Move through detailed 3D rooms in a first-person point-and-click view, inspecting objects and searching for hidden clues, keepsakes, and treasures. Read writings left behind by the castle’s former occupants to piece together their stories.
Solve logic puzzles and operate mechanisms to open new rooms and uncover secret passages. Progress through connected areas, sometimes returning to earlier locations as new clues and puzzles come into view.

Some find the mystery and discoveries rewarding, while others feel that later puzzles become too obscure and that searching for tiny objects, collectibles, or clues can interrupt progress.
