Theme: Clue Symmetry and Logic
Author/Opus: This is the 109th puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Standard Tapa-Like Loop Rules. (Form 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:
Also, there are two windows in the upper left (blue) and lower right (red) of the grid. If a cell is used by the loop in one window, then the cell in the same position in the other window is not used by the loop.
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”.
