#1 Clucking Hell: 6,666x Multipliers

• Developer: BGaming
• Where to Play: Mega Bonanza

I didn’t imagine spending my Halloween playing demon chicken invaders, but here we are. BGaming launched Clucking Hell on October 1, 2025, and though I wasn’t overly amused by its name, its gameplay bought me almost instantly.

The Chick’s belly will randomly erupt into an inverse pentagram, conjuring multipliers on random cells. If you end up with an empty hand, the Chick may get angry at your fate and burn the entire field to ash, giving you a free respin.

On a side note, major symbols portray decapitated animal heads, and the top win sits at 6,666x. If that, along with random eruptions and infernal brimstone, didn’t convince you to play “the” most hellish slot for this Halloween, the burning replicator Pentagrams in the Bonus Round might.

These Replicators are linked, and there’s a chance that the one with the highest multiplier will “replicate” its own multiplier to one of the connected cells. Additionally, all multipliers are sticky for as long as you have any free spins left.

#2 Dead Man’s Drop: 20,000 Max Win

• Developer: Slotmill
• Where to Play: ACE.com

Cutting-edge animations, jump scares, creepy dolls, and downright esoteric graphics don’t even scratch the surface of how dark and spooky Dead Man’s Drop is.

This is a 6×6 video slot with an optimal 96.07% RTP and a generous max win of 20,000x. With such a massive win potential, it doesn’t surprise that the game has very high volatility.

The star of this pirate-themed virtual machine is the Multiplier Wilds feature. Whenever they drop, these wilds will double every win’s value, but that’s not all. They also merge when you connect them, and the potential is really high, like, 1,000x high!

And with every avalanche comes a potential explosion through clusters. Free Spins are also included in the mix to lock the best Wilds on-screen, and then there are the Super Free Spins.

The theme gives a strong Pirates of the Caribbean vibe – the ghostly pirates from the Silent Mary, of course!

#3 Devil’s Finger: 96.4% Max RTP

• Developer: Shady Lady
• Where to Play: Stake.us

Now this is a fine slot from an up-and-coming studio, Shady Lady. Devil’s Finger has all the markings of a proper horror slot – possessed priests and nuns, eldritch monstrosities, an Iron Maiden surrounding the playing field, and Mana packed in bottles of Mountain Dew. It’s as Tenacious D as it can get, only we’re getting a fictional character called Cosmo instead of Jack Black.

You’ll notice four Devil Fingers almost waving from the bottom floor. Once you get to the Bonus Round, one random Finger will move by one cell per turn. Each movement blocks the cell where the Finger landed, but it also increases its reel multiplier.

Bonus features in Devil’s Finger took a page from RPG games – stuff like Heal, Lightning Bolt, Conjure Dragon, Frostbite, and Necromancy all have drastic game-changing effects, along with amazing visuals and cool names.

Heal gives you from 1 to 3 more spins; Lightning Bolt pushes one Finger back by one cell; Dragon will summon up to 5 Wilds at random locations; Frostbite pushes one Finger back by at least 3 positions, while Necromancy upgrades a reel multiplier by up to 5x (also moves the corresponding Finger).

#4 Bill & Coin 2: Mummy Mischief: Thrilling Bonus Features

• Developer: Relax Gaming
• Where to Play: LuckyStake

Bill and Coin, the protagonists of a popular tumbling-reel slot by Relax Gaming, went to Egypt and have awoken an ancient curse. While looting the pyramids, they angered a Mummy, but also stumbled upon tons of long-lost treasures.

The base game has a relaxed environment and is carried by a chill soundtrack, but as soon as you get 3 scatters, the roar of thunder will unearth three choices, allowing you to start the bonus with Sticky Coins, Progressive Multipliers, or book-style Expanding Symbol.

Coins nudge down one cell with each spin, and whenever you win, their initial multipliers may increase. Progressive Multipliers were my go-to, as they allow you to boost all winning combos by up to 500x.

The Book Bonus is a great addition and a nod to countless Egyptian-themed slots with Expanding Symbols, where one random symbol is chosen to cover the reel where it landed.

#5 Gates of the Underworld: Hold & Win Jackpots

• Developer: Penguin King
• Where to Play: Rolla

If your idea of Halloween involves a good dose of Ancient Greek Mythology and a set of five Hold & Win jackpots, you should check out this new game from Penguin King.

It’s called Gates of the Underworld, and it’s a 5×4 slot machine with Grand Jackpots soaring up to 3,000x, all with a 95.73% RTP.

The star of this Halloween show is Hades himself. When the God of the Underworld appears on the reels, he collects all the Coin Prizes of every Golden Coin symbol currently active.

Hades is also present in the Hold & Win feature, which transforms the game to a 6×6 thriller where only the Golden Coin, Hades, and Empty symbols are possible. This is when serious multipliers become possible because up to eight Golden Coin symbols can land on every single spin.

On the visual front, the game looks great. While the Greek Underworld is not your typical Halloween theme, it certainly passes the vibe check.

#6 Mental II: Nightmare Volatility Rating

• Developer: Nolimit City
• Where to Play: RichSweeps

Nolimit City launched the sequel to its ultra-popular Mental slot in March 2025, and I’ve had a hard time getting its otherworldly metal playlist out of my head ever since.

