I've always been able to solve puzzles on this site with wings (X, XY and XYZ). But I am stuck on today's at this point:
Code: |
+---------------+-------------+------------+
| 39 4 2389 | 123 123 6 | 18 7 5 |
| 35 258 238 | 7 123 9 | 18 4 6 |
| 6 7 1 | 4 5 8 | 3 2 9 |
+---------------+-------------+------------+
| 1 58 68 | 28 4 257 | 267 9 3 |
| 2 9 48 | 38 6 37 | 47 5 1 |
| 7 3 456 | 25 9 1 | 246 8 24 |
+---------------+-------------+------------+
| 34 1 7 | 9 238 23 | 5 6 248 |
| 8 6 259 | 125 127 4 | 29 3 27 |
| 3459 25 239 | 6 378 235 | 249 1 2478 |
+---------------+-------------+------------+
|
Does this puzzle require some other technique or have I just lost it? If the latter, please break the news to me gently
Cheers |

You have missed a hidden pair, not too important, and an xy-wing. (Important.) |

As one who doesn't see hidden pairs, I see them as their complementary subsets, in this case a naked quint.
As to the XY-Wing, I had three candidates in the pivot cell but it worked as an XYZ-Wing for a one-step solution. |

I did not use the hidden pair/naked quint, but an x-wing (5) r68c34, which opened an xy-wing 58-28-25 in boxes 4 and 5. |

Thank you all. Obviously my brain was still numb during this morning's cuppa. A fresh look now after a day of 'cut and thrust' in the office and the XY wing leapt off the page.

Used an x and xy wing but it took a while. I'm still a bit shaken up by traumatic events of past week. My daughter married an American ! |

You reared her, so look in the mirror for the blame. |
