The area at the top of the field is where they spawn from. Wherever you click, the balls will fall from there. The goal in Fill The Glass Puzzle is to fill the glass at the bottom with marbles to the top. There is a free field between the glass and the ball generation zone, which at each level will be filled with various obstacles in the form of inclined platforms and other devices. Choose your pressure zone to hit the maximum number of balls on target in Fill The Glass Puzzle based on what's in the way they fall.
