Jean-Claude Constantin
Prolific puzzle designer · Germany
Jean-Claude Constantin is a German puzzle designer and maker based in Nuremberg, widely regarded as one of the most prolific creators in the field. Despite his French-sounding name, he designs and manufactures from Germany, reportedly producing well over 70 new designs each year, so that dedicated collectors can amass a hundred or more of his puzzles.
Unusually for a designer, Constantin works across nearly every puzzle category—2D and 3D packing and assembly puzzles, sequential-movement puzzles, wire-and-string puzzles, interlocking puzzles, trick locks, and puzzle boxes. Many of his pieces use laser-cut plywood, often combining contrasting natural wood tones with metal components for a clean, graphic look.
His output spans approachable brain-teasers to fiendishly complex mechanisms, and his trick locks and boxes are especially praised for elegant designs hiding very difficult moves.
