Pixel Logic

Pixel Logic is a classic Nonogram — also called Picross or Griddlers — a relaxing logic puzzle where the numbers are the clues. Use the counts along each row and column to work out which squares to fill, and a hidden pixel-art picture is revealed. Simple to learn, wonderfully addictive to master — free, offline and calm.
Work through themed picture packs, from quick 5×5 starters to detailed 15×15 scenes across Animals, Food, Symbols, Travel and Nature — or solve a fresh Daily Nonogram every day and build a streak on the calendar. Every hand-crafted puzzle has a single, logically-solvable answer, so it is always fair — no guessing. Fill and mark squares, let completed lines cross off automatically, and use the 'solve a line' hint when you are stuck. Collect every solved picture in your Gallery in colour, and track best times, no-mistake wins and streaks on the Stats screen.
