Hot

Mental

We’ll start the list with one of the most hardcore slots of all time. Despite being released a few years ago, NoLimit City’s Mental slot game has proven itself one of the most innovative horror-themed slots.

It’s all because of NLC’s amazing vision. The studio has turned into one of the most distinct developers on the market, known for the range of themes and one-of-a-kind unique features.

Mental Slot Machine

Mental slot machine packs all of that in a spine-chilling adventure through the halls of a mental hospital. The slot’s atmosphere is as unique as it gets.

You’ll constantly be looking over your shoulder thanks to the brooding soundtrack and those spooky sound effects. It has NoLimit City’s fingers all over it, with 180 expanding win ways, xWays, xNudges, and xSplits.

You’ll see very disturbing imagery on the reels, with mental patients that don’t have your best interests at heart. The features themselves are scary as hell.

You have Mental Transform which turns into xWay symbols, including a dead patient or patient premium symbol. The bonus rounds include Lobotomy, Autopsy, and Mental free spins, triggered by a combination of scorpions and scatters.

It’s a skin-crawling atmosphere like no other, and one of the scariest slots you can try. Well, if you dare.

Possessed

Possessed is another slot from the brilliant minds at NoLimit City. We’d certainly like to know what’s going on in their minds when they pick themes and lay the story elements and gameplay out.

Possessed slot game is a fantastic homage to exorcism movies in the scariest possible way. Seriously, this thing could pass for a new Exorcist movie – the last release didn’t pan out at all anyway.

Possessed slot demo

The action takes place on an expanded 5×3 grid. When we say expanded, that’s because you get 3 rows on the first and last reel, and 6 on the middle reels. And yes, that layout forms an inverted cross.

The possessed girl is in the center of it all, with her poor praying mother and the weak priest among the symbols too. There’s a demon and a black cat to complete the dark picture.

In terms of features, this slot features NLC’s unique xWays, xWilds, xActivation respins, and Infectious xWays that can spread to neighboring symbols.

Burning bible scatters aptly trigger the bonus round, where you get Atonement, Beelzebub, or Necromancy spins. Each one of them is unique in their own way, and of course, offer nail-biting action.

Just for your sake, we’d keep a glass of Holy Water nearby – you never know when something can jump out of the screen. That’s how real the Possessed slot is.

Reel Fear

If you’re a fan of the Silent Hill video game series, you’ll love what Reel Fear has to offer. This popular slot was developed by Booming Games, and has a lot to share with the Konami classic, despite the fact it’s not a branded title. There may be no Pyramid Head, but the spooky nurses and a bloody rabbit toy make the cut.

Reel Fear

Reel Fear slot machine follows a simple and mostly classic approach. It has a medium to highly volatile math model with 10 paylines. Line the spooky symbols up on the lines for a win. The disturbing kid is the wild, substituting for all symbols in win combos except for the even spookier rabbit toy.

Land three of those rabbits for a nice scatter win and entry into the bonus round. It plays like the base game, but you’re not paying for the spins. The spooky atmosphere and down-to-Earth approach—even if it’s set in another realm—make Reel Fear a perfect pick for slot fans.

Dark Summoning

Dark Summoning is a reel treat for fans of hellish horror themes. It takes place deep in the underworld, with the Grim Reaper and devil himself flanking both reels.

Developed by Hacksaw Gaming, what makes this slot a great choice for horror fans is the aesthetic. It literally looks and feels like it’s set in Hell, and to make things even more devilish, the max. win is set at 10,666x the bet.

Dark Summoning video slot

Dark Summoning slot machine features a unique atmosphere, with the sights and sounds of hell providing the perfect setting. It has 24 paylines, with an innovative super-cascade mechanism triggering on every win.

Symbols pay in the most standard way. You need three or more from left to right to hit a win. The symbols include Baphomet, Illuminati pyramids, flies, crowns, and scissors, all designed in a fitting way.

Super-cascades remove winning symbols from the grid. All winning symbols are marked, and blue and red wilds can land with a multiplier up to x100 for a hellish boost to wins. The Unholy symbol is collected when part of a win, which could possibly trigger the bonus rounds.

The Trial by Hellfire and Rise of Salvation free spins come with special mechanics. In the former, all marked positions are turned to wilds after wins. The latter brings an inverted cascading mechanic, with symbols moving up instead of down, offering an even better winning potential than the base game.

It’s an unholy slot itself, and one that will certainly delight any fans of the Devil or the occult.

Jekyll & Hyde

There’s no horror genre without the brilliant novel Jekyll & Hyde by Robert Louis Stevenson. It’s the pillar of the gothic horror genre, so it naturally slots right in within the slot industry.

