Bullshark Games has launched Gem Ghosts, a cluster slot that invites players into the depths of a haunted mine, where ghostly figures guard long-lost treasures. Built on a 6×6 grid, the release departs from traditional line-based mechanics and instead rewards clusters of five or more matching symbols. With a potential payout reaching 12,000 times the stake, the game positions itself as a high-volatility title shaped around cascading sequences and escalating multipliers.

The foundation of Gem Ghosts is its cluster mechanic, where symbols disappear once part of a winning combination, leaving room for new symbols to fall into place. This process can chain together multiple wins within a single round, sustaining the pace of play. The grid becomes particularly engaging when Wilds enter the equation, since they not only substitute for other symbols but also bring multipliers that can significantly elevate outcomes. These multipliers, ranging from 2x up to 100x, stack together whenever multiple Wilds contribute to the same cluster, creating opportunities for amplified results.

One of the defining aspects of the slot is the Respin Feature. Whenever three or more Wilds remain on the board after a sequence of wins and cascades, the grid resets with only the Wilds and Scatters locked in place. The rest of the spaces clear out and repopulate, while the multipliers on the Wilds double with each new respin. This mechanic introduces a level of continuity, as players can see their Wilds evolve with greater potential over repeated respins. If Wilds contribute to winning clusters, they are removed from the grid, forcing players to rely on the remaining ones to extend the feature. The loop ends only when fewer than three Wilds are left, or when a transition to the Free Spins round is triggered by landing three or more Scatters during respins.

The Free Spins feature introduces a two-stage sequence that departs from conventional formats. The initial phase, titled the Collect Phase, emphasizes gathering Wilds before a single, decisive spin occurs. During this stage, any Wilds appearing on the reels remain fixed, each carrying a multiplier value. Players begin with three spins, but the counter resets every time a new Wild lands, extending the phase for as long as fresh symbols continue to appear. Once the grid fails to produce a Wild for three consecutive spins, the phase concludes.

The final spin is where the collected Wilds become fully active. They remain in their fixed positions, with multipliers applied to any clusters they form part of. To add another layer, a random draw at the end of the sequence can award an additional Free Spin, which restarts the Collect Phase while preserving all previously gathered Wilds. If this happens, the multipliers on those existing Wilds double before the new round begins. Theoretically, this cycle can repeat without limit, offering an unpredictable rhythm to the bonus game.

The slot also includes an enhanced version of the feature, titled Phantom Treasure, which guarantees two Free Spins from the outset. This mode is triggered by landing five Scatter symbols and otherwise follows the same structure as the Haunted Harvest bonus. By offering a predetermined pair of Free Spins, it ensures extended engagement with the multiplier-driven Wild mechanics.

Gem Ghosts leans into the theme of a spectral treasure hunt, with its haunted mine backdrop reinforcing the sense of hidden riches lurking beneath the surface. Rather than relying solely on its visual theme, the game uses its mechanics, particularly the escalating multipliers and unpredictable respin cycles, to emphasize progression and momentum.

Bullshark Games has crafted Gem Ghosts as a slot that rewards sustained sequences rather than short bursts. The cluster system allows wins to build incrementally, while the doubling multipliers and recurring respins ensure tension remains throughout. Its Free Spins structure, built around collection and preservation rather than a fixed set of spins, sets it apart from more conventional bonus rounds. This creates a balance of familiarity with the cluster format while layering in mechanics that reshape the flow of play.
