About this game

Nonograms Katana: Sharpen your mind!

Nonograms, also known as Hanjie, Griddlers, Picross, Japanese Crosswords, Japanese Puzzles, Pic-a-Pix, "Paint by numbers" and other names, are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden picture. The numbers are a form of discrete tomography that measures how many unbroken lines of filled-in squares there are in any given row or column. For example, a clue of "4 8 3" would mean there are sets of four, eight, and three filled squares, in that order, with at least one blank square between successive groups.
To solve a puzzle, one needs to determine which cells will be boxes and which will be empty. Determining which cells are to be left empty (called spaces) is as important as determining which to fill (called boxes). Later in the solving process, the spaces help determine where a clue (continuing block of boxes and a number in the legend) may spread. Solvers usually use a dot or a cross to mark cells they are certain are spaces.
It is also important never to guess. Only cells that can be determined by logic should be filled. If guessing, a single error can spread over the entire field and completely ruin the solution.

Ratings and reviews

hours of fun and entertainment. please keep this updated to work forever. I've had this all installed for years and my only complaint is the difficulty workout on larger puzzles. Anything above 20x20 starts to get very tedious and eye squinting for me. Or gives me headaches from all the planning and zooming. I would love to see the web version include the Guild feature, or have some kind of Chromecast option to enhance the experiences on larger puzzles.

The best,it still great.Is free with ads, the ads are small, and doesn't impact the usage of the app.This developer deserves the support,paid $2 for the VIP,no ads,and extra features, but I got it to support a great job.This is the most complete feature rich Nonogram app, tested several,and this app has several features not available on other app. The opt to creat you own puzzles, the option to print or save to PDF format, save locally, save online to offline to play without using internet❤️😁👍

Really nice version of nanograms. But there does not seem to be a way to restore purchases of VIP across devices. I got VIP last night on my phone. Then decided it would be nice to play on my tablet with a stylus. Even though I can sync my saves and progress, it does not seem to carry over the VIP purchase so if I play on my tablet, I still get pop up ads. Unless there is a way I am unaware of, I find this to be a big downer. Otherwise, it would have been a 4/5.
