All British Casino has long held a strong position in our rankings, and its welcome offer is one of the best slots bonuses around. Once I’d signed up, I made the minimum deposit to claim. This is set at £20 at All British — a little high for my liking when other casinos require just a £10 deposit, but still not a major issue. The bonus itself is a 100% match up to a substantial £100, which can be used on a huge range of slots and table games alike. In my view, this flexibility is a key benefit compared to other slots bonuses which may just be valid for one or two titles.

This bonus comes with 35x wagering requirements. While these aren’t competitive by any means and make a winnings withdrawal unlikely, they’re pretty standard as slots bonuses go. There are a few other stipulations to be aware of. Skrill and Neteller deposits are excluded — fortunately, All British Casino has a range of excellent alternatives like Trustly, PayPal, and Apple Pay. There’s also a £5 maximum bet when using the bonus credit.

As far as the rest of the site goes, the library is fantastic and everything runs smoothly on mobile too. Another thing I love about All British is its 10% cashback that’s always available, giving you a little more for your money when you play slots at this casino.

Hyper Casino treats new players to one of the best slots bonuses around — a 100% bonus up to £100 which can be used across the games library. One of my favourite things here is the £10 minimum to claim, so it’s a fantastic offer if you’re on a lower budget. And considering Hyper’s fantastic slots library from top developers, I had a great time using my bonus to find some new favourites.

As is the case with most slots bonuses, there are wagering requirements attached. I was disappointed to find these are a little steeper at Hyper Casino, set at 45x the bonus. That said, this doesn’t make much practical difference compared to offers with lower wagering, as withdrawing your winnings is pretty difficult even with requirements as low as 20x. Another stipulation to watch out for is the exclusion of Neteller and Skrill deposits. On the plus side, you get 30 days to use the bonus.

I really like the design of Hyper Casino overall, and its site feels snappy and responsive. I also received a fairly fast withdrawal here, with my Trustly cashout arriving the next day.

You’ll find a bit of a different set-up at Luckster when it comes to slots bonuses. Here, the offer is split over three deposits, which has both benefits and drawbacks. Kicking things off is a 100% match up to £50 and 20 spins on Book of Dead. To me, this is the most valuable part of the bonus, particularly considering there’s just a £10 minimum to claim. Plus, I like that it combines the flexibility of a deposit match with a handful of free spins to throw on Play’n GO’s much-loved slot. Your next two deposits of at least £20 are rewarded with 40 free spins on Fire Joker and 9 Masks of Fire — I don’t think this is great value for money, but it’s a nice sweetener if you were planning to stick around anyway.

The wagering requirements are par for the course at 35x, so a withdrawal of any winnings is pretty unlikely. Players get 21 days to use their bonus as well, which I think is a reasonable length of time considering it’s not the largest bonus going.

Another key highlight of Luckster is its range of payment methods, including favourites like Paysafecard and Trustly plus newer options like AstroPay. All methods support instant withdrawals too, except for wire transfer.

I’m a big fan of the slots bonus at VoodooDreams. Like a few other sites, it combines a matched deposit with free spins to give you the best of both worlds. The match portion is 100% up to £50, which gives you plenty of bonus credit to sample the library. But what really excites me is the free spins — new players get 50 to use on Book of Dead, and any winnings are credited as real money with no wagering requirements. That’s one of the best value slots bonuses going in my book!

Of course, there are a few things that hamper the bonus. The match portion is subject to 30x wagering on your deposit plus bonus, and there is a minimum deposit of £20 to claim. But I think the no wagering free spins more than make up for this.

One more thing to differentiate this site from the rest is its fantastic loyalty scheme, based on player-vs-player duels. I’m a big fan of casinos that offer something entirely unique, and VoodooDreams definitely checks this box!
18+ new players only. Maximum £50 bonus. Minimum deposit: £20. Deposit Bonus wins are capped at £500. Max bet with active bonus: £2. Wagering requirement 100% match deposit bonus: 30 times sum of deposit + bonus. Winnings from Free Spins are credited as Real Money without wagering requirement.

