Sanatorium Secrets

The gates are rusted shut, the mist never lifts, and whatever happened inside those walls has never quite been explained. 

Sanatorium Secrets drops you into Pragmatic Play's darkest corner yet, a 6x4 horror slot built around psychological dread, wildly stacked multipliers, and a two-part bonus round that doesn't hold back. 

It's one of the more feature-rich slots in the Jackpot.bet library, and one of the few that earns its atmosphere rather than just wearing it.

How to Play Sanatorium Secrets

Sanatorium Secrets plays on a 6x4 grid with 4,096 ways to win. All wins pay from left to right on adjacent reels starting from the leftmost reel. 

The minimum bet is $0.20 and the maximum is $240 per spin. 

An Ante Bet option is available, selecting the 40x multiplier increases your chance of triggering Free Spins fourfold, while the standard 20x bet plays at normal frequency.

Theme and Graphics

The sanatorium sits in permanent twilight, surrounded by mist and crumbling stone. Restricted area signs line the gates. 

The soundtrack keeps the tension constant without being heavy-handed, crow calls, distant echoes, something that might be footsteps. 

The four character symbols tell a story without explaining it: a pale-skinned woman with something wrong about her eyes, a blonde figure that seems out of place, an older man who clearly knows more than he's saying, and a doctor in green whose expression gives nothing away.

It's the kind of horror slot theme that commits fully rather than gesturing at spookiness.

Symbols and Paytable

All values based on a $1 bet.

Sanatorium Secrets Key Features

Six reels, stacked wilds, and a two-part bonus round that builds before it even begins, here's what drives the action in Sanatorium Secrets.

1x4 Wild with Multiplier

Appears on reels 2, 3, 4, and 5. Substitutes for all symbols except Scatter and Super Scatter. Carries a random multiplier of 4x or 8x that applies to all winning combinations passing through it. Multiple multipliers on the same win add together.

2x4 Wild with Multiplier

Appears only on reels 3 and 4, covering two full columns simultaneously. Carries a random multiplier of 8x, 16x, 32x, or 64x, the highest available in the base game. When multiple multipliers land on the same win, they add rather than multiply together.

Hook Symbol

Appears only on reels 1 and 6. When it lands, it grabs all high-paying symbols on the same row and transforms itself into a matching high-paying symbol or cluster. 

Those high-paying symbols convert into 1x1 Wilds. If the Hook passes over an existing Wild, it doubles that Wild's current multiplier.

Free Spins and Puzzle Feature

Land 3 or more free spins Scatter symbols on reels 2–5 to trigger the bonus. The round starts with 6 spins plus 2 for each additional Scatter beyond the third. 

Before the feature begins, the Puzzle Feature plays out, high-paying symbols can transform into Wilds when their associated reel is completed vertically with puzzle pieces. Each puzzle piece that lands awards an additional respin and an extra free spin for the main round.

Super Free Spins

Landing 3 Scatters alongside the Super Scatter on reel 6 upgrades the feature. Two Hook symbols are guaranteed during the Puzzle Feature and remain active throughout the bonus round.

Multiplier floors are raised, increasing the minimum value the 1x4 Wilds can carry into free spins.

Ante Bet

Selecting the Ante Bet increases your chance of triggering free spins fourfold at a 40x bet multiplier. Standard play runs at 20x with normal trigger frequency.
