Sanatorium Secrets Brings Horror To The Reels
Sanatorium Secrets takes you into a dark gothic house wrapped in mist, backed by a tense piano-style soundtrack that builds the atmosphere nicely. The reels feature royal symbols from 9 to A, alongside four higher-paying character symbols, with the dark-haired lady paying the most at 10x your total bet for six in combination.
The game uses 6 reels and 4 rows, with wins landing from left to right. You need 3 or more matching symbols from reel one, though the top-paying symbol can award wins from just 2 matching symbols.
Hooks, Wilds And Puzzle Free Spins
The biggest draw here is the way Sanatorium Secrets handles its special symbols. The 1x4 Wilds can carry 4x or 8x multipliers, while the larger 2x4 Wilds can land with multipliers of up to 64x. When multiple Wilds are involved in a win, those values combine.
The Hook symbol adds the twist, appearing on reels 1 and 6 to grab high-value symbols across the same row, transforming them into Wilds. If the Hook passes over an existing Wild, it doubles that Wild’s multiplier, which gives the feature some serious potential.
Free Spins are triggered by landing 3 or more Scatters, while a Super Scatter can unlock the Super version. Before the bonus begins, the Puzzle feature plays out, giving players the chance to add extra free spins, place Hook symbols and transform high-value symbols into Wilds.
If you like layered bonus mechanics, you should find plenty to explore, especially with the max win sitting at 10,000 x your total bet.
