Objective: All you must do, in this online physics puzzle game, is keep the smiling little green ball from falling off the screen. To do this, construct something from the available materials and then let the little ball drop. You have a budget, and each of the available building materials (blocks, plates, and iron bars to hold them all together) has a particular cost. So build wisely.
