In the "Logic Lines" game on BlackBerry (also sometimes called "Color Lines" or "Win Lines"), the goal is to clear the playing field by creating horizontal, vertical, or diagonal lines of five or more colored balls of the same color, removing them from the board and allowing new balls to fall down to fill the gaps; the game ends when the board becomes fully filled with no possible moves to create a line.

I implemented the game logic, draw custom components and added smooth animations. I supported different screen resolutions and stored user data.
