Wether it be different versions of Poker, different genres of slot games, including Irish slots, progressive jackpot slots and more!

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 to head on and create further winning ways. There are usually 2 different types of bonuses that you will find: Deposit Bonus 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. 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 being that the free spins can only be activated on certain slot games, for example Starburst. Starburst is one of the best 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 extremely 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, not to forget 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.

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%. 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 eligible to use a variety of payment methods. All casinos will have the generic Debit Card and Credit 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, 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. Meaning that you will have to use methods such as Credit Cards or Debit Cards: 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 online casinos, there’s 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, this is why it is important to take into consideration.

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

Telephone Support may seem like a rarity to some customers as a lot of casinos try to avoid it. However customers to love the efficiency of this method. Contacting a member of 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. 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 usually a timeframe in which you have to ring up.

Live Chat Support is a favourite. It is similar to email support only 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 this can really have a negative effect on their image.

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. Whether this be through previous features we have touched upon, including: Welcome Bonus, Games Selection, Safety and Payment Methods etc. The website layout 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 the licensing. If it is licensed under a respected and established online gambling commission, such as the UK, 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, this is under the data protection act rules.

The security at online casinos is excellent, they are created 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 customer’s 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 important 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 indicate 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 it is fixed. Meaning that there is a set-up which will determine whether or not you will win, instead of being completely random as it should be.

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 games. Especially if it is licensed under the United Kingdom Gambling Commission.
