What We Look For In A Casino

The online casino business is all about options and entertainment. It is a service industry and they are they to provide a service for their customers and to give them the best experience they possibly can. As simple as this sounds, it is a very competitive industry and online casinos have to work hard to provide players with things that will set that site apart from all the others.

There are a number of different things that we at Betopin look for in a great casino. We want to see sites that offer as many options as possible. These options will come in the forms of :

  • A wide variety of different games for players to choose from (and we mean hundreds) — In order to run a successful online casino, operators must fill out their library with games that cater to every type of player. A versatile casino site should have a large number of slots, table games, and a few specialty games. Of course, having 500 video slots is undoubtedly better than having only 50 of them, but the number of games is meaningless if those games aren’t any good. In other words, quality is just as important as quantity, and it’s best if a casino has both.
  • Bonuses, promotions, and offers for players to take advantage of all the time — When conducting casino reviews, we pay the most attention to bonuses and promotions. This is because bonuses can make all the difference in choosing a casino site, as they give you a chance to start playing with extra money. However, reviewing the value of a given bonus is not so simple. While the size of the bonus is a good indicator as to how valuable the offer is, we still need to read between the lines and pay attention to various terms and conditions that are imposed on each offer. These conditions include things like wagering requirements, minimum deposit limits, maximum cashouts, and other things that you need to be aware of before claiming the bonus.
  • A number of different options for them to choose from for deposit and withdrawal methods — To even begin playing on a casino site, you will have to deposit some money into your newly created account. In order to do that, you will have to use one of the available payment methods offered by the casino. This is another element in which a casino site can show appreciation to its customers. A quality casino operator will offer as many different payment methods as possible, and they should include services like credit and debit cards, e-wallets, bank transfers, and cryptocurrencies, to name a few.
  • Payout rates that are fast and competitive across the industry — While we are on the subject of payments, having a wide variety of methods is not enough. An online casino should also allow for fast transaction times, especially when it comes to withdrawals. Also, we think highly of casinos that don’t impose any service fees on payment transactions and have optimal deposit and withdrawal fees.
  • A secure site where players will feel confident and comfortable sharing some of their most personal information — Unfortunately, the internet is full of scam casino sites that will trick you into leaving them your money. Moreover, while some sites might not have cruel intentions, they can lack proper security systems that can protect players. That’s why, before checking anything else, we make sure that a given casino site is regarded as safe and can keep your personal and monetary information out of harm’s way.
  • Casinos that are registered and regulated by major gaming commissions and associations — A proper gambling licence is the best indicator of the casino site’s legitimacy. Gambling licences are issued only to legitimate businesses that have been thoroughly checked and had all their paperwork in order. Some of the most highly rated casinos on our website have been issued licences from reputable gambling commissions like the UKGC (United Kingdom Gambling Commission) and the MGA (Malta Gaming Authority).
  • A site that is fun to be one with a great theme and functionality that is great on both desktop and mobile devices — Although some might consider this arbitrary, we think that website design is another major thing that affects your online gambling experience. We are always in praise of casinos that have a unique theme and a site that provides easy navigation. Also, we always check how the website works on mobile and whether the operator offers a mobile app for Android and iOS.

There is a lot that goes into an online casino and Betopin has identified some of the top sites on the internet. They meet all of these criteria and score highly on them as well. A few of the top sites that we have identified and reviewed include:

These are a few of the many, but they are on the top of our lists of great sites. Each site you can see listed here is considered 100% safe and has proper licensing. Moreover, they are full of action-packed games, rewarding bonuses, reliable and fast payment methods, and other things that make them worthwhile.

Here is some in-depth information on how we go about review online casinos and the things they have to have in order for us to consider them one of the best.

Most Popular Casino Games

The games are the most important part. This is the reason why players are there in the first place and online casinos have to provide a great array as well as great options on the most popular. The best casinos offer hundreds of different games that are created and supported by the top gaming software companies in the industry.


Slots are an important part of a sites gaming library. They need to have slots games of all different themes and with all different types of bet lines. Slots are a popular choice among gamers because they are a game that they can play easily and many new gamers will start out with these types of games in order to get the hang of playing on these sites. They are also a fun way to gamble while still being able to socialize with other gamers from around the world.

Video slots are also fun because they can be themed. Some software developers have acquired licences to include characters, symbols, and soundbites from popular movies and TV shows. Also, many players enjoy playing video slots because they are the most rewarding games of all. Progressive video slots can have jackpots of over several million pounds, and it takes only one lucky spin to win.


After video slots, blackjack is the most popular casino game in the online gambling world. There are several different types of blackjack and, because of its popularity, several top software developers have made their version of the game. It is safe to say that every reputable online casino has a few quality blackjack games in their collection. The game is also commonly played in a live dealer form.


Poker is a staple of any brick and mortar casino and it is no different for an online one. People love to play poker because of all the different types there are and because it gives them the feeling of being at a real table. Poker is one of the most popular around the world and there is a lot of variety and spin that a site can put on this game.

