In the new Galaxy Stones game, you can test your attentiveness and reaction speed. You will see a stone niche on the screen. A stone will fly in it at a certain speed. Hitting the walls and ceiling, he will change the path of his flight. A mobile platform will be visible at the other end of the field. You must use the control keys to move it around the playing field and substitute it under a stone. Thus, you will beat him off and not let him leave the niche.
