I use my thumb and no I hit one button only to find it didn't switch. ### 2/5 — Umm no actual gameplay *2017-02-07* There is what I think is a glitch where you tap each individual square and it will automatically place an x or a square. So all you have to do is tap each square and you will eventually get the answer from that. It always places an x on an unused square and it puts a square on any square that is needed for the puzzle. So there is basically no gameplay. ### 1/5 — Loved it until loud blaring commercials *2016-08-14* I loved this game for a long time and purchased extra puzzles until just recently it started blaring loud video commercials upon launch. So annoying and no way to stop them. You can't even buy your way out. I'm going to switch to another app. My peace and quiet is worth more than that. So sad they ruined a good game. ### 2/5 — Developers are maybe a little lazy *2016-08-14* I bought the daily and daily big upgrades a long time ago. I can no recognize many of the puzzles, such as girl with hat and armadillo shopping just from the grid and numbers. This was a fun app for a while so no harm in downloading and playing, but I'd avoid the daily puzzle options if I knew then what I know now. ### 5/5 — Great game *2016-04-29* Tons of puzzles that start off easy and get more challenging. I love to spend time every day with this game- it's hard to stop playing! ### 3/5 — Good nonograms, horrible execution *2016-01-31* Navigational layout of app needs improvement. Actual gameplay is fine. ### 1/5 — Non functioning *2015-10-22* It's now approaching May. The app still isn't working. Ever since the update, it hasn't worked. Please repair this app... It's now approaching November. The app is still not working. ### 5/5 — Cute & fun logic puzzle game *2015-08-03* Great! Fun! Not a single problem. Thanks :) ### 5/5 — Fun times *2015-07-05* Enjoyed from the first tap. Been playing these types of puzzles for awhile now on paper. So happy to find one on line that I like. Easy to play! ## Frequently asked questions about Nanogram HD ### What is Nanogram HD?
