A square grid is divided into regions. The goal is to blacken some cells of the grid (stones) according to the following rules:
The areas enclosed with bold lines are called Rooms. The number in a room shows the number of continuous black cells in that room. Rooms with no number may have any number of black cells (at least one).
When all stones are "dropped" straight down (as in Tetris) the stones must fill the bottom half grid without empty cells.
