As I said in my previous post that currently I am trying to create Converse Logic Sudoku puzzles. I have recently created Consecutive Sudoku, Average Sudoku, Kropki Sudoku etc which are converse logic Sudoku puzzles. Now its turn to put Kropki Sudoku. I am also try to create some puzzle in which I don't need to give even a single digit. Kropki Sudoku falls into this criteria. Kropki Sudoku puzzles can be created without putting any hint. I created four Kropki Sudoku puzzles. Out of these four puzzles, three Sudoku could be solved without putting any single digit. However I liked the 4th one which follows complex logic from all the directions to put digits in certain cells. It has beautiful logic to solve it. However at the end I found that I need to give one hint to avoid it being non-unique puzzle. I gave the hint but if I was give another symmetrical hint to maintain the looks of the puzzle, then the whole logic to solve this puzzle was getting overshadowed. So here in this puzzle, I scarified symmetry of the puzzle to maintain good logic. Hope you will like this puzzle as much as I loved create this one.
It is after the gap of around 7 years, I have created back Kropki Sudoku puzzle. That time this puzzle type was known as Dots Sudoku. Earlier puzzle is posted with title Kropki Sudoku (Fun With Sudoku #3). Soon I will be posting remaining three Kropki Sudoku puzzles which are much easier than this puzzle.
This Kropki Sudoku, I am posting in Daily Sudoku League as 127th Sudoku in this series.
Rules of Kropki Sudoku
Classic Sudoku Rules apply. Additionally if absolute difference between two digits in neighboring cells equals 1, then they are separated by a white dot. If the digit is a half of digit in the neighboring cell, then they are separated by black dot. The dot between 1 and 2 can be either white or black.
