Filtering Down The Best Online Casinos

In a fast paced World surrounded by rapidly evolving technological advancement, it’s no wonder why many people don’t have the time to research information and find the best online casinos. To be honest we don’t blame you! Most importantly when narrowing down the most suitable casino, it’s important to ensure you’re vetting what matters.

At the end of the day, you’re not really interested in carrying out all the due diligence, there’s a lot of it. All you want is clearly displayed online casinos ranked in order of relevance, key information displayed and off you go!

However although we have done this, for those that want to understand how we’ve done it, we’ve constructed a list on what to look out for.

Best Online Casinos Checklist

When it comes to identifying what qualifies as a good online casino, there’s a few pointers to help you decide. It’s never as simple as selecting a good casino based only on the Welcome offer. We’re going to highlight some of the key areas to always remember and to look out for.

How to Register (What to Expect)

Once you have identified the online casino or slot you would like to pursue, as well as reading the bonus terms and conditions, you are ready to register.

The registration process is pretty straight forward, although in some instances you may be required to present some identification to prove you are over 18, this process is also known as KYC (know your customer), a bit more about that later.

 

The registration process is as follows

  1. Register your details, ensuring your address and mobile number are correct
  2. Add or choose correct payment details, this will be used for both deposits and withdrawals
  3. Once you submit your registration form, you will have to verify the account via email
  4. Upon email verification you will be taken to the Casinos lobby
  5. Proceed to making a deposit (you will be asked whether you want to claim the bonus or not)
  6. You are now good to go.

 

Become a Better Player, Using the Online Slots Guide

We created an in depth Online Slots Guide to help players develop their understanding for Online Slot Games with the aim of becoming better players.

The Online Slots Guide covers every topic and breaks down the slot games likely to payout more and what to do to increase your chances. It’s a full packed Slots Guide that’s taken a lot of effort to put together, therefore be sure to read it.

Know Your Customer aka KYC

KYC - Know Your Customer

By law, all organisations offering a service to individuals required to be over 18 must carry out a KYC verification. This ensures the safeguarding of both the individuals as well as the business.

 

KYC, Consumer vs Business Concerns

From a consumer’s point of view KYC is there to ensure you are who you say you are and that you pose little or no risk to the service you are about to receive. While from a business point of view the KYC process ensures the business Is protected from auditing bodies, insurance liability and potential lawsuits. It also gives companies a measurement tool in terms of risk.

 

Automatic KYC Verification

You will not always be required to produce KYC documentation when signing up with online casinos, in most instances it is automatic and happens without you even knowing.

Once you have registered and proceed to the second page, the database would have scanned other databases to match your information, whether it is a bank or the local council.

So long as you have not recently changed address or phone number, you are likely to get through.

 

Manual KYC Verification

Some online casinos however will want to carry out the KYC checks manually, to which you will be asked to either scan the documents and email them over, or take a photo with your camera phone and upload them to your profile.

 

Approval and verification

Approval and verification are generally immediate, however in some instances if KYC has not been verified, it may need to go through the compliance team, who will then contact you to verify your details. This is rare; however, it can happen and can at times delay your registration verification.

Online Casinos Licensing & Security

Slots Safety and Security

 

Do you remember when online shopping first became a thing, and everyone was skeptical about giving out their card or personal details online? Well, the skeptics are still there, however times have changed across the industry.

Online casino and gambling is still looked down on due to the stereotypical negative associations it has with sex, drugs and rock ‘n’ roll!

Therefore, when it comes to laying down money and personal details no something you do not know much about, alarm bells do tend to go off!

 

Your Safety is Primary

All online casinos and slots promoted on this site are 100% legit. As we stated before online casinos have to be licensed to operate and in order to be licensed they have to be audited often by the gambling commission, software providers as well as financial institutions.

 

SSL Encyption & Independent Audits

To keep you safe from prying eyes, all online casinos have set an SSL encryption into their network. Whenever you fill in and send the online casinos sensitive personal or banking information while registering, depositing, or withdrawing, it is obscured.

