Can You Solve the Hardest-Ever Sudoku? - ABC News
Trying out an “expert” puzzle for the first time and I didn't get very far. The hint was to assume R6C2 to be 5 and then the next hint was to assume R7C8 to be 1. Does anybody know the logic in arriving at these hints? Thank you very much : r/sudoku
