Reels/Paylines: 5 reels + 26 Paylines

Stakes Range: 10p to £50

Max Win: 20,000 x stake per spin

RTP:  96.14%

The Darkness slot takes place on a 5 reels and 4 rows, with 26 fixed paylines. To create a winning combination, simply land 3 or more matching symbols on adjacent reels, from left to right, along a payline.

You can play the slot from as little as 10p up to £50 per spin. To adjust your stake, just use the arrow buttons above the main spin button. There is also a Feature Bet option which increases your bet by 50%. Well talk more about this later.

Outside of the UK, you’ll find an Autoplay button below the reels. You can use this to spin up to 1,000 times without clicking, but do note that you cannot set win/loss limits. As this game has a high volatility, use this feature with caution.

Darkness has an RTP rate of 96.14%, which is just above the average for online slots and in line with other Print Studio slots too. The game also has a generous hit frequency of 33%, which means that on average every third spin will create a win.

Finally, the slot offers maximum wins of 20,000 x your stake per spin. Bigger wins come via the Free Spins round, where features work together to boost payouts.

Theme – dark rituals bring the supernatural to life

Theme: The Occult

High Value Symbol: Agatha/Wild

Compatibility: Mobile, Tablet, Desktop


The Darkness slot is, naturally, very dark. With superb graphics, it explores the occult, putting a unique spin on the classic Halloween slot theme. Set in an abandoned house, it appears a supernatural ritual has gone wrong, leaving a trail of skeletons behind and summoning witches.

Before the game begins, players are invited to adjust the brightness of the game. We recommend keeping things rather shadowy, however. The idea was born from Print Studios’ CEO Carl Wiggman. He was inspired by the weird world we step into when we get up in the middle of the night.

The slot has a cinematic feel, and the contrast between the dark setting and the other graphics are a big part of this. It’s like watching a horror film, waiting for things to pop out and make you jump.

On the reels, lower-paying symbols include various Wiccan twigs. The middle of the paytable includes daggers, vials, and chalices, whilst the two witches are the higher paying symbols. Agatha, the ghostly pale witch, is the highest paying regular symbol. She rewards you with 25 x your bet for a 5-of-a-kind combination.

The Darkness slot also boasts a Dirge Wild symbol, which pays 50 x the bet for a 5-of-a-kind combination and substitutes for all regular symbols. Pentagram scatter symbols can also land anywhere to the reels and 3+ triggers Free Spins.

Darkness mobile


The Darkness slot uses HTML5 technology to bring the creepy experience to the smaller screen. As such, you can the title on desktop, tablet, and mobile casinos. It performs perfectly on both iOS and Android smartphones.

Darkness Bonus Features

The Darkness slot boasts 3 main bonus features, plus a bonus buy option for players outside of the UK. This includes Print Studio’s popular SuperSpinners mechanism, giant symbols, and the Dark Ritual free spins feature.

SuperSpinners Feature

In both the base game and free spins, you’ll find lanterns displaying numbers nestled between the reels. This is the SuperSpinners mechanic, which can also be found in other Print Studios slots such as Cash Defense and Holy Hand Grenade.

There are 14 SuperSpinners, which trigger at random. Winning combinations that cross these positions are multiplied by the value shown on the SuperSpinner. If a winning combination crosses more than one SuperSpinner, it will be multiplied one by one. This can lead to big payouts!

Giant Symbols Feature

Giant symbols may land randomly on any spin. These can be between 3×2 and 4×5 in size, and all positions covered by a giant symbol count as instances of the selected symbol.

Free Spins Feature


Land 3 or more pentagram scatters in the base game to start the Dark Ritual Free Spins feature. Collecting 3, 4 or 5 scatters initially will give you 10, 12 or 14 free spins respectively.

During the round, a pentagram overlay appears on the reels. Land a wild symbol on the points of the pentagram and it turns sticky. This means the wild remains in place until 5 wilds land on all pentagram points.

Once you fill the pentagram, you summon Lucifer. This is a visually stunning (and scary) feature which also turns reels 2, 3, and 4 wild for the remainder of the round.

Buy Bonus Feature

Like many new slots, Darkness comes with a Bonus Buy feature. Do note, however, that due to regulations this feature is not available at UK slot sites.

Players from outside of the UK, however, have two options:

  • Scatter Boost – Costs an additional 50% of the current bet. Increase the chance of triggering the bonus round from 1 in 300.38 to 1 in 122.19 spins.
  • Free Spins – Grants immediate entry to Free Spins feature at a cost of 100 x your current bet. RTP rises to 96.79%.

Print Studios describe the Darkness slot as a one of a kind experience that will both scare and delight the living daylights out of players’. When we read this, we were somewhat sceptical. We’ve played a lot of Halloween slots that are more childish than chilling, however, we’ve been gladly proven wrong.

The Darkness slot is visually fantastic and also terrifying. The graphics are completely innovative, putting you on edge from the get-go. What’s more, the impressive nature of this slot is not only superficial.

The base game is enjoyable, with SuperSpinners and giant symbols helping to boost your wins. That said, the free spins round is the most exciting. Here, the features all stack together, with the addition of wild reels, to give you a good shot at reaching those 20,000 x bet max wins.

Overall, Darkness is a triumph. If you dare give it a spin, you’re rewarded with solid gameplay and a truly unique design. It’s one of the spookiest releases we’ve come across – be brave, give it a go yourself.

Got a sadistic pleasure for unnerving slots? Try Serial and True Kult. Arguably the kings of creepy slots, Nolimit City bolsters these games with 74,800 and 23,237 x max wins, respectively. There are also plenty of bonus features to enjoy.

  • 20,000 x bet max wins
  • Truly unique and innovative design
  • Great array of bonus features
  • Highly volatile
  • Theme won't be for everyone
