Dare to cross the threshold into a decaying Victorian gothic mansion, forever shrouded in perpetual twilight and a chilling, ghostly fog. Mysterious plunges players into an eerie realm where gas lamps flicker ominously, casting long, dancing shadows upon the dusty portraits of its spectral inhabitants – the Lord, Lady, Baron, and Baroness. The air is thick with mystery and the faint whispers of untold secrets, as gargoyles gaze down from their perches, guarding the chilling truth within. A haunting soundtrack and intricate visual details create an atmosphere of spine-tingling suspense, promising both terror and tremendous treasure for those brave enough to explore its depths. With each turn of the reels, the spectral figures stir, unleashing their enigmatic powers through four random modifiers. The Lord commands random wilds to appear, the Lady unveils mystery symbols that transform into identical icons, the Baron grants multiplier wilds to boost payouts, and the Baroness unleashes expanding wilds that fill entire reels. The true terror and triumph unfurl when three or more antique Clock Scatters chime, transporting players into the mansion's deepest chambers for a choice of two formidable Free Spins modes. Endure the 'Free Spins with Locking Multiplier Wilds,' where ghostly multipliers cling to the reels, or brave the 'Free Spins with Resurrecting Roaming Wilds,' as apparitions float across the grid, leaving a trail of spectral wins. This highly volatile quest for riches can culminate in an astounding maximum win of 9,648 times the stake, as the mansion's dark secrets command unparalleled fortune.
