Building Regions in Fog of War: Border Patrol 2
(Published on 7. April 2024, 12:24 by Jeet Sampat)
Rules:
Fog of war - The grid is covered in fog which hides some cells. Place correct digits to reveal surrounding cells.
Chaos construction - Construct eight orthogonally connected 10-cell regions and one 1-cell region. Fill the entire grid with digits 0-9 so that no digit repeats in any row, column, or region.
Border patrol - A corner/edge shared by two cells is called 'occupied' if it lies on a region border. A digit in a clued cell counts the number of occupied corners/edges (not including those on the boundary of the grid) in all indicated directions combined together.
Internal little killer clues - A digit in a cell with diagonal clue(s) gives the sum of digits along all indicated diagonals combined together.

Cool and interesting, though I had to guess a bit to resolve some of the final digits

Surprisingly smooth with lots of really cool interactions. The constraints worked well together.
