TOP 15 HORROR SLOTS IN 2024

There are hundreds of different horror themed online slots. This theme is very popular, so much so, that there was a lot of research involved in coming up with a top 15 list of the best ones. Let’s get straight into it.

1. TOMBSTONE RIP BY NOLIMIT CITY (RTP: 96.08%)

A western/horror theme, I believe that Tombstone RIP is one of the best slots from NoLimit City not least because of its record high potential max payout of 300,000x, making it the best paying slot currently available. This slot also shows some humour from the development team at NoLimit City. Just as I was about to begin the game a message popped up asking if I was ready to risk playing Tombstone RIP when Fruit slots are available. The duel had begun – of course I am ready!

You should be aware that Tombstone RIP is one of the most volatile slots ever developed. This means that if you do decide to play, there will come moments where you can spin the reels plenty of times without triggering any wins. This goes the other wat too. As yo can see in the image above, I actually won £65.60 on just my fifth spin into the slot with a £1 bet. I then spun through almost all of my winnings before hitting another win for £73.60. The Hang symbols are the ones you want to try to hit as they will turn into wild symbols.

Slot Features:

• Free spins
• Bonus game
• Multipliers
• Wild symbol
• Scatter symbol
• xNudge wilds
• xSplit wilds
• xSplit
• xBet
• xNudge
• xRIP
• Hang ’em high free spins
• Boothill freespins

2. BLOOD SUCKERS BY NETENT (RTP: 98.00%)

Our first vampire inspired horror slot to feature, Blood Suckers features a number of vampires and vampire brides on the slot symbols. Despite being released all the way back in 2013, Blood Suckers remains popular to this day and is found in the slots libraries of most UK online casinos. The reason for its popularity is partly down to its high RTP of 98%, but mainly due to the fun theme, graphics and number of fantastic features available.

Blood Suckers is played on a 5×3 grid with 25 paylines and is a low variance slot. Another advantage is the decent maximum potential payout of 1,014x your stake (pun intended).

Slot Features:

• Free spins
• High RTP
• Good max payout
• Fun theme
• Multipliers
• Wild symbols
• Scatter symbols

3. POSSESSED BY NOLIMIT CITY (RTP: 96.06%)

Probably the scariest slot on this page, Possessed is creepy from the beginning with a dramatic and foreboding soundtrack. As soon as you begin spinning you will be greeted by numerous horrors, the scariest of which being the possessed looking ghost lady! Despite its high volatility, I quickly booked two small wins whilst betting £1 per spin – although neither of the wins allowed me to win any money (£0.20 and £0.40).

The fiery book symbols count as the slots scatter symbols and there are three different types of spins available: Necromancy, Atonement and Beelzebub spins which require three, four and five scatters to trigger. The beginning of the Necromancy spins is dramatic to say the least with a priest talking in the background before the reels light themselves on fire – very demonic! During the round, you will frequently hear the priest speaking in Latin – probably to ward of foul demons. I managed to win a total of £32.95 during the Necromancy free spins – a little disappointing but very fun at the same time.

Slot Features:

• Free spins
• Bonus game
• xActivation
• xNudge Wild
• Infectious xWays
• Scatter sybmols
• Wild symbols
• Multipliers

4. OOH AAH DRACULA BY BARCREST (RTP: 99.00%)

Ranked by us as the joint highest RTP slot in 2024, Ooh Aah Dracula is a rather dated but still extremely fun video slot from Barcrest. With a maximum bet of up to £500, it is also a perfect game for high rollers who can help themselves to a 99% RTP when they bet on Big Bet Mode. Another advantage is the stacked wild feature which helps to increase the likelihood of big multipliers and entering the games free spins round.

Although the cartoony vampire theme is fun, it is a little dated given this slot was released in 2016. The only disadvantage we can see is the somewhat low maximum potential payout which is 457x the wager. Other than that, Ooh Aah Dracula is not only one of the top horror themed slots, it is also one of the best online slot machines in general.

Slot Features:

• High RTP
• Stacked Wilds
• Multipliers
• Free Spins
• Scatter Symbols
• Wild Symbols

5. GRIM THE SPLITER BY RELAX GAMING (RTP: 94.00%)

A mysterious skeleton/ghoul (or maybe it’s the grim reaper?) asks you to read your own fortune using his ghostly cards in this slot game from Relax Gaming. One of the major pulls this game has are the five slot jackpots on offer with the largest one usually at over £1 million. In addition, the jackpot “must be won” before it reaches the £3 million – so somebody has to win it!

As for the gameplay, the slot becomes a little more intense if you hit two of the golden bonus cards on the first few reels, as the cards are then revealed one by one with the free spins game activated if you do manage to reveal another bonus symbol. Any Wild symbol on the reels will trigger a win of some sort too due to the xSplit feature. Grim the Splitter is played on three reels and five rows, so in that sense its very similar to the standard slot games. But I believe this to be an excellent choice if you are on the lookout for some spooky slot games.

