A not too difficult fillomino puzzle to start 2025. I recommend you use the line tool to mark the little killer diagonals, and then colour the fillomino regions as you discover them (use colour=1 for size 1 regions, colour=2 for size 2 regions, ... colour=9 for size 9 regions).

Rules

Normal fillomino rules apply. That is, divide the grid into orthogonally connected regions such that no two regions of the same size touch each other orthogonally, and fill each cell in each region with the region's size.

Use only region sizes of 1 to 9 and the digit N cannot appear in row N or column N of the grid.

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.
