• As a small and lone cell, your chief goal is to become larger and larger and then rule the cell-world as soon as possible. How to do this? Guide your little cell by directing the mouse cursor on the screen towards colorful particles. EAT as much as possible in order to increase your size and try to escape from other enemies at the same time. Besides, you should know the influence between the size and the speed. As your cell becomes larger, it will move slower. There is not confusing as the smaller cells need to run fast to get away the bigger ones.
• Still worry? This game also offers some neutral green circles on the screen where the smaller cells can come and hide. But, avoid them if your cell is bigger because you can lose a few smaller pieces and become vulnerable.
