There are no 8s in this puzzle, hence the 8 in most cells - some are in pairs and in threes, not sure how to do deal with them? what next?

There's no general problem with a sudoku not having one number present in the clues, nor any particular way to attack that type (that I know of). This puzzle specifically, though, is a different matter. There's certainly nothing simple to do, though it can be solved with the extreme methods that make my head hurt.

Consider naked triple in row 4

Hi Paul,
Thanks for your reply.
Su Doku puzzles with one number not present are not a problem, my comment was only a bit of information. However, I would like to learn how the tuckle these more difficult puzzles and know which method to apply.

Could you post the original - it looks a bit odd in R4.

Should it look like this?

Code: Select all

 [278]  [248]  [578]  [589] 61 [4578] 3 [45789]
693274 [158]  [18]  [58]
1 [48]  [578]  [589] 3 [58] 26 [45789]
 [378]  [38]  [6789]  [3578]  [458] 2 [34568]  [489] 1
 [238] 5 [68] 1 [48] 9 [3468] 7 [2468]
4 [1238]  [1789] 6 [58]  [3578]  [358]  [289]  [2589]
962 [578] 1 [578]  [478]  [48] 3
 [38]  [138]  [18] 42 [3678] 95 [678]
574 [38] 9 [368]  [168]  [128]  [268]


cos if it does - it falls apart very easily.

I'm hoping that your original transcription was slightly out - either that or my head is.

I see that over at the end of Row 4 you show a 489. That is the only mention of a 9 for that row, so it must be good. Go from there.

I'm new at this, so don't crucify me if I have the logic wrong.
