How Do We Rate Casinos?

Written by
At Casino.online, we are committed to delivering honest, data-driven, and player-backed casino reviews. Our three-step process ensures accuracy and fairness by combining in-depth analysis, industry comparisons, and real player insights.
Casino expert reviews backed by data-driven analysis
Our algorithm analyses 500+ data points, evaluating key factors like game fairness, bonus conditions, bank options & security. Based on these insights, our experts personally test each casino to ensure accurate, unbiased, and experience-backed reviews.
Aggregated casino score based on the web's most trusted sites
We provide an aggregate rating made up of rankings from other trusted review sites like 'Casino.guru' and 'AskGamblers'. This way, you get a full picture of how casinos are rated elsewhere and all the tools to make informed decisions when selecting a casino.
User reviews from real casino players' feedback
Our team pays attention to real users' feedback, by reading player reviews, forums, and complaints. By analyzing trends in player satisfaction, we highlight what users love and warn about potential red flags.

We only review safe and legitimate casinos
While not all our reviews are positive, we only list casinos that we deem to be safe and secure. It goes without saying that all our listed casinos have a valid UK Gambling Commission licence and a track record of timely, reliable payouts.
In one sense we are reasonably lucky that we have a highly regulated marketplace in which some of the worst excesses practised by online casinos in unregulated markets are not allowed and responsible gambling is taken extremely seriously. So the worst casinos have been shut down or had licenses revoked. Well-known brands need to be consumer-friendly and be vigilant on responsible gambling so there is a degree of brand protection going too.
You can learn more about some of the people who work tirelessly behind the scenes to bring you the best results on the 'about us' page.
What is important to consider in an online casino
Casino welcome bonus comparison
One of the key things most of us want to know about a casino before signing up is the type of welcome bonus offers they have available. With our easy to use casino filtering system and our great Telegram Channel, you can search for the perfect welcome offer.
Whether it’s low wagering requirements, high % match or simply a large cash amount that you are after you’ll be able to sort and search our casinos on any of these elements. Our comparison will provide a superior, well-structured list of all available Free Spins No Deposit, Casino Cashback Offers and Casino Promo Codes.

“We will be adding new online casinos on a regular basis so it’s always worth coming back to us to look for new operators when you fancy a change from your existing casino provider. We update all our bonus information continually in our database so we only ever show the most up to date operator info, meaning you can make your choice based on up to date numbers that you know to be correct.”
Existing player promotions and loyalty schemes
Ongoing, daily, weekly or monthly promotions are an important part of the mix for player experience at an online casino. There are some casinos that have loyalty down to a fine art and others that don’t.
Loyalty can be split into two different areas, firstly there are the more generic onsite promotions that casinos run, they are available to everybody and can range from prize draws for big prizes to cashback on specific games – these tend to be a nice cherry on top of the casino promo experience – you can dip in and out of these promos as you see fit going for the ones you like and leaving the ones you don’t. The second type of loyalty is a more bespoke type tailored specifically to your favourite games – this will be run by a loyalty team and will arrive via text or email made just for you. This be double comp points offers, deposit matches, cashbacks or even free cash. It’s worth watching out for these as they tend to be more generous and better suited to your style of play.
We keep our ears close to the ground on loyalty, listening to feedback from players and playing ourselves to make sure we’re up to speed with which casinos are getting in right and which are not.
Casino design and usability
With so many casinos offering the same games and similar promos, design and usability can be an important way to make a casino stand out from the crowd. On very good example for excellent design and usability is the BC Game Casino.
So it’s strange that so many casinos are still so poorly designed. Some of the smaller sites you’ll find may not have too much choice other than to follow the template of a software provider, however, the bigger players normally will have complete control over everything from games interface, to live chat to the cashier.
Admittedly the standard of design and usability has been raised in recent times mainly by a glut of new Scandinavian casinos that have taken the time and effort to think about design. This in turn has risen the standard and we are seeing improvements across the industry.
This is an area we focus on in our reviews, but it is somewhat subjective so you’ll be the best judge of what you like and what you don’t like.
Casino game selection
Game selection is another extremely important aspect of reviewing a casino – many players have software providers that they see as essential to an enjoyable gambling experience. Many people love to play online roulette for example. For this reason, we allow you to filter the casinos on this site by game software – so if Starburst is an absolute must for you, simply filter casinos on NetEnt and you’ll see all the casinos that will carry that game.
Because there is so much choice now and so many different game providers some players look for a quality curation of games from their casino. It’s no good having 2000 games on-site if most of them are old, unplayable and not up to today’s standards. Some casinos are doing a good job of this – getting lots of game providers on board but only publishing the real quality. Also, trending games like Crash Gambling is an important feature, that Casino.online will cover frequently.
