Each row, column and region, and each of the two main diagonals, must contain the digits from 1 to 9.
"Target in the fog"
With some French friends, we are working on the project of writing a book of sudoku.
Some grids created for this occasion will not have their place in the book, including this diagonal sudoku: a bit too hard...
Lösungscode: Both main diagonals, first from top left to bottom right and then from top right to bottom left.
