How to play

A nonogram is a picture solved from row and column clues.

The numbers beside each row and above each column tell you the runs of filled squares. For example, a clue of 2 1 means two filled squares, at least one empty square, then one filled square.

Coach moment

Start with the 4-clue rows, mark obvious empty cells, and use Undo when experimenting. The app teaches the next safe move instead of forcing a timer.

1. Start with certain lines

Long clues on short rows create overlap. If every possible placement fills the same cell, that cell is safe to fill.

2. Mark confirmed empty cells

When a run is complete, mark the bordering cells as empty. Empty marks reduce guessing and make the next clue easier.

3. Switch between rows and columns

A row decision changes the column clues, and a column decision changes the row clues. Calm solving is a loop, not a race.

4. Use hints as teaching, not answers

Calm Nonogram Coach points to a logical next move so beginners can build pattern recognition instead of simply revealing the picture.

Quick rule of thumb

Never guess if you can prove a filled or empty cell from the clues. If you feel stuck, look for a completed run, a row with a large clue, or a column where existing filled cells force the next square.
