How to use this in play
5 digit sets sum to 14 across 4 cells. The run on its own is permissive; its constraints become useful when intersected with the perpendicular runs at each of its cells.
Forbidden digits: 9. None of this digit appears in any valid combination, so you can rule it out of the run's cells immediately.
