Nonograms KatanaNonograms 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 user reviews :

Probably the best nonogram app here I don’t think there is a better nonogram app on the Google Play Store. I love the auto cancel button and the interface works well on a Galaxy Note 5. Puzzles are pretty challenging too. Probably the best implementation of nonograms I’ve seen in a while since Picross on the Nintendo DS.

Best ever! I play a lot of these games in puzzle books(Variety, PennyPress, etc…) Was absolutely THRILLED when I discovered them on phone app!! Of all the nonogram games on my phone this one is the BEST. Never any list data, glitches, and rarely an ad now that I think about it. Well worth the download. As a matter-of-fact I would pay for this game! (and if ya knew me.. You would know how much weight that statement carried! Lol… Enjoy!

Challenging Great fun and challenging. I just don’t understand the scoring system.

  • Scoring system is not perfect, you get 1 point for every painted cell. But it’s not affecting anything, just achievements.
