PUZZLE NO. 68 : Kropki Sudoku



RULES : Classic sudoku rules apply. Additionally, if the absolute difference between two digits in neighbouring cells equals 1, then they are separated by a white dot. If the digit in a cell is half or double of the digit in a neighbouring cell, then they are separated by a black dot. The dot staying between 1 and 2 can have any of these dots. All possible dots are marked.
