Bone Howl Online Video Slot

Bone Howl slot gameplay screenshot

Bone Howl takes you down into a torch-lit dungeon of crumbling stone arches. A cartoon skeleton in a purple hood grins from beside the spin button, skull bolts stud the frame, and the green slime of the logo drips over the reels. On my very first screen, two full-height Skeleton Wilds towered over reels 1 and 3, tagged x1024 and x2048. I played at 1.00 with a 1,000 balance.

Quick take: A 5×4 payline slot where the Skeleton Wild is the only wild and every one carries its own win multiplier. Three or more Bonus symbols trigger free spins with far more wilds, and in the Super Bonus each arriving wild turns sticky until the end.

Theme and Gameplay

The symbols are a dungeon crawler’s inventory: a zombie hand, a rusty skeleton key, green poison potions, round wooden shields, a tattered red banner with a skull, an empty glass bottle and, cheekily, a 50% Off coupon. Gold coins stamped Bonus with a little skull are the scatters.

The Skeleton Wild is a spine of bones crowned by a red skull and wrapped in dark blue mist, and its multiplier is printed in bright blue beneath it.

Slot Features

Skeleton Wilds may show up on all five reels and cover every icon apart from Bonus coins. When it completes a payline, that line’s win is multiplied by the wild’s value, and when several Skeleton Wilds share one line win, their values combine before the win is multiplied. That rule applies to regular spins and both bonuses alike.

Three or more Bonus coins anywhere unlock free spins. The Normal Bonus keeps the usual reels and paylines, but Skeleton Wilds turn up far more frequently, each bringing a personal multiplier.

The Super Bonus follows the same rules with one big difference: each Skeleton Wild that arrives sticks until the bonus ends, so the reels slowly fill with multiplier wilds round by round.

Feature focus: Stacking multipliers is the dream. Because every wild value on a winning line gets summed, two or three Skeleton Wilds on the same line can multiply a win many times over, especially once they start sticking in the Super Bonus.

RTP and Win Potential

The feature shop holds a mode that improves the bonus trigger rate each spin, plus direct buys for both the Normal and Super versions.

Given wild multipliers in the four-figure range I saw on screen, volatility is high, and single spins can swing dramatically.

My Thoughts On This Slot

I like how bold the central idea is. A single wild type that always carries a multiplier keeps every spin interesting, and the sticky wilds of the Super Bonus build tension nicely. The cartoon dungeon art strikes a fun balance between spooky and silly.

Beyond the wilds there isn’t much variety, though, and ordinary rounds can feel repetitive between big hits.

Final Take: Bone Howl is a punchy, focused slot built around one great feature: multiplier wilds that can become sticky. Anyone who likes simple rules with explosive potential ought to try it.
