Fortress of Shadows rises from Puzzle Master’s metal line like a miniature stronghold—its matte black cage forming the silhouette of a tower, while polished gold pieces create it's shining walls. This dramatic contrast hints at the layered, deliberate engineering that defines Christoph Lohe’s designs.
Inside the cage rest four interlocking gold components, each machined with crisp geometry and subtle tolerances. Careful exploration will reveal a precise sequence of shifts and slides that gradually loosen the fortress’s grip. The goal is to fully disassemble the internal assembly and then reconstruct it—an equally engaging challenge that rewards understanding over memorization.
Medium difficulty (8/10) — Accessible to intermediate puzzlers while still offering a meaningful, multi-step solve.
Architectural presence — The black frame resembles a fortified tower (complete with windows!), giving the puzzle a sculptural, display-worthy look.
Gold-on-black contrast — Highlights the internal mechanics as the structure begins to open.
Four-piece burr-style core — A compact but clever interlocking system that unfolds through every step.
Signature Christoph Lohe design — Clean geometry, tight tolerances, and a logical progression that feels both elegant and intentional.
