If you use the "code" open and close tags then the puzzle will look like:
Code: Select all
5 . . | 4 . 6 | 7 . . |
. . . | 5 . . | 9 . . |
2 . . | . 1 7 | . 4 . |
----------------------
. . . | 7 2 . | . 1 . |
9 . . | . . . | . . 8 |
. 7 . | . 6 8 | . . . |
-----------------------
. 3 . | 2 7 . | . . 5 |
. . 4 | . . 3 | . . . |
. . 2 | 6 . 4 | . . 3 |

which is more readable. Mostly the solution involves naked and hidden singles, but there is also a naked pair and a locked candidate that show up. To find out more about these try
(I used the "list" tags for the above). As far as a next move, there are 2's in columns 4 and 5 and clues (numbers provided in the puzzle) in box 2 (the top middle set of 9 numbers) rows 1 and 3. This means 2 can only go in row 2, column 6. Other naked singles are found similarly.

Hi christina and welcome to the Forum,

Mike has helped you out above with much the same as I was about to post. You might also like to click on HERE to read up on the Forum's procedure for posting puzzles and the Terminology used.

It seems you have just started to learn about Sudoku in which case you should also find this link helpful (just click on it):

I found your above reference to the "unique rectangle" thread certainly interesting but hopefully christina will consider the simpler "basic" steps as mentioned by Mike above which will enable this puzzle to be solved.

thanks for your help

thanks for all your help. I guess I need to read up on my Sudoku lingo, because I had no idea what half of the stuff meant. lol. I have never had to ask for help before, so I didnt know how technical it got!
Anyways, I had gotten about 17 of the numbers before I got stuck. I put it down for a couple of hours, then erased all my numbers and started again, and finished it last night.
Thanks for the help though
