FORTRESS FILLOMINO:
• Divide the grid into orthogonally connected regions and fill each cell with a digit showing the number of cells in the region to which it belongs;
• N.B. In this puzzle, all regions must be single-digit (max. 9) in size;
• Each region must be either strictly larger than all of its orthogonal neighbours or strictly smaller than all of its orthogonal neighbours.

PERIODIC SUMS:
• A clue outside the grid shows the sum of N and every Nth digit thereafter in the indicated row or column, where N is the digit in the first seen cell;
• For example, a row of 345678912 would show a clue of 18 (3+6+9) on the left and 26 (2+9+7+5+3) on the right.
