More unique Sudoku puzzles that you’ve never seen before – for die hard fans of big Sudoku puzzles, here is another one – Double Sudoku Harakiri X!
There are 13 classic sub-puzzles, which of course don’t have their own (unique) solutions but all together constitute a puzzle with a single solution. This time, however, you must also pay attention to diagonals: ALL diagonals in the puzzle must contain all numbers from 1 to 9. The diagonals are marked in the puzzle so you wouldn’t forget them.
Thoughts and comments are most appreciated (as always)!
