Normal fillomino rules apply (ie divide the grid along grid lines into non-overlapping regions of orthogonally-connected cells such that no two regions of the same size touch each other orthogonally; and fill each cell in each region with that region's size ie the number of cells in its region). Use only the digits 1 to 9 and the digit N cannot appear in row N or column N. Digits on the marked diagonals cannot repeat and must sum to the total (if given). The grid is covered by fog. Correctly placing digits may clear fog somewhere in the grid.
