The Best Halloween Slots in The UK: Top 13 for 2025

Top 13 Halloween Slots to Play In 2025

There’s something eerily exciting about Halloween and we’ve decided to celebrate with our very own list of the best Halloween-themed slots you can play online. We went through an entire JohnSlots Halloween category and put together a list of the top 13 (whoa, spooky number) titles. You can play to help you celebrate this pumpkin season and bring you a jolly-frightful time!

Our list includes a great variety of games, including high-volatility slots, Megaways, pick-me bonuses, mini-games and more. Take a look at the selection we’ve compiled and you’re bound to find the right game for you this Halloween season.

1. Big Bass Halloween

Who knew fishing could be so scary? Well, Reel Kingdom’s Big Bass Halloween takes everything you love about the popular series and gives it the Halloween treatment. The friendly fisherman turns into a strangely terrifying, hook-wielding serial killer and all the fish you catch have undead features.

But while the visuals are adapted significantly to fit the theme, the features remain identical to what we got in the original release. Your aim remains to access the free spins bonus through scatter symbols and then catch pay symbols using wilds. The base game can feel like a bit of a drag since it has no special features to speak of, but you can bring in some significant wins during the bonus rounds.

We weren’t particularly fans of the math model though. Although its medium to high volatility works well enough, the maximum win cap has been reduced to 2,100x. It’s quite a big difference from the original, which makes you wonder if the Halloween theme is worth the downgrade in maximum payout.

While fans of the series might be satisfied to carry on playing with the same mechanics in this different setting, this spooky version of the game won’t bring in any players who didn’t enjoy previous entries.

If you’re a fan of the Big Bass series and you want to try out its spooky version, this is where you can play this slot and get some free Halloween spins while doing it:

2. Halloween Fortune

In Halloween Fortune, you’re pitted against three fiendish witches as you fight your way towards the whopping maximum prize of 10,000x your stake. Playtech’s slot was originally released in 2012, and while there is a nostalgic charm to the graphics, the game can ultimately feel quite dated. This becomes even more evident through the lack of animations which would truly make the screen come to life.

During the base game, wilds and scatter symbols help you reach for bigger and better rewards, while the bonus symbols unlock the free spins bonus. Once you hit the free spins bonus, you pick a witch to determine the number of free spins and a magic potion to decide your win multiplier. The gameplay remains largely the same during the bonus rounds, except for the win multiplier which boosts your wins further.

The online slot finds an equal balance between challenging and rewarding thanks to a medium level of volatility paired with a 97.05% RTP and a 10,000x maximum win. It can lead to some huge wins, but as always, it’s up to the game’s RNG to determine your luck.

If you’re willing to put up with some dated visuals and mechanics, then Halloween Fortune can still prove to be a spooky and rewarding slot this Halloween.

3. Infective Wild

Pragmatic Play’s Infective Wild is a thrilling slot machine that takes place in what looks to be a cemetery and has a creative virus-themed idea where contagious wild symbols travel across the grid, converting nearby symbols wild to enhance your winning chances. Thrilling music and quick-paced action provide an exciting time for players as they spin the reels.

Infective Wild is a fun choice for users looking for rewarding slots since it offers a satisfactory Return to Player (RTP) rate of around 96.50%. For a second consequent year, it takes up the third place in our list of most popular Halloween slots.

4. Reel Spooky King Megaways

Everyone’s favourite Reel King is back but this time round he seems to be suffering from a serious case of vampirism. Inspired Gaming has done an excellent job of reworking the visuals to suit the Halloween theme. It falls more into the whacky side than anything we’d consider scary, but it’s fun to see the way that the original symbols and backdrops have been adapted to fit this new setting.

When it comes to features, everything effectively remains identical to the first game too. You get wild symbols and cascading reels, which interact with the lit reels function to activate the Reel King features. There are three of these, each offering increasingly better bonuses that will help you ultimately hit a more rewarding free spins bonus.

Volatility remains fixed at a medium setting and Megaways gives you the standard 117,649 ways to win, but the RTP has unfortunately been reduced. It’s taken down to a disappointing 95.56%, which is below the average that we’d accept for a game like this. It can also be the reason why some players choose to stick to the original game instead of the Halloween alternative.

Quite frankly, we enjoyed the Halloween setting for Reel Spooky King Megaways and the features work just as well as they did in the original game. However, the reduced RTP is a significant downgrade when compared to the previous release. If you still want to try it, you can do so at 32 Red Casino, which is one of our top casino picks for Halloween promotions this October.

