Spruce Hollow Slot Demo by Hammer Head Gaming

Spruce Hollow by Hammer Head Gaming Slot Overview

Spruce Hollow by Hammer Head Gaming unfolds in a moonlit forest, with fog, carved wooden reels and glowing lanterns. Its wild multipliers connect it to The Dog House, but here black cats join a woodland witch and a hound that locks them during free spins.

The locked cats gain +1 to their multipliers after each free spin in which they contribute to a winning line, giving the bonus a compelling progression mechanic. High volatility accompanies a 50,000x maximum win. Explore how the features interact with the free demo on BonusTiime.

Spruce Hollow Slot Features

Black Cats, The Witch, The Hound and the Free Spins all shape Spruce Hollow, while Extra Chance, Howl Spin and the Play A Feature menu give it unusual control over pace and bonus access.

Black Cats

Black cats are the core symbol mechanic. They act as Wild symbols, but they do not replace the Witch, the Hound or the Moon. Each cat carries its own multiplier, from x1 up to x1000, and a winning line sums every cat multiplier in that run.

They also create a separate cat row result when that beats the regular symbol win. Their aura changes with value, and locked cats can keep rising during free spins, which gives the system real progression rather than a simple substitute symbol.

The Witch

The Witch does not score herself: she wins nothing on a line and breaks a run. She lands 2 to 5 cats onto random cells that already show a regular symbol, and each cat arrives with its own multiplier before scoring starts. This makes her a setup mechanic rather than a direct win symbol, and she can reshape several lines at once.

The Hound

The Hound only appears in free spins, and at most one can land on a spin. It barks, locking every cat already on the board in place for the rest of the feature. If no new cat gets locked, the bark becomes a growl, so the mechanic rewards continuing cat drops.

Locked cats stay in their cells while later spins run underneath them. After every free spin where a locked cat sat on a winning line, that cat increases by +1. In the base game, nothing carries over to the next round.

Free Spins

The Moon lands at most once per reel, and 3, 4 or 5 Moons anywhere award 10 free spins in Deep Woods, Witch’s Clearing or Blood Moon Hollow. The feature cannot be retriggered, and the Moon does not appear on its reels. Free spins start with no locked cats, then build from there.

Deep Woods uses 3 Moons and gives fewer cats with more hounds. Witch’s Clearing uses 4 Moons and brings more hounds and the Witch more often. Blood Moon Hollow uses 5 Moons or the Mystery buy, brings the most hounds and the Witch often, and always wins at least 1,000x the base bet.

Extra Chance

Extra Chance stays on until you turn it off. It plays each round at 3x the base bet and gives 5x the chance of the free spins. Every other rule stays the same, so it changes frequency rather than the underlying structure of the slot.

Howl Spin

Howl Spin stays active until you deactivate it. It costs 75x the base bet per round, guarantees a Witch, and can land one or two Witches that each cast 3 to 5 cats. No Hound appears, so cats do not lock and only count for that spin.

Moon symbols can still land during Howl Spin and open the free spins as normal. It cannot run alongside Extra Chance, and it switches off if the balance cannot cover the next round. That makes it a persistent paid mode rather than a one-off buy.

Play A Feature

The feature menu holds five paid modes: Extra Chance and Howl Spin stay on and are charged on every round, while Play A Feature buys one round of Deep Woods, Witch’s Clearing or Mystery. A bought feature arrives on a spin that carries its own Moons, with no line win on that spin, and it then plays exactly as if they had landed.

• Extra Chance: x3 the bet per round; 5x the chance of the free spins, and it stays on until you turn it off.
• Howl Spin: x75 the bet per round; a guaranteed Witch every round, and it stays on until you deactivate it.
• Deep Woods: x100 the bet; 10 free spins of Deep Woods.
• Witch’s Clearing: x500 the bet; starts 10 free spins.
• Mystery: x500 the bet; the Moons are dealt at random, 20% no bonus, 20% Deep Woods, 50% Witch’s Clearing, 10% Blood Moon Hollow.

Spruce Hollow Slot Review

Spruce Hollow leans hard into a moonlit woodland horror look, with black cats, a skeletal witch and a hound built into the action rather than left as decoration. The carved frame and misty forest backdrop give it a clear identity, and the symbols keep that eerie woodland tone throughout.

The real hook is the cat multiplier system, because every cat carries its own value and free spins let those values climb when a locked cat lands on a winning line. That gives the game more texture than a standard wild setup, although the base game still depends on the bonus to unlock its best ideas.

Spruce Hollow offers Howl Spin, Extra Chance and three one-time buys into the free spins, and its 96.00% RTP and 50,000x ceiling hold in every mode.
