Nonogram Logic Puzzles Reveal hidden pictures one deduction at a time. LogiSketch is a beautifully crafted nonogram app (aka Picross, Griddlers, Hanjie, and Paint by Numbers) built for players who love pure logic, from your very first puzzle to brain-bending marathons. START FREE The Starter gallery is free the moment you install. When you want more, buy just the galleries you like, from $0.99 each, or unlock them all with the Museum Membership. No subscriptions: own what you buy, forever. MASSIVE LIBRARY, FROM TINY TO GIGANTIC Start with quick, bite-sized grids and work your way up to sprawling, gigantic puzzles that unfold like real artwork. With thousands of hand-curated puzzles across dozens of themed galleries, you will never run out of challenges. Whether you have two minutes or two hours, there is always a perfect puzzle waiting. 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. PLAY ANYWHERE, NO WIFI REQUIRED Because there are no ads to load, LogiSketch works completely offline. Solve on a plane, on the subway, in the mountains, or anywhere with no signal. 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. WHY PLAYERS LOVE LOGISKETCH • Free to start: the whole Starter gallery, no purchase required. • Thousands of professionally designed puzzles, from tiny to gigantic. • Honest, genuine difficulty ratings based on solving methodology, not just grid size. • No ads and no internet required. • Buy only the galleries you want, from $0.99, and keep them forever. • Clean, elegant design that looks stunning in light and dark mode. • Your puzzle progress follows your iCloud account: iPhone, iPad, and Mac.

KernelLogic is a nonogram (picross) puzzle game wrapped in a cyberpunk shell. Every puzzle you solve decrypts a sector of a corrupted neural network, revealing the pixel art hidden inside a grid of clues. FEATURES - Classic nonogram/picross logic: use row and column clues to fill in the correct cells - Glitch cells that flicker and demand a fast, confident tap - Encrypted cells that need to be tapped twice to breach - Firewall cells that only unlock once their row or column is fully solved - Focus Isolation Mode: long-press a clue to isolate a single row or column when a puzzle gets dense - Dozens of hand-crafted levels across multiple zones, with new sectors added regularly - Clean, minimal cyberpunk UI with neon glow, glitch scanlines, and satisfying haptics and sound No ads interrupting your puzzles. Solve at your own pace: KernelLogic tracks your progress locally on your device. Unlock the full game once to access every zone and level, forever.
