The developer of Fayju Ball has set the game for Free for a day. We looked at the game back in June and found it to be a standout game in the Labyrinth/Ball Roller genre.
Like many other games in the App Store, Fayju Ball has you tilting your phone to try to get the ball(s) into the proper spots. This game, however, stands out in its use of puzzle elements as well as the 3D physics involved. Some levels require you to flip your iPhone upside down to get the balls to “fall" towards the screen.
Check this video to see it in action, or better yet, just download it for free.
