Have another Remembered Length! I don’t think this genre is going to get old any time soon. Discussion of this particular tilted square theme came up on Discord, and while I’ve used this exact layout before, I felt inspired to revisit it with a different genre.
Rules: Draw an oriented, non-intersecting loop through the centres of all cells. When crossing a boundary, the number clue in the previous region (if any) indicates how many cells the loop visits before crossing another boundary.
