Overview

The IO gaming trend began in April 2015 with the release of Agar.io, a shared online game that was based on how microbes behave. In Agari.io, players are in a situation where they must eat or be eaten. They move around a map to find food and grow bigger. Eventually, they get big enough to start eating the smaller cells of other players. But they have to keep an eye out for bigger players who might try to hurt them.
