## Naked Triples

Advanced methods and approaches for solving Sudoku puzzles

### Naked Triples

I have a row with the following values left:

Column1 = 1
Column2 = 4,9
Column3 = 6
Column4 = 3,4,9
Column5 = 3,4,7,8
Column6 = 7,8
Column7 = 5
Column8 = 5
Column9 = 2

Is there any Naked Triples in this row. I figure that 3,4,9 are a Naked triple in Columns 2,4, and 5. Is this correct?

You have two 5s in the row.

Column3 = 6
Column4 = 3,4,9
Column5 = 3,4,7,8
Column6 = 7,8
Column7 = 5
Column8 = 3,8
Column9 = 2

no, it isn't, as column 5 can also take other values.
anyway, only 5 cells are unknown,
so, if there is a trio, there's also a duo in the other 2 cells.

Ok dont quite understand what you are saying. Is there a way of eliminating any values in this row and if so what technique would be used?
