Many people love exploring their spooky sides, particularly in the build-up to Halloween. The horror genre has always been a mainstay across all forms of entertainment, with fans finding it hard to get their fill of ghouls, ghosts, monsters, and maniacs. Online slot players are particularly enamoured with all manner of monstrous thrills, and luckily, there is a vast selection of titles for you to enjoy.

If you’re up for some online gambling fun with a dark edge, look at our selection of slots below that will give you the shivers while paying out huge rewards. We have hand-picked some of the most exciting titles from top developers that not only perfectly execute their Halloween themes, but they also have terrific bonus features, gameplay, and winning potential.

1. Dark King: Forbidden Riches

NetEnt’s Dark King: Forbidden Riches slot is a celebration of gothic macabre where you descend into the realm of a malevolent medieval monarch. The game displays a 5x3 reel, 20 payline grid with medium to high volatility gameplay.

Supernatural knights and magical gems appear on the reels and have their values boosted by occasional active multipliers. A cross-shaped hot spot pops up during the free spins round that transforms regular wilds into sticky ones while also giving you extra spins.

If you enjoy a fear-infused medieval aesthetic with a dark, brooding atmosphere, paired with moderate volatility and a decent winning potential of 2500x your stake, you could have the time of your life with this slot. 

2. Helloween

You can’t go wrong with a fine blend of power metal tunes and Halloween aesthetics and Play’n GO took up the challenge with this on-the-nose titled game. Helloween happens to be the name of the band that this slot is themed around, and their savage guitar stylings match the game’s overall creepiness with depictions of witchery and nightmarish creatures appearing as symbols on the 5x3 reel, 10 payline grid.

Pumpkin symbols take on the double duty of acting as both wilds and scatters, substituting for regular symbols, and triggering the Keeper of the Seven Keys feature wheel. The wheel contains 7 bonus rounds, each named after one of the band’s hit singles.

This game will also appeal to those chasing a large prize with a maximum bet of $100 and a top potential win of 5000x your stake.

3. Wild Walker

The prospect of being turned into a flesh-eating subhuman is terrifying to most people, but many of us love a good zombie story. Pragmatic Play seems to appreciate this, and the developer’s Wild Walker title embraces the brain-hungry undead in the 5x3 reel, 25 payline game. Prepare to battle hordes of zombies with courageous fighters and brainy scientists, while immersive features reward your efforts.

Stacked zombie wilds shuffle across the reels, and gas mask-wearing skulls are the scatters that trigger the progressive free spins game where extra reels can be unlocked to boost your winning potential. A decent maximum win of 4900x your stake could be yours if you can survive that long.

4. Mental

It would be easy to populate this entire list with games by Nolimit City as the iGaming studio is a specialist in creating unsettling and creepy slot experiences. Mental plays out in a dark and dingy secluded asylum where the reels display portraits of the unfortunate patients and what appears to be their harvested organs.

This slot’s 5-reel grid can expand up to 20 rows and 108 ways to win, thanks to the studio’s innovative mechanics and features, including xWays and xNudge. Get creepy with Lobotomy free spins and Autopsy free spins that feature sticky wilds and multipliers and reap amazing modifiers with the ghoulish Enhancer Cells. There’s a top possible prize per spin of 66 666x your bet on the line, so facing the horror could be worth it.

If you have the kind of mind that thrives on psychological thrillers, jumpscares, and body horror, this game will be just your cup of tea. As far as gameplay goes, intermediary knowledge of slot mechanics would be an advantage, so it might not be the ideal starting point for some new players.

5. Paranormal Activity

When the movie Paranormal Activity debuted in 2007, it changed the face of the horror film genre with its striking found footage style. Nine years later, iSoftBet released their online slot interpretation of the film and its brooding, menacing atmosphere. The slot boasts a 5x3 reel format with 243 ways to win, and eerie neon blue reels with recognizable objects, apparitions, and scenes from the movie as symbols.

Creepy spirit hands randomly reach out to you, enhancing the game’s creepy feeling, and the free spins round conveys the horrors of ghostly possession. Stacked wilds boost your winning chances and a grimly occultic bonus wheel awards you extra spins and instant prizes.

Some people can’t stand the creeping feeling that a ghostly presence might be in the same room as them, but if you’re one of those special types that enjoy the sensation, playing this game in the dark will make your night. There isn’t anything too complex involved in the gameplay, all you have to do is face your fear and keep your eyes fixed on the screen to win big.

6. Immortal Romance Mega Moolah

If you prefer your vampires less bloody and more broody with a touch of love in the air, this may be the game best suited for you. Of course, there isn’t a slots player out there who would not want to win one of online gambling’s biggest prizes, so anyone who wants to claim the Mega Moolah jackpot will enjoy the thrill, although there are alternatively themed versions if Vampires aren’t your style.

7. Ghost Glyph

Explore a haunted mansion in this cartoon-inspired spectral romp with big winning chances. Ghost Glyph by Quickfire. The reels are encrusted with precious gems alongside vibrantly hued urns that hold quirky ghosts with corresponding colours. The 7x7x grid features a cluster pays mechanic and a Tumble mechanic that removes winning clusters, allowing more symbols to appear in their place.

The ghosts that emerge from the urns we mentioned earlier bring with them vital enhancements like wilds, symbol upgrades, symbol removal, and access to the bonus round where you can encounter oversized wild symbols.

This title’s theme is reminiscent of a Saturday morning cartoon, so for anyone who doesn’t like their horror too scary, this would be an ideal fit. Fans of cluster pays slots will also appreciate how the bonus features complement this mechanic and the friendly RTP of 96.18% ensures a balanced experience.

8. Curse of the Werewolf Megaways

Hearing howling on a full moon would make just about anyone shudder as it means a menacing half-wolf, half-human beast could be on the prowl. Pragmatic Play explores the mysteries of lycanthropy in this 6x6 reel slot with an astonishing 46 656 paylines. The feral beast and the game’s supporting characters are rendered in a quirky illustrative style, with an air of mystery surrounding the misty village that forms the backdrop.

9. Day of the Dead

Legendary iGaming studio IGT takes on the Mexican candy skull-encrusted celebration of those who have passed to the world beyond in the 3-reel, 720 payline Day of the Dead.

The cultural, colourful presentation of this title makes it part of a unique sub-genre of the horror slots category, so anyone looking for something different will have a good time here.

10. Highway to Hell

The fabled realm of the underworld where souls go to be tortured for their earthly transgressions is possibly one of the most horrific places to imagine, but when you imagine travelling the road to hell in a roaring 18-wheeler, the prospect seems a bit more exciting. This is the premise of Wazdan’s 2012 classic slot with hell-bound highway insignia and a saucy horned creature acting as some of the game’s symbols.

Wild Symbols expand to fill the entire reel whenever they’re involved in a win, greatly increasing your chances of landing a big win.

Games from over a decade ago don’t pack the visual punch that their modern counterparts do, but some people have an appreciation for classic slots. If you prefer a stripped-down experience with top-winning potential, grab your keys and hit the road.

11. Lost Vegas

The thought of Zombies invading Vegas is thrilling enough, but what if you could choose to play on the side of survivors, or the flesh-eating minions? Microgaming gives you that option in this hilarious game where siding with battle-hardened humans or Elvis costume-clad undead could result in massive wins. The game has 5 reels and 243 paylines, with shifting visual environments depending on which side you choose.

The Blackout Bonus turns out the lights and gives you the chance to trigger the bonus round with a single scatter symbol. The Zombie version of free spins includes wild reels, while the Survivors version delivers extra cash prizes.
