Puzzle games on the app store tend to be packed with dozens of mindless filler levels that don’t get harder or introduce anything new, and only provide extra room for advertisements. This game is the best puzzle app I’ve ever played, and I couldn’t put it down until I had beaten it. It will make you think long and hard, often outside of the box (in many different senses), and you may have to learn something new to overcome certain levels. You have to pay incredibly close attention at times. Install this app if you enjoy logic and puzzles and are up for hunting inside and out for your solution. Even if you’re unsure, give it a try because it is free (and has no ads). This was an extremely satisfying adventure, and a huge breath of fresh air after wasting my time on so many other games. It restored my hope that exciting and engaging puzzles would not always be swamped by the quick and lazy money grabs that dominate the app store. 10/10

This was honestly one of the most interesting puzzle games for mobile I've played in a WHILE. Especially for free, no less—I'm a broke college student, so I can only rarely justify spending money on "frivolous" things like a game I might not enjoy, so I often don't get very far in apps. I occasionally had to put a puzzle down to think on it, but it was never out of frustration; it gnawed at my brain in just the right way!I will attempt to be as vague as possible to avoid spoiling the solution to a puzzle but, given I have to make the issue CLEAR, you have been warned!......I had to use up 3 hints on level 39 to skip—not because I didn't know exactly what it was looking for, but because modern iPhones don't have a home button anymore; I couldn't complete the level. I only have a high school half-year course worth of coding knowledge (and that's for stuff like BlueJ, not anything related to the intricacies of mobile app dev) but that could use some sort of update so people aren't confused, frustrated, and required to use hints when they don't ACTUALLY need to skip a level. (Otherwise, I loved this app!!)

This was really a great game. Had me thinking a whole lot. It’s not at all what I expected but it was amazing. I appreciate how easy it is to get hints with ads. (which I tried not to use TOO often!) Overall a really fun game and it really requires you to think outside the box. Just when you get used to coming up with crazy ideas to complete a level, it brings you to something so simple that you struggle with it because it’s very much inside the box. Every puzzle was very well made. Definitely an app that deserves more love!

I found the game really fun, interesting, and creative. I had a great time for most of my playthrough. However, level 40 did not function properly on my device, making it nearly impossible to complete. It kept going back to the scan without letting me do the rest of the level. By the time I had finally completed it, at least 15 minutes had passed. I can also see that other people online have access to the extra 10 levels, but I do not, which is a shame. I was a bit sad to find that such a unique game ended on a frustrating note. Aside from these points, I found the game very enjoyable.p, and hope to be able to play the remaining 10 levels some day.
