Nonogram: Picture Logic Puzzle

Nonograms are picture logic puzzles. Numbers beside each row and above each column tell you how many squares in that line are filled, and in what groups. Work out which squares to paint, and a hidden picture appears. FEATURES • 120+ puzzles across four board sizes: 5×5, 10×10, 15×15 and 20×20 • Every puzzle has a single solution that you can reach with logic alone • Each solved puzzle shows its picture in the level list, so you can build your collection • Mark squares you know are empty with an X • Lock painting or crossing so a slip of the finger doesn't ruin your progress • Undo your last moves • Finished lines are crossed out for you automatically (you can turn this off) • Play by touching the board, or with the on-screen direction pad • Four colour palettes, each in light and dark • Your best time is saved for every puzzle • Leave a puzzle at any time and continue right where you stopped • Sound and vibration can be turned on or off • No account needed, and puzzles work offline HOW TO PLAY A clue of "3 1" means that line has a run of 3 filled squares, then at least one gap, then a single filled square. Compare the rows and columns against each other to decide which squares must be filled and which must stay empty. This game shows a small banner ad. A one-time purchase removes it permanently.
