Re: Calcudoku with diagonals

Here's a solution, one of 152 found by my solver:
5 4 3 1 6 7 2
2 5 1 4 7 6 3
6 1 5 7 3 2 4
4 2 7 6 1 3 5
1 7 4 3 2 5 6
7 3 6 2 5 4 1
3 6 2 5 4 1 7
Still something not quite right though, because it can't find a solution with different numbers on both diagonals
152!!! I did not imagine so many (without the restriction for the diagonals), this demonstrates anyway the difficulty of creating Calcudokus with a unique solution, specially if you do not include individual cells, like in this case, because always the permutations work against you (this was discussed a little bit in the past, in this Forum, IIRC).
Sure the correct solution (or solutions) is among those 152, though very tedious to find it "manually", that is, without an automatic filter, otherwise something would be too wrong in your solver
(at least, some of us, seem to have one, I have verified mine, though we cann't show them until kozibrada does).
