I pasted your (updated) puzzle into Simple Sudoku,
and it reports these candidates and cell values:
- Code: Select all
*-----------------------------------------------------------*
| 16 16 8 | 4 2 7 | 3 9 5 |
| 5 9 37 | 6 1 38 | 278 4 27 |
| 34 2 347 | 38 5 9 | 6 78 1 |
|-------------------+-------------------+-------------------|
| 7 16 169 | 2 69 4 | 5 3 8 |
| 8 346 346 | 1 67 5 | 247 27 9 |
| 2 5 1349 | 378 789 38 | 147 17 6 |
|-------------------+-------------------+-------------------|
| 9 347 2 | 5 78 1 | 478 6 347 |
| 136 8 1367 | 9 4 2 | 17 5 37 |
| 14 147 5 | 78 3 6 | 9 1278 247 |
*-----------------------------------------------------------*
It looks like you are in a tough spot. According to SS,
you'll need to take several steps before you "solve" your
next cell. The first step: there is a naked pair in column 2.
The next several steps require recognizing "locked candidates."
(For example, the 7's in block 1 are locked in
column 3).
Then you'll need to spot another naked pair (in row 7).
Finally, after all that, you'll be able to find a hidden
single in column 2.
I hope this helps.
[Edit: the good news is that, as Karyobin suggests, the
puzzle is easy after you solve that next cell.]
