Can Consecutive Sudoku be created without giving any hints on the grid like the Kropki Sudoku Puzzles. The answer is NO. It is because one can reverse the 1-9 to 9-1 to get the same layout of puzzle i.e. 1 can be replaced with 9, 2 can be replaced with 8 and so on till 9 can be replaced 1. Once this exercise is done, we will get the same grid pattern for Consecutive Sudoku puzzle. It means that any Consecutive Sudoku which does not have any givens will have at least 2 solutions.
Now the next question is, can Consecutive Sudoku be created with only one hint given in the grid. The answer is YES if that given number is not 5. It is because if the given number is 5 then again the given grid will have at least two solutions.
I have tried to create the Consecutive Sudoku puzzle with just 2 given. This is the tough Sudoku and will take time to put first few digits conclusively. Once few digits are put, then this Sudoku can be solved easily.
Today's puzzle is tough one and it will take around 9 minutes for an experience player to solve it.
This Consecutive Sudoku I am posting in The League of Extraordianary Ladies & Gentlemen as 205th Sudoku puzzle in this series.
