Today’s Sudoku is quite tough I think. It has a really narrow path with some really tricky deductions on the way. Still, I like the logic as well as the appearance I got working here.
Rules – Follow regular Sudoku rules. Additionally, each shaded cell must have repeating orthogonal neighbours (neibhbours sharing an edge). White cells must have distinct orthogonal neighbours.
Enjoy!
