How the Game Plays

Sanatorium Secrets is a dark, atmospheric slot from Pragmatic Play set within the crumbling halls of an abandoned medical facility. Played across a 6x4 grid with 4,096 ways to win, the game creates a sense of unease through its haunting visuals and eerie sound design. Symbols include standard royal icons alongside more thematic depictions of sanatorium staff, patients, and their terrifying undead versions. Winning combinations are formed by matching symbols on three or more adjacent reels, starting from the leftmost side. Unlike many high-variance horror titles, this game utilizes a medium volatility model, aiming for a more balanced distribution of wins.

Free Spins Explained

The main bonus round is triggered by landing three or more scatter symbols. Before the spins begin, the Puzzle Feature initiates a series of respins where players collect puzzle pieces to fill the reels. Successfully completing a puzzle transforms that entire reel into a persistent Wild for the duration of the free spins. If the round is triggered by a Super Scatter, the bonus is upgraded with enhanced mechanics. Players can also retrigger the feature by landing additional scatters or completing more puzzles during the round.

Hook Symbol & Puzzle Mechanics Explained

A standout element of Sanatorium Secrets is the Hook symbol, which appears on the outer reels. When this symbol lands, it acts as a collector, transforming character symbols into high-paying icons or Wilds. It can also activate multipliers that significantly increase win potential. The Puzzle Feature, which transitions the base game into the bonus, allows players to build up their grid with wild reels, providing a strategic layer to the standard spin cycle.
