Double Diagonal Sudoku is a very interesting Diagonal Sudoku variation. In Diagonal Sudoku we have two main diagonals of size 9 on which no number can repeat. It means that all numbers from 1 to 9 are used exactly once on these diagonal. However, in Double Diagonal Sudoku, there are four diagonals of size 8 on which numbers cannot repeat. It means that each of the four diagonals contains only 8 numbers and one number goes missing in each diagonal. It is very interesting to find that which number is missing in these diagonals and sometimes finding the missing number from the diagonal itself helps to solve this puzzle very fast. This is my first Double Diagonal Sudoku on this blog and I am looking forward to creating more Sudoku puzzles of this Sudoku type soon.
