The end of its reply
Looking at this puzzle, I'll work through it systematically using constraint propagation and elimination.
**Key deductions:**
1. R1C3=7 (only option in that cell)
2. Box3 analysis forces R2C7,R2C9={1,3}, and R3C7=8
3. Column 9 analysis: R7C9=5 (only cell that can hold 5)
4. R7C8=8, then R7C7=7, R7C3=2, R7C4=3
5. Box7 forces R3C1=2, then cascading through column 1
6. Box5: R6C6=5, then R2C6=2, R3C6=4
7. Row 4: R4C5=2, R4C4=1
8. Column completions force the remaining cells
