Comprehensive Guide to the UK’s Best Slot Bonuses in September 2021

So, you’re on the hunt for the best slots bonus UK casinos can muster? You’ve come to the right place. This detailed guide not only reveals some of the best slots sign up offers, but also outlines the different kinds of bonuses, and explains how we decide which deals deserve to be in the spotlight. Let’s dive in.

How to Claim Your Slot Bonus

If you're wondering how to claim that online slot bonus, just follow these simple steps:

Compare Online Casinos
The first step is finding the right online casino site for you. There’s no need to feel daunted by all the options, as we’ve handpicked some of the best right here. You can compare the different slots welcome bonus deals at a glance, or delve into our detailed reviews for more information on all aspects of the sites – from the size of their games libraries to the banking methods they accept.
Read the Terms and Conditions
Before getting too excited at what slots bonuses UK casinos might have on offer, it’s important to check the T&Cs. These will tell you if you need to pay a minimum deposit to unlock the bonus, and what the wagering requirements are. You’ll also see which games can be played with the slot bonus, and how long you’ve got before the bonus expires.
Click through to the casino and sign up
Chosen your casino? Just follow our link to the sign up page. Here, you'll need to enter some personal information and set up your username and password. If there’s a no deposit slot bonus on offer, you’ll probably access it at this point.
Make a deposit or play with your slot bonus
If you've chosen a site with a slot bonus that requires a deposit, you'll have to transfer some of your own money into your new casino account before you can claim the deal. It should be a very simple process: head to the cashier page of your account, choose the deposit method that suits you, enter the amount you want to play with, and the transfer should be made in no time.

Types of Slot Bonuses

When seeking out the best slot bonus UK casinos can offer, it pays to know what’s what. Let’s take a look at some of the most widespread online slot deals you’ll see at UK casino sites.

Slot Welcome Offers

Slot welcome offers are available to those signing up to a new betting account at a casino. The key thing to know is that these can’t be claimed by existing customers. Instead, they’re an incentive designed to attract new players, and you’ll see some of the best slots welcome bonus offers on this page.

100% Matched Deposit Slot Bonus

With a matched deposit bonus, the casino will give you a percentage of your deposit in bonus funds that can be uses on slots or other eligible games. If it’s a 100% matched deposit, the house will double your initial bankroll – so, if you were to deposit £20, you’d be given another £20 in bonus funds. Bear in mind there’ll be an upper cap on this, so a typical deal might be ‘100% up to £300’. Always check what the wagering requirements and time limits are.

200% Matched Deposit Slot Bonus

A 200% matched deposit bonus works in just the same way as a 100% matched deposit bonus, only it’s twice as generous. So, pay £10 into your account, and you’ll end up with £30 in your bankroll. That is to say, £10 of your own money, and £20 in bonus funds. Again, there will be a minimum deposit and a maximum cap, so make sure you check the small print.

500% Matched Deposit Slot Bonus

Even bigger than the 200% matched deposit bonus, the 500% matched deposit slot bonus is among the most generous offers out there. It means the casino will give you five times your deposit in bonus funds. As this is a huge percentage, there are often tighter maximum limits in place, and the wagering requirements may be pretty steep. As ever, check that small print.

Free Spin Bonuses

When players think of online slot deals, free spins will probably be the first thing to spring to mind. These are exactly what they sound like, letting players spin the reels of selected games without spending any of their account balance. A set number of free spins are commonly given to new customers as a sign up bonus, often alongside a matched deposit bonus. If wagering requirements are included, these will apply to anything won using the free spins, so you’ll want to double check that before you head for the slots.

No Deposit Slot Bonus

A no deposit slot bonus is any slot bonus that doesn’t require you to add money into your betting account. For example, you may be given 50 free spins just for signing up to a site. While this can certainly be an appealing prospect, there will certainly be a string of terms attached.

Reload Slot Bonuses

Reload slot bonuses are offers aimed at a casino’s existing customers, rewarding loyalty and making it worth their while to come back for more. Reload slot bonuses often take the form of batches of free spins, awarded daily or weekly to those who’ve deposited or bet a certain amount in the past week.

The Top 5 Slot Bonus Sites

Wondering where to get started with online slots? Our experts have recommended five of the top sites for fans of the reels.

Vegas Spins

More than 600 individual slot games await at Vegas Spins, and there’s a welcome bonus tailor-made for slot lovers. On making a minimum deposit of £10, new customers can spin the special Welcome Wheel with the potential to land a whopping 777 free spins. The site itself is easy on the eye, with the library of slot games clearly laid out, and top branded slots like Narcos, Game of Thrones, and many more on offer.

