The end of its reply
I solved it by hand, using single-candidate and elimination steps. Where a cell had two possibilities, I tried one and discarded it when it led to a contradiction. I then checked that every row, column and box in the final grid contains each digit exactly once. <grid> 497158623 261943875 358267149 743892516 529671438 816534792 184325967 935716284 672489351 </grid> <confidence>97</confidence>
