What we look for with online casino sites

When we consider online casino sites to feature on our website, we make sure to look at a few different criteria we deem important.

We are not limited to just these different factors, but we find that if the following points are positive, so will the overall outcome of the online casino reviews.

Let’s get started!

Welcome Offers, Bonuses & Promotions

One of the most important factors we consider are the range of offers, bonuses and promotions that are available to both new and existing online casino players.

Some online casino players may consider welcome offers and promotions as just gimmicks, but with more and more online casino competition, they can be considered to be one of the most important ways that online casinos can differentiate themselves from their competitors.

Although they may vary between different casino providers, there is usually always some form or offer available for new customers and existing members alike.

A welcome bonus might typically represent a percentage of your initial deposit in the form of a free bet, or other free prizes such as free spins or cash.

Some online casinos will also offer a “loyalty bonus” to players who have been playing for some time, and these bonuses can often be more generous than the initial welcome incentives. Loyalty bonuses are typically linked with how much money is wagered by a player.

And finally there is usually an ongoing promotion that provides additional free spins or cash prizes on certain games designed as regular surprises throughout your gaming experience!

Variety of Online Casino Games

There are plenty of different online casino games to choose from and it is not uncommon to see the same game across multiple sites. Therefore, we want to make sure there are enough different slots, table game options or other casino favourites for our readers.

The majority of games are variations on Roulette, Blackjack or Baccarat – with these three games standing the long test of time. The demand for these types of games mean that they will probably remain for a long time going forward!

But there are also more games in the categories such as slots, scratchcards, slingo and related, so it is not uncommon for a casino to feature hundreds of different games from these categories and more!

However, it is common to find the exact same games available on more than one online casino. This is due to the gaming companies providing the games to the online casinos. Generally speaking, the more gaming providers available, the better and more varied the range of games!

Deposits & Withdrawls

If you are adding money to an online casino account, you want to ensure it is not only secure, but that you can withdraw any winnings without any hassle or security concerns.

Most online casinos – especially in the UK – will allow players to use common banking options such as Visa and Mastercard, as well more unique payment methods like Neteller or Skrill.

Many players will also use e-wallets to make deposits such a PayPal for the sake of convenience. This is of more importance to some players when they are depositing money with an online casino based outside of the UK.

Withdrawing your money should be as easy as depositing it.

Players are often able to withdraw funds from their account by using the same payment method as they used when depositing. This can be useful for a player who wants quick access of any winnings, or are familiar with the banking process and waiting times.

Some casinos also offer players different a traditional option like bank transfer – which usually takes longer than other methods but ensures that you don’t have to rely on a third party to handle your data.

Unique Features

Many casinos will have very similar features, promotions, games, etc. However, in an effort to set themselves apart, some online casinos introduce unique features for their players benefit.

This may be in the form of no deposit bets, or referral bonuses where you earn cash for encouraging your friends or family members to get involved too!

Mobile & Desktop Playability

Online casinos have traditionally been designed for desktop devices, yet more and more players are choosing to play on mobile devices. The best UK online casinos will provide a similar experience on desktop and mobile devices, with responsive design.

If you’re playing from your phone or tablet then it’s not just about the graphics, but there are also considerations such as accessibility, speed and device compatibility.

The good news is that many of these issues have been dealt with already because so much time has passed since their introduction.

You typically get the option to play most of these online casinos on mobile through the web app, or by downloading a specific mobile app from the Apple App of Google Play Store.

Contact & Customer Support

Most of the time, you won’t ever need to contact help or support, but there may be instances when you require some help.

If you do, you want to ensure that it is easy and hassle-free to do so.

Websites with good customer support typically make it easy and obvious to contact them. This can include a live chat features, a help guide, FAQs or other documentation that is properly considered for players needs.

Every casino should have live chat available on the website for customers to contact them. The very best casinos will have 24/7 support, but be aware that some online casinos will have opening and closing times where no support is available.

Although not crucial, you should ensure that it is easy to complete and online form or find a direct email to contact in the absence of 24/7 support!

Licensing & Legislation

An online casino might look legitimate on the face of things, but you want to ensure that the correct licensing and legislation is in place should something go wrong.

That’s why it is crucial that you check that the casino is licensed by a reputable regulatory body before you sign up.

Most online casinos will include their licensing information in the footer of their website. Here you may typically see some sort of endorsement from companies such as the UK Gambling Commission or Alderney Remote Casino Licensing.

There are others also, so make sure to consider these carefully before deciding to part with your cash!

New Online Casinos

Just like anything online these days, online casinos come and go as popularity and user interest changes.

This means that new online casino sites appear with increasing frequency and as such it is important to keep up-to date with which sites are the best and most popular.

New casinos tend to appear faster than we can review and write about them. So if a casino is not present on our site does not mean we don’t think it’s good – just that we haven’t got round to it – yet!

Best Online Scratchcards Sites in the UK

Scratchcards are an exciting and accessible way to win a huge amount of cash on your favourite game, so it’s worth investigating the best online casino sites for scratchcard enthusiasts.

Whether they are called online scratchcards or instant plays, either way we have you covered in our dedicated page to the best online scratchcard sites.

Best Online Casino for Slots

Online slots are the most popular type of casino game in many parts around world, as they offer a great deal more variety than traditional card games or table-based online casinos and scratchcard sites.

Online slots generally make up the biggest range of games available, with options for progressives and other features that can lead to huge jackpot wins.

Best Online Casino for Slingo

Slingo is a relatively new casino game format, a mix of slots and bingo which is where it gets it name.

It’s a relatively slow-paced game, that offers players the chance to win big prizes for completing particular layouts using a series of numbers – like bingo – and reels – like slots.

Best Online Casino for Roulette

One of the oldest and popular casino table games is roulette. Everybody knows the traditional Roulette game, so they’re the same on all sites right?

Not quite.

Online roulette games vary from casino to casino and there are many different variations of roulette available.

There are multiple betting options, including American and European Roulettes- with the latter offering more possible bets than other versions but slower gameplay as a result or try entirely new styles like multiwheel where there is an array on one wheel to choose from for your spin!

Best Online Casino for Blackjack

Blackjack is another game that has been popular for many decades. When it comes to online blackjack games, there are many variations to the rules and gameplay that can be offered.

Best Online Casino for Baccaratt

The last of the three classic casino table games, online Baccarat is another game available for online casino players.

Online Baccarat is popular online as a result of the rapid gameplay and simplified rules. The aim is to predict if you think a hand has more or less than half points in total, with shuffles taking place after every round so that hands are dealt from new decks each time- this means there’s no need for strategy like when playing other casino games such as Blackjack!

Best Online Casino for Poker

There are loads of different variants of poker that you can play at online casinos, such as Texas Hold’em, Omaha Hold’em and Seven Card Stud.

Yet, online casino sites are always looking for new ways to keep players entertained, offering new game styles to choose from and exciting customer promotions.


Which Online Casino has the Best Payout?

There are a number of factors to consider when deciding which online casino has the best payout.
