In the last cell, 2 can ONLY be in the first column. I don't think the logic/possible calculates this. (Test Time!)
Ok, if there's a board like this (one column shown):
```
╔═══╦═══╦═══╗
║ 2 ║ ║ ║
║ ║ ║ ║
║ ║ ║ ║
╠═══╬═══╬═══╣
║3 ║ ║ ║
║4 ║ ║ ║
║5 ║ ║ ║
╠═══╬═══╬═══╣
║ ║ ║ ║
║ ║ ║ ║
║ ║ ║ ║
╚═══╩═══╩═══╝
