My Top Sites with Slot Bonuses

Most online casinos have some sort of welcome offer. However, if it’s just online slot games you’re interested in, then you can find specific slot welcome offers.

Here at akfxoqsd.shop it's our business to find the best slot sites in the UK with the best promotions. And what's more, every casino we feature is licensed by a reputable gambling regulator, so you know they’re legit.

Below are some of my favourite sites for the best slots bonuses in the UK:

Best Overall Slot Bonus: Crystal Slots

  • Features: spin the Mega Reel to claim up to 500 free spins on the slot game Sweet Bonanza when you sign up and deposit £10.
  • Wagering requirements: x65
  • Need to know: when you sign up at Crystal Slots and deposit at least £10, you get to spin the Mega Reel, with potential prizes including Amazon vouchers, and 500 free spins on Sweet Bonanza. Then, after every deposit of £20 or more, you get another spin of the Mega Reel.
  • Our view: a bunch of 500 free spins is a great way to get into the swing of things and get to know the casino better. And while the wagering requirements to withdraw your bonus funds as cash are high, it's cool that you can spin the Mega Reel after every £20 deposit.
Crystal Slots Bonus Deposit £10, Get up to 500 Bonus Spins on Sweet Bonanza
#ad. 18+. Gamble Responsibly. GambleAware.org. New Customers Only. T&Cs apply. £10 min fund, Free spins won via mega reel, 65x bonus wagering requirements, max bonus conversion to real funds equal to lifetime deposits (up to £250).

Best Free Spins Slot Bonus: NetBet

  • Features: a 500 free spins slots sign up bonus when you use the code NBWELCOME500 and deposit £10. 
  • Wagering requirements: any winnings with the free spins are converted into bonus money and this must be wagered 40 times before you can withdraw any cash.
  • Need to know: you get 50 free spins as soon as you make your first qualifying deposit and then you get the remaining 450 free spins in batches of up to 75 spins within six days. Skrill, Neteller and prepaid card payment options are not included in this slots welcome bonus in the UK. 
  • Our view: this is a healthy chunk of free spins to start enjoying slots online, and we appreciate the relatively low first deposit amount needed. 
NetBet Bonus Up To 500 Bonus Spins Promo Code: NBWELCOME500
#ad. 18+. Gamble Responsibly. GambleAware.org. New Customers Only. T&Cs apply. £10+ deposit, no e-wallets/prepaid cards, up to 500 Free Spins, 40x wagering on Free Spins winnings, £5 max bonus stake.

Best Cashback Slot Bonus: No Bonus Casino

  • Features: 10% cashback on your deposits when you lose all the money you deposited in a single day, forever.
  • Wagering requirements: no wagering necessary.
  • Need to know: the cashback bonus is available for 10 days after you made the associated deposit. Your balance must be below £10 to activate a cashback withdrawal.
  • Our view: we like No Bonus Casino's cashback deal, because it softens the blow of losing bets. What's more, the fact you don't need to wager the bonus makes it very straightforward. We also like how this slot bonus is so different to 99% of others out there. It also means you can get something out of best payout online slots, which are often excluded with other promos. 
No Bonus Bonus Always 10% Casino Cashback
#ad. 18+. Gamble Responsibly. GambleAware.org. New Customers Only. T&Cs apply. 10% Cash back without wagering the day after if the player loses all the money in the account. Min deposit £10. Gameplay is monitored.

Best Weekly Slot Bonuses: LeoVegas

  • Features: 30 10p free spins on Big Bass Bonanza every Thursday and 10 20p free spins on Rich Wilde and the Book of Dead every Monday.
  • Wagering requirements: 4 x wagering on casino games for the Thursday free spins and 3 x wagering on casino games for the Monday free spins. 
  • Need to know: to get the Thursday free spins on Big Bass Bonanza, log in and get your offer card between 09:00 and 23:59, before making your deposit of at least £25. For the weekly free spins on Book of Dead, log in between Monday at 09:00 and Wednesday at 23:59, get your offer card, and deposit at least £25. You can also get slots deposit bonuses on new and promoted games like 25 free spins worth up to €1 each on The Bounty Hunter Unchained.
  • Our view: LeoVegas has great slots bonuses, including these two weekly offers, and even if these deals are eventually removed, we can imagine them being replaced by other cool bonuses. Book of Dead is one of the most common casino video slots included in slots deposit bonuses, however, giving players free spins every week is pretty rare.
LeoVegas Bonus Welcome Package up to £200 + 100 Bonus Spins
#ad. 18+. Gamble Responsibly. GambleAware.org. New Customers Only. T&Cs apply. Opt in & deposit £10+ in 7 days & wager 1x in 7 days on any eligible casino game (excluding live casino and table games) for 50 Free Spins. Wagering contributions vary.

