Mobile Casinos

Mansion Mobile CasinoAs you can probably guess from our name, we are really into mobile casinos. Due to the soaring popularity of smartphones, mobile-friendliness is hugely important when it comes to joining an online casino. Whether it’s at home or on the go, you want to have a seamless and fun experience when playing casino games online. Most UK online casinos have managed to make their platforms mobile-friendly; however, there are still casinos that provide a better experience than others. We have tested all of them, and you can find the results on our dedicated mobile casino page.

It’s important to remember that there are two different types of mobile casinos, apps to download and web-based casino sites. We recommend to sign up with a web-based mobile casino and here is why:

  • No storage space on your phone required
  • Same login across all your devices
  • Instant access to all games

There is also a common misperception that mobile casinos are light versions of its desktop version and provide limited functionality to players. While this was true a few years ago were happy to tell you that today, casinos on desktop and mobile provide all the same features such as depositing and withdrawing money, updating account information or playing slots and table games. In fact, mobile casinos probably offer a little bit more as players can enjoy casino games on the go. Anytime, anywhere!

Security at UK Online Casinos

Safety and security are incredibly important when deciding whether to join an online casino site and it’s one thing many new and regular players worry over. However, there are several large bodies and companies working together to provide players with a safe, secure and fun experience.

Licensing

For example, it’s compulsory that all casino operators providing gambling services possess a license issued by the UK Gambling Commission. To receive a license, UK online casinos must follow the strict standards and regulations of the Commission, which analyses the safety and fairness of games, as well as the technical security and player protection.

UKGC License

Most online casinos will also test the fairness and integrity of their games by using testing agencies which provide an analysis of the RTP (Return to Player) and RNG (Random Number Generator). The agencies include eCOGRA (E-Commerce and Online Gaming Regulation and Assurance), Technical Systems Testing (TST), Gaming Laboratories International (GLI) and the Gaming Associates. All of the agencies are recognised by the UK Gambling Commission and are completely independent from online casino software providers and operators.

Other European countries will have their own gambling authorities and some of the licenses you’ll see on casino sites will include the Gibraltar Gambling Authority, the Malta Gaming Authority, Antigua & Barbuda’s Directorate of Offshore Gaming and the Alderney Gambling Control Commission.

Customer Service

An integral part of any business is dependable customer service for when things don’t go according to plan. You might want to inquire about your withdrawal, request a chargeback, or ask about the latest promotions, and it’s essential that you can connect to an agent that speaks your language. The best online casinos, therefore, offer multi-language support around the clock via phone, live chat, and email.

Customer Support IconNow, while most queries can be solved immediately, sometimes you will have to wait up to a few days to receive a satisfactory reply. We’ve tested countless casinos and made the experience that live chat tends to be the best support method when it’s about general and non-sensitive queries such as questions about bonus and promotions or simple account detail updates.

For more serious queries, e.g., chargebacks, we recommend to email the operator because it means that you’ll have written proof of your support question which might come in handy later on. Generally, though, UK online casinos offer excellent customer support where the customer is king.

Technical Security

SSL Lock Browser BarCertified software and standard security technology such as SSL ensure that data exchanged between you and the casino cannot be viewed by any third-party unless you granted explicit permission. All transactions including deposits and withdrawals should use 128-bit encryption; the same banks use for their online services.

It’s easy to spot whether a gambling operator has implemented the required security mechanisms to keep your personal and financial information secure at all times. Before signing up with a casino site or making a deposit, check whether you can see a green lock in the browser bar either by itself or followed by the word ‘Secure’ (see screenshot on the right. If you do, then the site fully encrypts your data during file transfers. You can go ahead!

At SmartphoneCasinos.co.uk, we really care about your safety & security hence all online casinos on this site meet the security standards mentioned above!

Modern Website

Many online casino sites use the same software providers, making their websites and apps look incredibly similar, from game selection to the layout offered. We at SmartphonesCasino look at how user-friendly, intuitive, easy to navigate and reliable the websites are.

Online casino sites which score highly in this category will be recommended and casinos which also feature jaw-dropping graphics, great design and short loading times will also be considered. In addition, we also look at the contact information offered and how easily information is given to players, such as bonuses and payouts and whether the information is available immediately, or if websites require players to search through multiple pages.

Game Selection

Game selection is one of the most important points to consider when joining a UK online casino. The websites and apps need to offer a good selection of games as well as an exciting variety too. Most online casino sites offer the traditional games such as roulette, blackjack and slots, but which casinos offer new and fun variations such as multi-wheel roulette or blackjack switch or double attack?

You’ll find the traditional games at online casinos with no problem but casino providers should also offer less popular games, such as baccarat or sic bo, in order to appeal to more people and offer players more choices. The number of games and game variations offered depends entirely on the online casino, so it’s important to check out our reviews to find out more.

