Internet’s #1 Resource for Online Casinos

Whether you are new to the exciting world of online gambling or a seasoned veteran looking for a brand new online casino to sign up – you have come to the right place! At present, there are thousands of online casinos circulating the Internet and more which are launched every day, so to help gambling enthusiasts narrow down their choices, our team at BestUKOnlineCasinoSites.com has filtered through the good and the bad to only present the truly exceptional gambling platforms.

All of the online casinos featured on this site are fully licensed and regulated by the UK Gambling Commission and other official authorities, so you are guaranteed to be wagering on legal and fair-to-play websites. For these leading online casino sites in the UK to receive a coveted rating at Best UK Online Casino Sites, each brand had to prove that they will provide no-less than an enjoyable experience. They are assessed in a range of different areas starting with the welcome bonus to their wide gaming library, fast withdrawals, and fulfilling promotions and loyalty programme.

How to Pick the Best Online Casino Site

Choosing the best online casino is a completely subjective choice which depends on your opinion of what casino best suits you. With that said, there are some factors to take into account before officially choosing a gambling network, such as:

Safety and Fairness

An important aspect to know is who’s regulating and licensing the casino. The best three gambling licensing bodies for UK players are the UK Gambling Commission, Malta Gaming Authority, and the Gibraltar Gambling Commission. The operators presented on this page are licensed by at least one of these establishments, ensuring that they can be fully trusted to play all day, every day. Also, the casinos need to have a random number generator in place to ensure complete fairness for winning cash prizes.

Versatility

Ease of accessing the online platform, whether it is from a desktop web browser or mobile app, is crucial to the player’s experience at the gambling platform. Ideally, the online casino must have an attractive and responsive interface which can be loaded onto any device and operating system i.e. iOS and Android. Nowadays, most online casinos have opted to create a free-to-download app which is compatible with mobiles and tablets and allows its players to do everything similarly as if they were using the desktop version. This includes playing their favourite games, depositing funds into their account and requesting withdrawals, and contacting the support team. However, for brands that do not have a mobile app in its repertoire yet, the platform will still be accessible through a web browser where they will find that the site has been adapted to perfectly fit the smaller screen. Playing on-the-go is essential for the modern casino player as it is a compelling way to pass the time when they are out of their house and away from their home PC, not to mention, convenient. We have made sure that our online casinos offer at least one method of mobile play, but there are a great few which have been customised to provide both options.

Gaming Library

Our array of online casinos is powered by the best gaming software providers in the world – Micrograming, NetEnt, Barcrest Games, Evolution Gaming, Real Time Gaming, Yggdrasil Gaming and so on. While there are dozens more in the industry, these are the main suppliers offering outstanding graphics, sounds effects and gameplay. It is quintessential to sign up to a platform which has a rich gaming library to keep you entertained for hours. There has to be a mixture of classic and newly-released games to keep you on your toes. Most online casinos are dominated by video slots, followed by table games, video poker, and some bingo and lottery. A recent development is the addition of live casinos where players can go head-to-head against dealers (croupiers) in real time across a variety of casino table games and gameshows from any location, including the comfort of their own home. Our list of recommended online casinos each provides a gaming library with hundreds of exhilarating titles ranging from different themes, features and bonuses.

How to Pick the Best Online Casino Bonus

The initial tell of recognising a strong online casino is by their welcome bonus. The majority of notable casino brands want to set their new players off to a great start as it guarantees that they will be back for more. Therefore, the online casino will utilise either of the following welcome offers:

  • No Deposit Bonus
  • Match Deposit Bonus i.e. 100% bonus up to £500
  • Free Spins

Be sure to check whether the welcome bonus applies to your first deposit or if it is a package and is split between your first few deposits. Some online casinos provide a welcome bonus that covers up to the player’s first four deposits! Lastly, players must have a clear read through the Terms and Conditions of the welcome bonus for its wagering requirements.

We have gathered a range of online casinos and welcome bonuses (and wagering requirements) to allow you to pick the one that looks both generous and easy to claim. The wagering requirements for these welcome bonuses are realistic and easy to clear, so you can quickly cash out your bonus money afterward.
