Not sure where to go from here

Postby kikosanchez » Wed Nov 21, 2007 7:34 pm

So I've been stuck on this for awhile. It is a Hard from Pappocom.


o5o 29o 38o
oo3 oo8 6oo
o8o 63o 97o

1o8 3oo 596
oo5 8o6 2o7
o67 ooo 4o8

o3o o8o 74o
8o4 o6o 1o3
ooo 423 86o

It would be great if this I could just get the next (1) step explained in layman's terms. Thanks for any help.

Hi welcome to the forum,

the next step is to pencil in the remaining candidates like this:
Code: Select all
.---------------------.---------------------.---------------------.
| 467    5      16    | 2      9      147   | 3      8      14    |
| 2479   12479  3     | 157    1457   8     | 6      125    1245  |
| 24     8      12    | 6      3      145   | 9      7      1245  |
:---------------------+---------------------+---------------------:
| 1      24     8     | 3      47     247   | 5      9      6     |
| 349    49     5     | 8      14     6     | 2      13     7     |
| 239    6      7     | 159    15     1259  | 4      13     8     |
:---------------------+---------------------+---------------------:
| 2569   3      1269  | 159    8      159   | 7      4      259   |
| 8      279    4     | 579    6      579   | 1      25     3     |
| 579    179    19    | 4      2      3     | 8      6      59    |
'---------------------'---------------------'---------------------'

Then check the grid for Locked Candidates.

Thanks, I thought I could see the solution without actually penciling it all in, but doing this definitely helped. Ends up r8c2 had possibilities of 2,9, but either r7c3 and r9c3 had to be a 9, so r8c2 was 2 and it was very easy from there.
