SlotRanker Score: 55 — Sanatorium Secrets by Pragmatic Play
https://slotranker.com/pragmatic-play/sanatorium-secrets#scoreSlot Summary
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.
This game is searched most in Brazil, Greece, and Argentina.
