❓ Frequently Asked Questions
▶How do nonogram clues work?
Each number in a clue shows the length of a consecutive block of filled cells in that row or column. Multiple numbers mean multiple separate blocks, in that order, with at least one empty cell between them.
▶What does MARK mode do in Nonogram Grid?
MARK mode lets you place an X on cells you are certain should be empty. This helps you visualize constraints and avoid accidentally filling the wrong cells. Marks never count as mistakes.
▶How is scoring calculated in Nonogram Grid?
Your score is based on a difficulty multiplier, a time bonus for fast completions, and deductions for mistakes and hints used. Complete harder puzzles quickly with zero hints for the highest scores.
