Nonogram Intersections
📋 What it is
Where a row clue and a column clue both force the same square, that square is settled for sure.
🗣️ Coach says
The magic of nonograms is intersections. If a row says a square is filled AND its column agrees, it’s locked. Play row-clues and column-clues against each other.
🧠 Memory hook
Row says yes + column says yes = LOCKED. Two agreements beat one guess.
😂 Giggle
Why did the clever first guess matter so much?
Because a good opening gives you the most information!
😲 Whoa!
Hard nonograms are solved almost entirely by intersections — never by guessing. If you’re guessing, there’s usually an intersection you missed.
✅ Quick check: Your row-logic says a square is filled, but your column-logic says it must be empty. What went wrong?
Say your answer out loud first — then reveal.
You made an error earlier — a true nonogram never contradicts itself, so go back and recheck a run.
A contradiction is a signal to re-examine, not to guess — the puzzle is always consistent.
