Is there any way to find another number on this puzzle without guessing? I made a few guesses and got it to work, but I can't seem to apply any technique or make up my own to avoid guessing.
Here is the original puzzle:
- Code: Select all
+---+---+---+
|..8|.9.|...|
|.5.|82.|7..|
|...|..1|.6.|
+---+---+---+
|3..|...|.7.|
|7.2|3.4|8.1|
|.1.|...|..5|
+---+---+---+
|.7.|4..|...|
|..4|.62|.8.|
|...|.8.|6..|
+---+---+---+
I've 'solved' it up to this point:
- Code: Select all
+---+---+---+
|.48|79.|...|
|.5.|82.|7..|
|..7|541|.68|
+---+---+---+
|385|219|476|
|762|354|891|
|419|678|..5|
+---+---+---+
|876|435|...|
|..4|.62|.87|
|...|.87|6..|
+---+---+---+
With the following options table:
- Code: Select all
+--------------------------------------------------+
| 126. 4... 8... | 7... 9... 36.. | 1235 1235 23.. |
| 169. .... 13.. | 8... 2... 36.. | 7... 134. 349. |
| 29.. 239. .... | 5... 4... 1... | 239. 6... 8... |
+--------------------------------------------------+
| 3... 8... 5... | 2... 1... 9... | 4... 7... 6... |
| 7... 6... 2... | 3... 5... 4... | 8... 9... 1... |
| 4... 1... 9... | 6... 7... 8... | 23.. 23.. 5... |
+--------------------------------------------------+
| 8... 7... 6... | 4... 3... 5... | 129. 129. 129. |
| 159. 39.. 4... | 19.. 6... 2... | 35.. 8... 7... |
| 1259 239. 13.. | 19.. 8... 7... | 6... 345. 34.. |
+--------------------------------------------------+
Can anyone explain how I can get a bit further without guessing?
It seems like there is something to the 239's in col 2 and row 3, but can't seem to figure it out.
Thank you!!!
