How We Review the Best Casino Slot Apps Online
As our slots experts at SlotSource.co.uk are passionate about mobile apps, we decided to combine our expertise and passions in putting for you a complete guide to the best casino slot apps and slot mobile sites. But our passion alone isn’t enough, so we invest into every slot app we review many hours of hard work in order to bring you the ins and outs, and recommend to you only the best casino slot apps and mobile slot sites in the UK.
Although when it comes to reviewing the best slot machine apps our work and play intertwine (did we say we are passionate about slots already? hence the reason why!), we still follow a rigours process that lets us bring you professional and objective conclusions. The following are factors we look at for every mobile slot app we review:
Slot App Gaming Licence
- Your safety should always be a top priority, especially when it involves your mobile device which contains a lot of personal and sensitive information. If you are playing the best slot apps for real money, your banking details must also be protected. Therefore all the slots apps and websites we recommend on SlotSource.co.uk are always licenced by the UKGC (UK Gambling Commission) and are therefore constantly subject to compliance checks and audits.
- Always use the best slot apps we feature on SlotSource.co.uk to be sure you are playing on casinos that are 100% legal in the UK!
Slot App Security and Data Protection
- Beyond the most basic requirement of a mobile slot app being legal and licensed, we also look at which of the best casino slot apps and websites take issues of privacy and safety even further and follow their own vigilant, strict privacy and data protection policies. Our team will check the apps encryption and security certificates, RNG (Random Number Generator) audits and everything else to make sure we only feature on our site the safest slot apps in the UK.
Slot App Trustworthiness
- The most reliable, objective reviews always come from casino players like yourself. We therefore speak to customers and scour the web for customer reviews and feedback on every mobile slot app we assess. We take every casino’s trustworthiness and reputation with players into account when writing our reviews and recommending you the best casino slot apps.
Mobile Device Compatibility
- A slot app, or mobile casino website will only be as good as the mobile devices it works on. We test every mobile slot app on different devices and operating systems to make sure it’s compatible. So regardless of you using a smartphone or tablet, and whether it’s based on an Android, iOS or Windows Phone operating system, our SlotSource.co.uk will always find the best casino slot app for you.
Slot App User Experience
- There are many factors in a slot app and mobile slot site that contribute to a great gameplay experience. When looking for the best casino slot apps to recommend, our experts examine closely the app design, user interface including menus, buttons and navigation, as well as app connectivity and overall performance.
Slots Available on Apps
- Although the majority of new online slots are available on the casino’s mobile-responsive client that is accessible through most mobile browsers, offering a slot game on an app takes a bit more development and effort. Therefore the selection of slot games varies greatly between apps. In search of the best casino slot apps in the UK, we always look for casino operators that invest the most effort into transferring games from their main casino client and making as many games available on their apps. So you can be sure that SlotSource.co.uk recommends the mobile slot apps that boast the biggest selection of slot machines.
App Slots Selection
- When it comes to the selection of games, the best casino slot apps must not only have quantity, but quality as well. Therefore our experts look carefully at the software providers that power each slot, the big hit slot titles available, progressive jackpot slots and more.
Mobile Targeted Bonuses and Promotions
- Online casino operators in the UK make extensive use of bonuses and promotions to entice new players to sign up, as well as reward loyal players and introduce them to new games, tournaments and features. Many of the casinos we recommend offer exclusive bonuses that targeted mobile slot app users. For example an exclusive bonus to players that install the casino slot app, no-deposit bonuses that can be played online on slot apps, etc.
- Bookmark our page so you never miss the latest free slot machine apps and all other generous bonuses and promotions that are customized for mobile app users.
App Banking Methods
- If you are looking for the best slot apps to win real money, it is important to have easy and safe ways to deposit funds and withdraw winnings. Therefore our team at SlotSource.co.uk will always check the app’s banking section to evaluate the variety of payment methods available. When recommending to you the best casino slot apps we also look at withdrawal limits and the time it takes to process withdrawals, transaction fees, currency exchange rates and overall usability of the slot app’s banking section.
Slot App User Customer Support
- Customer support is one of the most important parts of any casino experience, let alone for players that use slot apps and mobile slot websites. The best casino slot apps will have an extensive FAQ section as well as customer support channels such as live chat, email and phone support. All these factors are considered when we contact each casino’s customer support team and check helpfulness, response times, etc.
Not All Online Casinos Offer Mobile Apps - Why?
