Japanese crosswords, also known as nonogram, hanjie, griddlers, picross, crucipixel, edel, figurepic, grafilogika, japanilaiset, karala!, kare, logicolor, logigraphe, oekaki, oekaki-mate, pic-a-pix, pikurosu, ristikot, shchor, square, tsunami, uftor or paint by numbers puzzles, started appearing in Japanese puzzle magazines. Non Ishida published three picture grid puzzles in 1988 in Japan under the name of "Window Art Puzzles". Subsequently in 1990, James Dalgety in the UK invented the name Nonograms after Non Ishida, and The Sunday Telegraph started publishing them on a weekly basis.

In japanese nonograms 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 Japanese nonogram, one needs to determine which squares will be filled and which will be empty.
These nonograms are often black and white, describing a binary image, but they can also be colored. If colored, the number clues are also colored to indicate the color of the squares. In such crossword two differently colored numbers may have a space in between them. For example, a black four followed by a red two could mean four black boxes, some empty spaces, and two red boxes, or it could simply mean four black boxes followed immediately by two red ones.
Hanjie has no theoretical limit on size, and is not restricted to square layouts.

Griddlers were implemented by 1995 on hand held electronic toys in Japan. They were released with name Picross - Picture Crossword.

Tricked me

Waiting for better...

I got the free version. I enjoyed the beginning puzzles and got through them in about an hour. For the first set, a 30-sec ad plays in order to unlock each puzzle. This is a quality app and the ads are shown at convenient times, so fine. After the ad for the first puzzle of the next set, there are three more ads (each 30 secs), which play immediately after the first and within three or four seconds of each other. During those seconds, the puzzle is available so the player has time to tap a few squares before the next ad appears. It feels like a glitch because three times the same ad interrupts what had previously been gameplay. I closed the app, restarted it, and was allowed to complete the puzzle (which took about a minute for those doing the math). Went to the next puzzle: four more ads in this manner.

Good first impression with the opening levels, but the sponsor delivery becomes disproportionate/obnoxious once you get into it a little more. You are asked to rate the app before this happens.

Thank you for reading!

Why no updates for so long?


This game was worth the money for the large, growing collection of puzzles. But there hasn't been an update since May. Why no new puzzles?
The interface for this game is the best of all similar nonogram puzzle games.
I wish that the randomly generated puzzles had large puzzles that also can have long rows and columns with solid color. The randomness setting tends to generate puzzles, even when very large, with 1's, 2’s,3’s,up to maybe 5’s, but not anything more than half of a long edge. I never see a 30x30 random puzzle with 18’s or 25’s, etc... they are solvable, but tedious. Almost all the random puzzles have about half the grid black, half clear, with lots of short segments. Some of them should have much more black, similar in density to the picture puzzles, but still random. Heck, just take some picture puzzles and randomly blend them.



Every time I think I'm about to run out of puzzles, they add new ones. I read a review about how easy the puzzles are and how they don't look like much- the person who wrote that must not have done many of the puzzles. Some of them are easy, especially when you are learning.. Then they get harder and harder, and better and better. Not to mention bigger and bigger. There's 8 levels right now each with 200+ puzzles plus a random generator that never runs out. You can skip levels too. I've honestly been playing this app for years and will continue as long as they keep adding new puzzles every now and then.
