When playing Bricks Breaking, you will need to plan ahead to make sure you end up with the right colours next to each other as the bricks get less. In order for you to figure this out, you would need to play the game a few times to see how the top ones fall as the break the bottom ones.
The idea of Bricks Breaking is to break all of the bricks or get as close as possible to that. Everything in the game is controlled using only the mouse. You move your cursor to one of the bricks in a group of bricks you want to break and click on it with the left mouse button.
