The only nonogram I really like

Even though it is a bit challenging, I have been playing this for awhile and I love solving the images its also very “rogue” it will give you a tutorial but then you’re on your own having to learn more tricks and tips just from experience which I personally dont mind. This is one of my favorite things to do on my free time and all puzzles are do never get tiring and I can always challenge myself. Though the only annoying thing is when you’re pressing a new puzzle like 95% theres an ad but its only 2.99. The biggest thing that it isnt like other games and let you explore and go at your own pace like if you’re intermediate and looking for new puzzles you can jump straight to like 20x20. Overall great app I love the controls and interface. Everything is so helpful and you adjust it to your personal preference with or without assistance. Being able to customize the way you use tools and stuff! 10/10 Recommend.

Wow...

I’ve just now started to really get into doing nonograms bc this app was the best I’ve had for these puzzles, and I got up the courage to do some of my own and I absolutely loved the puzzles that I made bc they were overall cool to look at...but I made the mistake of thinking other people would think they were cool and published them... the result was comments on how they were boring to do and insulting my picture and making me feel like crap for even expressing my style... apart from already having three of my favorite puzzles completely deleted by the system bc there was other puzzles in the same category? I thought that’s what categories were for? (Did you know that?)...and so now they’re gone for good, not even there for me to see and keep. I am not happy with this disrespect and censorship. Seriously this app is a contradiction, you simply aren’t allowed make puzzles that other people don't find worth their time, but do it to begin with only to be snobbish towards you. I’m only keeping this app bc of my puzzles that got accepted and the fact that I enjoy and appreciate the puzzles that people took their time to share with others their style. P.S. Don’t be miserable and make others feel bad for it.

Best nonogram by far

I did rare this 5 stars but I would like to see a change. Currently if you make a mistake you can’t tell it’s a mistake until it contradicts something else. And you can go back but you don’t know how far is necessary. You CAN check for ‘correctness’ but the way it does, I couldn’t figure out if it was right or not. It was corrected but I couldn’t tell what it affected. I’d like to see just a highlight of what is wrong and I’d like to correct it so I know what it affects. Also a clue to how many mistakes would be nice. I don’t want to keep playing if there are mistakes. If there was a counter for number of mistakes and I could just go back till it was zero and figure it out myself, that would be ideal :) I’ve tried many nonogram apps and this one is my favorite by far. There are others with adventure style play but this one is just simple and I like that.
