The end of its reply
Looking at this puzzle, I'll solve it systematically using elimination and constraint propagation.
**Key deductions:**
1. Row 3: missing {6,7} → (3,5) must be 6 (column 5 constraint), so (3,2) = 7
2. Row 1: (1,8) = 3 (only option in col 8), then box 1 forces (1,1) = 4, giving (1,4) = 9, (1,6) = 1
3. Row 4: col 4 already has 8 at (2,4), forcing (4,4) = 6 and (4,3) = 8
4. Col 2: (6,2) = 3 forced by elimination (both (7,2) and (9,2) must take {5,6})
5. Col 7: (8,9) = 4 (only empty in box 9 with col 9 missing only 4), then (6,7) = 6 forced
6. Row 5: (5,5) = 4 (only option in col 5), then (5,7) = 3, (5,3) = 6, (5,1) = 9
7. Box 1: (2,3) = 2, so (2,1) = 6
8. Col 1: (9,1) = 8, (6,1) = 7, (8,1) = 2
9. Remaining cells fall into place through systematic elimination.
