Still one of my favorite apps ever. I know a lot of people being this up, but I would love a zoom feature. Also, I would like more options for the extra dimmer— like the ads could be dimmed as well so the brightness doesn't hurt my eyes in contrast to the rest of the screen. The hint system is also flawed. Ads don't always play when asked for a hint.

Thank you for your feedback. We apologize for the issue where hints were not provided even after watching ads, and we will forward the issue to our ad provider. We will also consider adding updates to improve the functionality.

One of my favorite nonogram apps. I would give it five stars, except for the hints. I get one about every 24 hours and when I try to watch an ad to get a free one, it never works. The ad won't play. When you are filling in grids with 900 boxes, the chances of getting one box wrong and setting off a chain reaction of errors is inevitable. I hate that I get one hint a day. That is a long time to wait. I usually am better off scrapping the entire puzzle and starting over which is tedious.

I love nonograms, I play them for hours a week, I've bought books in the past and have purchased both this and galaxy one. This game and galaxy one are almost perfect but have one major flaw, a lack of a zoom option. I can't play any puzzles larger than 20x20 because I can't see and accurately click them. I only get to experience a third of the game because of this and I can't be the only one.
