I am stuck and neglecting husband and children, please can anyone help me get further with this one?

So far I have:-

8 1 9/7 3 2 9/7/5 9/6/5 4/5/6/9 5/4
9/7/3 9/7/4/3 6 9/7/5/1 4 8 9/5/1 1/5/9 2
5 2 4 9/1 6 9/5/1 8 7 3

7/6/3 8 2 7/5/1 5/3/1 4 6/5/1 1/3/5/6 9
9/7/6/3 9/7/6/3 5 2 8 9/7/1 4 3/1/6 7
4 9/7/3 1 6 5/3/1 9/7/5/1 2 3/5 8

1 5 8 4 9 3 7 2 6
2 9/7/4 9/7 8 1/5 6 3 9/5/4/1 5/4/1
9/6 9/6/4 3 5/1 7 2 9/5/1 8 5/4/1


Based on what I've read would I be correct in assuming in box 9 that I have a triplet of 541 so r9c7 is nr9?

Sudokus are fun... but don't neglect your family to play it! Just get them hooked on it as you are. Then you all can neglect one another. :D

r3c6 should be {1,9}. You have a 5 in there but that's not possible since you have a 5 at r3c1.

In box 5(r4c4-r6c6), 9 can ONLY go in column 6. So you can eliminate 9 from other cells in column 6. So r3c6 becomes 1.

But to answer your question about naked triple... no, that's not a naked triple because that's only true if 3 cells have ONLY numbers {1,4,5} combination in them. r8c8 also can be a 9 so the naked triple possibility is out the window. And it's not a hidden triple since 1 and 5 are also possible at r9c7.

Thank you chobans your hints really helped and I've got it finished now.
