The end of its reply
I solved it by hand, using forced placements and elimination. I did not run a program on it, but I checked the finished grid row by row and column by column. The key opening deductions were: - Box 5 forces r6c6=5 and r5c6=2. - Box 4 then gives r4c2=8, r5c3=7, r6c3=6 and r6c2=9. The rest followed from the remaining rows, columns and boxes. <grid> 749821653 613457289 258936417 582793146 137642895 496185372 374219568 921568734 865374921 </grid> <confidence>97</confidence>
