This one has me stumped. I got this far with basics and an x-wing on 9s:
Code: |
+--------------+----------------+---------+
| 13 378 18 | 2 4789 89 | 6 34 5 |
| 23 9 26 | 46 5 1 | 8 34 7 |
| 67 4 5 | 3 78 68 | 2 9 1 |
+--------------+----------------+---------+
| 1234 23 7 | 1489 13489 289 | 5 28 6 |
| 234 236 269 | 5 348 7 | 1 28 49 |
| 8 5 129 | 146 14 26 | 3 7 49 |
+--------------+----------------+---------+
| 67 67 4 | 18 128 3 | 9 5 28 |
| 9 28 28 | 7 6 5 | 4 1 3 |
| 5 1 3 | 89 289 4 | 7 6 28 |

Play this puzzle online at the Daily Sudoku site
Although I wouldn't expect them in a puzzle rated hard, I used a couple of more sophisticated eliminations (a UR and xyz-wing), which got me here:
Code: |
+--------------+--------------+---------+
| 13 378 18 | 2 4789 89 | 6 34 5 |
| 23 9 26 | 46 5 1 | 8 34 7 |
| 67 4 5 | 3 78 68 | 2 9 1 |
+--------------+--------------+---------+
| 1234 23 7 | 19 13489 289 | 5 28 6 |
| 234 236 269 | 5 348 7 | 1 28 49 |
| 8 5 129 | 46 14 26 | 3 7 49 |
+--------------+--------------+---------+
| 67 67 4 | 18 12 3 | 9 5 28 |
| 9 28 28 | 7 6 5 | 4 1 3 |
| 5 1 3 | 89 29 4 | 7 6 28 |
+--------------+--------------+---------+

I can't see any other simple or not-so-simple eliminations. I'm afraid I'm going to end up a bit embarrassed when I find out, but what am I missing here? |

Thanks arkietech. Darn it, I knew I'd be embarrassed!
Seems like sometimes the "basics" cause me more grief than the hard stuff. |
