RULES : Classic Sudoku rules apply. A grey horizontal or vertical bar symbol in a cell indicates that the digit in the cell is equal to the difference of its horizontal or vertical neighbours. Not all possible bars are marked, i.e. cells without a bar may or may not indicate the difference of its horizontal or vertical neighbours.
