And now for something completely different:
Code:
+----------------+----------------+----------------+
| 3    9    1    | 5    7    4    | 2    8    6    |
| 2    8    4    | 3    9    6    | 1    5    7    |
| 7    6    5    | 1    28   28   |-39   4    39   |
+----------------+----------------+----------------+
| 4    1    78   | 2    58   3    |69+57 67   59   |
| 6    3    78   | 9    4    58   | 57   12   12   |
| 5    2    9    | 6    1    7    | 4    3    8    |
+----------------+----------------+----------------+
| 9    7    26   | 8    35   1    | 35   26   4    |
| 8    5    26   | 4    23   9    |67+3 17+26 13+2 |
| 1    4    3    | 7    6    25   | 8    9    25   |
+----------------+----------------+----------------+

BUG+4

The grid shows the Deadly Pattern and the candidates that destroy the DP. For example, in R4C7 69 is the DP, 57 destroys the DP.

For each of the + candidates that destroy the DP, the common outcome is R3C7=9.
