Sanatorium Secrets: Survive the Haunted Hallways for a 10,000x Max Win

Sanatorium Secrets by Pragmatic Play feels like walking through the gates of an abandoned asylum at midnight. The haunted, creepy figure on the welcome sign of the six-by-four grid watches every spin. There are three types of wilds, a transforming symbol, and a no-purchase route to the super bonus round carrying up to 10,000x prizes.

My base game was versatile, and this time, that meant frequent wins between 0.5x and 7x my bet. Higher wins from that range depended on the wilds and on the Hook, a symbol on the outer reels that turns whole rows into wilds.

The standout hit came from two stacked wilds on the middle reels, each carrying an 8x multiplier that added together to push the spin to 40x my bet.

And that brings us to how the wilds are structured. There are three sizes of the same idea. The 1x4 stretches one reel high on the inner four, carrying 4x or 8x multipliers. The 2x4 covers a bigger block on the middle two reels, with heavier multipliers from 8x to 64x. The smallest 1x1 only shows up when the hook, transforming symbol, creates one.

As I hoped, the highlight came from free spins. There are two types, regular and super, and I worked with the first.

Three Scatters trigger it, but before the round starts, another way Pragmatic found to immerse us is the Puzzle feature. Puzzle pieces drop onto the reels in a pre-round, each adding a free spin to the bonus and pre-loading wilds. Mine settled at 15 spins, and the round closed at around 94x my bet.

Super Free Spins would have triggered with one Super Scatter on reel 6 alongside the three regular Scatters, and the difference is two guaranteed hooks carrying into the round, which probably means heavier wild action. There's a direct way to bonus rounds for 75x and 150x your bet.

My session had no weak links. The base game was a strong core, with everything else building on it. I recommend the adrenaline and shivers Pragmatic Play delivers with the Sanatorium Secrets slot game, so feel free to try the demo here on SlotsMate.
