Numbered Rooms: Some rooms contain a single number. This number indicates the exact quantity of cells within that room that must be painted black.
Black Cell Restrictions:
Black cells cannot be placed adjacent to each other horizontally or vertically.
All white cells must be connected.
A line of connected white cells cannot connect more than two rooms.
The goal of Heyawake is to fill in the grid with black cells according to the numbers provided, ensuring that black cells are not connected, white cells form a continuous path, and rooms are properly separated.
