Gem Ghosts: Slot Overview
Hacksaw Gaming partner Bullshark Games digs into the ever-popular mining genre with Gem Ghosts, a slot that swaps out mortal miners for a cast of playful spectres. Mining is one of the most saturated themes in iGaming, so the decision to fill the tunnels with cartoonish ghosts instead of people is a creative attempt at carving out some individuality. Even more distinctive is the bonus feature, built around a collect phase where players gather wild multipliers before unleashing them all in a single free spin—one that can retrigger and potentially deliver a huge hit.
The base game sets the scene with a bespectacled, bearded miner ghost floating alongside the reels, while a skeleton companion lounges next to a gem-packed cart. Trigger the bonus, and the action shifts deeper into a cavern brimming with jewels and spectral characters. Despite its ghostly cast, the presentation is more Casper than creepy, making the real scare factor the math model beneath. While mining slots are nothing new, ghostly miners are a fresher twist, helping Gem Ghosts stand out—at least thematically—amidst a crowded genre.
Gem Ghosts – Gameplay & Symbols
Gem Ghosts plays out on a 6×6 cluster pays grid, where wins occur when 5 or more identical symbols connect orthogonally. Each cluster win activates cascades—winning symbols disappear, new ones drop in, and the process continues until no fresh clusters appear. Players can spice up the action with several feature bet options, while standard stakes range from €0.10 to €75 per spin. The slot runs on two RTP models, with the highest set at 96.24%, and offers extreme volatility rated 5/5 for a high-risk, high-reward experience.
The paytable lists ten regular symbols: 10–A card royals, shovels, picks, lamps, helmets, and gem carts. Payouts range from 0.1x to 1x the bet for 5-symbol clusters, climbing to 10x–150x for clusters of 27 or more. Wilds substitute for all regular symbols and share the same payout value as gem carts. Wilds can also carry multipliers from x2 to x100, which apply to any win they’re part of, ramping up the potential for massive hits.
Gem Ghosts – Features
Bullshark packs Gem Ghosts with several spooky extras, including respins, two bonus rounds, and multiple feature buy options.
Respins
After all wins and cascades from a spin are complete, landing 3 or more wilds triggers a respin. During respins, wilds and scatters stick while all other symbols are cleared and replaced. Each respin doubles the multipliers on wilds, though wilds used in winning clusters are removed along with the win. If at least 3 wilds remain once cascades finish, another respin is awarded, allowing multiplier values to snowball.
Haunted Harvest
Triggering with 3 or 4 scatters, Haunted Harvest begins with a collect phase followed by a free spin. Scatter symbols transform into sticky wilds with multipliers of x2–x100. The phase starts with 3 spins, and each new wild resets the counter to 3. Only wilds land here—no regular symbols. When no new wilds land for 3 consecutive spins, the phase ends.
Collected wilds then remain for a single free spin. If the spin ends without a win, a mystery draw may grant an additional free spin, resetting the game back to the collect phase while retaining all existing wilds. Before the extra spin, multipliers on wilds double. The mystery draw has no cap, meaning free spins can theoretically chain indefinitely.
Phantom Treasure
Landing 5 scatters unlocks Phantom Treasure, which plays the same as Haunted Harvest but guarantees 2 free spins instead of 1, increasing the chance of a major haul.

-
BonusHunt FeatureSpins (3x bet): Each spin is 5x more likely to trigger free spins.
