The Best Halloween Slot Games

When Halloween comes around every year, only the spookiest slots will do for us here at 21.co.uk, our library of slot games is huge, so manually finding the best slots in this category would be a challenging task; with that in mind, we've brought the biggest and best Halloween slots to one location! So whether you're looking for a spooky slot or a slot with a dark or mysterious theme, we have a game for you!

We'll list our top Halloween slots below, and if none of them takes your fancy, we'll leave a wide range of other games that you may wish to play during the spookiest night of the calendar.

The Top Halloween Slot Games

Devil Themed Slot - Devil’s Number

Vampires, Witches, Werewolves and Devils are some of the main characters in Halloween slot machines, and we wanted to ensure they were covered in our Halloween slot games list.

Devil's Number by Red Tiger, a slot that ultimately stands out in any slot library. The creepy, wicked design is something unseen in most slot games. If you're into comic book-style graphics, then this game will pique your curiosity with a dark, mysterious library backdrop accompanied by the head of a horned character.

Look out for the Mark of the Beast, which is a randomly triggered symbol upgrade and removal feature. In some scenarios, low-paying symbols will be removed, and in others, low-paying symbols will be upgraded. However, where the biggest payouts in this Halloween slot will come from is the Free Spins feature, which is a bonus game that is activated by landing three nine symbols on the central reel, which then turns upside down to reveal - the Devil's Number!

The beast draws near, and the soundtrack takes a metal turn; both Mark of the Beast features are consistent throughout your 12 Free Spins, and any upgrades or removals will last for the entirety of the feature. In theory, you could remove all low-paying symbols from the game after 5 Free Spins in this bonus game.

Werewolf Themed Slot - Curse of the Werewolf MEGAWAYS

We started with Vampire slots, and now as the full moon gleams, we're bursting into a new form with one of our top Werewolf slots, Curse of the Werewolf MEGAWAYS by Pragmatic Play.

While the first option explored the haunting theme of Forbidden love amongst Vampires, our second Halloween slot takes a completely different approach, with the fearsome cursed Werewolf looking to feast on wildlife and leave the local town unoccupied. So, in this slot, you can join the townspeople in repelling the Werewolf, uncovering the beast's curse, and lead them to potentially valuable treasures along the way.

In regards to how the game plays, Curse of the Werewolf MEGAWAYS would be a fantastic slot even if we removed the theme. With over 40,000x your stake as the win potential and over 46,656 paylines, set the tone for things to come in the main bonus game of the slot.

Alongside the mystery symbols, which can provide two Spin Modifiers, these are the Super Spin and the Guaranteed Win, there is a Free Spins feature, where if you land three to six bonus symbols during a single spin, you'll be able to receive between 8 and 15 Free Spins and enter the bonus round. During this bonus, locals will turn into Golden Werewolves, which become the most valuable symbol. If a local turns into a Werewolf, you'll receive an additional Free Spin.

Vampire-Themed Slot - Immortal Romance

Immortal Romance is an online slot that was released in 2011. The tale of passion and the paranormal is one that has entertained fans of the slot for over 10 years. However, it is the theme of the game that makes the game so unique. The creators of the slot, Microgaming, have created a slot game based around the story of love, hence the term romance, but the theme lies much deeper than any could imagine, with a dark, mysterious soundtrack helping to portray the story of forbidden love. It also tributes one of the most famous characters in horror history, Dracula himself. The gothic theme is befitting of a Halloween slot, but the modern elements of the slot ensure that the game feels current rather than medieval, even 10 years since it was released.

With Vampires and Witches running wild, can you lock in 5 wild symbols and land 1,500x your stake? Or will you aim to push down the route of bonus rounds? If your preference for these slots is the latter, you may look at the four different bonus rounds in the Immortal Romance slot game. Here, there is a bonus feature for the four characters in the slot, Amber, Troy, Michael and Sarah. The four bonuses offer different features such as Multipliers, Rolling Reels and additional wild symbols. They also differ in total, with one feature offering up to 25 free spins.

Zombie Inspired Slot Game - Zombie Carnival

Find zombies lurking around the grounds of this carnival, with various mutations existing and bringing about brutish zombies and smaller clown-dressed zombies.

As the reels of the slot rotate in Zombie Carnival, you can view the various Zombie characters as they drop onto the reels as the game’s paying symbols.

Set within the backdrop of the slot is a zombie-infested carnival where we can see overgrowing grass and circus tents.

Throughout the game, there is the potential for bonus features to trigger, including options such as the free spins round and transformational scatters.

Classic Halloween Theme - Horror Hotel

View the rocky cliffs that create the base of the Horror Hotel, which is set high within the moonlit clouds of this dark, mysterious world. The slot takes inspiration from popular Halloween characters such as Frankenstein, Dracula, Mummies and Werewolfs, all of which are guests at this unwelcoming hotel.

Across the reels of the slot, you can find each of the characters appearing as symbols, which includes a Vampire, Werewolf, Mummy and Frankenstein. There are also the lower-paying symbols which can come in the form of potion bottles.

Throughout the game, there is the potential for bonus features to trigger, which can include mystery symbols and free spins.

English Folklore-Inspired Theme - Spring-Heeled Jack

Based on old English folklore, the Spring Heeled Jack slot is a perfect fit for Halloween slots, given the dark and mysterious design of the game.

Within the slot, you will find the dim-lit streets of an old English town which is crawled by the character of Spring-Heeled Jack. Smoke spills from the Victorian chimneys, resting just above the streets to add to the Halloween atmosphere of the slot.

This slot does include a range of bonus features which can come in the form of the free spins round, mystery symbols, and win multipliers.

Sinister Slot Design - Mental

Created by the providers, Nolimit City, the Mental slot includes all the typical designs and features we can associate with Nolimit City, helping to make its way into the list of Halloween slot games.

The slot is based within the dark cells of a facility where you can see various sketches appearing as symbols on the reels. These include skeletons, characters, hearts and eyes, all of which come with a dated design to complete the theme of the slot.

Within the game, there is a wide range of bonuses which maintain the theme of the slot. This includes Fire Frames, Enhancer Cells, Autopsy Free Spins and more.

Gloomy Slot Design - Book of Shadows

Rooted within the dying forest of the Book of Shadows slot, the reels sit with varying character symbols and items that fit within the Halloween nature of the slot.

The slot’s symbols can come in the form of cursed books, peering cats, and skulls, all of which maintain the theme of the game.

In the 5x3 reel slot, there is the chance for bonus features to activate, and this can include expanding reels, free spins and the lucky lock bonus.

Haunted Mansion Theme - House of Doom 2: The Crypt

Inside the eerie House of Doom, stone pillars stand up tall with hooded characters holding swords on either side of the reels. When spinning the reels in House of Doom 2: The Crypt, there is a chance for different characters to appear as symbols. Each of these characters is fitting to the theme and helps to complete the Halloween slot theme.

Aside from the character symbols, there is also the possibility that wax candles, spiked skulls and crossed swords land on the reels, further adding to the gothic design of the online slot.

Dracula Themed Slot - Fat Drac

The online slot, Fat Drac, is designed perfectly within the theme of Halloween slots with its unique concept and inspiration from one of the most popular Halloween characters.

For those who are familiar with Dracula, this slot will provide familiar references as it offers an original twist on the character.

Throughout the slot game, you might notice the game’s characters appearing, one of which is Fat Drac himself, who acts as a Reveal and Scatter symbol.

When it comes to bonus features, there is a selection that can potentially be activated, starting from free spins through to the Fat Bat feature.
