101 Giant 3D Sudoku, Paperback/Clarity Media

Description Welcome to this fantastic collection of 101 GIANT 3D Sudoku Puzzles To solve these puzzles, you will need to place each number from 1-9 exactly once into every region in the grid. There are 27 faces of a cube in the grid, represented as 3x3 boxes with bold-lines. Each of these regions must contain 1-9 once. In addition, there are 54 rows/columns that must also contain 1-9 once. These begin at each of the squares around the edge of the grid, and run for nine squares in a straight line that may travel over multiple faces of the giant sudoku cube. Thick lines show you where these regions end in the grid, in instances where they do not simply end at the edge of the grid. To help you visualise the 3D nature of the grid, we have coloured each of the three types of cube face in a different shade of grey. All puzzles in the book can be solved through the use of logical rules alone, you'll never need to guess. Puzzles are printed on high quality paper in a large 8.5 x 11 inch book.
