Puzzle No. 415 : Repeated Neighbours Sudoku [Daily League]

Firstly, PDFs!

Week 25.

Week 26.

Remember that you can solve the puzzles from the League online on the Sudokucup Guest League page with a 24h delay.

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.
