The end of its reply
Looking at this puzzle, I worked through it systematically using constraint propagation and case analysis. **Key steps:** 1. Column 3 was missing only 5 and 7; box constraints forced (5,3)=7, (9,3)=5 2. Box 8 analysis forced (8,5)=5, (8,4)=4 3. Row 5 and box 4 constraints forced (5,2)=1, (6,2)=2 4. Box 5 analysis determined (4,5)=3, (5,4)=5 regardless of branch 5. Column 5 analysis gave (1,5)=2, (3,5)=1, (7,5)=8 6. Box 7 forced (9,1)=1, (8,1)=7, (7,1)=2 7. A series of column/box intersections resolved all remaining cells <grid> 571623948 392748165 468915723 654839271 917562834 823174659 246381597 789456312 135297486 </grid> <confidence>100</confidence>
