FORTRESS FILLOMINO:
• Divide the grid into orthogonally connected regions and fill each cell with a number (not necessarily single-digit) showing the number of cells in the region to which it belongs;
• Each region must be either strictly larger than all of its orthogonal neighbours or strictly smaller than all of its orthogonal neighbours.

MODULAR LINE:
• Every set of three adjacent values on the teal line must contain one of each residue class modulo 3;
• I.e. one value from [1, 4, 7, 10...], one from [2, 5, 8, 11...] and one from [3, 6, 9, 12...].
