Building Regions in Fog of War: Border Patrol 1
(Published on 23. March 2024, 17:59 by Jeet Sampat)
Rules:
Fog of war - The grid is covered in fog which hides some cells. Place correct digits to reveal surrounding cells.
Region building - Construct eight orthogonally connected 10-cell regions. 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 a region border passes through it. A digit in a clued cell counts the number of occupied corners/edges (not including those on the boundary of the grid) in each indicated direction separately.
Region sum lines - Region borders divide a blue line into segments with equal sum. Lines are allowed to lie in only one region and give no information.

Really nice puzzle - quite approachable too, I thought. I made some similar chaos construction puzzles in the past, with some similar rules.
Just one clarification - I wasn't sure that the single cell region could contain a digit - might be worth clarifying that it can.