This almost eliminates your risk of getting your account information compromised by strangers.

 

Online Casino and Slot Game Audits

The games used at online casino are some of the most rigorously tested in the world. You can see the independent audits conducted by eCogra by clicking the “Percentage Payout Reviewed by Independent Auditors” seal at the bottom of the website.

This monthly report includes certification that the games are fair, as well as the game returns discovered by the most recent randomness test.

If you do not see the seal, do not be afraid to contact customer support and ask them to send you that information. It is only fair to be comfortable with who you are sending your money to.

 

Top 5 Advisory Pointers to Keep you Safe

Despite all the above, there are a few advisory pointers we would suggest for you to follow:

 

Change your password regularly

Keep your username and password difficult to crack. Make sure to change your passwords regularly, where possible, mix your password with numbers, characters, lower and uppercase.

 

Clear your winnings out

If you are worried about your account being hacked, or someone else tends to use your phone, consider withdrawing your funds every week or month.

 

Never store passwords on a public computer

Never cache your passwords and watch out for cookies. Keep a list of passwords on a secure drive where you can access them easily.

 

Only trust reputable casinos

Look around for reputable online casinos, read honest player reviews, if you are a serious gamer, join some forums and exchange information. Bear in mind not everyone tends to agree, but you will generally get a good idea.

 

Listen to other players’ concerns

Some casinos have a track record of slow payouts, unhelpful customer support teams, or suspicious software. If a casino has been blacklisted for consistent problems with its operation, it is time to look elsewhere.

Gaming Software Providers

software providers - www.whichcasinos.co.uk

A casino software provider is the company behind the games you play. They are the ones that come up with the ideas, design the graphics, set the pay-out percentages, and code up the game using random number generator (RNG), this ensures all online casino games, play fairly and within the rules set by the regulators.

The same applies to online Live casino games, for example any casino hosting live dealer games is likely to be running on Evolution gaming or NetEnt Live software, as these are the two dominant names for that genre.

Other big names, you’ll see a lot of include, the likes of Playtech and Microgaming, these software providers host most games seen in the online casino market.

With so many options available out there, knowing ‘which casinos’ run on the most reliable software is important for both security and enhanced user experience

Accepted Payment Methods

Slots Guide payment methods

Banking online is now the most trusted, easiest, and quickest ways of transferring funds around. Online banking using any type of method was looked on with great suspicion in the formative years of the internet. But, these days there’s nothing on the internet that’s more secure.

Depending on your circumstances choosing an online casino that meets your depositing or withdrawal requirements is important, whether it be PayPal, Visa, Skrill, Klarna, Boku pay by phone or even Bitcoin.

Each option offers different withdrawal times.

 

Payment Method Restrictions

Online casino players should also note that some casinos may only accept certain payment method for deposits and not withdrawals.

Importantly, to note, as of April 2020 the gambling credit card ban will kick in, this means all online casinos will no longer be able to accept credit cards as an accepted payment method.

Although online casinos will have other suitable alternatives. For further information please refer to our Payment Methods page.

Online Casinos Game Options

Variation of Slots

Finding the best casinos and slot games online is not always easy.

Similarly, with thousands of casino and slot games available across all the online casinos, there’s bound to be something that meets your requirement. However, perhaps you’re specifically interested in online casinos or slot games operating on a particular software, such as IGTNetentPlaytechMicrogaming, or you prefer the live casino from Evolution gaming.

Either way, we have listed the best online casinos by software category and these can be found within our software topics.

Whether it be Live Dealer, Slots, or table games ensure your online casino choice meets your requirements.

Online Casinos Bonus Offer

Casino Welcome Bonus

 

It’s one thing to find the best online casino bonuses and another understanding what the offer means. At ‘which casinos’ we thoroughly understand your motive of getting more out of your hard-earned money when playing online casinos. Hence, we know that depositing money into an online casino which provides you with the best possible bonus and experience is of primary importance.

