Agar.io
Agar.io is a massively multiplayer online game created by Brazilian developer Matheus Valadares and published by Miniclip. Players control one or more circular cells in a map representing a Petri dish. The goal is to gain as much mass as possible by eating cells and player cells smaller than the player's cell while avoiding larger ones which can eat the player's cells. Each player starts with one cell, but players can split a cell into two once it reaches a sufficient mass, allowing them to control multiple cells. The name comes from the substance agar, used to culture bacteria.

Where Agar.io sits on the grid
The grid places every game in the catalogue on measured axes rather than on an opinion. This is where Agar.io lands on each map it has the data for, with the share of the catalogue it beats on each axis.
- Year
- 83ahead of 41% of the catalogue
- Reach
- 70ahead of 99% of the catalogue
Percentiles are against the games that carry a reading on that axis, not the whole catalogue: counting a game with no figure as a zero would flatter everything that has one. How the grid works.
What readers say about Agar.io
Reviews written by people who have played it. These are separate from the GamingPickz Score and are never averaged into it: that score comes from thousands of Steam reviews with a sample-size correction, and a handful of unverified ratings would distort it rather than improve it.
