One of the many iPhone games that doesn't make good use of the accelerometer. The puzzles look interesting, but the ball doesn't move smoothly and tilting or swiping have very delayed effects. I am keeping it installed for now, hoping for an update to these interface problems, but I can't reccomend downloading it at this stage.

I also had the blank screen problem, which was repeatable, but I tried a Power Off and it opened up just fine after that. I haven't played with it much yet but find the action just a little sluggish -- it doesn't seem to move as smoothly as I expect, as someone else suggested -- so will give it 3 stars for now. Mostly just wanted to suggest the Power Off for anyone else encountering the blank screen thing.

This game is much fun exspexially since it's free I highly recomend it because it keeps you entertained for a long time. It might be a little hard but that's what makes the game more fun cause it's not like those dumb games u complete in like 5 minutes. I've completed every level 4 times so it is possible to beat:)

Well, for a free game this is very good! The graphics are pretty good. The only problem is that the ball doesn't move that smoothly, but since I have been playing it I have gotten better at using the accelerometer to play it. It is worth the download.
