George and Roxanne Miller own the world’s biggest collection of mechanical puzzles. The couple has accumulated over 80,000 puzzles, including a variety of Rubik’s Cubes and wooden burr puzzles. Some of their favorite pieces are the polyhedral creations by Massachusetts puzzle maker Stewart Coffin and brass, bronze, and gold puzzle sculptures by Spanish artist Miguel Berrocal. The Millers recently bought a 15th-century castle in Panicale, Italy, and transported their collection there in five 40-foot shipping containers. Before departing for Italy, they went on a two-month road trip, accumulating even more puzzles from various friends and contacts. In Garden Grove, California, they acquired 58 boxes of puzzles from Marti Reis, and in Austin, Texas, puzzle maker Lee Krasnow hand-delivered his famed Clutch Box to them.