5. Lucky Halloween

Red Tiger Gaming delivers a game layered with fantastic features and jaw-droppingly gorgeous graphics with Lucky Halloween. The online slot boasts the provider’s trademark high-quality visuals with the theme centering around a pumpkin-head biker who rides around a graveyard causing mischief and mayhem. The designs and soundtrack are a joy to experience and the animations bring the screen to life every time a symbol lands or the biker randomly rides across the screen.

Whenever this happens the biker triggers a random reel modifier that can add several wild symbols, a mega wild symbol, matching symbols, scatter symbols and more. It’s an absolute treat and makes base game spins feel like real fun instead of a boring chore. You also get a free spins mode with increased biker appearances and a pick-me bonus mode that can get you huge cash prizes.

The math model can be a bit tricky though. Volatility is set to a high setting and RTP is at a rather low 95.07%. To make matters worse, the maximum win is capped at 800x your bet.

But despite these setbacks, Lucky Halloween is easily one of the most fun Halloween-themed slots out there.

6. Halloween Horrors Megaways

Werewolves meet witches, mummies and Frankenstein’s monster in 1×2 Gaming’s Halloween Horrors Megaways. As with most Halloween-themed slots, the action takes place in the middle of a graveyard, where these monstrous creatures rise to guard the 25,000x maximum win prize. The slot may not have the best visuals on this list, but it’s close enough, with great designs and animations accompanying a moody soundtrack.

The feature list is simple enough, with wild symbols providing the most action during base game spins. The aim is to get consecutive wins through the cascading reels function and enough of these will trigger the free spins bonus. During this phase, all seven-row reels are locked in, helping you push for the maximum number of Megaways. You’re even given a win multiplier that boosts your wins further.

Despite the high maximum win prize, you’ll need to deal with a very high level of volatility, paired with an RTP of 96.13%. It makes for a rather challenging game, where wins and special feature triggers are rare but also immensely rewarding.

Halloween Horrors Megaways is the perfect game for hardcore enthusiasts who enjoy a challenging time at the reels. Even so, we would have preferred to have more layered features to make the long base game wait more worthwhile.

7. Halloween Jack

Proclaimed the spookiest slot in NetEnt’s collection, the Halloween Jack game tells a scary story of the girl who found a cursed jewellery box and unleashed a great evil when she opened it. Ever since, at midnight on the All Saints’ Eve, the reels are seen haunted by stacked hellhounds, roaming Jack O’Lanterns and the scariest of them all, expanding Death the Reaper wilds.

8. 3 Lucky Witches

4ThePlayer replaces 3 Lucky Leprechauns with 3 Lucky Witches and adds in a spooky Halloween theme set outside of the witches’ coven. The visuals are on point, with a wonderfully mysterious backdrop and several witch artefacts serving as the game’s symbols. It follows the usual Halloween setting but manages to stand out anyways thanks to its fantastic animations and engaging art direction.

While there is plenty of fun to be had in the base game spins, particularly with wild symbols, the real action happens once you activate the bonus modes. There are three of these, offering a witch wheel with instant cash prizes, free spins with a win multiplier and a pick-me bonus with wins of up to 590x your stake. The variety on offer here is fantastic and during our test of the game, we managed to trigger all three bonuses several times.

The math model is fairly even too with a high level of volatility and a 96% RTP. The maximum win may not be as high as some of the games on this list, but you could potentially take home up to 5,000x your stake.

Overall, 3 Lucky Witches is a great successor to 3 Lucky Leprechauns with better features, stunning visuals and a solid math model.

9. Book of Halloween

Open the Book of Halloween and you can be treated to wins of up to 2,500x your stake. Inspired Gaming’s Halloween-themed online slot follows the usual ‘book of’ game formula, complete with a double function scatter/wild symbol and a special feature embedded in free spins. In terms of visuals, the video slot holds up immensely well, sporting a Tim Burton-like style that adds a whimsical twist to the spooky Halloween graphics.

Features are quite simple here. Wild symbols add some excitement to the base game spins, while free spins come with special symbols that expand to cover their entire reel. There’s also a gamble feature that lets you boost your wins by up to 5x their original value, as long as the win you made in the first place is worth more than 5x your bet.

This time around, volatility is clocked to a high setting and paired with an RTP of 96.23%. It makes for an even math model, but our biggest gripe here is that to reach the 2,500x maximum win, you have to use the gamble feature, which risks losing your entire win.

