PUZZLE NO. 308 : KROPKI PAIRS SUDOKU

 


RULES : Classic Sudoku rules apply. Additionally, if the absolute difference between two digits in neighboring 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 neighboring 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 not marked.