Return to Player (RTP)

Return to Player LogoRTP (Return to Player) is the term casinos use to describe the percentage of all the wagered money a game will pay back to players over time. These payrates are calculated over a long period of time and provide only an average return to player, so it’s not guaranteed that you will win this back. It’s important to consider which casinos have high RTPs as it means players will be more likely to earn money.

While the RTP completely depends on the game being played, most casinos publish their RTP for each game in the game rules on their website. Operators sometimes publish payout reports from the testing agencies mentioned above. The differences between the payout rates of each of the casinos do not differ much. In fact, most UK online casinos offer a high return to player rate with slight variations.

However, there’s a large difference between the RTP of online slots and land-based slots. In general, the payout percentages at brick and mortar casinos are much lower than online casinos, this is due to the land-based casino’s higher operating costs.

Bonus Offers

All casino operators provide different bonus offers to entice players. There are numerous bonuses offered, from extra spins to no deposit bonuses or cashback programmes. A good point to consider when joining a UK online casino is whether the casino provides bonus offers to only new players or regular ones.

As we’ve mentioned, there are hundreds of available casino bonuses around and many might appear great but after reading the fine print you’ll realise the wagering requirements or other restrictions make it almost impossible to receive the full bonus.

It’s important you research the bonuses offered and read the fine print to really understand how they work. To help you out, we’ve actually made a guide on best online casino bonuses and have reviewed which providers offer the best bonuses.

Payment Options

Just like the game selection offered at online casinos, it’s important to know which payment options are accepted. Deposits should be made easily and quickly, allowing players to jump right in when they’re ready and payouts should be an easy and exciting experience.

The best online casino providers will accept a number of different payment options, from traditional debit and credit cards to PayPal, Skrill, Neteller and much more. Players who want their winnings quickly will have to join an online casino offering speedy withdrawals.

It’s also important to remember that there may be restrictions on certain payment methods such as minimum and maximum limits on deposits or withdrawals, as well as fees. To help you out, we’ve reviewed which casinos are the best for debit or credit card, PayPal and pay by phone payment methods.

Live Dealer

Live Dealer BlackjackLive dealer games have grown in popularity at UK online casinos because they offer a real casino experience from the comfort of the players home. For those that don’t know, live dealer games feature real dealers and games who are streamed to the player directly. The user then plays the game in real-time while interacting with the live dealer who responds via stream.

Thanks to the fast internet speeds available today, streaming has never been easier and the quality remains perfect. Live casinos games are now incredibly popular and casino operators provide a large number of live games including roulette, baccarat and blackjack.

Live casino games do follow different rules from regular online casinos. For example, some providers may remove players from streams if they’re inactive and haven’t made a bet or two for several rounds. However, it is possible to rejoin the game later on.

Casino Software

When you sign up at a UK online casino, it’s important to keep in mind that most of them do not develop their own casino software. Instead, operators rely on third-party games developers so they can focus on what they are best at, offer bonuses and promotions to keep you happy as a player!

The best online casinos offer games from more than one developer and allow you to choose from a wider selection. NetEnt, MicrogamingPlaytech, Novomatic, and Quickfire, all count towards the most popular game’s developers for the UK market. Most brands we recommend offer selected games from two or more developers, but if not, we will explicitly state this in the casino’s review.

Online Casino Software

Generally, there are two types of online casino software available to users including downloadable and instant-play. Downloadable casinos are installed on computers and players are required to launch it to play games. Instant-play, however, is played in-browser and are far more popular than downloadable casino software.

One thing that’s important to remember is that online casino software is constantly improving. The game develops listed above are constantly working hard on providing players with the best possible experience.

Land-Based Casinos Vs Online Casinos

UK MapFor anyone struggling to make the decision between an online casino and land-based casinos, we’re here to help. There are various advantages to playing with an online casino, but there are also a few disadvantages.

For example, because online casino sites are, well, online, there are no size limitations. This means they can offer dozens of more games than a land-based casino ever could. In addition, online casinos sometimes allow players to try out their games for free and, most importantly, you don’t need to wait for someone to finish playing their game before you can enjoy it. Lastly, online casinos can be played whenever and wherever!

However, playing online means users miss out on the exciting and vibrant casino experience. Players won’t feel the excitement of playing with other players and will be unable to make friendships over their favourite games. Instead, players will be stuck at home and all alone.

But land-based casinos aren’t all that great either, and we believe they actually have many more disadvantages to them. For example, players need to physically visit the casino in order to play, they need to wait their turn to play and due to size limitations, the casino may not even offer your favourite game.

On top of all that, some casinos have limited working hours which means the games aren’t available 24/7. They also accept fewer payment methods but offer an entertaining and exciting environment to play in.

At both casinos, however, players will get to experience numerous benefits and bonuses for playing. It all just depends on what you, as the player, want.
