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.

WHITE KROPKI (NEGATIVE CONSTRAINT):
• Numbers in cells separated by a white dot have consecutive values.
Negative constraint: all possible white dots are given.

Solution code: Row 7, left to right