How to Find the Best Slot Bonuses in 2024

Slots are the most played games at casino sites, so it's no surprise many operators try to attract you with an online casino bonus on slots.

There's one obvious reason why slots are so popular. If you're lucky, you can win big jackpots from modest stakes. For instance, a UK player won £16 million from just 25p! This kind of jackpot size and win is rare though — there's perhaps a one in 34 million chance of winning a £16 million slot jackpot. 

Another big attraction to slots is bonuses. You can get a 100% match bonus to sign up at a casino, and existing players can also grab a slots deposit bonus.

We aim to bring you all the top slots bonuses on brand new online slots in the UK. The market is constantly changing, so instead of testing hundreds of casinos yourself, we do that for you.

Finding the Deals: Online Slots Bonus Offers

When seeking the best offers, most of our time is spent within the T&Cs of slots bonuses. It’s only once we’ve studied these that we can assess if a bonus is worth promoting.

We want to make sure you get the right slots bonuses for the games you want to play, but we won’t push a site based on reputation alone.

Some casinos make you work harder than others to unlock your bonus, and we’ll let you know which offer the best value for the time and effort required.

How to Sign Up for the Best Slots Bonuses in the UK

  1. Choose a casino ✅ | Select from our list above and see which one offers the best slot bonus UK players can claim. Note that free spins bonuses let you play a few free online slots and find a game you love.
  2. Open an account 📝 | To play online bonus slots, players first need to create an account with that casino site.
  3. Check the terms and conditions 📄 | Although most bonuses come with similar terms, it makes sense to check them before making a deposit.
  4. Activate an online slots bonus 🎁 | Some bonuses, such as no deposit bonuses or free spins, can be activated simply by opening a new account. Some require a promo code – if you’re unsure, contact customer support for help.
  5. Make a deposit 💰 | Most of the biggest bonuses require money to be paid into your account before your bonus can be used. Minimum deposits are usually at least £10 but often £20. Remember, many e-wallets are excluded from claiming bonuses, but you can still find PayPal casinos online that will give you a bonus.
  6. Start spinning! 🎰 | Once you have your bonus, start using it to play slots! If you win using bonus spins or credit and have fulfilled the wagering requirements, you’ll be able to withdraw your funds or keep betting.

Types of Slot Bonuses in the UK

Online casinos are ever-changing and bonuses evolve too. Any two offers are rarely the same, but plenty have a similar theme. Below, we highlight a range of bonuses that you can access at several online casinos.

UK Slots Sign Up Bonus

These bonuses welcome new players to the casino. The welcome bonus is the most common type of bonus that you can get as it’s part of a casino’s strategy to get you to sign up.

Free Spins Bonuses

Free spins are a nice taste of the casino’s slots section, allowing you to get to know the casino and perhaps win cash too. You can get these offers on their own or with another offer, like a matched deposit bonus.

The number of casino free spins you get will vary but the winnings will usually need to be wagered before you can withdraw any real money. This means betting the value of the bonus one or more times. These bonuses could also be called bonus spins, extra spins, and super spins.

The following free spins offers may interest you: 

Deposit £10, Get £40 in Bingo Bonuses + 200 Bonus Spins
Free Spins 110

Slots Deposit Bonus

The deposit bonus, or a matched deposit bonus, is very common. This is where the casino site will match the amount that you deposit up to a certain amount, e.g. you get a 100% bonus up to £100.

The value of offers like this vary depending on if you’re a new customer or a returning one. The bigger offers are usually reserved for attracting newbies, however, existing players can also claim offers like reload bonuses.