If it’s simply size you’re after, Mr Play’s welcome package is one of the biggest slots bonuses around. It’s a little more complex than other offers as it’s split across three deposits. First up is a 100% match up to £50 and 20 spins on Starburst. Personally, I’d rather see a more imaginative title chosen for the free spins — but Mr Play has a few tricks up its sleeve. You’ll also get an additional 20 daily free spins over the next four days, which can be used on Starburst, Book of Dead, and Legacy of Dead. Your second and third deposits are met with a 50% match up to £75 too.

The welcome package comes with 35x wagering requirements attached to the deposit matches and free spins alike. So, withdrawing your winnings is pretty unlikely. Nonetheless, I think this is one of the best slots bonuses if it’s a large amount of free play you’re after.

I’m not a huge fan of this site’s design, but I’m sure some players will enjoy its casual and lighthearted approach to things.

Another top slots bonus comes courtesy of PlayFrank, an online casino with a jaunty, cartoon-like design. This isn’t necessarily the most creative bonus I’ve seen — new players get a 100% match up to £100 and 50 bonus spins on Starburst. But all things considered, it’s a flexible offer that lets you try out some of PlayFrank’s formidable games library.

There are a few T&Cs that could trip you up if you’re unaware of them. First, Skrill and Neteller deposits are excluded. You’ll also have to use your bonus spins within 24 hours. For the bonus credit, there’s a maximum bet of £4. Finally, the wagering requirements are set at 35x, so withdrawing your winnings is unlikely.

I do like the clean layout of the site, which makes it easy to browse and find your favourite games. The Daily Challenges section offers an extra slice of entertainment as well, with different rewards to pick up every 24 hours. Throw in a top selection of payment methods and PlayFrank is an excellent destination for any slots fan.
New players only. Min deposit £20. Bonuses to a max of £100 + 50 spins. Wagering bonus 35x. Wagering bonus spins 35x. The winnings must be wagered within 21 days. Bonus T&Cs apply 18+ Please Gamble Responsibly. Click 'Claim Bonus' to view the full terms and conditions.

It’s free spins galore at Griffon Casino. Here, new players can bag up to 200 free spins across their first three deposits — 50 on Book of Dead, 50 on Starburst, and 100 on Fire Joker. While I do like it when casinos extend their offer past the first deposit, it’s hard to say this deal is particularly good value. Each portion of the slots bonus requires a £20 minimum deposit to claim, so the deal is effectively £60 for 200 free spins. Considering the 35x wagering requirements too, you probably won’t be withdrawing any winnings here. On the plus side, I was glad to see a bit of variety in what the free spins can be used on.

Griffon’s library is pretty packed, with over 1,750 titles to choose from. I was also impressed by the banking options at the site, including four different e-wallets along with Trustly, Paysafecard, and debit cards. I would like to see the ongoing promotions rounded out, as there’s not much on offer currently.
18+. Welcome bonus: new UK depositing players only. 200 spins require 3 deposits of min. ‎£20 each and are issued as follows: 50 on 1st deposit, 50 on 2nd deposit and 100 on 3rd deposit.

We’re not quite sure why GenerationVIP is so preoccupied with the number seven, but it’s not important — new players at this site will bag a 100% match up to £77 and 77 free spins. Again, flexibility is handy if you’re looking to try out a range of different games using your slots bonus. I was pleased to find a £10 minimum to claim this offer, which makes it a good option for smaller budgets. As for the 77 free spins, these can be used on Starburst. 35x wagering requirements are attached to both the deposit match and any winnings from the free spins, so you probably won’t get to withdraw any profit. That said, there’s good free play mileage to be had in this slots bonus.

Another feather in the cap of GenerationVIP is its excellent selection of live dealer games if you’re interested in this category. Players are also automatically enrolled in the site’s loyalty scheme — the clue is in the name — which lets them earn points and pick up monthly bonus credit.

Owned and operated by Marketplay, VegasLand features a similar welcome bonus to many of the other sites under this white label’s umbrella. It’s split over three deposits, offering 100% up to £50 on your first, and 50% up to £75 on your second and third. There’s also a chunk of free spins thrown in on each instalment, which can be used on Starburst, Book of Dead, and Legacy of Dead.

I do like this offer — the first deposit bonus is just a £10 minimum, so you could claim that and call it a day. But it’s nice to see this casino keep things rolling on your second and third if you stick around. Of course, things are stymied somewhat by the 35x wagering requirements, but these are par for the course with even the best slots bonuses. Instead, VegasLand’s welcome package makes up for it with size, giving those who claim a substantial amount of free play.

