Bullshark Games releases Doctor Dust slot via Hacksaw Gaming platform

Bullshark Games has released Doctor Dust, a 5×5 cascading cluster slot set in a post-apocalyptic wasteland whose protagonist is a plague doctor. The title launched on 9 October 2026 and is distributed through Hacksaw Gaming's OpenRGS platform.

Wins are formed by clusters of four or more matching symbols. Every winning symbol feeds a collection meter that unlocks Grid Boosters, four of which operate in the base game: Clone, which can reproduce a row across neighbouring rows; Switch, which transforms symbols within selected rows; Wilds, which add between two and five wild symbols; and Power Line, which clears a row and column before attaching multipliers to the affected cells. Multipliers on winning cells apply to the win and can combine when several land inside the same cluster.

Collecting 40 winning symbols during a single base-game spin triggers the Bonus Game, which begins with all four Boosters. The feature continues when at least eight winning symbols are collected on a spin, awarding another spin plus one to four Boosters depending on the number collected, making it an open-ended run rather than a fixed allocation of free spins.

Bullshark describes the game as high volatility with a maximum win potential of 12,000x the bet. Founder and CEO Andre Villandberg said the release builds on progression mechanics used in Age of Seth, with the Boosters intended to be understood individually before their interactions are discovered.
