The end of its reply
I solved it by hand, using candidate elimination and placing forced cells one at a time. I did not run a program. Two spot checks passed: the columns each contain 1–9, and the rows I rechecked do too. One branch (R1C7=5) led to a contradiction, which forced R1C7=4. <grid> 726189453 158347692 943526178 681435927 297618534 435792861 369874215 872951346 514263789 </grid> <confidence>96</confidence>
