NO ADS. EVER. We hate interruptions as much as you do. LogiSketch has zero ads: no banners, no pop-ups, no timers begging you to watch a video. Share your galleries with your family, too.

Your puzzles and progress are always right there, ready when you are. TRUE DIFFICULTY, RATED THE RIGHT WAY Most nonogram apps just call a big grid "hard." We do it properly. Every LogiSketch puzzle is analyzed by our solving engine and rated by the reasoning it actually requires: • Intuitive: learn the ropes with straightforward, satisfying deductions. • Logical: master the classic overlap technique and line-by-line reasoning. • Analytical: tackle puzzles that demand trial placements, contradiction arguments, and thinking several rows and columns ahead. A small grid can be fiendishly clever, and a big one can be a relaxing breeze. Now the rating finally tells you the truth. TOOLS FOR THE SERIOUS SOLVER LogiSketch respects expert players: • Q-marks let you record "maybe" hypotheses for advanced analytical reasoning, so you can explore possibilities without losing your place. • Extra gestures speed up filling, marking, and navigating: pinch or drag to select a region, row and column locking, and more. • Solve enormous puzzles your way: as one epic whole, or broken into manageable panels you complete one section at a time. Every control is designed to keep you in flow, not fighting the interface. COLOR AND BLACK & WHITE Enjoy timeless black-and-white logic puzzles, or dive into rich, full-color nonograms where each clue is tinted to its color. Color puzzles add a new dimension of strategy (including flexible spacing rules between colors) and reward you with vibrant pixel-art images. HINTS & TIPS WHEN YOU WANT THEM Stuck on a tricky line? A gentle hint will nudge you in the right direction without spoiling the fun, and helpful tips teach you the techniques the pros use. Prefer a challenge with stakes? Try Survivor mode, where careful play matters and every move counts. However you like to play, LogiSketch adapts to you.

Fill the squares, reveal the picture. Shadepix is a classic nonogram (picross) game with a calm dark board, one-finger drag painting, and pictures worth finishing. Every number tells you the length of a run of filled squares — read the clues, mark what must stay empty, and a hidden pixel picture appears. A DAILY PUZZLE FOR EVERYONE One puzzle a day, the same board for every player in the world, generated from the calendar date itself — no server required. The daily is how you earn diamonds: it pays more for every consecutive day, and every seventh day of a streak refills your energy for free. 330 HAND-DRAWN PICTURES Ten picture packs — Starter, Animals, Everyday Icons, Food, Space, Music, Vehicles, Sports, Nature and Weather — plus five advanced packs: Landmarks, Dinosaurs, Mythical Creatures, Deep Sea and Retro Tech, where one giant 20x20 picture is solved as four boards in a row. STAGES, ONE PICTURE AT A TIME Every pack is a 30-stage journey: clear a stage to open the next. Boards grow from quick 5x5 warm-ups to 15x15, and the advanced packs push to 20x20 — pinch to zoom on the big ones. MISTAKES CANNOT RUIN THE PICTURE A wrongly filled square is corrected to an × for you, so the picture never comes out wrong. But three mistakes end the board: continue for 60 diamonds, or start over for free. MEDALS AND LEADERBOARDS Bronze, silver and gold medals for pictures solved, packs completed, daily streaks and flawless clears — earned as Game Center achievements, with worldwide leaderboards for pictures solved and best streak. ENERGY INSTEAD OF ADS Starting a puzzle costs 1 energy from a bar of 5, and the bar refills on its own, one point every 15 minutes. The Daily never costs energy, and replaying a picture you have already solved is free. If you would rather not wait, a full refill costs 100 diamonds. BUILT TO BE PLEASANT - Drag across a row or column to fill several squares at once - Haptic feedback you can switch off - Works completely offline, on a plane or underground - Fully localized in 30 languages NO ADS. EVER. No banners, no interstitials, no rewarded video, no account, no tracking. Diamonds come from the daily puzzle, and optional diamond packs exist only if you want hints, unlocks or a refill sooner.
