    I love these killer ones. I used to do the one in the Times everyday on the train. I did learn a few hints that helped me.

    Each line (vertical and horizontal) and square (3x3) totals 45.

    Each 3x3 sqaure will contain each number 1-9 so for example bottom right square the only place a 9 could fit would be in the dotted area of 24 as it can't go in the dotted area of 8, 5, 9 or 10.

    Good luck

    Well this might get you started

    Damn.

    I'm not going to look at your entire result just yet, but take one clue and look at it again during the day. I'm curious to know where my logic fell apart!

    Cheers.

    Are you any good at Killer Sudoku?

    Hey. Recently I've had a bit of a passion for these games, and print them off to do on the train on the way home to pass the time. I've been visiting a site where they have loads of these, and I'm currently working my way through the easy ones, which generally take me between 30mins to an hour to complete.

    I'm not a big maths person, but have decent logic (I should hope so anyway as I'm an IT contractor...), but there's one supposedly easy one which I simply can't do. In fact, as far as I'm concerned I have proved that it can't be done. I'd be intruiged to see if any of you clever bods can do it...

    It's No.381, at the top of this page...

    In my opinion, there is no combination that will fit in the bottom two rows given the other combinations above them to the right.

    Anyway, anyone fancy a go?!

Working...
