What is Agario?

Agario is a massively multiplayer online action game created by Brazilian developer Matheus Valadares (also known as “Zeach”), and released in 2015. 
In the game you control a single circular cell and attempt to grow it by absorbing smaller cells (and food pellets), while avoiding being eaten by larger ones. 
The title comes from the substance “agar” (used in Petri-dish culture), which fits the game’s map theme.
