This one by ELK Studios is a high-volatility, horror-themed slot that drags you into a nightmarish underworld of splitting symbols, growing multipliers, and shifting Wilds. Our Nightmaker slot review will focus on this 5x5 slot, built for fans of the grim and gothic, with visuals straight out of an H.R. Giger fever dream. The 3-5-5-5-3 grid layout starts with 1,125 ways to win, but that can expand all the way to 25,000 thanks to symbol splits and corner unlocks. This is not a light-hearted cartoon slot. The atmosphere is thick with dread, the sound design is haunting, and the mechanics are wild. Big symbols. Jumping Wilds. Beast Spins. A Super Bonus mode that escalates quickly. If you like controlled chaos with monstrous payout potential, Nightmaker does the job.
Nightmaker runs on a highly volatile engine, packing aggressive mechanics and unpredictable swings. The game’s RTP sits at 94%, which is below average by most standards. This is standard fare for ELK Studios, but players should be aware that it increases the house edge compared to 96% slot games.
Wagering starts at £0.20 and caps at £100 per spin. The base layout is 3-5-5-5-3, which delivers 1,125 ways to win by default. This increases to 3,125 ways when the four corner tiles are unlocked and can expand all the way up to 25,000 paylines thanks to symbol splitting.
There are no ante bets or adjustable volatility settings. However, the game does include the X-iter feature, which offers multiple paid bonus entry modes—ranging from bonus hunts to instant Beast Spins—at fixed costs between 3x and 500x the base stake.
The max win potential sits at a terrifying 50,000x your bet. And no, this is not tied to a jackpot. It is raw symbol-generated output, likely during a beastly combination of big symbols, split multipliers, and corner-linked Beast Spins.

Nightmaker ditches ELK’s usual cartoonish charm in favour of something dark, moody, and genuinely unsettling. The reels are framed inside a grotesque tunnel of ridged bone-like structures—more Alien than Aloha Cluster Pays. It feels like someone at ELK raided H.R. Giger’s sketchbook after a nightmare.
The background audio plays like a war requiem. Soft, sinister music underscores the sense of decay and dread, with subtle wind howls, ticking clocks, and distant whispers. This is not just horror-themed, it is elegantly grim.
The grid features five columns, laid out in a 3-5-5-5-3 pattern, with a sixth Feature Row hovering above. That row activates column-based features like Wildfire, Symbol Multipliers, and Wild Spirit when triggered.
Here is the breakdown of symbols:
The real visual punch comes from Big Symbols. These can appear on the central 3 reels as massive 3x5 images, splitting into 15 mini-symbols and expanding the win potential dramatically.
Nightmaker’s audio-visual identity is a dramatic shift from ELK’s usual offerings, and frankly, it works. It is one of the studio’s most striking designs to date. It is eerie, bold, and never boring.
Here is the paytable:
Glyph 1
3 = 0.1x stake / 4 = 0.2x stake / 5 = 0.4x stake
Glyph 2
3 = 0.1x stake / 4 = 0.2x stake / 5 = 0.4x stake
Glyph 3
3 = 0.1x stake / 4 = 0.2x stake / 5 = 0.4x stake
Glyph 4
3 = 0.1x stake / 4 = 0.2x stake / 5 = 0.4x stake
Bone Fragment
3 = 0.2x stake / 4 = 0.4x stake / 5 = 0.8x stake
Purple Orb
3 = 0.6x stake / 4 = 0.8x stake / 5 = 2x stake
Skull or Demon Face
3 = 1x stake / 4 = 2x stake / 5 = 10x stake
Nightmaker is fully optimised for mobile play, with smooth scaling across all screen sizes and platforms. Despite its complex grid (3-5-5-5-3 layout with a feature row and expanding mechanics), the interface remains crisp and readable on smaller devices. Symbols resize intelligently, and the cascades plus feature triggers remain easy to follow even during hectic bonus rounds.
We tested the game on both Android and iOS. Gameplay was consistent, with no frame drops or lag during animations. Swipes and taps are responsive, the spin button is well-placed for both thumbs, and the X-iter menu is accessible without being intrusive.
The only minor drawback is that the sheer amount of motion (cascading reels, animated multipliers, and shifting Wilds) can be a lot to process on a smaller screen. But if you are used to high-action slots like San Quentin or Tombstone RIP, you will feel right at home.
Nightmaker is packed with layered mechanics that interact in unpredictable, but often rewarding ways. This is not a simple free spins-and-Wilds slot. This is closer to a slot sandbox, where symbols split, multiply, and detonate in chaos.
Here is a complete breakdown:
Every winning combo triggers a cascade. Winning symbols are removed, new symbols fall from above, and Wilds shift down. Cascades continue as long as wins are created. Used feature symbols in the Feature Row also respin.
These are massive 3x5 versions of the regular pay symbols that appear on the middle three reels. When triggered, they split into 15 individual 1x1 symbols, dramatically increasing win potential.
Big Symbols are often triggered by the Rattle Feature, which can randomly drop 1 to 3 big symbols at the start of any spin. All column-based bonuses from the Feature Row still apply when big symbols land.
The top Feature Row affects the column below it when activated. There are four modifiers here:
Triggered by landing 3 Scatter symbols, the bonus game gives 8 free spins. One random pay symbol is selected to receive a persistent multiplier for the duration of the round.
During the bonus game:
If one of the 3 triggering Scatters is a Super Scatter, you unlock the Super Bonus instead. This introduces a Jumping Wild—a wild that moves to a new position between each spin and after every win. It temporarily adopts the multiplier of whatever symbol it lands on.
You can earn extra Jumping Wilds if a Super Scatter lands in a corner during either bonus mode. This creates multiple Wilds bouncing around the grid. Absolute chaos.
Unlocked when Scatters land in all four corners during the bonus game. During Beast Spins:
Beast Spins are where the slot’s 50,000x potential becomes realistic—especially when split symbols, high-value symbols, and Jumping Wilds combine.
Nightmaker includes X-iter, ELK’s trademark bonus buy system. Here are the available modes:
I will not lie—the first few spins of Nightmaker left me disoriented. Wilds were jumping, symbols were splitting, multipliers were ticking up, and a skull stared at me like I owed it money. But once the mechanics settled, this became one of the most entertaining ELK slots I have played in a while.
Yes, the 94% RTP is a drag. Yes, the base game can be quiet at times. But when this game wakes up, it really wakes up.
Big Symbols splitting into armies of pay symbols, Jumping Wilds bouncing around like caffeinated gremlins, Wildfires engulfing entire columns. It is a lot, but it works.
It is not perfect. I think ELK pushed the visuals and mechanics right up to the edge, and some players may find it too overwhelming. But if you like the darker end of the volatility spectrum and want a slot that does not play it safe, Nightmaker delivers. Think Dreadworks meets Nolimit City with a side of fever dream.
Nightmaker is ELK Studios at their most experimental. Bold, dark, and refreshingly chaotic. The 94% RTP will put off some, but the layered bonus mechanics, huge symbol splits, and beastly max win potential make up for it. It is not for everyone, but for high-volatility chasers, this is a treat.
