In front of you on the screen you will see a playing field on which you will see several round cells. One of them will contain a white ball. One of the cells will be highlighted in a specific color. A black ball will appear at the top of the playing field. You can use the mouse to move it to one of the cells. This must be done in such a way that the black ball then pushes the white one, and it ends up in the selected cell. If you manage to do this, then you will be given points in the Black Sphere game and you will move to the next level of the game.
