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.
QUADRUPLES:
• Numbers in a Quadruple circle must be placed at least once in the four cells touching that circle (note that in this puzzle, there are only single-digit numbers in circles).
• If a number appears multiple times in a circle, that number must appear at least that many times in the four cells touching the circle.
Solution code: Row 5, left to right
