Repeated Neighbours Sudoku is a very interesting Sudoku type in which whenever numbers repeat in the orthogonal cells of a cell, then this cell is greyed. To solve Repeated Neighbours Sudoku, first one should try to find out which of the Neighbour cells could be repeated. Try to concentrate on the grey cells which are on the edge of the grid, as these cells will immediately give as the cells having repeated numbers. Another thing to solve the Repeated Neighbours Sudoku is to take care of the converse rule. It means any cell that is NOT greyed cannot have the number repeated on its orthogonal cells.

Rules of Repeated Neighbours Sudoku

Place a digit from 1 to 9 in each empty cell so that each digit appears exactly once in each row, column, and outlined region. Each shaded cell must have repeating orthogonal neighbours (neighbours sharing an edge). White cells must have distinct orthogonal neighbours.
