How to play
- Shade some cells. Thick walls split the grid into rooms.
- A number says how many shaded cells its room has. Rooms without a number can have any count.
- Shaded cells never touch by an edge.
- All the white cells connect into one piece.
- No straight line of white cells crosses two walls, so a white line never spans three rooms.
- Tap a cell to shade it, again for a dot that marks it white, again to clear. Drag to paint.
Keyboard: arrows to move, space to cycle, s shade, d dot, 0 clear, Ctrl+Z undo, Ctrl+Shift+Z redo.
