Ghostly Hallows: Slot Overview

Hacksaw Gaming collaborator Backseat Gaming has already shown it knows its way around a pirate theme, having previously launched buccaneer-style slots like Pirate Bonanza and Pirate Bonanza 2. While those titles focused on living, breathing sea raiders, Ghostly Hallows leans into the supernatural by putting the undead in the spotlight. As with the original Pirate Bonanza slot, Ghostly Hallows is a scatter pays game that also hinges on a Cannon feature and multipliers to generate its bigger moments. The mechanics aren’t a carbon copy this time around, though, so it’s worth taking a closer look at how it all plays out.

Oddly enough, piracy and the undead pair together like an extra round of rum and next-day misery. You’ll find the combo in books and films, and now again in slots, with Ghostly Hallows joining the list. Beside the reels, a dead-eyed captain stands ready at the cannon, while blue flames flicker in braziers and massive ships loom in an unsettling glow. There are even practical upsides to an undead crew: no meals, no scurvy, and plenty of intimidation when it’s time to board a vessel or raid a town. In slot form, it also looks the part, and although Ghostly Hallows has a light, cartoony edge, Backseat Gaming still creates atmosphere through sombre audio and weighty background visuals.

Ghostly Hallows is a scatter pays slot where a win is formed when 8 or more identical symbols land anywhere across the reels. The play area uses a 6×5 matrix. Players can set their wager from $/€0.10 to $/€50 per spin, and the game offers a theoretical RTP of 96.3% alongside highly volatile behaviour.

There are nine paying symbols in total: 5 gem icons, plus pistols, lamps, chests, and skulls. The biggest possible clusters are 25+ matching symbols, returning 100x to 500x the stake. A tumble mechanic removes winning symbols, then refills the empty spaces as new symbols drop down. If this creates another win, the tumble sequence continues.

Ghostly Hallows: Slot Features

The main addition in Ghostly Hallows is its multiplier-feeding Cannon feature, which can appear in the base game as well as both bonus rounds. Beyond that, players also get four feature buy options.

Cannon Feature

Prior to each spin, up to 5 multipliers can show up behind the grid in random positions. These multipliers range from x2 to x1,024. In the bonus game, at least one multiplier is guaranteed. When a winning cluster lands on a multiplier, that multiplier is removed and collected by the cannon beside the reels, stacking with any multiplier already stored. If a Cannon symbol lands, the stored multiplier is applied to the tumble win. The Cannon symbol only activates when there is both a winning combination and a stored multiplier. If a Cannon symbol fails to activate, any stored multipliers are reset for the next base game spin.

Cannon of the Damned Bonus Game

Landing 3 scatters starts this feature with 10 free spins. The multiplier held in the cannon remains persistent until triggered by a Cannon symbol.

Ghostly Pirate’s Trail Bonus Game

Hitting 4 scatters awards 10 free spins in this mode. Here, the multiplier stored in the cannon is persistent through the entire bonus.

Feature Buys

The feature buy offers four different routes. Choose BonusHunt FeatureSpins for 2x to make each spin 3 times more likely to trigger a bonus game, or go with Cursed FeatureSpins at 50x which guarantee a Cannon symbol will land. Alternatively, you can buy Cannon of the Damned for 100x or Ghostly Pirate’s Trail for 250x the stake.

Ghostly Hallows: Slot Verdict

Ghostly Hallows isn’t a straight continuation, but it clearly shares DNA with Backseat Gaming’s Pirate line. The difference is in the tone: where those games leaned into a more playful, yo-ho-ho vibe, Ghostly Hallows takes the darker, ghostlier route. Not that it’s truly terrifying—its style is still more cartoon than cursed—but the developer has shifted the mood enough to give its refreshed Cannon-and-multiplier setup a different stage to perform on.

The feature behaviour can feel a little intricate. This isn’t a Sugar Rush-style setup where multipliers simply pay out the moment a win lands on them. Yes, multipliers that are revealed can be stored, but you still need a Cannon symbol to actually convert them into value. As a result, multipliers can end up doing nothing in the base game even after being banked—assuming they appear behind the grid at all. That’s why the free spins are appealing, since revealed multipliers remain stored until a Cannon symbol links them to a win. Ghostly Pirate’s Trail improves on this by keeping multipliers stored even after they’ve been used. In testing, that led to a very feast-or-famine flow: long stretches where little happened, followed by sudden stacks of multis that could be fired for a solid hit, though this mainly showed up during the bonus round.

Still, Ghostly Hallows’ top prize is available in every mode, and at 20,000x it’s a meaningful ceiling. The mechanics can come across as slightly gimmick-driven, but when everything lines up, it’s hard to argue with how destructive the Cannon multiplier combo can be once it’s charged and ready to fire.
