    Three dimensional Sudoku

    This is a challenging puzzle type. If you love Sudoku, you might like this as it is not restricted to a 3 X 3 box. The margins could be larger for the possibilities work needed on the special shapes. The numbers still are used only once in the vertical and hrizontal directions but they must result in the number in the particular shaped block, which could be L-shaped or retangular. To make it more challenging, the author presents the mathematical process which you must use to arrive at that number.
    Only try if you love math and challenges.
