Nonogram
Fill in the grid using the number clues to reveal a picture
About Nonogram
Nonogram, also called Picross or Griddlers, is a logic puzzle where number clues reveal a hidden pixel picture. The clues along each row and column tell you how many consecutive filled cells appear in that line. Deduce from the clues which cells must be filled and which must be empty until the complete image emerges. Nonograms are popular in Japan, Europe, and among puzzle enthusiasts worldwide because they combine rigorous logical deduction with the satisfying reveal of a hidden image. Flario's Nonogram offers puzzles from 5×5 to 15×15 grids.

Frequently Asked Questions
How do the number clues work in Nonogram?
Each number in a row or column clue represents a consecutive run of filled cells. A clue of '3 2' means there is a run of 3 filled cells followed by at least one empty cell followed by a run of 2 filled cells, in that order from left to right or top to bottom.
How do I mark empty cells in Nonogram?
On desktop, right-click a cell to mark it as empty (usually shown as an X or dot). On mobile, tap a filled cell again or use the mode toggle button. Marking empty cells is as important as filling cells — it helps you track confirmed safe spaces.
Do I need to guess in Nonogram?
Well-designed Nonogram puzzles can always be solved by pure logic without guessing. If you find yourself needing to guess, it usually means there is a logical deduction you have not yet spotted. Look for rows or columns where the clue numbers leave very few possible arrangements.
What is the best way to start a Nonogram puzzle?
Start with rows and columns where the clue numbers are large relative to the grid size — these have the fewest possible arrangements. For example, a clue of '8' in a 10-column grid means the filled run must cover at least cells 3–8 regardless of where it starts.
Is Nonogram good for the brain?
Yes. Nonograms develop logical deduction, pattern recognition, and systematic elimination — the same skills used in mathematics, programming, and scientific reasoning. They are often recommended by occupational therapists as cognitive maintenance exercises.
What size puzzles does Flario's Nonogram offer?
Flario's Nonogram starts with 5×5 grids for beginners and scales up to 15×15 grids for advanced players. Larger puzzles reveal more complex pixel images and require sustained logical focus over longer sessions.
