Rules of Scrin: Shade cells to form rectangles. Rectangles don't share any cell side, but each rectangle shares corners with exactly two other rectangles. In this manner, rectangles enclose a single orthogonally connected unshaded area. All clues must be covered by rectangles, but no rectangle may cover multiple clues. Clue numbers indicate the area of its covering rectangle in cells.

Written to familiarise me with the genre, I don't really think it's a pleasant solve.
