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.

Favorite game!

*UPDATE 5/26*
As of tonight everything seems to be working again. This is my favorite game. I lay in bed and play it for hours pretty much every night while I try to wind down to go to sleep. I love that users can submit new puzzles as those are the most fun. Highly recommend it!

*initial review*
It seems they may have stopped supporting this app as the servers seem to be down and the website for the developer also throws a ‘server not responding’ error. I hope this is wrong as I would love to come back and update my review. This was my favorite app prior to the issues.

One of my favorite game, but the newest version has a bug

I love nonograms and this has the best interface I've ever used. And the free user generated content is awesome. However I would like to point out that, when I sort by author, it doesn't order by author alphabet any more; in fact by author and by date produce the same order. This is only happening in the newest update and I think it's a bug. Please fix the bug, thanks a lot!

Love it BUT

I love this app I’ve had it for over a year, but it’s not working lately. I haven’t been able to open any new puzzles in a few days. Deleted and re-downloaded and it’s still not downloading the information, so now I have zero puzzles available because it’s not connecting. I’ve never had this issue before. Tried at work and home, wifi and data. Nothing is working.
