The numbers give the runs. Deduce the picture.
Each number is a run of filled squares, in order. Tap to fill, tap again to mark.
How to get unstuck
- Start with the fullest lines. A run that only just fits leaves squares that must be filled no matter where it sits.
- Mark the blanks. Knowing where a run cannot go is worth as much as knowing where it can, and it stops you re-checking.
- Work the crossings. Every square you settle in a row constrains its column too — that is where the puzzle actually unlocks.
