What’s the Best Online Casino FAQ

Can I win money by playing in the casino?

This answer is too simple: absolutely yes! However, you must be aware that an online casino cannot be considered a source of income. While you could also win large sums of money, be aware that most players lose money in the long run.

It is precisely with the money of their players that the casinos are profitable.
If your goal is to win money, forget about online casinos; if, on the other hand, you are looking for fun, playing online casinos can be a pleasant way to spend your free time.

Are the casinos on this page really the top 20 UK Online casinos?

If you have visited other online review sites, you may have noticed that the best online casino lists are sometimes very different from each other. The reason is that there is no absolute best site and the preference depends on objective factors, but also on a subjective evaluation by the reviewer.
In addition, the subjective evaluation of the player is at stake, which can affect these rankings, if they take user feedback into account.

What are the objective factors?

The objective factors for evaluating the best casinos in the UK are the safety of the site, the availability and variety of games, the usability of the site from your computer, tablet, smartphone or app, ease of depositing and speed to withdraw money, quality of customer service, presence of bonuses and promotions, just to name a few.

What are the subjective factors?

It depends … and it can vary from person to person. These are those factors that can change based on the type of player, experience or past experiences, his preferences or simply based on his expectations, which in turn depend on the information he has.

Let’s try to make some examples. An experienced player tends to play and spend a lot more than a newbie. For this, he will prefer a casino with an inviting VIP system, while the newbie may be looking for free spins, no deposit bonuses or no wagering bonuses.
A player who prefers to play blackjack will be less interested in the variety of slot games, while a slots lover will not care if the live casino is missing.

Expectations also play a fundamental role. If you have played in a casino where customer service was bad or even absent, you will be more aware of how important this function is. You will probably only be interested in UK online casinos that offer live chat and answer your questions promptly.
Obviously, these are just generalizations to make you understand how much the concept of the best online casino can change from person to person.

When can an online casino be considered safe?

The basic requirement is being legal. In the UK, an online casino is only legal if it has a license issued by the UKGC.
Another necessary condition is that the transactions and other sensitive information you share with the casino are protected by an SSL encryption system.
Also, you want to play in a casino where the games are tested and the odds of winning reflect the stated RTPs.

How should the usability of the UK Best Online Casino be?

By now, most users connect from mobile, so the site must be responsive and easily accessible from all types of devices.
Speed is also an essential element of usability for the best online casinos. You want to avoid unnecessary elements that slow down the loading of the site, because this can compromise the gaming experience.
In order for a casino to be considered usable, it must allow users to easily find the most important functions: games, bonuses with T & Cs and support.

Does the Best Online Casino need an app?

When a casino provides you with a downloadable app, it certainly gives you an additional option.
Some may like a casino app if it improves usability and offers additional features.
However, many players consider it a waste of space on their smartphone, especially if the site is optimized for mobile browsing.
The app is most often used by casinos to create push notifications, in order to make players play more often, but it is not absolutely necessary, not even for the best online casino.

What are the payment methods of the best online casinos in the UK?

Nowadays, there are so many ways to securely deposit money. The best online casinos in the UK give their users as many options as possible.
Among these, there are main debit cards such as Visa, Mastercard and Maestro; e-wallets such as PayPal, Skrill and Neteller.

Even though the best online casinos guarantee 100% encrypted and secure transactions, they still offer payment methods which do not share any information.
Among them, there are prepaid cards like PaySafeCard.

Another payment method that is becoming increasingly popular is Pay by mobile, where you just need to verify your phone number. In this case, you are charged the following month on your phone bill if you have a contract, or the money is deducted from your phone credit if you pay as you go.

For the traditionalists, there is always the good old bank transfer.
Many other payment methods are born every day and the best online casinos in the UK try to make them available on their online platforms.

How can I recognize a deceptive / illegal casino?

A possible sign of a casino’s deceptiveness is the presence of a particularly aggressive welcome bonus. Illegal casinos, in fact, attract new players with this lever and then put conditions that make it practically impossible to win money.

Illegal casinos translate their site into several languages, because they don’t have to worry about having a license for each country where they operate (illegally), allowing payments with only one currency.
While these signs don’t necessarily mean we’re dealing with an illegal casino, a bell should ring in your head.

Fortunately, there is a way to certify whether a UK online casino is legal or not.
A legal casino has a link to the Gambling Commission website, where you can check the status of the license.
An illegal site does not display the UKGC badge, or, in a fraudulent way, does so with a broken link or without.

Why does the casino need to verify my identity?

ID Verification is a standard process for any legal casino. The first purpose is to confirm the user’s age of majority.
The casino also controls the user’s residence to prevent him from connecting from anauthorized countries and to confirm eligibility for bonuses.
Furthermore, the casino has the responsibility that the player uses a payment method in his own name.
