4 Mobile Slots Bonuses You Can Take Advantage Of

If you’d like to play mobile slots real money but still want to benefit from that something extra, why not have a look at our recommended casino bonuses? We go through the types of mobile offers you can get as a new and returning player below.

  • Welcome Bonuses

    You’ll usually get welcome bonuses in the form of a package. The most common ones include a match bonus and free spins. This means that the online casino will match your deposit up to a certain amount, and will let you spin a couple of times on a series of popular mobile slot games.

    Did you know? You can always opt out of receiving a welcome bonus, for example, if you feel that the playthrough requirements are too high for you to fulfil.

  • Mobile Slots No Deposit Bonuses

    If you’re looking to test a new mobile slots casino but don’t want to risk your own cash, then a no deposit bonus is the right fit for you. Once you claim the offer, you’ll get extra money from the casino, which you can use to check out the game lobby.

    If you lose on any of the no deposit mobile slots, you won’t have lost your own cash! But if you do win, you will have to deposit to withdraw any winnings from the bonus.

  • Mobile Slots Free Spins

    Claiming mobile slots free spins bonus allows you to try different games for a small deposit, or no deposit. Free spins are mostly given to compliment a match bonus, where you’ll be able to play your spins over a period of time. On the other hand, you won’t need to use your own money to claim free spins no deposit, but you’ll have to deposit to cash out any winnings from the free spins.

  • Mobile-Exclusive Bonuses

    WWhile mobile-specific offers aren’t the most common, the best UK slot apps reward players for downloading the casino app to their phone. In return, you’ll usually get bonuses such as free spins.

Pay by Mobile Slots Explained

Spinning on real money slots mobile has never been easier. You can now use your mobile phone balance to deposit funds into your casino or app account!

Pay by mobile slots bring plenty of benefits. You don’t need to provide any card details to the casino, which makes transactions both quicker and safer. And the same goes for bank details – you’ll only need to input your phone number.

There are also quite a few pay by mobile providers out there, so you’ll have quite the choice. Some of the best ones include Boku, Zimpler, and Payforit. Boku is available for players worldwide, whereas Payforit and Zimpler are more popular in the UK. You can also make use of Zimpler if you’re based in Sweden or Finland.

So, how does it all work?

First off, you’ll need to find your favourite pay by phone casino and sign in. Then, head over the Deposits page and select a pay by mobile option from the list. Enter your deposit amount and you’ll be prompted to input your phone number. Authenticate the transaction through the confirmation code sent through your phone, and you’re all done! You can now play your top pay by mobile slots UK, while the deposit amount will be reduced from your phone credit.

Just keep in mind that you won’t be able to withdraw through pay by phone methods. Also, the maximum amount you can deposit per day is usually capped at £30.

Top tip: If pay by phone sites aren’t your thing when it comes to playing mobile slots, try e-wallets instead. Trustly casino sites are quick with processing deposits, and also mobile friendly.

The Most Popular Devices for UK Mobile Slots

When it comes to new online slots, it doesn’t really matter what mobile device you’re using. Whether you opt for Android or iOS, a smartphone or tablet, it’s really a matter of preference.

This is how most UK players are accessing the best mobile casino slots in 2025:

Mobile Slot Casinos vs. Mobile Slot Apps: How to Make Your Choice

What’s the difference between playing on your mobile in-browser and a mobile slots app? You can access a mobile casino instantly while you’d need to download a mobile gambling app directly to your phone to play slots on the go.

Some mobile slot casinos will also have their own dedicated app that you might prefer to play from. If you opt for installing an app to play mobile slot games, you should first find a trusted UK casino that offers it. Beware scam apps made by unknown developers that can trick you into giving them your money and personal information.

When you play on a real money slots app at one of our best slot sites in the UK, you’ll be safe and have a great time playing. You’ll enjoy games by leading software providers, and even claim a mobile welcome bonus in most cases.
