How We Choose Our Online Casinos

There are a number of online casinos which are all vying for your custom and it can be difficult to know which site will suit your needs. Luckily, here at Casino Billions we’ve rated and reviewed each of them and will provide a detailed breakdown of the key aspects.

During our extensive search of the top UK casino sites we have focussed on:

Welcome Bonus/Promotions

Every UK casino site will have numerous promotions which are designed to entice new customers to use their product. These can range from a straightforward bonus through to a number of free spins. There are a huge variety of bonuses available and each of them will come with terms, conditions and wagering requirements. We look at which sites offer the best promotions and how to qualify for each of them. VIP packages and loyalty schemes are another huge part of the online casino experience and we look at which of these offer the best all-round experience for the user.

Deposit Options

Every user will have a preference when it comes to finding an online casino site and we take a look at which sites offer the greatest variety of methods. We explain which sites have minimum deposits and whether the casino charge for using a particular method.


There are more online casino games than ever before and the sheer variety can be overwhelming for casino users in the UK. Casino Billions takes a look at some of the most popular games and the kind of offerings available to new players. We also take a look at which sites offer a free-play option which enables players to practice before spending their hard-earned cash.

Customer Support

Some casinos are renowned for their exceptional customer support and we take a look at which sites offer a range of ways to get in touch and focus on response times and helpfulness. Most casinos offer 24/7 support and we look at which sites make their players feel at ease.

Security and Safety

Arguably one of the most important factors is ensuring that users feel safe and secure whilst enjoying the casino product. We will focus on a number of sites who place the safety of their players at the forefront of their responsibilities. We explain what to look for before signing up for an online casino in the UK.


Once users have signed up to an online casino, they are likely to play on a regular basis. Most sites offer a VIP service which rewards those who deposit into their account on a weekly or monthly basis. We look at what each VIP service offers and whether it’s worth signing-up for their bonus scheme.


Playing casino games via mobile or tablet is increasingly popular and here at Casino Billions we focus on which sites offer a slick app or mobile site which provides all of the same advantages of a desktop site. We focus on compatibility, how to download each app and how each casino ranks when it comes to playing on the move.

Cash Out

We focus on whether each online casino makes it straightforward to cash out any existing winnings. We ask whether it is possible to set a ‘Pot Limit’ and whether the site requires additional ID checks before allowing money to be cashed out.

Payout of Games

Each online casino will have its own pay-out system and we focus on whether each product remains transparent and sticks to its promised pay-out rate. We look at the percentages involved and how likely players are to strike it lucky!


Every casino should be governed by a regulatory body and we will pay attention to the legality involved with each UK product and whether they are adhering to the gambling laws. In the UK, the gambling commission regulate each and every online casino and there are a number of sites including Gamble Aware and Gamblers Anonymous which are available for players who may require their services.

Online Casino Bonuses

There are a huge variety of online casino bonuses available and these can be hugely beneficial to new players in the UK. Luckily, users are able to sign-up to multiple sites and take advantage of these generous offers.

These sign-up promotions play a key part in our ranking of each online casino and they come in a variety of forms. We will provide details on what to look for and how to claim these outstanding offers.

The most common form for a bonus to take is a ‘matched deposit’. This relies upon the new players signing-up and immediately funding their account. The online casino will then match that amount offering users some house money to play with.

For example – With a 100% match bonus, placing £50 in your casino account would trigger an additional £50 from the operator.

Occasionally some casinos offer new players a no-deposit bonus but these are rare. Most UK casinos will also offer a number of free spins. These are usually restricted to a certain number of games. Some operators will specify ’50 free spins on XXX…’ and this is a great way of getting started and will help players familiarise themselves with a particular game.

Bonuses are just restricted to new users so once you’ve signed up and got your feet under the table, you’ll be able to take advantage of some excellent regular promotions which could include reload bonuses, free spins on a new game or a % return on your next deposit. Our reviews will also take this into consideration.

Casino Games

Online UK casino sites are constantly adding to their selection of games and there are a huge number of options for players to get stuck into.

