Remove <3> from r3c3 to solve
If x=3, ab=<17>, c=6, de=<34>, f<>3, b=3
Or, you could see it as whatever you put in c <16>, b must be <3> |

Thanks for the puzzle immp! After basics:
| Code: | +-----------------+---------------+-------------+
| 5 d24 9 | e34 8 7 | 6 1 23 |
| a17 c12*6 137 | 5 f123 b16 | 9 8 4 |
| 148 12468 138 | 346 123 9 | 5 7 23 |
+-----------------+---------------+-------------+
| 27 9 27 | 8 6 3 | 4 5 1 |
| 6 158 18 | 9 15 4 | 3 2 7 |
| 3 15 4 | 2 7 15 | 8 6 9 |
+-----------------+---------------+-------------+
| 19 7 15 | 36 359 56 | 2 4 8 |
| 489 48 6 | 7 49 2 | 1 3 5 |
| 24 3 25 | 1 45 8 | 7 9 6 |
+-----------------+---------------+-------------+
|
Then I used the chain: 1r2c1-(1=6)r2c6-(16=2*)r2c2-(2=4)r1c2-(4=3)r1c4-(2*3=1)r2c5 contradiction => r2c1 <> 1; stte. |
