Play Rectangles

Hints cost 10 coins

Rectangles asks you to tile a grid with non-overlapping rectangular regions. Every numbered clue belongs to exactly one rectangle, and that number is the rectangle's area in unit squares. Drag from cell to cell to outline a candidate rectangle; release to keep it if it is legal, or tap an existing rectangle to remove it. The puzzle is complete when every cell is covered once and every clue is satisfied.
