Astrolabrium XL – Advanced Rotating Wooden Puzzle by Siebenstein-Spiele

Astrolabrium XL is a beautifully engineered rotating puzzle inspired by classical astronomical instruments. Crafted by Siebenstein-Spiele, this large-format wooden puzzle features layered construction, engraved celestial markings, and multiple rotating discs that interact in clever and unexpected ways.

The objective is deceptively simple: rotate the four movable discs so that no small or large black circles remain visible. Achieving this requires careful observation, sequencing, and alignment — as changes to one disc affect the others in subtle ways.
