What we look for when choosing the best casinos online 2019:


It is not the case that all casinos offer you the same experience. Some casinos are more innovative than others. A lot of online casinos, the very best, can thrive in a number, if not all, of these following sectors. These are typically the most established ones, including William Hill, Grosvenor Casino, Ladbrokes Casino and more. It is all down to your own preference which features you value more than others. This can then lead you to make a justified decision as to which betting sites you prefer.

Game Selection

The game selection is massively important. There are so many different casino games out there that are brought to us by different casino software providers. Some of the best casino software providers include Microgaming, Netent, Playtech, NYX, Play N Go, Big Time Gaming, NextGen, Thunderkick, Evolution Gaming, Realtime Gaming, IGT, Novomatic, WMS and Betsoft. There are so many more providers in the industry, these are just some of the ones you will get used to seeing around as they are considered some of the most popular and the best.

The more games a casino can offer, the better it will be. It is vital to keep you entertained as a customer. If you are a frequent, experienced casino player, you will have experienced quite a lot of different casino games. You don’t want your fun to stop there as you run out of games to play. So, that is why, with a massive selection of games offered by particular casinos, you will struggle to get bored and you always have something new to experience.

Not everyone has the same taste in games, which is why it’s important to have something for everyone. Whether it is different versions of Poker, different genres of slot games, including Irish slots, progressive jackpot slots and more, the wider the variety, the better!

Welcome Bonuses

Inevitably, the first feature that is going to catch your eye when you want to sign up to a new casino, is the lucrative welcome bonus that is offered to you. These welcome bonuses are important to take into consideration as they are a great starting point for players. When used wisely, they can get you off to a good start and help to create further winning ways.

There are usually 2 different types of bonuses that you will find: Deposit Bonuses and Free Spins Bonus. A deposit bonus can typically be the most rewarding, as in some cases you can claim up to 400% on your first deposit. This is a great way to fund your betting account, giving you more to play with and improving your overall betting experience.

For players that particularly enjoy playing online slot games, the free spins bonuses may have a better appeal to you. Some generous casinos can offer hundreds of free spins! There can be rules to this, however.  A frequent one is that the free spins can only be activated on certain slot games, for example, Starburst. Starburst is one of the most popular online slot games and is what casinos tend to use in their marketing bonuses.

If you are very lucky, you may just find a casino that offers you both! Some casinos offer a deposit bonus and also free spins included in that bonus. That way you are getting the best of both worlds. This is ideal for players that like to play a range of game types at casinos.


It doesn’t just stop at the welcome bonus. Once you sign up to an online casino, there are new and existing customer offers available for you to activate. This is a great way to keep you interested and maximise your winnings and is simply a way of appreciating you as a customer. Some of the promotions you may come across are:

Free Spins No Deposit: These can be a rarity to find in the online gambling world, so if one does occur, it is not to be missed. This is a risk-free offer as you are getting free spins for slot games, without having to make any sort of deposit prior to it. This is a great way to experience particular slot games before you then place bets using your own funds. It typically comes in the form of a welcome offer for new customers but can be used as an existing customer offer.

Matched Deposit Bonus: A matched deposit bonus can work heavily in favour of the player. A matched deposit means that the casino will add extra bonus funds to your account to give you more money to play with, improving your overall user experience. For example, you may see a bonus of “100% Matched Deposit up to £100”. What this means is that if you deposit £100, they will grant you another £100, so you will have £200 to play with.

You can find more lucrative offers than this, for example a 400% deposit offer. Or you could find some that might only give you 50%. However, if you deposit more than the maximum limit, you will not be rewarded with more funds, only up to the limit.

Free Spins Bonus: This type of promotion will typically appeal to fans of slot games. Everyone loves free stuff. That is why some casinos can offer hundreds of free spins to welcome you to their site, trying to get you off to winning ways. For example, you may be given 200 Free Spins. There can be some wagering requirements in place before you can access this. Typically, there is an initial first deposit required in order to access the free spins. You may be asked to deposit £20 in order to claim the free spins.

Payment Methods

It is important for you as a customer to be able to have a variety of payment methods to choose from. So, when signing up to a new casino, ensure that you are able to use a variety of payment methods. All casinos will have the generic Debit Card payment options for you to successfully deposit and withdraw funds to/ from your betting account.

The typical payment methods that you will be able to use at the best online betting sites are PayPal, Neteller, Skrill, Zimpler, Bank Wire Transfer, EcoPayz, ECheck, Western Union, Bitcoin, Boku, Ukash, iDebit, ClickandBuy, Click2Pay, Webmoney. There are more that you may come across that are just as safe and secure!

Something that is important to consider is that not all payment methods can be successfully used to activate promotions. E-wallets are a perfect example of this. Particular e-wallets are not accepted by casinos to claim bonuses such as Neteller and Skrill. This means that if hoping to claim an offer, you will have to use methods such as Debit Cards like VISA, MasterCard, American Express, etc.

