Tough one!!
Sep 17 2008, 10:06 PM EDT
I've used all these techniques (except I'm not sure what the 7th technique was talking about). If this techinique could really help, I'd like some better explaining. I have a Mensa sudoku book that started easy and gets VERY hard. I am at #330 out of 600, and I am coming to where I cannot solve any more and was looking for a good tip on another method of figuring. If anyone knows an additional tip or could explain this 7th one, I would greatly appreciate it. Thanks.

Look at www.scanraid.com. Then look at the Sudoku solver. It will solve any Sudoku step by step so you can find out what you missed. Also there is a description of all the techniques.

Actually, that one is very simple. The column shown has five #'s missing, one of which is an 8. The 8 cannot fit in the bottom or middle spaces open in that column as the 8's across exclude those two spaces. Therefore, the 8 in the 1st column can only go in the top three spaces, and cannot be in the 2nd and 3rd column, top 3 spaces.
