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.

DOUBLE ARROWS:
• The sum of the numbers along a grey line must be the same as the sum of the numbers in the two connected circles

Solution code: Column 6

This was lovely but damo, be careful - when you stare into the abyss, sometimes the abyss recruits you into setting a Full Rank puzzle.
