Getting Started at Top Mobile Casinos

Wifi Signal

To play at a real money mobile casino, you need to have a smartphone or tablet that allows you to access the Internet. If you have an iPhone or Android phone, e.g., Samsung Galaxy, make sure that WiFi or mobile data (3G/4G) is enabled. Since mobile casino games cannot usually be played offline, please also keep an eye on your data usage plan when playing on-the-go. Luckily, most mobile casinos are very lightweight nowadays, and so this shouldn't be an issue.

Mobile Website vs. Native App

To get started, you first have to decide whether you want to download the casino's iOS/Android app or head straight to the mobile casino website in your browser. Native apps used to be a natural choice, but with technology advancing rapidly, gamers have quickly been realising the benefits of playing games inside the browser.

Casino games have evolved into high definition gaming experiences with thrilling graphics and complex gameplay. To achieve this sophistication, it requires a lot of resources which make them large in file size. Operators like Microgaming are aware of this dilemma and tend to offer light versions of their mobile casinos with a limited selection of games when downloading from the app store. Now, if you want to play additional games, you have to download them separately one by one. This is not only cumbersome, but it also takes up plenty of storage on your mobile phone or tablet.

Playing online doesn't require any of this. By signing up on the mobile casino's website, you gain immediate access to the full range of mobile slots and other casino games. Since the casino hosts all resources nothing is stored on your device! We know this can sound a bit technical and overwhelming, so we summarised the key benefits of both in-browser play and app download in the tabbed table below.

  • No download required
  • Immediate access to full game selection
  • Quick sign-up
  • Download through the app store
  • Limited game selection
  • Possibly disturbance through push notifications

Bonus Offers & Promotions

Is there a better way to enjoy playing your favourite mobile games with other people's money? Most mobile casinos allow you to do exactly that! Gambling operators are very generous when it comes to bonuses and promotions as they primary goal is to create an unforgettable experience for their players. For UK players, there is a great range of different bonuses such as welcome bonus, extra spins, no deposit bonus or reload bonus, and each operator offers a slightly different set of promotions. As this can quickly become overwhelming, we tested all major mobile casinos and picked the ones with the best bonus offers. Learn more about our findings or just check out this month's hottest promotions.

Safety & Fairness

An enjoyable player experience is not just all about thrilling graphics and generous rewards. It's immensely important to ensure that your data is safe, winnings are paid out in time, and all casino games comply with fair play regulations. Therefore, we require online casinos to excel at the following categories to have a chance to appear on our site.

Casino Licenses

We only recommend casinos that hold the UK Gambling Commission and the Malta Gaming Authority licenses as this ensures that the casino has met all criteria that allow the safe and fair operator/player relationship. A mobile casino that operates without a permit can technically do whatever it feels like and therefore does not offer legal gambling as per definition under the Gambling Act 2005.

Customer Service

An integral part of any business is a 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. Top mobile casinos address this need by offering 24/7 customer service in your language via phone, live chat, and email. Most queries are answered immediately, but the longest you have to wait for a reply tends to be less than 48 hours.

Technical Security

SSL Secured

Certified software and standard security technology such as SSL ensure that data exchanged between you and the casino can not 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. Also, mobile casinos should be certified by eCogra which guarantees fair play and confirms the payout percentage of mobile slots and all other casino games.

Banking Methods

Every good online casino that we tested offers a variety of payment methods to give you full flexibility for your deposits and withdrawals. You will be able to play with credit and debit cards, e-wallets such as Neteller, Skrill or PayPal, and more traditional payment methods such as bank transfer and cheque. To find the best mobile casinos for each method, please click here.

Casino Software

When you sign up at an online casino, it's probably 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!

888 Casino

The best mobile casinos offer games from more than one developer and allow you to choose from a wider selection. NetEnt, Microgaming, Playtech, 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. An exception to the norm is 888 Casino who developed their own casino software called Dragonfish. They are doing a fantastic job and also managed to offer some of the most popular games outside their own software as well, so we highly recommend to go check them out.

Mobile casinos focus on real money players, but most operators allow you to try out their games for free. In such case, the casino will provide you with coins that allow you to play mobile slots and other games just as you would with real money. Please note that you won't be able to cash out any winnings when playing with free coins.

No, certified mobile casinos give you the same chance to win the jackpot as any hotel in Las Vegas. Actually, since you receive more bonuses and promotions when playing online, your chances to win big might even increase a bit.