Casino games such as roulette, blackjack and baccarat remain extremely popular and all online casinos will offer all of these. Many operators now have a live casino which gives players the feel of being in a real-life casino with dealers broadcast onto the screen to add to the authenticity. Roulette players feel at ease with a genuine wheel as opposed to a computer generated alternative.

Most casinos will also offer a variety of these ever-popular casino games. There are often low-stakes varieties for those who wish to play with just a small amount of cash. American/European roulette are also offered whilst some casinos now offer over 30 different varieties of blackjack. Casino Billions will carefully assess the amount of traditional casino games offered into our ratings.

Slot games have also grown in popularity over the past couple of years and most online casinos now offer a huge variety of these. With the advances in technology, computer generated slot games have become increasingly speedy. Most of these games are themed with popular film franchises or TV shows used to attract players to that particular product. 3D graphics and HD technology has improved slot games over the past couple of games and every new player will soon develop their personal favourites.

We focus on whether each operator offers a diverse range of slots and how many pay-lines are offered on a typical spin. These games also come with a variety of bonus levels including ‘Wild Symbols’, ‘Scatter Symbols’ and ‘Multipliers’ all of which offer players an opportunity to win big.

Other options include Video Poker Games which remain extremely popular and offer quick-fire returns for players. There are a number of special features within these. Bingo games also feature heavily and many of these are straightforward to play. These come in a variety of forms and the returns often depend on the amount of balls in the draw.

Most sites will also offer live poker games which take place on a regular basis and offer users the chance to outwit their fellow players.

Tips And Strategies

Playing online casinos is extremely enjoyable but inevitably, making a profit is the aim of the game for most players.

If the casino offer a free-play facility, it is advised to take some time testing a number of casino and slot games to ensure that you are comfortable with the game-play and pay-out structure. It is advised to bide your time before playing for cash. Start with small-stakes and there is the possibility to gradually increase them once you are comfortable in the online-casino environment.

It is advised to have a realistic idea of when to cash-out. For example if you start with £50 and you suddenly find that you’ve got £200 in your account, it can be extremely tempting to continue playing. Experienced and patient players know when to cash-out some of their winnings before returning to the game later that day.

You don’t always have to return to a winning game. If one particular slot has recently paid out a huge jackpot, exploring alternatives could be potentially lucrative. Although many players will find some games to their liking, if you aren’t finding it a profitable experience, it could be best to try something new.

Mobile Casino Apps

It is now possible to play top casino games on the move and with the advances in technology, an increasing amount of online casinos have launched dedicated apps.

Players are able to unwind at home or take a few spins on their lunchtime and it couldn’t be simpler to get started. Our reviews will focus on the mobile product and how each casino has adapted to the increasing demand for gaming-on-the-go.

Most companies offer downloadable apps for both iOS and Android enabling a quick and easy installation process for new users. They rarely penalise their mobile users and all of the same games are available, Wi-Fi or 4G permitting. Operators have recently added features such as live casino dealers to their mobile product whilst it is also possible to deposit or withdraw using a mobile or tablet.

Not every player will wish to download the app and it is also possible to access the same great range of games through a mobile browser. It provides a genuinely immersive experience for users and these products are likely to improve continually in the future.

Payment Methods

Enabling players to have a wealth of payment options is vitally important and most online casinos offer a terrific portfolio of methods.

These vary from credit/debit card through to Bitcoin. Depositing through e-wallets such as Skrill and PayPal is an extremely popular of funding accounts and we will focus on which options can be utilised by new players.

Some casinos will offer a minimum deposit whilst others place a small fee on particular methods. It is always advised to check before signing-up.

There are a multitude of different options and each player will have their preference. It depends on the financial situation of each individual casino user and that is something we factor into our reviews.

Online Casino Software Providers

Online casinos are powered by their software providers and most of them will be partnered by a familiar name from the world of online gaming. A poor software provider can make or break an online casino.

Players require slick, straightforward and enjoyable game-play and a decent software provider will help ensure there are very few glitches and bugs are infrequent.

Names such as Net Ent, Bet Soft and Play Tech are synonymous with excellent gaming and seeing these trusted providers is always the sign of a good online casino.
