Maybe you are here: Code: | +----------------+----------------+----------------+
| 17 8 4 | 3 126 12 | 67 9 5 |
| 17 5 6 | 9 14 8 | 47 2 3 |
| 29 3 29 | 46 7 5 | 8 1 46 |
+----------------+----------------+----------------+
| 25 9 3 | 25 8 4 | 1 6 7 |
| 6 4 1 | 7 25 9 | 25 3 8 |
| 8 7 25 | 1 3 6 | 25 4 9 |
+----------------+----------------+----------------+
| 3 1 8 | 2456 9 27 | 46 57 246 |
| 459 2 579 | 4568 1456 17 | 3 578 146 |
| 45 6 57 | 2458 1245 3 | 9 578 124 |
+----------------+----------------+----------------+ |
Look at the Help section of the site to learn how to format a puzzle:

This is not easy. A first step is a double W-wing 46 that takes out 46 in R6C4.
Actually, that turns out to solve the puzzle!

I think you mean r7c4. It can also be viewed as two simple coloring chains, one each on 4 and 6. |

Marty,
Yes. R7C4. There is nothing special about this WW wing. It can also be seen as two skyscrapers in 4 and in 6 or, as you say, a couple of short coloring chains that both go through B23.

Hi Marty & Keith,
Thank you for your help, not only with the puzzle but on how to format one. I will have to look up the W wing. I had thought that it was the same as the WXYZ wing.
I am amazed that you were able to read my puzzle. It was such a mess. You even got to exactly where we were in it.
I couldn't help but notice the 25s on boxes 4, 5, and 6. I was wondering if they meant anything. |
