamble online when they don’t have the time to travel.

Our recommended top bingo sites are each licensed by the UK Gambling Commission and are completely safe to play at.

THE BEST GAMBLING SITES IN THE UK

With our extensive knowledge of what is and what isn’t a good gambling site, we make a top list of the best gambling sites every month. What makes the best gambling site is subjective according to your own tastes, but as long as you know they are legal, honest and fair, the rest of it comes down to the preferences you prefer as a player. This is why we review and rank so many different types of gambling sites; so that everyone who’s reading will find a perfect match. We assess gambling websites based upon game choice, deposit methods, payout times, safety, markets, bonuses and the quality of their customer service, among many other things.

Because we only list legit gambling sites here, the ultimate decision of “where to play next” rests upon your shoulders! Now that you don’t have to worry about ending up at a less than savoury site, we recommend that you take your time and do your research by reading our reviews and comparing different gambling sites to find the best match. Whilst doing this, keep in mind a couple of points:

HOW TO FIND THE BEST GAMBLING SITES?

We think that the first thing you need to do is ask yourself what it is you're looking for in an online gambling site. Do you want to play casino games? Slots or make online sports bets? What about games? If it’s the big progressive jackpots that you’re looking for, then a quick check on ay website is advisable, as game choice varies from casino to casino. This goes for any game – it’s best not to assume a casino will automatically have a game you have in mind because it might not. Whilst our casino reviews are in-depth, you can always check yourself before you start.

• Check For Games & Betting Options:  If the casino doesn’t have what you’re after but does have plenty of other new games and a fantastic casino bonus to welcome you, why not give it a go? Often you’ll find new and exciting games you hadn’t thought about trying before. And that’s the beauty of playing casino games online – there are always new and more entertaining games launched regularly.
• Check for Bonuses & Offers: Any new gambling site will welcome you will open arms and the lure of a really good welcome bonus. But, if you plan to stick around, then make sure there are a decent loyalty rewards program and regular promotions that you can make use of. Often it’s these offers and extra bonuses that can help you play for longer or help you engage in fun competitions that add an extra layer of fun when you’re playing your games

HOW DO WE RATE ONLINE GAMBLING SITES?

We play at every gambling site we list because that way, it will give us a good idea of how it really is when you get going. Aside from getting a good feel of a gambling site when we play there for real money, we also look for the following criteria when rating gambling sites. This is to help us weed out the sites which aren’t up to par:

LICENSING: WHAT LICENSE THE GAMBLE SITE HOLDS

You will only find the best gambling sites are the ones that protect you as a player – those which are licensed by the best gambling authorities. Look out for casinos and betting sites that are licensed by least the UK Gambling Commission and other leading gambling licenses such as the Malta Gaming Authority and the Alderney Gambling Commission.

GAME CHOICE: TOP GAMBLING SITES HAVE OVER 3,000 GAMES

Popular gambling sites offer a full range of casino games and/or betting options featuring premium providers. Our motto goes hand in hand with this: “quality over quantity” is important to keep in mind, because trust us -there are so many decent available to you, that there’s no need to be playing mediocre games that aren’t riveting nor fun or worse – have low RTP%.

BONUSES: THE GAMBLING SITES HAVE LOW WAGER / FAIR BONUSES 

Generous welcome bonuses and a clear and prominent rewards program are what makes sites stand out. Sometimes rewards programs can come in a format where gamification is used (the application of making activities more like interactive games to make them more interesting or enjoyable, in online gambling sense – to engage you to play more but reward you for it) but ensuring you get the best rewards from your first deposit, as well as clear directions on what you will get after that is important to take into account.

COMPATIBILITY: CAN YOU ACCESS ACROSS ALL DEVICES?

The best sites are the ones that are the easiest to access and play on. Those that are compatible with all devices; including mobiles, tablets and desktop browsers. The better the mobile website, the better too. Did you know that over 60% of online gamblers use mobiles to gamble online? Naturally, the best gambling sites are the ones that have put time money and effort into making sure their website is faultless on all devices, are lightning-fast loading and there no issues whatsoever.

PROFESSIONAL CUSTOMER SUPPORT: 24/7

It’s also important to be able to get help as and when you feel you need it, no matter your query. The best gambling websites offer fast and knowledgeable customer service, often with 24/7 opening hours. It’s standard for casinos to support 2 or more contact methods too, including live chat, email and sometimes a toll-free phone number to speak to a team member.

FAST CASHOUTS / PAYOUTS

Let’s face it, nobody loves waiting for their withdrawals to be processed, but it is a necessary evil due to licensing. A casino must perform checks. But that’s not to say that casinos should take an age to payout though. The best gambling sites are the ones that are fast paying casinos. We look out for those that issue payments within a day, offer instant and same-day withdrawals with the least fuss as possible.

NEW GAMBLING SITES 2021

The online gambling industry has grown exponentially in the UK over the past decade and with that have come many new operators launching new gambling sites regularly. This has created many casino sister sites which are casinos that are related to each other in some way; either operating on the same platform (and therefore having the same games and systems) or they’re owned by the same company. Casino sister sites are recommended because they’re often owned by iGaming companies that know what they’re doing as they run many other successful casino sites.

New gambling sites are often packed full of modern features and interactive casino promotions; such as casino slots leaderboards, slots tournaments or unique gamification features which if combined, offer a diverse gambling experience. We check out the newest gambling sites on the market and will list them in our new gambling sites section if they’re up to scratch.

Sometimes trying new gambling sites can feel like a gamble in itself because it’s the ‘unknown’ and out of your comfort zone, but there’s no issue in trying however many new sites out as you like; often playing at newer gambling websites will reward you with a new player welcome bonus and extra perks that you may not be receiving at your current online casino.

MOBILE SITES & GAMBLING APPS

Another important factor when choosing a gambling site is how you can access the games. How compatible is the site across different devices? The good news is, in this day and age there are plenty of mobile gambling sites and many new mobile gambling sites launching regularly. If you registered on your mobile, you will still be able to log in and play on via your desktop or tablet device with no bother. Casino games and betting software is designed to work flawlessly on mobile devices too. So, let’s face it – a site that isn’t wholly mobile-friendly isn’t going to last long these days. 

This is why so many online gambling companies spend much time and resource on their mobile offering. Whilst there are many gambling Apps, and some leading UK gambling sites also offer a downloadable app, it’s not necessary to find these as many sites are instant and easy to access via mobile browsers, without the need to download any bulky gambling Apps. If an operator doesn’t have a mobile website that works for you – we don’t recommend you waste your time on them. There are plenty of other top mobile gambling sites out there which are superb!

PAYMENT METHODS ACCEPTED AT GAMBLING SITES

There’s a large choice of banking options available to you, however, the choice does depend on the casino site and also the territory in which you are accessing it. Popular deposit methods for UK gambling sites include Debit Cards, many eWallets such as PayPal, Skrill and Neteller, Pay By Phone Bill systems like Boku, Klarna, Bank Wire transfer and PaySafe Card. UK customers please note, however, that you won’t be able to use any credit cards to fund your account as credit card gambling was outlawed in the UK in April 2020, but we’re confident that there are so many other banking methods available to you, that you won’t even notice!
