Keys & Controls
Nonogram Rules
Each number in a clue represents a group of consecutive filled cells. Groups are separated by at least one empty cell.
Clue numbers are read left-to-right (for rows) and top-to-bottom (for columns). The order is guaranteed.
Marking known empty cells with X helps narrow down where filled cells can go. Use it liberally.
Use both row AND column clues together. A cell filled by one deduction confirms or eliminates options in the crossing line.
How to Read a Clue
A row clue of "3 2" means: one group of 3 filled cells, then at least 1 empty cell, then a group of 2 filled cells.
Strategies for Solving
Start with the longest groups — they have the least flexibility and give the most information.
If a clue number equals the line length, the entire line is filled. Easy win!
"Overlap technique": if a group could span positions 1–5 OR 3–7, positions 3–5 must be filled regardless.
Work on the most constrained lines first — lines with large numbers relative to the grid size.
When a line is nearly full, use elimination to place the remaining cells precisely.
