Half full or half empty?
(Published on 13. January 2021, 21:26 by Terttu5)
I saw this puzzle type in the DASH 11 puzzles. Puzzle is number 3, called Kidney. My version of the puzzle includes only the first half of it, not the crossword part.
Shade cells in the grid below according to these rules:
- Each sector - a bold-outlined region - must contain exactly one stone.
- A stone is a mass of contiguous shaded cells (sharing edges).
- Stones from different sectors may not share sides, but can touch at corners.
- If a region contains a number, exactly that many cells must be shaded.
- Shade half the cells in each column.
- If dropped, stones will stack at the bottom of the grid, clearing the top half. Each stone remains intact, keeping its shape, but will not rotate. It must be able to nest perfectly on any stones below it, so that the stones completely fill the lower half of the grid.
Solution code: Number of shaded cells in rows, top to bottom.

@SudokuExplorer - There is a 2x1 block in the top right that you have no stone in.
