What can you find on the best mobile slots sites? 

As experts in the online gaming industry, we know what goes into making a first rate mobile slots site. Below you’ll find a range of useful tips and advice to help you find the best places to play slots on mobile phones and tablets.

A huge selection of games from the best software providers 

Since the advent of HTML5 technology, the biggest development has been the way in which online casinos are able to offer a far greater range of mobile slots than ever before. Most of the mobile casinos that we recommend here feature large numbers of games by multiple developers, so that players have enormous choice and variety, with all categories of games available.

All of the leading slots developers produce their games in mobile-compatible versions, and these games are now of such high quality in terms of visuals, sound effects and gameplay that there is little or no difference to be found when you play slots on mobile or at a desktop site.

In addition, when new games are released by the major studios, the mobile and desktop versions are available to play at the same time, whereas once upon a time the mobile slot release often lagged some way behind the desktop version. This has meant that the overall range and number of mobile slots you can play on your phone or tablet is equally as large and diverse as you’ll find when playing on your laptop or desktop. 

The only exception to this is if you have a particular liking for the earliest Microgaming and Playtech 3 reel, old school slots. The majority of these games aren’t available in mobile versions, but as the number of these games is quite limited, not too many players will be missing their favourite titles when they play slots on mobile. 

Building on this, some newer producers and operators now take a ‘mobile-first’ approach, where the mobile versions of games actually takes precedence, and the slots are developed specifically to be played on this platform. This has been a bonus for players both in terms of the range and availability of games, but also the quality of the gameplay, as the smaller screens of mobile phones and tablets have been taken into consideration right from the beginning of the design and development process. 

Overall, this means that you can play just about every type of mobile slots game, by all of the major game producers, regardless of the playing platform that you prefer.

Best Mobile Slots

What jackpots can you win when you play on the go?

Playing mobile slots does not in any way preclude you from winning the biggest jackpots. Mobile slots games feature all of the same payline configurations, bonus features and free spin rounds as the corresponding desktop versions, so there is no diminishing of the gameplay nor the wins when you play slots on mobile.

This includes progressive jackpot slots, and all the major titles from the biggest jackpot networks — including games like Mega Moolah (Microgaming), Mega Fortune (NetEnt) and slots in the IGT Mega Jackpots networks — can all be played on your mobile phone or tablet.

In fact, some of the most recent enormous jackpot wins have been won playing slots on mobile — the current world record payout stands at €18,915,872.81, and was landed by a player playing Mega Moolah on an Android mobile phone. Several other recent life-changing wins have also been recorded by players on their phones, and so anyone who thinks playing mobile slots means that you can’t win big needs to think again.


The best mobile slots bonuses with fair wagering requirements

The mobile casinos that we feature here all offer new players signing up a range of different welcome bonuses. These can include no deposit bonuses, deposit match bonuses, and free spins as part of a signup deal, as well as other types of incentives.

However, as appealing as any bonus may appear at first glance, there is usually more to it than the headline figure. When you are trying to calculate the real value of a bonus, there are some other factors that you need to consider.

The first of these is the wagering requirement. This is the number of times you have to wager any bonus you receive (or any winnings made from playing with the bonus) before you are able to cash out. The industry average wagering requirement currently stands at 40x, which means that if you receive a £100 bonus, you need to wager a total of £4,000 before you can withdraw any of the bonus or bonus winnings. You will, however, find some sites where the playthrough rate is lower, while at others it can be as high as 60x.

When you are choosing a mobile casino site, you should always take the wagering requirement into consideration, as well as whether the playthrough applies only to the bonus amount you receive, or to the bonus plus your deposit. This can significantly affect the overall value and fairness of any welcome bonus, so the best mobile slots sites will offer bonuses with a reasonable playthrough, where the T&Cs make clear the specific requirements of the deal.

