Author/Opus: This is the 72nd puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Standard Tight Fit Sudoku rules. Remember, the smaller number goes above the larger number in all slashed cells. The range of this puzzle is 1-9.
Answer String: Enter the 2nd row from left to right, followed by a comma, followed by the 5th 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 = 1:20, Master = 2:00, Expert = 4:00
