A Selection of the Best Online Casinos

Of the many online casinos, deciding which to join isn’t always as simple as it might seem! New players create online casino accounts frequently, but a small portion end up disappointed with their selection, or even worse, finding their way into the grasp of a rogue online casino operator. This can do more damage than just preventing the enjoyment of playing casino games. More importantly it can lead to a loss of deposits.

Unfortunately, not every online casino is a legitimate, trustworthy operator. When you factor in the long-standing historical precedent of rogues in gambling - from backstreet hustlers to Mafia-run casino resorts - alongside the need to trust a casino with your money and personal information, there are more reasons than usual to have a serious think about any decision you make.

However, there are also hundreds of thousands of online gamblers, happy with their chosen online casinos as a consequence of the high standard of customer service, game selection and the overall gambling experience on offer.

So what factors should you know about any online casino before doing business with them, and why it is so critical to do your homework before you commit to any one particular operator?

The best way to develop a balanced and complete overview of all the different online casinos is to read casino reviews that include past player experiences. As with any significant commitment, carrying out due diligence is worth the time and effort in order to reap the reward of choosing a reliable and trustworthy online casino.

Learn from Past Experiences of Other Players

Previous experience can never guarantee future results. However, it is almost certainly the best tool that exists in terms of evaluating whether or not an online casino is lawful, genuine and safe to join. If other players have already registered and joined before you and have had a positive online gambling experience, you can at least be assured that the casino in question is a legitimate operator and offers a good service. It is then in your hands to research and compare the details of different licensed and regulated online casinos in order to find the right one for you.

Do not be deceived by elaborate marketing schemes and flashy websites – the main thing to take notice of is the customer experience. Even the best and most attractive looking casino website could be hiding aggressive and roguish terms or fraudulent business practices designed to deceive and cost you money. Do your research before you decide to deposit and entrust them with your funds.

Licensing & Regulation is Essential to Check

This is an area, which the majority of casino players rarely think about, yet it remains extremely important when looking to join an online casino. In order to transact business in a fully transparent and compliant way, casinos by law have to be licensed by a regulatory body. This enables them to operate casino gambling services, whilst at the same time ensuring consumers have a right of recourse in the circumstance of unfair or illicit treatment.

Any casino you do business with should be licensed by an external authority. In the UK, that’s the Gambling Commission, who now have a monopoly on licensing for casinos that accept British players. But in reality, many online casinos are internationally based, and from time to time, they may be licensed in international jurisdictions - including those that are traditionally considered home-grown companies.

Part of the reason for this is taxation based - when you have international companies operating on the Internet, it’s easy for them to move their home jurisdiction to the most beneficial region for tax, or for multi-national compliance, or for a range of other commercial reasons. Regardless, it’s crucial that you play with a licensed operator, and that includes verifying any information you find on a casino’s website.

In general, the location of where the casino is regulated is not so important, for example, many are based offshore in Gibraltar, Guernsey, Malta or elsewhere. However, being licensed by a regulatory organisation, means you have a government authority to turn to if you feel the casino is violating its duty to you as a customer. As already mentioned, a prime example of such an organisation is the UK Gambling Commission which protects UK players.

Reputation is another key factor, and you can look into this by reading reviews and feedback from previous players. Some casinos have a strong marketing presence, but terrible reviews and ratings. Others are less visible brand-wise, but boast legions of happy, long-term players. It’s up to you to get to the bottom of this information in your due diligence, particularly when you’re dealing with any anonymous online casino promoters.

Rogue Online Casinos – Avoid at All Costs

If you end up joining a rogue/untrustworthy casino, then licensing is the least of your worries. Unfortunately, The World Wide Web can be an unpleasant place and there are many scammers trying to con people in the online gambling sphere. Look for players who have played at each individual casino before and read about their experiences. Are past players complaining about being scammed by a potential casino you are thinking of joining? Again due diligence.

All online casinos listed on OpenBonuses.com are safe and secure – so there is no need to worry about rogue operators.