Jekyll & Hyde slot game by Microgaming is one of the many slots based on this theme. Microgaming’s version comes with a medium variance math model and 243 ways to win, paired with a brilliant gothic horror atmosphere.

Jekyll & Hyde

The slot follows a simple, yet effective formula. Wins are formed for three or more matching symbols in adjacent positions, with wilds substituting for other symbols in all win combos. Scatters pay in any position and trigger the all-important bonus round.

As expected, the bonus brings the duality of the main character into focus. All Dr. Jekyll symbols transform into Mr. Hyde, in that way boosting your winning chances. My. Hyde symbols pay more than any other in the free spins round, making this gothic horror bonanza a must-play.

House of Doom

House of Doom is widely hailed as one of the best horror-themed slots of all time. On the surface, it doesn’t look out of the ordinary. You have a medium variance math model with 10 pay-lines, but it’s the expanding symbol in the bonus round that makes it worth your while.

House of Doom

The unique visuals look like they’ve been ripped out of a comic book. The main character, the so-called Seer, expands to cover two or more of the slot’s reels in the bonus round. House of Wild doom symbols can also appear, granting you extra spins as you descend into the Skulls of Abyss bonus

Select skulls to reveal House of Doom symbols or pick again with the corresponding coins. This is where you get close to the ancient mysteries, with wins up to 2,500x at stake.

Folsom Prison

We’re back with yet another NoLimit City slot. The developer’s innovative ideas are full on display in Folsom Prison, a slot with up to 46,664 ways to win.

Now, this might not be a slot based on the supernatural, but it does feature a much more grounded and scary experience where you’ll be locked in with supermax prisoners in a notorious prison.

Folsom Prison slot demo

You have 16 original ways to win, with many of the symbols behind bars on the grid. Only a small part of the grid is unlocked, while other positions remain locked.

Hitting wins with matching symbols outside the grid increases the number of winning ways. So do the xWays, xSplit, and xWild symbols, all of which can increase your winning chances.

The base game itself is exciting and rewarding, but it gets even better in the bonus round. You’re guaranteed one out of three so-called cockroach nests in the bonus rounds.

Cockroaches can go anywhere in this prison, and their nest always spawns on the central reels. Upgrades can also happen, either upgrading cockroaches or the multiplier for bigger wins.

The hardcore prisoners look quite rowdy in this grounded and scary adventure. We wouldn’t be like to be locked in with these prisoners, just as we wouldn’t be like to be locked inside a haunted house.

Origins of Lilith

Spinomenal’s Origins of Lilith is based on one of the many mysterious Mesopotamian figures. Lilith is a primordial she-demon who’s reportedly banished from the Garden of Eden for not complying with Adam’s rules.

You can learn more about her in Origins of Lilith slot machine, a highly volatile slot with 25 pay-lines.

Origins of Lilith slot machine

The slot’s unique art style and the dark visuals make it a favorite for fans of horror. Lilith herself looks like a mysterious seductress. Siding with her may not bring anyone a lot of good. Landing her is great, though, as she’s a stacked wild that can help create better wins.

Land three scatters to reach the bonus round. A single spin on a bonus wheel will determine how many free spins you get, and you can land up to 40.

During free spins, the cup always lands as a double symbol, doubling your chances to hit big wins. It may not be the scariest slot, but the dedication to the she-demon and excellent aesthetics make Origins of Lilith one of the top horror slot games you can try.

The Curious Cabinet

Open the doors to the curious cabinet and you’ll find ancient and possibly haunted relics. The Iron Dog Studios slot game comes with many surprises, including an obsessed doll on the splash screen that looks like Annabelle.

The Curious Cabinet slot game

A medium volatile slot, The Curious Cabinet slot game has 40 winning lines. Its symbols include Tarot cards and all kinds of monsters, skulls, and mysterious potions, all of which offer amazing returns.

Sticky Wilds can provide guaranteed wins, and the silver drawers in the bonus round come with x2 multiplier wilds. If you’re in for a world of haunted paintings, demon dolls, and big wins, The Curious Cabinet slot machine is the perfect pick.

Immortal Romance 2

Immortal Romance 2 is a sequel to Games Global’s classic gothic horror slotImmortal Romance.  The sequel retains the 243 winning ways of the original, while bringing back the fan-favorite characters.

They all come with their own bonus round once again, but instead of re-triggers, you can now choose the bonus you want to play.

Immortal Romance 2 slot demo

A highly volatile slot game, the vampire saga comes with rolling reels, character jackpots, and of course, four distinct free spins modes. It takes everything great about the classic and boosts it with new features and higher payout potential in one of the top horror slots of all time.

If you loved the original gothic horror bonanza, you’ll love this one too. With better aesthetics and better winning potential, it will appeal to all vampire fans.
