The game will introduce you to chemical symbols in a casual manner; they will replace numbers. Your task is to shoot accurately at a rotating target, inside of which chemical elements from the periodic table appear. The number of shots determines the location of each element. You must hit the target, but the next shot must never hit the same place, otherwise all your points will be lost. For each shot you will receive one point. When the circle dissolves, you will complete the level in Aimistry.
