Another place to look is tutorial # 62 being uploaded in May 2020 Many of my players have mentioned that they are having problems with the X wing. Tutorial #62 gives a much more detailed look at the X wing....how to find it and what to do when you have found it.

For FAQ go to http://www.sudokuguy.com

The Xwing is used when you have a difficult puzzle and you have had to put all the possible small numbers in empty cells. This takes time. the challenge is to spot an Xwing. I must apologise in that at the beginning example I put in numbers in column one (36 and 169) which should have not been there..Please ignore them. Hang in there.
