1. A9=9
2. Double Exocet : Base Cells (abcd)A12, Target Cells B8.C6 and Base Cells (abcd)C79, Target Cells A6.B1, (abcd)Columns168 where {a,b,c,d}={2,3,4,6} :
2a. Structure of the 1st band :

A| 1 ab ab | 5cd 5cd cd | 7 8 9 |
B| cd 5 cd | 78 78 9 | 1 ab ab |
C| 7 9 8 | 1ab 1ab ab | cd 5 cd |

2b. The Multifish (2346)Columns168 excludes (246)D23579, (6)E3, (34)G2579, (23)H2347.

The puzzle is now "solvable" or ...

GH1=45 -> contradiction
GH1=43 + 2 solutions of the 9s -> contradictions; 32 Singles
[(1=7)H3-7F3=NT(781)BFJ4]-1H4; Singles to the end.


Each week a new 'unsolvable' will be published and the previous will be accessible here from this archive section. If you like very tough puzzles, these are for you.
Share and Enjoy
