Nonogram Square for iPhone

Game overview and concept

Nonogram Square is a logic-based puzzle that uncovers a hidden picture by filling or leaving cells blank according to numeric hints. Also known as Nonograms or Paint-by-Numbers, the game asks you to translate number sequences into runs of filled squares to gradually reveal pixel-style artwork. The challenge blends deduction and pattern recognition for a satisfying visual payoff.

Gameplay basics

• Read the numbers beside each row and column to know how many consecutive cells belong to a block.
• Mark cells that must be filled and mark definite blanks as you deduce them, using spacing rules to separate blocks.
• Continue solving row-by-row and column-by-column until the entire image is resolved.

Grid sizes and difficulty options

• 25 x 25 — for the most complex, time-consuming puzzles
• 20 x 20 — challenging, with larger patterns
• 15 x 15 — medium-to-hard puzzles that require solid deduction
• 10 x 10 — intermediate level for steady progress
• 5 x 5 — quick, beginner-friendly grids

These size options provide a range of difficulty so players can pick puzzles that suit their experience and available time.

How to read the clues

Numbers given for each line represent consecutive filled segments. For example, a clue shown as "4 8 3" indicates a block of four filled squares, then at least one empty square, a block of eight, another gap, and then a block of three. Use overlaps, edge rules, and cross-checking with intersecting lines to place guaranteed fills and blanks.
