This is a Melon puzzle. (26 – Domino Slitherlink)
or solve online (using our beta test of Penpa-Edit tools; ue tab to alternate between edgex mode where left click+drag draws lines and right click marks X’s and shading and number entry modes.)
Theme: Symmetry and Logic
Rules: Variation of standard Slitherlink rules. First, place the ten dominoes given below the grid into the gray areas, without overlapping, to form a valid Slitherlink puzzle; dominoes can be rotated. Solve the resulting Slitherlink following normal rules. (Note: The set of digits placed into the grid from the dominoes is unique, but the assignment of dominoes need not be unique.)
Answer String: Enter the length in cells of each of the internal loop segments from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma.
Time Standards (highlight to view): Grandmaster = 7:30, Master = 17:30, Expert = 35:00

Last time I saw this variation was during the slither link puzzle pack, and remembering some of the tactics used there helped a lot.
Palmer’s slitherlink variations are always a treat <3
I can assure everyone that the last clue in the 3rd row is necessary. I solved almost the entire puzzle until I was left with a few choices for the top right. Incredulous, I checked the blog to see if I had missed a clue when I copied it, and lo and behold!
This variation was a joy!
