This is embarrassing, but...I cannot make this puzzle work. It's only a hard, which usually goes pretty smoothly for me, and it doesn't seem especially tricky as I work my way through it. But I've started fresh half a dozen times, and each time I get to the home stretch, I end up with an unsolvable error.

(Sorry, I don't speak Sudoku, so I don't know how to describe my efforts in terms of whirligigs or west wings or flying escargot.)

I'm sure there's nothing wrong with the puzzle, so just tell me--uh, is there anything unusual about this one? Or do I just need to get lots and lots of sleep?

thanks--
agv

I didn't notice anything out of the ordinary with this puzzle. If you post your position, someone can help you out.

Welcome to the forum.

agv,

Is this where you are stuck?
Code:
+-------------------+-------------------+-------------------+
| 169   469   146   | 8     5     2     | 46    7     3     |
| 67    456   2     | 9     3     67    | 8     456   1     |
| 1678  4568  3     | 147   1467  167   | 456   9     2     |
+-------------------+-------------------+-------------------+
| 5     2     1467  | 147   8     3     | 9     146   467   |
| 178   48    147   | 6     2     9     | 1457  3     457   |
| 1367  346   9     | 5     147   17    | 1467  2     8     |
+-------------------+-------------------+-------------------+
| 269   1     56    | 27    67    8     | 3     456   45679 |
| 4     369   8     | 137   167   5     | 2     16    679   |
| 236   7     56    | 123   9     4     | 156   8     56    |
+-------------------+-------------------+-------------------+

You need to find a pair in R2, a pair in C3 and B7, and a triple in B9.

Before this point, and after, it is all singles.

I hope this helps.

Keith

Thanks, Marty! Hi, Keith--

No, that's not exactly it. I'd eliminated a bit more clutter, but somewhere I must have been having a brain fa- er, froot loop. On my fifteenth or sixteenth attempt, everything just followed normally and I got to the end of it. I must have been making some flying leap in logic somewhere. (...and then a miracle occurs...)
