Mobile slots: your guide to playing on-the-go

What are mobile slots?

Mobile slots are online slot machines optimised for mobile devices, such as smartphones and tablets. These slots have large buttons and stripped-back designs to make them easy to play on a small touchscreen. Also known as touch reels, mobile slots avoid using flash effects that don’t work on iPhones and iPads.

With mobile gambling accounting for over 20% of all online bets and forecast to grow at speed, it’s not surprising that casinos are investing in on-the-go gaming. Online casinos know that mobile slots will soon be as popular as desktop games, which makes offering slots compatible with mobiles a priority.

Benefits of playing slots on your phone

  • Flexibility: Play anywhere you like rather than sticking to the one room
  • Bonuses: Try out different bonuses that aren’t available to desktop players
  • Multi-task: Pause a game halfway through to answer a text or take a call
  • Instant play: Launch mobile slots straight from your browser
  • Accessibility: Securely login and play when on trips away

Here, we’ll explain in detail exactly how mobile slots work. We’ll also answer some common questions players ask about playing slots on portable devices.

How long have mobile slots been around?

Mobile slots first launched in 2007. Their arrival came shortly after the release of Apple’s original iPhone, which included the touchscreen technology that would transform mobile gaming.

Once touchscreens became a thing, it was only a matter of time before slots responding to your touch came about. Remember the likes of mFortune Casino? If you’re under 25, you probably won’t. But mFortune was one of the first casinos to bring out mobile slots, and you could only access the website via your phone. If you were a mobile gambler in 2007, mFortune was the place to play.

More recently, mobile slots have become commonplace. There’s no longer a divide between mobile casinos and regular web-based casinos – most online platforms have a selection of mobile games. That said, some casinos ‘do mobile’ far better than others, so make sure you check out the best places to play mobile slots.

How do mobile slots work?

Mobile slots, like standard slots, spin reels of symbols to produce winning combinations. The reels cover most of your screen, but there’s a section at the bottom to track your bets and winnings.

Some players access mobile slots through their favourite casino’s app. Casino apps are fast to download and launch but sometimes restrict cash bets. Cash bets are restricted because Google and Apple don’t like gambling apps appearing in their app stores, so regulate their use.

Although the restriction of cash bets is more common outside of the UK, make sure to double-check a mobile slots app’s terms of use. You don’t want to get all pumped up to play for real money only to realise the app doesn’t accept cash deposits.

Of course, if the app is a dud, you can still visit the mobile version of the casino’s website. You’ll do this via your phone’s web browser. Nowadays, most sites are intelligent enough to know you’re on your mobile and automatically scale down to fit your device’s screen.

Apps for playing mobile slots in the UK

You’ll find new casinos tend to focus on optimising their sites for mobile rather than developing a separate app. However, if you prefer the convenience of having an app ready and waiting on your phone, these apps are worth a try:

Mr Green App

Mr Green's app has 500+ mobile games plus slot tournaments with huge prizes.

Casino Room App

A great mobile slots app if you enjoy progressive jackpots like Mega Moolah.

Casino Cruise App

For those who like variety, the Casino Cruise app has table and live casino games too.

Will all mobile slots work on my phone or tablet?   

It shouldn’t matter whether you have an Apple or Android device – developers will test their slot games on both. Also, mobile slot games don’t drain a lot of power (unlike VR games for instance), so your phone doesn’t need to be top-of-the-range either.

The main thing is to make sure you’re playing the mobile version of the slot game. If you find that a game won’t open on your device, it’s probably because it’s trying to use flash effects not supported by your mobile or tablet.

Making payments for mobile slots

Most players place bets using their credit card or digital wallet. However, some casinos also offer the option to link payment to your phone bill. It is a handy way to group payments together, as you pay for your mobile and slots play in one sum.

Casinos accepting slot deposits via mobile phone credit

Many online casinos offering mobile slots accept payment via mobile deposits. Usually, the casino asks you to submit your phone number and confirm payment by responding to a text message.

If you’re a pay-as-you-go customer, the money will be taken straight from your phone credit. Meanwhile, pay monthly customers will see the charge added to their direct debit.

How to play mobile slot games

Mobile slot games work in the same way as the online slots you play on your desktop. But unlike some slots for desktop, mobile slots rarely have more than five reels so they can fit onto your phone’s screen.

You sometimes find mobile slot games include more bonus features to break up the monotony of spinning time after time. Most likely, game developers add these extra features because they know it’s easier to get bored and distracted when watching a smaller screen.

You trigger the bonus features by landing a pre-determined combination of symbols. Once the features are activated, you often have the chance to progress to the next level of the game and/or multiply your winnings.

As with normal slots, you’ll want to be on the lookout for the following symbols when playing on your mobile:

Wild symbols: A wild, or wildcard symbol, will take the place of a winning symbol if none appears. Wilds, therefore, increase your chances of landing a winning line, so always familiarise yourself with a game’s wild symbol before you play.

Scatter symbols: Scatter symbols trigger bonus features. They don’t need to land on the same line to work (hence they’re known as ‘scatters’).

Moreover, don’t think you’re excluded from getting free spins just because you’re playing on your mobile. Plenty of casinos offer mobile players excellent free spins deals, so make sure you make the most of them.

Top 5 mobile slot games and where to play them

Reel Rush – Trada Casino

Reel Rush is a favourite with slots players because instead of fixed paylines, there’s a range of combinations that give you money back. In fact, there are 3,125 ways to win playing Reel Rush, which is why the game has a high return to player (RTP) of 97%.

Reel Rush is a simple five-reel slot that easily translates to mobile devices. The maximum prize is £90,000, which makes collecting those winning combos all the more exciting.

Mobile Slot Scruffy Duck

Scruffy Duck – Leo Vegas

Scruffy Duck has brilliant bonus features including expanding wilds and free spins. You can’t help but smile at the wacky duck symbols covering the reels, which make the game super fun.

If you want to win big, you’ll need to activate the game’s multiplier features, which launch extra spins. But even if you don’t, you’ll enjoy the game’s quirky humour.

Secrets of Atlantis – Mr Green

Transport yourself to the underwater metropolis of Atlantis in this five-reel, four-row mobile slot. Secrets of Atlantis is a win both ways game (it pays left-to-right and right-to-left), which improves your chances of coming out quids in.

There’s the potential to win back x1600 your stake in this game, although most wins will come in at around x20 what you bet.

Starburst – Dunder

One look at the Starburst paytable will tell you this game offers lucrative wins. On top of the decent odds, you also have an entrancing theme with graphics of stars accompanied by cosmic tunes.

The game also works well as a mobile slot with the 10 paylines sitting neatly alongside the reels.

Age of the Gods – Slots Heaven

If you enjoy a progressive jackpot, Age of the Gods is a great choice. A successful run on the jackpot game could win you thousands.

Try to get hold of a free spins offer on this mobile slot, as it’ll supercharge your gameplay.

Can you win big playing mobile slots?

The return to player rate (RTP) on mobile slots is usually the same as their desktop version. Always make sure to check before you play, just to be sure.

Also, just like with regular online slots, you’ll have a mixture of low and high variance games. So, depending on how lucky you’re feeling, you’ll have a range of options to suit your mood.

For the adrenaline junkies, progressive jackpots are just as prevalent on mobile as they are on a desktop. Back in 2013, one lucky woman became the first mobile slots player to win a progressive jackpot, raking in $1 million NZ on Mega Moolah. While earlier this year, a UK player won £1.36 million on the Gladiator progressive jackpot.
