About this Slot
Sanatorium Secrets is a horror and history-themed slot from Pragmatic Play with an RTP of 96.47%, medium volatility and a maximum win of 10,000x. The game plays across 6 reels, 4 rows and 4096 paylines.
A Hook symbol grabs high-paying symbols on its row, transforms into them and converts them into 1x1 wilds. The Hook also doubles wild multipliers whenever it passes over them during a spin.
A 1x4 Wild symbol lands on reels 2 to 5, carrying a multiplier of x4 or x8. This multiplier applies to all winning combinations that run through it. When multiple wild multipliers are present on the same winning line, their values add together.
A 2x4 Wild symbol lands on reels 3 and 4, with multipliers ranging from x8 to x64. This larger wild functions identically to the 1x4 variant but offers higher multiplier potential.
The Puzzle is a hold-and-win feature that plays before free spins are triggered. Puzzle pieces lock in place and reset the spin count, while also awarding one additional free spin. When a puzzle reel is completely filled, the highest-paying symbol on that reel transforms into a wild.
Three scatter symbols trigger the free spins round, which begins with 6 free spins. Three scatters alongside a super scatter instead trigger the Super Free Spins round. Landing an extra triggering scatter during the bonus awards 2 additional free spins. Hooks and transformed wilds can appear during the bonus round, and outer reels may boost the minimum multiplier values available.
The Ante Bet option costs 2x your bet. Free Spins can be purchased for 75x your bet. Super Free Spins can be purchased for 150x your bet.
