Kent,

Look for the naked triples in box 7 and row 9.

[Kent]

Which are the naked triples? Which can u eliminate?? Can't really see it.

Kent,

Here is the candidate grid:

Code: Select all

2378    12378 1378 | 76  76    4   | 23    9  5
2347    2347  37   | 9   5     1   | 23    6  8
6       5     9    | 2   3     8   | 1     4  7
-------------------+---------------+-------------
78      9     1678 | 3   1467  67  | 468   5  2
23      1236  4    | 8   16    5   | 9     7  16
5       1678  1678 | 467 9     2   | 468   3  146
-------------------+---------------+-------------
-479   *467   2    | 467 8     679 |  5    1  3
1      *467   *67  | 5   2     3   |  467  8  9
-34789 -34678 5    | 1   #467 -679 | #467  2 #46

The starred(*) cells and the sharp(#) cells both form naked triples. The cells with a (-) can have 4,6 and 7 removed from them.
