I do not think the sudoku can be done if anyone can do it let me know how
you can use a solver which will solve but no idea how it gets the answers seems to me you have to guess on a few lines I have found no way of completing this one.

Perhaps you should bother to look at the other threads in this forum? and perhaps you should post the date and the number of the puzzle aswell?

There are already two threads about this puzzle. I strongly suggest you first look at both of them.

And the puzzle sure can be solved...

Pappocom asserts that all his puzzles are solveable with logic... and he's not been shown wrong yet. (OK, so the original post said without logic... whoops!)

Either look at the other threads about this puzzle, or try using one of the solvers that can show you how it was done.

I think you mean, he asserts that they're all solvable with logic alone!

ahem... thanks. I've corrected the post. Note to self: don't post when in a hurry.

It is soluble. You should reach a point where there are no obvious further solutions, but (amongst others) the first and fourth cells in the second column are both empty but either will accept 5 or 6 (but both have to be different). Trying 6 in the top row leads to a dead end. Trying 5 leads to a solution.

Mark,

That would be regarded as trial-and-error (T&E), and, while a perfectly valid technique, Pappocom's puzzles don't require it. There's always a solution available without resorting to T&E.

I have contacted other sudoku sites and they say this one can not be done with logic u have to guess or trial and error.
so not a true puzzle.

If it's a Pappocom puzzle, I think it's a case of you not knowing or understanding the logical to apply to it yet. We've all been there, and it's infuriating, but very satisfying when it finally clicks!

I already solved that puzzle seven times (please, don't make me solve it an eight time) in the process of helping people. I never guessed a single number.

Read the previous threads and the other hints....
