Rules: all black cells in a room must be connected horizontally or vertically (and together form a connected shape). A cell with a number indicates how many cells in the corresponding room must be blackened. In rooms without a number any amount of cells may be blackened (but at least one). Black cells may not touch each other across rooms horizontally or vertically. If blackened cells (and thus connected shapes) fall down, they must cover exactly the bottom half of the grid where the shapes must remain intact. So in the end, the solution contains connected black cells per room that, when dropped down exactly as shape, fit together and fill up the bottom half of the game grid.
