Both the lever in which the balls roll on and the lever controls exist; I'll refer to the former as "the lever" and the latter as the controls. The lever has to be balanced out evenly for the ball to not break. The two main controls on the platform are on the far left, which raises the platform, and far right, which creates the ball and "runs" the whole puzzle. The secondary controls move the fulcrum (the lever's pivot point) of the lever to either the left, center, or right positions, respectively from top to bottom.
