Dark Spiral Slot Review

The Dark Spiral Slot Game

This video slot comes fresh from Hacksaw Gaming’s kitchen. Typical of the studio’s creations, it steers clear of the predictable and embraces the bizarre world. Therefore, don’t expect a friendly scene. Instead, the slot’s design looks like a surrealist artist with a soft spot for Lovecraftian horror designed it.

A 6 by 4 gameboard bordered by ropes floats against a backdrop of swirling darkness. A bunch of female characters sit by the Dark Spiral reels, with their eyes glued to the action. There’s no doubt you’re entering a disturbing scene because even the ambient tones and warped sound effects give the impression you’re tuning into something very wrong.

The game’s interface is lean, with control buttons lined up at the bottom of the screen. They’re all responsive, enhancing smooth and effortless navigation.

Symbols and Payouts

The symbols are where everything nightmarish comes to life, thanks to the distorted anatomy and void-born shapes that complete part of the paytable. In total, the game features 10 regular symbols and is engineered on up to 331,776 ways to win!

You win when matching symbols appear on 3+ adjacent reels from left to right, starting from the leftmost side. After every win in Dark Spiral, the winning symbols are removed, and new ones drop in. The cascades continue as long as new winning combinations occur.

The bottom of the paytable comprises the 10 through to A royals, and they pay 0.2x to 0.5x the bet for 3+ of the same. Then, the upper section includes:

• Tied Arm and Centipede with Eyes: 0.3x, 0.5x, 0.7x, and 1x the bet.
• Upside-Down Person and Child Swallowing Worms: 0.5x, 0.7x, 1x, and 1.5x the stake.
• Bloody Eye: 1x, 1.5x, 2x, and 3x the bet.

There’s a wild symbol, which substitutes for all the regular symbols. It also pays 5x the bet for 6 wilds that complete a combination.     

Dark Spiral Slot Bonus Features

The main attraction has to be the Summoning symbols, accompanied by three bonus rounds and feature buys.

Summoning Symbols

The Summoning symbols in Dark Spiral can land in 1x2, 1x3, and 1x4 configurations. Whenever they land, they all reveal a different stack of the same paying or wild symbol. A 1x2 Summoning symbol reveals 3-6 symbol stacks, a 1x3 reveals 5-9 stacks, and a 1x4 reveals 6-12 stacks.

If a wild symbol lands directly above or below a Summoning symbol on the same column, the Summoning symbol will increase in size by expanding to cover that wild after the grid settles. When Summoning symbols form a win, they’re not removed as part of a cascade. The winning Summoning symbols reveal a new paying or wild symbol until no new wins occur.

Shattered Bonus Game

Land 3 FS scatters simultaneously in the base game to trigger 10 free spins of this bonus that keep the base game mechanics. Furthermore, it has an increased chance of landing Summoning symbols. Land 2 or 3+ FS symbols in this and all other bonus rounds to receive +2 and +4 free spins, respectively.

Twisted Bonus Game

Manage 4 FS scatters in the Dark Spiral base game to trigger 10 free spins of this bonus that retains the Shattered bonus mechanics. Additionally, all Summoning symbols that land will be sticky throughout the bonus and reveal new stacks with paying or wild symbols when part of a win on every spin.

Hidden Epic Bonus - Tortured

Land 5 FS scatters in the base game to start this bonus, worth 10 free spins that keep the Twisted bonus mechanics. In addition, it guarantees 2 Summoning symbols on the initial spin.

Bonus Buy

This video slot lets players buy the following features from the base game:

• BonusHunt FeatureSpins: For 3x the bet, each spin is 5 times more likely to trigger a bonus.

• Summon the FeatureSpins: For 100x the bet, each spin guarantees at least 2 Summoning symbols.

• Shattered: Bonus for 100x the stake.

• Twisted: Bonus for 200x the bet.

How to Win at Dark Spiral Slot

Like many modern slots, this game doesn’t conform to classic paylines. Instead, its 6x4 reelset pays through 331,776 ways to win! Therefore, wins are formed whenever you manage 3 or more identical symbols on consecutive reels from left to right, starting from the leftmost side.

The Dark Spiral wins trigger cascades, removing all the winning symbols and replacing them with new ones from above. The cascades keep every spin in motion until no more wins occur.

The stakes here range from a modest €0.10 to a full-throttle €100 per spin, making it ideal for playing poking the void or diving in headfirst. After picking a comfortable amount, press the spin button or push the spacebar to gamble a single game round.

This video slot also features an Autoplay feature that lets you preselect and set multiple spins to start automatically.

Dark Spiral Slot RTP & Volatility

This slot’s base RTP is a precise 96.22%, though it can change when you use the bonus buy options. Meanwhile, the volatility is high (4 out of 5 on Hacksaw’s scale), and the top win is 10,000 times the bet. 

Concluding Thoughts

Most slot enthusiasts would rather spin somewhere warm, colourful, and reassuring, not in a dimension where mirrors lie, and anatomy refuses to behave. Yet, embracing horror or scary-themed slots is like swimming against the current. That’s how Hacksaw Gaming convinces players to subscribe to their dark releases.

Dark Spiral clearly doesn’t mind that uphill swim, as it’s unapologetically grim, uncomfortable, and deliberately scary. In fact, it’s so committed to its grim worldview that even a small win feels like it’s been dragged out of something that didn’t want to let go, like in Dreadworks. So, if you prefer warmth, colour, and reassurance, this game will feel like deliberately choosing the wrong door.

The gameplay does a lot of making up, starting with the 331,776 ways that keep spins fluid, to the genuinely clever Summoning symbols and the three-tier bonus rounds. The wide betting range and 10,000x bet win cap are also hard to ignore.

That said, the high volatility can be punishing, and some feature buys feel priced more like dares than options. So, is it worth playing? Well, it depends on how comfortable you are with this “bad idea”. And if you feel you’re bold enough to face the grim world, you’re welcome to go for it.
