| 5       9       37       | 6       2       347      | 1       8       347      |
+--------------------------+--------------------------+--------------------------+
| 2       6       49       | 1       3       8        | 7       459     59       |
| 379     14      13479    | 2       479     5        | 349     6       8        |
| 379     5       8        | 79      6       47       | 2       1       349      |
+--------------------------+--------------------------+--------------------------+
| 379     14      14       | 379     8       6        | 5       2       379      |
| 8       37      379      | 5       1       2        | 349     3479    6        |
| 6       2       5        | 4       79      37       | 8       379     1        |
+--------------------------+--------------------------+--------------------------+


Seems I'm in for a long night ...

Thanks, Earl, great job!

edit: oops I just realized I posted almost the same grid (because I started without pencil marks ...) Embarassed The 3 in r1c8 goes away by this chain in "3"s: 18-14=36-96=98-18, thats a - ahem - skyscraper? no, turbot fish I guess.
