#117: Aqre (Twilight)

This was my first entry to Logic Showcase #49 on Puzzlers Club, “Twilight Sparkle”. The prompt was to set variant puzzles where shaded (or otherwise covered) clues behave differently from unshaded clues. The idea of Twilight Aqre had been on my to-do list since the Twilight Cave I made for last year’s Black-Out Friday.

I considered trying to stick with clues in the top-left corner, but ultimately decided that for a “logic showcase” it makes more sense to explore what deductions are possible by placing the clues freely.

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: Twilight — Shaded clues indicate the number of unshaded cells in their region instead.