Mobile casino product
Quality mobile casino product is essential to a modern online casinos survival. All casinos now have a mobile product and many are thinking in a ‘mobile-first’ was as over 50% of casino play and revenue now comes from mobile casino rather than desktop/laptop.
A decent mobile product should do everything a desktop product does without trying to copy it exactly. Things must be done slightly differently on mobile, it’s a smaller space, so design work needs to take this into account and make games and interface features just as usable on mobile. Most casinos are getting there with this and it’s rare to see very poor mobile sites these days, but some casinos certainly do a better job than others.
Progressive Jackpots
Right from the start, online casinos have grabbed headlines for the huge progressive jackpots on offer. At the start of the industry, people found it hard to believe that such giant jackpots were possible to win online. At one of the casino operator offices, a casino customer refused to believe that he had won £8.5million until the cheque had cleared in his bank account.
These days with a few more years behind the industry and casinos much more common progressive jackpots are much more commonplace and all the major software providers include at least one progressive jackpot of a decent size as part of their package and casinos consider jackpots an essential part of their gaming mix.
Progressive slots are not typically suited for daily play due to their lower payout ratios, usually between 90-95%, compared to the standard 96% or higher for non-progressive slots. With top games like Playtech’s Jackpot Giant, Microgaming’s Mega Moolah, and NetEnt’s Mega Fortune readily accessible at UK casinos, players have many options for chasing those substantial jackpots.
Live chat and customer support
Live chat and customer support are an essential part of a good casino. Customer support is another area that casinos have the chance to stand out from the crowd as often it’s something that is unique to them. Well trained staff who know what they are talking about and can genuinely help you with a problem are a godsend and can really improve your gaming experience.
Customer service is something we cover in detail within our review section where we look at answer speeds, general knowledge and helpfulness. A casino with their customer service team in order is generally a sign of a well-run operation so pay particular attention to this area when selecting your casino.
Casino Payout Ratios & RTPs
Not all Casinos publish their payout rates, however, all UK licensed casinos are required to be audited in order to keep their license. If the payout ratio is published we’ll list it here on-site as part of our review of the casino.
There are other ways of knowing what the expected payout will be on particular games at your selected casino. Some game developers will include RTP in their game pay tables and frequently casino sites publish RTPs for particular games on their site. In many ways, it's most important to know the payout for the games you are playing rather than an overall payout for the casino as your expectations as a player will be very different depending on whether you like progressive jackpot slots or online blackjack.
Live casino and live dealer
Live casino is an essential part of the online casino product mix these days and no self-respecting online casino with any ambition is without a live product. Evolution software are widely regarded as the industry leaders in Live Casino and you’ll see that many of the casinos listed on this site outsource their live product to Evolution.
Regardless of the product provider, what we look for in Live casinos is well-trained dealers, busy tables and a great atmosphere where you are made to feel welcome at the tables. Live casino can be the most fun element of playing casino online – interaction with real people and banter at the tables all from the comfort of your own home.
There’s an ever-increasing choice of games at Live casinos with tables to suit every level of player. Along with old favourites like roulette, you’ll also find baccarat, poker, VIP tables and game-show-style games like Evolution’s Dream Catcher, you can also find VR Casinos gameplay.
Payment options and withdrawal times
Payment options are clearly a vital factor in the online casino mix – a casino that gives players the options they need and offer quick, no-fuss withdrawals is generally a casino that has got its house in order and is worth considering.
Quality casinos will choose payment solutions that offer both security and convenience – they will clearly list their payment methods, along with the attributes and withdrawal times of each, making it easy for you to decide.
A good range of methods from the likes of Boku (pay by mobile), standards like VISA debit and eWallets like Neteller, PayPal and Skrill is what you are after – this way you know you have a choice and that the casino is doing its best to cater for its player’s needs.
When it comes to choosing your payment method, withdrawal times are obviously a key consideration, but you should also consider security. While no quality online casino would partner with a disreputable payment method, you should choose a payment brand you know and feel comfortable with.
Some casinos have adopted cryptocurrencies as a payment method. As a result, such crypto casinos have gained popularity in the last few years. A decent example for a good casino using crypto coins is Bets.io, which we already reviewed.
Responsible gambling advocacy
It is now a given that UK Casinos must comply with the Gambling Commission’s rules on responsible gambling. There are all kinds of rules in place around marketing, in-play and customer service that online casinos must follow – this has made the online gambling environment, safer for players and stopped unscrupulous operators taking advantage of players.
Responsible gambling starts before customers even sign up to casinos – with rules around advertising. Advertising cannot appeal to under-18s or use anyone in the advert who looks under 25. Significant terms must always be displayed when showing an offer online and adverts must be placed only in socially responsible places that adults visit.
