Repeated Neighbours
Solve online in F-Puzzles (thx bbutrosghali!)
Place the digits from 1 to 9 in every row, column and 3x3-block. All cells having the same digit(s) more than once as orthogonal neighbours are shaded. (If a cell is not shaded, it cannot have any digits repeated as orthogonal neighbours.)
Solution code: Row 9, followed by column 4.
