Does Sudoku Work Diagonally?

Does sudoku go diagonal? The short answer is: no. In regular sudoku there are no diagonal rules that state the two 9 cell diagonals must contain all the numbers 1 through 9. There is however a variant of sudoku that does add this rule as an additional constraint: diagonal sudoku (also known as X sudoku).
