Yes, yet another newbie who's discovered the sudoku craze.

This one has got me stumped. Can any of you sudoku experts explain how I should proceed?

Oh, and I cannot fathom out that xwing business!

Take a close look at box 5. Then look at row 5, if you done a good job by looking at box 5 then you are able to fill in a number in that row...

[gasdoc]

do you mean the 4 in column 3 row 5?

Go on, explain the x wing thing properly then!!!

Thanks,

Paul

Completed it now - thanks again!

Don't you just hate it when you've missed something!
I must have been looking at that one for an hour until you gave me the hint & it was staring me in the face!

Concentrating on box 5 and row 5, I got the 4 in r5c3, and a 9 in r5c7.

But now I am stuck again. Any hints as to where I should look? I feel it might still be box or row 5, or I must be missing the obvious.

[Animator]

You are missing one obvious move... take a close look at the number 4 and after that the number 8, and after that again the number 4 and then the number 2.

(There also is a somewhat harder move involving the number 3)

Yes, the 4 and 8 were the obvious ones I was missing. Too many pencil marks on my page.
Thanks!
