This game is the best I have played this game more than any other on my phone and always enjoy the daily puzzles. Solutions can get surprisingly deep sometimes. This is also one of the rare cases where the game/app actually gets better when the dev updates it instead of just becoming a piece of slow, ad-ridden bloat. Looking forward to what the Incredible Company makes next.
A fascinating logic puzzle! A very simple premise and rule, but with some deep and elegant implications. It's much more than just a maze-running game; every possible choice along the path has one, and only one, correct answer, which can be logically deduced. A real thinker's puzzle!
Great app, some UI refinement would be nice. Swiping left and right in the main menu and within each book. Make daily puzzle available from any page. Prevent screen from turning off from lack of activity.
Cool game, a bit pricey 4 stars because you only get a few puzzles and can't open the advance puzzles, also a bit pricey, I pay a buck that's it. There will always be a corner in a corner unless its a entrance or exit, you'll find certain rules apply. Nice game, wish I could check out more before deciding to purchase.
Learn the rules! Stunningly good puzzle game. As I progressed more and more I kept learning new rules and invariants that any solution must satisfy. The learning curve is perfectly crafted so I was always able to make progress. Even up to five-star challenges I was still learning new things. If you like computer science or programming, this game is a must. Also if you like mazes. :-)
With two new books ("Practice Rooms" and "The Corners"), the game has more than 600 puzzles.
