Thanks for the puzzle immp! Here's the grid after basics:
Code: | +--------------+---------------+---------------+
| 9 178 178 | 3 4 5 | 78 6 2 |
| 2 5 378 | 89 6 1 | 3789 4 379 |
| e38 4 6 | f89 7 2 | 3589 g589 1 |
+--------------+---------------+---------------+
| 4 237 379 | 1 23 8 | 579 h579 6 |
| 1 78 789 | 45 59 6 | 2 3 479 |
| 6 23 5 | 7 23 a49 | 4-9 1 8 |
+--------------+---------------+---------------+
| d37 13 134 | 2 8 b49 | 6 c7*9 5 |
| 5 9 48 | 6 1 7 | 348 2 34 |
| 78 6 2 | 45 59 3 | 1 789 479 |
+--------------+---------------+---------------+
|
Then I used the chain 9r6c6=r7c6-(9=7*)r7c8-(7=3)r7c1-(3=8)r3c1-(8=9)r3c4-(89=5)r3c8-(57*=9)r4c8 => r6c7 <> 9; stte. |

Nice one Immpy!
I used the <23> UR in r46c25 to give r4c2 = 7 to solve |