Once a player has signed up to a casino and started playing easy access to account information such as gambling history, deposit info and the ability to set deposits with limits or there are casinos with no limit, but must all be in place for UK-based operators. Casinos must also promote the site begambleaware.org – this gives players detailed information about recognising gambling problems, and staying in control and offers help and support to those players who feel that gambling has stopped being fun anymore.
We would only consider casinos that comply with all of the above and have a decent record of responsible gambling – a casino should look out for their players' well-being as well as provide a quality casino product.
Casino terms and conditions
Terms and Conditions are certainly not the most exciting element of choosing your online casino, however, it is very important to get an understanding of not only the casinos main Ts&Cs but also the terms that are attached to the bonuses they offer.
We provide key terms to each bonus wherever it is mentioned on site – this will give you an idea of the most important terms for each bonus – things like wagering requirements, expiry, game restrictions etc – however, we would recommend giving the full Ts&Cs a look over before depositing with any online casino – this way you know where you stand and you are unlikely to be met with any surprises later down the line.
Our meticulous casino review and rating process ensure we recommend only the best casinos to our readers.

FAQs About Online Casinos
What are the best online casinos?
Pretty much everyone asks this question when they first start gambling - what are the best online casino sites in the UK? Unfortunately, there is no one solid answer that we can give you. There isn't one casino we can point to and say yep, that's the one you should go to, for sure! After all, you can spend all day recommending the best sushi restaurant to someone, and they'll still think you're a liar if they don't like fish.
We've made it a point to showcase the top online casinos, review them and evaluate their strengths and weaknesses, but we can't tell you which one you're going to enjoy most. Only you can answer that. If you're looking for a UK online casino site with a strong deposit bonus, you might end up with a different choice than if you're looking for a great live dealer experience. Not even the best UK casino sites are masters of all.
That's why it's super important to read our reviews carefully and use them as a base to determine where to sign up. If you're interested in decent online casino bonuses (for example a 100% welcome bonus), your prime destination should be the bonus section of our review. And if you're judging them based on what online casino games they offer, you could take a look at our pages for the respective games, which will only list UK online casinos that contain those games.
Which online casinos are legitimate?
All casinos listed on this website are legitimate in that they are licensed by the Gambling Commission and have a track record of fairness either through the owners or the casino brand itself. This, of course, does not mean that we necessarily like all the casinos listed or give them a positive review – a casino can be 100% legitimate business and still not be very good.
There is so much more to choosing a casino than simply knowing that it’s legitimate; customer service, game selection, payout times and many more factors contribute to how we rate casinos. We would recommend reading both our reviews and the comments of our readers before choosing a legitimate casino that suits you best.
If you have any specific questions about any of our listed casinos and their legitimacy, please don’t hesitate to get in touch and we’ll do our best to help.
Which online casinos can I trust?
First-hand experience is really the only way you can truly 100% have confidence in a particular casino – getting to know customer service, withdrawal times and the games on offer for yourself will truly determine the level of trust you personally place at a particular online casino.
However, there are of course ways to get a good sense of which casinos you can trust via this site and you don’t have to believe solely our opinion either as we collate ratings from lots of casino sites and also invite reader to give their ratings also.
Read our reviews, check the casino's credentials within those reviews, check out the ratings that we collate from around the web, check readers' opinions of the casino, and armed with these three differing sources of info you should be able to choose which casinos are most trustworthy and therefore deserving of your custom.
Can online casinos be rigged?
Perhaps in unregulated territories or casinos that cater for customers in countries in which playing online casinos is illegal, however, in a market that is as highly regulated as the UK (probably the most regulated market in the world) it is not possible for an online casino to be rigged. Everything from overall casino payouts, to licensed games to reality player checks needs to be approved by the UK gambling commission for a casino to continue to hold its licence. There are heavy fines and closures for any operator that does not follow regulations so it's simply not work for a UK licensed casino to be anything other than 100% above board.
Can online casinos ban you for winning?
The Casino.online team have extensive knowledge of working with online casino operators and we have never experienced any of them closing player casino accounts for winning. This sort of practice does happen in Sportsbetting where accounts are profiled and limited when winning on particular sports, but not at Casinos.
Ultimately the Casino is operating at an edge (check the payout rate of your online casino before you start playing) and the owners of these casinos know this. Winning is the main reason players will play at a casino so it’s very important winners are looked after and celebrated in the same way all customers are.
Can you beat online casinos?
If by the term ‘beat’ we mean ‘win’ at an online casino, then yes, you can absolutely win at a casino – huge progressive jackpots are won every day, and players walk away with small wins on the blackjack or roulette tables or someone hits the top win on a slot machine and those that are smart walk away with their winnings!
Playing games that have the smallest house edge will give you the best chance of winning in the long run, but if you’re looking for a big win then a high volatility slot with big payouts could be the game for you – the wins will be less frequent, and you may find your bankroll depleted but you never know a big win may come your way.
