Converse Ruled Sudoku puzzles are one of my favourite Sudoku types and Repeated Neighbours Sudoku is one of the Conversed Rules Sudoku. This page is for indexing all these Sudoku puzzles of this type. Links to the Sudoku puzzles of this type is given below.
Repeated Neighbours Sudoku is 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 Repeated Neighbours Sudoku is to take care of converse rule. It means any cell which 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.
