Pixel Logic

📖 Read the strategy guide ›

Pixel Logic is a picture logic puzzle, sometimes called a nonogram. The numbers beside each row and column tell you how many cells in a row are filled in that line. Use logic to fill the right cells, mark the empty ones, and reveal the hidden picture.

How to play

  1. Choose a size: 5×5, 10×10 or 15×15.
  2. Read the numbers beside each row and column: they show the runs of filled cells in that line.
  3. Fill the cells you are sure about.
  4. Mark cells you know are empty with an X.
  5. Wrong fills cost a life; complete the grid to reveal the picture.

Controls

Computer
Click to fill cells and switch to Mark mode for X's. Arrow keys move, Enter or F fills, X marks, M switches mode and H gives a hint.
Phone and tablet
Tap or drag to fill cells. Switch to Mark mode to place X's.

Tips

  • Start with lines whose numbers almost fill the whole row.
  • Marking empty cells helps you see what is left.
  • Work back and forth between rows and columns.

Questions

What do the numbers mean?
Each number is a run of filled cells in that row or column, in order, with at least one empty cell between runs.
What happens if I fill a wrong cell?
You lose a life. Run out of lives and the puzzle ends.
