Developer Sanatorium Secrets is a casino slot from Pragmatic Play built around wild multipliers, hook symbols and a two-part bonus structure. In the base game and bonus rounds, 1x4 expanding wilds can appear on reels 2 to 5 with multipliers up to 8x, while 2x4 fiery wilds can cover reels 3 and 4 with values reaching 64x.
Hook symbols on reels 1 and 6 convert all high-paying symbols on the same row into 1x1 wild symbols, then change into the matching symbol. Three scatters on reels 2 to 5 trigger six free spins, with two extra spins for each additional scatter. A super scatter alongside three scatters unlocks Super Free Spins.
A puzzle respin feature plays before the free spins begin, setting the minimum wild multiplier for the bonus round and potentially activating hook symbols and 1x1 wilds. Each puzzle piece can award more respins and free spins, while completing the puzzle grants the maximum win. Use the demo version to play for free and practice before playing for real money.
