## Nonograms Katana Description
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.

## Nonograms Katana Reviews in United States

### ***** "Best Nonagram App Ever"
I do use the features that make it easier, but honestly, it’s given me endless hours of fun and relaxation. This is the game I go to when I need to wind down before bed, when I don’t have wifi, when I’m waiting in line, whenever. The user-made nonagrams are the greatest, and getting to work on 80x80 grids of my favorite characters is a wonderful challenge. The ads are never more than 5 seconds, but I finally bought the VIP package (for only $2.99!) because I wanted to support the devs. You won’t regret getting this. Thank you devs!

### ***-- "Better on Android"
I love this app, but I prefer it on my android. I love having quests and things to work toward rather than just the puzzles and the adventure and story is cute and fun. I find that I miss that in this version, but the puzzles are great
-- TeaQueen21, 2024-12-20

### ***** "Years later still my favorite game"
I play this daily.   Looking at switching from iOS to android- what the FIRST thing I wonder —- how do I keep this app??    Ty so very much.
-- lakeout, 2024-12-12

### *---- "App broken today"
I tap on a box and all boxes are filled with that color. What???
-- Lambweaves, 2024-12-05

### ***** "Look no further"
This app is a masterpiece for nonograms
-- Gianni.Atwood, 2024-11-21

### *---- "No guilds/Quests! (Should be 5 star)"
Please give us all our progress back in guilds and quests!
-- VandalBarber, 2024-11-04

### ***** "Challenging and fun"
The game is fun because it shows you when you made a mistake so you can fix it without frustration.  There is only one ad when you start.  I like all the hints available too.
-- Chentsuire1234, 2024-08-09

### *---- "disturbing"
had a sw*stika as one of the first puzzles?? I feel like that is something that is way too easy to recognize and avoid for it to make it to the final product. Never written a review on here before but personally I think it’s just too disturbing to not warn people about.
-- egibm, 2024-07-31

### *---- "iOS 17"
Today I downloaded new update for my iPad and after 6 years of using this the best app, it can’t start and shut down every time
-- Cuuuuuuuba, 2024-07-19

### ***** "Challenge your reasoning mind"
This game stimulates and challenges your logic reasoning mind.  There is no background computer interference. 
Enjoyable, challenging and stimulating. What more could you ask for my fellow seniors?
