The game starts with a grid with different colored balls on some of the squares. The four sides of the grid is surrounded by more colored balls. You tap one of the colored balls that is surrounding the grid and it moves either vertically or horizontally depending on if the ball is on one of the sides, the top or the bottom. When the ball runs into one of the balls in the grid and is the same color the balls dissappear. If they are different colors, the ball is added to the grid. Either way the ball you tapped is replaced with another ball.

I've seen this game on a PDA and on a cell phone but I don't know the name of it. I know it came on the PDA but I don't know if it came on the phone or if it was downloaded. Any help would be appreciated. Thanks.

It's not Jawbreaker because that doesn't have a few balls on the grid surrounded by a row on the top, bottom and 2 sides.
