Jack works in the laboratory and is engaged in the development of new species of creatures. Today he will conduct new experiments and you in the game Fyfes will help our hero conduct them. You will see the playing field broken into cells. Some of them will have creatures. Other creatures will appear behind the playing field in various places. Using the control keys, you will direct them inside the playing field. When making moves, try to set one single row of creatures. Then they will disappear from the screen and they will give you points for it.
