This puzzle features a grid of squares, some containing numbers and others left blank. The numbers range from 0 to 3 and indicate how many lines should be drawn around that square. For example, a square with a "2" must have exactly two lines, while a "0" should have none. Squares without numbers can have any number of lines.
Your goal is to connect the lines in a way that forms a single, continuous closed loop.
To draw a line, click on the yellow guideline. Click again to remove it if needed.