Therefore, our first suggestion to you would be not to judge online casinos by the size of the bonus offered. Instead ensure you understand the online casinos bonus terms and conditions. This will give you a better understanding of the bonus requirements, such as wagering to be met prior to converting your winnings into cash.

 

Look out for No Wagering or Wager free bonuses

Bearing in mind, some online casinos have no wagering or wager free bonus offers, so whatever you win is converted in cash you can withdraw immediately. You can use our free Wagering Calculator found on each page.

Nevertheless read the withdrawal terms and conditions as well as the use of language, especially if there’s spins involved. If you are only interested in wager free casinos, then you would be happy to know we have a dedicated page for the topic.

Players should also be able to identify if the bonus is promoted as ‘Free’ or ‘Bonus’, the difference is bonus requires a deposit to be made prior to being claimed while ‘free’ does not.

 

Use Our Free Wagering Calculator

The Free Betting and Wagering calculator, has been designed based on player requests as well as with simplicity in mind.

Unless your welcome bonus states ‘no wagering’, the bonus offer will have a wagering or staking requirement to the bonus. Knowing how much you can withdraw and when you can withdraw the funds you may have won, is very important.

The wagering calculator therefore allows you to simply add information readily available to you in order to get a total of what amount of money will be required for you to play through, prior to converting what you have into withdrawable cash.

 

Clearly displayed T&C’s

By law, all online casinos are required to clearly display their bonus terms and conditions, this is also known as salient terms or a summarised version of their full terms and conditions. We therefore filter through all this information for you and deliver an honest trusted verdict that clearly states what you get from the online casinos you’ve chosen.

Online Casinos Rewards & VIP Programs

VIP Casino

 

All online casinos want to retain your loyalty and the best online casinos tend to have a team dedicated to just looking after their most loyal players.

As you can appreciate, all online casinos are setup differently the same applies to the rewards or VIP team.

Smaller online casinos tend to reward their loyal players with free spins, matched bonus offers, and birthday bonuses. What you get from the smaller online casinos varies depending on the ‘Level’, you’re currently on.

Each Level is achieved depending on how long you’ve been a member and how much money you’ve deposited.

 

Understand the Perks as a VIP

The larger online casinos tend to have more financial muscle behind them, which also means, they can spoil you more as a loyal VIP customer. As a VIP customer, you’d get your very own dedicated account manager, this is the person go to individual if you’ve got any issues or have certain requirements.

However, there’s a lot more you can expect, such as, frees spins, cash rewards, enhanced bonus offers, quick deposits, high withdrawal amounts, birthday gifts, event tickets, and all expenses paid for holidays.

 

Online casino cashback offers

Depending on the online casinos, some offer cashback rewards, this is based on you receiving 10% of your money back should you lose back each time you play. Whilst other newer brands such as Trust Dice, which is a Bitcoin Casino, who reward players with TXT tokens whether they win or lose, these tokens are a company profit reward, think of it as shares.

Online Casinos Device Compatibility

Online casino devices

 

Most online casinos are compatible with all devices such as, desktop, mobile and tablet, operating on Windows, iOS or Android.

Generally promoted as ‘instant play’, this means the moment you visit the online casino website, your experience as well as game choice is no different to a downloaded app. Although, some casinos have downloadable apps for ease of play, players also tend to receive more promotions via their app. Again this is dependent if the online casino offers a downloadable app.

Online Casinos Customer Support

casino customer support

 

Perhaps one of the most important topics is online casino customer support.

Importantly, the customer support service offered by online casinos is of primary importance to most customers. Understandably, customers want to know there’s someone they can reach out to the moment they have a problem or an enquiry.

 

Customer Service Cannot be Underestimated

Customer care distinguishes a good casino experience from a bad one. The best online casinos tend to offer 24/7 customer service, whether it be via live chat, email, social media, telegram or phone. However,the smaller online casinos only offer customer care around dedicated times during the day.

To ensure we minimize the customer service problem that could be faced by our visitors, ‘which casinos’ provides you with first-hand information on the online casinos customer support working times and available channels. For assurance please check the customer service section with the review page for the casino in question.