Surprisingly to some, not all online casinos offer slots apps. Instead, some casinos in the UK offer their players mobile casinos that are optimised for smartphones and tablets in addition to their main desktop client. Although operators will have their own reasons and priorities for choosing to offer a mobile site and not a casino app, there are two main reasons that drive casino operators in this case: providing their players greater choice and increased game accessibility.
Some online slots are extremely resource-heavy and that makes them unsuitable for mobile apps. For example, a game like Arabian Nights contains a selection of interactive bonus rounds and animations. Running this game via an app isn't easy because mobiles only have limited resources. To combat this, operators use a mobile casino site as the host. Basically, because mobile websites have more capacity for hosting resource-hungry slots, operators may choose to go down this route.
However many of the leading casinos in the UK will let you enjoy the best of all worlds: offering a desktop client, mobile slot browser client and a dedicated app – all which can be accessed seamlessly using the same casino account. Naturally, these operators will have the best casino slot apps as they are view their customers’ experience as one of their top priorities. Because of the variety of platforms and options, you will also tend to find on these casinos the best mobile slots.
Although iOS and Android devices are the dominant platforms in the mobile arena, they're not the only names in town. Because most online casinos only have limited resources, they often focus their attention on iOS and Android devices. However, to ensure that everyone gets access to the latest games, these operators will optimise their mobile websites to ensure Windows Mobile users can also enjoy playing the best slots.
What About Apps Dedicated to Slots?
In general, when you want to spin the reels of the best online slots using your mobile, you'll find the most popular games are usually offered on the best casino slot apps. Because the big slot machine titles make up such a large part of an operator's overall casino game offering, it makes sense for slot sites with apps to offer slots, casino table games, scratch cards, arcade games and all other games in one mobile casino app. However, there are still some operators that like to keep things separate. Although dedicated slots apps are less common than general casino apps, you can still find them. What's more, these dedicated slot game apps usually have the largest selection of big name titles in the business.
Top Slot Games to Play on Mobile Apps
Many of the biggest and best online slot games can now be played via apps and mobile casino sites. This increased access to action doesn’t only mean you will be able to play some of the most popular video slots, but also the UK’s leading progressive jackpot slots. Basically, whatever your preferences are in 2021, you'll find them on your mobile. Below are some of the best slot games our experts enjoyed playing on mobile sites and apps in the UK in 2021:
- Mega Moolah (Microgaming)
- Starburst (NetEnt)
- Rainbow Riches (Barcrest)

- African Legends (Microgaming)

We constantly update this section with new games, so check it out regularly to stay up to date with the latest mobile slot games.
Software Requirements for Slot Game Apps
Regardless of which mobile device you use, you should always have it updated with the latest version of the operating system to meet the software requirements of the newest, best casino slot apps. Although you can still enjoy a fairly sleek gaming experience with a system that is a bit older if you choose to play via a mobile website, apps really do need the latest software version to work efficiently. Indeed, as well as giving you the greatest scope to enjoy more games, graphics and betting options, meeting the minimum software requirements is necessary to ensure you have the latest security protocols in place. Assuming your device is up-to-date, the average slots app will be around 20mb in size, so make sure you have this memory spare for the download process.
Beyond the latest software updates, the newest mobile devices will always guarantee the best hardware, processing speed and graphics, resolution and sounds that will enable you to enjoy the slot apps to the fullest. Speaking about enjoying online slots graphics and resolution: Apple is soon going to release the iPhone 12 Pro which at 6.7 inches, will be the largest iPhone to date. If you are an Android user, you have a choice to play mobile slots apps with top of the line Samsung Galaxy S20 or S20 Plus, or opt for a niche phone like Sony Xperia 1 II which is considered very strong with visuals.
If you like to use your mobile slots app on a tablet, there’s the Samsung Galaxy Tab S7 which is considered a serious rival to the iPad Pro range, with a 12.4 inch screen and superior resolution that will make your slot reels jump out of the screen. Or if you are a Kindle user, the Amazon Fire 8 Plus HD isn’t a premium tablet, but with 3GB RAM you get a boost on the standard Fire 8 performance. So you can have a very good tablet for slot apps at a very reasonable price.
These are only a few of the newer devices we used to test the best casino slot apps and websites, but probably any newer tablet or smartphone will provide you with a great, exciting mobile slot experience.
Do Apps for Slots Sites Offer Casino Bonuses?
