Nonogram — also known as Picross or Griddlers — is the elegant logic puzzle where numbers become pictures. A 10×10 board hides a pixel image. Row and column clues tell you the lengths of consecutive filled blocks. Use pure deduction to decide which cells to fill and which to cross out.
Our generator creates a fresh random picture for every game and derives perfectly consistent clues, so every puzzle is guaranteed solvable and has a single intended image. Tap to fill, right-click or long-press to cross, drag to paint, and watch the picture emerge. Toggle between difficulties via density, get a hint that reveals a random row, and use the Check button to highlight mistakes without spoiling the solution.
No math, no guessing — just clean logic. Finish faster with fewer errors for a higher score and more Retro Coins. Your best time is saved per device. Whether you love quick 5-minute solves or deep 20-minute deductions, Nonogram is the perfect brain teaser with endless fresh boards.
How to play Nonogram
- Read the clues. Numbers at the top and left show lengths of consecutive filled blocks in that row/column, in order. e.g., 3 1 means a block of 3, then at least one empty, then a single.
- Fill or cross cells. Left-click/tap to fill (black), right-click/long-press to cross (X). Drag to paint multiple cells. Crossed cells are known empty.
- Use logic, not guessing. If a row clue is 5 on a 10-wide board, the middle cells must be filled. Cross out cells that cannot be filled.
- Reveal the picture. When every row and column matches its clues, the hidden pixel art appears and you win.
- Score higher. Finish faster with fewer checks and mistakes for a higher score and more Retro Coins. Best time is saved.
Frequently asked questions
How do you play Nonogram?
Fill cells so each row/column has consecutive blocks matching its clues in order, separated by at least one empty. Cross cells you know are empty.
What do the numbers mean?
They are block lengths. 2 3 means a block of 2 filled cells, then a gap, then a block of 3, in that order.
How do I mark empty cells?
Right-click or long-press a cell to place a cross (X). Crossed cells are treated as empty for win checking.
Is every puzzle solvable?
Yes — each board is generated from a hidden picture and its clues are derived directly, so the intended image is always the unique solution.
How is the score calculated?
Base 10,000 minus time (seconds×2) and checks (×50), plus a 500-point clean bonus if you never use Check. Best score is saved.