No Deposit Bonus

These are as rare as hens’ teeth these days, but if you’re lucky, you can still grab the odd no deposit bonus for slots. As the name would suggest, this is a bonus that the casino will give you for simply registering an account, with no deposit needed to trigger the bonus.

A bonus which requires no deposit could be free spins, or on a sports betting site, a free bet. Then, you’ll have to wager whatever you win with the bonus. No deposit bonuses are on the rarer side these days, but for slots, we have seen 25 free spins no deposit casino bonuses. Of those I've seen recently, I know that 888casino has a free spins offer where you get 10 spins on slot game Holy Mackerel Extreme Fishing every month for no deposit and no wagering. As 888 say, 'You keep what you catch'.

New Slot Promo Offers

Some casinos promote special offers when new slot games are released. It gives players the chance to play real money slots for free.

The offers vary, but they typically include prizes like extra spins, tech gadgets, holidays, cars, and entry into lucrative slots tournaments.

Reload Bonuses

These offers are for existing players once they have made their initial deposit and usually claimed the welcome offer that goes along with this. Casinos will offer a bonus on a player's 2nd, 3rd, 4th and even up to 5th deposit at that casino.

Cashback

A cashback offer is where the casino site refunds a percentage of your losing bets or deposit from a certain day, weekend, week or month. You might need to hunt for these but they can be found, especially at newer casinos that might work harder to keep you.

Loyalty/VIP Bonuses

Many online casino sites have loyalty programmes with lucrative prizes up for grabs like holidays and cars.

A good loyalty programme will allow you to earn loyalty points whenever you bet. The more games you play, the more points you earn.

With loyalty points, you can progress to the next member level, which can give you reduced wagering contributions on bonuses, a personal account manager, and more cashback every week.

Mobile Slot Bonuses

The success and accessibility of mobile casinos in the UK and the similarity between mobile apps and desktop casinos means that mobile-only offers are now rare.

That being said, it’s worth noting most casinos allow you to clear a bonus by betting on mobile via your browser or their app, on Android or iOS. The only issue is that not all games on desktop are also available on mobile just yet.

Many casino sites have produced casino apps where you can play for real money, so they are worth downloading if you want to play away from home.

Bonus Buy Slots

Who doesn't love slots bonus rounds? Bonus buys slots give you the opportunity to pay in order to trigger bonus rounds in certain slot games. Unfortunately this cannot be done in the UK anymore, after the UK Gambling commission banned this featured in 2019. We introduce you to alternatives that you can play and enjoy in the UK. 

What is a No Wagering Slots Welcome Bonus?

They're hard to find but you can get no wagering slots welcome bonuses. For example, when you join a casino you might get a deposit bonus of extra spins or even cash after your first deposit. Then you get to use that bonus to hopefully win more money. 

With this bonus type, if you win more cash, you can withdraw it without having to play through it 20 or more times.

Currently, one of the best slots welcome bonuses with no wagering is Kwiff Casino's 200 no wagering free spins bonus. You just have to sign up, make your first deposit, wager at least £20 on slots, and then you'll get 40 extra spins on the slot Rich Wilde and the Book of Dead. Whatever you win with those spins, up to £250, you get to keep. What's great is you get 40 extra spins every time you bet £20 on slots during your first five days as a member.

What's more, MagicRed has another slots welcome bonus with no wagering required, where you get a 100% up to £100 match deposit bonus plus 20 extra spins. And there's no wagering on any wins you make with those extra spins. Get that offer below:

Winnings won with bonus spins that require a deposit have no wagering requirements. The match-up bonus that requires a deposit must be wagered 40x.

Deposit Bonus Slots

Some slot games like Rich Wilde and the Book of Dead and Big Bass Bonanza feature in lots of slots deposit bonuses. There's no single reason for this but these are factors:

  • These slots are famous and their names attract new bettors
  • These slots usually have an average RTP and some are highly volatile, which means on average, players won't win a fortune from the bonus, which protects the casino from huge losses. Progressive jackpot slots are usually excluded from slots bonuses for this reason.

