Considering the pair 29 in col8 and the triple 149 in BOX 4 or Col3, the grid after basics
Code: |
+-------------+--------------+-----------+
| 8 2 19 | 13 137 6 | 79 5 4 |
| 3 149 149 | 18 5 178 | 279 2-9 6 |

| 6 49 23 | 358 39 358 | 2349 7 1 |
+-------------+--------------+-----------+
| 5 3 6 | 7 4 2 | 8 1 9 |
| 149 7 149 | 135 8 13*5 | 456 46 2 |
| 2 14 8 | 9 6 1*5 | 45 3 7 |
+-------------+--------------+-----------+

A net
(9)r2c2 = r6c2 - (9=3)r6c5 - r4c6 = (3*)r8c6
............ǁ
.........(9-4)r6c2 = r6c7 - (4=5)r9c7 - (5=1*)r9c6 - (1*3*=7)r4c6 - r2c6 = r1c5 - (7=9)r1c7 => -9r2c8; stte |

Rewriting Clement's solution :
Code: | +-----------------+-------------------+----------------+
| 8 2 1-9 | 13 13(7) 6 | (79) 5 4 |
| 3 14(9) 149 | 18 5 18(7) | 27-9 2-9 6 |
| 7 6 5 | 4 2 9 | 1 8 3 |
+-----------------+-------------------+----------------+
| 149 8 37 | 2 1379 (137) | 3469 46 5 |
| 19 5 237 | 6 1379 4 | 239 29 8 |
| 6 (49) 23 | 58 (39) 58 | 239(4) 7 1 |
+-----------------+-------------------+----------------+
| 5 3 6 | 7 4 2 | 8 1 9 |
| 49 7 149 | 135 8 135 | 456 46 2 |
| 2 14 8 | 9 6 (15) | (45) 3 7 |
+-----------------+-------------------+----------------+
| Kraken Cell (137)r4c6 -> [9r2c2==9r1c7]-9r1c1.r2c78=9r1c7; stte
||1r4c6-(1=5)r9c6-(5=4)r9c7-4r6c7=(4-9)r6c2=9r2c2
||3r4c6-(3=9)r6c5-9r6c2=9r2c2
||7r4c6-7r2c6=7r1c5-(7=9)r1c7 |
