I got to where I only had about 12 boxes left and got stuck. I finally realized the trick to solving the last boxes was applying all the rules to the possible solutions of those boxes. Tricky!

There must a rule that I am not aware of to solve the last 12. Would be nice to know what it is so that I can use it in future

For me it was this rule: if there are in ohne field only two boxes left with 4,one next to the other, then in none of these boxes can be a 6. It's the same with 1 and 4, 3 and 7 and so on.

Yep, that was it for me, too! Since there are two boxes left in the bottom-right corner, and one of them had to be a four, neither of the boxes could be a six.

Thanks folks. Brain was not in gear. I was using that rule once I had allocated a number. I just did not apply it to the pencil marks. Doh!!!!!

Key

  • A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
  • Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
  • If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
  • Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
