#015: Aqre (Arbitrary Regions)
3 June 2022Encouraged by the interesting logic in the first Aqre (Arbitrary Regions), I set out to create a few more of these. I remember struggling quite a while until I found a symmetric clue placement where all regions could have integer clues.
Rules: Shade some cells so that all shaded cells form one orthogonally connected area. Regions with numbers must contain the indicated amount of shaded cells. There may not exist a run of more than three consecutive shaded or unshaded cells horizontally or vertically anywhere in the grid.
Variant: Arbitrary Regions — The clue regions are not restricted to the grid that is being shaded. Standard Aqre rules apply, except that the numbers indicate the total shaded area in each region (assuming that each cell has an area of 1).
