Balls Love Puzzles comes from QinYuan Tian. Balls bounce around the grid and the object is to rearrange the squares in order to restore order.

JiggleSaw came out 6 years ago and is very similar. It has more features and is a fun little gem. Unfortunately, it is no longer available.
Balls Love Puzzles has 48 levels and is fun. I solved them all.  The most I spent on any 1 level was about 7 minutes. On some levels the balls move pretty fast.
