|

I have got to the following stage for the Daily Sudoku, Sat 20-Aug-2005:
3,9,* | 8,*,5 | 6,*,*
*,*,* | *,*,* | *,*,5
4,5,8 | *,9,* | *,*,*
---------------------------
*,8,4 | 3,*,2 | *,*,*
2,*,9 | *,5,* | 1,*,4
*,*,* | 9,*,4 | *,2,*
---------------------------
9,*,* | *,2,* | 7,5,8
7,*,* | 5,*,* | *,*,*
8,*,5 | *,*,9 | *,3,6
The hint facility of the solver suggests a '3' in the centre square of the middle left 3x3. I am hesitant to use this as I cannot justify it. Any suggestions or methods with explanation would be appreciated. I think I am being a little impatient and ought to put it down and come back to it later, but I couldn't resist asking.
(A little background, I only discovered Sudoku puzzles on Wednesday via the Independent UK newspaper, 17-Aug-2005, completed their Quick, Elementary, Intermediate and advanced puzzles and came online to find my next fix. I am not familiar with the names of strategies or methods used to solve such puzzles, but no doubt, I have employed some of them in solving the 4 puzzles I have already come across. Hence, please pad out any references to strategies with a little explanation, thanks!) |

I don't know why I didn't realise it myself. It's so obvious now, it's embarassing.
I blame it on the lack of breakfast.
Thank you!! |
