Logic Masters Deutschland e.V.

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.
Put the given domino set in the shaded cells, each domino exactly once. When two dominos share the edge, the same numbers have to be on both dominos. Domino numbers are valid fences hints too.
