Sudoku Killer Puzzles
How does one solve the ADVANCED killer Sudoku puzzles, where BASIC techniques don’t work.?
What I do is this.. Complete the obvious answers in ink. Go through all the usual methods to fill a few more squares in .. Then when all else seems to fail find where a square can be one of two numbers . Note which square this is and put one of the numbers in in pencil. Continue with the puzzle. If you then find this is wrong erase the pencil numbers , go back to the square with the first pencil No. and substitute the other number it could have been..again in pencil, continue with the puzzle. In a really difficult one you could do this more than once .It can still take ages but in most cases I can solve it .. I will be honest though I have been stumped a few times .
