Halloween and horror slots are about as original as a pumpkin spice latte in October – most of them dress up in spooky costumes but couldn’t frighten a toddler hopped up on gummy worms. Thankfully, Print Studios (courtesy of Relax Gaming) didn’t get that memo and instead decided to give us a slot that actually feels like it crawled out of your nightmares. Enter Darkness. This one doesn’t wink at you with cartoon bats and goofy pumpkins – it stares directly into your soul and asks if you’re ready to lose it.
In this Darkness slot review, I’ll be dissecting whether the game is more than just a cheap scare-fest or if it’s destined to be the slot equivalent of a B-movie jump scare. And yes, you can play it for free at Casinos.com – because if you’re going to be traumatized, at least don’t pay for it upfront.


Most Halloween slots feel like haunted house knockoffs at a school fair – all rubber masks and plastic cobwebs. But Darkness? Oh, it doesn’t pretend to be scary – it is scary. It’s the kind of slot that doesn’t just take your money – it takes your soul and asks if you'd like to spin again. I haven't been this shaken since that time I found out pumpkin spice is just cinnamon in a wig.
For a slot that looks like it was designed in the pitch-black basement of a haunted monastery, Darkness is surprisingly straightforward once you start spinning. You’re working with five reels, four rows, and 26 paylines – classic enough that even your nan could figure it out (though I wouldn’t recommend letting her play this one unless she’s into satanic rituals). Wins trigger when you land three or more matching symbols across a line, and your bets range from a polite $0.10 up to a chunky $50. There’s even an autospin option if you’d rather sit back and let the machine drag you into the abyss without lifting a finger.
Now, most Halloween slots go for cheap thrills – slap a pumpkin on Big Bass Bonanza, call it spooky, and hope nobody notices it’s the same game in a mask. Darkness, however, actually commits to horror. And I mean commits. At first, the reels are so dimly lit you’d think your monitor had given up the ghost. My advice? Crank your brightness settings unless you enjoy guessing which demon rune just paid you.
Once your eyes adjust, though, it all comes together. The rune-like symbols, ritualistic props, and that unsettling soundtrack combine into a genuinely foreboding atmosphere. It’s one of the few horror slots that actually feels horrific instead of cartoonish. Under the hood, the numbers don’t disappoint either: a high-volatility setup, a very respectable 96.14% RTP, and a maximum win of 20,000x your stake. That’s not just a sweet deal – that’s a deal with the devil. And honestly? I’d sign that contract again.
Those glowing lanterns between the reels aren’t just mood lighting. If a win runs through one, it gets multiplied by the number shown. These little devils were responsible for some of our juiciest payouts.
Every now and then, a slot actually bothers to step out of the cookie-cutter graveyard of mediocrity, and Darkness is one of those rare beasts. Sure, the design is so dark it makes my screen look broken, but beneath the gloom lies gameplay that actually grabs you by the throat. The bonus features aren’t just tacked-on gimmicks – they’re genuinely fun, and when you toss in a maximum win of 20,000x your stake, it feels less like a slot and more like a pact with something unholy.
So, is Darkness worth your time at a top casino? Absolutely. It’s eerie, it’s engaging, and it doesn’t insult your intelligence. Consider this one a rare horror slot that actually delivers, and yes, I’d happily recommend it – though preferably with the lights on.
Ah, yes, the night I risked actual mortal coin. I’d just sold a vintage Ouija board on the dark web for a tidy sum – $50 straight into my casino wallet. Naturally, I funneled it directly into Darkness, because if you’re going to tempt fate, do it with flair.
The first few spins were uneventful – a few rune payouts, a creepy whisper through the walls (might’ve been the plumbing, might’ve been something else). But then I hit the Bonus Buy. $50. All of it. One click. No regrets. The screen darkened like a blackout séance, the pentagram ignited, and the ritual began. Wilds started locking in, reels turning to chaos, and somewhere in the attic, one of the dolls blinked. Lucifer emerged, reels went wild, and when the ritual ended… I was holding $950 and shaking like a man who just saw his reflection in a cursed mirror. Best $50 I ever lost… then won back… then probably lost again on werewolf-themed Megaways.
