Your goal in this puzzle game is to destroy balls by connecting 4 or more balls of the same color. You can rotate or move them before dropping them to the group to pile them up. Use the LEFT and RIGHT ARROW KEYS to move, and UP and DOWN ARROW KEYS to rotate. Press SPACEBAR to drop falling balls. When the balls become unstable, they will roll down, making the positions of the balls difficult to predict and the game is more challenging. Good luck!
