The end of its reply
I solved it by logical deduction. After finding the forced cells in the middle band, I assumed r6c7 = 7, which led to a complete valid grid. I did not separately prove the other case (r6c7 = 5) impossible. I checked the finished grid against every row, column and box, and it matches all the givens, and the puzzle is stated to have a unique solution. <grid> 162854379 974613582 583792614 417526938 835971426 629438751 358269147 746185293 291347865 </grid> <confidence>97</confidence>
