### Puzzled by another puzzle

This is from the pappocom computer program and is labeled hard. Also, I have been unable to find instructions on the site for using the bbcode to post my puzzles. Any instructions would be appreciated. Here's my puzzle:

2---1---3---6789---5---6789---679---4---69
79---6---5---1279---127---4---3---17---8
789---4---78---13679---17---13679---1679---5---2
3---9---4---127---6---127---8---17---5
1---8---67---4---9---5---67---2---3
67---5---2---178---3---178---1467---9---46
56---2---1---357---8---37---49---36---49
4---3---9---126---12---126---5---8---7
568---7---68---359---4---39---2---36---1

Thanks. Donetta

Hi Donetta

In row 3 you have a hidden triple = 1,3,6. These 3 numbers must go in only 3 cells therefore delete all other numbers in those cells.

This will allow you to place the other numbers in row 3.

Can you proceed from there?

Look at the sticky 'How to Ask for Help' at the top of this section of the forum for how to post a puzzle grid. Click here if you cannot find it.

One other thing to remember is to make sure that the box "Disable BBCode" is UNCHECKED.

There is a box2 Column 5 elimination of 7s, that should solve the puzzle

### Thanks

I solved the puzzle by eliminating the 7's in box 2. I have a question about sweetbix's post regarding the hidden triples. I'm relatively new at this, so I'm just a bit confused. About the 136 hidden triple, there is a 17 in a fourth cell; I thought the numbers for the hidden triple needed to be in three cells and only three cells. Since there is a one in a fourth cell, can there still be a triple with the 136?

Thanks both for your responses and help. I do appreciate it. I love sudoku and love learning more and more about the details.

Hi Donetta,
I agree with you that this was not a hidden triple as the three numbers did occur in four cells. When submitting future puzzles I would suggest that you post both the original puzzle and also the stage you have reached. This enables readers to know whether you have made a mistake in getting as far as you did.
I was looking at this thread and I was curious how you eliminated the candidate 6's from cells r9c4 and r9c6 when submitting your post?

Thanks Cec for noticing my mistake with the triple. Sorry for putting you wrong. Luckily Donetta iwas able to solve despite my mistake.

I assume the 6s were deleted from r9c4 and r9c6 because of the triple 126 in box 8. Hope I got it right this time!

When you click to reply to a message, at the bottom of the text screen is the options where it states 'BBCode is ON' if you click on BBCode or the link here you will find out how to use BBCode.
