Somewhere inside this pyramid framework, a cube is waiting to be found. The Egyptian Triglyph is a two-part challenge disguised as a single object: first extract the seven-piece cube concealed within the pyramid, then reassemble it back inside the same framework — a task that turns out to be considerably harder than taking it apart.
Ancient Geometry, Modern Design
Inspired by the precision and proportion of pyramid architecture, the Triglyph pairs an elegant form with a genuinely demanding solve. It was designed by Oskar van Deventer, a puzzle inventor known for mechanisms that look simple and behave otherwise — which is exactly the appeal here. What sits on a shelf as a clean geometric object turns, in your hands, into an exercise in spatial reasoning and careful sequencing.
