Divide the grid
Split the board into rectangles. Each numbered clue sits in exactly one rectangle, and the number is that rectangle’s area in squares.
- Drag from one cell to another to draw a rectangle. It snaps to whole cells and shows its area as you drag.
- Release to keep a legal rectangle. Tap a drawn rectangle to remove it.
- Rectangles cannot overlap. A rectangle may contain only one clue, and its area must match that clue.
- Finish when every cell is covered once and every clue is satisfied.
- Hint explains one logical step. Undo and Restart are always there.
