Imagine that on top of your game field falling balls are very good jump, and your job is to keep them as long as possible on their playing field, do not let them depart from there. To do this, you have a few stone blocks, which you must place in this order to balls constantly fought back from them, and could not fly beyond your playing field. You can only rearrange the cubes before the departure of the ball, so look at the trajectory of a ball and pick up the correct alignment of blocks.