Customer Support

There’s no hiding the fact that players may experience a few technical issues or payment problems when playing at any casino. That is why at all online casinos, there are customer support options put into place to ensure the safety of you and your personal information. Not all casinos follow the same level of customer service which is why it is important to take this into consideration.

The generic options that you will find are Email Support, Telephone Support, Live Chat Support and FAQs. Email Support is a 24/7 support option that is offered by almost every casino. The great thing about email support is that you can attach documents to your email to provide more sufficient evidence. The only disadvantage with email is that replies don’t normally tend to be instant. You could be waiting 24 hours or more for a reply.

Telephone Support may seem like a rarity to some customers as a lot of casinos try to avoid it. However, customers generally love the efficiency of this method. Contacting a member of the team and speaking over the phone can be easier and faster at getting your point across rather than writing a long-winded email explaining your trouble and waiting for a response. Communicating in this way can result in a faster resolution. It would be better if more casinos offered this. Telephone support isn’t necessarily 24 hours, there is often a timeframe in which you have to ring up.

Live Chat Support is a favourite. It is similar to email support only with faster response times. Not all players like communicating over the phone and would prefer to type out their problem. That is why live chat is efficient. You can type out your issue and get a response within seconds. That way you don’t have to ring up and you can quickly resolve the issue. Live chat can also be a 24/7 Support method which makes it even better. Not all casinos offer this and if they don’t, this can have a negative effect on their overall rating.

User Experience

Ultimately, if you don’t enjoy your experience at a casino, you aren’t going to go back to them again. That is why first impressions are important and offering the best user experience is something that should be a priority to online casino sites. This is often through previous features we have touched upon, including Welcome Bonus, Games Selection, Safety and Payment Methods etc. The website layout also comes into play here too because players want something that’s easy to navigate and find their way around.


When you have your personal details and banking information shared with an online casino or any online betting site for that matter, it is important that you as a customer are aware that your data is kept safe and private. One way to realise this is through its licensing. If it is licensed under a respected and established online gambling commission, such as the UKGC, then it is within their laws that any customer details are kept safe and are not to be leaked to any unnecessary third parties. If any information was to be shared, then you will be made aware of this under the data protection act rules.

The security at regulated online casinos is generally excellent. They work with top of the range technology in order to ensure that they cannot be cracked. Therefore, no hacker can get into the site, where they could then access all of the customers’ details. This is often a worry for players. They struggle to understand online safety and worry that because everything is done through the internet, that maybe they might not be as safe as they would be if they just walked into a casino. Reading through the terms and conditions of a casino is a great way to get a full understanding of the safety measures that are in place. UK Gambling authorities also respect the importance of responsible gambling at UK online casinos and other betting sites for UK players. They want to make sure you enjoy your casino experience.


One major rule is that you should not sign up to any online casinos that are not licensed. The licensing of the casino is what indicates to you whether it is safe or not and also whether it is fair. Being a fair casino is something to consider because there will always be the conspiracy around online gambling that the machines are fixed. Some people believe that there is a set-up which will determine whether or not you will win, instead of being completely random as it should be. However, licensed casinos are tested regularly to make sure the RNG works completely fairly.

If a casino is licensed, then that is its proof that it is a fair casino that is not fixed in any way to obstruct you from winning. It is a fair set-up that gives you all the opportunities possible of winning. Therefore, you can play with freedom and excitement knowing that you won’t be cheated out of any casino sinnings. This is especially true if it is licensed under the United Kingdom Gambling Commission.

Mobile Gambling

With modern technology constantly being improved, there are always new ways to spice up the online gambling world with some new techniques and ways of betting. One way to do this was to offer players the use of mobile gaming, through the use of betting apps. This means that you can enjoy casino betting from the convenience of your smartphone or tablet device, including playing games such as Video Poker and even other online video live dealer games… (live roulette, video slots etc.). Since being adopted by casinos, with most of them now being mobile-friendly, it has been a huge success. Players now are encouraged to use them and some players have even gone completely mobile, due to its easy accessibility and the convenience of being able to bet anywhere at any time on the go.

Players would struggle to find an online casino that hasn’t adapted to the change and made their site mobile friendly. Players can still access all casino bonuses and promotions and all the online features that are available to the desktop versions. Some casinos will offer bonuses just for accessing their mobile app! For example, you could win extra spins or a free bet just for downloading their online casino app and playing through your mobile device. If you want a top online casino then this is something to take note of.


As you can tell, there is a lot to take into account when choosing the best online casino sites and it is not always just as simple as choosing the one that is at the top of your search engine. This guide should help you determine which online casino is right for you,  or even which type of casino you wish to play if you are unsure about the aspects you want to have included at a casino.

Different casinos compete in different areas of the market and stand out for different reasons. Some are better at offering bonuses; some are better for entertainment purposes and give you a huge selection of games to play; some are modern in comparison to others and include the latest modern technologies and some offer a wide variety of payment methods. It really does just depend on what you are after. Ensure that you are looking for a casino with a dedicated mobile site so that you can play on the go! We’ve made sure that you can use your iPhone or Android etc to play at any of the UK casinos we suggest.
