I don't trust myself anymore. Before posting my one-stepper I played it on Draw/Play, only to get different results, so it was back to P&P.

Code:

+-------+-------+-------+
| 1 7 8 | . . . | . . 6 |
| . . 2 | . 8 . | 3 . . |
| 3 . . | . 5 . | 1 . . |
+-------+-------+-------+
| 5 . 3 | 8 . . | . . . |
| . 8 . | . . . | . 5 . |
| . . . | . . 9 | 8 . 1 |
+-------+-------+-------+
| . . 4 | . 1 . | . . 9 |
| . . 6 | . 9 . | 4 . . |
| 9 . . | . . . | 7 1 8 |
