Normal sudoku rules apply.

In the grid, construct a non-intersecting loop of orthogonally or diagonally connected cells which:

1) Contains two or three cells in every box;

2) Is symmetric about the negative diagonal, but contains no cells on that diagonal;

3) Never contains the value N in box N; and

4) If it contains a segment in box N, the values on that segment must differ by N.

Global constraints:

1) Digits may not repeat on the positive and the negative diagonal; and

2) Digits separated by a king's move in chess cannot be the same.

3) Digits separated by a V sum to 5.

4) Digits separated by an X sum to 10.

5) All V's and X's in the grid are given.