While most casinos have only casino poker — a poker game played against a virtual dealer, some online operators have dedicated poker rooms where players can compete against each other through cash games and tournaments.

Video Poker

Video poker differs from other poker games because it features no opponents and the goal of the game is to create the best possible combination of cards, with each more powerful combination resulting in a higher payout. There are several different types of video poker games, the most notable being Jacks or Better, Deuces Wild, and Joker Poker.


Roulette has a number of varieties. It is a simple game and it is easy to place bets on. It is also popular because it is another one of those games that give people that real casino feeling right in the comfort of their homes. The top sites are going to offer different varieties of this game from standard rooms to those located in a site’s ‘Live Casino’ section.

The most popular online variations of roulette include American, European, and French roulette. However, several novelty roulette forms have appeared in an online form, such as double-ball and mini roulette.


Like Roulette and Poker, this is a game that people will find inside any casino they visit. This is one of the reasons why reputable online casinos must offer an option for players to play this game. The purpose of an online casino is to provide that gambling experience to players right in their homes, or wherever they are playing. These types of games are popular because these sites make it so that people don’t have to travel to the casino to play.

Baccarat is often one of the first games beginner players test their luck on. This is because baccarat rules are really simple to understand, and the game is almost entirely luck-based, meaning that you won’t have to worry about memorizing any sort of complicated strategies.


Craps is one of those casino games that are best experienced in a land-based casino. Nevertheless, many online casinos feature craps on their list of available games, as it is fun and potentially very rewarding.

Let’s Go Over What We Look For In Top Casinos

Let’s talk about specifics. So far, we have given a general idea about what to look for, but let’s talk about specific things that these sites have to do in order to even make it on our list of great sites.

Bonuses and Promotions

Any casino worth their weight is going to offer plenty of bonuses and promotions. Honestly, who doesn’t want to get free funds or spins to play with on an online casino? Some sites will do this better than others, but there are particular things that players will want to look for when it comes to distinguishing mediocre sites from great ones.

They are going to need to offer players a welcome bonus after they sign up and make their first deposit. Some sites will give bonus funds to players without them having to make a deposit. Welcome bonuses are a way to draw in new players and they give the players a chance to feel out the site and see what they are all about.

Those Wednesday night or Thursday afternoon promotions are important. These promotions will keep people coming back and it gives them something to look forward to when it comes to their gaming plans. VIP or Loyalty Programs are necessary too. The best sites know how to reward their loyal players for all of their time and money that they have spent.

While casino bonuses are worth using no matter how you flip it, some bonuses come with very restrictive terms and conditions. You will have to meet these terms in order to get a chance at withdrawing your winnings from the bonus, and that can sometimes look impossible. That’s why we always carefully read the terms and conditions and leave positive notes to websites that have reasonable wagering requirements and other limitations.

Live Game

Live games give players the feeling of really sitting in a casino and interacting with a dealer and other players. Live poker, roulette, and baccarat are some of the most popular. These types of games are found at all of the major sites. They are going to work hard to make sure that their customers can access these games from any device, any time of day or night.

Live dealer games work flawlessly on all new devices. However, you will still need a stable internet connection if you want to run these games without interruption and while enjoying HD stream quality. Several software developers have established themselves as leaders in powering live casino games. We are always happy to see a casino that has titles from Evolution Gaming, as they are by far the best and most popular live games right now. Good alternatives to Evolution Gaming’s live dealer games are NetEnt Live, Lucky Streak, Playtech, and Ezugi.

Quality of Games

These sites are for fun and entertainment. The top sites make sure to take the time to plan out their theme and make their site appealing to the eye. They are going to make sure that they are supplying their players with games from all of the top gaming software providers in the world. A lot of games is not going to make up for poor quality. The top sites that we list on Betopin are going to have games of top quality.

To ensure that these games are outstanding, we look at who has made them. If we see a lot of titles from software providers such as NextGen and Microgaming, that’s usually a good sign. However, we also spend a significant amount of time playing various games and reading what other people had to say about them.

Mobile & App

Mobile functionality is important in everything that we do. Google is even ranking sites in its search engine results higher when they have a mobile site that is well-reviewed. Most people are doing everything on mobile devices. Online casino gaming is no different. The top online casinos are going to have sites or apps that are going to have amazing functionality on any and all mobile devices.

Playing games on mobile is really advantageous. You can log into your online casino account at any given time and play from a location that is most suitable to you. Luckily, most modern games are made to be mobile-compatible, meaning you will find that the number of available mobile games on a given casino site is almost parallel to the number of games you can play on desktop.

Moreover, certain casino operators encourage their customers to use their mobile sites and apps by offering special mobile bonuses and promotions.

Deposits & Withdrawals

All sites are going to offer players the ability to deposit and withdrawal with credit and debit cards. The best sites are going to give the most options that they can in order to appeal to more players. In addition to the credit and debit card options, these sites will offer the option for e-wallet methods like Skrill, Neteller, and Trustly. Alternatively, players can use direct bank transfers for extra security and higher deposit and withdrawal limits. Some online casinos have even started accepting cryptocurrency payments as of late.

