I read in the help guide that all puzzles can be solved without having to guess at an answer.

That pre-supposes that every puzzle, when fully kitted out with pencil marks has at least one square with just one pencil mark in it. Is this true, because I am working on one at present where this does not seem to be so?

If I’m wrong, someone please tell. Otherwise I’ll have to continue checking my pencil marks until I find a square which should have only one.

That is correct... no guesses are required...

And you don't nessesarily end up with one cell with only one pencil mark before you can fill in a number... for example when a row has only one cell where it can have the number 7 then that cell will most likely have pencil marks for others numbers too (although they are impossible since that cells has to be a 7)

(Also, if you are stuck, make sure to verify the starting-grid... (if you copied it))

Thanks very much. That is a big help. Seems I have a lot to learn about SuDoKu. One other, unrelated question. I have the option to include my signature ticked, and have set my signature in profile but it is not appearing. Any ideas anyone please?

Well to me sudoku is super interesting.
I write the numbers i needed onto a paper and cross out the ones witch i put down onto the sudoku. It is really easy sometimes but it takes time.