Similarly, the way in which the bonus can be cleared is also important. Most mobile slots at our featured sites will clear the bonus at a rate of 100%, so that every £1 you wager on slots on mobile counts as £1 towards the playthrough. However, at some sites there are exceptions to this, with selected slots contributing at a lower rate. Also, you need to be clear whether or not progressive jackpot slots make a contribution to clearing the bonus — again, at some mobile casinos they do, while at others they don’t.


Secure mobile payment options

At the best mobile casinos, UK players have a range of secure payment options available. At most sites, this will include debit cards, as well as direct bank transfer, although there are some other more secure and efficient payment methods that are recommended for use at mobile slots sites.

Using Boku at a mobile casino

One of the most popular and easy banking methods to use is Boku. This is a payment system that enables you to make payments into your casino account through your mobile phone, with the sum you deposit being either added to your mobile phone bill, or deducted from your pay-as-you-go balance. 

There are a number of advantages to using Boku for playing slots on mobile. Firstly, it is available for users with phones or tablets on all the major UK mobile networks, including Virgin Mobile, BT, O2, Three, Vodafone and EE. 

It is also the ideal solution for those players who don’t want to use a debit card, or share their bank details with a casino, plus you don’t have the inconvenience of having to set up a new account or remember yet another password. You also don’t have to use PIN codes, or purchase vouchers in advance.

Boku is also a very secure payment method, as every transaction needs to be authorised via text message, and you also get a receipt for every deposit. You don’t need to share your personal or financial details with any third party providers, adding to the overall security.

A further advantage of Boku is that you can use it online at a range of other online stores and service providers, including Google Play, Spotify, Facebook and Sony.

However, there are a couple of drawbacks to using Boku as your preferred payment option. Although it is a mobile method, it is not universally accepted at every mobile casino site. In addition, the amount that you can deposit is limited to £30 per day (£10 in a single transaction). Some casinos will also charge a fee for processing deposits using Boku, which can be as much as 15% per transactions, while at some sites using Boku to make your first deposit into a new account may preclude you from taking advantage of a signup deal.

A further disadvantage is that Boku is not available for withdrawals, so you will need to have an alternative method in place when you want to cash out.

Using Pay By Phone

Another popular payment method at our featured mobile casinos is Pay By Phone. This operates via the Payforit platform that is run by four of the major UK mobile phone carriers — EE, O2, Vodafone and Three. This is a shared system that has been set up to facilitate mobile phone payments, and there is no account to set up or manage in order to use Pay By Phone.

The system works in a similar way to Boku, in that when you make a deposit into your mobile casino account, the sum is either charged to your phone bill or is deducted from your pay-as-you-go balance. 

There are a number of advantages to using Pay By Phone. For instance, all you need is your mobile phone, and the system is very simple to use. There are no fees (although mobile slots sites may charge you a handling fee) and it is a very secure payment method, as you are not required to share any of your financial information. 

Like Boku, there are some disadvantages when you use Pay By Phone. There is a £30 daily deposit limit in place, and you are unable to use it to make withdrawals from your mobile casino account.

Other secure payment methods

The best mobile casinos also make it possible to use a variety of other secure payment methods, meaning UK slots players should always be able to find a payment option that is accessible and convenient.

These include PayPal, e-wallets like Skrill, Neteller and ecoPayz, pre-paid methods like entroPay and PaySafe Card, while Trustly is available at a growing number of mobile sites.


Mobile casino safety and security

For players who choose to play slots on mobile at our recommended sites, you can be sure that you will get a safe and secure gaming experience.

All of our featured sites are licensed and accredited by the UK Gambling Commission, meaning that they have clear policies in place with regard to privacy, underage gambling, and give you access to redress should the need arise.

Similarly, all of the mobile casinos listed here are operated out of jurisdictions with well regarded gambling authorities, such as the Malta Gaming Authority, the Guernsey Casino Gambling Control Commission, or the Alderney Gambling Control Commission. This means that you can be sure that games are being operated fairly and that there are policies in place with regard to how your private information is stored and used.

