Scrin
Divide the grid into rectangles so the circled rectangles form a single corner-touching loop.
Controls
Draw rectangles to cover every cell. Each rectangle may contain at most one circle, and a numbered circle must match the rectangle’s area; an empty circle leaves the area open. The rectangles containing circles must form one non-branching loop by touching only at corners, and two circled rectangles may not share an edge. Drag across cells to create rectangles; use Clear to reset and the answer button to reveal or hide the full partition.