Popular Deposit Bonus Slots

These are some of the slots we usually see in slot welcome offers and existing players rewards:

  • Rich Wilde and the Book of Dead
  • Big Bass Bonanza
  • Starburst
  • Fishin' Frenzy
  • Big Irish Bucks
  • Eye of Horus

All these slots have an RTP around 96% or lower, which means for every £100 bet, the average player will get £96 back. Of course, you can win much more than 96% or lose more than 4%. Your maximum win potential also depends on any bonus limits. It's important to remember free spins and other deposit bonuses are simply that though—bonuses—so it's best to treat them as a nice added extra.

With thousands of slot games to choose from, it can be difficult to know where to start. To help, we've put together the following list of the most popular slot games in the UK right now. These games are frequently eligible for bonuses, but always read the small print to be sure.

How We Review the Best Slots Bonuses in the UK

Here at akfxoqsd.shop we do things a little differently. In fact, one of the reasons that we launched our site is to change the way casinos are reviewed. We don’t want to throw up a generic review and instead, we want to go deeper and be more genuine than other casino review sites.

Our Team of Experts

To do this, we’ve created a dedicated team for each aspect of online casino. This team is set up to find every great online slots bonus, and explain how each works and compares to the rest.

Our team includes professional casino players, game developers and casino writers. The team can cover reviews in greater detail than a one-man-band.

With each review, there’s a basic guideline our team follows, however, it’s not set in stone. And new slot sites pop up all the time, so we try to test all the best new online casinos when they hit the market.

Assessing Bonuses

The first port of call is the bonus and the amount of money on offer. ‘The bigger the better’ is a common misconception as wagering requirements also play a part. Working through wagering can be challenging so we make sure all the terms and conditions set out by the casino are explained clearly.

Wagering contributions include the amount needed to clear the bonus for withdrawal, the time limit on the bonus, games included, and the maximum bet allowed with bonus money.

Evaluating What Each Casino Has to Offer

Once the bonus is reviewed, we move onto the wider casino and the number and quality of slot games. This includes the number of mobile slots online that are accessible, since many of you love playing slots on-the-go.

It’s worth noting that lots of casinos use the same game providers and have many of the same slots, so we give extra points for an original range of great slots. We also love it when a casino offers progressive jackpot slots and a healthy selection of Megaways slots.

Banking and customer support options are key to our reviewers too, as these can make or break your experience. The website might have the best games and bonuses in the world, but if you can’t get money in and out, it’s pointless.

We test bonuses and casinos every day, so check this page later in case we find even better slot bonuses.

Terms and Conditions: What are Wagering Requirements for Slots Bonuses?

The main concept behind wagering requirements is to make sure players don’t simply take the bonus money and run.

A typical offer would be based on 30x your bonus, meaning a £100 bonus would need £3,000 worth of wagers to clear that bonus (30 x £100). 

If you can win and bet £3,000 using the initial £100 bonus money, then you’ll be able to withdraw anything else as cash. The bonus money doesn’t become real money until you reach this point.

Exclusions

Bear in mind that some games will be excluded from wagering — usually, live casino games like blackjack aren’t included or they only count 10%. On the other hand, casino slots usually count 100% to wagering, although some slots are excluded.

What’s more, some payment methods can't be used to deposit and claim bonuses, and you generally have to withdraw funds with the same payment method you used to deposit with. You should also remember that most online slots bonus funds expire after a certain number of days.

Is There a Limit on How Much You Can Deposit at a Slot Site?

Yes, while many casino websites offer you the best casino payment methods, you should know each has its own deposit and withdrawal limits, and withdrawal times.

Generally, debit cards and bank transfers offer the highest deposit limits, with e-wallets and prepaid cards being lower.

Do All Slots Bonuses Require a Promo Code?

Very few bonuses come with a casino promo code these days but some still do. Just remember to keep an eye out for a bonus code, so you don’t miss out.

You need to enter the bonus code before making your first deposit or at the time of doing so. You won’t be able to go back and add one if you forget.

Wagering Calculator

If you’re still confused about wagering requirements, you can try our wagering calculator (which opens in a new window when you click the image below)! This makes it easy to understand how much money you need to bet through before you can withdraw your bonus. Just type in your deposit amount, the bonus percentage on offer, e.g. 200%, the wagering requirement, and how much the game, e.g. slots or blackjack, contributes to the bonus, and you'll see how much you need to bet using your bonus money.
