Sorry, this item is currently out of stock.

The idea for this puzzle comes from Jerry Slocum and Jack Botermans "New Book of Puzzles," and dates from the 1930's. The object is to get all 4 sides to add up to 555, the height of the Washington Monument! Each of the cubes will rotate on the internal post. A great challenge for the math inclined as it is VERY difficult. It might make a good class project from middle school to high school. Puzzle fan Ken Irvine has done an interesting analysis of this puzzle: turns out there are over 262,000 possible permutations of the disks. There are only 9 possible solutions.