One of the most important things about the best sites is that they have a fast withdrawal time without any fees for it. The faster that a person can win money and withdraw it, the better the site. No one wants to have to wait 2 weeks for the money that they have won. Of course, this will also depend on the payment method you end up selecting, but sometimes casinos have unnecessarily long withdrawal pending periods, which can be frustrating.

Customer Support

Every player should feel welcome when they join an online casino. If any issues arise, a player should always be able to count on professional and responsive customer support. We usually contact customer support when conducting reviews in order to inform ourselves about the casino and to be able to rate the customer support itself.

A quality casino site should give players multiple modes of contact. The best way to contact one of the support agents would be through a 24/7 live chat. Alternatively, you should be able to use email and phone (ideally with a toll-free number for UK players).

How to Create an Online Casino Account in the UK and Start Playing — Step-by-Step Guide for Beginners

We understand that some of you who are reading this article are not that familiar with online casinos. Don’t worry, as we will walk you through the entire process of creating a casino account and starting to play.

  1. Choose a quality casino site — This first step is the most important one. In order to have a great online casino experience, you will have to choose a quality casino site. Browse through some of our reviews in which we evaluate these sites and break down their contents. Base your choice on the games that you want to play, bonuses you want to use, and the payment methods that are most convenient to you.
  2. Register / Sign up — After you’ve settled on a single casino site, you should go ahead and create an account there. There will usually be a Register, Join, or Sign Up button on the homepage. By clicking on it, you will be directed to a page containing a registration form. Fill out all the necessary fields in the form with details such as your full name, date of birth, zip code, address, and similar. This is also where you will set up your login details (username/email and password).
  3. Deposit — The next step involves the deposit process, which is also quite simple and takes just a few clicks. First, you should navigate to the cashier page, although most casinos have a Deposit shortcut button visible at all times. Select one of the available deposit methods (e.g. Visa, MasterCard, Skrill, Bitcoin, and similar) and input the amount you wish to deposit. Most deposits take just a few seconds to be completed but allow a casino up to a few minutes to process the payment. Refresh your account page, and your balance should be visible.
  4. Claim the welcome bonus — The process of claiming the welcome offer might be different on different casino sites. In most cases, the bonus will be automatically unlocked when you complete your initial deposit. However, sometimes you will need to claim the bonus manually, as certain casinos leave you the option to play with your own money first. Make sure to check every field while completing a registration form and making a deposit, as some casinos might put a checkbox here through which you will confirm that you want to offer. Also, pay attention to bonus codes (if necessary) and input them in the appropriate fields.
  5. Start playing — Once the deposit goes through and your welcome bonus is ready to be used, you can start browsing the casino site’s library of games. Click on the game of your choosing, wait for it to load, and start playing. Have fun!


It is all about options and entertainment. The top sites are going to spend a lot of time making sure that they are giving their players the most high-quality options that they can. They are going to make sure that they are focused on making their customers happy because, without their customers, there is no site.

They know the importance of their customers and they work to make sure that they are happy, earning money, and having a great time.

We hope that this article helped you learn a lot about online casinos in the UK. Make sure to read our reviews and learn more about each UK casino and its offers. Good luck!


How to choose the best paying online casinos?

There are three things to look out for when looking for a new online casino to join.  You must remember that the major games are all industry standards.  Payout rates are generally above 90% for the major online casinos and you’d be a fool to join a casino and lodge your hard-earned money with one that has not been properly vetted, regulated, and is well established.  Below we go through the three main things to look for to compare casinos:

Who are they regulated by?

Never deal with an online casino that is not regulated, you’ll be asking for trouble. The games may play fine, but you’ll only come into problems if you have a big win and try to withdraw funds.  The main governing bodies worldwide including eCogra, TRUSTe, GamCare, Gibraltar Gambling Commissioner.

How well established are they?

It may be tempting to go with a new casino and take advantage of a monster welcome offer.  It’s relatively easy to set up an online casino these days.  All you do is pick a name, some branding they rent some software and platform.  The problem here is that whilst your welcome offer may seem good there will be lots of terms and conditions attached and the brand operator may opt to pay out a lesser amount to compensate for the start-up costs.  Always stick to the established casino brands as they offer a tried and tested payout structure, good casino new player welcome offers and continued promotions once your account is open.

How financially stable is the company behind the online casino?

You should beware that just because you are dealing with a big brad it doesn’t mean that your funds are being held by them.  They may be held by the underlying casino platform provider so make sure you check them out too.  Many well-established brands such as William Hill Casino have done their due diligence before entering into such an agreement.  A big brand may be more included to look after its customers if there is a problem with the provider too.  it’s generally best to go with brands that are listed on a stock exchange like 888, William Hill and Paddy Power.  The share price chart will show you at a glance if they are doing well or headed for trouble.