Jackpot Village

Jackpot Village has made its name as one of the leading purveyors of live casino gaming in the UK. It especially excels in the realm of slots, with more than 1,200 available, including a solid range of progressive jackpot slots with ever-escalating prize pots. You can get things off to a great start with the welcome bonus, which features a matched deposit of 100% up to £500 along with 50 free spins to use on Book of Dead.

Casumo

There are 2,000 – count ‘em, 2,000 – slot games at Casumo. That fact alone should automatically put this site on any slot fan’s radar. There’s also a nice welcome bonus package which includes 25 free spins on Book of Dead and 100% matched deposit up to £25. Casumo also offers its members a really well-designed casino app and a good loyalty scheme.

Novibet

Players can claim a welcome matched deposit of 100% up to £150 at Novibet along with 15 free spins on Book of Dead. But that’s just the start. The site itself is truly vast, with close to 4,000 slots available. If that sounds mind-boggling, don’t worry – Novibet has helpfully broken the slots down into all kinds of categories, from Irish-themed to Egyptian-themed to even summer-themed, so you can soon find the right slots for you.

Race Casino

Race Casino is a great pick for anyone after something a bit different, thanks to its unique motor racing theme. The selection of slots is bound to get any player’s engine revving, with over 1,200 titles including plenty of Megaways games – those are the ones with the shape-shifting reels and more chances to come up with paylines. While the welcome bonus doesn’t include free spins, players can use the 100% up to £100 matched deposit funds on the slots of their choice.

Bonus Calculator

Our bonus calculator tool makes it easy to find out the amount you’ll need to wager in order to meet your bonus’s wagering requirements. Enter the deposit value and percentage, the wagering requirements, the contribution percentage of your favourite game, and whether your casino includes your deposit in the calculation. All of the details you’ll need can be found in your casino’s bonus terms and conditions. Once that’s done, click ‘Calculate’!

Best Payment Methods for Claiming a Slot Bonus

You’ll need to make a first deposit to access the majority of online slot bonus deals. Here are some of the payment methods supported at many of the top UK casino sites.

Debit Cards

Using your debit card to play casino games works the same way as shopping online. You just fire up the cashier page, enter your card details and send the funds over. Debit cards are accepted at just about every online casino, and making a first deposit this way means you’ll be eligible for any slots welcome bonus deal on offer.

Bank Transfer

Bank transfers are an old school way to put money into a betting account. While a bank transfer may take longer to process than a debit card transaction, it’s a good method for high rollers as casinos tend to have higher deposit and withdrawal limits for this option. As with debit cards, this is a universally accepted method across UK slot sites.

e-Wallets

e-Wallets like PayPal, Skrill and Neteller bring certain advantages. You won’t have to share your bank or debit card details when making a deposit, which is a major plus point for security-conscious players. Withdrawals also tend to be faster with e-wallets. The one potential snag is that some online slot deals can’t be accessed if you make your first deposit through certain e-Wallets, so check the T&Cs.

Prepaid Cards

Using a prepaid card system like Paysafecard is simple: just buy a voucher online or in a shop, then transfer the voucher’s value over to your casino account using a PIN. It’s super-secure – effectively like using cash online – but it’s important to check you’ll be eligible for slots welcome deals if you pay this way. Withdrawals generally won’t be possible with Paysafecard.

Pay by Phone Bill

Services like Boku now let players pay casino deposits using their mobile phone bill. The process is pretty straightforward: input how much you’d like to deposit, type in your phone number, and then confirm the transaction. You’ll get the cash into your betting account and the amount will be added to your next phone bill. Again, Boku and phone deposits might not unlock some slots bonuses, and they also can’t be used as a withdrawal method.

Frequently Asked Questions

  • Not always. With no deposit bonuses, you won’t need to pay a penny into your account to claim the bonus funds or spins. However, these will usually come with wagering requirements and other conditions.

  • Some of the top slots bonuses UK casinos have on the table include free spins on Book of Dead and Starburst. Some sites will even give you a wide range of slots you can use your bonus on – for example, all NetEnt slot games in their library.

  • Almost certainly not. Slot bonuses are like any other casino bonus, meaning they come with T&Cs attached. The small print usually dictates that you have to fulfil a wagering requirement before you can withdraw any funds associated with the bonus offer.

  • That all depends on the casino. Welcome bonus packages often include free spins as well as a matched deposit, which can both be claimed at the same time. In other cases, you’ll only be able to claim one bonus at a time.
