Marty,

I had only one bivalue cell (59) after basics. I repeated basics and obtained the same results..............

Ted,

Thanks for keeping me honest. After a second try (this time online), this is where I get after basics:

Code:

+-----------+--------------+----------------+
| 7   28  9 | 46   46  1   | 5   28    3    |
| 6   4   5 | 8    39  23  | 1   279   279  |
| 28  1   3 | 59   7   25  | 6   4     289  |
+-----------+--------------+----------------+
| 459 6   7 | 1    8   345 | 239 259   259  |
| 459 359 1 | 7    2   345 | 389 5689  5689 |
| 25  235 8 | 359  359 6   | 7   1     4    |
+-----------+--------------+----------------+
| 3   578 2 | 56   1   9   | 4   5678  5678 |
| 1   579 6 | 245  45  8   | 29  3     2579 |
| 589 589 4 | 2356 356 7   | 289 25689 1    |
+-----------+--------------+----------------+