Despite this decent slots bonus, I do think VegasLand has some work to do on the design front. Its library is excellent, but it’s a little difficult to browse with the current layout.

Types of Slot Bonuses

There are a number of different slot bonuses on offer at the best UK online casinos. Let’s take a look at the most popular deals.

Free Spins

The number one online slots bonus, free spins bonuses do exactly as the name suggests – let you play online slots without dipping into your bankroll. Lots of top UK casinos offer 100 free spins, while you can claim as many as 200 free spins at some slot sites. You’ll usually need to make a minimum deposit in order to access your bonus- some casinos award a set number of spins, while others will reward spins depending on the size of your first deposit.

A matched deposit usually comes with free spins as part of a welcome bonus package, and rewards players with bonus funds worth a percentage of their first deposit, up to a certain amount. A common example is the 100% deposit match bonus, where a player would earn a £200 bonus if they made a deposit of £200. These bonuses can be used on table games like roulette and blackjack, but can also be used on slots.

Some casinos go one step further and offer free no deposit slots bonuses which give you bonus funds simply for signing up- no deposit required. Most of these bonuses are no deposit free spins, though a few casino sites offer no deposit bonus funds. These offers are generally more modest—-20 free spins or £5 cash, for example—-but they give you the chance to play real money slots and try out a new casino at no expense.

The slots bonuses don’t dry up after you’ve used your slots welcome bonus- there’s a whole range of regular promotions on offer at the top slot sites. Happy hour free spins is a pretty common bonus, where you can bag some weekly free spins during a specified timeframe, while some casinos also offer free spins to promote new slots releases. These are just a couple of the many slots promotions available at online casinos, so don’t forget to weigh up the regular deals when comparing sites to find the best suited to you.

While free spins promotions are usually open to all players, some slot sites have VIP schemes to reward frequent players with bonuses and perks. These VIP schemes are usually tired, and your tier level depends on how often you play real money casino games. Free spins are just one of many potential VIP bonus rewards, while some casinos also offer other VIP perks such as exclusive access to the latest slots and personal account managers.

Slot Bonus Terms and Conditions

A casino slots bonus can be a handy bankroll boost, but the only way to judge the true value of an offer is by reading the terms and conditions. Here are the key factors to look out for when reading the small print.

Wagering Requirements

Unless you bag a no wagering bonus for slots, you’ll have to wager your bonus winnings a set number of times before they can be withdrawn as real money. Wagering requirements can vary massively between sites, ranging from 25 times to over 60 times your bonus fund. So if you win £10 from your free spins with a 30x wagering requirement, you’ll have to bet £300 before you can cash in any returns.

Some casinos state that the wagering requirement also applies to your qualifying deposit, which can significantly increase how much you’ll need to wager before you can withdraw any winnings.

Luckily for slots players, 100% of wagers placed on most slots contribute to the completion of the wagering requirement. However, if you want to play table games like roulette or blackjack to complete the wagering, you should check the terms and conditions. The contribution percentage of these games can be as low as 10%  at some sites, meaning only a small portion of your bets contributes. Some casinos even exclude these games from wagering completion altogether, so pay close attention to the small print.

While some of the best bonus slot offers give you access to most titles in the games catalogue, you may find certain deals are restricted to a select number of games. Some offers, such as Starburst free spins, can only be used on one title, and some slot sites use free spins to promote brand new games. Keep in mind that most casinos exclude certain progressive jackpot slots from slot bonuses and promotions.

You’ll usually be able to win real money from your slots bonus, but the amount of money up for grabs depends on the casino. Some slot bonuses have relatively small win limits, such as £5, while others are much more generous. Make sure you check the win limits beforehand, as they have a big influence on how valuable a casino’s slots bonus really is.

Just like other casino bonuses, you’ll have a limited amount of time to use your slots bonus. After this time your bonus will expire and the bonus funds or free spins will become void. The time limits can range from a day to a month, depending on the casino.

Not all deposits are always eligible for bonuses! It’s fairly common for casinos to exclude Neteller and Skrill deposits from bonuses and promotions. A few casinos may also exclude other payment methods like PayPal and pay by phone bill casino deposits, so check this out before signing up to a bonus.
