Theme: Clue Symmetry and Logic
Author/Opus: This is the 132nd puzzle from our contributing puzzlemaster Serkan Yürekli.
Rules: Standard Tight Fit Sudoku rules with digits from 1-9. Also, digits cannot repeat in any cells separated by a chess knight’s move (both digits in any “tight fit” cell are considered when checking for presence in a cell a knight’s move away).
Answer String: Enter the 2nd row from left to right, followed by a comma, followed by the 3rd row from left to right. (Note: for the tight fit cells, enter the top before the bottom as would be normal for the read order.)
Time Standards (highlight to view): Grandmaster = 2:15, Master = 3:00, Expert = 6:00
