Vintage Mike Reilly Cannonball Puzzle | Geometric Wooden Brain Teaser, NOS

Mike Reilly is a renowned name in the world of mechanical puzzles and wooden brain teasers, celebrated for his ability to transform complex mathematical concepts into tactile, aesthetic objects. The "Cannonball" series is one of his most iconic designs, requiring the user to stack various clusters of wooden spheres to form a perfect tetrahedron.

This 5x5x5 configuration offers a significant level of difficulty compared to smaller versions. Beyond its functional challenge, Reilly's work is frequently curated as "functional art" or "executive toys," fitting perfectly into contemporary office spaces or mid-century modern libraries. Finding an original Reilly design in its original packaging is becoming increasingly rare, making this a true collector's piece.
