Stostone Fillomino
I couldn't decide whether to make a stostone or a fillomino, so why not both? Hopefully it is fun to solve :)
Rules:
- Divide the cells in the grid into regions so that no two regions of the same size share an edge.
- Each cell contains a number equal to the size of its region.
- Shade at least one cell in each region such that all shaded cells in a region form an orthogonally connected group.
- If two shaded cells are orthogonally connected, they must be in the same region.
- If all of the shaded groups were to fall straight down without changing shape, they must completely fill the bottom half of the grid.
- The number in a cell with an arrow gives the number of shaded cells in the direction of the arrow, not including the arrow cell.

Terrific puzzle, thanks! I'm glad Phistomefel recommended it (from their puzzle "Stostone Cold".)
Here is a Sudokupad version. For the solution check to work, enter only the units digit in each cell. https://sudokupad.app/6es6owotyl

Very fun puzzle! I would love more like this. For anyone thick-headed like me, the units digit means the digit in the ones place (at least in base-10). I didn't know that until today!
