5 stars: I like that when an ad is triggered all u have to do is hit your back button and it brings u right back to your game no progress lost so u don't ever have to watch the ad the challenge was enjoyable but Ive finished the game u need more mazes
3 stars: I really like this game, but it consumes too much battery.
4 stars: Nice
4 stars: There used to be free hints after every 5th or 6th puzzle, after the last update this option isn't available anymore. Not cool.
4 stars: Good game.
4 stars: Notifications came in at 10:40am instead of 11:30pm! Thanks for getting that updated! This is a pretty fun game most puzzles are fairly easy but they scale quite nicely giving you a great challenge.
4 stars: Fun, simple, and addicting. Great for when you're sitting around waiting on appointments or otherwise only have a few minutes to kill. I'd give it five stars if there was a reasonably priced full version in order to stop the annoying pop-up ads every other level.
4 stars: I love the puzzles, fun to figure out. However, as others have noted, at some point the main menu starts popping up after every level, which is not a deal breaker but still annoying. Also, for some reason my zoom function isn't working on the larger puzzles. The notifications are annoying but easy to turn off. I must be a genius. EDIT: Looks like the main menu bug is fixed!
5 stars: I thought the game was great...Very addictive... Only wish there was more, finished all the puzzle...
