This online free game is designed to develop such qualities of yours as attentiveness and the ability to be persistent enough to reach goals. Attentiveness is trained when you are looking in the picture very closely to find stars, which are faint enough to hide in its body, being scattered all over the place. Reaching goals is trained because you shall find all the stars of the level to complete it and pass to another one.
It is quite hard to immediately recognize all the stars located in the picture because of two reasons: pictures change each level and the stars are really faint (maybe, only half-tone distinguished from the background saturated with colors and details in order to distract you).