Slot Features:

• Free spins
• Bonus game
• Progressive jackpots (5)
• Scatter symbols
• Wild symbols
• Splitter feature

6. IMMORTAL ROMANCE BY MICROGAMING (RTP: 96.86%)

Our second vampire themed horror slot to feature, Immortal Romance is another oldie but goldie. Despite being released over ten years ago, it remains one of the best Microgaming slots and one of the most played horror slots of all time. With features galore, a high RTP and high maximum potential payout of 12,000x the wager to match, Immortal Romance is regarded by as one of the top slot games of all time due to its excellent gameplay and features.

The only disadvantage to playing Immortal Romance is that the graphics are slightly dated. However, this should not be too surprising given that it was released back in 2012.

Slot Features:

• Free spins
• Bonus game
• Multipliers
• Scatter symbols
• Wild symbols
• Autoplay
• Unique soundtrack

7. DR JEKYLL GOES WILD BY SCIENTIFIC GAMES (RTP: 98.20%)

A literature inspired slot with a horror theme for you now, Dr Jekyll Goes Wild is based on the novella by Robert Louis Stephenson and is renowned for its high RTP of 98.20%. Played on a 5×3 grid with 10 paylines, the theme here is original, indeed, there are no other slots like this one and Scientific Games did an excellent job.

As far as horror themed UK online slots go, this is a great one for anybody who has read Dr Jekyll and Mr Hyde and wants to play a slot with a high return to player level mixed with some scary slot elements.

Slot Features:

• High RTP
• Big bet mode
• Original theme
• Free spins
• Great soundtrack
• Scatter symbols
• Multipliers
• Wild symbols

Play at: Hyper Casino

8. SKELETON KEY BY IGT (RTP: 96.00%)

With spooky, ghostly hidden reels and an ever-watching skull, Skeleton is a lesser known slot from IGT but it is lots of fun. I played Skeleton Key whilst I was reviewing Skeleton Key and I managed to hit a few big wins. My favourite aspect is how the Skeleton Key will unlock one of the extra reels almost every spin – this gave the feeling that there was always something happening.

Some of the need-to-know aspects of Skeleton Key include its max potential payout of 83,333x, expanding reels, high maximum bet level and medium volatility. The tumble feature is also available, although this only really makes an impact if all of the expanding reels are unlocked. My experience playing Skeleton Key was positive, with the only negative being I could not trigger the bonus game even after 45 minutes of gameplay.

Slot Features:

• Free spins
• Bonus game
• Reel expansion
• Mystery symbols
• Tumble feature
• Scatter symbols
• Wild symbols
• Autoplay

9. BARON BLOODMORE AND THE CRIMSON CASTLE BY THUNDERKICK (RTP: 96.07%)

For those who are looking to try out an easy to play horror slot machine, then Baron Bloodmore and the Crimson Castle is the way to go. This is a fairly standard slot played on the usual 5×3 grid with 25 paylines. However, there are a few interesting aspects including mystery symbols and respins. The mystery symbol will cover three reels and rows on the grid and triggering one can in turn trigger a nice payout multiplier. As with most slots, if you hit two bonus symbols early on, then the game will slow down as we hope and pray for another bonus symbol to appear on the reels. Once I did hit the bonus game (I got three free spins), I managed to win £28 with a 38x multiplier.

Regarding the aesthetics of Baron Bloodmore and the Crimson Castle, the game is bright with vampires and skulls on the reels aplenty. You will also hear a chilling violin soundtrack and some wear wolves in the background. Although it is regarded as a high variance slot, it is not as high as slots like Tombstone RIP, so it is not so farfetched to see several wins in quick succession.

Slot Features:

• Free spins
• Respins
• Bonus game
• Multipliers
• Scatters
• Wilds
• Mystery symbols

10. ZOMBIE CIRCUS BY RELAX GAMING (RTP: 96.92%)

One cannot write about horror without including Zombie’s in one way or another and combining Zombie’s with a circus – an absolute nightmare for a lot of people I expect! Not a nightmare for us though as Zombie Circus is a genuinely excellent horror slot with a high return to player (RTP) of 96.92% and an interactive free spins game where you must select one of five creepy zombie’s to activate a certain number of free spins.

As I explain in the Zombie Circus review I wrote, when I played I picked the Zombie on the far left, (which you can see in the image above) and I won 10 free spins. Unfortunately, I only accumulated £9 during the 10 spins.

Slot Features:

• Free spins
• Bonus game
• Wild symbols
• Multipliers
• Scatter symbols
• Autoplay

11. SERIAL BY NOLIMIT CITY (RTP: 94.08%)

NoLimit City slots almost always have an edge to them, and Serial is certainly no different given what it is themed around. Due to its very original and hauntingly incredible theme as well as its extremely large maximum potential payout of an incredible 74,800x your wager, Serial is a top slot game.

As you can see from the image, Serial is inspired by serial killers. This slots symbols are full of creepy looking symbols and it is your job to put these criminals behind bars. Serial offers 243 ways to win and is regarded as highly volatile, which means there should be high payouts triggered. The only real disadvantage here is Serial’s low RTP of 94.08%. However, the large potential payouts should make up for the sub-par RTP.

