Make sure to tell it NOT to automatically check your work, since mis-taps definitely happen on a phone-sized UI. The problem with this app is there aren't enough puzzles. I paid for the "daily" package (and none of the other ones) but didn't realize this means it randomly selects puzzles from everything that's already available in all the other puzzle packs, i.e. *not* 5-10 new puzzles every day. When the Daily puzzles load, half of them will load as already solved since you already solved them in the Free collections. Then, some of the ones that appear to be unsolved turn out to be repeats of ones you solved in other Daily puzzle sets, since it will only remember a puzzle as solved if you paid for its individual collection. (Oh look...the Globe puzzle again. How quaint.) It's a shame, since I really like this UI. More puzzles please! ## Most critical reviews (10 lowest-rated) ### 1/5 — Why ask review? *2017-03-04* Not good ### 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. ### 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. ### 1/5 — No longer works *2015-06-20* Loved this game and had bought puzzle sets but now it doesn't work, have tried everything! Please help! Or give me back my money. ### 1/5 — Unable to open *2015-02-28* I have used this app for a long time and have bought many in app purchases but after this update I am unable to open it! I have a first generation IPad. Please fix this quickly to support a loyal customer before I lose interest and uninstall the app. I deleted the app and reinstalled it in case this was the problem as well as shutting my IPad off and restarting. I have noticed other complaints of with the same problem so it is not an isolated case. Ok. It's been a week since I posted this and over two weeks since some of the other crashing reviews without a reply from picross. There needs to be some kind of response or you are going to lose my business. ### 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. ### 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. ### 2/5 — Very annoying interface *2012-06-27* This game could be lots of fun, but the interface ruins it for me. Having to press a button each time you want to alternate between xed and black markings is a massive hassle and the buttons are far too small. Probably 20-50 times a game, I miss the small button and color the square the wrong color. I would like it much better if you could click on a square once to change it black, once more to x it out, and again to clear the square. Or at least move the buttons, or make them bigger. My arm should not get tired when playing a puzzle game on my iPad. Also, the numbers are too difficult to determine if they have been greyed out or not. Especially when they are 2 similar shades of grey on 2 other shade of grey background. This could easily be solved by making greyed out numbers turn blue, or red, or literally any color besides "slightly less grey" I would also prefer there to be an option to disable the timer. ### 3/5 — Good nonograms, horrible execution *2016-01-31* Navigational layout of app needs improvement. Actual gameplay is fine. ### 3/5 — Fix this please! *2015-02-13* Your latest update causes the app to crash right after I tap it. I love playing this game so please fix it! ## Most praised reviews (9 highest-rated) ### 5/5 — Addictive game! *2017-02-27* I would like the fill button and X button to be a little larger and spaced apart more. I use my thumb and no I hit one button only to find it didn't switch. ### 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! ### 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! ### 5/5 — Love it *2015-06-21* I love it. Hours of fun. ### 5/5 — Love this game!!! *2015-05-11* I am OBSESSED with this game! I have never had any problems with it after uploads... The only problem is that I wish they would create new puzzles faster! I have reset and replayed all the puzzles at least 3-4 times!! Best picross game available!! ### 5/5 — Great Puzzle Game! *2015-04-09* I love this title! ### 5/5 — YES *2015-02-17* I've tried many a Picross, but this one definitely has the smoothest controls and many fun puzzles! ### 5/5 — ALMOST Perfect *2011-08-21* The ONLY flaw I found in this otherwise perfect interface is that sometimes when I thought I had switched from "x" to "fill solid" mode, I wouldn't realize that it didn't register my touching the button (I believe it doesn't always register because it is so close to the edge of the screen). This would result in me puttting the wrong mark and getting a penalty (if using the hints mode). If they would add an option for a sound effect (and a vibration even) letting you know it registered your selection they would have the perfect interface (or at least move the marker selection button a few pixels away from the edge of the screen). The only other issue I have is with the jumps in difficulty of the puzzles. If it had a difficulty rating of each puzzle (or even better a way to sort the puzzles by difficulty) it would prevent frustration. These are actually minor flaws, but prevent it from getting a perfect 5/5 rating. That said, I love this game and have a very hard time putting it down.
