Theme: Clue Symmetry and Logic
Author/Opus: This is the 153rd puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: In this variation of Tapa, the wall is in the form of a single non-intersecting loop. Clues inside the grid represent the number of neighboring cells visited by the loop; if there is more than one number in a cell, each number should be represented with a separate loop segment. There is no 2×2 rule of Tapa in this puzzle. This example image should help:
Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. Separate each row’s entry with a comma. For the example, this would be “11,12”.
Time Standards (highlight to view): Grandmaster = 2:30, Master = 5:00, Expert = 10:00