Slot Features:

• Free spins
• Respins
• xSplit
• xNudge Wild
• xWays and Infectious xWays
• xBet
• Scatter symbols
• The Search
• The Kill
• xBizzare
• Multipliers

12. BIG BASS HALLOWEEN BY PRAGMATIC PLAY RTP: (96.04%)

An undead horror version of the fantastically popular Big Bass Bonanza, there is always an influx of Halloween slots around October down in order to take advantage of all things macabre. Big Bass Halloween is just a rethemed version of the original game, but that’s no bad thing due to how good the original still is. One of the symbols you should be on the lookout for here are the fish symbols which can payout multipliers f between 2x to 2,000x your wager. If the free spins are triggered, it is also possible to retrigger them if you collect enough hook-handed fisherman symbols.

The music is creepy in this slot and quite catchy too. The RTP is around average at 96.04% and payouts can reach a maximum of 2,100x.

Slot Features:

• Free spins
• Bonus game
• Scatter symbols
• Random money wins
• Respins
• Wild symbols
• Buy the bonus
• Autoplay

13. HALLOWEEN HORRORS MEGAWAYS BY IRON DOG (RTP 96.15%)

The one and only Megaways slot to feature, Halloween Horrors Megaways is a recently released game from Iron Dog. Unlike some of the other horror slots we have already discussed, Halloween Horrors Megaways has more of a lighter cartoonish feel to it. The symbols are exceptional to look at, especially if you enjoy monsters. This online slot game has a lot going for it including big multipliers and high payouts, but it is rather hard to trigger the free spins bonus game which is done by achieving four consecutive tumbles in a row.

I can recommend Halloween Horrors Megaways to anyone who prefers a more light-hearted look at horror, especially given the fact that the minimum bet per spin is just £0.10, making it a great slot for new players.

Slot Features:

• Free spins
• Multipliers
• Wild symbols
• Tumble feature
• Buy bonus game
• Autoplay

14. BLOOD HUNTERS BY LEANDER GAMES (RTP: 94.00%)

Themed around the tools needed to hunt vampires, Blood Hunters is the first and only online slot machine from Leander Games on our list. Another slot with low variance, Blood Hunters is great for beginners and players with low bank rolls thanks to its minimum bet of just £0.25. Released in 2022, the graphics are nice and it is an easy game to play.

The main negative here is the slots low RTP of 94%, which is unfortunately below average.

Slot Features:

• Free spins
• Bonus round
• Wild symbols
• Scatter symbols
• Multipliers

Play at: Playzee Casino

15. THE MUMMY BY PLAYTECH (RTP 95.91%)

Based on the hugely popular film starring Brendan Fraser, PlayTech did a great job in this slot which features a soundtrack from the film as well as appearances from several of the characters in the film. The best feature of The Mummy is the high max bet per spin of £500, perfect for high rollers. Despite this, we only recommend playing The Mummy if you are a lover of the film.

Unfortunately, The Mummy has a low RTP and low max payout. Most slots themed around films come with low RTP as the developers usually have to pay a premium to own the copyright.

Slot Features:

• Multipliers
• Free spins
• Good soundtrack
• Good theme
• Scatter symbols
• Wild symbols
• High max bet

EXPLAINING HORROR SLOT GAMES

Simply put, horror slot games are ones which have some sort of horror theme to them. They could be based around vampires or other supernatural creatures, or they could simply have a gothic theme to them. There are dozens of such slots, some of which have low volatility, some with high volatility.

All things are not created equal, and this saying certainly goes for online slots. There are tens of thousands of different online slots, ranging from good slots to bad ones, slots with life-changing jackpots available to penny slots designed for beginners learning how to play. In the past decade, greater technology has allowed the top slots developers to create slot games with simply incredible graphics. These new slot games have been able to take players to far away lands from ancient Egypt to outer space with themed slots. Recently, one of the hottest new trends in online slot games has been slots themed around horror.

POPULAR FEATURES

There are plenty of modern slot features available in horror slots, but there are not really any which are exclusive to these games. However, we can explain to you some of the better features which are often found in slots with horror themes.

RESPINS

Respins are common, but due to the fact that free spins are where the majority of the cash is won, they are one of the better features available. Some slot games do not offer free spins during the bonus game whereas others only allow the respins feature to be activated in the bonus game – it varies from game to game. Serial by NoLimit City has the respins feature.

PICK YOUR OWN VOLATILITY LEVEL

A new feature which is available to Wazdan slots is choosing your own volatility level. As we are sure you are aware, video slots all have a volatility level ranging from low to high. Dracula’s Castle allows gamblers to choose their own volatility.

STACKED WILDS

Stacked wild symbols such as those in Ooh Aah Dracula increases the chances of being able to complete multipliers, trigger wins and access a slots free spins round. When a wild symbol is shown on the reels, it can be stacked which means that they will appear on the reels for longer allowing other wild symbols to drop down, thus making it easier to trigger wins.
