Masyu: Draw a closed path into the puzzle, that passes every field with a circle. In fields with a black circle the path has to bent in a 90° angle and has to continue in both directions one field straight. Through fields with a white circle the path has to go straight and has to bent 90° in the next field in at least one direction.
Slitherlink: Draw a single continuous loop by connecting neighboring 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.
