The World’s Most Challenging 3-D Puzzle


Said to have the power to stump a member of MENSA, the World’s Most Challenging 3-D Puzzle is not a mere toy. Created by an MIT mathematician, the puzzle was inspired by an 18th Century mathematical conundrum known as The Problem Of The 36 Officers (which eventually proved to be unsolvable). While the puzzle does have a solution, with one quadrillion (1015) possible moves, it requires patience, abstract thinking and lots of persistence to find it.