Rogue segments exist in almost every industry whether it be finance, medicine or gambling – it’s just sometimes harder to spot in the online casino sphere. Reading reliable reviews is one way to make the correct call. If an online casino is in any way suspect, your research will go a long way to finding that out. Be Warned - if you do not read reviews, you might not realise until it’s too late.

Fairness and Game Integrity

When you play roulette at a land-based casino, you can physically watch the game unfold in front of your very eyes. Short of rigging the wheel (which can still be done, by the way), you can be pretty sure that what you see is what you get. But what about virtual games, where you’re interacting with software and hoping for a fair game? Game integrity and fairness is hugely important, and most players on a losing streak will at some point or another question whether the game is rigged against them.

Playing with licensed operators is a good start, but you should also be looking to find certification from auditors confirming the games are random, and confirming the RTP percentages you are told are reflective of accurate chances of winning. Reputable casinos make sure their games are audited as random, using random number generators that are thoroughly tested for fairness. This information should be available on the casino website, and you should be able to verify these with the third parties if required.

Make sure the UK Online Casinos have the Games you want to Play

You will want to make sure that you’re actually joining an online casino which offers what you are looking for. The selection of casino games and type of games is a very important area and one that sometimes maybe be forgotten in the midst of weighing up different gambling operators.

Does the casino in question offer games by your favourite software developers? Third party software developers supply most online casino games, and therefore, it is important to make sure they are supported. Popular ones include PlayNGo, Microgaming and NetEnt. These should indicate that you’re probably in for a fun and enjoyable gaming experience in terms of the graphics and in-game features, together with a fair chance of winning.

With regard to the different types of casino games, some casino sites specialise in table games such as online roulette, live blackjack or 3 card poker, whilst others may feature online slots. Some may cross over into both realms, ultimately, it’s up to you to do your research and due diligence, so you can decide whether you’re playing somewhere with an excellent range of games and more importantly games you enjoy playing to keep you entertained.

Fast Withdrawal Times & Flushing

One of the main woes for casino players comes when it is time to cash-out winnings. Players generally think that because their deposits are processed very quickly, that their withdrawals will also be processed just as fast. However, this is rarely true. Casino Operators need to verify and check that all payments they transact are legitimate in order to act in accordance with financial regulations and to safeguard their own interests. As a result, a delay of several days can occur between the initial cash-out and receipt of funds. However, some good casinos have extremely fast cash-outs with funds hitting your account within minutes. Do your research.

Flushing is a topic related to fast cash-out times. There are a number of online casinos that have a two-step payment process, whereby, funds that have been sent for withdrawal are held in a pre-processing stage. During this stage, players are allowed to reverse their withdrawn funds and start gambling with them again. This is frowned upon in the online casino world, as players tend to go on and lose all their money, which was initially meant to have been withdrawn.

Providing you are 100% sure you want to cash out - Manual flushing allows you to by-pass this process and move cash-outs straight to their processing stage. Some casinos have an option you can select during the withdrawal process, whilst with some others you will have to contact customer support and request them to manually flush your funds. This can speed up the amount of time you have to wait to receive your funds.

Customer Service

Customer service is of prime importance in the casino industry mainly because it’s usually the only chance you will get to speak with the online casino directly to discuss and resolve any problems or account issues. Initially, nobody expects to contact customer support, so it’s normally over-looked by players searching for the perfect online casino, however, it’s actually crucial to your gaming experience.

Look at the options and availability of customer support! Does the online casino in question have email only, or are there live chat and also phone support options available? Another point to bear in mind is when are the support agents available? Are they available 24 hours a day? These are the types of questions you should be researching by reading reviews enabling you to make informed decisions.

Summary

Doing absolutely no research is too risky and not worth taking when there is a wealth of information available to you. Why even take the risk, it is far better to approach the decision with your eyes wide open by reading as many online casino reviews as you can. Looking out for each of the important points listed above will not only help you become more familiar with what each casino has to offer, but potentially will also save you any inconvenience further down the line.

There is a big community hub of online casino enthusiasts. We have ratings on pretty much all legitimate UK casinos. Indeed, we even highlight the dodgy casinos you need to avoid. So, in a nutshell, read and learn from the past experiences of other casino players and take note of the casino reviews in order that you may make informed decisions as to where you should play online.
