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.
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. Instead, you buy only the galleries you want at a fair, honest price. Own them forever, and share them with your family.
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.

Browsing now shows you every gallery, not just the ones you own, listed right under "More Galleries" so you can jump straight to any of them in the Gift Shop.
Finish every puzzle in the free Starter gallery and a card points you to what's next.
Also in this update:
- The Gift Shop opens straight to its prices instead of starting collapsed, every item has a clear Buy button, and the Gift Shop is reachable from anywhere you're browsing, including on iPhone.
- If a purchase needs approval (like Ask to Buy), the Gift Shop now says so instead of looking like nothing happened.
- Fixed a rare case where the all-access Museum Membership pass could briefly show only the Starter gallery right after launch.
