In this game there will be an area where you drop balls to pile them up. When the balls become unstable, they will roll down, making the positions of the balls difficult to predict and the game is more challenging. Use the left and right arrow keys to move the falling balls, use the up and down arrow keys to rotate them, and press the spacebar to drop the falling balls. Make sure to destroy the balls by connecting four or more balls of the same color! Be quick though, for the balls will keep piling and if it reaches the top you will lose!
