Description: The challenge is to construct a square block of numbered cubes, arranged in such a way that every possible row, column and side around the block contains each of the numbers 1 - 9. Meanwhile inside the block, every 3x3 section, sliced vertically or horizontally, also consists of the digits 1-9. So pit your wits against the invisible force of 27 magnetic cubes in this ingenious puzzle.
