How to Play Nonogram
Nonogram (also known as Picross or Griddlers) is a classic logic puzzle: the numbers beside each row and above each column tell you the lengths of consecutive filled cells. A clue of "2 3" means the line contains a run of 2 filled cells and a run of 3, in that order, with at least one empty cell between them. Combine all the clues, fill exactly the right cells, and a pixel picture emerges.
House rules: in Fill mode, clicking a wrong cell costs one of your 3 lives (the cell is auto-marked); Mark mode places ✕ on cells you're sure are empty, with no penalty. On desktop, right-click marks directly.
Solving Tips
- Start with full lines: clues that exactly fill the grid (like "8" or "4 4" in 10×10) have only one solution — fill them first.
- Push from both ends: place a run flush-left and flush-right; any overlap is guaranteed to be filled.
- Mark aggressively: ✕-marking confirmed empty cells removes noise and speeds up deduction.
- Cross-check: every cell you fill instantly becomes a clue for its column — alternate rows and columns for the fastest solve.
Painting by Numbers, Deduced
Nonograms were popularized in late-1980s Japan, credited to editor Non Ishida's picture-grid puzzles, and spread worldwide as Paint by Numbers, Griddlers and — through Nintendo's long-running series — Picross. The rules read like a logician's joke: a list of numbers per row and column, and nothing else. Each number is the length of a solid block of filled cells, and from those bare clues alone a complete picture emerges.
The joy is the moment of emergence. You grind away at crossing counts and edge constraints with no idea what the image is, and then some middle stretch clicks into place and suddenly there is a cat, a cup, a sailboat. Every puzzle in our collection is a designed picture with a single intended solution, solvable by deduction alone — no guessing required, only patience and the slow satisfaction of watching empty grid become drawing.
よくある質問
How do I play Nonogram?
Read the number clues for each row and column (lengths of consecutive filled cells), deduce which cells to fill, and complete the hidden picture. Wrong fills cost a life — three mistakes end the round.
How do I read the clues?
"2 3" means the line has a run of 2 filled cells and a run of 3, in that order, separated by at least one empty cell.
Which pictures are included?
Five 10×10 puzzles for now — heart, house, tree, cat and star — dealt at random. More pictures and sizes are coming.
What is marking for?
Marking places a ✕ on cells you know are empty, helping you eliminate possibilities. It's penalty-free and reversible.
Do I ever need to guess in Nonogram?
No — well-formed nonograms like ours are designed so that careful deduction always finds the next certain cell. If you are stuck, re-read the clue lines where two blocks nearly touch, or check columns against the rows you have already partly filled; the contradiction you are hunting is usually one crossing away.
What is the easiest clue to start with in Nonogram?
Look for rows or columns where the blocks and their mandatory gaps fill the entire line — for example an 8-clue in a 10-cell row, or 4 + 1 + 4 in a 10. Those lines are forced cell for cell, and every cell you confirm there immediately helps the perpendicular clues.
