Each player is a small bacterium that grows by eating smaller relatives. In the game, you need to try to increase your mass by swallowing smaller bacteria. When the mass is large enough, your bacterium will go to the top (list of the largest bacteria). We get on the usual field. Our little bacterium is surrounded by hexagons and other bacteria.
Some bacteria seem just huge. On the phone screen, the role of the mouse is played by a finger or a stylus. With one move you can change the direction of the ball. You can keep your finger on and lead the bacterium anywhere, or you can simply give it a direction and it will move by itself.
Just like in the computer version, there are only two buttons on the phone screen. The first splits your bacterium into two parts, pushing one of the parts forward with acceleration, and the second separates small particles from the bacterium. They can lure smaller bacteria or feed them.
