This puzzle has been great fun so far but after NINE separate VH steps, seven of which were deletions on digit <5>, I have still not completed the !?*% thing. Here is where I am at presently.
Code:

 *-----------------------------------------------------------*
 | 27    3     5     | 1     4     6     | 278   9     78    |
 | 4     1     279   | 39    8     379   | 237   5     6     |
 | 8     67    679   | 2     57    3579  | 37    1     4     |
 |-------------------+-------------------+-------------------|
 | 17    8     34    | 34    57    2     | 15    6     9     |
 | 9     5     467   | 68    1     47    | 78    3     2     |
 | 167   2     367   | 68    9     357   | 15    4     78    |
 |-------------------+-------------------+-------------------|
 | 5     46    1     | 49    2     8     | 69    7     3     |
 | 267   467   267   | 5     3     49    | 69    8     1     |
 | 3     9     8     | 7     6     1     | 4     2     5     |
 *-----------------------------------------------------------*

I hate to look for chains, but that may be next.

Ted

EDIT ADDED: I just noted the post by Danny (dja95376 ) and realized we were at the same level except that he spotted that wonderful "useless" skyscraper on <9> to kill the beast. Great job Danny Exclamation
