❓ 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.
How many mistakes can I make in Nonogram Grid?
Five. Filling a cell that should be empty counts as a mistake; MARK Xs never do. At 5 mistakes the puzzle ends. Hints reveal one correct filled cell and cost 50 points if you used any — save them for genuine deadlocks.
What grid sizes are the Easy, Medium and Hard puzzles?
Easy puzzles are 5×5, Medium 10×10, and Hard 15×10. Each difficulty has a small set of named pictures (Square, Heart, Star…). The score multiplies ×1 / ×2 / ×3 by difficulty, so a clean Hard solve is worth far more than a slow Easy one.
What is the exact Nonogram Grid score formula?
(200 + time bonus − mistakes×20 − hint 50 if used) × difficulty (1/2/3), floor 100. Time bonus is max(0, 300 − seconds). 5 wrong fills end the puzzle. MARK Xs never count as mistakes.
Can two people play, and how many hints do I get?
Solo only. HINT fills one unfilled correct cell; you can tap it more than once, but the −50 penalty is a single flag. Easy 5×5, Medium 10×10, Hard 15×10. Free in the browser, tap cells, no download.
Can I erase a filled cell, and how are Nonogram Grid puzzles chosen?
Yes — in FILL mode, tap a filled cell to empty it again (a wrong fill already counted still stays on the mistake HUD). MARK Xs never count as mistakes. Each Easy/Medium/Hard start picks one of five named pictures at random: Easy Square/Heart/Star/Circle/S-Shape, Medium Diamond/Arrow/Hourglass/Oval/X-Mark, Hard Triangle/Maze/Rocket/Lightning/Grid. Solo, free in the browser, no download.
Can a wrong fill block my win in Nonogram Grid?
Yes. The win check requires every solution cell filled and zero wrong fills on the board — a wrong fill stays put and blocks the win until you erase it by tapping it again in FILL mode. Erasing clears the cell, but the mistake still counts on the 5-mistake HUD, and each mistake costs 20 points in the final formula.
