Sanatorium Secrets Demo & Slot Review
Sanatorium Secrets places a misty sanatorium horror theme on a 6×4 grid with 4,096 ways. Expanding Wilds carry multipliers, Hook symbols rewrite premium characters on a row, and a Puzzle respin stage shapes Free Spins or Super Free Spins before they begin.
Demo availability may vary by location. You must meet the legal age in your jurisdiction; the free-play button does not record acceptance.
Sanatorium Secrets
Sanatorium Secrets is a medium-volatility horror video slot from Pragmatic Play, released on 1 June 2026.

Sanatorium Secrets review overview
6×4 ways and expanding Wilds
Wins form across six reels and four rows as 4,096 ways, adjacent from left to right. Most symbols need three matching reels; the top character can also pay for two. The attached rules paytable at the $2 stake shown uses stake-linked preview dollars, not a reconstructed absolute table.
A 1×4 Wild can fill reels 2–5 with a 4× or 8× multiplier. A fiery 2×4 Wild covers reels 3–4 with 8×, 16×, 32× or 64×. Multipliers on the same winning way are added, not multiplied together.
Hook transforms
A Hook on reel 1 or 6 converts high-paying symbols on its row into 1×1 Wilds, then becomes that premium symbol. If it crosses a multiplier Wild, that Wild’s multiplier doubles. Hooks are available in base play as well as in Free Spins.
Who Sanatorium Secrets suits
Sanatorium Secrets suits readers who want interacting Wilds, Hooks and a two-stage bonus rather than a simple scatter-to-spins jump. It is less suited to anyone who prefers flat paylines, a light theme or low fixed feature costs.
Best for
- Players comparing Hook row transforms with ordinary expanding Wilds
- Readers checking Puzzle prep before Free Spins or Super Free Spins
- Anyone verifying the listed 94.49%–96.47% RTP builds
Not ideal for
- Players who want uncomplicated paylines without Hooks
- Anyone treating 10,000× as a short-session target
- Readers skipping Ante Bet and Buy Feature stake multiples

How Sanatorium Secrets rules and features work
Puzzle, then Free Spins
Three or more Scatters on reels 2–5 open Free Spins from a base of six, plus two for each extra Scatter. A Super Scatter on reel 6 with three Scatters opens Super Free Spins. Before either mode, a Puzzle stage starts with three respins; each new piece adds one respin and one Free Spin. Completed columns can turn their premium symbol Wild for the bonus, collected Hooks can recur, and a +1× modifier can raise the 1×4 Wild minimum. Filling the entire Puzzle awards the 10,000× maximum and ends the feature.
Ante Bet and Buy Feature
Ante Bet raises the Free Spins trigger chance and doubles the per-spin stake. At the $2 stake shown, Buy Free Spins previews $150 and Buy Super Free Spins previews $300, equal to 75× and 150× the base bet. Those dollars are stake-linked preview figures. Super Free Spins guarantee two Hooks in the Puzzle and throughout the following Free Spins.
How to play Sanatorium Secrets responsibly
Ante Bet doubles each spin cost, and Buy Feature entries scale with the stake. Set a money limit and a time limit before you start, include any purchase in that budget, and stop when either limit is reached.
-
Check the RTP build first
Studio RTP lists 96.47%; other published builds show 95.47% and 94.49%. Confirm the information panel of the version you open.
-
Price Ante Bet and buys against your stake
Ante Bet doubles the spin cost. 75× and 150× buys are entry prices at the selected base bet, not prizes.
-
Treat 10,000× as a ceiling
A full Puzzle award or feature stop at 10,000× is a published maximum, not evidence that the next buy is due.
Symbols and Paytable
Expanding Wilds carry listed multipliers. Hooks convert premium characters and can double a Wild multiplier. Scatter and Super Scatter open the two-stage bonus. Card ranks fill the lower pays on the 6×4 ways grid.
1×4 Wild
Appears on reels 2–5 in base and bonus play. Substitutes for all except Scatter and Super Scatter. Can randomly carry a 4× or 8× multiplier. Multipliers add when more than one participates in the same winning way.
2×4 Wild
Spans reels 3 and 4. Substitutes for all except Scatter and Super Scatter. Can randomly carry 8×, 16×, 32× or 64×. Multipliers on the same winning way are added, not multiplied together.
Hook
Lands on reels 1 or 6. Converts high-paying symbols on the same row into 1×1 Wilds, then becomes that premium symbol. Crossing a multiplier Wild doubles that Wild’s multiplier.
1×1 Wild
Appears on reels 2–5 only when a Hook converts a high-paying symbol. Substitutes for all except Scatter and Super Scatter.
Scatter
Can appear on reels 2–5. Three or more Scatters trigger Free Spins. Each extra Scatter beyond the third adds two starting Free Spins to the base count of six.
Super Scatter
Appears only on reel 6. Together with three Scatters it triggers Super Free Spins, which guarantee two Hooks in the Puzzle and throughout the following Free Spins.
Premium characters
Four character portraits form the higher-paying set and are the symbols Hooks convert. Dollar awards on the attached rules paytable at the $2 bet shown are stake-linked preview figures.
Card ranks 9–A
Lower-paying set on the 6×4 ways grid. Most symbols need three or more adjacent reels from the left; exact dollar cells on the rules frame are preview figures at the $2 stake shown.
Sanatorium Secrets RTP, volatility and maximum win

RTP is a long-run value, not a short-session forecast.

How to interpret the numbers
Key point 1
A Hook without a paying way is not a finished award; read whether the converted symbols actually form a left-to-right way.
Key point 2
Read Buy Free Spins and Buy Super Free Spins dollar meters as stake-linked preview prices at the bet shown, not as fixed cash awards.
Key point 3
A 94.49% build is a different configuration from 96.47%. Check the information screen for the version you opened.

Sanatorium Secrets compared with other games
Other Pragmatic Play horror slots also use expanding Wilds and Buy Feature menus, but shared branding does not copy Hook row transforms or the Puzzle prep stage. Compare how multipliers are added, what the Super Free Spins guarantee changes, and which RTP build the lobby loads.
| Game | Return / max win | Volatility | Bonus fit | Watch out for |
|---|---|---|---|---|
| Sanatorium Secrets | 94.49%–96.47% / 10,000× | Medium | Three or more Scatters open Free Spins after a Puzzle stage; a Super Scatter upgrades that path to Super Free Spins with two guaranteed Hooks. | Shared horror art does not make another title’s Wild multipliers, buy prices or RTP prints apply here. |
| Hell Butcher | 94.48%–96.55% / 20,000× | Medium | No Miss and Madness variants change hook certainty and which trail values stay available. | A familiar Pragmatic Play Buy Feature menu does not make another title’s multiplier rules apply to Hell Butcher. |
| Coven Rising | 94.49%–96.42% / 5,000× | Medium | Three to six Scatters open 12 to 24 Free Spins; rune upgrades and a carried Coin can persist for the feature. | Shared dark fantasy art does not make another studio’s cluster or buy menu apply here. |
