Nonogram run constraints
Ordered row and column clues describe filled runs separated by gaps. Intersections determine forced filled and empty cells.
The player's decision
Use overlap in a long run or split a row around known empty cells?
Original scenario
Original setup: a run of three in five cells forces the middle cell; use its column to continue.
Start with this prototype
Build three original 5×5 patterns with filled, empty and undecided states plus undo. Hints explain one deduction. Verify uniqueness and a no-guess solving path before release.
Change one variable
Reduce starting deductions and check that each stage retains an explainable inference.
What to observe in a playtest
Does run counting include the final run? Do different deduction orders reach the same solution?
Take the full design card

Original analysis · version 1
Common pitfall
Treating undecided as empty causes premature completion or misleading errors; keep three states distinct.
Observations and sources
Cases refer to public documentation. Developers and community wikis are credited separately; document review is not a claim of hands-on testing.
