Instructions

   

Draw a single continuous loop by connecting neighbouring dots along the dotted lines. The numbers indicate how many edges of a cell are used for the loop. The loop may not touch or cross itself, and it doesn't need to touch all of the dots. The cells that contain an even number (even if it is not given as a clue) cannot touch each other, even diagonally.