It’s been a while since I’ve played a slot that synergizes graphics and audio so well that it deserves to be mentioned before the actual game features and bonus mechanisms. On top of that, you can win up to 99,999x of your stake per spin, which is 9,999,900 SC at max bet.

The story of a mental asylum catching fire gave me the chills, but what I revealed from the concepts behind available bonus games shook me even more. One bonus feature is literally called “Dead Patients”. If two or more appear together, a random multiplier of up to 9,999x is revealed.

“Enhancer Cells” are the scratch marks below the playing field, and they’re triggered by landing Fire Frames. These cells may reveal Wilds, xSplit (chop symbols into smaller ones), xNudge Wilds (moving wilds), Patients, or xWays (3 symbols of the same kind). There are three Bonus Rounds where the core bonus features gain vastly improved effects.

It’s also worth noting that Mental II (and most Nolimit City slots) has a nightmare volatility rating. The usual scale for variance can’t measure the degrees of unpredictability you’ll encounter as you explore the ashen ruins of the second Mental asylum.

#7 Jack O’ Wild: Classic Halloween Vibe

• Developer: Gamzix
• Where to Play: PlayFame

You can’t have Halloween without Jack O’ Lantern – the scythe-wielding, soul-reaping revenant. While he’s a frequent resident of many classic slots, he recently reared his head in a new Gamzix slot release called Jack O’ Wild.

This is easily one of the simplest spooky-themed games you can play this year. In a nutshell, you’ll have a 4×5 grid with Wilds for the base game, and a few interesting modifiers for the Bonus Game, including Free Spin Multipliers and Guaranteed Wilds.

Best of all, the Bonus Game begins with a Wheel that decides your starting FS count and multiplier (the best outcome is 14 spins with a 100x multiplier).

#8 Klowns: Scariest Theme

• Developer: Hacksaw Gaming
• Where to Play: Casino.click

Heads up – this slot is not for individuals who have any symptoms of coulrophobia. Klowns wears its IT influence on its sleeve, and unlike some subtler spooky games in Hacksaw’s catalog (like Booze Bash), this slot growls horror from the outset. The symbols flying upward like balloons give Klowns an extra layer of spookiness, while Pentagrams, Anarchy, and Dead-eye symbols further reinforce its scary elements.

Regarding the specifications, Klowns boasts a good RTP of 96.26% and allows you to win up to 10,000x per round. Like most Hacksaw-made slots, Klowns is stacked with numerous bonuses, some of which even appear in the base game.

Needle Boxes can be game changers. The ones with a purple background remove the shown group of minor symbols, while boxes with a red background clear major symbols and instantly pay 0.3x of your current bet per symbol. During the Bonus Games, you’ll see Klown Multipliers with values of up to 500x, Multiplying Multipliers of up to 20x, and stacking multipliers that can be unlocked with Needle Boxes.

#9 Zombie the Apocalypse: Exciting Bonus Round

• Developer: Playzia
• Where to Play: Fortune Coins

There’s hardly a zombie-themed slot with more complex bonus features than Playzia’s Zombie the Apocalypse. Three unique scatters, each triggering a separate bonus feature, Hold & Win, two bonus fields, and a bet range that accepts stakes of up to 250 SC are just some of the reasons I love playing this game, even after Halloween’s passed.

Zombie Clash is the highlight feature for me. It basically simulates a Mortal Kombat-style fight between a survivor and a zombie, where their health bars are measured in multipliers instead of actual HP points. Once the Clash ends, the remaining multiplier of whoever’s left standing is applied to your bet as an instant prize.

Bag 3 or more Hazard scatters to trigger a nuclear apocalypse that is the Bonus Round. This is where you’ll find three types of barrels – green ones upgrade multipliers; red barrels trigger two Hold & Win fields and start with a 2x multiplier, while purple barrels reset your re-spins to 4 (instead of 3) and apply a 3x multiplier.

#10 Booze Bash: Loads of Multipliers

• Developer: Hacksaw Gaming
• Where to Play: Jumbo88

At first glance, Booze Bash might not scream Halloween, but stick around for the bonus rounds, and the festive chaos turns downright spooky. Whether you trigger it by landing a pair of scatters or jumping straight in with the bonus buy, that’s when the masks come off and the creepy side kicks in. The game was released by Hacksaw Gaming in June 2025, and is among the freshest spooky slots you can play this Halloween.

One of the best features of this slot is that all symbols may feature multipliers from 2x to 20x. Moreover, there are two bonus rounds, each with a different set of special triggers. The Guilty As Sin round requires just one pair of scatters and improves the spawn rate of major symbols. Top-Shelf Trouble morphs the Imp into a full-fledged demon, but it also adds an extra reel where you’ll either find paying or “dead” (void) symbols.

This slot is different from all of my earlier recommendations in this guide, mainly because it uses the innovative “pairing” mechanism instead of traditional paylines. Apart from hitting a different note than most classic Halloween slots, I recommend Booze Bash because it offers a super-high top win potential of up to 12,500x.