If you’re into ‘Book of’ video slots, then Book of Halloween will be right up your street. But with a lack of innovative new features, we’d say the game is unlikely to draw in new converts.

10. Granny vs Zombies

Granny vs. Zombies is an action-packed slot that blends humour, horror, and adventure. An endearing and tenacious grandmother heroically battles a horde of merciless zombies in the game. Wild symbols, bonus rounds, high volatility and free spins are just a few of the slot’s exciting features that increase your chances of hitting the max win of 5,000x your stake. This year Granny vs. Zombies dropped from the 7th to the 10th spot in our top Halloween slots list but still here unlike many dropouts.

11. Pumpkin Smash

This Yggdrasil slot released in 2017 is themed around two scary celebrations – the Mexican Day of the Dead and Halloween! It offers 5 reels, 20 paylines, and a medium variance with a 96% RTP. Players can bet between £0.10 and £100, with a chance to win up to 100,000x their bet.

The game features Wilds, a Pumpkin Smash bonus game, and a Free Spins feature, all complemented by rich animation and a fitting soundtrack. It is obvious Yggdrasil prioritized the gameplay and design features over the jackpot wins. And as with the rest of the Halloween slots on this list, you can play Pumpkin Smash in demo mode on its dedicated slot review page. Check it out or dive directly into the real money games by grabbing Barz’ casino bonus spins below:

12. Blood Suckers 2

If True Kult isn’t frightening you enough, then Blood Suckers 2 will scare the pants off any player in favour of some real deathlike action. Arm yourself with wooden stakes and follow Amilia into the creepy gothic castle to hunt the garlic-fearing vampires. The follow-up to one of NetEnt’s beloved classics, this 5-reel and 3-row slot provides some atmospheric moments while you try to find the hidden treasure.

Blood Suckers 2 keeps the 12th spot in our list for two consequent years, still relevant during the Halloween free spins bonus hunts.

13. Mental

Located in some dingy mental institution in the middle of nowhere, this 5-reel slot is one of the latest horror shows from Nolimit City. xWays, xNudge, dead patients, lobotomy free spins, autopsy free spins – you get the picture.

If you’re looking for something truly sinister to play this Halloween, Mental is more than capable of giving you the shivers! It’s incredibly volatile and offers 9 disturbing bonus features leading towards a possible max win of up to 66,666x your stake.

Types of Spooky Slots by Theme

Whatever spooky film or TV show you remember watching about the brain-eating living dead, spooky ghosts, blood-thirsty vampires or undead Pharaohs, there’s a slot for it. Below we’ve shortlisted the top six most popular slots with a spooky theme. These themes explore the most fearsome and yet fascinating world of supernatural beasts.

Mummy Slots

Egyptian slots

The art of preserving ancient Egyptian pharaohs evolved from a long-lost tradition to the makings for a horror movie long ago. These bandaged monsters can be the stuff of nightmares if awoken. The bottom line is, where there are mummies, there’s a treasure to be found. And that’s why several gaming providers have found mummies to be the perfect basis for intriguing online slots adventures.

Zombie Slots

Zombies have been the topic of many horror films over recent years (along with plenty of spoof movies and series too), and the world seems to have a fascination with them. The concept has also spread as fast as a zombie virus to the world of slots. Top gaming providers have found fun new ways to incorporate these monsters into their slots.

Ghost Slots

They’re some of the most recognisable Halloween characters of all time (not to mention the easiest costume to create) – and ghosts have been the basis for Halloween stories for centuries. Whether they’re friendly, out to seek revenge or simply haunting your local halls for eternity, there are plenty of ghost stories to tell, and plenty of slots that do it well.

Werewolf Slots

Subjects of many tales and scary stories across the world for generations, these mythological morphing beasts have become quite the celebrities among fans of Halloween themed slots. These creatures often cause havoc, inflict fear and sneak up on unsuspecting villagers in the night, but they can also be rewarding if you pick the right game.

Vampire Slots

One of the most seductive monsters ever dreamed up; the vampire has been prominent in literature, film and television for decades. These blood-sucking day walkers have now also made their way to slot games, where they’re luring players in with the tempting prizes waiting behind the reels.

Day of the Dead Slots

The Day of the Dead slot theme has perhaps the most authentic ties to Halloween. Widely celebrated throughout Mexico, this multi-day holiday has proved to be the perfect backdrop for some of the most recognisable titles in the horror slots category. Rather than being spooky like the ghost or zombie games, these types of slots are bursting with colour, bone-rattling mariachi tunes and, of course, Calaveras, the famous sugar skulls.