Furthermore, all of our featured mobile casino have their games independently audited and tested by third party specialists who certify the fairness of games and how they are operated, in particular the random number generators (RNGs). These agencies also publish the return to player percentages (RTP) of all categories of games, and make this information accessible to players. 


Mobile slot apps vs. websites

It is estimated that around 94% of all people in the UK own a smartphone, and according to the Office of National Statistics, 78% of adults use smartphones or other mobile devices to access the internet. Unsurprisingly, this has been accompanied by a significant increase in the amount of time players in the UK spend playing slots on mobile and other casino games. 

Slot developers and operators have responded to this by making huge improvements to the mobile slots gaming experience, and this platform is almost unrecognisable today compared to what it looked like just five years ago.

The biggest advantage to playing slots on mobile is, of course, the convenience and accessibility they provide, plus the fact that you can play a huge range of games anywhere when you are on the go. Being able to sync your account also means that you can switch seamlessly between playing platforms, with your account accessible on any device, including your laptop or desktop.

As evidence of the fact that mobile slots play is now more popular than other ways of playing, a number of operators are now offering what are called mobile-first sites, where the focus is much more on the mobile casino rather than the desktop site.

This means that the user interface (UI) of the best mobile casinos are specifically designed to make it as easy as possible to play on the smaller screens of phones and tablets, and as a consequence the overall gaming experience is actually better than if you play at the same site on a desktop or laptop.

HTML5 technology also means that games are web-based, and so there is no need to download or install an app or casino software, giving you the option to be able to play on any device (not just your own). This also means that storage on your device is not being taken up, slowing down your phone’s other essential functions.

Another way in which games development has changed in response to the increase in mobile slots play is that there has been a shift in emphasis away from slots with elaborate special features (featuring video clips and a separate game, for instance) to free spin bonus rounds. This means that bonus rounds are played more like base play, and so there is not as much battery drain or data usage required. If data usage is a concern, then the best solution is to find these sorts of games, where the special bonus rounds come in the form of free spins rather than the more complex types of additional rounds.

The best devices for playing mobile slots

As mobile slots are increasingly web-based, most modern mobile phones and tablets have the capacity to provide stable gameplay with full colour graphics and an array of sound effects. Provided you can connect to the internet, you will be able to play slots on mobile on just about any device from the leading phone producers.

Mobile phone design, too, has changed in response to the increase in mobile use and gaming, with the current trend being towards larger screens in order to maximise the mobile gaming experience.

Bearing all of this in mind, the following mobile phones will all offer players a first-rate gaming experience:

iPhone XS Max

This new smartphone from Apple has a 6.5 inch screen, with 2,688 x 1,242 resolution, that offers excellent gaming clarity.

OnePlus 6T

Featuring a 6.41 inch screen, this phone is also notable for offering long battery life, ideal for mobile gaming when you’re out and about.

Samsung Galaxy S9+

One of Samsung’s most popular devices, the Galaxy S9+ has a 6.2 inch infinity screen, with the full HD capability providing excellent visuals and special effects on all mobile slot games.

Google Pixel 3 XL

Able to present 16.77 million colours as well as true black, the 6.3 inch screen makes this an excellent smartphone for getting the most out of your mobile gaming experience.

Samsung Galaxy Note 9

With a 6.4 inch screen featuring 2960 x 1440 resolution, this is a lightweight phone that nevertheless delivers in terms of high quality gaming graphics.

What can I do if slots are lagging on my device?

The first step if a slots game is playing slowly on your mobile device is to ensure that all other apps are closed, as you may have apps open in the background that you are unaware of, and which are proving to be a drain on your processing power.

We would also suggest that you check you have the latest software downloaded and installed on your device, and that your browser is the latest version. Games are constantly being updated by their producers, so if you don’t have the latest software and browser, this could be what is causing a game to lag.

You should also check that you are playing using a wi-fi connection whenever possible, as this is likely to offer a smoother performance than a 5G or 4G connection.
