Hi All,
I am a firm believer in not adding numbers in and "trying" numbers and seeing if they work.
I am a fairly new starter at all these puzzles but I am stuck on this one.
I have entered a few numbers and can now not logically see any advancement to be made (without the try it and see method). I have put this puzzle in several sudoku solvers and asked suggestions and they all say - no next move can be calculated.
How do I go on from here! I have solved the puzzle by trial and error but that isnt the way they should be done.
I was going to paste the image in here but havent a URL for it so here is how far I have got
| Code: | 6-2 --- 198
-4- -9- -36
3-- -6- --4
--- -73 -4-
--- 1-6 ---
-8- 25- -1-
825 -1- -63
937 62- -51
164 --- 9-- |
please can someone explain how I progress - thanks a lot
Michael!!! |

You're at EXACTLY the same place as I am. I tried DRAW and it said 3 in row 1, col 4, but I do not understand the logic as to why a 3 is suggested. Can someone PLEASE help (what about you fiendish Daily Sudoku setters??)
Cheers

Well, there's only one of me!
| Code: |
6-2 --- 198
-4- #9* -36
3-- #6* --4
--- $73 -4-
--- 1-6 ---
-8- 25- -1-
825 -1- -63
937 62- -51
164 --- 9--

The $ cell must be an 8 or a 9. The only places in the top middle box that the 1 and 2 can go in are the *-ed cells. This means that the 8 has to go in one of the #-ed cells, so the $ must be the 9.
Not sure why the clue for this one isn't the next step -- I guess I'll have to sort that out!

Brilliant. It had just finally struck me about the two 12 687 cells.
Thanks for excellent help and a very good brain work out.
