36 Cube

The 36 Cube is a puzzle that requires the arrangement of "towers" in a 6x6 square block so that each color appears only once in each row and column, all the same height. The completed puzzle will then be a cube. Jerry Slocum, a puzzle historian and one of the world's top puzzle collectors, finds 36 Cube one of the most engaging puzzles in his extensive collection. "My first impression was that it was quite a beautiful puzzle. Its three-dimensional character and colors are very striking. Out of the 30,000 puzzles I own, it's quite distinctive and unique." Dr. Niederman came up with the idea while writing a book on whole numbers, after unearthing a mathematical supposition from the 18th century. "It struck me as the basis for a potentially great 3-D puzzle, and what eventually became 36 Cube."
