Theme: Clue Symmetry and Logic
Author/Opus: This is the 105th puzzle from our contributing puzzlemaster Serkan Yürekli.
Rules: Fill the grid with digits from the indicated range (1 to n) so that no digit is repeated within a row or column. Number clues in the grid indicate the difference between the largest and smallest digits in the visible cells (i.e., going from the clue until hitting an edge or another triangled cell). If there is only one visible cell, the clue number indicates the digit itself.
Answer String: Enter the digits in the 4th row from left to right, followed by a comma, followed by the 10th column from top to bottom. Ignore the triangled cells.
Time Standards (highlight to view): Grandmaster = 4:00, Master = 5:45, Expert = 11:30
