Theme: Clue Symmetry and Logic
Author/Opus: This is the 136th puzzle from our contributing puzzlemaster Serkan Yürekli.
Rules: Standard Tight Fit Sudoku rules with digits from 1-9. Also, there are some dotted cages; the number clues given with these cages indicate the sum of all digits in the cage. Digits cannot repeat within a given cage.
Answer String: Enter the 6th row from left to right, followed by a comma, followed by the 6th column from top to bottom. (Note: for the tight fit cells, enter the top before the bottom as would be normal for the read order.)
