|
|
This one has me stumped - another "diabolical" from a Sydney newspaper. I've added skyscrapers to my portfolio of techniques and even used one to get to this point. But now I'm stuck - do I have to learn yet another trick?
Code: |
+----------+---------------+-------------+
| 5 8 3 | 2 146 46 | 7 9 16 |
| 2 7 16 | 89 3 89 | 4 16 5 |
| 4 9 16 | 5 16 7 | 8 2 3 |
+----------+---------------+-------------+
| 7 5 24 | 46 8 146 | 1269 3 69 |
| 8 1 29 | 3 69 5 | 26 4 7 |
| 3 6 49 | 7 2 149 | 19 5 8 |
+----------+---------------+-------------+
| 69 3 7 | 1 5 2 | 69 8 4 |
| 169 4 8 | 69 7 3 | 5 16 2 |
| 169 2 5 | 4689 469 4689 | 3 7 169 |

All help gratefully received. |

Take a look at 9 in R4 and B6.

I just knew that I was missing something obvious like a hidden pair or a box-line interaction. How annoying.
Many thanks Keith. |
