The end of its reply
Looking at this Sudoku, I'll work through it systematically using constraint analysis.
**Key deductions:**
- Column 4: (1,4) and (3,4) form a hidden pair {1,5} since only they can take 1 or 5
- (8,1)=3 (box 7 constraint with column 1)
- (4,1)=6, (3,1)=8 (column 1: only options)
- (5,4)=4 (only cell in column 4 that can take 4)
- (7,5)=1 (only cell in column 5 that can take 1)
- (7,6)=5 (row 7 pair)
- (4,5)=5 (only cell in column 5 that can take 5)
- (5,6)=1 (only cell in box 5 that can take 1)
- (9,6)=3, (9,4)=9, (8,6)=8 (box 8/column 6 analysis)
- (4,7)=1 (only cell in box 6 that can take 1)
- (3,6)=7 (only remaining value in column 6)
- (3,9)=2 (only cell in column 9 that can take 2 in box 3)
- (3,8)=4 (only cell in row 3/box 3 that can take 4)
- Then cascading singles complete the puzzle
