PUZZLE NO. 201 : 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.

  2. Nice variant Akash. Thought it would be easy because of the absence of converse rule. But was tougher than I thought. Took about 21 mins. Thankyou bhai.

    1. Most welcome Ravi. It does tend to get harder because of the absence of the converse rule.
