Two steps: x-wing (1), xy-wing (269).
Any one-step solutions?

Not from me. I obviously missed something, or a lot of things, since it took me six steps. So I erased it, did it again and it took me seven!! |

Actually, I used the x-wing(s) on <1> and an ER on <4> before finding the <269> xy-wing. So I started again and just used the xy-wing - and found that was all that was needed. Seven steps indeed!! |

After basics, I had this code: Code: |
*--------------------------------------------------*
| 1 5 49 | 6 79 3 | 478 2 478 |
| 8 49 6 | 5 79 2 | 347 1 347 |

|----------------+----------------+----------------|

| 4 69 5 | 3 26 7 | 1 89 28 |
| 3 169 179 | 129 126 8 | 27 4 5 |
|----------------+----------------+----------------|
| 9 2 18 | 178 3 4 | 678 5 678 |

| 6 7 48 | 28 5 9 | 24 3 1 |
*--------------------------------------------------* |
My solution was exactly like that posted by Earl. The x-wing <1> to eliminate <1> in r6c34 which opens up the xy-wing <269> with pivot <27> at r6c7 and pincers <79> at r4c8 and <29> at r6c4 to solve the puzzle.
How did you eliminate the <1> in r6c4 or did you use a different xy-wing <269>?

Well - there wasn't a <1> there after I rubbed out the first attempt and did it again. The rubber (or eraser to you guys) must have slipped. |

I solved it the same way everyone else did but didn't count the # of steps!
I enjoyed today's puzzle more than other VHs recently because it didn't just fall apart like some do -- it took some methodical work. But not too much! |

I am puzzled with others saying that the xy wing was <269>. Can a <269> xy wing pivot on something with a 7 in it?
I am thinking that the xy-wing should be <279>. |

I thought that it was a fun puzzle. We solved it with one x-wing and the 269 xy-wing. For my husband and I, these puzzles have been fun lately. Good practice too with the xy-wings.
There have been more VH puzzles than usual in the last week or so. |

Aha! There is a 269 xy wing and a 279 xy wing. I never saw the 269 wing. Either solves the puzzle. |
