Normal Sudoku rules apply.
You must build the outer wall of your fortress: a one-cell wide loop of orthogonally-connected cells that does not touch itself, even diagonally. Each digit on your wall must be greater than all orthogonally adjacent digits off the wall.
Digits in circles are NOT on the wall and indicate how many of the 8 orthogonally and diagonally adjacent cells ARE on the wall. In the set of circled digits, no digit may repeat.
Shaded squares contain even digits (with no other restrictions).
Solution code: Column 7
