The end of its reply
Looking at this puzzle, I'll work through it systematically using constraint propagation and logical deduction. **Key deductions:** - (9,5)=6 (only value in box 8 for col 5), cascading to fill (7,5)=2, (8,5)=7 - (4,2)=4 (only value for box 4/col 2/row 4 intersection) - (4,6)=8 (only cell in box 5 that can hold 8), then (5,5)=3, (6,5)=1 - (3,1)=9 (forced by col 1 constraints) - (1,3)=7 (resolves box 1 placement), leading to (5,4)=6, (6,4)=4 - (7,7)=6 (forced by box 9), then (9,7)=4, (6,7)=8 - Remaining cells fill through elimination <grid> 127986534 536147982 984253167 641798325 298635741 375412896 753824619 469371258 812569473 </grid> <confidence>100</confidence>
