Slot Summary

The space between a Horror setting and a mechanically meaningful pre-bonus stage is where Sanatorium Secrets operates. Pragmatic Play sends the feature through puzzle Respins before Free Spins, using collected pieces to set the minimum Wild Multiplier and unlock extra activity. In the base game, expanding Multiplier Wilds and Hook symbols alter rows, so the Mystery theme has a rules-level payoff rather than existing only as decoration.
MechanicsPuzzle Respins strengthen later Multiplier Wilds and Hook effects

How It Plays

Expanding Wilds can cover multiple positions and carry Multipliers, while Hooks on the outside alter high-paying symbols across a row. Both changes can affect ordinary wins.

The bonus does not move directly from its trigger into Free Spins. A puzzle Respin stage first collects pieces and determines which modifiers enter the following round.

Theme & Atmosphere

Horror supplies the institutional setting and threatening tone, while Mystery is expressed through a puzzle that reveals the strength of the coming bonus conditions.

The two themes remain connected to play: concealed puzzle pieces determine later values, and Hooks turn the setting's menace into a visible row-changing action.
