Sandwich sums: numbers outside the grid indicate the sum of all cells between 1 and 9 in that row or column, excluding 1 and 9 from the sum.
Fortress cells: Shaded cells are fortress cells and must be larger than all orthogonally adjacent cells.
All possible fortress cells are shown. That is, there is a negative constraint on fortresses and any unshaded cell must be orthogonally adjacent to at least one larger digit.
Try the puzzle on CTC.
