From the rulebook
Heyawake divides the grid into bold-outlined rooms. Some rooms show a number, the exact count of black cells that belong inside. Shade cells black to satisfy every number.
Black cells may never share an edge, every white cell must stay connected, and a straight white line cannot run through three or more rooms. Tap a cell to cycle white, black, gray, then press Check when you think the board is solved.