Yes of course they do! Mobile casino operators in the UK use bonuses extensively as a tool to advertise themselves to new players and encourage them to sign up, as well as reward existing players for their loyalty. Moreover, casinos use bonuses to introduce to their players new slots and other casino games and entice them to try new games, features and platforms. The following are of the common types of bonuses offered on the best free slots apps in the UK:
Slot App Welcome Bonuses
As their name suggests, these bonuses are offered to welcome new players that are registering to the casino’s slot app or website. As welcome bonuses are available only to new slot apps players, they can only be used once. The best casino slot apps use different types of bonuses in their welcome offer including no deposit bonuses, deposit bonuses, free spins and more.
No Deposit Bonuses
No deposit bonuses, also known as sign up bonuses are given to new players simply for downloading and installing the slots app and signing up to the casino. As the name suggests, you will not need to make a deposit in order to claim this type of bonus, so you can use it to play on the best free slot machine apps.
A deposit bonus is given to players that deposited funds in their casino account and are ready to play on the best slot apps to win money. Usually the casino will match up the amount deposited with bonus money at a certain percentage. For example a 100% deposit match means that if you deposit £100, the casino will add £100 in bonus money to your slot app account, giving you a total of £200 to play with.
A free spins bonus is given as a set number of times you can spin the reels of a slot machine without spending any of your own money on the wagers. Free spins are usually given by the best free slot apps as a way to introduce players to new slot games. Therefore this bonus is typically restricted to one, or a handful of slots that are eligible to be played as part of the free spins offer.
The best casino slot apps and sites that we recommend on SlotSource.co.uk offer reward programs that let you collect loyalty points for wagers you place on slots and other casino games. Points can then be redeemed to claim bonuses, cashbacks and other benefits.
Refer a Friend Bonus
Many of the best casino slot apps in the UK will offer you a special bonus for simply referring a friend. Some casinos even take it a step further and give a bonus to your friend on your behalf as well.
Mobile Exclusive Bonuses
The leading online casinos in the UK invest significant resources and efforts into staying ahead of the mobile curve. In addition to mobile app innovation and introduction of more games on mobile apps, operators also invest in bonuses that are exclusive to mobile casino and slot apps users. These bonuses would usually include free spins, loyalty points and other bonuses given simply for using the casino’s slot app or mobile slot website.
Bonus Wagering Requirements
It is important to understand that more often than not, bonuses come with wagering requirements, which define the times required to wager the bonus before it can be redeemed into cash and withdrawn. It is always recommended to check the casino slot app’s Terms & Conditions for wagering requirements and other bonus rules.
Top Rated Slot Game Apps for iPhones
As we’ve noted above, Apple’s iOS is one of the most popular mobile platforms in the world which means that all the leading slot games have been made available for iPhones and iPads. As you scroll through the Apple app Store, you'll see iPhone and iPad free slot apps as well as iPhone and iPad free casino apps offering instant access to the best slot games in the UK.

This means that you should be able to enjoy the most popular games available. For easy access to the best Android slot games in 2021, British players should check out these mobile apps:

FAQ: Best Slot Apps
Do I need a separate account for a slot app?
Online casino accounts are generally based on your email address and username rather than the device that you use, so you do not need a separate account to play via a slot app. If you have already created a casino account, you can use the same username and password for the casino's slots app. You will be able to log in and immediately view your account balance and settings.
Can I access progressive jackpot slots via casino apps?
Casino operators often feature their best, most admired slot games on their slots apps. This of course includes many of the UK’s most popular progressive jackpot slots. In addition, most casino apps in the UK also offer on their app the same slots tournaments and live dealer games that are available on their main desktop site.
Are slots apps "lite" versions of the main casino sites?
There are different kinds of slot apps. Some apps are simply mobile-optimised versions of the main site, which adapt to the size of your screen and can be accessed through your browser. Downloadable apps could be a specifically designed app (which may have fewer games than the main site) or they could be an access portal to the full site. Depending on the casino app, you may get a "lite" version, but in most cases, you will get the full functionality of the main site in a mobile-friendly format.
Can I deposit directly via a slot app?
Yes you can. Slots apps offer a wide range of deposit methods which let you deposit directly through the app’s banking section. There are even deposit methods that are exclusive to mobile app users and allow you to deposit through your phone bill.
Is the mobile slots app experience better than tablet one?
It will depend on your own preferences. Some slots app users like the bigger screen size of tablets, whilst others prefer the small and compact phone screens. The app is optimized for every device so the experience is great in both cases.
