As the player progresses through patterns, new elements are added to the gameplay. After the fourth stage, if the ball comes into contact with the top of the area, the paddle's size is halved until the stage is cleared or a life is lost. From this point on, the third stage variant features hidden bricks above the ceiling that descend progressively, using a similar—or same—layout that must also be cleared, meaning the pattern must be cleared twice. In later levels, bricks in the second stage variant may not move at the same speed or in the same direction. After the twelfth stage, indestructible bricks are incorporated into the brick patterns.
