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.

XV PAIRS:
• Cells separated by an X sum to 10
• Cells separated by a V sum to 5
• Not all possible Xs and Vs are necessarily given
